Dissemination of healthy kids out of school principles for obesity prevention: A RE-AIM analysis.

Health-promoting behaviors for childhood obesity prevention are needed across multiple environments where children spend time, including out-of-school time (OST). Therefore Healthy Kids Out of School (HKOS) developed intervention strategies to promote three evidence-based principles (Drink Right, Move More, Snack Smart) for obesity prevention in OST. The strategies were developed with stakeholder input, disseminated, and evaluated (2012-2015) in two volunteer-led OST organizations, Boy Scouts of America (BSA) and 4-H, across three US states using the RE-AIM (Reach, Effectiveness, Adoption, Implementation, Maintenance) framework. Mixed methods were used involving surveys, key informant interviews, and organizational-level data collection. Sixty out of 81 (74.1%) BSA districts and 4-H counties reaching 84,590 children (72% of children participating in BSA and 4-H in three states) adopted the strategies. 530 surveys completed by local OST leaders at baseline and 294 at follow-up showed the percentage of programs offering healthy beverages and opportunities for physical activity increased from baseline to follow-up (beverages 26% baseline, 35% follow-up, odds ratio (OR) 1.53; physical activity 31% baseline, 45% follow-up, OR 1.79; all p < 0.05). The increasing trend for healthy snacks was statistically non-significant (p = 0.09). Leaders interviewed reported the strategies were easy to implement, a good fit with their program, facilitated success, and they expected to maintain the changes. Integration of HKOS customized materials (BSA patch and 4-H pin) on BSA and 4-H national websites is a broader indicator of maintenance. Intervention strategies developed with stakeholder input and disseminated with training can effectively facilitate healthy environments for children, and have potential for national scale.
