Barriers and facilitators to the implementation of physical activity policies in schools: A systematic review

Stakeholders' perspectives on barriers and facilitators to implementing extra physical activity in secondary schools to improve adolescents' health and academic performance

Introduction

There is an association between physical activity and both health and academic performance. However, there is still a lack of consensus on how to engage adolescents in physical activity interventions in secondary schools. One approach to better understand the activities and strategies supporting effective implementation is to involve school staff and adolescents in the early stages of planning and preparing for interventions. Therefore, the aim of this study is to explore how multiple stakeholders, including school staff, students, and experts, perceive the barriers and facilitators for implementing a school-based intervention that extends the school day with additional physical activity in Sweden.

Material and methods

This inductive explorative qualitative study involved 16 participants. Three focus groups with school staff, including principals (n = 3), teachers (n = 6), and students (n = 4), and three interviews with experts were conducted. The planned intervention and its components were presented to the participants in the focus group and interviews to discuss them based on their previous experiences and thoughts of implementing physical activities or health promotion programmes in their schools or with adolescents. Data were analysed using qualitative content analysis.

Results

Three categories emerged: (1) "types of activities offered", highlighting the importance of designing activities that are fun, inclusive and unusual; (2) "integration of the activities into school curriculum" to promote sustainability of the intervention and incorporate physical activity throughout the school day and across school subjects, and (3) "Management support and funding" referring to the funded time and facilities that teachers leading the activities need to facilitate implementation.

Conclusions

Before implementing extra physical activity in a school setting, it is important to understand what activities enhance students' motivation and the type of support teachers need from the school principal and administration. This includes funding for teachers' time, appropriate scheduling of the activities, and access to facilities.

The FIT FIRST 10 dose-response study: evaluation of implementation outcomes

Introduction

Increasing physical activity (PA) levels among children is critical to mitigate health risks associated with physical inactivity. Schools have been highlighted as ideal setting for promoting PA. However, existing school-based PA programs often face implementation challenges. The FIT FIRST 10 (FF10) multi-sport program has been introduced in Denmark, aiming to increase PA and to enhance children's health, fitness, and well-being. This study evaluates the implementation of the FF10 program for 2nd and 3rd graders.

Materials and methods

The FF10 program was implemented in a 20-week cluster randomized controlled trial across 27 schools. Schools were assigned to a control arm or intervention arms receiving either 3 (full dose) or 1.5 (half dose) FF10 40-min lessons weekly. Teachers received a one-day training session, comprehensive manuals, and necessary equipment. Data were collected from teachers via logbooks documenting implementation fidelity, and an online questionnaire assessing program acceptability, appropriateness, and feasibility, and teachers' capability, opportunity, and motivation for implementing the FF10 program.

Results

A total of 18 intervention schools with 36 classes participated in this study. Program fidelity was high in both intervention groups (2.8 and 2.0 session/week for full and half-dose, respectively). Confidence intervals indicated no differences between the two intervention groups for any outcomes. Teachers (n = 32) in both groups rated FF10 moderately acceptable, appropriate, and feasible (3.5-4.0 out of a potential maximum of 5). Both groups exhibited moderate physical and psychological capabilities (3.5-4.0) and high social opportunities (>4.0), but poor motivation scores (<3.5), particularly regarding the perceived benefits and automatization in delivering the FF10 program.

Conclusion

The FF10 program was almost delivered as intended, but time constraints, limited facilities, and modest teacher motivation might have hindered implementation. Reducing the program's dosage did not improve implementation outcomes, emphasizing the need for ongoing support to boost teacher motivation and integration of the program into school timetables.

Implementation Outcomes and Recommendations of Two Physical Activity Interventions: Results from the Danish ACTIVE SCHOOL Feasibility Study

Physical activity (PA) should be an essential part of all children's lives, as it can promote physical and mental health, enhance general well-being, and positively impact learning outcomes. Schools offer an ideal setting to encourage physical activity during the school day, as nearly all children attend school. However, schools present a complex environment for implementing PA, and sedentary behavior is common in classroom teaching. This study explores the feasibility of two types of school-based physical activity interventions: one based on research in exercise and cognition (Run, Jump & Fun) and another grounded in embodied learning (Move & Learn). Run, Jump & Fun can be conceptualized as extra non-curricular physical activity implemented into the school day while Move & Learn is integrated into curricular time. The 8-week study involved third-grade students and their teachers from seven schools, with educational strategies applied to support adoption. Quantitative and qualitative data were collected before, during, and after the 8-week period. The results indicated that both interventions were feasible to implement, leading to a series of recommendations for further refinement. These recommendations can guide the development of future school-based PA interventions and inspire other researchers to assess and improve their implementation strategies.

Physical Literacy, According to the World Health Organization (WHO), in an Italian Preschool and Education for a Daily Movement Routine

BACKGROUND AND OBJECTIVES

The preschool context produces excessive sedentary behavior in children. The systematic fulfillment of structured physical activities during school time, namely a daily movement routine (DMR), can contribute to increasing the quantity of physical activity (PA) and to improving physical literacy (PL), reaching the WHO's recommendations.

AIM

The present study aims to quantify the sedentary time spent by 4- and 5-year-old preschool children and to verify the effects that a DMR could have on sedentary habits in preschool children.

METHOD

An experimental observational study was carried out. Ad hoc questionnaires were administered to parents, teachers, and children, and an observation checklist was used to quantify the time spent in sedentary activities at school. Descriptive statistics and t-tests were applied for data analysis.

RESULTS

Thirty-two children attending Italian preschool participated in this study. The implementation of a DMR significantly reduced the sedentary time in preschool, decreasing the time spent sitting by 45.69% and increasing the time spent standing by 185%.

CONCLUSIONS

This study confirms the hypothesis that children move for less time than recommended by the WHO and highlights the importance of making the experiences of the DMR structural, as this could be an opportunity for educational processes to enhance active lifestyles in promoting the development of physical literacy.

Student perceptions of U.S. based school day physical activity best practices in relation to accelerometer-based sedentary behavior and activity

Objective

To examine associations between student perceptions of school physical activity best practices and accelerometer-based physical activity during school days.

Methods

The sample was 758 students in grades 3rd-4th or 6th-7th (female-58 %; 31 % Black/African American) from 33 schools across five school districts in a Mid-Atlantic state in the U.S. Students completed the Perceptions of the Environment at School survey to assess perceived implementation of 11 school physical activity best practices and wore an Actical ankle accelerometer for 7 days between 2017 and 2019. Accelerometer cutpoints were applied for percent time in sedentary, light, and moderate-vigorous physical activity (MVPA) during school hours. Adjusted mixed effects linear regression models were used to predict percent time in each physical activity category, with separate models for elementary and middle school.

Results

More best practices were perceived by elementary versus middle schoolers (sum score = 3.3 versus 1.5, p < .01). For every additional best practice perceived, elementary schoolers spent 0.64 % less time in sedentary behavior (B = -0.62; SE = 0.27, p = .02), equivalent to ∼12 fewer minutes/week in sedentary behaviors, and 0.58 % more time in light activity (B = 0.58; SE = 0.25, p = .02; ∼10 more minutes/week). No associations observed for middle schoolers or MVPA.

Conclusions

Few best practices were perceived as being implemented in school. Elementary schoolers who perceived more best practices spent more time in light activity and less in sedentary behavior, but this relationship was not found among middle schoolers. Future research should promote implementation of school physical activity best practices and examine the linkage between implementation, student perceptions, and behavior change.Trial Registration: Clinical Trials, NCT03432715; Registered on 02/2/2018.

Strategies for enhancing the implementation of school-based policies or practices targeting diet, physical activity, obesity, tobacco or alcohol use

BACKGROUND

A range of school-based interventions are effective in improving student diet and physical activity (e.g. school food policy interventions and classroom physical activity interventions), and reducing obesity, tobacco use and/or alcohol use (e.g. tobacco control programmes and alcohol education programmes). However, schools are frequently unsuccessful in implementing such evidence-based interventions.

OBJECTIVES

The primary review objective is to evaluate the effectiveness of strategies aiming to improve school implementation of interventions to address students' (aged 5 to 18 years) diet, physical activity, obesity, tobacco use and/or alcohol use. The secondary objectives are to: 1. determine whether the effects are different based on the characteristics of the intervention including school type and the health behaviour or risk factor targeted by the intervention; 2. describe any unintended consequences and adverse effects of strategies on schools, school staff or students; and 3. describe the cost or cost-effectiveness of strategies.

SEARCH METHODS

We searched CENTRAL, MEDLINE (Ovid), Embase (Ovid), five additional databases, the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP), and the US National Institutes of Health registry (clinicaltrials.gov). The latest search was between 1 May 2021 and 30 June 2023 to identify any relevant trials published since the last published review.

SELECTION CRITERIA

We defined 'implementation' as the use of strategies to adopt and integrate evidence-based health interventions and to change practice patterns within specific settings. We included any randomised controlled trial (RCT) or cluster-RCT conducted on any scale, in a school setting, with a parallel control group that compared a strategy to improve the implementation of policies or practices to address diet, physical activity, obesity, tobacco use and/or alcohol use by students (aged 5 to 18 years) to no active implementation strategy (i.e. no intervention, inclusive of usual practice, minimal support) or a different implementation strategy.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methods. Given the large number of outcomes reported, we selected and included the effects of a single outcome measure for each trial for the primary outcome using a decision hierarchy (i.e. continuous over dichotomous, most valid, total score over subscore). Where possible, we calculated standardised mean differences (SMDs) to account for variable outcome measures with 95% confidence intervals (CI). We conducted meta-analyses using a random-effects model. Where we could not combine data in meta-analysis, we followed recommended Cochrane methods and reported results in accordance with 'Synthesis without meta-analysis' (SWiM) guidelines. We conducted assessments of risk of bias and evaluated the certainty of evidence (GRADE approach) using Cochrane procedures.

MAIN RESULTS

We included an additional 14 trials in this update, bringing the total number of included trials in the review to 39 trials with 83 trial arms and 6489 participants. Of these, the majority were conducted in Australia and the USA (n = 15 each). Nine were RCTs and 30 were cluster-RCTs. Twelve trials tested strategies to implement healthy eating practices; 17 physical activity, two tobacco, one alcohol, and seven a combination of risk factors. All trials used multiple implementation strategies, the most common being educational materials, educational meetings, and education outreach visits, or academic detailing. Of the 39 included trials, we judged 26 as having high risks of bias, 11 as having some concerns, and two as having low risk of bias across all domains. Pooled analyses found, relative to a control (no active implementation strategy), the use of implementation strategies probably results in a large increase in the implementation of interventions in schools (SMD 0.95, 95% CI 0.71, 1.19; I2 = 78%; 30 trials, 4912 participants; moderate-certainty evidence). This is equivalent to a 0.76 increase in the implementation of seven physical activity intervention components when the SMD is re-expressed using an implementation measure from a selected included trial. Subgroup analyses by school type and targeted health behaviour or risk factor did not identify any differential effects, and only one study was included that was implemented at scale. Compared to a control (no active implementation strategy), no unintended consequences or adverse effects of interventions were identified in the 11 trials that reported assessing them (1595 participants; moderate-certainty evidence). Nine trials compared costs between groups with and without an implementation strategy and the results of these comparisons were mixed (2136 participants; low-certainty evidence). A lack of consistent terminology describing implementation strategies was an important limitation of the review.

