Impact of a longitudinal school-based intervention on soda intake among elementary and middle school children
Purpose: To evaluate the impact of the HEROES (Healthy, Energetic, Ready, Outstanding, Enthusiastic Schools) Initiative on soda intake among elementary and middle school students (N = 1827, 10 schools) who were exposed to the program for 18 months.
Significance: The HEROES Initiative is a multi-level longitudinal intervention with a rigorous evaluation framework that has been found to facilitate behavior change including soda intake among children.
Methods: The weight and height of students were measured, at baseline, 6 months, and 18 months. Sequential generalized estimating equations (GEE) of self-reported soda intake changes were modeled using SAS 9.3 while accounting for clustering effects within the same school.
Results: A significant downward trend (p < .001) was observed in soda intake for the models without school-level variables. When school-level variables were considered, a significant interaction (p = .023) was found between time and each school's fidelity score for program implementation. Soda intake decreased more rapidly for the students in schools with high fidelity scores than those in low fidelity scores.
Conclusion: Implementation of the HEROES Initiative with high fidelity appears to be effective in decreasing soda intake among elementary and middle school children while heterogeneity of soda intake changes is related to well-established individual behavioral covariates.
