Description:Purpose:
To explore whether school poverty level and funding modified the effectiveness of an evidence-based Comprehensive School Physical Activity Program called Health Empowers You! implemented in elementary schools in Georgia.
Design:
Secondary data analysis of a multi-level, cluster-randomized controlled trial.
Setting:
40 elementary schools in Georgia in 2018–2019.
Subjects:
4th grade students in Georgia.
Measures:
Intervention schools implemented the Health Empowers You! program to increase school-day physical activity. The outcome was average daily moderate-to-vigorous physical activity, school free-reduced price lunch (FRPL) percentage and per pupil expenditures were effect modifiers.
Analysis:
Separate linear mixed regression models estimated the effect of the intervention on average daily moderate-to-vigorous physical activity, with interaction terms between intervention status and (1) school FRPL percentage or (2) per pupil expenditures.
Results:
The effect of the intervention was significantly higher in schools with higher FRPL percentage (intervention*school % FRPL β (95% CI): .06 (.01, .12)), and was modestly, but not statistically significantly, higher in schools with lower per pupil expenditures.
Conclusion:
Findings support the use of the Health Empowers You! intervention, which was effective in lower income schools, and may potentially reduce disparities in students’ physical activity levels.
