In the past several years, schools have emerged as an important location for addressing childhood obesity given the large number of young people who regularly access this setting. There is also growing awareness that school policies and environmental interventions have the potential to promote healthy physical activity (PA) habits in schools (1, 2). This brief summarizes the impact of school PA-related policies and interventions on student PA levels, sedentary behaviours, and body weight outcomes.
- School PA-related policies and interventions may be effective in increasing student PA levels, though additional research and evaluation is required, particularly at the public policy level (3, 7).
- Evidence of the impact of school physical activity related policies and interventions is limited for sedentary behaviours, and mixed for BMI and weight outcomes (4, 5, 8, 9).
- Broad, multi-component interventions may hold the most promise for promoting healthy weights (3-6).