AUTHORS' CONCLUSIONS

We found the use of implementation strategies probably results in large increases in implementation of interventions targeting healthy eating, physical activity, tobacco and/or alcohol use. While the effectiveness of individual implementation strategies could not be determined, such examination will likely be possible in future updates as data from new trials can be synthesised. Such research will further guide efforts to facilitate the translation of evidence into practice in this setting. The review will be maintained as a living systematic review.

Primary School Pupils' Perceptions and Experiences of Wearable Technologies

BACKGROUND

Wearable technologies offer new opportunities to address in-school physical inactivity. However, children are often excluded from discussing issues which directly impact them, including the use of wearable technologies in a school setting. Thus, the aim of this study is to understand primary school pupils' experiences and perceptions of using wearable physical activity monitoring technologies within schools.

METHODS

Nine semi-structured focus groups were conducted with 41 Year 5 and 6 pupils (19 girls, 22 boys) from 5 primary schools in the South West of England. Focus group transcripts were analyzed using a reflective thematic approach.

RESULTS

Pupils made valuable contributions to discussions around wearable technologies, considering both advantages and disadvantages. Most importantly, when discussing use in schools, pupils were mindful that while they wanted to see their own activity and saw benefit in teachers knowing their activity, they felt comparisons in classes could lead to negative emotions for some pupils.

CONCLUSION

The findings from this study can contribute to a more detailed understanding of pupils' perspectives, which can help inform school-based interventions which aim to address physical inactivity and associated inequalities. Instead of using wearable devices for individual pupil ownership, schools should access data-insights with the intention of changing school practices.

Effects of video-guided active breaks with curricular content on mental health and classroom climate in chilean schoolchildren aged 6 to 10: study protocol for a multicentre randomized controlled trial

Background

The incidence of mental health issues in children is increasing worldwide. In Chile, a recent surge in reports of deteriorating mental health among school populations and an increase in complaints related to poor school climate have been observed. Physical activity, specifically active breaks in the classroom, has shown positive effects on children's health. However, evidence regarding its impact on mental health and school climate in children is limited.

Objective

This work outlines the design, measurements, intervention program, and potential efficacy of the "Active Classes + School Climate and Mental Health" project. This project will assess a 12-week program of active breaks through guided videos with curricular content in the school classroom, and its effects on mental health and school climate as its primary indicators. Additionally, it will measure physical activity, physical fitness, motor competence, and academic performance in students aged 6-10 years in the Biobío province, Chile, as secondary indicators. Methodology: A multicenter randomized controlled trial involving 823 students from 1st to 4th grade (6-10 years old), six schools (three intervention and three control) will be conducted in the Biobío region, Chile. Participants belonging to the intervention group will implement video-guided active breaks through the "Active Classes" web platform, featuring curricular content, lasting 5-10 min and of moderate to vigorous intensity physical activity, twice a day, Monday to Friday, over a span of 12 weeks. Expected Results/Discussion: To our knowledge, this will be the first study in Chile to evaluate the effects of incorporating video-guided active breaks with curricular content on mental health variables and school climate in schoolchildren. Thus, this study contributes to the scarce evidence on the effects of video-guided active breaks on mental health variables and school climate in schoolchildren worldwide. Additionally, it will provide crucial information about active teaching methodologies that have the potential to positively contribute to the wellbeing of students, thus addressing the problems of mental health and climate in Chilean schools.

Development and evaluation of the Capability, Opportunity, and Motivation to deliver Physical Activity in School Scale (COM-PASS)

BACKGROUND

Teachers are recognized as 'key agents' for the delivery of physical activity programs and policies in schools. The aim of our study was to develop and evaluate a tool to assess teachers' capability, opportunity, and motivation to deliver school-based physical activity interventions.

METHODS

The development and evaluation of the Capability, Opportunity, and Motivation to deliver Physical Activity in School Scale (COM-PASS) involved three phases. In Phase 1, we invited academic experts to participate in a Delphi study to rate, provide recommendations, and achieve consensus on questionnaire items that were based on the Capability, Opportunity, and Motivation Behavior (COM-B) model. Each item was ranked on the degree to which it matched the content of the COM-B model, using a 5-point scale ranging from '1 = Poor match' to '5 = Excellent match'. In Phase 2, we interviewed primary and secondary school teachers using a 'think-aloud' approach to assess their understanding of the items. In Phase 3, teachers (n = 196) completed the COM-PASS to assess structural validity using confirmatory factor analysis (CFA).

RESULTS

Thirty-eight academic experts from 14 countries completed three rounds of the Delphi study. In the first round, items had an average rating score of 4.04, in the second round 4.51, and in the third (final) round 4.78. The final tool included 14 items, which related to the six constructs of the COM-B model: physical capability, psychological capability, physical opportunity, social opportunity, reflective motivation, and automatic motivation. In Phase 2, ten teachers shared their interpretation of COM-PASS via a 20-min interview, which resulted in minor changes. In Phase 3, CFA of the 3-factor model (i.e., capability, opportunity, and motivation) revealed an adequate fit to the data (χ2 = 122.6, p < .001, CFI = .945, TLI = .924, RMSEA = .066). The internal consistencies of the three subscale scores were acceptable (i.e., capability: α = .75, opportunity: α = .75, motivation: α = .81).

CONCLUSION

COM-PASS is a valid and reliable tool for assessing teachers' capability, opportunity, and motivation to deliver physical activity interventions in schools. Further studies examining additional psychometric properties of the COM-PASS are warranted.

Process Evaluation of a Scaled-Up School-Based Physical Activity Program for Adolescents: Physical Activity 4 Everyone

BACKGROUND

Physical Activity 4 Everyone (PA4E1) is a whole-school physical activity program, with demonstrated efficacy (2012-2014). PA4E1 was adapted (scaled-up) and tested in a scale-up trial (2017-2020). This process evaluation study of the scale-up trial had 2 aims. First, to describe the acceptability, appropriateness, and feasibility of PA4E1 in the scale-up trial, from the perspective of school staff involved in the program management and delivery. Second, to generate themes that may explain school staff assessments of acceptability, appropriateness, and feasibility.

METHODS

Data were collected at various time points throughout the 2-year implementation phase. Online surveys were collected from In-School Champions, Head Physical Education teachers, Principals, and Physical Education teachers (quantitative data). Focus groups and interviews were conducted with In-School Champions, Principals, and Physical Education teachers (qualitative data). Existing published data on website engagement, adaptations, modifications, and the scale-up trial primary outcome (implementation of physical activity practices) were triangulated with the quantitative and qualitative during analysis, to generate themes.

RESULTS

School staff delivering PA4E1 reported it was highly acceptable, appropriate, and feasible. Seven themes were generated relating to acceptability, appropriateness, and feasibility. The themes related to how the program was funded, the delivery modes of implementation support, the identification of easy-wins, the recruitment of the right in-school champion, facilitating principal buy-in, mitigating the impact of school staff turnover, and engaging the whole school.

CONCLUSIONS

Recommendations are made to inform future adaptations for PA4E1 and potentially school-based physical activity programs more generally. The findings may inform future scalability assessments of the suitability of programs for scale-up.

The Secret Sauce? Taking the Mystery Out of Scaling-Up School-Based Physical Activity Interventions

Over the last 4 decades, physical activity researchers have invested heavily in determining "what works" to promote healthy behaviors in schools. Single and multicomponent school-based interventions that target physical education, active transportation, and/or classroom activity breaks effectively increased physical activity among children and youth. Yet, few of these interventions are ever scaled-up and implemented under real-world conditions and in diverse populations. To achieve population-level health benefits, there is a need to design school-based health-promoting interventions for scalability and to consider key aspects of the scale-up process. In this opinion piece, we aim to identify challenges and advance knowledge and action toward scaling-up school-based physical activity interventions. We highlight the key roles of planning for scale-up at the outset, scale-up pathways, trust among partners and program support, program adaptation, evaluation of scale-up, and barriers and facilitators to scaling-up. We draw upon our experience scaling-up effective school-based interventions and provide a solid foundation from which others can work toward bridging the implementation-to-scale-up gap.

Effects of School-Based High-Intensity Interval Training on Hemodynamic Parameters and Heart Rate Variability: A Randomized Controlled Trial

ABSTRACT

Ketelhut, S, Ketelhut, K, Ketelhut, SR, and Ketelhut, RG. Effects of school-based high-intensity interval training on hemodynamic parameters and heart rate variability: A randomized controlled trial. J Strength Cond Res 38(6): 1033-1040, 2024-The purpose of this study was to assess the effects of a child-specific school-based high-intensity interval training (HIIT) implemented into physical education (PE) classes on various hemodynamic parameters and heart rate variability indices. Forty-six students (age 11 ± 1 year) were randomized into an intervention (INT n = 22) and a control group (CON n = 24). During a 12-week period, the INT and CON groups participated in regular PE twice weekly (45-90 minutes). The INT group received HIIT during the first 20 minutes of the 2 PE classes. Systolic and diastolic blood pressure, total peripheral resistance, aortic pulse wave velocity (aPWV), heart rate, SD of normal to normal heartbeat intervals, the root mean square of successive differences between normal heartbeats (RMSSD), the proportion of differences between adjacent normal to normal heartbeat intervals of more than 50 ms, low-frequency power, high-frequency power, and the LF/HF ratio were assessed before and after the experimental period. A p value ≤0.05 was considered statistically significant. Forty students (20 INT; 20 CON) were included in the analysis. A significant time × group interaction was detected for aPWV ( p = 0.05, η2 = 0.099), RMSSD ( p = 0.010, η2 = 0.161), low-frequency power ( p = 0.009, η2 = 0.165), high-frequency power ( p < 0.001, η2 = 0.272), and the LF/HF ratio ( p < 0.001, η2 = 0.354). The INT group revealed significant improvements for the respective parameters. School-based HIIT can induce improvements in cardiovascular parameters. These results highlight the potential of embedding HIIT within the school setting, offering a time-efficient exercise intervention.

Preliminary Program Evaluation of Pocket PE 3-5™, A User-Friendly Digital Application for Teacher Skills Training and Physical Education Activities for Third- to Fifth-Grade Elementary Students

BACKGROUND

In the United States, many classroom teachers also teach physical education (PE). However, there is a dearth of evidence- and standard-based PE programs designed to support classroom teachers to deliver PE effectively in schools.

