Socioecological factors potentially associated with participation in physical activity and sport: A longitudinal study of adolescent girls

The importance of family support to engage and retain girls in male dominated action sports. A qualitative study of young people's perspectives

ISSUE ADDRESSED

Social support is positively correlated with physical activity (PA), especially amongst girls, but is underexplored in male-dominated action sports (e.g., mountain biking, skateboarding and surfing). This study explored family level social support needs and experiences of girls and boys in three action sports.

METHOD

Aspiring, current or former Australian adolescent (12-18 years; girls n = 25; boys n = 17) mountain bikers, skateboarders and/or surfers were individually interviewed (telephone/Skype) in 2018/2020. A socio-ecological framework guided the semi-structured interview schedule. Audio-recordings were transcribed verbatim and data analysed thematically using a constant comparative approach.

RESULTS

Family level social support was highly influential in young people's participation in action sports, with its absence a common reason for no or discontinued engagement amongst girls. Parents and siblings were the main social support providers with extended family (e.g., grandparents, aunts/uncles, cousins) also notable. Participation (current/past/co-) was the main social support type followed by emotional (e.g., encouragement), instrumental (e.g., transport, equipment/funding) and informational (e.g., coaching) support. Girls were inspired/encouraged by brothers but boys were not inspired/encouraged by sisters; boys and girls co-participated with both parents but co-participating and being inspired by fathers was most common, especially amongst girls; fathers were more commonly the main transport provider if they co-participated with their child; fathers mostly provided initial coaching; only boys were taught equipment maintenance by parents.

CONCLUSIONS AND SO WHAT

Sport-related organisations/groups have numerous opportunities to improve girls' representation in action sports by fostering family level social support through various means. Intervention strategies should be tailored to account for gendered participation differences.

Long-term recreational exercise patterns in adolescents and young adults: Trajectory predictors and associations with health, mental-health, and educational outcomes

Individual and societal factors influencing the formation of long-term recreational exercise habits during the transition from adolescence to young adulthood are not well explored. Using data from the Longitudinal Survey of Australian Youth (LSAY), a population-representative cohort study of Young People followed from age 15 to 25, we aimed to (1) model longitudinal recreational exercise trajectories from age 16 to 24, (2) examine predictors at age 15 of entering these trajectories, and (3) explore the association between the trajectories and health, mental health and educational achievement outcomes measured at the final study wave (age 25). Self-reported recreational exercise frequency data from 9353 LSAY participants were analysed using group-based trajectory modelling. We modelled the evolution of two patterns of recreational exercise behaviour: daily exercise, as per public health guidelines (Model 1); and at least once weekly exercise (Model 2). Model 1 trajectories were guideline-adherent exercisers (17.9% of the sample), never guideline exercisers (27.5%), guideline drop-outs (15.2%) and towards guideline (39.4%); Model 2 trajectories were weekly exercise (69.5% of the sample), decreasing (17.4%), increasing (4.8%), and infrequent (8.3%). For both models, at age 15, trajectory membership was predicted by gender, self-efficacy, time spent participating in sport, time spent watching TV, parental socioeconomic status, and academic literacy. At age 25, people in the guideline-adherent exerciser trajectory (model 1) reported better general health relative to other trajectories, Those in the weekly exerciser trajectory (model 2) had better general health and reduced rates of psychological distress, were happier with life and were more optimistic for the future relative to participants in less than weekly trajectory groups. Exercise-promoting interventions for Young People should specifically address the needs of females, people with low self-efficacy, reluctant exercisers, higher academic achievers, and those experiencing socioeconomic disadvantage.

Decreasing Sedentary Time during Lessons Reduces Obesity in Primary School Children: The Active Movement Study

INTRODUCTION

School-based exercise interventions targeted at reducing obesity are often successful in the short term, but they are resource-heavy and do not always lead to long-lasting behaviour changes. This study investigated the effect of reducing sedentary time, rather than increasing exercise, on physical activity (PA) behaviours and obesity in primary school children.

METHODS

Thirty UK state primary schools participated in this cluster-controlled intervention study (IDACI score = 0.15 ± 0.07, free school meals = 26 ± 9%). Twenty-six intervention and 4 control schools (intervention = 3,529, control = 308 children) completed the Physical Activity Questionnaire for Children (PAQ-C) in terms 1 and 3. Three intervention and 3 control schools (intervention = 219, control = 152 children) also measured waist-to-height ratio (WTHR). The Active Movement Intervention is a school-based programme which integrates non-sedentary behaviours such as standing and walking in the classroom. Data were analysed via ANCOVAs and multiple linear regressions.

RESULTS

WTHR was reduced by 8% in the intervention group only (F(2, 285) = 11.387, p < 0.001), and sport participation increased by 10% in the intervention group only (F(1, 232) = 6.982, p = 0.008). Other PAQ-C measures increased significantly in the intervention group, but there was no group*time interaction. Changes in PAQ-C did not predict reductions in WTHR. Instead, the amount of change in WTHR was predicted by intervention group and by baseline WTHR of the pupil, where children with higher baseline WTHR showed greater reductions (F(2, 365) = 77.21, p < 0.001, R2 = 0.30). Socio-economic status (SES), age, or gender did not mediate any of the changes in the PAQ-C or WTHR.

CONCLUSION

Reducing sedentary behaviours during school time can be an effective obesity reduction strategy for primary school children who are overweight. The lack of demographic effects suggests that this method can be effective regardless of the school's SES, pupil age, or gender.

A life course perspective on determinants of discontinuance of active participation in sports activities

Physical inactivity remains a global public health challenge today. Determining why people stop regularly participating in sports is significant to develop targeted intervention strategies for sports promotion and healthy living. As sports participation is dynamic throughout life, a life-course perspective is needed to provide a more comprehensive understanding. This study adopts a life-course perspective to explore the determinants of the change from active participation in sports to becoming inactive. Based on online retrospective survey data collected in the Netherlands, a two-level binary logistic regression model is estimated to capture the effects of socio-demographics, sports motivations, life transitions, and neighborhood characteristics on sports dropout over the lifespan. Results show that dropout from sports is age-specific, and that people are less likely to discontinue sports participation when they have health and weight loss goals. Life transitions have different effects. The cessation of living with physically active people appears to be the most important event to make people stop sporting, followed by having a baby, and then owning the first car. Compared with education-related events, work-related events are more likely to cause people to stop sporting. Moreover, the probability of sports discontinuance may increase when residents feel unsafe doing physical activities in their neighborhoods or when the neighborhood has sufficient greenspace for walking. The findings have implications for supporting sports participants to continue exercising by addressing the barriers.

Effects of a proprioceptive focal stimulation (Equistasi®) on reducing the biomechanical risk factors associated with ACL injury in female footballers

Introduction

Football presents a high rate of lower limb injuries and high incidence of Anterior Cruciate Ligament (ACL) rupture, especially in women. Due to this there is the need to optimize current prevention programs. This study aims to verify the possibility to reduce the biomechanical risk factors associated with ACL injury, through the application of proprioceptive stimulation by means of the Equistasi® device.

Methods

Ten elite female footballers were enrolled and received the device for 4 weeks (5 days/week, 1h/day). Athletes were assessed directly on-field at four time points: T0 and T1 (evaluation without and with the device), T2 (after 2 weeks), T4 (after 4 weeks) while performing two different tasks: Romberg Test, and four sidestep cutting maneuvers bilaterally. Seven video cameras synchronized with a plantar pressure system were used, thirty double colored tapes were applied on anatomical landmarks, and three dimensional coordinates reconstructed. Vertical ground reaction forces and center of pressure data were extracted from the plantar pressure insoles. Hip, knee, and ankle flexion-extension angles and moments were computed as well as abd-adduction joint torques. From the Romberg Test both center of pressure descriptive variables and frequency analysis parameters were extracted. Each variable was compared among the different time frames, T1, T2 and T4, through Friedman Test for non-parametric repeated measures (p<0.05); Wilcoxon Signed Rank Test was used for comparing variables between T0 and T1 (p<0.05) and across the different time frames as follows: T1-T2, T2-T4 and T1-T4.

Results

Statistically significant differences in both posturographic and biomechanical variables between the assessment at T0 and T1 were detected. Reduced hip and knee abduction torques were revealed in association with reduced both ground reaction forces and ankle dorsiflexion torque from T1 up to T4.

Discussion

The proprioceptive stimuli showed to have the potential to improve cutting biomechanics mainly with respect to the ligament and quadriceps dominance theories. Results of the present study, even if preliminary and on a small sample size, could be considered promising towards the inclusion of proprioceptive training in injury prevention programs.

