Title: Obesity Prevention in Head Start: Míranos! Program
Brief Summary: The prevalence of obesity remains high in American children aged 2-5 while one in three Head Start children is overweight or obese. The proposed study is designed to test the efficacy of an early childhood obesity prevention program which promotes healthy growth in predominantly Latino children in Head Start.

The program is a group clustered randomized controlled trial in partnership with two local Head Start organizations to address key enablers and barriers in obesity prevention in young children. The study has three specific aims:

1. To test the efficacy of the Miranos! intervention on healthy weight growth (primary outcome) in normal weight, overweight, and obese children.
2. To test the impact of the Miranos! intervention on children's physical activity, sedentary behavior, sleep, and dietary behaviors (secondary outcomes).
3. To evaluate cost-effectiveness of the Miranos! intervention.

Miranos! will be delivered in Fall and Spring (8 months) and followed by a summer health campaign.
