RESUMEN

BACKGROUND: Interpersonal Violence (IV) against children in sports is a prevalent problem and has a major impact on their well-being. However, the causal relationship and the costs for society remain unclear. OBJECTIVE: The aim of this study is to estimate the causal effect of severe IV in sports on Subjective Well-Being (SWB) and to monetize the collective loss for society. PARTICIPANTS AND SETTING: The study used survey data from 4003 respondents in the Netherlands and Flanders (Belgium). The questionnaire included current SWB as well as 41 items to assess experiences with psychological, physical and sexual IV in sports before the age of 18. Severity was quantified by experts and reported frequency. METHODS: By using the number of sports that someone participated in during their youth as an instrumental variable to control for confounding, the study estimates the causal effect of severe IV on SWB. The Three-Stage Well-Being Valuation Approach was used to monetize the loss in SWB in terms of income compensation. RESULTS: The results show that experiencing severe IV in sports results in significant lower SWB levels (b = -0.45, p < .01). The lower SWB is comparable to an annual loss of income of 9672 euro per person. CONCLUSIONS: We have found evidence for a causal effect of severe IV in childhood on the SWB later in life. The results highlight the long-term, extensive impact of experiencing severe IV in sports that exceeds direct physical and psychological health outcomes.

RESUMEN

The correlation between early attrition and school sports clubs has been underexplored. This study aims to clarify the correlates of early attrition from school sports clubs at a private male senior high school in Fukuoka Prefecture, Japan. Of the 928 first-year students, 331 belonging to the school's sports clubs were included in this study. A baseline survey was conducted in May 2017 and a follow-up survey was conducted in October 2019. This study defined early attrition as a student who quit a sports club earlier than April in their third year. Examined correlates for early attrition consisted of biological, intrapersonal, interpersonal, and institutional factors. We used univariate logistic regression analysis, in which early attrition was the response variable and the examined correlates were the explanatory variables, and calculated the odds ratios (OR) and 95% confidence intervals (CI). Overall, 232 students (85.0%) continued to participate in sports clubs after April of their third year, and 41 students (15.0%) experienced early attrition. Statistically significant correlates for early attrition were weight (OR = 0.94, 95% CI = 0.90-0.98), body mass index (OR = 0.84, 95% CI = 0.74-0.97), experience of injury or disability (OR = 0.40, 95% CI = 0.19-0.87), athletic achievement (OR = 0.29, 95% CI = 0.13-0.62), and duration of experience of the sport (OR = 0.99, 95% CI = 0.98-1.00). Our findings suggest that the school officers or family members of students should recognize the possibility of early attrition and provide appropriate support if a student experiences early attrition. The athletic level or norms of school sports club activities may differ among other schools and sports clubs; therefore, it is necessary to examine whether our findings are applicable to other schools and sports clubs.

RESUMEN

Purpose: Given that previous research on relative age effects (RAEs) has only focused on organized sport, the aim of this exploratory study was to examine whether this phenomenon also existed among self-organized practitioners. In relation to that, a second aim was to know whether self-organized sport practices could be favored by late-born practitioners as a result of a strategic adaptation. Method(s): Representative sub-samples of 474 soccer players, 363 basketball players, 2,536 swimmers, 1,788 strength training practitioners, 1,873 pétanque players, 973 table tennis players and 2,136 runners were analyzed. Results: The results did not show any significant RAEs, including in sport practices that are sensitive to this phenomenon such as soccer or basketball. The results did not show any significant overrepresentation of late-born people either. Conclusion: This study suggests that self-organized sport practices are not impacted by the RAEs. This finding is interesting because self-organized sport practice is the most important one in numbers.