Physical activity among adolescent-parent dyads: 2017-2019 Korea National Health and Nutrition Examination Surveys of Korean adolescents and that of their parents

This study investigated physical activity (PA) levels among adolescents and their parents in South Korea. Repeated cross-sectional data from 2017-2019 Korea National Health and Nutrition Examination Survey (KNHANES) were used. The KNHANES uses a complex, multi-stage probability sample design. Data included 875 Korean adolescents aged 12 to 18years and their parents. Adolescents were asked how many days during the week they were physically active for at least 60 minutes. Compliance was defined as 4+ days per week. Logistic regressions were used and odds ratios and 95% confidence intervals were provided. The adherence to PA compliance and guideline among adolescents (≥60 min/d for at least 4 d/week) and their parents (≥600MET/min per week) were 11.54% and 23.09%, respectively. Parents who adhered to the PA guideline were more likely to have a child who also adhere to the PA than the parents who did not adhere to the PA guideline (OR=2.48, 95% CI=1.39-4.49). Only mothers (OR=1.31, 95% CI=0.65-2.57) and fathers (OR=1.37, 95% CI=0.74-2.55) were not significant in association to their adolescents' PA when complying with the PA guidelines, respectively. Parental PA appears to be important for PA among adolescents. Therefore, strategies to promote PA among adolescents should target families in South Korea.

Sport4Me: A people focused approach to engaging Australians in sport

The traditional model of community club-based sport is fine for those, particularly children and youth, who enjoy the competitive focus and have the skills and commitment to play. But societal preferences during leisure time have changed dramatically over recent decades. However, sport organisations have made limited progress in response to these changes in providing ways in which children and youth can participate outside the traditional competitive structures and environments. In this paper the context of community club-based structures is reviewed leading into an assessment of the associated impact of these structures on sport participation. Children and youth's current motivations to play sport including what makes sport fun to play, are considered. It is then demonstrated that the associations between motivations to play sport and the factors that contribute to fun and enjoyment, are often misaligned for many individuals, with a primary focus on competition-based structures to deliver community club sport. In the final part of the paper a model for community sport organisations where people are put first is proposed - Sport4Me. Sport4Me is about flexible, inclusive, equitable sporting opportunities that focus on friends, fun, physical literacy and play. The model would complement the traditional competitive club-based model and afford participants more choice whilst fostering an environment that promotes lifelong involvement in sport. This model will require structural and cultural changes to the sporting environment and include coaching practices. Sport4Me is an evidence-based model, but it is not radical in its conceptualisation but rather, builds on previously proposed approaches, considers the needs and wants of potential sport participants and widens the scope of sport delivery.

Prevalence and sociodemographic correlates of physical activity and sitting time among South American adolescents: a harmonized analysis of nationally representative cross-sectional surveys

Background

To identify the prevalence and sociodemographic correlates of different domains of physical activity (PA) and higher sitting time among South American adolescents.

Methods

Data from national surveys of 11 South American countries were analyzed, and comprised information on 166,901 adolescents. PA (≥ 60 min/day of moderate-vigorous PA), physical education classes (PEC) (≥ 3 classes/wk), active commuting to school (≥ 1 d/wk), and higher sitting time (≥ 3 h/d) were self-reported. Sociodemographic correlates, such as gender, age, and food security status were explored using a random effect meta-analysis for logistic parameters.

Results

Recommended PA ranged between 7.5% (Brazil) and 19.0% (Suriname). Peru (2.2%) and Guyana (43.1%) presented the lowest prevalence of PEC and active commuting to school, respectively. Higher sitting time was less prevalent in Bolivia (24.6%) and more prevalent in Argentina (55.6%). Compared to girls, boys were more prone to reach recommendations for PA [OR = 1.94(1.65;2.28)]; to reach ≥ 3 PEC [OR = 1.17(1.04;1.33)] and to be active in commuting to school [(OR = 1.14(1.06;1.23)], but less prone to higher sitting time [OR = 0.89(0.82;0.96)]. Older adolescents had less odds of reach PA guidelines [OR = 0.86(0.77; 0.97)] and accumulated higher sitting time [OR = 1.27(1.14;1.41)]. Adolescents with food insecurity reported more PEC [OR = 1.12(1.04;1.21)] and active commuting to school [OR = 1.12(1.02;1.22)] but had less higher sitting time than their food security pairs [OR = 0.89(0.81;0.98)].

Conclusions

Few adolescents reach the PA recommendation. Actions aiming the promotion of PA and the reduction of sitting time must consider girls and older adolescents as target groups, as well as the specifics of each country.

Barriers to high school and university students' physical activity: A systematic review

Physical inactivity commonly occurs throughout one's life, particularly during adolescence and young adulthood. Multiple factors can negatively influence participation in physical activity, but there has been no review examining the barriers to physical activity among high school and university students. Therefore, the aim of this systematic review was to summarize evidence of barriers to the practice of physical activity among high school and university students. The literature search was conducted without time limits using five databases, including CINAHL, Cochrane Library, Embase, PubMed, and Scopus. In total, 59 studies (37 with high school students [n = 22,908] and 22 with university students [n = 15,411]) were included. The main barriers identified in high school and university students were lack of time, lack of motivation, and lack of accessible places. These findings may be useful in designing and implementing evidence-informed interventions and programs for physical activity promotion in students.

Physical activity and sedentary behaviour of female adolescents in Indonesia: A multi-method study on duration, pattern and context

Background/Objective

Exploring comprehensive information on the duration, pattern and context of physical activity and sedentary behaviour is important to develop effective policies and interventions. Especially in lower- and middle-income countries, our understanding of these health-behaviours is limited. Our study aimed to investigate physical activity and sedentary behaviour of female Indonesian adolescents by using a multi-method approach.

Methods

Female adolescents (n = 5; 13–15 years old) from Yogyakarta, Indonesia wore accelerometers and automated wearable cameras for four days, and completed diaries, and interviews between February and March 2020.

Results

Participants’ activity, especially on non-school days, was dominated by light-intensity physical activity. Four of the 5 participants did not meet the physical activity guidelines. Participants spent a great proportion of time on screen-based sedentary behaviour (school days: 83.2% of wear time; non-school days: 75.7% of wear time). During school days, most physical activity and sedentary behaviour was done at school. Screen time was mainly done on the school day evenings and weekend mornings. Participants mostly used smartphones in the bedroom and living room in a solitary environment. Interviews suggest that the high amount of screen time seemed to be influenced by a lack of awareness of current guidelines, the feeling of urgency to check information, and the lack of parental supervision. Non-screen-based sedentary behaviour comprised just over 10% of total camera images.

Conclusion

The use of a multi-method approach facilitated a rich understanding of the duration, patterns, and contexts of physical activity and sedentary behaviour in participants. Future studies might consider using similar methods in a larger sample.

Examining if changes in gender-specific and co-ed intramural programs affect youth physical activity over time: a natural experiment evaluation using school- and student-level data from the COMPASS study

BACKGROUND

Despite the benefits of physical activity (PA), the majority of Canadian youth are falling short of the recommended 60 min of moderate-to-vigorous physical activity (MVPA) per day. School-based physical activity programs such as intramurals, are important opportunities for youth to be physically active. There is limited evidence available on the impact of gender-specific (e.g., female-only, male-only) and co-ed intramurals on youth PA over time, however, evidence suggests female-only intramurals may be important for female MVPA. This research aims to capitalize on a natural experiment to generate practice-based evidence on the impact of changes in gender-specific and co-ed intramurals on youth MVPA over time.

METHODS

This study used linked longitudinal school- and student-level data from Ontario secondary schools in year 5 (Y5:2016-2017), year 6 (Y6: 2017-2018) and year 7 (Y7: 2018-2019) of the COMPASS study. Data on intramurals from 55 schools were used to determine the changes to gender-specific and co-ed intramurals that occurred from Y5 to Y6. Baseline demographic characteristics were measured and data on PA and sport participation were collected in Y5, Y6 and Y7 on a sample of 4417 students. Hierarchical linear mixed regression models were used to estimate how changes in gender-specific and co-ed intramurals were associated with youth MVPA over time.

RESULTS

Participation in intramural, varsity and community sport were all positively and significantly associated with youth MVPA. Changes in gender-specific and co-ed intramurals were not significantly associated with youth MVPA in Y6 or Y7. However, the positive association between maintaining the addition of gender-specific intramurals on female MVPA in Y7 was on par with the significance level of α = 0.05, suggesting that adding gender-specific intramurals may be important for female MVPA.

