In 2007, the NYC Department of Health and Mental Hygiene added physical activity and nutrition policies for group daycare centers to the NYC Health Code. This project will evaluate whether NYC group daycares meet the new policies, and assess perceived difficulties, barriers, and predictors of implementation associated with these policies. Survey data will be collected from directors and teachers about adherence to the new policies and perceived difficulties and barriers, and data will be recorded on foods and beverages consumed and activities performed by preschool-age children from when the daycares open through lunchtime.