RESUMEN

BACKGROUND: Health benefits have been linked with physical activity (PA), as well as some domains of PA among youth (e.g. organized PA and active transport). However, less is known about whether some PA domains are more beneficial than others. There is also a lack of evidence about whether health outcomes are related to the composition of PA (i.e. the share of PA spent in different domains). This study aimed to identify: (1) how the absolute durations of organized PA, non-organized PA, active transport and active chores/work at 10-11y are individually associated with physical, psychosocial and total health-related quality of life (HRQOL) at 10-11y and 12-13y; and (2) how the domain-specific composition of PA at 10-11y is associated with HRQOL at 10-11y and 12-13y. METHODS: Data from the Longitudinal Study of Australian Children were used in cross-sectional (n ≥ 2730) and longitudinal analyses (n ≥ 2376). Measurement included the Pediatric Quality of Life Inventory (PedsQL™) for HRQOL domains and one-day time-use diaries (TUDs) for PA domains. Robust linear regression models were used, controlling for age, sex, pubertal status, socioeconomic position, body mass index and TUD context (season and school attendance). Compositional models additionally adjusted for total PA duration and longitudinal models controlled for baseline PedsQL™ scores. RESULTS: Non-compositional models indicated that the duration of organized PA, and to a lesser extent non-organized PA, were positively but weakly associated with some HRQOL outcomes at 10-11y. These trends were not reflected in longitudinal models, although a 30-min increase in non-organized PA per day did predict marginally better psychosocial HRQOL at 12-13y (+ 0.17%; 95%CI = + 0.03%, + 0.32%). Compositional models revealed that a 30-min increase in organized PA relative to other domains was positively but weakly associated with physical (+ 0.32%; 95%CI = + 0.01%, + 0.63%), psychosocial (+ 0.41%; 95%CI = + 0.11%, + 0.72%) and total HRQOL (+ 0.39%; 95%CI = + 0.12%, + 0.66%) at 10-11y. However, the overall PA composition at 10-11y was not related to HRQOL at 12-13y. CONCLUSIONS: Non-compositional and compositional models generally concurred on the direction of cross-sectional and longitudinal relationships (and lack thereof) between PA domains and HRQOL outcomes. The strongest associations were cross-sectional between organized PA and HRQOL at 10-11y. However, all associations between PA domains and HRQOL outcomes were weak and may not be clinically meaningful.

RESUMEN

The aim of this paper was to analyse the trends in the participation of Czech adolescents in organized sport activities in relation to the socioeconomic status (SES) of their families. The sample consisted of 11, 13 and 15-year-old children (N = 4425 (2010), 10,361 (2014) and 13,377 (2018)); the data were collected as part of the HBSC Study in the Czech Republic. The findings suggest that adolescents from affluent families tend to participate more often in organized sports-both team activities and individual activities. Fifteen-year-old adolescents from families with a high SES are 3.01 times more likely to participate in individual organized sports than adolescents from low-SES families. The gap between participation in sport activities increases with the children's age but does not change significantly during the observed period. The findings suggest that public health policy should be oriented towards children from less-affluent families.

RESUMEN

BACKGROUND: Physical activity (PA) declines during childhood. Important sources of PA are active travel, organised sport and physical education (PE), but it is unclear how these domain-specific PA sources contribute to (changes in) daily moderate-to-vigorous PA (MVPA) in young people. This study aimed to examine (1) the cross-sectional association between domain-specific physical activity (i.e., active travel, organised sport and PE) and daily minutes in accelerometer-assessed MVPA; and (2) the longitudinal association between domain-specific physical activity at baseline and change in daily minutes in MVPA. METHODS: Participants (baseline age 11.3 ± .1.2 years) were drawn from three studies in the International Children's Accelerometry Database. The contribution of self-reported standardised active travel, organised sport and PE to accelerometer-measured daily minutes in MVPA was examined using linear regression. In cross-sectional analyses, MVPA was regressed on each PA domain in separate models, adjusted for study, age, sex, maternal education, season, and monitor wear time. In longitudinal analyses, change in MVPA was regressed on each of the baseline PA domains, additionally adjusting for changes in season and wear time, follow-up duration, and baseline MVPA. R-squared was used to compare variance explained by each PA domain. RESULTS: In the cross-sectional analyses (n = 3871), organised sport (standardised ß = 3.81, 95% confidence interval [95%CI] = 3.06, 4.56) and active travel (ß = 3.46, 95%CI = 2.73, 4.19) contributed more to daily MVPA than PE (ß = 0.82, 95%CI = -0.02, 1.66). Compared to the base model which included only covariates (R2 = 21.5%), organised sport (absolute change: + 1.9%) and active travel (+ 1.7%) models explained more of the variance than the PE model (± < 0.1%). Associations followed a similar pattern in the longitudinal analyses (n = 2302), but none of the PA domains predicted change in MVPA (organised sport: standardised ß = 0.85, 95%CI = -0.03, 1.72; active travel: ß = 0.68, 95%CI = -0.14, 1.50; PE: ß = 0.02, 95%CI = -0.87, 0.91). CONCLUSIONS: A multi-sectoral approach covering a wide range of PA domains should be promoted to minimise the age-related decline in MVPA during childhood.