CONCLUSIONS

Adding gender-specific and co-ed intramurals may not be sufficient strategies to increase PA among youth. Further research should explore the effect of gender-specific intramurals on youth PA, as this study may have been underpowered at the school-level. Gender-specific intramurals may promote a supportive PA environment that promotes MVPA, especially among females. These intramurals may be an important component of more comprehensive strategies to increase youth MVPA.

Disparities and Inequities in Youth Sports

ABSTRACT

Participation in youth sports can have a positive, lasting impact on a child's general health and physical well-being. Unfortunately, some youth populations are unable to participate and/or reap the benefits of sports because of existing inequities. Youth from lower socioeconomic status and ethnic minority children have been found to participate in sports less. These disparities are unfortunately pervasive and likely the result of multiple barriers, including financial and time constraints, limited resources and the inability to access facilities both in and out of school, and lack of familial support. There also exist inequities with regard to sports injury management, including knowledge, access to athletic trainers, and care. This article provides a review of the numerous disparities and inequities in youth sports. Compiling and understanding these data may help develop a framework to make youth sports more equitable and beneficial for all.

Correlations between Physical Activity Participation and the Environment in Children and Adolescents: A Systematic Review and Meta-Analysis Using Ecological Frameworks

Physical activity (PA) and sports are efficient ways to promote the young generation’s physical and mental health and development. This study expected to demonstrate the complexity of correlates associated with children’s and adolescents’ non-organized PA participation. Following the Preferred Reporting Items for Systematic Review and Meta-analysis Protocols (PRISMA), a systematic review and meta-analysis were applied. Seven electronic databases were systematically searched to identify eligible articles based on a series of inclusion and exclusion criteria. The internal validity of the systematic reviews thus identified was evaluated using a validated quality instrument. Calculations were produced in SPSS 27.0 and Comprehensive Meta-Analysis 3.3. Thirty-nine eligible studies (N = 324,953) with moderate to high quality were included. No potential publication bias was detected using statistical analyses. The meta-analysis revealed that the overall ecological factors correlated positively with children and adolescents’ PA; the meta-analytic average of the correlations was (′r = 0.32, p < 0.001). Results from subgroup analysis indicated that theory-based influence factors achieved moderate effect with boys (′r = 0.37, p < 0.001) and girls (′r = 0.32, p < 0.001) in PA participation. Interestingly, higher correlations were found between ecological factors and twins’ PA participation (′r = 0.61, p = 0.001). Further, individual (′r = 0.32, p < 0.001), macro-, and chronosystems factors (′r = 0.50, p < 0.001) appeared slightly more influential than microsystems factors (′r = 0.28, p < 0.001) on children and adolescents’ PA participation. Although findings from the included studies covered were to some extent heterogeneous, it is possible to identify consistent correlates of PA in children and adolescents. The results supported that PA is a complex and multi-dimensional behavior, which is determined by numerous biological, psychological, sociocultural, and environmental factors. Future studies that focus on the integration effect of macrosystem and chronosystem environmental factors, and apply longitudinal designs and objective measurements are encouraged to further unfold the complexity of the ecological system and its implications in promoting children and adolescents’ PA participation.

Scaling junior sport competition: A body-scaling approach?

The design of the junior sport competition environment plays a critical role in attracting and retaining children as life-long participants. Critically, however, the guidelines governing the design of junior sport are rarely scrutinized. With this in mind, our aim is to offer sports authorities a method to systematically assess the suitability of guidelines. The most popular junior ball sport competitions in Australia were assessed in relation to the scaling of task constraints and compared to children's corresponding physical maturation and/or performance measures. This assessment enabled the calculation of pi ratios, which were then used to categorise constraints as either (1) undersized, (2) appropriately sized or (3) oversized. Results revealed that most sports' ask children to play in oversized conditions, particularly in the under 9 to under 12 age groups and in boys' competitions. The task constraints that had the highest percentage of pi ratios appropriately sized were match duration and goal size. Comparatively, ball size and field length had the highest percentage of pi ratios classified as oversized. We contend that the systematic approach applied in this article should be used by sports authorities to understand the extent of scaling constraints in junior sport.

The Interplay of Socioecological Determinants of Work-Life Balance, Subjective Wellbeing and Employee Wellbeing

Today’s workers are struggling to achieve a balance between their work and personal life roles because of both specific needs and limited resources. This study explored the socioecological factors that influence work–life balance (WLB) and how they operate. The relationships between WLB, subjective wellbeing, employee wellbeing and quality time allocation were examined. A total of 1063 responses were received, using an online survey. The results show that relational, community and societal factors directly influenced the individual factors and were indirectly associated with perceived WLB. Individual factors (i.e., personal feelings, behaviours and health) were found to be the crucial determinants of an individual’s perceived WLB. It was found that WLB positively correlated with employee wellbeing and quality and quantity of personal life-time. Subjective wellbeing was found to be a significant moderator in the relationship between WLB and its outcomes. This study demonstrated the process of how workers determine their own WLB by applying the socioecological framework for categorising the determinants and suggested new avenues that improve the whole wellbeing of workers and also foster long-term development of organisations.

A quasi-experimental examination of how changes in school-level intramurals are associated with physical activity among a sample of Canadian secondary school students from the COMPASS study

Introduction

Intramurals in schools may encourage physical activity among youth. Schools are continuously making changes to these intramurals, yet it is not well understood how these changes impact youth physical activity. The main objective of this research was to examine if changes in the number of intramurals were associated with youth physical activity over time with a secondary objective to explore the association between sport participation and physical activity among youth over time.

Methods

This study used three years of linked longitudinal school- and student-level data from Ontario schools in year 5 (Y5: 2016–2017), year 6 (Y6: 2017–2018) and year 7 (Y7: 2018–2019) of the COMPASS study. Data on intramurals from 55 schools were collected from the School Programs and Policies questionnaire to determine intramural changes that were made from Y5 to Y6. Using the COMPASS Student Questionnaire, baseline demographics were collected and data on physical activity and sport participation were measured at Y5, Y6 and Y7 on 4417 students. Hierarchical linear mixed regression models were used to estimate how changes in intramurals were associated with youth physical activity over time.

Results

Changes in school-specific intramurals were not significantly associated with physical activity over time. Intramural, varsity and community sport participation were all positively and significantly associated with youth physical activity among female and males.

Conclusions

Intramural, varsity and community sport participation are important opportunities for youth physical activity. Schools should offer a variety of intramural and varsity sports to encourage physical activity. Although adding intramurals may not be effective at increasing youth physical activity, they may be effective when used in combination with other strategies to increase physical activity.

•

The use of an indicator variable in multi-level modeling is a novel method to evaluate a natural experiment.

•

Intramural, varsity and community sport participation were positively associated with youth physical activity.

•

Intramural changes were not associated with youth physical activity over time.

•

Intramurals may be a useful part of a more comprehensive approach to increasing youth physical activity.

A School-Level Examination of the Association between Programs and Policies and Physical Activity Outcomes among Females from the COMPASS Study

(1) The majority of Canadian youth are not meeting physical activity guidelines, and more female than male youth are falling short of these recommendations. School programs and policies are a viable strategy to improve youth physical activity. However, they may differentially affect female and male activity. This study aimed to examine school-level differences in physical activity outcomes among male and female students and to explore how school programs and policies associate with school-level physical activity outcomes among females. (2) This study used data from 136 schools participating in year 7 (Y7 2018–2019) of the COMPASS study. Data on school programs and policies and on student physical activity were collected. School-level means and percentages for outcomes were calculated and compared between males and females and the impact of physical activity programs and policies on female physical activity outcomes were examined. (3) More males met the guidelines, achieved more strength training days and physical activity minutes compared to females. The number of female varsity sports, community partnerships and fitness ambassadors were all positively and significantly associated with female physical activity. (4) Supportive physical activity environments fostered by offering varsity sports, establishing community partnerships and positive role models may promote physical activity among female youth.

