Preliminary assessment of a school-based healthy lifestyle intervention among rural elementary school children

School-based obesity prevention programs in rural communities: a scoping review

OBJECTIVE

The objective of this review was to examine existing literature and conceptually map the evidence for school-based obesity prevention programs implemented in rural communities, as well as identify current gaps in the literature.

INTRODUCTION

Pediatric obesity is a significant public health condition worldwide. Rural residency places children at increased risk of obesity. Schools have been identified as an avenue for obesity prevention in rural communities.

INCLUSION CRITERIA

We considered citations focused on children (5 to 18 years of age) enrolled in a rural educational setting. We included obesity prevention programs delivered in rural schools that focused on nutrition or dietary changes, physical activity or exercise, decreasing screen time, or combined nutrition and physical activity that aimed to prevent childhood obesity. We included all quantitative, qualitative, and mixed methods research designs, as well as text and opinion data.

METHODS

A search was conducted of published and unpublished studies in English from 1990 through April 2020 using PubMed, CINAHL Complete, ERIC, Embase, Scopus, Academic Search Premier, Cochrane Register of Controlled Trials, and ClinicalTrials.gov. Gray literature was also searched. After title and abstract review, potentially relevant citations were retrieved in full text. The full texts were assessed in detail against the inclusion criteria by 2 independent reviewers. Included citations were reviewed and data extracted by 2 independent reviewers and captured on a spreadsheet targeting the review objectives.

RESULTS

Of the 105 studies selected for full-text review, 72 (68.6%) were included in the final study. Most of the studies (n = 50) were published between 2010 and 2019 and were conducted in the United States (n = 57). Most studies included children in rural elementary or middle schools (n = 57) and targeted obesity prevention (n = 67). Teachers implemented the programs in half of the studies (n = 36). Most studies included a combination of physical activity and nutrition components (n = 43). Other studies focused solely on nutrition (n = 9) or physical activity (n = 9), targeted obesity prevention policies (n = 9), or other components (n = 8). Programs ranged in length from weeks to years. Overall, weight-related, physical activity-specific, and nutrition-specific outcomes were most commonly examined in the included citations.

CONCLUSIONS

Obesity prevention programs that focused on a combination of physical activity and nutrition were the most common. Multiple outcomes were examined, but most programs included weight-specific and health behavior-specific outcomes. The length and intensity of rural school-based obesity prevention programs varied. More research examining scientific rigor and specific outcomes of rural school-based obesity prevention programs is needed.

Effect of a Three-Month HOPSports Brain Breaks® Intervention Program on the Physical Fitness Levels of Grade 6-Learners in South Africa

Despite the numerous health benefits of being physically active, children are not active enough. Various researchers have indicated that intervention programs improve physical fitness levels. Still, only a few have focused on improving physical fitness levels by incorporating technology. HOPSports Brain Breaks® are designed and presented as physical activity solutions with online videos requiring the participants to imitate the movements. These videos are 2-5-min classroom activity breaks. This study determined the effect of a three-month HOPSports Brain Breaks® intervention program on the physical fitness levels of Grade 6-learners. Physical fitness was measured with the EUROFIT test battery. The experimental group consisted of 79 children (26 boys and 47 girls) and the control group of 47 children (16 boys and 33 girls). The mean age for the entire group was 11.92 (±0.36) years. The results indicated that there was a statistically (p ≤ 0.05) and practically (d ≥ 0.20) significant difference between the experimental and control group for percentage body fat; stork balance; plate tapping; sit-and-reach; standing jump; sit-ups; and 10 × 5 m shuttle run and 20 m shuttle run between the pre-and post-test. Therefore, considering the results mentioned above, the HOPSports Brain Breaks® intervention program can indeed contribute to the improvement of physical fitness, and motor skills of children. Therefore, future studies should be conducted to determine the effect of HOPSports Brain Breaks® between genders as well as what impact it will have on academic performance.

Family-focused obesity prevention program implementation in urban versus rural communities: a case study

Purpose

Despite public health efforts to reduce childhood obesity, there remains an unequal distribution of obesity among rural and urban children, with higher rates in rural areas. However, few studies have compared differences in program delivery. This paper aims to describe differences between an urban and rural program delivery of a family-focused, community-based intervention program to prevent and reduce obesity among children.

Methods

This paper uses a case study format to provide a descriptive analysis of similar obesity prevention programs, designed by the same research team, implemented in Minnesota in different settings (i.e., an urban and rural setting) with significant community engagement in the adaptation process. The rural NU-HOME program is compared to HOME-Plus, an urban family-based obesity prevention program for school-aged children.