RESUMEN

This three-part investigation conducted a comprehensive analysis of 213 Australian and Canadian athletes' developmental trajectories, training histories, and experiences in organized sports from 18 Paralympic sports (PS). While athletes with early-onset impairments (i.e., congenital, preadolescent) reached milestones and commenced various types of training at a significantly younger age than athletes with later-onset impairments (i.e., early adulthood, adulthood), the latter groups progressed through their careers and incorporated various trainings at a faster pace (i.e., fewer years). Preferences to certain training conditions varied between groups. Eighty-two percent of the athletes with acquired impairments had experience in able-bodied sports before the onset of their impairment, with 70% noting involvement in sports similar to their current PS. The participation rates (38%) and sport similarity (53%) were lower in PS. The amalgamation of findings from this series of studies highlights the complexity associated with PS athletes' development and demonstrates the importance of taking an individualized approach.

RESUMEN

PURPOSE: Meaningful participation is related to satisfaction of the psychological needs of competence, autonomy, and relatedness within Self-determination theory. The purpose of this study is to explore whether need satisfaction in physical education (PE), organized sport, and self-organized physical activity (PA) among adolescents with disability differs in relation to their peers without disabilities over a three-year period. METHODS: Participants were students of secondary or upper secondary school (T1: N = 2979), reporting either having a disability (n = 328) or not (n = 2651). The psychological needs were measured in the three PA contexts over three time-points. Differences between groups were assessed with t-tests and Cohen's d. RESULTS: Adolescents with disability reported: in PE, lower need satisfaction across all three time-points; in organized sport, lower levels on all needs at T1, and lower levels of autonomy and relatedness at T2; in self-organized PA, no differences between the groups across all three time points, except for lower autonomy at T2. CONCLUSIONS: The findings indicate that adolescents with disabilities are particularly vulnerable to reduced participation in PE and partly in organized sport. Rehabilitation institutions should collaborate closely with stakeholders in PA (e.g., PE teachers and coaches) in adolescents' municipalities to transfer knowledge about nurturing psychological needs in PA.Implications for rehabilitationMeaningful participation in physical activity (PA) for the individual can be related to their own perceptions of satisfaction of the three basic psychological needs of competence, autonomy, and relatedness.Findings from the current study indicate that adolescents with disabilities are particularly vulnerable to experiencing reduced participation in physical education (PE) and partly in organized sport.Health care practitioners working in rehabilitation should support adolescents' three psychological needs in PA while they are attending rehabilitation to give them valuable experiences with meaningful participation in PA, which could be transferred and useful for PA participation after rehabilitation.Health care practitioners at rehabilitation institutions should collaborate closely with stakeholders in the PA context of adolescents' local areas (e.g., PE teachers and coaches) to transfer knowledge about how to nurture psychological need fulfillment in PA.

