Abstract
The aim of this study was to verify the association between school environment and accumulated physical activity in Brazilian adolescents. This is a study with secondary data from sample 1, from the third edition of the National School Health Survey, a study carried out with 102.072 children and adolescents enrolled in the ninth school grade. Questions about characteristics of the school environment and the offer of opportunities for physical activity practices were addressed, focusing on information regarding the structure for physical activity and about the regular practice of accumulated physical activities. Variables were organized from the structure of schools and opportunities for the practice of physical activities, while accumulated physical activity was used as the outcome variable. Data were analyzed from a binary logistic regression model, organized in crude and adjusted models, with a significance level of 5%. Data were analyzed from SPSS for Windows, version 22.0. Results indicate that, from the adjustment of variables, there was an association between the practice of accumulated physical activity and the existence of a sports court under conditions of use (OR=1.22, 95%CI=1.18-1.26), or presence of courtyard for use of physical education classes (OR=1.04, 95%CI=1.01-1.06). Association between the offer of varied physical activities, except for physical education classes, and the practice of accumulated physical activity (OR=1.05, 95%CI=1.02-1.08) was identified. Existence of a sports court/courtyard in schools and the offer of extracurricular physical activities are associated with the practice of accumulated physical activity in young Brazilian students.
Highlights
Several studies[1-3] and official documents[4,5] have pointed to the high prevalence of low levels of physical activity in children and adolescents, especially surveys with the school space as a reference.The WHO4 recommends that children and adolescents accumulate at least 60 minutes in physical activity practices of moderate intensity daily as a way of promoting health and preventing diseases and adopting an active behavior[4,6]
According to the latest PeNSE data[5], physical activity among Brazilian adolescents is estimated in only 34.4%, which indicates the need for scenarios that favor the adoption of habits for the regular practice of physical activity in and out of school
Those directly related to the adoption of habits that lead to the regular practice of physical activities stand out, highlighting some interventions focused on the active commuting to school, the presence of physical education classes, practice, and participation in school competitions and games, recreation activities, among others[10,11]
Summary
Several studies[1-3] and official documents[4,5] have pointed to the high prevalence of low levels of physical activity in children and adolescents, especially surveys with the school space as a reference. Similar studies[8,9] have pointed to the importance of the school environment as the place where some behaviors, in children and adolescents, can be learned, especially due to the daily time that these individuals spend in this space Among these behaviors, those directly related to the adoption of habits that lead to the regular practice of physical activities stand out, highlighting some interventions focused on the active commuting to school, the presence of physical education classes, practice, and participation in school competitions and games, recreation activities, among others[10,11]. This study aims to identify and discuss the factors that are present in the school environment that influence or could influence the adoption of habits for the regular practice of physical activities in children and adolescents
