The USDA Food and Nutrition Service’s 1990 WIC Medicaid Study I found that prenatal WIC participation was associated with improved birth outcomes and savings in Medicaid costs. A 2003 study by Buescher, et al., found that WIC participation during childhood was associated with increased health care utilization and Medicaid costs, and concluded that WIC enhanced children’s linkages to the health care system.

In 2006, FNS asked the Institute of Medicine to review the WIC food packages. The IOM proposed major changes to improve nutrition and encourage breastfeeding but also expressed the concern that changes related to partial breastfeeding may have unintended consequences. The IOM recommended that FNS conduct an impact study evaluating the birth month breastfeeding changes to the WIC food packages.

This study is an analysis of very low birthweight among Medicaid newborns and the effect of prenatal WIC participation on the likelihood of very low birthweight.

The primary objective of this study was to determine the savings in Medicaid costs for newborns and their mothers during the first 60 days after birth resulting from participating the Special Supplemental Food Program for Women, Infants, and Children (WIC) during pregnancy.