Examining If Changes in the Type of School-Based Intramural Programs Affect Youth Physical Activity over Time: A Natural Experiment Evaluation

(1) School-based physical activity programs such as intramurals provide youth with inclusive opportunities to be physically active, yet we know little about how types of intramurals (e.g., team and individual sports) may contribute to youth MVPA. This research aims to evaluate how real-world changes in types of intramurals available in schools impact youth physical activity over time. (2) This study used three years of longitudinal school- and student-level data from Ontario schools participating in year 5 (2016–2017), year 6 (2017–2018) and year 7 (2018–2019) of the COMPASS study. Data on types of intramural programs from 55 schools were obtained, baseline demographic characteristics were measured and data on physical activity and sport participation were collected on a sample of 4417 students. Hierarchical linear mixed regression models were used to estimate how changes in the type of intramurals associate with youth MVPA over time. (3) Regardless of participation, adding individual and team intramurals was significantly and positively associated with female MVPA in Y6. (4) The indirect, but positive relationship between adding individual and team intramurals and female MVPA may be explained by other characteristics of the school environment that are conducive to female MVPA.

Analysis of the Relationship between Tobacco Smoking and Physical Activity in Adolescence: A Gender Specific Study

Background and Objective: Although smoking and the physical activity level (PAL) are important determinants of health status in adolescence, there is a lack of information on the relationship between smoking and PAL in early adolescence. The objective of this study was to evaluate the gender-specific relationship between smoking and PAL in 14-to-16-year-old adolescents. Materials and Methods: The sample included 650 adolescents (337 girls, 14.7 ± 0.5 years at first testing wave) from Bosnia and Herzegovina. During the first testing wave, participants were tested using structured questionnaires. Second testing was commenced after approximately 20 months (16.4 ± 0.6 years). The variables were age, gender, socioeconomic status, living environment, cigarette smoking (predictors), and PAL (criterion). Predictors were measured at the first wave, and criterion at the first-wave and second-wave. Results: For girls, smoking was negatively correlated to PAL at the first-wave (OR: 0.75, 95% CI: 0.55-0.95) and at the second-wave (OR: 0.73, 95% CI: 0.71-0.96). No significant association between smoking and PAL was found for boys. Results suggest that adolescent boys and girls do not follow the equal trajectories when it comes to relationships between smoking and PAL. Conclusions: In developing promotional public health actions related to a decrease of smoking and increase of PAL, a gender-specific approach is highly recommended. Further studies analyzing the cause-effect relationship between consumption of other types of psychoactive substances and PAL in this age group are warranted.

'One hundred dollars is a big help, but to continue, it's a challenge': A qualitative study exploring correlates and barriers to Active Kids voucher uptake in western Sydney

INTRODUCTION

The Active Kids voucher is a universal, state-wide voucher program, provided by the New South Wales (NSW) Government, Office of Sport. All school-aged children in NSW are eligible to receive a voucher to reduce registration costs of structured physical activity programs. This study explores reasons behind lower uptake among children who are overweight or obese, from cultural and linguistically diverse families and those living in low socio-economic areas.

METHODS

Participants were recruited through a convenience sample of parent/carers who participated in the NSW Health Go4Fun program. Qualitative data were collected using focus groups. The Framework method was adapted for the analysis, taking an interpretive phenomenological approach.

RESULTS

Study participants (n = 54) were all parents of children who were overweight or obese from both low and high socio-economic status (SES). Most reported speaking a primary language other than English at home (65%). Parents were mostly aware of the Active Kids program (91%) and reported that the voucher had a positive impact on their children's participation in structured physical activity. A range of socio-ecological factors, in addition to activity cost, influenced whether parents were able to use an Active Kids voucher and participate in structured physical activity.

CONCLUSIONS

The Active Kids voucher does not alleviate all barriers, particularly for families living in low socio-economic areas. Engagement of this population in structured physical activities using the Active Kids vouchers could be strengthened through the implementation of effective interventions which comprehensively address the remaining barriers, such as access and flexibility of programs with local stakeholders and activity providers.

Familial and Parental Predictors of Physical Activity in Late Adolescence: Prospective Analysis over a Two-Year Period

Children’s health behaviors are highly influenced by their parents and family. This study aimed to prospectively evaluate the parental/familial factors associated with physical activity levels (PALs) among older adolescents. The participants were 766 adolescents, who were prospectively observed at baseline (when they were 16 years of age), at first follow-up measurement (FU1; 17 years of age), and second follow-up measurement (FU2; 18 years of age). Sociodemographic factors (age, gender, socioeconomic status, and sport participation) and parental/familial variables were evaluated at baseline. PALs (evidenced by the Physical-Activity Questionnaire-for-Adolescents) were prospectively evidenced at baseline, FU1, and FU2. Factorial analysis of variance for repeated measurements showed a significant decrease in PALs during the study course (F = 83.05, p < 0.001). Sport participation and male gender were significant predictors of PALs at baseline, FU1, and FU2. Logistic regression, controlled for sport participation and male gender, evidenced paternal education as a significant predictor of baseline PALs. Parental conflict was a significant predictor of PALs in all three testing waves. The significant influence of paternal education on the children’s PALs existed from younger adolescence until the age of 17 years. The association between parental conflict and PALs developed in older adolescence. These results should be used in the development of specific and targeted interventions aimed at the improvement of PALs and a reduction of sedentarism in youth.

A Case of Leveraging a Mega-Sport Event for a Sport Participation and Sport Tourism Legacy: A Prospective Longitudinal Case Study of Whistler Adaptive Sports

Sport participation legacies are often offered as reasons to host mega-sport events, yet there is little evidence to demonstrate the claim’s legitimacy, thus we examine “What did Whistler Sports do to leverage the Vancouver 2010 Olympic and Paralympic Winter Games to facilitate a sport tourism legacy?”. Through a prospective longitudinal case study of WAS and application of the temporal extension of the socioecological framework, multiple data sources were analyzed from over a decade beginning before the event until 2019. The findings reveal the situated and embedded nature of mega-sport event legacies i.e., context. These depend upon a network of facilitators such as local, provincial, and federal policies; pre-event and post-event vision and strategies from local communities and sport organizations; the development of a pool of willing and flexible volunteers. Together these were strategically leveraged to overcome sport participation and sport tourism barriers for people with disabilities. The sport, tourism, and sport tourism experience reflected Whistler’s natural and infrastructure advantage and the needs and desires of locals and visitors with access needs that could not have occurred without the capital injection of the Vancouver 2010 Olympic and Paralympic Games. Leveraging the mega-sport event opportunities required leadership and a strategic vision for repositioning to a year-round program. This strategic change also opened new sport and sport tourism opportunities for current participants but importantly brought new participants and their friendship groups to Whistler over the post-event decade for year-round sustainable adaptive sport opportunities.

Association between health insurance status and malignant glioma

Background

Prior studies have suggested an association between patient socioeconomic status and brain tumors. In the present study we attempt to indirectly validate the findings, using health insurance status as a proxy for socioeconomic status.

Methods

There are 2 types of health insurance in Germany: statutory and private. Owing to regulations, low- and middle-income residents are typically statutory insured, whereas high-income residents have the option of choosing a private insurance. We compared the frequencies of privately insured patients suffering from malignant neoplasms of the brain with the corresponding frequencies among other neurosurgical patients at our hospital and among the German population. To correct for age, sex, and distance from the hospital, we included these variables as predictors in logistic and binomial regression.

Results

A significant association (odds ratio [OR] = 1.59, CI = 1.45-1.74, P < .001) between health insurance status and brain tumors was found. The association is independent of patients' sex or age. Whereas privately insured patients generally tend to come from farther away, such a relationship was not observed for patients suffering from brain tumors. Comparing the out of house and in-house brain tumor patients showed no selection bias on our side.

Conclusion

Previous studies have found that people with a higher income, level of education, or socioeconomic status are more likely to suffer from malignant brain tumors. Our findings are in line with these studies. Although the reason behind the association remains unclear, the probability that our results are due to some random effect in the data is extremely low.

Gender Differences in the Level of Achievement of Gymnastic and Acrobatic Skills

Physical education should provide the opportunities to progressively integrate motor tasks with different levels of complexity from early ages to adolescence. The objective of this research was to analyze gender differences in the level of achievement of basic acrobatic skills of students of physical activity sciences in their non-university stages. This cross-sectional study with descriptive design was carried out with a total of 675 first-year Spanish university students distributed over eight academic years. An initial test of two acrobatic skills was performed. The instruments used for data collection were a video camera and observation templates. The SPSS 26.0 computer program was used for data analysis. The main results show a poor and insufficient level of technical achievement by both genders, but more pronounced for men. The most deficient phases were those related to extension movements of different segments of the body and movements that require coordination and stability in the descent phases of acrobatics, and men were less flexible in both phases. Non-university training of the content associated with basic gymnastic and acrobatic skills is being deficient within the subject of physical education with a downward trend of not only the development of sports skills but also of physical abilities such as flexibility and strength.

