This project is designed to identify and evaluate environmental and policy features related to healthy eating among elementary schools located throughout low-income, Hispanic and non-Hispanic, urban and rural Colorado. In a longitudinal design, student diet recalls and school level food-related sales records will be used to assess diet and eating patterns over time. Environmental and policy profiles of schools and their immediate surroundings will be used to identify key features that predict healthy eating and key informant interviews will be conducted to understand factors influencing adoption, implementation and sustainability of environmental and policy changes.
