Title: Effectiveness of Differing Levels of Support for Family Mealtimes on Obesity Prevention Among Head Start Preschoolers
Brief Summary: Socioeconomic disparities in early childhood place low-income children at 1.5 to 2 times higher risk for obesity compared to middle- to upper-income children. Obesity interventions have turned toward the promotion of family mealtimes. This study will test the effects of 6 intervention components reflecting differing levels of supports to ultimately reduce childhood obesity prevalence and increase the frequency of healthy family mealtimes and improve dietary quality. The investigators will test 6 intervention components in Phase 1 (Screening Phase), resulting in the implementation and evaluation via a randomized controlled trial of a "final" intervention model in Phase 2 (Confirming Phase). The investigators hypothesize that providing low-income families with effective supports to enhance family capability to plan and implement family mealtimes will lead to improvements in children's adiposity indices, dietary quality and frequency of family meals.
