Colorado State University will implement the Food Friends and Mighty Moves program to address the need for Head Start and preschool programs to promote healthy food choices, dietary variety, and increased physical activity with children and parents from low-income and minority populations. The specific goals of the project are to: (a) decrease the risk of overweight and obesity among low-income preschool children and their parents by providing a direct service program that teaches the importance of nutrition and physical activity while reinforcing school readiness skills; (b) design, develop, and assess a physical activity intervention, Fun Moves, for preschool-aged children and their families as part of the Food Friends program; and (c) impact the knowledge, awareness, and practice of preschool teachers and providers by providing specialty trainings, nutrition education, and physical activity program materials, and information on nutrition and physical activity for preschool-aged children. The Mighty Moves project will reach up to 160 children and families from eight Head Start centers across Colorado. Children and families will be evaluated based on pre-intervention measures and post-intervention measures. The results are expected to support the Food Friends and Mighty Moves program as an effective approach to promoting healthy food choices, and improve child and family health.
