What is the contribution of each physical activity domain to total physical activity in adolescents?

Abstract The present study aimed to verify the contribution of different physical activity domains to “ total physical activity ” in Brazilian adolescents. This is a cross-sectional study using secondary data from the third edition of the National School Health Survey - PeNSE, 2015. The sample consisted of 100,497 adolescents of both sexes enrolled in the 9th grade of elementary schools. A linear regression model was used to verify how much each domain contributed to total physical activity, considering gender, type of municipality and region. The domain with the largest contribution to “ total physical activity ” regardless of sociodemographic and environmental variables was “ extra-school physical activity ” (R2 = 0.60), followed by “ active commuting ” (R2 = 0.34), and finally “ Physical Education classes ” (R2 = 0.23). The contribution of the different domains varied by gender, type of municipality and region, and it was concluded that “ extra-school physical activity ” make the greatest contribution to “ total physical activity ” , followed by “ active commuting ” and “ Physical Education classes ” . In addition, variation was observed in the contribution of domains by gender, type of municipality and region.Resumo O presente estudo teve como objetivo verificar a contribui ção dos diferentes domínios da atividade física na “ atividade f ísica total ” em adolescentes brasileiros.Trata-se de estudo transversal utilizando...
