TL;DR: The percentage of adolescents exposed to health risk behaviors was high, especially when simultaneous exposure to different behaviors was considered, and these results can contribute to developing health promotion campaigns for the school setting that are specifically aimed at the risk subgroups identified.

TL;DR: Data indicated that the regular participation in sports is positively associated with a higher frequency of physically active behaviors during leisure time, however, the results did not support the hypothesis that the engagement in sports necessarily decreases leisure time spent in TV viewing.

TL;DR: Individuals perceive health not only as the absence of a disease, but also as a construct related to social, demographic and, to a lesser extent, behavioral aspects that must recognize this fact and transcend the simplistic model where health is dichotomized into the sick and the non-sick.

TL;DR: The perception of barriers was associated with a higher prevalence of leisure-time physical inactivity in adolescents and should therefore be considered in actions for promoting physical activity in this population.

TL;DR: The most frequently reported barriers to PA among adolescents were lack of company, lack of social support from family and friends, unsuitable climate and limited access to spaces for PA as discussed by the authors.