METHODS

The purpose of this study was to establish proof-of-concept for the Pocket PE 3-5 digital app in school settings with 10 third- to fifth-grade classroom teachers. We assessed fidelity of program implementation, measured via observations of PE quality. Students used wrist-worn heart rate monitors during Pocket PE 3-5 lessons to measure time spent in moderate to vigorous physical activity. Program feasibility was primarily assessed through teacher-reported surveys of usability, satisfaction, and acceptability and exit interviews.

RESULTS

Mean PE observation scores were 18.6 (SD = 1.5) on a scale of 5 to 20. On average, students spent 56.7% (SD = 13.1%) of class time engaging in moderate to vigorous physical activity. Mean survey scores, reported on a 5-point scale, were 4.5 (SD = 0.6) for acceptability, 4.8 (SD = 0.4) for usability, and 4.7 (SD = 0.7) for satisfaction. Teachers liked how easy the app was to use but mentioned some technological challenges.

CONCLUSIONS

This program evaluation study established the proof-of-concept for the Pocket PE 3-5 elementary school PE program.

The Effectiveness of Physical Activity Policies in Center-Based Childcare: A Systematic Review and Meta-Analysis

Purpose: Many young children spend a significant portion of time in center-based childcare settings; however, these children are often not sufficiently active during care. Promoting physical activity through policy implementation is one mechanism which has the potential to increase physical activity. The purpose of this systematic review and meta-analysis was to provide an overview of physical activity policies implemented in childcare centers and determine their effect on children's physical activity. Methods: Electronic searches were conducted in CINAHL, Medline, PsycINFO, EMBASE, Scopus, SPORTDiscus, and Sports Medicine and Education Database. Two reviewers independently examined 3,286 articles to find peer-reviewed, original studies that assessed the impact of physical activity policies on children's physical activity. Random effects meta-analyses were used to determine the impact of policies. Results: A total of 13 articles met the inclusion criteria; in which 12 unique policies were implemented. Results of the meta-analyses suggest that introducing new physical activity policies did not increase children's moderate-to-vigorous physical activity (MVPA); however, compared to centers without a formalized physical activity policy, children in centers with a formalized policy engaged in significantly more MVPA and total physical activity. Conclusions: Introducing new physical activity policies alone may not be sufficient to increase children's engagement in physical activity, and it may be important to combine with capacity-building initiatives for childcare staff and early childhood educators. Results reinforce the value of childcare centers implementing their own formalized physical activity policies to support children's physical activity, which highlights the importance of regulating physical activity practices in childcare.

Effect of capacity building interventions on classroom teacher and early childhood educator perceived capabilities, knowledge, and attitudes relating to physical activity and fundamental movement skills: a systematic review and meta-analysis

BACKGROUND

Capacity building may play an important role in improving classroom teachers' and early childhood educators' (ECE) capacity to implement physical activity and FMS interventions. Capacity building is the development of knowledge, skills, and structures to improve the capability of individuals and organisations to achieve effective health promotion. This review aimed to determine the efficacy of capacity building interventions on teachers' and ECEs' perceived capabilities, knowledge, and attitudes relating to physical activity and fundamental movement skills.

METHODS

An exhaustive literature search of six electronic databases was conducted. Controlled, single-group pre-post studies were included if they measured the effect of a capacity building intervention on in-service or pre-service classroom teachers' (primary or secondary) or ECEs' physical activity or fundamental skills related perceived capabilities, knowledge, or attitudes. The effects of interventions were synthesised using random effects meta-analysis. Subgroup analysis and meta-regression was conducted to determine if the effects differed based on study design, type of teacher (ECE vs. primary school), or teacher level (pre-service vs. in-service).

RESULTS

A total of 22 studies reporting on 25 unique samples were included in the meta-analyses. Only studies reporting on ECEs and primary school teachers were identified. Interventions most commonly included training/professional development, resources and toolkits, communities of practice, mentorships, and ongoing support. Results showed that capacity building interventions significantly improved teachers' and ECEs' perceived capabilities (g = 0.614, 95% CI = 0.442, 0.786), knowledge (g = 0.792 95% CI = 0.459, 1.125), and attitudes (g = 0.376 95% CI = 0.181, 0.571). The effects did not differ significantly as a function of any of the moderators examined.

CONCLUSION

Findings from this review provide strong support that capacity building interventions are efficacious at improving teachers' and ECEs' perceived capabilities, knowledge, and attitudes related to promoting physical activity and teaching fundamental movement skills. Pre-service teachers and ECEs should be provided training in physical activity and fundamental movement skills as part of their degrees, and continual professional development and capacity building should be offered to in-service teachers and ECEs to promote physical activity and fundamental movement skills in children.

To move or not to move while on campus: Examining the influence of others

OBJECTIVE

To examine the influence of dynamic and trending descriptive norms on increasing physical activity and decreasing the sedentary behaviors of university students while on campus.

PARTICIPANTS

One-hundred fifty-six university students from a Canadian university completed this study.

METHODS

Participants were randomly assigned to receive one of four online messages containing normative information about the on-campus behavior of university students. On-campus physical activity and sedentary behavior were measured pre- and post-message.

RESULTS

The results revealed that students exposed to the trending norm reported a greater decrease in sedentary behavior than students in the control condition, p = .007.

CONCLUSION

Results provide preliminary experimental evidence that trending norm messages may serve to decrease the sedentary behavior of students while on campus.

Educator-Perceived Barriers and Facilitators to Structured-Physical Activity in Early Childhood Centres: A Systematic Review

Purpose: Physical activity (PA) and motor competence development are vital for young children, yet many early childhood education and care (ECEC) centers struggle to successfully implement PA programs, particularly those organized and led by educators. This review aimed to synthesize qualitative literature to (1) identify educator-perceived barriers and facilitators to structured-PA in ECEC centers, and (2) map these to the COM-B model and Theoretical Domains Framework (TDF). Methods: Following PRISMA guidelines, a systematic search of five databases was conducted in April 2021 and updated in August 2022. Records were screened in Covidence software using predefined eligibility criteria. Using the framework synthesis method, data extraction and synthesis were conducted in coding forms in Excel and NVivo. Results: Of 2382 records identified, 35 studies were included, representing 2,365 educators across 268 ECEC centers in 10 countries. Using the COM-B model and TDF, an evidence-informed framework was developed. Findings revealed the greatest barriers concerned educator "opportunity" (e.g. competing time and priorities, policy tensions, indoor/outdoor space constraints) and "capability" (e.g. lack of PA knowledge and practical, hands-on skills) to implement structured-PA. Although fewer studies reported factors that influenced educator "motivation", several themes intersected across the three COM-B components illustrating the complexity of behavioral determinants in this setting. Conclusions: Interventions grounded in theory that utilize a systems approach to target multiple levels of influence on educator behavior, and are flexible and adaptable locally, are recommended. Future work should seek to address societal barriers, structural challenges in the sector, and the PA educational needs of educators. PROSPERO Registration: CRD42021247977.

Exploring the Use of a Learning-Based Exergame to Enhance Physical Literacy, Soft Skills, and Academic Learning in School-Age Children: Pilot Interventional Study

BACKGROUND

There is ample evidence that most children do not perform enough physical activity (PA). To address this major public health problem, the French government implemented 30 minutes of daily PA (DPA) at schools but did not provide any supplemental resources or concrete guidance. Considering both children's interest in video games and the need for teachers to complete their curriculum, the use of a learning-based exergame that combines PA and learning appears particularly relevant.

OBJECTIVE

The first objective of this study was to evaluate the feasibility of implementing 30 minutes of DPA through exergaming among school-age children. The second objective was to examine the effects of an exergaming program on physical literacy, academic learning, and soft skills (motivation, self-efficacy, and concentration).

METHODS

This interventional study had a pre-post design and used the Play LÜ exergame platform. The study included 79 children with a mean age of 8.9 (SD 1.2) years from grade 2 (7 years old) to grade 5 (11 years old). Play LÜ requires players to throw balls against a wall to reach a target or to activate an object and provides an interactive game area for educational activities linked to specific learning themes. After a 4-session familiarization phase during which the teachers chose to prioritize mathematics learning in 30-minute DPA sessions, students took part in DPA sessions over a period of 3 weeks with Play LÜ and a motor skills circuit behind the LÜ setup to keep them continuously active. All sessions were carried out by PA specialists. Each session started with a warm-up using the Grööve application, continued with main activities promoting mathematics learning adapted to each grade level, and ended with a 3-minute meditation for returning to a calm and serene state using the Gaïa application. Before (T0) and after (T1) the program, students completed a self-evaluation booklet to assess their levels of physical literacy, academic performance, and soft skills.

RESULTS

The implementation of this exergaming program was welcomed by the school's administration, teaching staff, and parents. After the program, we observed increased scores for physical literacy (difference +2.6, percentage change +3.6%; W=933.0; P=.002; rrb=-0.39, 95% CI -0.58 to -0.16) and motivation in mathematics (+0.7, +9.8%; W=381.5; P=.005; rrb=-0.44, 95% CI -0.66 to -0.16). In addition, it is important to note that some measures progressed differently across learning levels and age groups.

CONCLUSIONS

The study results indicate positive impacts of learning-based exergaming on physical literacy and motivation in mathematics among school-age children.

Physical activity interventions in European primary schools: a scoping review to create a framework for the design of tailored interventions in European countries

Introduction

Schools provide a unique environment to facilitate physical activity for children. However, many school-based physical activity interventions have not been effective. We propose a new approach, which allows schools to tailor interventions to their specific context. This scoping review aimed to identify intervention components from previous school-based physical activity interventions to form the basis of a tailored approach in a European setting.

Methods

Joanna Briggs Institute guidelines for conducting scoping reviews were followed. European school-based intervention studies aimed at increasing physical activity in children aged 7-11 years published in English since 2015 were included. Databases searched were Ovid Medline, Embase, PsycINFO, Web of Science Social Sciences Citation Index, ERIC and British Education Index. Data was extracted on intervention components, context-related factors (geographical location, school size, child socioeconomic status and ethnicity), feasibility, acceptability and cost-effectiveness. A data-driven framework was developed to summarize the identified intervention components.

Results

79 articles were included, constituting 45 intervention studies. We identified 177 intervention components, which were synthesized into a framework of 60 intervention component types across 11 activity opportunities: six within the school day, three within the extended school day and two within the wider school environment. Interventions most frequently targeted physical education (21%), active and outdoor learning (16%), active breaks (15%), and school-level environmewnt (12%). Of the intervention components, 41% were delivered by school staff, 31% by the research team, and 24% by external organizations. Only 19% of intervention studies reported geographical location and only 10% reported school size. Participant ethnicity and socioeconomic information was reported by 15% and 25%, respectively. Intervention acceptability was reported in 51% of studies, feasibility in 49%, and cost effectiveness in 2%.