Results

Community engagement in the adaptation process of an urban program to a rural program confirmed some anticipated program content and delivery similarities while identifying key differences that were necessary for adaptation related to engagement with the community, recruitment and data collection, and intervention delivery.

Discussion

When adapting research-tested programs from urban to rural areas, it is important to identify the modifiable behavioral, social, and environmental factors associated with obesity to ensure the content of effective childhood obesity prevention programs is relevant. Customizing a program to meet the needs of the community may increase reach, engagement, and sustainability. In addition, long-term dissemination of a tailored program may significantly reduce childhood obesity in rural communities and be implemented in other rural settings nationally.

The evidence for the impact of policy on physical activity outcomes within the school setting: A systematic review

BACKGROUND

Despite the well-established health benefits of physical activity (PA) for young people (aged 4-19 years), most do not meet PA guidelines. Policies that support PA in schools may be promising, but their impact on PA behavior is poorly understood. The aim of this systematic review was to ascertain the level and type of evidence reported in the international scientific literature for policies within the school setting that contribute directly or indirectly to increasing PA.

METHODS

This systematic review is compliant with Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines. Six databases were searched using key concepts of policy, school, evaluation, and PA. Following title and abstract screening of 2323 studies, 25 progressed to data synthesis. Methodological quality was assessed using standardized tools, and the strength of the evidence of policy impact was described based on pre-determined codes: positive, negative, inconclusive, or untested statistically.

RESULTS

Evidence emerged for 9 policy areas that had a direct or indirect effect on PA within the school setting. These were whole school PA policy, physical education, sport/extracurricular PA, classroom-based PA, active breaks/recess, physical environment, shared use agreements, active school transport, and surveillance. The bulk of the evidence was significantly positive (54%), 27% was inconclusive, 9% was significantly negative, and 11% was untested (due to rounding, some numbers add to 99% or 101%). Frequency of evidence was highest in the primary setting (41%), 34% in the secondary setting, and 24% in primary/secondary combined school settings. By policy area, frequency of evidence was highest for sport/extracurricular PA (35%), 17% for physical education, and 12% for whole school PA policy, with evidence for shared use agreements between schools and local communities rarely reported (2%). Comparing relative strength of evidence, the evidence for shared use agreements, though sparse, was 100% positive, while 60% of the evidence for whole school PA policy, 59% of the evidence for sport/extracurricular PA, 57% of the evidence for physical education, 50% of the evidence for PA in classroom, and 50% of the evidence for active breaks/recess were positive.

CONCLUSION

The current evidence base supports the effectiveness of PA policy actions within the school setting but cautions against a "one-size-fits-all" approach and emphasizes the need to examine policy implementation to maximize translation into practice. Greater clarity regarding terminology, measurement, and methods for evaluation of policy interventions is needed.

Rapid Realist Review of School-Based Physical Activity Interventions in 7- to 11-Year-Old Children

Meta-analysis of physical activity interventions in school settings have revealed low efficacy and that there is a need to explore implementation fidelity. The aim of this rapid realist review was to determine, what physical activity interventions in school settings for children aged 7- to 11-years-old works, for whom, and in what circumstances. The realist synthesis was conducted following RAMESES guidelines. Relevant studies were identified following a systematic search process and data from 28 studies was extracted for evidence to form context-mechanism-outcome configurations that were clustered and refined. Using the five-level socioecological model, the program theories were classified into the levels of intrapersonal (child), interpersonal (teachers), institutional (program content, school administration, and school environment), community (home and neighborhood), and policy. The school level led to most context-mechanism-outcome configurations related to school leadership and policy, workforce structure, program characteristics, and school environment. At each level, we identified features of interventions, alongside implementation considerations that might work to promote efficacy and sustainability. The need to recognize the school environment as part of a complex system with multi-level interaction and influences was a key finding. In line with realist philosophy, the researchers encouraged primary research to confirm, refute, and refine the program theories presented.

