Assess graduate-level ability to critically evaluate school-based physical activity interventions for adolescent obesity prevention, focusing on methodological rigor (study design, measurement validity, bias, statistical analysis), equity outcomes (distributional impacts, subgroup analyses, social determinants, access barriers), and policy implications (scalability, cost-effectiveness, implementation fidelity, ethical and regulatory considerations). Test skills in appraising evidence quality, synthesizing heterogeneous findings, identifying equity gaps, and formulating policy recommendations grounded in rigorous research appraisal.