Exploring the relationship between adolescent biological maturation, physical activity, and sedentary behaviour: a systematic review and narrative synthesis

CONTEXT

Across adolescence, there is a notable decline in physical activity in boys and girls. Maturational timing may be a risk factor for disengagement from physical activity and increased sedentary behaviours during adolescence.

OBJECTIVE

This systematic review aimed to summarise literature that examined the relationship between maturational timing, physical activity and sedentary behaviour in adolescents.

METHODS

Six electronic databases were searched for articles that assessed biological maturation and physical activity (including sports participation and active transportation) or sedentary behaviours in adolescents. Two reviewers conducted title, abstract, and full-text screening, reference and forward citation searches. Included articles were evaluated for quality using a standardised tool. A narrative synthesis was used to analyse the findings due to the heterogeneity of the studies.

RESULTS

Searches yielded 78 articles (64 unique studies) that met the inclusion criteria, representing 242,316 participants (153,179 unique). Studies ranged from 30.0% (low) to 91.7% (high) in quality. An inverse relationship between maturational timing and physical activity (in 50 and 60% of studies in boys and girls, respectively) and a positive relationship between maturational timing and sedentary behaviour (in 100% and 53% of studies in boys and girls, respectively) was most commonly reported. Evidence supporting an association between maturational timing, sports participation, and active transportation was inconsistent.

CONCLUSIONS

While this review demonstrates some evidence for early maturational timing as a risk factor for disengagement from physical activity and increase in sedentary behaviours, the reviewed literature also demonstrates that this relationship is complex. Future research that tracks maturity-related variations in physical activity and sedentary behaviours over adolescence is warranted.

Physical activity and sport participation characteristics of Indigenous children registered in the Active Kids voucher program in New South Wales

OBJECTIVES

Investigate sociodemographic factors associated with physical activity and sport participation among Indigenous children registered in the New South Wales (NSW) government-funded Active Kids voucher program in 2018, including comparison with non-Indigenous children.

DESIGN

Cross-sectional study.

METHODS

The Active Kids voucher program aims to support the cost of children's sport and physical activities. All children aged 5-18 years in NSW are eligible for a voucher. To register, parent/carers report child sociodemographic characteristics, physical activity, sport participation and optional height and weight. Regression models were used to determine which sociodemographic characteristics were associated with meeting physical activity guidelines and sport participation for Indigenous and non-Indigenous children.

RESULTS

Of the 671,375 children aged 5-18 years, 36,129 (5.4%) were Indigenous. More Indigenous children than non-Indigenous children met the physical activity guidelines before registering in the Active Kids program. Indigenous children had greater odds of meeting physical activity guidelines across all socio-economic quartiles. Among non-Indigenous children, odds reduced with social disadvantage. Indigenous children (38%) were less likely to participate in organised physical activity and sport sessions at least twice a week compared to non-Indigenous children (43%). Indigenous children living in major cities had higher sport participation levels compared with those living in outer regional and remote areas.

CONCLUSIONS

The Active Kids voucher program achieved population representative reach among Indigenous children, whose physical activity levels were higher than non-Indigenous children across all socioeconomic quartiles. The program has potential to supplement Indigenous children's physical activity levels using organised sessions and reduce sport drop-out among older children.

Making football safer for women: a systematic review and meta-analysis of injury prevention programmes in 11 773 female football (soccer) players

Objective

To evaluate the effects of injury prevention programmes on injury incidence in any women’s football code; explore relationships between training components and injury risk; and report injury incidence for women’s football.

Design

Systematic review and meta-analysis.

Data sources

Nine databases searched in August 2019.

Eligibility criteria

Randomised controlled trials evaluating any injury prevention programme (eg, exercise, education, braces) were included. Study inclusion criteria were: ≥20 female football players in each study arm (any age, football code or participation level) and injury incidence reporting.

Results

Twelve studies, all in soccer, met inclusion criteria, with nine involving adolescent teams (aged <18 years). All studies (except one) had a high risk of bias. Eleven studies examined exercise-based programmes, with most (9/11) including multiple (≥2) training components (eg, strength, plyometric, balance exercises). Multicomponent exercise programmes reduced overall (any reported) injuries (incidence rate ratio (IRR) 0.73, 95% CI 0.59 to 0.91) and ACL injuries (IRR 0.55, 95% CI 0.32 to 0.92). For exercise-based strategies (single-component and multicomponent), hamstring injuries were also reduced (IRR 0.40, 95% CI 0.17 to 0.95). While exercise-based strategies resulted in less knee, ankle and hip/groin injuries, and the use of multiple training components was associated with greater reductions in overall and knee injuries, further studies would be required to increase the precision of these results. The incidence of overall injuries in women’s football was 3.4 per 1000 exposure hours; with ankle injuries most common.

Conclusion

In women’s football, there is low-level evidence that multicomponent, exercise-based programmes reduce overall and ACL injuries by 27% and 45%, respectively.

Investigating Adolescent Girls' Perceptions and Experiences of School-Based Physical Activity to Inform the Girls' Peer Activity Intervention Study

BACKGROUND

Adolescent girls are likely to be less active than adolescent boys. A range of factors including multiple psychosocial aspects are thought to influence their engagement in physical activity (PA). This study aimed to explore adolescent girls' perceptions and experiences of school-based PA to inform a subsequent intervention, the Girls Peer Activity (G-PACT) project.

METHODS

The Youth Activity Profile was used to assess adolescent girls' current PA levels. Open-ended questions were used to investigate girls' perceptions and experiences of school-based PA. Focus groups stratified by PA level were then conducted to explore their perceptions and experiences in depth. The focus group data were analyzed using inductive thematic analysis.

RESULTS

The master themes emanating from the focus groups were noncompetitive activities and after-school sport culture for lower active girls. Higher active girls' master themes were PA perceptions and physical education. Regardless of activity level, participants reported greater enjoyment from PA when participating with friends and having choice over activities provided within the school setting.

CONCLUSIONS

The findings highlight the importance of choice, peer groupings, noncompetitive opportunities, and PA competence to adolescent girls' school-based PA behaviors. The school environment can support and restrict girls' engagement in PA. The findings will be applied to the design, content, and implementation of the G-PACT project.

Lights out, let's dance! An investigation into participation in No Lights, No Lycra and its association with health and wellbeing

BACKGROUND

Organized, leisure time physical activities are an important part of a population approach to increase total physical activity participation. Dancing is a type of organized leisure time activity which may be utilized to enhance public health. Individuals commonly participate in dance during childhood however few maintain participation into adulthood, dropping out of the activity while young. This study aimed to investigate who participates in an emerging dance activity, "No Lights, No Lycra", which encourages people to participate in free-form dancing in the dark for 60 min designed as an inclusive, nonjudgmental, drug and alcohol-free community setting. This version of dance provides a modified opportunity for organized leisure time physical activity. No Lights, No Lycra has recorded increases in attendance at their events over the past decade. This popularity warrants an investigation into participant's demographic characteristics, their total physical activity, as well as their motivations for dancing in the dark and any impacts on health and wellbeing.

METHODS

This study invited No Lights, No Lycra participants from across Australia to complete a cross-sectional, self-report online survey. Participants were recruited while attending an organized session or through social media channels. The descriptive data provided through survey responses were analyzed using IBM SPSS Statistics.

RESULTS

Participants (n = 1190, 92% Female) reported their main reason for dancing in the dark was to have fun. Most participants were insufficiently active, with 88% of responders not meeting physical activity guidelines. The No Lights, No Lycra dance sessions contributed 23% of their total annual participation in organized physical activities.

CONCLUSION

No Lights, No Lycra attracts adult women, rather than the typical dance participants - children; These women did not meet physical activity guidelines and typically had low levels of engagement in organized physical activity. Participation in No Lights, No Lycra, shows promise to increase women's physical activity. This study into No Lights, No Lycra demonstrates how dance can be modified to engage a relatively inactive portion of the community. More should be done to understand how modifications to organized sport and physical activities can motivate and maintain engagement of typically inactive people.