Discussion

This review offers a first step in developing a future framework to help schools to develop context-specific, tailored interventions. However, there was a lack of reporting of contextual factors within the included studies, making it difficult to understand the role of context. Future research should seek to measure and report contextual factors, and to better understand the important aspects of context within school-based physical activity.

Examining associations between school-level determinants and the implementation of physical activity opportunities

School-based physical activity (PA) opportunities can help students engage in greater amounts of daily PA, meet PA guidelines, and lead to improved health and educational outcomes. However, we do not completely understand the organizational challenges to implementing these opportunities successfully. This exploratory study examined associations between school-level determinants and the implementation of school-based PA opportunities. We analyzed cross-sectional survey data from schools (n = 46) participating in the Healthy Zone School Program (HZSP) (Dallas, Texas, USA) during 2019-2020. Respondents completed an electronic survey that included measures of school-level determinants (e.g. culture, leadership, priority) and the implementation of school-based PA opportunities. We used linear regression models to examine associations between determinants and implementation outcomes (number of PA opportunities delivered, perceived overall success of each PA program/activity used). After adjusting for campus type (i.e. elementary, middle, high, K-12), student race/ethnicity, and percentage of economically disadvantaged students, no constructs were associated with the number of PA opportunities implemented. Linear regression models suggest access to knowledge and information (β = 0.39, P = .012, 95% CI = 0.24-1.44) and implementation climate (β = 0.34, P = .045, 95% CI = 0.02-1.59) were positively associated with the success of school-based PA opportunities. Our findings provide suggestive evidence that access to knowledge and information and a supportive school climate may improve the overall success of PA opportunities provided to students. Future research should examine additional school-level determinants to understand their importance to implementation and inform the development of strategies to improve schools' capacity for implementing PA opportunities successfully.

Investigating the Potential of a Conversational Agent (Phyllis) to Support Adolescent Health and Overcome Barriers to Physical Activity: Co-Design Study

BACKGROUND

Conversational agents (CAs) are a promising solution to support people in improving physical activity (PA) behaviors. However, there is a lack of CAs targeted at adolescents that aim to provide support to overcome barriers to PA. This study reports the results of the co-design, development, and evaluation of a prototype CA called "Phyllis" to support adolescents in overcoming barriers to PA with the aim of improving PA behaviors. The study presents one of the first theory-driven CAs that use existing research, a theoretical framework, and a behavior change model.

OBJECTIVE

The aim of the study is to use a mixed methods approach to investigate the potential of a CA to support adolescents in overcoming barriers to PA and enhance their confidence and motivation to engage in PA.

METHODS

The methodology involved co-designing with 8 adolescents to create a relational and persuasive CA with a suitable persona and dialogue. The CA was evaluated to determine its acceptability, usability, and effectiveness, with 46 adolescents participating in the study via a web-based survey.

RESULTS

The co-design participants were students aged 11 to 13 years, with a sex distribution of 56% (5/9) female and 44% (4/9) male, representing diverse ethnic backgrounds. Participants reported 37 specific barriers to PA, and the most common barriers included a "lack of confidence," "fear of failure," and a "lack of motivation." The CA's persona, named "Phyllis," was co-designed with input from the students, reflecting their preferences for a friendly, understanding, and intelligent personality. Users engaged in 61 conversations with Phyllis and reported a positive user experience, and 73% of them expressed a definite intention to use the fully functional CA in the future, with a net promoter score indicating a high likelihood of recommendation. Phyllis also performed well, being able to recognize a range of different barriers to PA. The CA's persuasive capacity was evaluated in modules focusing on confidence and motivation, with a significant increase in students' agreement in feeling confident and motivated to engage in PA after interacting with Phyllis. Adolescents also expect to have a personalized experience and be able to personalize all aspects of the CA.

CONCLUSIONS

The results showed high acceptability and a positive user experience, indicating the CA's potential. Promising outcomes were observed, with increasing confidence and motivation for PA. Further research and development are needed to create further interventions to address other barriers to PA and assess long-term behavior change. Addressing concerns regarding bias and privacy is crucial for achieving acceptability in the future. The CA's potential extends to health care systems and multimodal support, providing valuable insights for designing digital health interventions including tackling global inactivity issues among adolescents.

Facilitators and barriers to engaging communities in health service research on dengue control in Indo-Pacific region: a systematic review

BACKGROUND

Dengue is a public health problem in the Indo-Pacific countries. There are concerns over the facilitators and barriers to community engagement in health service research aimed at dengue control. The objective of his study was to identify and synthesize facilitators and barriers to community engagement in health service research aimed at dengue control.

METHODOLOGY

The Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) checklist was used to perform this review. Health-related databases including PubMed, Ovid, and Google Scholar were searched for relevant studies. A consolidated framework with five domains was developed after undertaking a six-phase reflective thematic assessment of the data.

RESULTS

Thirteen studies were identified, spanning eight low-and middle-income countries of the Indo-Pacific region including Cambodia, India, Indonesia, Myanmar, Philippines, Sri Lanka, Thailand, and Vietnam. The studies in this review covered the period from 2002 to 2021. A broad range of study designs and objectives were revealed across these 13 studies. An array of communities such as the local government, project-related health staff, local health services staff, community leaders, local communities/residences/general public, heads of households, community health volunteers, school teachers, and schoolchildren participated in these dengue related studies. The five Consolidated Framework for Implementation Research (CFIR) domains of 'intervention characteristics', 'inner setting', 'outer setting',' individual characteristics', and 'program implementations' were used to identify and describe barriers and facilitators.

CONCLUSIONS

The findings indicate a range of barriers and facilitators to community engagement in dengue control in the selected LMIC in the Indo-Pacific countries. Future health services research on dengue control approaches should be carefully planned, methodologically constructed, aligned with community engagement principles, and involve considerable community participation at all stages of the research.

Evaluating the scaling up of an effective implementation intervention (PACE) to increase the delivery of a mandatory physical activity policy in primary schools

BACKGROUND

Physically Active Children in Education (PACE) is an effective implementation intervention for increasing the number of minutes classroom teachers schedule physical activity each week. To date, evaluations of PACE have included a smaller number of schools from only one region in New South Wales Australia. If PACE is to have population-wide benefits we must be able to deliver this support to a larger number of schools across multiple regions. This study aimed to evaluate the scale-up of PACE.

METHODS

An uncontrolled before and after study, with 100 schools from three regions was conducted. Participating schools received PACE for approximately 12 months. We assessed the following outcomes: delivery of the evidence-based intervention (EBI) (i.e. minutes of physical activity scheduled by classroom teachers per week); delivery of the implementation strategies (i.e. reach, dose delivered, adherence and indicators of sustainability); and key determinants of implementation (i.e. acceptability of strategies and cost). Data were collected via project officer records, and principal and teacher surveys. Linear mixed models were used to assess EBI delivery by evaluating the difference in the mean minutes teachers scheduled physical activity per week from baseline to follow-up. Descriptive data were used to assess delivery of the implementation strategies and their perceived acceptability (i.e. PACE). A prospective, trial-based economic evaluation was used to assess cost.

RESULTS

Delivery of the EBI was successful: teachers increas their average minutes of total physical activity scheduled across the school week by 26.8 min (95% CI: 21.2, 32.4, p < 0.001) after receiving PACE. Indicators for delivery of implementation strategies were high: 90% of consenting schools received all strategies and components (reach); 100% of strategies were delivered by the provider (dose); >50% of schools adhered to the majority of strategies (11 of the 14 components); and acceptability was > 50% agreement for all strategies. The incremental cost per additional minute of physical activity scheduled per week was $27 per school (Uncertainty Interval $24, $31).

CONCLUSIONS

PACE can be successfully delivered across multiple regions and to a large number of schools. Given the ongoing and scalable benefits of PACE, it is important that we continue to extend and improve this program while considering ways to reduce the associated cost.

Personal determinants of change agents' decision-making behavior in community health promotion: a qualitative study

BACKGROUND

Implementing environmental changes to promote healthier communities requires initial positive decisions by change agents from local politics and government. However, there is little research on what influences the change agents' decisions. This explorative, qualitative study aims to identify the personal determinants of the decision-making behavior of local change agents.

METHODS

We conducted semi-structured interviews to assess the personal determinants of decision-making behavior among 22 change agents from local politics and government. Relevant determinants were identified through a structured content analysis of the interview transcripts using the software MAXQDA 2020.

RESULTS

We found the following seven essential clusters of personal determinants of the decision-making behavior of change agents from local politics and government: Imprinting, socialization, and biography; experiences and involvement; attitudes and outcome expectations towards important issues and aspects; knowledge; emotions; personal benefits; and the perceived influences of others.

CONCLUSIONS

The identified personal determinants might serve as a source of understanding the decision-making behavior of change agents in community decision-making processes. Our findings can contribute to the effective planning and implementation of evidence-based multilevel interventions related to changing environmental conditions in communities and provide important information on which personal determinants should be considered when derive strategies for community health promotion within a systematic approach of developing an intervention program theory.

Physical Activity Interventions During the School Day: Reviewing Policies, Practices, and Benefits

BACKGROUND

There are many ways to increase physical activity (PA) during the school day as part of a Comprehensive School Physical Activity Plan. This article reviews policies and practices that can be used during the school day to increase PA for students.

METHODS

We searched systematic reviews for articles that met criteria (2010-2018, phase 1), followed by a search for individual articles addressing topics for which we did not identify a sufficiently relevant or recent review or to update an earlier review that concluded insufficient evidence (2010-2020, phase 2). We included 45 articles (45 studies, 54 interventions).

RESULTS

We grouped studies by intervention type: school-wide PA approaches to reach all students within the school setting (17), physical education (PE) interventions (13), and interventions related to recess (15). Few studies involved secondary schools or rural settings. Among 45 studies reporting PA behavior or fitness outcomes, 37 reported at least 1 improvement.

CONCLUSIONS

PA policies, PE, and recess can help improve school health by increasing the PA levels of students.

Facilitators and barriers to physical activity among English adolescents in secondary schools: a mixed method study

Background

It is evident that physical activity (PA) programmes implemented in schools were not effective in improving PA behaviours among adolescents. This study investigated students' perceptions of barriers to PA among inactive English adolescents in secondary schools based on the Capability, Opportunity, Motivation, and Behaviour (COM-B) model, the Behaviour Change Wheel (BCW), and Theoretical Domains Framework (TDF). The study compared barriers faced by inactive and active groups participating in sports and PA in secondary schools to identify sources of behaviour contributing to inactivity.

Methods

A pre-intervention online survey was distributed to affiliated schools by 233 Teaching Schools Alliances (TSAs) as part of the monitoring and evaluation of the Secondary Teacher Training study. Data were cross-tabulated to analyse activity levels and behavioural barriers for active and inactive groups, using the COM-B domains. The research team followed a seven-step process to categorise barriers based on their relevant domain in the TDF mapped to the COM-B.

