Effect of a school-based multicomponent intervention on time-segmented physical activity and sedentary behavior among adolescents: a cluster randomized control trial.

ABSTRACT:

Background

Interventions have focused on evaluating effective strategies for increasing physical activity (PA) and reducing sedentary behavior (SB) in children and adolescents, which is still a challenge mainly in low- and middle-income countries. Thus, this study aimed to assess the effect of the Movimente Study on device-measured PA and SB in two-time segments of the school day amongst Brazilian adolescents.

Methods

Six elementary schools were randomized into the intervention (IG) or control group (CG). Participants were in 7th -9th grades. A school year (2017) multicomponent intervention was delivered consisting of three components: (1) teacher training, (2) education curriculum, and (3) school environment. PA and SB were assessed using GT3x + ActiGraph hip-worn accelerom