Universal childhood obesity prevention in a rural community: Study design, methods and baseline participant characteristics of the NU-HOME randomized controlled trial

Childhood obesity is a major health concern in the United States (US) and those living in rural communities are at higher risk than their urban counterparts. Few prevention trials have engaged whole families of school-age children in community settings, and none to date have promoted family meals, family activity and healthful home environments in rural settings through a rigorous, randomized controlled trial (RCT). The New Ulm at HOME (NU-HOME) study recruited 114 parent/child dyads in a two-arm (intervention versus wait-list control) RCT to test the efficacy of a family meals-focused program aimed to prevent excess weight gain among 7-10 year-old children in rural Minnesota. The NU-HOME program was adapted from a previously tested program for urban families through a unique community collaboration. The program included 7 monthly in-person sessions for all family members. Parents also participated in 4 motivational goal-setting phone calls. The primary outcome measures were age- and sex-adjusted child body mass index (BMI) z-score, percent body fat, and incidence of overweight and obesity post-intervention. Secondary outcomes included quality of food and beverage availability in the home; family meals and snacks; children's dietary intake quality (e.g., Healthy Eating Index (HEI)-2015, fruits and vegetables, sugar-sweetened beverages, snacks); and children's screen time and weekly minutes of moderate-to-vigorous physical activity, total physical activity, and sedentary behavior. The NU-HOME RCT was a collaborative effort of academic and health system researchers, interventionists and community leaders that aimed to prevent childhood obesity in rural communities through engagement of the whole family in an interactive intervention.

A Systematic Review of Community Engagement Outcomes Research in School-Based Health Interventions

BACKGROUND

Involving communities in school health has been purported as a practice integral to supporting a Whole School, Whole Community, Whole Child (WSCC) approach. Although community collaboration is often included in school-based health initiatives, there is little research considering methods for increasing community engagement. The purpose of this study was to identify effective school-based health interventions documenting changes in community engagement.

METHODS

Academic experts and school stakeholders guided procedures for a systematic review of studies published from 1987-2017 and gray literature (ie, best practice documents; policy documents, etc.) on comprehensive school health interventions including community engagement as a targeted outcome.

RESULTS

The search identified 9 studies addressing community as an outcome of school-based health interventions; types of partnership mechanisms and partners' roles were classified.

CONCLUSIONS

Although involving communities is a WSCC component and commonly recommended as a strategy fundamental to school health, there is little empirical research examining effective strategies for engaging communities and engagement is often not measured as part of intervention studies. Further measurement and research in engaging communities in school health is warranted.

A mixed-studies systematic review and meta-analysis of school-based interventions to promote physical activity and/or reduce sedentary time in children

PURPOSE

The aim of this mixed-studies systematic review was to ascertain the effectiveness of school-based interventions in increasing physical activity (PA) and/or reducing sedentary time (ST) in children aged 5-11 years, as well as to explore their effectiveness in relation to categories of the theory of expanded, extended, and enhanced opportunity (TEO).

METHODS

Adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, 5 databases were searched using predefined search terms. Following title and abstract screening of 1115 records, the removal of duplicates (n = 584) and articles that did not meet the inclusion criteria agreed to a priori (n = 419) resulted in 112 records that were full-text screened. Two independent reviewers subsequently used the mixed-methods appraisal tool to assess the methodological quality of 57 full-text studies that met the inclusion criteria after full-text screening. The interventions were summarised using the TIDierR checklist and TEO. The strength of evidence was determined using a 5-level rating system utilising a published decision tree.

RESULTS

Overall evidence ratings for interventions implemented within school settings were: no evidence of effects on moderate-to-vigorous physical activity (MVPA) and inconclusive evidence of effects on sedentary time. In relation to the TEO, expansion of PA appeared to be the most promising intervention type for MVPA, with moderate evidence of effect, whereas extension and enhancement of PA opportunity demonstrated no evidence of effect. A critical issue of possible compensatory behavior was identified by analysis of intervention effect in relation to PA measurement duration; when studies measured changes in PA during the actual intervention, there was moderate evidence of effect, whereas those that measured changes in PA during the school day presented inconclusive evidence of effect, and those that measured changes in PA over a whole day yielded no evidence of effect. Two meta-analyses of those studies using a whole-day accelerometer measure for MVPA or ST showed a significant but moderate effect for MVPA (effect size = 0.51; 95% confidence interval (CI): 0.02-0.99) and a large but nonsignificant effect for ST (effect size = 1.15; 95%CI: -1.03 to 3.33); both meta-analyses demonstrated low precision, considerable inconsistency, and high heterogeneity.

CONCLUSION

The findings have important implications for future intervention research in terms of intervention design, implementation, and evaluation.