Results

The findings were derived from one of the most extensive surveys of adolescents ever undertaken involving 200,623 active and 8,231 inactive respondents. The study identified 52 barriers and 68 behaviours that prevent adolescents from participating in PA. Psychological and social barriers were found to affect all activity levels, genders, and ethnic groups, with a lack of confidence and self-consciousness being the most prevalent. Certain demographic groups, such as those from minority ethnic groups and disabled individuals, were found to be overrepresented among inactive populations. The finding of the study indicated that there were common barriers that affected both inactive and active groups, with further similarity when examining barriers between active and inactive girls. The study also found that girls were more likely to experience the main barriers compared to boys, while inactive boys were more likely to encounter these barriers compared to active boys. The findings suggest that common barriers could be addressed across the population, while recognising some differences in demographics, and the need to provide personalised support. Targeted interventions are also suggested for all girls and inactive boys.

Conclusion

This study highlights the range of barriers that impact adolescents and provides insight into potential mechanisms for behaviour change, including intervention functions, policy categories, and evidence-based behaviour change tools. The study highlights the need for further research to address the barriers to PA among adolescents, particularly those who are inactive. Utilising the findings of this study, future research should investigate the effectiveness of novel digital exercise interventions and policies in increasing PA levels among children and adolescents. Complex digital exercise interventions, including conversational AI solutions, could provide personalised tools to identify and revolutionise support around the multitude of barriers that impact adolescents globally."For the purpose of open access, the author has applied a Creative Commons Attribution (CC BY) licence to any Author Accepted Manuscript version arising from this submission."

School-based physical education, physical activity and sports provision: A concept mapping framework for evaluation

OBJECTIVE

Physical education, physical activity and sports provision are important factors in whole school health promotion, however, a standardised evaluation framework to evaluate the contribution of these components is lacking. A framework that accounts for the distinct structures and associated factors, that impact upon provision would facilitate a more coherent evaluation.

METHODS

A concept mapping methodology, involving the generation of factors relevant to school physical education, physical activity and sports provision and their subsequent thematic and numeric rating and sorting was utilised. Concept mapping effectively gathers, integrates, and visually and numerically represents the composite thinking of a group of relevant and expert stakeholders around a complex social phenomenon. Following a review of the extant literature and synthesis among 20 expert stakeholders, a list of 95 factor statements relevant to school physical education, physical activity and sports provision were developed.

RESULTS

Each factor statement was rated and sorted by 197 multi-disciplinary participants. An eight-cluster framework that demonstrated good validity (stress value: 0.266), was derived from the data based on: 1. Partnerships and Pupil Centered Physical Education; 2. Physical Activity and Sports; 3. School Demographics; 4. Equipment, Facilities and Budget; 5. Extra Costs; 6. Curriculum and Policy; 7. School Management and 8. Timetable. Statements within the cluster on school management received the highest mean importance and modifiability ratings while statements within the cluster on school demographics received the lowest mean importance and modifiability ratings.

CONCLUSIONS

Eight overarching structures which account for school physical education, physical activity and sports provision have been identified. Within each of these, structures and overall factors of greatest importance and modifiability have been illuminated. Findings stemming from this rigorous methodology, provide the foundation for the development of a national provision evaluation index to inform both school-level and national policy and actions. It is recommended the current methodology is replicated in other nations to gain corresponding insights.

National policies on physical activity from 64 countries with different economies: a scoping review with thematic analysis

In 2018, the World Health Organization (WHO) launched a Global Action Plan on Physical Activity (PA), which included 20 policy actions for creating active societies, environments, people and systems. The objective of this scoping review was to summarize the themes/contents of national PA policies/plans conforming to the WHO's proposals and the country's economy. This review followed Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines for scoping reviews. A systematic search of electronic databases (Web of Science, Medline/PubMed, LILACS, PsycINFO, Scopus and SPORTDiscus) and 441 government documents/websites from 215 countries/territories was conducted (February 2021). Documents on national-level policies, published in English, Spanish and Portuguese since 2000, were eligible. The information on content and structure was systematically extracted and summarized into dimensions proposed by the WHO: active societies, environments, people and systems. The search identified 888 article references and 586 potentially relevant documents. After the screening, 84 policy documents from 64 countries were eligible. Most documents (n = 46) provided detailed PA policies/plans amid other health topics (e.g. non-communicable diseases, named 'general documents'), and 38 were PA-specific. The content analysis merged 54 visions, 65 missions, 108 principles, 119 objectives, 53 priorities, 105 targets, 126 indicators and 1780 actions/strategies from 38 PA-specific and 46 general documents. Among the PA-specific documents, the active system's dimension was the most contemplated in the principles (n = 43), priorities (n = 51) and action/strategies (n = 530) elements. At the same time, the objectives (n = 39), targets (n = 52) and indicators (n = 58) presented contents more frequently related to the active people dimension. For the general documents, all principles (n = 4), objectives (n = 14) and priorities (n = 7) were related to the dimension of active people, while target (n = 51), indicator (n = 53) and actions/strategies (n = 292) elements presented content related to all dimensions. The increase in countries with national PA policies/plans should be followed by improving the current ones because important dimensions seem to be not considered in these documents. This will facilitate a global PA agenda that considers the complexity and multidimensionality of PA promotion.

Comparative effectiveness of school-based exercise interventions on physical fitness in children and adolescents: a systematic review and network meta-analysis

Background

Schools provide a favorable setting for health education, however, the most effective school-based exercise mode for improving physical fitness remains unclear. This network meta-analysis was designed to assess and rank the comparative efficacy of six exercise modalities on physical fitness indicators in a school-based setting.

Methods

An online search of the Web of Science, PubMed, SPORTDiscus, and Scopus databases was conducted. Randomized and quasi-randomized controlled trials were considered. Outcomes included measures of anthropometry and body composition, muscular fitness, and cardiorespiratory fitness. Data were pooled with a random effects model using the frequentist framework.

Results

A total of 66 studies with 8,578 participants (48% girls) were included. High-intensity interval training was the most effective intervention reducing body mass index (mean difference (MD) = -0.60 kg·m^-2, 95% confidence interval (95%CI) = -1.04 to -0.15, p = 0.009), elevating VO_2max (MD = 3.59 mL·kg^-1·min^-1, 95% CI = 2.45 to 4.74, p < 0.001), and 20-meter sprint performance (MD = -0.35 s, 95% CI = -0.55 to -0.14, p = 0.001). Aerobic training had the highest probability of reducing waist circumference (standardized mean difference (SMD) = -0.60, 95% CI = -0.88 to -0.32, p < 0.001). Active video games emerged as a promising modality for improving countermovement jump (MD = 2.43 cm, 95% CI = 0.06 to 4.80, p = 0.041) and shuttle running performance (SMD = 0.86, 95% CI = 0.29 to 1.43, p = 0.003). Strength training was the best exercise mode for improving standing long jump performance (SMD = 1.03, 95% CI = 0.07 to 1.98, p = 0.035) while combined training was rated the first for decreasing body fat percent (MD = -2.56%, 95% CI = -4.73 to -0.40, p = 0.022) and increasing push-up repetitions (SMD = 3.59, 95% CI = 0.81 to 6.37, p = 0.012).

Conclusion

School-based exercise interventions have multiple effects on physical fitness. The findings of this study will help to inform physical education teachers and coaches how best to deliver exercise programs in a school setting. Since the study was limited by the original research, the conclusions will require further verification using high-quality randomized controlled trials.

Barriers and facilitators to physical activity and further digital exercise intervention among inactive British adolescents in secondary schools: a qualitative study with physical education teachers

Background

Previous studies indicated that physical education programs in schools were unsuccessful to ameliorate physical activity (PA) behaviors among adolescents. This study investigated PE teachers' perceptions of barriers and facilitators to PA and further digital exercise interventions among inactive British adolescents in secondary schools based on the Capability, Opportunity, Motivation, and Behavior (COM-B) model, the Behavior Change Wheel (BCW), and Theoretical Domains Framework (TDF).

Method

A qualitative study was conducted among 156 PE teachers in England. deductive thematic analysis approach was applied to analyze data.

Results

A comprehensive perception of PE teachers revealed 21 barriers to PA among inactive adolescents in secondary schools. The study findings show that barriers exist across all categories of the COM-B model in physical opportunity (7), reflective motivation (5), social opportunity (4), psychological capability (4) and physical capability (1). The majority of these barriers were reported in previous studies as being barriers to PA from the perspective of children and adolescents. This shows that the findings are consistent with the views of children and adolescents that participated in these studies. Particular salient barriers for inactive adolescents were reported and greater insight into their experiences was highlighted. The study reported the main sources of behavior, intervention functions, policy functions, and behavior change tools that can be used for future behavior change interventions to support inactive adolescents.

Conclusion

The study recommends using its findings to design interventions for inactive adolescents to achieve recommended levels of physical activity (PA). The study's comprehensive approach and evidence-based solutions provide extensive reference points for future intervention design, informing policy and contributing to enhancing support for inactive adolescents. Further development of digital exercise interventions, including conversational artificial intelligence (AI), is suggested to engage adolescents at scale and provide personalized support to overcome multiple barriers to PA.

The effectiveness of school-based run/walk programmes to develop physical literacy and physical activity components in primary school children: A systematic review

The objectives of this review were to systematically review the research on school-based run/walk programmes and their measurements of physical literacy (PL) and physical activity (PA)-related components and to assess the different intervention methods and their impact on encouraging PL and PA. To be included in the review, studies had to satisfy all inclusion criteria. An electronic search was conducted on six databases, the last date search was 25 April 2022. All outcome measures were grouped using the Shearer et al. (2021) PL checklist and additional PA related outcomes. Ten studies were included in the final review. Five different run/walk interventions were identified and six studies followed or referred to The Daily Mile (TDM) protocol. Outcomes relating to the physical domain were most commonly explored, and no studies explored the cognitive domain. Four studies reported significant differences in cardiovascular endurance measures. Positive findings were also reported for outcomes relating to motivation and self-perception/self-esteem in the affective domain. Overall, run/walk programmes appear to provide promising results in favour of physical and affective development in PL. However, further high-quality studies are needed to draw firm conclusions. This review highlights the popularity of TDM and its potential to contribute to PL development.

