Project: WIC Food Package Revisions: Impact on Food Purchases and Access to Healthy Foods
Award Year: 2010
Amount of award, fiscal 2010: $265,000.00
Institution: Yale University
Principal Investigator: Tatiana Andreyeva
Status: Ongoing
Detailed Objective: In 2009, major revisions to the food packages in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) were implemented with the objective of increasing the provision of healthy foods to low-income women, infants, and children. This project will assess the impact of this policy change on access to healthy foods and purchasing behavior of major WIC food categories (fruits and vegetables, whole grains, and lower fat milk) among WIC participants. Using scanner data from a major supermarket chain operating in New England, the study will compare WIC participant purchases before and after the revisions. To show trends in food market factors and on access to healthy foods, the study will conduct store inventories in a representative sample of food retailers 18-20 months after implementation of the revisions, and compare the results to similar assessments conducted prior to implementation of the WIC food package revisions and 1 year after the revisions. The study will also identify store and community characteristics that modify the impact of the WIC food package revisions on access to healthy foods.
