Perception of the social and built environment and physical activity among Northeastern Brazil adolescents.

TL;DR: The results of a moderation analysis suggest that the beneficial effects of physical activity and social cohesion on mental health are strengthened by a perception of neighborhood safety, which is also confirmed by the results of multilevel regression models.

TL;DR: In this paper, the authors used qualitative walk-along interviews to determine which social and physical environmental factors affect adolescents' visitation and physical activity in public open spaces (POS) in low-income neighbourhoods.

TL;DR: The prevalence of IPA is high among adolescents and that the definition adopted in this study is rarely used in the literature, suggesting that it is necessary the development of interventions for increasing physical activity levels among adolescents.

TL;DR: The estimates of these risk behaviors among Brazilians adolescents were very close to or even greater than those found in developed countries in several studies analyzed in this review.

TL;DR: Neighborhood environment was associated with physical activity and overweight prevalence and the reliability and validity of self-reported neighborhood environment subscales were supported.

TL;DR: Results highlight links between the physical environment and children's physical activity and suggest additional research using a transdisciplinary approach and assessing moderating and mediating variables is necessary to appropriately inform policy efforts.

TL;DR: Most consistent positive correlates of PA were father's PA, time spent outdoors and school PA‐related policies, and support from significant others, mother’s education level, family income, and non‐vocational school attendance (in adolescents).

TL;DR: The vast majority of adolescents do not achieve five or more bouts of moderate physical activity per week, and continue to fail to achieve this amount of activity into adulthood.