Associations between the built environment, policies and curriculum in schools and primary school children’s physical activity

Background: A large proportion of children in the UK do not engage in the recommended amount of physical activity. Schools are an environment where children spend a considerable portion of their time and have the potential to facilitate more physical activity. There has been little exploration of the specific school environment factors that are most pertinent to child physical activity and sedentary behaviour. This study was intended to fill this important gap. Methods: Data were collected between March 2017 and May 2018 from 50 schools and 1223 children who participated in the B-Proact1v cohort study. School level measures were the built environment (e.g. playground equipment, cycling parking, allotments), physical activity-related policies (e.g. policy to encourage active travel) and the use of physical activity in the curriculum (e.g. regular physical activity breaks throughout day). Children’s weekday moderate-to-vigorous physical activity (MVPA) was estimated via Actigraph GT3X accelerometers. Associations between school context measures and children’s weekday MVPA were analysed using linear multilevel models, with children nested within schools, adjusted for individual characteristics. Results: On average, children at schools with allotments, a larger amount of playground equipment and where cycle training was offered, engaged in higher levels of MVPA. PE being compromised due to space was associated with lower levels of MVPA. Conclusions: Whilst there is a need for further exploration, the findings suggest that school-based provision and policies for active travel, sport and active play may be important to encouraging more primary school children to be more active more regularly.

Factors related to the implementation and scale-up of physical activity interventions in Ireland: a qualitative study with policy makers, funders, researchers and practitioners

BACKGROUND

Current literature reports a gap between development of effective interventions to promote physical activity and the systematic uptake into real-world settings. Factors relating to implementation and scale-up of physical activity interventions have been examined, however the perspectives of multiple stakeholders from different domains are not well researched. The purpose of this study was to examine the perceived factors related to physical activity intervention implementation and scale-up in different domains from different stakeholders on the island of Ireland.

METHODS

Practitioners, researchers, funders and policy makers in Ireland were invited to take part in a semi-structured interview exploring factors related to the implementation and scale-up of eleven different physical activity interventions. A thematic analysis was conducted to identify factors related to the implementation and scale-up of the included interventions. The data collection and analysis were guided by the Consolidated Framework for Implementation Research.

RESULTS

Thirty-eight participants took part in the interviews which identified factors related to 1) intervention planning and practical considerations; 2) organisational structures, staffing and resources related to delivery; 3) reflection, evaluation and updating of the intervention; and 4) practical consideration related to scale-up. Furthermore, participants referred to the ongoing commitment, engagement, and support needed throughout the implementation process.

CONCLUSIONS

Future research and practice needs to consider how different factors are experienced at different implementation stages and by the different stakeholder groups involved. The findings highlight multiple inter-related factors that influence the implementation and scale-up of physical activity interventions, but also identifies many strategies that can be utilised to aid future successes.

Factors associated with provision of physical activity in primary schools in Makindye Division in Kampala, Uganda: a cross-sectional study

BACKGROUND

Globally, school-going children spend most of their days at school, sitting in lessons and unable to achieve the daily WHO recommendations for Physical Activity (PA) of at least 60 minutes per day. Limited studies have assessed the opportunities schools provide for PA to help the children achieve their daily recommended PA. We determined the level of and the factors associated with PA offered in primary schools in Makindye Division in Kampala during the school term.

METHODS

This cross-sectional study was conducted in 36 selected government and private primary schools in Makindye Division, Kampala. PA was defined as the amount of time in minutes available for PA as per WHO recommendations - sufficient (60 minutes or more of PA) or insufficient (less than 60 minutes of PA) and assessed for any factors associated with provision of time for PA in schools. Data were collected by interview administered questionnaires and analysed descriptively. Factors associated with PA were assessed using a logistic regression model.

RESULTS

Of the 36 schools, 3 were government and 33 were private schools. The proportion of schools offering sufficient time for PA among Primary schools in the Makindye Division was (8/36) 22%. The average time for PA for all schools per week was 197 minutes (SD 70.7). Sufficient PA was associated with the provision of PE lessons after a break or after lunch (p-value 0.038). Sufficient PA was more likely in schools that offered volleyball (OR 8.69), had space in the school for PA (OR 13.27), provided athletics (OR 2.26) and whose fees were Ushs 700,000 (USD 187) or more (OR 1.30).

CONCLUSIONS

Only 22% of sampled schools offered sufficient time for PA among Primary schools in Kampala per WHO guidelines. Provision of sufficient time for PA was associated with PE scheduled either after break or lunch. Sufficient PA was more likely with schools that had space for PA, schools which offered volleyball and athletics, and whose fees were 700,000/= or more. Schools should consider scheduling PE lessons after break or after lunch to increase the likelihood of meeting the targeted time for PA. Primary schools need to be supported to establish facilities and to increase diversity in available activities to ensure children achieve their recommended PA.

Factors impacting implementation of nutrition and physical activity policies in rural schools

BACKGROUND

Rural Latino children have higher rates of obesity compared to non-Latino Whites. Schools are in a unique position to address rural childhood obesity through policies. While evidence exists on factors that promote or impede school-based physical activity (PA) and nutrition policies, only a fraction has been in rural communities. This study seeks to understand 1) the knowledge and perceptions of school nutrition and PA policies and 2) barriers and facilitators to their implementation among rural school stakeholders from Washington State.

METHODS

We conducted 20 semi-structured, in-depth interviews with school stakeholders (e.g., principals and school nutrition directors) from four K-12 school districts in the Lower Yakima Valley of Eastern Washington State. Thematic analysis was conducted using inductive, constant comparison approach to identify themes around knowledge and perceptions of policies and barriers and facilitators of policy implementation.

RESULTS

Three main themes were identified: perceptions and knowledge of school PA and nutrition policies, barriers to policy implementation, and facilitators of policy implementation. The majority of stakeholders were supportive of school-based policies promoting PA and a healthy diet, even when lacking a specific understanding of these policies. Four subthemes were identified as barriers to policy implementation: viewing PA as a low priority, misuse of recess time, funding constraints, and lack of strong leadership. Facilitators of implementation included strong leadership at the district level, creating healthy norms through school-community linkages and pooling community resources to improve nutrition and PA among children.

CONCLUSIONS

Schools provide a unique setting to promote healthy diet and PA behaviors among children and their families. Study findings show that while knowledge of specific nutrition and PA policies may vary, support for such policies were high among rural stakeholders. Study findings can inform policy development and support strategies for policy implementation in rural settings. Future studies may want to examine whether implementation of strategies addressing the barriers and enhancing facilitators lead to success in rural school settings.

Trend Impact Analysis (TIA) of community-based futures study for pediatric obesity in Iran

BACKGROUND

Childhood obesity has been regarded as one of the main healthcare challenges in the last century, leading to critical health problems and reduced life expectancy. Many factors can play a role in its development or prevention. Using the Trend Impact Analysis (TIA), this study aimed to conduct a community-based futures study for pediatric obesity in Iran.

METHODS

We obtained the prevalence of overweight and obesity from the database of the Ministry of Health and Medical Education. Moreover, we reviewed 21 documents, texts, and comments from three key stakeholders in Iran and prepared a list of key experts, who were stakeholders in the field of obesity prevention of childhood in different organizations. Then, we collected the expert opinions by Delphi method. Data analysis was performed using the Excel and R software.

RESULTS

Fourteen experts participated in the first stage and nine experts in the second stage. We identified two positive drivers, including the prevalence of coronavirus disease 2019 (COVID-19) and the widespread expansion of online educational programs. Meanwhile, we identified five negative drivers as follows: (1) controlling and limiting obesogenic environments in the community, school, and family; (2) running annual compulsory anthropometry programs for students of all educational levels in health centers; (3) integrating nutrition education interventions in the curricula of all educational levels; (4) taxation of unhealthy and fast foods; and (5) preparing safe and appropriate sports environments for children and adolescents (on the streets, schools, parks, and sports clubs). Without considering the drivers, the prevalence of overweight and obesity is predicted to reach 29.10% in 2031. However, it is expected that the negative drivers can increase the prevalence trend from 23.40% in 2018 to 19.57% in 2031, the positive drivers to 32.61%, and the combination of all drivers to 23.07%.

CONCLUSION

It seems that measures such as the effective communication of policy makers, basic evaluation of the programs and policies related to the prevention of childhood obesity, and localization of the programs of international organizations for the prevention of obesity can greatly control the prevalence of childhood obesity.

Mind the gap: Danish school heads' ability to implement a national physical activity school requirement

In 2014, the Danish government introduced a wide-ranging reform of primary and lower secondary education that applied to all public schools. A distinctive feature was that it became mandatory for schools to provide an average of 45 min of daily physical activity (PA). The capacity for change of local school heads and the schools overall are considered key to fulfilling such a policy-driven requirement. The aim of this study is therefore to explore local school heads' ability to implement the stated requirement of 45 min of daily PA within their local organizational capacity for change. Eleven semi-structured interviews were conducted across 11 schools. Respondents were school staff with management responsibilities (leading teachers with school management responsibilities, deputy heads and school heads). Results indicate that local school heads are central agents in converting the Danish school requirement of 45 min of daily PA into local action. This includes their ability to advance broad aims into concrete goals, secure supportive structures and organize the implementation strategy. Heads also need to support the staff in building sufficient knowledge capacity on how to arrange and incorporate PA into their daily practice, support the widespread dissemination of this knowledge across the school and reserve work hours for such activities. Assigning local PA ambassadors was particularly highlighted as important implementation support, as they can help build and disseminate knowledge while also broadcasting the school head's strategy and focus on integrating and upholding students' PA levels.

Investigating the direct and indirect effects of a school-based leadership program for primary school students: Rationale and study protocol for the 'Learning to Lead' cluster randomised controlled trial

BACKGROUND

Leadership is a valuable skill that can be taught in school, and which may have benefits within and beyond the classroom. Learning to Lead (L2L) is a student-led, primary school-based leadership program whereby older 'peer leaders' deliver a fundamental movement skills (FMS) program to younger 'peers' within their own school.

AIM

The aims of the study are to determine the efficacy of a peer-led FMS intervention on: (i) peer leaders' (aged 10 to 12 years) leadership effectiveness (primary outcome), leadership self-efficacy, well-being, and time on-task in the classroom; (ii) peers' (aged 8 to 10 years) physical activity levels, actual and perceived FMS competency, cardiorespiratory fitness, muscular power, and executive functioning; and (iii) teachers' (referred to as 'school champions') work-related stress and well-being.

METHOD

L2L will be evaluated using a two-arm parallel group cluster randomised controlled trial. Twenty schools located within a two-hour drive of the University of Newcastle, Australia will be recruited. We will recruit 80 students (40 peer leaders and 40 peers) from each school (N = 1,600). L2L will be implemented in three phases: Phase 1 -school champions' training via a professional learning workshop; Phase 2 -school champions' delivery of leadership lessons to the peer leaders; and Phase 3 -peer leaders' delivery of the FMS program to their younger peers. The FMS program, consisting of 12 x 30-minute lessons, will be delivered over the course of one school term (10 weeks). Study outcomes will be assessed at baseline (between mid-March to June, Terms 1 and 2), intervention end (mid-August to September, Term 3), and follow-up (November to mid-December, Term 4. This trial was prospectively registered on the Australian New Zealand Clinical Trials Registry (ANZCTR); registration number: ACTRN12621000376842.

