The Healthy Children, Healthy Families: Parents Making a Difference! (HCHF) curriculum is a Cornell curriculum for parents and caregivers focusing on the behaviors most likely to help children avoid unhealthy weight gain. These behaviors include drinking water or milk instead of sweetened beverages, eating more vegetables and fruits, playing actively, eating fewer high-fat and high-sugar foods, limiting screen time, and having sensible serving sizes. The 8-session curriculum uses a learner-centered dialogue approach, hands-on activities and role plays. The study will include 300 participants with young children 3-5 years old in Head Start and childcare programs in New York City using a randomized control design. In period 1 (9 weeks), half the groups will receive HCHF education (immediate education, IE) and half will serve as controls, receiving no education (delayed education, DE). In period 2 (9 weeks), DE will receive education; IE will receive no education and be followed longitudinally for periods 2 and 3. In period 3 (16 weeks), neither group will receive education and both will be followed longitudinally. Data will be collected at each time point using validated measures, including the HCHF Checklist developed by the investigators and complementary measures that assess parenting feeding practices, food behavior in parents, food behavior in children, and parent self-efficacy around obesity prevention behaviors. It is hypothesized that change pre- to post- HCHF will be greater than control groups, and changes in behavior will be retained post-education.
