Objective:
To analyze the association between the Social Ecological Model and meeting the physical activity, sedentary behavior, and sleep recommendations in a combined and integrated manner among adolescents.
Methods:
This is a cross-sectional study conducted in public schools in the Metropolitan Region of Recife, state of Pernambuco, Brazil, with adolescents aged 14 to 17 years. An adapted version of the Global School-based Student Health Survey was used as the instrument. Robust Poisson regressions were performed.
Results:
Approximately 1.8% of the 576 adolescents met all three recommendations simultaneously. Enjoying physical activity (prevalence ratio [PR] 11.62; 95% confidence interval [CI] 1.50-89.75) was associated with the combined adherence to the physical activity and sedentary behavior recommendations. Having two or more friends (PR 0.38; 95%CI 0.18-0.76) and participating in one (PR 0.39; 95%CI 0.20-0.78) or two physical education classes per week (PR 0.43; 95%CI 0.20-0.92) were associated with lower probabilities of non-compliance with these recommendations. Self-rated sleep quality as good (PR 2.49; 95%CI 1.09-5.67) was associated with higher prevalence of meeting the combined recommendations for sedentary behavior and sleep. Being male (PR 0.48; 95%CI 0.23-0.97) and participating in one physical education class per week (PR 0.40; 95%CI 0.16- 0.99) were associated with lower prevalence of not meeting the recommendations for sedentary behavior and sleep. Self-reported sleep quality as good (PR 3.11; 95%CI 1.36-7.10) as well as being male (PR 2.10; 95%CI 1.14-3.87) were associated with a higher likelihood of meeting the combined recommendations for physical activity and sleep. Actively commuting to school (PR 0.48; 95%CI 0.27-0.83) was associated with a lower likelihood of not meeting these recommendations.
Conclusions:
Intrapersonal, interpersonal, and community factors are associated with adherence to physical activity, sedentary behavior, and sleep recommendations in adolescents.