Barriers and facilitators of childhood obesity prevention policies: A systematic review and meta-synthesis

Objectives

Childhood obesity is one of the worldwide considerable public health challenges and many factors can play a role in its management. Therefore, this article examined the facilitators and barriers of childhood obesity prevention (COP) policies.

Methods

This systematic review of qualitative studies was conducted via a search of the SCOPUS, PubMed, and Google Scholar databases between 1 January 2010 and 11 February 2022 and examined factors that influence the implementation of COP policies at a community approach.

Results

The parents' reluctance to engage in COP activities, lack of sufficient knowledge, and financial problems were the most reported barriers at the individual level. In addition, the beliefs about COP at the sociocultural level and limited funding and resources, time limitations in stakeholders at the implementation level, and lack of policy support at the structural level were the most frequently reported barriers. Further, effective communication between stakeholders and parents and school staff at the sociocultural level and flexibility of the intervention, delivery of healthy food programs in schools, low-cost and appropriate resources, and the availability of appropriate facilities are the most frequently reported facilitators in the structural level.

Conclusion

Individual, sociocultural, and structural level-related barriers and facilitators influence the implementation of COP policies. Most of the barriers and facilitators in this systematic review were related to the structural level.

Barriers and facilitators to the adoption of physical activity policies in elementary schools from the perspective of principals: An application of the consolidated framework for implementation research-A cross-sectional study

Background

Studies have shown that policies to promote physical activity in schools can have a positive impact on children's physical activity behavior. However, a large research gap exists as to what determinants may influence the adoption of such policies. Applying the Consolidated Framework for Implementation Research (CFIR), we investigated barriers and facilitators to the adoption of physical activity policies in elementary schools in Baden-Wuerttemberg, Germany, from the perspective of school principals.

Methods

A cross-sectional study was conducted between May and June 2021. School principals from elementary and special needs schools (n = 2,838) were invited to participate in the study. The online questionnaire used was developed based on the CFIR and included questions on school characteristics and constructs of the CFIR domains inner setting, characteristics of individuals, and process. Logistic regression analyses were performed to examine associations between policy adoption and school characteristics as well as CFIR determinants.

Results

In total, 121 schools (4%) participated in the survey, of which 49 (40.5%) reported having adopted a policy to promote physical activity. Positive associations with policy adoption were found for general willingness among teaching staff [odds ratio (OR): 5.37, 95% confidence interval (CI): 1.92-15.05], available resources (OR: 2.15, 95% CI: 1.18-3.91), access to knowledge and information (OR: 2.11, 95% CI: 1.09-4.09), and stakeholder engagement (OR: 3.47, 95% CI: 1.24-9.75).

Conclusions

This study provides a first insight into potential barriers and facilitators at the organizational level of schools that may be relevant to the adoption of physical activity policies, from the perspective of school principals. However, due to a low response rate, the results must be interpreted with caution. A strength of this study includes theoretical foundation through the use of the CFIR. The CFIR could be well-adapted to the school setting and provided valuable support for developing the questionnaire and interpreting the study results.

Barriers and enablers to the implementation of school-based obesity prevention strategies in Jeddah, KSA

Introduction

Despite schools' recognised role in mitigating childhood overweight, many schools fail to implement physical activity or nutrition strategies. The current study explored the enablers and barriers to implementing obesity prevention strategies in Jeddah, KSA.

Methods

This research is based on 14 semi-structured interviews with intermediate school principals and sports teachers to gain insight into their perception of barriers and enablers to implementing obesity prevention strategies. Themes were deductively generated from the data.

Results

Participants estimated the prevalence of overweight and obesity among their students to be between 3 and 15% with an increasing trend, particularly among female students. Participants identified five categories of barriers to implementation of obesity prevention intervention: curriculum; schools strategies promoting healthy weight; lack of resources; student’s lifstyle; and a lack of teachers in nutrition and sports. School regulations, staff and sufficient resources were the most frequently reported enablers. Participants also identified food services, awareness, and partnerships as barriers and enablers.

Conclusion

There is a need for better infrastructure and financial support for schools and professional development opportunities for teachers from the Saudi Ministry of Education. The Ministry also needs to support the development of multilevel health promotion strategies at school and home and reach out to the broader community.

Exploring the acceptability and feasibility of a whole school approach to physical activity in UK primary schools: a qualitative approach

Background

UK Children generally fail to meet physical activity (PA) recommendations. Whole school approaches (WSA) have the potential to impact large numbers of children due to their ubiquitous nature for school wide implementation, however there is limited knowledge regarding primary school PA WSA implementation in the UK. This study aimed to investigate the acceptability and feasibility of a PA WSA in the UK. 

Methods

Semi structured interviews explored research aims with participants. A qualitative description approach was adopted and data were analysed using thematic analysis to draw codes and themes from the data.

Results

Thirteen primary school senior leadership team (SLT) and Physical Education (PE) leads were interviewed. A PA WSA was found acceptable by all participants. Implementation, however, was questioned when other significant mechanisms were not in place. A PA WSA aided prioritisation and planning of PA provision, providing a holistic overview of all key areas of PE, school-sport and PA (PESSPA). Due to the high acceptability but dependent feasibility of a PA WSA, it is recommended that PA WSAs align with whole-school health policy and improvement plans to advance implementation. Future research, however, is needed to explore how this method is best implemented as additional interventions may also be required to promote the prioritisation of the PA agenda due to the importance of SLT backing for implementation being paramount, as results highlight.

Conclusions

PA WSAs aid awareness, understanding and planning of school wide PESSPA provision, however their implementation in complex. Having SLT support and an appropriately resourced PE lead maximised the impact and utility of a PA WSA.

The Use of Wearable Activity Trackers in Schools to Promote Child and Adolescent Physical Activity: A Descriptive Content Analysis of School Staff's Perspectives

BACKGROUND

The school environment is an ideal setting for promoting physical activity (PA). Wearable activity trackers (wearables) have previously been implemented, in research, as intervention tools within the school-environment. However, the large-scale use and acceptance of wearables, in schools, is unknown.

METHODS

This study distributed a cross-sectional survey to school staff to investigate the prevalence of child and adolescent wearable use in schools, including when and how they are used, and school staff's willingness to use them in the future (as implemented by school staff). This survey consisted of between 13 and 22 items, including closed-ended and open-ended questions. Closed-ended responses were displayed descriptively (wearable prevalence and characteristics), and open-ended qualitative responses were categorised using descriptive content analysis (how wearables are used).

RESULTS

1087 school staff provided valid responses. Of those, 896 (82.4%) had never used a wearable as a teaching or support tool for their students, and 120 (11%) currently used- and 71 (6.5%) had previously used- a wearable as a teaching or support tool for their students. When wearables were used, school staff implemented their use regularly and during physical education lessons or throughout the entire school day. Wearables were used to monitor or increase student's PA levels, or for student and staff educational purposes (e.g., academic learning, movement breaks). Most school staff were willing to use a wearable as a teaching or support tool to promote student's PA, and/or learning about PA, in the future.

CONCLUSIONS

This study is the first study to explore the widescale use and acceptance of children and adolescents using wearables in the school-setting. Findings may inform the development of future school-based interventions and public health initiatives for physical activity promotion, using wearables.

Comprehensive school health: teachers' perceptions and implementation of classroom physical activity breaks in US schools

Modifications to the social-ecological model, such as Whole School, Whole Community, Whole Child (WSCC) frameworks, have been utilized in comprehensive school health interventions. Classroom physical activity breaks are used when implementing whole-of-school approaches. However, the onus to implement classroom physical activity breaks is on school stakeholders. This study aimed to explore teacher and principal perceptions and implementation of physical activity breaks in elementary schools. Further, this study investigated how theoretical factors representative of the social-ecological model and their interactions affect teacher and principal perceptions and utilization of classroom physical activity breaks. Interviews were conducted to understand teacher and principal perceptions and implementation. A total of 12 classroom teachers and five principals participated in semi-structured interviews which were analyzed using constant comparison and deductive analysis to identify relationships and themes coded across the social-ecological and WSCC models. To ensure fidelity individuals that led the professional development (n = 2) were also interviewed. Three main themes emerged as part of the data analysis: (i) The Connection Between Intrapersonal Knowledge and Interpersonal Professional Development, (ii) Resources, Sharing Means Caring and (iii) The Policy Level Creates Time. Teachers and principals valued knowledge and resources and felt that policy facilitated implementation. Results suggest that classroom physical activity breaks are influenced by multiple factors across varied levels of the social-ecological model. Understanding this relationship can inform future professional development to increase the provision of classroom physical activity breaks among teachers.

The Feasibility and Acceptability of an Online CPD Programme to Enhance PE Teachers' Knowledge of Muscular Fitness Activity

Schools provide an opportunity to enhance muscular fitness of English youth during physical education (PE). Continued professional development (CPD) among teachers may improve muscular fitness activity delivery in schools. This study sought to assess the feasibility and acceptability of an online CPD programme to enhance PE teachers' knowledge of muscular fitness activity.

METHODS

Co-production of an online CPD platform was undertaken with five secondary school PE teachers. A quasi-experimental pre-post control group design for the CPD was adopted (CPD group n = 76, control n = 32). Upon CPD completion feedback was solicited for qualitative analysis.

RESULTS

Pre-and-post CPD knowledge quiz data were available from 65 participants (55.4% male). The median knowledge quiz change score was significantly higher in the CPD group than in the wait list control group (CPD score vs. control score; U =37, z = -5.96, p < 0.01). Three primary themes reflecting factors associated with the acceptability and feasibility were (1) practical application, (2) support and resources, and (3) knowledge and confidence.

CONCLUSIONS

Co-production of an online CPD programme can improve knowledge and affect practice. PE teachers that completed the CPD reported the online platform was beneficial to overcoming the limitations of face-to-face CPD such as time and financial constraints and suggested the content covered was beneficial and appropriate to their teaching. Future work is required to establish links between teachers' learning following CPD, the translation into PE practice and student MF outcomes.

Feasibility of a peer-led, after-school physical activity intervention for disadvantaged adolescent females during the COVID-19 pandemic: results from the Girls Active Project (GAP)

Introduction

There is a critical need for interventions that can be feasibly implemented and are effective in successfully engaging adolescent females in physical activity (PA). A theory-based, peer-led, after-school PA intervention, the Girls Active Project (GAP), was codesigned with adolescent females. This study aimed to assess the feasibility of implementing and evaluating the GAP programme.

Setting

One single-sex, female-only, designated disadvantaged postprimary school (students aged 12–18) in Dublin, Ireland.

Methods

Mixed methods were applied with multiple stakeholders over a 12-week trial (March to May 2021). A single-arm study design was used to examine intervention: reach, dose, fidelity, acceptability, compatibility and context. Feasibility of using proposed self-reported outcome measures (moderate-to-vigorous PA levels, self-rated health, life satisfaction, PA self-efficacy and PA enjoyment) was also explored. Due to school closure resulting from the COVID-19 pandemic, the intervention was delivered both online and in person in the school setting.

