Feasibility and effectiveness of two built environmental interventions on physical activity among 3-5-year-old preschoolers.

Nurses work to maintain and improve health at multiple levels of influence and are in strategic positions to educate and support PA to maintain and improve the health of all ages. School-based PA interventions have been reported with varying success. The feasibility of this study provides insight into the challenges in planning and conducting school-based interventions including enrollment, attrition, and accelerometer wear-time compliance. Despite our interventions, there was no positive response to either intervention, with PA declining at each time period in both groups. However, baseline PA was significantly higher than in previous studies. Schools can provide children with opportunities to accumulate PA.