Factors influencing women in physical activity programs in Malaysia

The majority of research on factors associated with women participation in physical activity (PA) has been in developed countries with limited research in developing countries. Few women in Malaysia are active at the recommended levels for health, and activity rates are less than developed countries. Little research has focused specially on physically active Malaysian women and the factors that contribute to them becoming and staying active in PA programs. This lack of knowledge hinders the tailored development and implementation of PA programs to meet their needs. The aim of this study was to identify the factors of participation in PA programs for Malaysian women. The social-ecological model was used to investigate and theme the factors. Focus group discussion was conducted with participants in six PA programs targeted specifically to women. Thirty-seven women were involved in the focus group discussion, with ages ranging from 19 to 82 years. Inductive and deductive content analysis was conducted from verbatim transcripts using NVivo. Inductive content analysis allowed raw data and second-order themes to emerge. Findings revealed social support structures, tailored programs for women, and location were key contributors that encouraged women to participate in these programs. The similarity in contributors between women in non-western and western countries signifies a prime opportunity for bi-lateral relationships to be formed to enable the enhancement of program development relevant to different ethnicities and cultures within or across countries.

Body mass index and physical fitness among Chinese adolescents from Shandong Province: a cross-sectional study

Background

This study aimed to describe the most recent prevalence estimates of adolescent body mass index (BMI) and physical fitness from thirteen regions in Shandong Province, China and to examine differences by social-economic status (SES).

Methods

The participants were 27,955 adolescents (mean age = 14.4 ± 1.8 years; 13,791 girls) enrolled from 91 public middle and high schools randomly selected from 13 administrative regions in Shandong Province. The Chinese National Student Physical Fitness Standard was employed to assess participants’ fitness once during the school semester. Fitness assessments included BMI, a 50-m sprint run, sit-and-reach, standing-broad jump, sit-ups, pull-ups, and a 1000 m/boy or 800 m/girl distance run. Participants’ fitness performance was categorized as excellent, good, pass, or no pass.

Results

The percent of Chinese adolescents categorized as “no pass” ranged from just 8.9% for BMI to 67.1% for boy pull-ups. The percent of Chinese adolescents categorized as “excellent” ranged from 5.0% for the girl sit-ups to 35.4% for the 50-m sprint run. Approximately 8.4% of the sample was categorized as excellent for BMI. SES significantly predicted both girl and boy continuous distance run scores (p < 0.05). Adolescents in lower SES strata had lower odds of achieving “pass” or better on cardio-respiratory endurance tests, muscular fitness tests, and flexibility tests, but higher odds of achieving “pass” or better on BMI compared to adolescents who were high SES (p < 0.05).

Conclusions

The large sample of the adolescents in Shandong province, on average, had healthy weight status and achieved a high prevalence of “pass” or better on physical fitness tests. Adolescents who were low SES demonstrated poorer cardio-respiratory endurance, muscular fitness, and flexibility test achievement but better BMI achievement compared to high SES adolescents in Shandong Province, China.

The impact of life stresses on physical activity participation during adolescence: A 5-year longitudinal study

Life stresses (LS) could affect levels of physical activity (PA) during adolescence, however research is limited. As different types of PA may have different determinants, the effects of LS on participation in moderate-to-vigorous PA (MVPA) and on organized and unorganized PA (OPA, UPA) were examined in a sample of 937 students (10-11 years-old) followed up over five years. Questionnaires were administered three times per year as part of the Monitoring Activities for Teenagers to Comprehend their Habits (MATCH) study. A total of 16 survey cycles were available for this analysis. At each survey cycle, participants reported exposure to nineteen LS, number of days per week attaining at least 60 min of MVPA, and participation in OPA and in UPA. LS were classified as personal or extrinsic life events, or personal or extrinsic life circumstances. Relationships among the four LS categories and PA outcomes were assessed using gender stratified mixed effects models. Personal circumstances attenuated the increase in MVPA in late childhood, and accentuated the decrease in MVPA in early adolescence (p < 0.001). In contrast, experiencing more extrinsic events attenuated the decrease in the number of reported UPA (p < 0.05). Among girls, experiencing more personal events attenuated the decrease in the number of UPA and OPA by 4.8% and 5.1% respectively. Among boys, experiencing more extrinsic circumstances attenuated the decrease in the number of UPA by 3.4%. The effect of LS on PA differed by gender and by type of PA, highlighting the need for careful tailoring of interventions.

Tracking of Physical Activity, Sport Participation, and Sedentary Behaviors over Four Years of High School

Background: The aim of the present study was to investigate the extent of tracking of physical activity (PA), sports participation (SP), and sedentary behaviors (SB) over four years of high school education among the Croatian Physical Activity in Adolescence Longitudinal Study (CRO-PALS) cohort. Methods: In this investigation, participants were 844 high school students (15.6 years at baseline; 49% girls). The SHAPES questionnaire was used to assess PA, SP, and SB at ages 15, 16, 17, and 18 and tracking was assessed using generalized estimating equations. Results: Tracking coefficients for PA were similar in both sexes, ranged from 0.49 to 0.61, and indicated moderate tracking, while the tracking of SB tended to be somewhat higher over the four years of follow-up (β = 0.60–0.72). Youth that participated in sports at baseline had a 16 to 28 times higher odds of continued participation at follow-up, depending on the type of sport and gender. Finally, both low physical activity and high screen time showed strong tracking in both genders. Conclusion: PA and SB tracked moderately between ages 15 and 18. Moreover, the strong tracking of low PA and high screen time indicates that the detection of these risk factors at the beginning of high school should be advocated.

Time-use and environmental determinants of dropout from organized youth football and tennis

BACKGROUND

Many adolescents drop out of organized sports. Lack of motivation and competing priorities are known as important reasons for dropout. However, time use factors as well as environmental determinants have been largely neglected in the current literature on dropout from youth sports. The aim of this study is to investigate how (changes in) time use and characteristics of the physical environment determine dropout from football and tennis among adolescents.

METHODS

Data on time use and background characteristics were collected through online surveys in 2015 and 2016 among adolescents aged 13-21 (N = 2555), including both the dropped outs and those who still continued membership of their football or tennis clubs. Physical environmental determinants (travel distance to the sports club, and neighbourhood density) were measured objectively. Binary logistic regression analyses were carried out for football and tennis separately to examine the associations between time use (time spent on various activities and changes related to the school and job situation), and environmental factors on the probability of dropping out from sports.

RESULTS

Time spent on sports outside the context of the sports club, and time spent on social or voluntary activities at the sports club was positively associated with continuing being football and tennis members. Tennis players who changed schools or participated in two sports at the same time had a higher probability of dropping out, whereas tennis players who travelled greater distances from home to the tennis club were less likely to drop out.

CONCLUSIONS

Determinants of dropout differed between football and tennis. However, time use variables were important predictors of dropout from football as well as tennis, whereas environmental determinants hardly contributed to the prediction of dropout. To keep youths involved in organized sports, this study recommends that sports professionals should: 1) offer flexibility in training and competition schedules, 2) stimulate participation in social activities and voluntary work at the sports club, 3) pay special attention to their needs and preferences, and 4) encourage possibilities to practice and play sports outside of regular training hours, for instance at the sports club or at playgrounds or parks in the neighbourhood.

Girls' transition from participation in a modified sport program to club sport competition - a study of longitudinal patterns and correlates

BACKGROUND

Participation in sport is very popular for young children. Many children participate in entry-level modified sports programs. These programs are modified to match the developmental capacity of children and are aimed at development of fundamental motor skills and sport-specific skills, rather than competition. There is limited research on the longitudinal tracking of children in these programs and into club-based competition. Research suggests that most children drop-out of the sport and do not transition into club-based competition. Furthermore, more females than males drop-out of sport. The aim of this study is to investigate longitudinally, the patterns and demographic predictors of children's transition from modified sport programs to club sport competition for females.

METHODS

This study analysed sport participation for females in a popular Australian, predominantly female, sport. Players of the modified sports program were followed over 4 years to determine their pattern of transition: transition to junior player status, withdraw from the sport, or continue in the modified program. Pattern of transition was compared across age (4-10), geographical region (metropolitan/non-metropolitan) and socio-economic status (SES). Logistic regression was used to model the effect of the three factors on the likelihood of transition.

RESULTS

A total of 13,760 female children (aged 4-10) participated in the modified sport in the first year. The majority (59%) transitioned from the modified sport program and into club competition. However the rate of transition varied with age, residential location and socio-economic status, and there was an interaction between region and SES, with SES having a significant influence on transition in the metropolitan region. The peak sport entry age with the highest rates of transition was 7-9 years.

CONCLUSIONS

This study demonstrated that whilst the majority of female participants continued participantion and tranisitioned from the modified sport program and into club competition, the strongest correlate of transition was age of entry, with transition rate peaking among those who commenced at age 7-9 years. It is recommended that, in order to maximise continued participation, sport policy and strategic developments should consider the possibility that targeting the very young is not the optimum recruitment strategy for fostering continued sport participation.

