The aim of this study is to describe eating environments and policies in Head Start at the national level, examining their variation by program characteristics. In partnership with DHHS and USDA, this project will develop a survey to describe eating environments and policies in Head Start (including issues such as foods offered, use of nutrient-based standards, community and parent outreach, food service financing, staff training and technical assistance, barriers and facilitators to change), and administer this survey to all program directors nationwide. These data may inform decisions about program changes that might be feasible and effective for preventing obesity.
