More than half of all children in the United States aged 3 to 6 years are enrolled in child care centers. Maine received funds from the U.S. Department of Health and Human Services’ Communities Putting Prevention to Work to promote the adoption of Nutrition and Physical Activity Self-Assessment for Child Care (NAPSACC), an evidence-based program for the child care setting. We evaluated the rollout and adoption of NAP SACC in Maine using multiple methods. Our findings suggest that the NAP SACC program has been successfully adopted in Maine. Nutrition and physical activity policies and offerings have improved, especially with regard to purchasing healthier options in the child care setting.