Impact of a Georgia elementary school-based intervention on physical activity opportunities: A quasi-experimental study

OBJECTIVES

To assess the impact of Power Up for 30, a flexible, Comprehensive School Physical Activity Program-based state-wide elementary school initiative, on school physical activity opportunities (physical education, recess, in-class physical activity, before-school physical activity, and after-school physical activity) one year after Power Up for 30 training.

DESIGN

Quasi-experimental.

METHODS

In 2013, all 1333 public Georgia elementary schools were invited to complete the School Physical Activity Survey which assessed school physical activity opportunities. Upon survey completion, schools were invited to attend training. Of the 719 (54%) schools meeting survey response criteria, 300 schools attended training by 9/2014 and 419 schools did not. Between 3/2015-5/2015, 79 trained and 80 untrained schools were randomly selected to receive a follow-up survey assessing the frequency and duration of physical activity opportunities. Analyses, adjusted for baseline physical activity opportunities and school characteristics, compared weekly minutes of physical activity opportunities at follow-up between trained and untrained schools.

RESULTS

In adjusted analyses at follow-up, trained schools provided 36 more minutes of weekly physical activity opportunities than untrained schools (99% confidence interval: 16-56), particularly during recess (mean difference: 8min per week; 99% confidence interval: 0-17), during in-class breaks (mean difference: 11min per week, 99% confidence interval: 3-20), and before school (mean difference: 8min per week, 99% confidence interval: 4-12).

CONCLUSIONS

Flexible, multi-component interventions like Power Up for 30 increase physical activity opportunities. If future studies identify that school physical activity opportunities positively impact student physical activity, this model may be a feasible strategy for broad-scale implementation.

Implementing and Evaluating Environmental and Policy Interventions for Promoting Physical Activity in Rural Schools

BACKGROUND

Schools are an important setting for improving behaviors associated with obesity, including physical activity. However, within schools there is often a tension between spending time on activities promoting academic achievement and those promoting physical activity.

METHODS

A community-based intervention provided administrators and teachers with a training on evidence-based public health and then collaborated with them to identify and implement environmental (walking track) and local school policy interventions (brain breaks). The evaluation included conducting in-depth interviews and SOPLAY observations to assess the facilitators and barriers and impact of the dissemination of environmental and policy changes.

RESULTS

Individual, organizational, intervention, and contextual factors influenced dissemination. Teachers reported that brain breaks increased student focus and engagement with classroom material and decreased student behavioral problems. Students decreased sedentary behavior and increased vigorous behavior. Of the 4 schools, 2 increased walking.

CONCLUSIONS

Active dissemination of environmental and policy interventions by engaging school administrators and teachers in planning and implementation shows potential for increasing physical activity in rural school settings.

USDA Fresh Fruit and Vegetable Program Is More Effective in Town and Rural Schools Than Those in More Populated Communities

BACKGROUND

We attempted to determine effects of the United States Department of Agriculture (USDA) Fresh Fruit and Vegetable Program (FFVP) on variety and frequency of fruit and vegetable intake by students in schools from different locales.

METHODS

Data were derived from the 2011-2012 Indiana FFVP Student Survey completed by 4229 fourth-sixth graders. Effects were studied within 2 groups, 39 city and suburb schools, and 12 town and rural schools. Differences in students' responses over time to 2 items measuring variety and 10 items measuring fruit and vegetable intake frequency were determined with multilevel regression models.

RESULTS

Town and rural students were 1.2 times more likely to eat different kinds of fruit (p = .04) and vegetables (p = .01) daily, and increased fruit (+1.0 time/day; p < .01) and vegetable intake frequency (+0.5 times/day; p = .03). City and suburb students increased fruit intake frequency (∼0.8 times/day; p < .01) but not vegetable intake frequency or daily variety (p > .05).

CONCLUSIONS

FFVP improved fruit and vegetable eating behaviors in the "town and rural" group, but was only partially effective in the "city and suburb" group. Strategies to implement FFVP may need to differ depending on school locale.

Physical Activity-Related Policy and Environmental Strategies to Prevent Obesity in Rural Communities: A Systematic Review of the Literature, 2002-2013

INTRODUCTION

Health disparities exist between rural and urban residents; in particular, rural residents have higher rates of chronic diseases and obesity. Evidence supports the effectiveness of policy and environmental strategies to prevent obesity and promote health equity. In 2009, the Centers for Disease Control and Prevention recommended 24 policy and environmental strategies for use by local communities: the Common Community Measures for Obesity Prevention (COCOMO); 12 strategies focus on physical activity. This review was conducted to synthesize evidence on the implementation, relevance, and effectiveness of physical activity-related policy and environmental strategies for obesity prevention in rural communities.