Results

Eight exercise classes were peer delivered by project leaders (n = 6, students aged 15–17) to intervention recipients (students aged 13-14). Recruitment was low (n = 8, 10% of eligible students, mean age: 13.3 SD: 0.46), yet retention was high (n = 7/8, 88%). Attendance rates were satisfactory (68%), and the intervention was implemented with high fidelity (87%). Data completion rates suggested proposed self-reported outcome measures were deemed appropriate (≥ 95%), except for weight (50%) and height data (80%). Despite COVID-19 hindering intervention implementation, both quantitative and qualitative data suggested that stakeholders were satisfied and perceived the in-person delivered intervention to be compatible with the school setting. Recommended refinements included extending class duration, introducing different rewards, and boosting programme awareness.

Conclusions

Further thought must be given on how to increase recruitment. Overall, the in-person delivered after-school PA programme was well-received by stakeholders and shows promise as an intervention that can be feasibly implemented and evaluated. Suggested improvements to the GAP intervention programme are recommended, before continuing to a more robust evaluation.

Strategies for enhancing the implementation of school-based policies or practices targeting diet, physical activity, obesity, tobacco or alcohol use

BACKGROUND

Several school-based interventions are effective in improving child diet and physical activity, and preventing excessive weight gain, and tobacco or harmful alcohol use. However, schools are frequently unsuccessful in implementing such evidence-based interventions.

OBJECTIVES

1. To evaluate the benefits and harms of strategies aiming to improve school implementation of interventions to address student diet, physical activity, tobacco or alcohol use, and obesity. 2. To evaluate the benefits and harms of strategies to improve intervention implementation on measures of student diet, physical activity, obesity, tobacco use or alcohol use; describe their cost or cost-effectiveness; and any harms of strategies on schools, school staff or students.

SEARCH METHODS

We used standard, extensive Cochrane search methods. The latest search was between 1 September 2016 and 30 April 2021 to identify any relevant trials published since the last published review.

SELECTION CRITERIA

We defined 'Implementation' as the use of strategies to adopt and integrate evidence-based health interventions and to change practice patterns within specific settings. We included any trial (randomised controlled trial (RCT) or non-randomised controlled trial (non-RCT)) conducted at any scale, with a parallel control group that compared a strategy to implement policies or practices to address diet, physical activity, overweight or obesity, tobacco or alcohol use by students to 'no intervention', 'usual' practice or a different implementation strategy.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methods. Given the large number of outcomes reported, we selected and included the effects of a single outcome measure for each trial for the primary (implementation) and secondary (student health behaviour and obesity) outcomes using a decision hierarchy. Where possible, we calculated standardised mean differences (SMDs) to account for variable outcome measures with 95% confidence intervals (CI). For RCTs, we conducted meta-analyses of primary and secondary outcomes using a random-effects model, or in instances where there were between two and five studies, a fixed-effect model. The synthesis of the effects for non-randomised studies followed the 'Synthesis without meta-analysis' (SWiM) guidelines.

MAIN RESULTS

We included an additional 11 trials in this update bringing the total number of included studies in the review to 38. Of these, 22 were conducted in the USA. Twenty-six studies used RCT designs. Seventeen trials tested strategies to implement healthy eating, 12 physical activity and six a combination of risk factors. Just one trial sought to increase the implementation of interventions to delay initiation or reduce the consumption of alcohol. All trials used multiple implementation strategies, the most common being educational materials, educational outreach and educational meetings. The overall certainty of evidence was low and ranged from very low to moderate for secondary review outcomes. Pooled analyses of RCTs found, relative to a control, the use of implementation strategies may result in a large increase in the implementation of interventions in schools (SMD 1.04, 95% CI 0.74 to 1.34; 22 RCTs, 1917 participants; low-certainty evidence). For secondary outcomes we found, relative to control, the use of implementation strategies to support intervention implementation may result in a slight improvement on measures of student diet (SMD 0.08, 95% CI 0.02 to 0.15; 11 RCTs, 16,649 participants; low-certainty evidence) and physical activity (SMD 0.09, 95% CI -0.02 to 0.19; 9 RCTs, 16,389 participants; low-certainty evidence). The effects on obesity probably suggest little to no difference (SMD -0.02, 95% CI -0.05 to 0.02; 8 RCTs, 18,618 participants; moderate-certainty evidence). The effects on tobacco use are very uncertain (SMD -0.03, 95% CIs -0.23 to 0.18; 3 RCTs, 3635 participants; very low-certainty evidence). One RCT assessed measures of student alcohol use and found strategies to support implementation may result in a slight increase in use (odds ratio 1.10, 95% CI 0.77 to 1.56; P = 0.60; 2105 participants). Few trials reported the economic evaluations of implementation strategies, the methods of which were heterogeneous and evidence graded as very uncertain. A lack of consistent terminology describing implementation strategies was an important limitation of the review.

AUTHORS' CONCLUSIONS

The use of implementation strategies may result in large increases in implementation of interventions, and slight improvements in measures of student diet, and physical activity. Further research is required to assess the impact of implementation strategies on such behavioural- and obesity-related outcomes, including on measures of alcohol use, where the findings of one trial suggest it may slightly increase student risk. Given the low certainty of the available evidence for most measures further research is required to guide efforts to facilitate the translation of evidence into practice in this setting.

Location-specific psychosocial and environmental correlates of physical activity and sedentary time in young adolescents: preliminary evidence for location-specific approaches from a cross-sectional observational study

BACKGROUND

A better understanding of the extent to which psychosocial and environmental correlates of physical activity are specific to locations would inform intervention optimization.

PURPOSE

To investigate cross-sectional associations of location-general and location-specific variables with physical activity and sedentary time in three common locations adolescents spend time.

METHODS

Adolescents (N = 472,Mage = 14.1,SD = 1.5) wore an accelerometer and global positioning systems (GPS) tracker and self-reported on psychosocial (e.g., self-efficacy) and environmental (e.g., equipment) factors relevant to physical activity and sedentary time. We categorized each survey item based on whether it was specific to a location to generate psychosocial and environmental indices that were location-general or specific to either school, non-school, or home location. Physical activity (MVPA) and sedentary time were based on time/location match to home, school, or all "other" locations. Mixed-effects models investigated the relation of each index with location-specific activity.

RESULTS

The location-general and non-school physical activity psychosocial indices were related to greater MVPA at school and "other" locations. The school physical activity environment index was related to greater MVPA and less sedentary time at school. The home activity environment index was related to greater MVPA at home. The non-school sedentary psychosocial index was related to less sedentary time at home. Interactions among indices revealed adolescents with low support on one index benefited (i.e., exhibited more optimal behavior) from high support on another index (e.g., higher scores on the location-general PA psychosocial index moderated lower scores on the home PA environment index). Concurrent high support on two indices did not provide additional benefit.

CONCLUSIONS

No psychosocial or environment indices, including location-general indices, were related to activity in all locations. Most of the location-specific indices were associated with activity in the matching location(s). These findings provide preliminary evidence that psychosocial and environmental correlates of activity are location specific. Future studies should further develop location-specific measures and evaluate these constructs and whether interventions may be optimized by targeting location-specific psychosocial and environmental variables across multiple locations.

Optimising a multi-strategy implementation intervention to improve the delivery of a school physical activity policy at scale: findings from a randomised noninferiority trial

Background

To maximise their potential health benefits, school-based physical activity policies need to be implemented at scale. This paper describes the third in a sequence of trials that sought to optimise an effective strategy (PACE) to assist schools’ implementation of a physical activity policy. Specifically, it aimed to determine the probability that a multi-strategy intervention adapted to reduce in-person contact (Adapted PACE) was “as good as” the original intervention (PACE) in increasing the weekly minutes of structured physical activity implemented by classroom teachers.

Methods

A noninferiority cluster randomised controlled trial was undertaken with 48 primary schools in New South Wales, Australia. Schools were randomised to receive PACE or a model with adaptations made to the delivery modes (Adapted PACE). Teachers’ scheduled minutes of weekly physical activity was assessed at baseline (Oct 2018-Feb 2019) and 12-month follow-up (Oct-Dec 2019). The noninferiority margin was set at − 16.4 minutes based on previous data and decision panel consensus. A linear mixed model analysed within a Bayesian framework was used to explore noninferiority between the two PACE models. A cost minimisation analysis was conducted from the health service provider perspective, using the Australian dollar (AUD).

Results

The posterior estimate for the between group difference at follow-up was − 2.3 minutes (95% credible interval = − 18.02, 14.45 minutes). There was an estimated 96% probability of Adapted PACE being considered noninferior (only 4% of the posterior samples crossed the noninferiority margin of − 16.4 minutes). That is, the minutes of physical activity implemented by teachers at Adapted PACE schools was not meaningfully less than the minutes of physical activity implemented by teachers at PACE schools. The mean total cost was AUD$25,375 (95% uncertainty interval = $21,499, $29,106) for PACE and AUD$16,421 (95% uncertainty interval = $13,974, $19,656) for Adapted PACE; an estimated reduction of AUD$373 (95% uncertainty interval = $173, $560) per school.

Conclusions

It is highly probable that Adapted PACE is noninferior to the original model. It is a cost-efficient alternative also likely to be a more suitable approach to supporting large scale implementation of school physical activity policies.

Effects of In-Classroom Physical Activity Breaks on Children's Academic Performance, Cognition, Health Behaviours and Health Outcomes: A Systematic Review and Meta-Analysis of Randomised Controlled Trials

In-Classroom physical activity breaks (IcPAB) are a promising way to promote children’s health behaviors, while contributing to the development of their academic and cognitive ability and health outcomes. Yet the effect of the activity breaks, which are exclusive to classroom settings, are still mixed and unclear. Hence, this review was conducted to identify the characteristics and the effects of IcPAB among primary school children. The review protocol was registered on PROSPERO (CRD42021234192). Following the Cochrane guidelines, PubMed, PsycINFO (ProQuest), MEDLINE (EBSCOhost), Embase/Ovid, SportDISCUS (EBSCOhost), Web of Science, Scopus and Academic Search Premier (EBSCOhost) databases were searched to collect data on randomised control trials without a time restriction. The final database search was conducted on the 8 November 2021. Random effects models were used to calculate the effect sizes. The systematic review identified ten eligible studies, nine of which were also included in the meta-analysis. Few studies used the theoretical frameworks and process evaluations. IcPAB showed mixed effectiveness on academic outcomes: i.e., IcPAB had effects on spelling performance (p < 0.05) and foreign language learning (p < 0.01) but not on mathematics and reading performance. Health behaviors such as moderate-to-vigorous physical activity levels were improved (p < 0.01), but IcPAB did not have an impact on cognition outcomes and health outcomes. Given these mixed results, further research is needed underpinned by strong methodological quality, theoretical underpinnings and reliable process evaluation methods.