RESUMEN

Background: Organized sport participation (OSP) is considered as one method with the potential to increase overall physical activity (PA) levels in young people. It is essential to understand the correlates of OSP to inform future PA interventions. Purpose: This study aimed to explore the sociodemographic correlates of OSP among middle school students from the Nanjing City of China. Methods: A total of 7,097 adolescents (50.1% girls) aged 12-15 years from Nanjing, China, were recruited in this survey. Self-reported data on sex, grade, race, residence areas, proficient sport skills, and parental highest education were obtained. OSP was assessed by the question asked in the questionnaire on whether participants were involved in any "sports club or team" with the binary answer options of "yes" and "no," for statistical analysis purposes. Generalized linear models were used to determine the correlates of OSP. Results: Only 16.6% reported participating in any organized sport over the past whole year, while boys (OR = 1.34, 95% CI: 1.18-1.53) and 7th graders (OR = 1.40, 95% CI: 1.18-1.65) were more likely to participate in organized sport. Adolescents being Han ethnicity were less likely to either participate in organized sport (OR = 0.60, 95% CI: 0.40-0.92), or masterless (one or two) proficient sport skills [OR (one) = 0.27, 95%CI: 0.20-0.37; OR (two) = 0.43, 95% CI: 0.36-0.50]. Besides, both residence area and parental highest education were not significantly associated with OSP among the participating adolescents. Conclusion: The current study confirmed that only one-sixth of adolescents participate in the organized sport over the past year. At-risk population subgroups include girls, older adolescents, being Han ethnicity, and those proficient in fewer sport skills. Sex, grades, race, and proficient sport skills were significant correlates of OSP. School, community, and families need to provide more resources and support for disadvantaged populations in OSP.

RESUMEN

Child disruptive behavior refers to ongoing patterns of disorganized, uncooperative, and defiant behavior. Sport involvement promotes positive child development. However, few longitudinal studies have tested the association between organized sport participation and the behavioral components of disruptive behavior. First, we aim to examine the link between inattentive, hyperactive, aggressive, and oppositional behavior at age 4 years and trajectories of organized sport participation from ages 6 to 10 years. Then, we compare children, according to trajectory membership, on outcome differences on these same behaviors at age 12 years. Data are from the Quebec Longitudinal Study of Child Development (N = 1492). Child behavior was assessed by questionnaires completed by mothers at age 4 years and teachers at age 12 years. Preschool child inattention as perceived by mothers, significantly reduced the odds of middle childhood organized sport participation by 7% (95% CI = 1.00-1.15). Low or inconsistent participation in organized sport was subsequently associated with increased inattention (d = 0.28) by the end of sixth grade. These findings are above and beyond individual and family characteristics and baseline behavior. No other associations were statistically significant. Inattentive children who participated less in organized sport showed a greater likelihood toward increases in attention deficit by the end of sixth grade. To improve engagement from these children, coaches and trainers should use strategies that support positive experiences such as developing a one-to-one alliance with the child, favoring social cooperation through team spirit, and focusing on the performance experience rather than the outcome of winning or losing.

RESUMEN

This study aimed to examine the association of different frequencies of organized sport participation (OSP) with physical activity, cardiorespiratory fitness, body composition, sleep, and screen time among adolescents. A cross-sectional study involving 315 16-year-old adolescents was conducted. OSP was self-reported, being categorized as 0 times a week, less than three times a week, 4-5 times a week, and 6-7 times a week, on average. Screen time was also self-reported but physical activity and sleep duration were objectively measured. Cardiorespiratory fitness and body composition were measured using a maximal cycle ergometer test and a dual-energy X-ray absorptiometry (DXA) scan, respectively. An analysis of covariance revealed a significant association between OSP and physical activity (F (3, 286) = 14.53, p < 0.01), cardiorespiratory fitness (F (3, 236) = 17.64, p < 0.01), screen time (F (3, 294) = 8.14, p < 0.01), body fat percentage (F (3, 292) = 11.84, p < 0.01), and fat free mass (F (3, 290) = 5.76, p < 0.01. No significant association was found between OSP and sleep duration. Post hoc analyses showed that OSP at least four times a week was beneficial to favorable physical activity levels, cardiorespiratory fitness, screen time, and body composition and may therefore serve as a valuable tool in battling unhealthy lifestyle behaviors among adolescents.

