Allison Karpyn, associate professor in CEHD’s  Department of Human Development and Family Sciences, offers new insight into how state regulations affect families’ access to healthy food.

In “USDA Special Supplemental Nutrition Program for Women, Infants and Children (WIC) Vendor Criteria: An Examination of U.S. Administrative Agency Variations,” Karpyn and her co-authors  Matthew J. Landry, Kim Phan, Jared T. McGuirt, Alek Ostrander, Lilian Ademu, Mia Seibold, Kathleen McCallops, Tara Tracy and Sheila E. Fleischhacker examine the criteria for WIC vendors across 89 U.S. states and tribal territories and find that some of these regulations may restrict access to food, rather than facilitate it.
