Supervisão parental e inatividade física em adolescentes brasileiros

Abstract

We aimed to assess the association between parental supervision and physical inactivity among Brazilian adolescents. We used data from the Brazilian National Survey of School Health (PeNSE) 2015, with 102,072 students attending 9th grade from public and private school. We classified adolescents as physical inactive if they have practiced less than 420 min/ week of physical activity. Parental supervision was assessed by the frequency (never, sometimes, always) of activities such as checking school activities, knowing about free time, understanding problems, and tinkering with the teenager's belongings. The associations were verified through logistic regression, adjusted for sociodemographic characteristics and relatives. Of the adolescents evaluated, 78.1% were inactive. Adolescents whose parents always check their school activities (OR=0.70;IC95%=0.65-0.76), were always aware of what they did in free time (OR=0.83;IC95%=0.75-0.91), tinkers with their belongings (OR=0.78;IC95%=0.72-0.84), always missing classes without parental permission (OR=0.64;IC95%= 0.52–0.78) and had mothers with higher schooling (O.R.=0.82;IC95%=0.75-0.90) were less likely to be inactive. We concluded that greater parental supervision is associated with less physical inactivity.