RESUMEN

BACKGROUND: There is an urgent need for scaled-up effective interventions which overcome barriers to health-enhancing physical activity for children and adolescents. In New South Wales (NSW), Australia, the state government implemented a universal voucher program, 'Active Kids' to support the cost of structured physical activity registration for school-enrolled children aged 4.5-18 years old. The objective of this study was to understand the effects a financial incentive intervention delivered in a real-world setting has on children and adolescent's physical activity participation. METHOD: In 2018, all children and adolescents registered for an Active Kids voucher provided sociodemographic characteristics, physical activity and research consent. This prospective cohort study used an online survey with validated items to measure physical activity and other personal and social factors in children and adolescents who used an Active Kids voucher. Generalized linear mixed models were used to examine changes from registration to after voucher use at ≤8 weeks, 9-26 weeks and ≥ 6 months. RESULTS: Study participants reported increasing their days achieving physical activity guidelines from 4.0 days per week (95%CI 3.8, 4.2) at registration (n = 37,626 children) to 4.9 days per week (95%CI 4.7, 5.1) after 6 months (n = 14,118 children). Increased physical activity was observed for all sociodemographic population groups. The voucher-specific activity contributed 42.4% (95%CI 39.3, 45.5) to the total time children participated in structured physical activities outside of school. Children and adolescents who increased to, or maintained, high levels of activity were socially supported to be active, had active parent/caregivers, had better concentration and were overall happier than their low-active counterparts. CONCLUSION: The Active Kids program significantly increased children's physical activity levels and these increases continued over a six-month period. The Active Kids voucher program shows promise as a scaled-up intervention to increase children and adolescents' physical activity participation. TRIAL REGISTRATION: Australian New Zealand Clinical Trial Registry ACTRN12618000897268 , approved May 29th, 2018 - Retrospectively registered.

RESUMEN

The purpose of this study was to examine whether Colombian adolescents fulfill physical activity (PA) recommendations by type of day depending on several variables. A cross-sectional study was carried out on a sample of 2624 adolescents from Neiva (Colombia) using the Seven Day PA Recall and the Family Affluence Scale II self-reported questionnaires. Statistical analyses were performed to find any differences by gender, socioeconomic status, PA recommendations accomplishment, participation in organized and non-organized PA, parents' involvement in sport, and adolescents' academic achievement, and to determine the probability of complying with the PA guidelines. Only 12.3% of the participants met the PA recommendations on weekdays and weekends. Girls maintained their (in)active patterns during the week more than boys (84.4% vs. 70.7%, respectively), while more boys than girls changed them according to the type of day (25.3% vs. 19.6%). Participation in organized sports was the predictor variable with the highest probability of both boys and girls complying with the PA recommendations on weekdays. Non-organized activities were more likely to make girls more active on weekends. In conclusion, a wider offer of organized and non-competitive PA over the weekend and broader sports schedules should be provided to youth in Neiva.

RESUMEN

OBJECTIVE: To explore whether the associations between developmental delays in the first year of life and psychosocial outcomes in preschool children are affected by participation in organized sport. STUDY DESIGN: Data were obtained from the infant cohort of the Growing Up in Ireland project. Parents reported on child development (Ages and Stages Questionnaire) at age 1 year, psychosocial characteristics (Strengths and Difficulties Questionnaire) at ages 3 and 5 years, and engagement in organized sport at age 5 years. Data were analyzed using mixed models. RESULTS: At age 1 year, 15% of the cohort was classified as having developmental delays. These children exhibited more behavioral difficulties (0.55, ±0.27; mean difference, ±95% confidence limits [CL]) (P < .0001) and fewer prosocial behaviors (-0.54, ±0.11) (P < .0001) at age 3 years. For boys in this group, engagement in sport was associated with a significant decrease in behavioral difficulties between ages 3 and 5 years (-0.44, ±0.39) (P = .03). Compared with those classified as lacking regular engagement (ie, never engaging, or engaging <1 hour/week), the relative effect of sport on changes in behavioral difficulties for boys with developmental delays was statistically significant (0.70, ±0.59) (P = .02). Participation in sport was not associated with significant changes in behavioral difficulties for girls, or a significant change in prosocial behaviors for boys or girls. CONCLUSIONS: Regular participation in sport by boys could attenuate some of the behavioral difficulties associated with early development. Lack of opportunities for engaging in sport could negatively affect boys' behavioral regulation in the preschool period.