METHODS

A literature search was conducted in PubMed, PsycINFO, Web of Science, CINHAL, and PAIS databases for articles published from 2002 through May 2013 that reported findings from physical activity-related policy or environmental interventions conducted in the United States or Canada. Each article was extracted independently by 2 researchers.

RESULTS

Of 2,002 articles, 30 articles representing 26 distinct studies met inclusion criteria. Schools were the most common setting (n = 18 studies). COCOMO strategies were applied in rural communities in 22 studies; the 2 most common COCOMO strategies were "enhance infrastructure supporting walking" (n = 11) and "increase opportunities for extracurricular physical activity" (n = 9). Most studies (n = 21) applied at least one of 8 non-COCOMO strategies; the most common was increasing physical activity opportunities at school outside of physical education (n = 8). Only 14 studies measured or reported physical activity outcomes (10 studies solely used self-report); 10 reported positive changes.

CONCLUSION

Seven of the 12 COCOMO physical activity-related strategies were successfully implemented in 2 or more studies, suggesting that these 7 strategies are relevant in rural communities and the other 5 might be less applicable in rural communities. Further research using robust study designs and measurement is needed to better ascertain implementation success and effectiveness of COCOMO and non-COCOMO strategies in rural communities.

Measuring Physical Activity of Elementary School Children With Unsealed Pedometers: Compliance, Reliability, and Reactivity

BACKGROUND AND PURPOSE

Evidence of compliance, reliability, and reactivity of using pedometers in children remains inconsistent. This study aimed to examine these aspects of unsealed pedometers.

METHODS

There were 133 children who wore pedometers for 7 days. A subsample of 50 children completed surveys measuring self-efficacy, enjoyment, parental influence, and environment on Day 1 and 8. Investigator presence and incentives were used to increase compliance.

RESULTS

About 87% of children returned pedometers, with 62% wearing pedometers for 4 days or longer. The intraclass correlation coefficients ranged from .70 to .87, with ICC for 4-day pedometer steps exceeding .80. Wearing pedometers did not change pedometer steps nor alter children's perceptions of self-efficacy, enjoyment, parental influence, and environment significantly.

CONCLUSIONS

Children were compliant wearing pedometers, and there was no reactivity from wearing them.

Results of a 3-year, nutrition and physical activity intervention for children in rural, low-socioeconomic status elementary schools

Improving children's nutrition and physical activity have become priorities in the United States. This quasi-experimental study evaluated the longitudinal effects of a 3-year, school-based, health promotion intervention (i.e. nutrition and physical education, classroom physical activity, professional development and health promotion for teachers and families, and strengthening wellness policies and family/community partnerships) on children's health behaviors in four, rural, low-socioeconomic status elementary schools. A total of 999 kindergarten to third-grade children participated in data collection consisting of 4-day pedometer tracking and previous-day fruits and vegetables consumption recall from baseline in January, 2011 through 12 follow-up assessments ending May, 2013. The mixed-effects regression models showed that children's nutrition and physical activity behaviors significantly improved over the 3-year intervention. The percentages of children who met the nutrition recommendation increased from 11 to 23% for girls and 12 to 23% for boys, while the percent who met the physical activity recommendation increased from 1 to 16% for girls and 3 to 7% for boys. Further, children's age and their school impacted certain intervention effects. This school-based intervention could be disseminated to promote healthy behaviors among rural disadvantaged children. Engaging parents and community partnerships is recommended to expand the traditional, children-focused education interventions.

Self-management training for Chinese obese children at risk for metabolic syndrome: Effectiveness and implications for school health

This article reviews the results of a school-based self-management intervention for Chinese obese children at risk for metabolic syndrome. Twenty-eight Chinese obese children ( M age = 10 years) and their parents participated in the study. Metabolic syndrome risk factors were measured pre- and post-intervention. The risk factors included Body Mass Index, waist circumstance, systolic blood pressure, diastolic blood pressure, triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, High-sensitivity C-reactive Protein, fasting plasma glucose, and fasting blood insulin. After 6 months of school-based self-management intervention, all risk factors with the exception of triglycerides and fasting plasma glucose changed significantly in the healthful direction ( p < 0.01). This pilot study offers promising implications for school interventions that are delivered by school-based practitioners collaborating with parents, teachers, and children. An individualized program based on a self-care and -management framework may have utility as a relatively cost-effective, school-based intervention to improve children’s health.
