A 2025 study in the Current Developments in Nutrition, revealed that participation in the Special Supplemental Nutrition Program for Women, Infants, and Children, commonly known as WIC, may modestly decrease the risk for low gestational weight gain and slow gestational weight gain rate. Notably, WIC participation was not associated with lower risk of high gestational weight gain or accelerated gestational weight gain rate. Gestational weight gain can be a significant clinical indicator of maternal health and healthy fetal development. WIC provides resources for low-income pregnant women and families of young children including a monthly food package, nutrition counseling, breastfeeding support, and referrals to health and social services. This study provided important insight on WIC participants during pregnancy that may inform potential strategies to improve aspects of the program including nutrition counseling and the WIC food package. A recent 2024 change saw the addition of fish and nuts to the WIC package, which can be healthy foods to support pregnancy. This research was conducted by Caitlin French from the Nutrition Policy Institute and NPI-affiliated researcher Susana Matias from the University of California, Berkeley. This study was supported by the RIDGE Partnership, with funding from the USDA Economic Research Service and Food and Nutrition Service.
