    Abstract:
    The scope of this study was to assess the association between parental supervision and sedentary behavior and physical inactivity among Brazilian adolescents. Data of 102,072 students attending 9th grade from public and private school gathered in the 2015 Brazilian National Survey of School Health (PeNSE) were used. Adolescents were sedentary and physical inactive when they spent ≥3 hours/day sitting and practiced less then 60min/day of physical activity, respectively. Frequency of parental supervision (never, sometimes, always) was assessed through checking school homework, knowledge about what the adolescents do in their free time and understanding their problems. Logistic regression was applied and duly adjusted for sociodemographic variables. Among the adolescents, 56.3% were sedentary and 78.1% were inactive. Checking school homework was associated with lower odds of physical inactivity and sedentary behavior. Knowing what adolescents did in their free time and inspecting their belongings was associated with lower odds of physical inactivity. The understanding of problems by parents/guardians was associated with lower odds of sedentary behavior. The conclusion drawn is that greater parental supervision is associated with less physical inactivity and less sedentary behavior. Avaliamos associações da supervisão parental com o comportamento sedentário e a inatividade física em adolescentes brasileiros. Utilizamos dados da Pesquisa Nacional de Saúde do Escolar (PeNSE) de 2015, que avaliou 102.072 escolares do 9° ano. Consideramos sedentários os adolescentes que ficavam ≥3 horas/dia sentados e inativos os que praticaram <60 min/dia de atividade física. A supervisão parental foi avaliada pela frequência (nunca, às vezes, sempre) de atividades com verificar o dever, saber sobre o tempo livre e entender os problemas do adolescente. Foram realizadas análises de regressão logística, ajustadas para variáveis sociodemográficas. Dentre os avaliados, 56,3% eram sedentários e 78,1% inativos. Verificar atividades escolares se associou à menor odds de inatividade e sedentarismo. Ter ciência do que o adolescente fazia no tempo livre e mexer nas coisas do adolescente se associaram a menor odds de inatividade física. A compreensão de problemas pelos responsáveis se associou à menor odds de sedentarismo. Concluímos que maior supervisão parental se associou a menor sedentarismo e menor inatividade física entre adolescentes.
