Participation frequency in physical education classes and physical activity and sitting time in Brazilian adolescents.

ABSTRACT: INTRODUCTION:To examine the association between participation frequency per week in physical education (PE) classes and physical activity (PA) and sitting time levels in adolescents according to the economic development level of the region of residence. METHODS:A cross-sectional study with a sample representative of Brazil was carried out with 12,220 students aged 11-19 years. Participation frequency per week in PE classes, moderate-to-vigorous PA (MVPA), PA during PE classes, active commuting, PA outside of school hours, total accumulated PA, time sitting in front of the TV and total sitting time were assessed by using a self-administered questionnaire. RESULTS:Adolescents who reported having PE classes were more likely to meet MVPA recommendations (1-2 PE class/week-OR: 1.3, 95%CI: 1.1-1.5; ?3 PE class/week-OR: 2.0, 95%CI: 1.7-2.5), spent more time in PA outside of school hours (1-2 PE class/week-OR: 1.6, 95%CI: 1.4-1.9; ?3 PE class/week-OR: 2.0, 95%CI: 1.5-2.6), and accumulated more PA (1-2 PE class/week-OR: 1.9, 95%CI: 1.6-2.2; ?3 PE class/week-OR: 6.0, 95%CI: 4.0-8.9) than students who reported not taking PE classes. Boys from regions with higher Human Development Index (HDI) who took ?3 PE classes/week were more likely to have higher levels of active commuting (OR: 1.4, 95%CI: 1.1-1.9) and less likely of getting in front of TV (OR: 0.7, 95%CI: 0.5-0.9). Adolescents from regions with higher HDI were more likely to have more time spent in PA during PE classes (Male-OR: 2.7, 95%CI: 2.4-3.1; Female-OR = 3.2, 95%CI: 2.8-3.7). CONCLUSIONS:Having PE classes is associated with a higher level of PA in both sexes and in both regions and lower level of sitting time in boys from regions with higher HDI.

Project description:BackgroundThe aim of this study was to determine whether engagement in more physical education (PE) classes during one high school year is associated with change in physical activity (PA) from adolescence to young adulthood.MethodsData were from 1774 participants in Waves 2 (high school, 1996) and 4 (young adulthood, 2008) of the National Longitudinal Study of Adolescent to Adult Health. The predictor was number of PE classes/week in high school (daily, some, or none). The outcome was change in moderate-to-vigorous physical activity (ΔMVPA) over the 12-year period. ΔMVPA was based on differences in MVPA scores derived at each wave from responses to a physical activity behavior recall (range, -9 to 9 scale score or -15 to 15 MVPA episodes/week). Multivariable generalized linear models examined the association between PE participation and ΔMVPA, adjusting for sociodemographics, weight status, and school clustering.ResultsIn high school, 34.7% participated in daily PE, whereas 50.1% participated in none. Participation in more PE classes was associated with greater MVPA in high school (mean MVPAW2none = 3.11, standard deviation [SD] = 1.99; mean MVPAW2some = 3.70, SD = 2.00; mean MVPAW2daily = 4.31, SD = 1.95; p < 0.0001). Overall, MVPA decreased over the 12 years (median ΔMVPA = -1.0, or 1-2 MVPA episodes/week). MVPA decreased more for males (median ΔMVPAmale = -1.0, interquartile range [IQR] = -3.0 ± 1.0; median ΔMVPAfemale = 0.0, IQR = -2.0 ± 2.0; p < 0.0001) and those who had participated in some/daily PE (median ΔMVPAsome = -1.0, IQR = -3.0 ± 1.0; median ΔMVPAdaily = -1.0, IQR = -3.0 ± 1.0) than those not in PE (median ΔMVPAnone = 0.0, IQR = -2.0 ± 2.0; p < 0.0001). The relationship between PE and ΔMVPA was maintained in multivariable analyses (βsome = -0.58, standard error [SE] = 0.18; p = 0.002; βdaily = -0.93, SE = 0.16; p < 0.001).ConclusionsHigh school PE participation did not prevent declining PA from adolescence to young adulthood.

Project description:ObjectivesTo investigate the associations between physical activity pattern, sports participation, screen time and mental health in Swedish adolescents.Design, setting and participantsA total of 1139 Swedish adolescents (mean age 13.4) from 34 schools participated in the cross-sectional study 'Physical Activity for Healthy Brain Functions in School Youth' in 2019.MethodsTime spent sedentary and in moderate-to-vigorous physical activity (MVPA) was measured using accelerometers for seven consecutive days. Screen time and sports participation were self-reported. Anxiety and health-related quality of life (HRQoL) were assessed using a Short version of the Spence Children's Anxiety Scale and Kidscreen-10.ResultsMVPA was positively associated (95% CI 0.01 to 0.05 in girls and 0.02 to 0.07 in boys) whereas screen time on weekdays was inversely associated with HRQoL (-4.79 to -2.22 in girls and -2.66 to -0.41 in boys). The largest effect sizes were observed between the high/low MVPA group in boys (Cohen's d=0.51) and screen time groups in girls (Cohen's d=0.59 on weekdays). With regards to anxiety, high compared with lower time spent in MVPA during leisure time on weekdays was associated with lower anxiety scores (95% CI -0.13 to -0.05 in girls and -0.07 to -0.01 in boys). Gender differences were observed, boys who participated in organised sports had low anxiety scores (95% CI -3.49 to -0.13) whereas girls who reported 5 hours or more of screen time had high scores (95% CI 1.94 to 6.18 on weekdays and 1.39 to 5.29 on weekend days).ConclusionsThis study showed that MVPA was associated with better mental health, whereas the opposite was seen for screen time. These associations were not consistently significant throughout all time domains, between the genders and mental health outcomes. Our results could create a paradigm for future studies to decide which types of PA patterns and time domains to target in intervention studies with the aim improve mental health among adolescents.
