The Healthy Opportunities for Physical Activity and Nutrition (HOP’N) Home project is a novel approach to engage parents through early childhood education programs, specifically, FCCH to prevent childhood obesity. We conducted a feasibility study using the RE-AIM framework (Glasgow et al., 1999). The RE-AIM framework provides a series of metrics to assist researchers with the development and evaluation of interventions that include Reach, Effectiveness, Adoption, Implementation, and Maintenance. Our goal was to reach (R) a large proportion of young children to effect (E) prevention of overweight/ obesity. Success required staff and parent adoption (A), implementation (I), and maintenance (M) of HOP'N practices. We hypothesized that: 1) early child care providers and parents would adopt and implement HOP'N practices; 2) children's asking for, and parent's provision of healthy opportunities would increase after intervention; and 3) prevalence of children's overweight and obesity would decrease after intervention.
