Abstract
Less than half of adolescents reach the recommended300 minutes per week of physical activity (PA). Physical educationclasses and sports participation provideopportunities for adolescents to accumulate moretime for PA practice; however, littleis known about the influence of these variables onthe level of total physical activity ofadolescents. The aim of this study was toinvestigate the association between the practiceof physical education (PE) in schools and sportsactivities (SA) with the practice oftotal PA of adolescents. The study wascross-sectional and involved 467 adolescents ofhigh school (15.8 ± 0.9 years-old) from the city ofRio Claro, in the State of São Paulo. Participants completed the Physical ActivityQuestionnaire to Older Children (PAQ-C)and questions related to the practice of PE and SAin schools. We performed a logisticregression with p<0.05 using SPSS. Girls hadlower prevalence of PA than boys, 9.4% and26.8%, respectively. Boys who did not participateof PE classes (OR=0.25, CI95%=0.09-0.66) and SA in schools (OR=0.34, CI95%=0.12-0.95)were less likely to be active in PAthan boys who practiced these activities. Theparticipation in PE classes or engagementin some SA were positively associated with thepractice of total PA in boys.
Highlights
The regular practice of physical activity (PA) in adolescence may contribute to a healthy lifestyle both in this period and in adulthood, reducing the incidence of noncommunicable diseases[1,2,3]
The third was replaced by another private school, the school refused to participate in the study
As all schools in Rio Claro (19) were already joining the work, it was decided to select another school that was already participating in the study and, a new class was raffled
Summary
The regular practice of physical activity (PA) in adolescence may contribute to a healthy lifestyle both in this period and in adulthood, reducing the incidence of noncommunicable diseases[1,2,3]. The enough practice of PA, in adolescence, is associated with the weight loss, the improvement in metabolic parameters, lowering blood pressure and insulin resistance, as well as the psychological well-being, the predisposition to maintain PA during adulthood, the decreased risk for cardiovascular disease and, an increase in life expectancy[1,2]. Despite this evidence, the prevalence of PA among adolescents is very low. Physical education (PE) classes and participation in sports activities (SA) that are held inside schools contribute to adolescents accumulate more PA practice time[7,8]
