N2 - Objective: To inform Supplemental Nutrition Assistance Program Education (SNAP-Ed) and other school-based interventions aiming to improve youth cardiorespiratory fitness, this study aimed to identify which SNAP-Ed school-based physical activity intervention combinations were associated with better student cardiorespiratory fitness. Methods: This study, utilizing cross-sectional secondary data, included 5th and 7th grade students who attended SNAP-Ed-eligible public schools in California (n = 442,743 students; 4271 schools) and had complete 2016–17 state-mandated fitness test results. Latent class analysis was used to identify underlying school-based intervention combinations. Propensity score methods were used to ensure comparability of intervention and comparison schools, by calculating inverse probability weights. Multilevel models, using those inverse probability weights, assessed the associations between the identified intervention combinations and student cardiorespiratory fitness, as measured by VO2max. The models were adjusted for school-level variables (urbanicity, percent of students eligible for free- or reduced-price meals, total enrollment, and school type), child-level variables (age, gender, and race/ethnicity), and for clustering of students within schools. Results: We found that students attending schools with interventions focusing on comprehensive policy changes along with improving opportunities for physical activity had, on average, 1.17 mL/kg/min (95% CI: 0.72, 1.62) greater VO2max than students attending schools without any intervention. They also had statistically significantly greater VO2max compared to students attending schools with any other type of intervention combination. Conclusion: Our results suggest that comprehensive school-based physical activity interventions that include policy changes along with improving physical activity opportunities may be the most effective approach for improving fitness and may warrant prioritization in SNAP-Ed efforts.