Demographic characteristics and type/frequency of physical activity participation in a large sample of 21,603 Australian people

BACKGROUND

Regular physical activity (PA) is imperative for good health and there are many different ways that people can be active. There are a range of health, PA and sport policies aiming to get more people active more often. Much research has been directed towards understanding the determinants of inactivity and PA. However, it is important to understand the differences not only between inactive and active people, but also between activity contexts (for example participation in sport compared to non-sport activities), in order to align policies and strategies to engage market segments who have different participation preferences and accessibility. The aim of this study was to investigate demographic correlates of the propensity to be physically inactive or active within different contexts, and at different levels of frequency of participation.

METHODS

Data from the Australian Exercise, Recreation and Sport Survey was used for this analysis. This included information on the type, frequency and duration of leisure-time PA for Australians aged 15 years and over. Reported PA participation in the two-week period prior to the survey was used to allocate respondents into three categories: no PA, non-sport PA only, and sport. Subsequently, sport participants were further categorised according to frequency of participation. Potential demographic correlates included sex, age, education, employment, marital status, language spoken, having a condition that restricts life, children, and socio-economic status.

RESULTS

The survey included 21,603 people. Bivariate chi-squared analysis showed that there were significant differences between the profiles of leisure-time PA participation across all demographic variables, except the variable languages spoken at home. Ordinal regression analysis showed that the same demographic variables were also correlated with the propensity to engage in more organised and competitive PA contexts, and to participate more frequently.

CONCLUSIONS

People who were female, older, married or had a disability were less likely to participate in sport. Therefore when designing PA opportunities to engage those who are inactive, particularly those that are organised by a club or group, we need to ensure that appropriate strategies are developed, and tailored sport products offered, to ensure greater opportunities for increased diversity of participation in sport.

Physical fitness and anthropometric characteristics among adolescents living in urban or rural areas of Kosovo

Background

High physical fitness levels in childhood and adolescence are associated with positive health-related outcomes later in life. Albeit many researchers investigated rural-urban differences in physical fitness, the outcomes of these studies are inconsistent and data on Kosovo are widely missing. Thus, this study aims to examine anthropometric and physical fitness parameters in 14 to 15 year old Kosovan adolescents living in rural and urban areas.

Methods

Two schools from Pristina (mostly urban population) and two schools in the surrounding villages of the district of Deçan (mostly rural population) were selected. Anthropometric and physical fitness parameters were determined from a total of 354 adolescents (216 urban: 14.5 ± 0.4 years, 138 rural: age 14.5 ± 0.4 years) who volunteered to participate in this cross-sectional study performed in 2013/14.

Results

The prevalence of overweight and obesity was 18.9% in girls and 28.2% in males and excess body fat was detected in 18.2% of the girls and 15.9% of the boys with no differences between rural and urban adolescents. Rural adolescents performed slightly better in relative handgrip strength (+4.7%, p = 0.032) and running speed (10 m: +2.2%, p = 0.012; 20 m: +1.9%, p = 0.035), but no other differences were detected in standing long jump, counter movement jump, cardiorespiratory fitness and sit and reach test. A multinomial logistic regression analysis revealed that being a female was associated with a lower relative risk for overweight (RR = 0.11, 95% CI: 0.03–0.34, p < 0.001) and high body fat content (RR = 0.20, 95% CI: 0.05–0.56, p < 0.001). In addition, higher handgrip strength, longer sprinting time and lower aerobic fitness were associated with a higher relative risk for overweight and excess body fat. In contrast, lower handgrip strength increased the risk for experiencing thinness (RR = 0.92, 95% CI: 0.89–0.96, p < 0.001).

Conclusions

It could be shown that there is a high prevalence of overweight and obesity, especially in 14 to 15 year old boys in Kosovo which does not differ between rural and urban areas. Worse physical performance is associated with a higher risk for overweight and obesity highlighting the importance for interventions in this area and for starting longitudinal observations of a secular trend.

Physical Activity Perceptions in Adolescents: A Qualitative Study Involving Photo Elicitation and Discussion Groups

Adolescence is a key period in life when most of the healthy habits that will affect health during adulthood are established. Numerous interventions based on the acquisition of regular physical activity (PA) in the adolescent population have so far yielded no success, mainly in the long term. Qualitative phenomenological research was used to identify adolescents’ perceived barriers and motivations to regular PA practice, and how they form the concept of PA through thought and action. This study constitutes an explicative design using photo elicitation (PE) and discussion group (DG) techniques to explore different aspects and meanings associated with PA, as well as their perceptions toward PA practice. The study was conducted on adolescents from a randomly selected district in Barcelona (Catalonia), Spain. Through the use of PE, a total of 67 photographs were analyzed. A DG was conducted with a group of 10 teenagers. Input from the DG was examined using interpretative phenomenological analysis. The findings show that social, familial, and environmental factors become motivational elements for the regular practice of PA. The findings observed relevant aspects linked to general barriers and to particular ones associated with young women. This study also considered implications for future interventions.

The influence of a Healthy Welcoming Environment on participation in club sport by adolescent girls: a longitudinal study

Background

This study investigated the perceived influence of a Healthy Welcoming Environment (HWE) on participation in sports clubs among adolescent girls, and how these perceptions changed longitudinally. HWE was defined in terms of a set of health promotion policies advocated by a health promotion foundation as the basis of sport club health promotion practice to promote structural reform in state sporting organisations and their affiliated associations and clubs. These included sports injury prevention, smoke-free, responsible serving of alcohol, sun protection, healthy eating, and welcoming and inclusive environments.

Methods

Year 7 and 11 female students from metropolitan (n = 17) and non-metropolitan secondary schools (n = 14) in Australia were invited to participate in three annual surveys. These surveys collected information about current or past membership of a sports club and the influence of HWEs on their decision to participate (or not) in a sports club.

Results

Year 7 (n = 328; 74.5%) and Year 11 (n = 112; 25.5%) female students completed all three waves (19.6% response rate; 82.7 and 74.0% retention rate). Most agreed that characteristics of HWEs were a positive influence on their participation in sports clubs, except those relating to alcohol and Sunsmart. Welcoming factors had consistent high agreement among respondents. Alcohol and friendliness factors of the club were regarded as being positively influential by higher percentages of non-metropolitan than metropolitan respondents.

Conclusions

Welcoming factors were the most positive influences on decisions to participate in sports clubs. These factors may be important in reducing barriers to sport participation. Strategies supporting the social environment within sports clubs should be prioritised.

Associations between Parental and Friend Social Support and Children's Physical Activity and Time Spent outside Playing

The purpose of this study was to examine the structural validity of a parent and a child questionnaire that assessed parental and friends' influences on children's physical activity and investigate the associations between the derived factors, physical activity, and time spent outside. Children (N = 154, mean age = 11.7) and 144 of their parents completed questionnaires assessing parental and friends' influences on children's physical activity. Children wore a pedometer for six days. Exploratory factor analyses revealed four factors for the parental and five for the child's questionnaire that explained 66.71% and 63.85% of the variance, respectively. Five factors were significantly associated with physical activity and five significantly associated with time spent outside. Higher correlations were revealed between “general friend support,” “friends' activity norms,” and physical activity (r = 0.343 and 0.333 resp., p < 0.001) and between “general friend support” and time spent outside (r = 0.460, p < 0.001). Obtaining information relating to parental and friends' influences on physical activity from both parents and children may provide a more complete picture of influences. Parents and friends seem to influence children's physical activity behavior and time spent outside, but friends' influences may have a stronger impact on children's behaviors.

Determinants of organised sports participation patterns during the transition from childhood to adolescence in Germany: results of a nationwide cohort study

BACKGROUND

Organised sports (OS) participation is an important health behaviour but it seems to decline from childhood to adolescence. The aim of this study was to investigate OS participation patterns from childhood to adolescence and potential determinants for those patterns.

METHODS

Data from the German Health Interview and Examination Survey for Children and Adolescents (KiGGS) cohort study with a 6 year follow-up period were used (KiGGS0: 2003-06, KiGGS1: 2009-12). Participants aged 6-10 years at KiGGS0, who were aged 12-16 at KiGGS1, were included (n = 3790). The outcome variable was 'OS participation' between KiGGS0 and KiGGS1 with the categories 'maintenance' (reference), 'dropout', 'commencement' and 'nonparticipation'. Relative risk ratios (RRRs) were calculated using multinomial logistic regression to identify potential predictors for OS patterns. Socio-demographic, family-related, health-related, behavioural and environmental factors were considered as independent variables.

