Abstract | Objectives: To evaluate the effectiveness of a multi-component school-based intervention on physical activity (PA) and screen time (ST) among urban adolescents in Bangladesh. Design: Cluster-randomised controlled trial. Methods: Eight high schools were randomly assigned to either intervention group (IG) or control group (CG). Participants Results: Total PA (MET-min/week) was increased from baseline to 8 and 12 weeks in the IG (3%–5%) but decreased in the CG (5%–3%) and significantly improved in the IG compared to the CG (p < 0.001) over time. Average ST (min/day) reduced from baseline to 8 and 12 weeks in the IG (28%–35%), while remained unchanged in the CG (6%–5%). The IG had a significantly lower average ST than the CG at 12 weeks. The average knowledge scores on PA and SB were significantly higher in the IG than the CG at 12 weeks (p < 0.001). Conclusions: Our intervention has demonstrated some promising effects on increasing PA, reducing ST, and improving PA and SB knowledge. This study underscores the need for a scaled-up evaluation in other locations including |
