The present study sought to examine the associations between participation in physical education (PE) classes and a range of health-related behaviours among adolescents. Secondary analysis of self-reported data from the Global Student Health Survey, collected between 2010 and 2017 from 222,121 adolescents (N = 117,914 girls; 49.0%; aged 13–17 years) from 67 countries and five world regions, was carried out. Participation in PE classes (0, 1–2, ≥3 days/week) was the independent variable. Physical activity (PA); sedentary behaviour (SB); active travel to school; fruit, vegetables, and alcohol consumption; and smoking; as well as adopting ≥5 of these healthy behaviours; were the dependent variables. Complex samples logistic regressions were performed to explore the associations between participation in PE classes and health-related behaviours. The results revealed that 18.2% of adolescents did not take part in PE classes. A total of 56.7% and 25.1% of adolescents reported participating in PE classes on 1–2 and ≥3 days/week, respectively. Only 26.8% of adolescents adopted ≥5 healthy behaviours. Participation in PE classes was positively associated with PA, active travel, fruit consumption, and vegetable consumption (only for ≥3 days/week), but was negatively associated with meeting SB recommendations, and with not smoking (only for girls and ≥3 days/week). Overall, PE participation was positively associated with adopting ≥5 healthy behaviours, with favourable results found for those who attended more PE classes. The findings revealed a positive association between participation in PE classes and a range of health-related behaviours among adolescents. This suggests that, worldwide, quality PE should be delivered at least 3 days per week up to daily to promote healthy lifestyles among adolescents.

Children’s motor competence (MC) levels tend to be low, and the investigation of variables that facilitate skillfulness is an important concern. The socioecological model is a useful framework to explore factors that influence MC and to inform the development of targeted interventions. This cross-sectional study aimed to perform an exploratory analysis of MC correlates among children. The sample comprised 267 second- and fourth-grade children (120 female; Mage = 102 months, SD = 14 months) from six primary schools. The children’s legal guardian questionnaire collected sociodemographic, behavioral, and family variables. MC was assessed with the Motorische Basiskompetenzen battery. Data analysis involved simple and multiple regression models. The mean total Motorische Basiskompetenzen score was 8.9 (3.4) out of a maximum score of 16. Sex, age, body mass index, and physical activity and sports clubs were significantly related to total MC in all models (p < .05). The final model predicted a variance of 24.5%, adjusted R2 = .245, F(20, 246) = 5.32, p < .001, with male sex (B = 2.03) and organized physical activity (B = 0.35) being positively associated with total MC. Fourth grade (B = −3.6) and body mass index (B = −0.23) were negatively associated with MC. The study provides provisional evidence for the role of some sociodemographic and behavioral factors in MC development, which are important to design future MC interventions.