RESUMEN

Several studies indicate that participation in organized sport may result in higher physical activity levels among youth which are associated with high levels of cardiorespiratory fitness. However, no study has examined whether cardiorespiratory fitness (VO2peak) is associated with drop out from sport. The study was a 5-year longitudinal study which followed a sample of adolescents, with measures of cardiorespiratory fitness, weight and height between the age of 14 and 19 yrs. Self-reported data about participation in sport, active commuting and physical activity level were also included. Through logistic regression analyses we found a positive association between cardiorespiratory fitness at the age of 14 years and participation in organized sport at the age of 19. However, no significant associations were found between physical activity (PA) level, overweight, gender and active commuting to school at the age of 14, and participation in organized sport at the age of 19. We argue that a high level of cardiorespiratory fitness may increase the probability for experiencing high levels of enjoyment, competence and performance in sport, because sport participation requires a certain level of cardiorespiratory fitness. The findings indicates the importance of removing barriers, and to increase access and design of sport programs of interest to youth in the contexts in which they live, attract adolescents with different levels of ambition and abilities in sport. Further studies should include longitudinal studies among young children, and their drop out patterns from sport during adolescence.

RESUMEN

Active Kids is a government-led, universal voucher program that aims to reduce the cost of participation in structured physical activity for all school-enrolled children in New South Wales (NSW), Australia. As part of the Active Kids program evaluation, this cross-sectional study examined the Active Kids' program's reach to children in NSW and their physical activity behaviors, before voucher use. Demographic registration data from all children (4.5-18 years old) who registered for an Active Kids voucher in 2018 (n = 671,375) were compared with Census data. Binary and multinomial regression models assessed which correlates were associated with meeting physical activity guidelines and participation in the sessions of structured physical activity. The Active Kids program attracted more than half (53%) of all eligible children in NSW. Children who spoke a primary language other than English at home, were aged 15-18 years old, lived in the most disadvantaged areas, and girls, were less likely to register. Of the registered children, 70% had attended structured physical activity sessions at least once a week during the previous 12 months, whilst 19% achieved physical activity guidelines. Active Kids achieved substantial population reach and has the potential to improve children's physical activity behaviors.

RESUMEN

In recent years, the problem of bullying, existing in sport and arising in athletes' relationships, is increasingly emphasized. The aim of this research was to reveal the specificity of bullying in athletes' interrelationships by elaborating on causes of its emergence, nature of actions, and its consequences. To achieve the research aim, a qualitative research paradigm was chosen. The theoretical part of the research was prepared by applying the methods of scientific literature analysis and analogy. The empirical study involved seven organized sports athletes representing individual, duel, and team sports branches, belonging to the young adult age category. The survey was conducted using the semi-structured interview method. Data were analyzed employing the conceptual content analysis. Emic and etic perspectives were used for data processing. Research results revealed that the specificity of manifestation of bullying in sport unfolded through three generalized categories: intolerable perception of behavior, nature of bullying, and bipolarity of consequences. Every category was detailed by sub-categories, highlighting the nature, causes, and consequences of bullying accepted by athletes in the contexts of their emotional state and career. We found that the factors falling into these categories were interrelated and supplemented each other; therefore, they should be analyzed in a complex way, as bullying is determined not by some single factor but by the totality of them, functioning as a kind of well-established flawed tradition supported by the cultures of the sports organization and the sport.