RESULTS

48.5 % maintained OS, 20.5 % dropped out, 12.3 % commenced OS between KiGGS0 and KiGGS1 and 18.7 % did not participate at both times. The RRRs for dropout rather than maintenance were 0.6 (95 % Cl 0.5-0.7) for boys versus girls, 1.5 (1.3-1.9) for the age group 8-10 versus 6-7 years, 0.7 (0.5-0.9) for high versus intermediate parental education, 1.4 (1.1-1.8) for low versus middle household income, 1.4 (1.0-1.8) for below-average versus average motor fitness. The RRRs for commencement rather than maintenance were 0.6 (0.5-0.8) for boys versus girls, 0.6 (0.5-0.8) for the age group 8-10 versus 6-7 years, 1.5 (1.1-2.1) for low versus intermediate parental education, 1.5 (1.1-2.0) for low versus middle household income, 0.7 (0.5-1.0) for no single-parent versus single parent family, 1.8 (1.3-2.5) for below-average and 0.6 (0.4-0.8) for above-average versus average motor fitness, and 1.4 (1.1-1.9) for high versus middle screen-based media use. The RRRs for abstinence rather than maintenance were 0.6 (0.4-0.7) for boys versus girls, 1.5 (1.1-2.0) for low versus intermediate parental education, 2.2 (1.7-2.8) for low and 0.6 (0.5-0.8) for high versus middle household income, 1.6 (1.2-2.1) for psychopathological problems versus no problems, 1.7 (1.3-2.2) for below-average and 0.4 (0.3-0.6) for above-average versus average motor fitness, and 1.6 (1.0-2.6) for rural versus metropolitan residential area.

CONCLUSIONS

OS participation rates among all children living in Germany need to be improved. More tailored offerings are needed which consider the preferences and interests of adolescents as well as a cooperation between public health actors to reduce barriers to OS.

Population levels of sport participation: implications for sport policy

Background

Participation in sport can contribute to health-enhancing levels of leisure-time physical activity. There are recent reports that participation in sport in Australia is decreasing. However, these studies are limited to ages 15 years and over.

Methods

This study integrates sports club membership data from five popular team sports and investigates sport participation across the lifespan (4–100 years) by sex and region (metropolitan/non-metropolitan).

Results

Overall participant numbers per annum increased from 414,167 in 2010 to 465,403 in 2012 corresponding to a rise in the proportion of Victorian’s participating in these sports from 7.5 % in 2010 to 8.3 % in 2012. The highest proportion of participants was in the 10–14 year age range, with participation rates of 36 % in 2010 and 40 % in 2012. There was a considerably lower participation rate in the 15–19 year age group compared to the 10–14 age group, in all three years studied, and the decline continued progressively with increasing age. Male and female age profiles of participation were generally similar in shape, but the female peak at age 10–14 was sharper than for the males, and conversely there were very few 4 year old female participants. Participation rates were generally higher in non-metropolitan than metropolitan areas; the difference increased with increasing age from 4 to 34 years, then steadily declined, reaching parity at around 60 years of age.

Conclusions

It is a positive sign that participation in these popular sports increased by over 50,000 participants from 2010 to 2012. Large proportions of the population aged 5–14 participate in club based sport. Participation rates decline sharply in late adolescence, particularly for females, and while this may not be a concern from a broad health perspective so long as they transition into other forms of physical activity, it is certainly a matter of concern for the sport sector. It is recommended that sport policy places a higher priority on grass-roots participation and that sporting organisations are supported to prioritise the retention issues occurring during adolescence, particularly for females so as to maximise the potential for sport to maintain its positive contribution to population wellbeing.

Changes in sport and physical activity participation for adolescent females: a longitudinal study

BACKGROUND

Participation in sport and physical activity is reported to decline during adolescence, particularly for females. However we do not have a clear understanding of changes in the context (i.e., modes and settings) of participation throughout adolescence. This study investigated longitudinal changes in physical activity participation and the specific modes and settings of physical activity, together with cross-sectional comparisons, for two age cohorts of female adolescents.

METHODS

Survey of 729 adolescent girls (489 recruited in Year 7 and 243 in Year 11). Participation in eight different modes/settings was reported. PA was measured using 24-h recall diary and metabolic equivalent weighted energy expenditure (MET-min) in Leisure Time Moderate and Vigorous Physical Activity (LTMVPA) on the previous day was calculated.

RESULTS

There were no significant changes in duration or total MET-min of LTMVPA on previous day. However, there were significant changes in the modes/settings of participation across time. Participation in school physical education rose during early adolescence before decreasing significantly, and participation in competitive sport and club sport significantly decreased over time; however there were increases in non-competitive forms of physical activity.

CONCLUSIONS

Overall levels of physical activity did not significantly decrease over adolescence, which is positive for physical health. However, the transition from structured sport to non-organised physical activity may effect social and psychological health, which needs to be further examined.

Number of years of participation in some, but not all, types of physical activity during adolescence predicts level of physical activity in adulthood: Results from a 13-year study

Background

Adolescent physical activity (PA) levels track into adulthood. However it is not known if type of PA participated in during adolescence is associated with PA levels later in life. We aimed to identify natural groupings of types of PA and to assess whether number of years participating in these different groupings during adolescence is related to PA level in early adulthood.

Methods

673 adolescents in Montreal, Canada, age 12–13 years at baseline (54 % female), reported participation in 29 physical activities every 3 months over 5 years (1999–2005). They also reported their PA level at age 24 years (2011–12). PA groupings among the 29 physical activities were identified using factor analysis. The association between number of years participating in each grouping during adolescence and PA level at age 24 was estimated using linear regression within a general estimating equation framework.

Results

Three PA groupings were identified: “sports”, “fitness and dance”, and “running”. There was a positive linear relationship between number of years participating in sports and running in adolescence and PA level at age 24 years (β (95 % confidence interval) = 0.09 (0.04-0.15); 0.08 (0.01-0.15), respectively). There was no relationship between fitness and dance in adolescence and PA level at age 24.

Conclusions

The association between PA participation in adolescence and PA levels in young adulthood may be specific to certain PA types and to consistency of participation during adolescence. Results suggest that efforts to establish the habit of participation in sports and running in adolescence may promote higher PA levels in adulthood.

Current perspectives on physical activity and exercise for youth with diabetes

Regular physical activity (PA) for youth with diabetes improves cardiorespiratory fitness, body composition, bone health, insulin sensitivity, and psychosocial well-being. However many youth with diabetes or pre-diabetes fail to meet minimum PA guidelines and a large percentage of youth with diabetes are overweight or obese. Active youth with type 1 diabetes tend to have lower HbA1c levels and reduced insulin needs, whereas activity in adolescents at-risk for type 2 diabetes improves various measures of metabolism and body composition. Insulin and nutrient adjustments for exercise in type 1 diabetes is complex because of varied responses to exercise type and because of the different times of day that exercise is performed. This review highlights the benefits of exercise and the established barriers to exercise participation in the pediatric diabetes population. A new exercise management algorithm for insulin and carbohydrate intake strategies for active youth with type 1 diabetes is presented.

Participation in sport and physical activity: associations with socio-economic status and geographical remoteness

Background

Many factors influence participation in sport and Physical Activity (PA). It is well established that socio-economic status (SES) is a critical factor. There is also growing evidence that there are differences in participation patterns according to residential location. However, little is known more specifically about the relationship of PA participation and frequency of participation in particular contexts, to SES and residential location. This study investigated the relationship of participation, and frequency and context of participation, to SES and location.

Methods

Three aspects of participation were investigated from data collected in the Exercise, Recreation and Sport Survey (ERASS) 2010 of persons aged 15+ years: any participation (yes, no), regular participation (<12 times per year, ≥12 times per year) and level of organisation of participation setting (non-organised, organised non-club setting, club setting).

Results

The rates of both any and regular PA participation increased as SES increased and decreased as remoteness increased. However, participation in PA was SES- or remoteness-prohibitive for only a few types of PA. As remoteness increased and SES decreased, participation in many team sports actually increased. For both SES and remoteness, there were more significant associations with overall participation, than with regular participation or participation in more organised contexts.

Conclusions

This study demonstrates the complexity of the associations between SES and location across different contexts of participation. Nevertheless, it seems that once initial engagement in PA is established, SES and remoteness are not critical determinants of the depth of engagement.