RESUMEN

The objective of the study was to determine whether 1) the proportion of athletes with mental health diagnoses and 2) athlete motivations for playing differ between team sports and individual sports. We conducted a cross-sectional study of child and adolescent athletes assessed at a sports injury prevention center. We compared self-reported anxiety, depression, and reasons for participating in sports between athletes in individual sports (e.g. gymnastics, running, diving) and team sports (e.g. soccer, football, hockey). In addition, we categorized motivation for participating in sports as 1) for fun, with associated benefits of participation including, motives such as making friends and being part of a team or 2) for goal-oriented reasons with associated benefits of participation including motives such as obtaining scholarship or controlling weight. At the time of this analysis, 756 athletes between the ages of 6 and 18 years had undergone a sports injury prevention evaluation. Most athletes were White (85%) and there was a slight female predominance (56%). Of the total population, 8% reported suffering from anxiety or depression. A higher proportion of individual sport athletes reported anxiety or depression than team sport athletes (13% vs. 7%, p < 0.01). Individual sport athletes were more likely than athletes in team sports to play their sports for goal-oriented reasons, as opposed to for fun (30% vs. 21%, p < 0.05). Individual sport athletes are more likely to report anxiety and depression than team sport athletes. The mental health benefits of participation in organized sports may vary between individual sport athletes and those playing team sports.

RESUMEN

Although physical activity level (PAL) is positively correlated with adolescents' health, many adolescents do not fulfill recommendations for physical activity. This study examines the associations of organized sport and self-organized physical activity, with PAL among adolescents. Participants were 301 adolescents (12-13 year-olds). The adolescents wore accelerometers for 1 week according to international standards, and reported their participation in organized sport and self-organized physical activity in a questionnaire. The results showed that the level of participation in organized sport was positively associated with the adolescents' total PAL, while there was no significant association between time spent in self-organized physical activity and adolescents' daily minutes of moderate and vigorous physical activity. In addition, boys who participated <3 h per week (or not at all) in organized sport stood out with the lowest fulfillment of recommended PAL. Our findings underline the critical importance of getting adolescents, especially boys, to participate in organized sport and not to drop out from organized sport during adolescence.

RESUMEN

This study was to compare the levels of physical activity (PA) and sedentary behavior (SB) between Canadian and Guatemalan adolescents, and to examine associations of sociodemographic variables with PA and screen time among adolescents in Canada and Guatemala. Self-reported, cross-sectional data from students in grades 9-12 who participated in the 2015 COMPASS study (Canada; n = 39,817; mean age = 15.6 years) and COMPASS-Guatemala (n = 1,221; mean age = 15.1 years) were used. Sociodemographic variables included age, gender, ethnicity (exclusively among Canadians), and weekly money allowance. Outcome variables included meeting the PA guidelines (⩾60 minutes/day) and the screen time recommendations within the SB guidelines (<2 hours/day), and participation in organized sports in and out of school. Chi-squared tests and linear and logistic regressions were used to test the study objectives. The proportions of participants meeting the PA guidelines were 48.7% and 41.3% for Canadians and Guatemalans, respectively. More Guatemalan adolescents than Canadians met the screen time recommendations (24.9% vs. 16.5%). Older age, being male, being non-White, and $0-$5/unknown of allowance were associated with meeting the PA guidelines among Canadians. Gender (being male) was the only variable associated with meeting the PA guidelines among Guatemalan adolescents. Older age, being male, being non-White, and $0-$5/unknown of allowance were associated with organized sport participation among Canadians. Among Guatemalans, being aged 15-16 years and having 0-35 quetzals/unknown of allowance were associated with participating in competitive school sports. Being male was associated with participating in recreational school sports or league/team sports outside of school. Older age, being female, being non-White, and ⩾$6 of allowance were associated with meeting the screen time recommendations among Canadians. Older age and having ⩾150 quetzals of allowance were associated with meeting the screen time recommendations among Guatemalan adolescents. These findings can inform researchers and policy makers when developing country-specific targeted interventions and programs that promote physically active lifestyles.
