Food-Package Assignments and Breastfeeding Initiation Before and After a Change in the Special Supplemental Nutrition Program for Women, Infants, and Children

By Wilde P, Wolf A, Fernandes M, Collins A

Background: In 2009, the USDA implemented an interim rule that changed the prescribed foods in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). Options for mother and infant dyads include a full breastfeeding package with no infant formula, a partial breastfeeding package with some infant formula, and a full formula package with a smaller postpartum food package for the mother. The changes were designed to encourage WIC mothers to choose breastfeeding for their infants.

Objective: The purpose of this study was to measure changes in the following 3 outcomes: WIC food-package assignments, WIC infant formula amounts, and breastfeeding initiation.

Design: We compared outcomes before and after implementation of the interim rule in a national random sample of 17 local WIC agencies (LWAs). The data source was administrative records for 206,092 dyads with an infant aged 0–5 mo in the sampled LWAs.

Results: There were changes in WIC food-package assignments and infant formula amounts but no change in breastfeeding initiation. For dyads in whom the infant was in his or her birth month, the percentage of mothers who received the partial breastfeeding package fell from 24.7% (preimplementation) to 13.8% (postimplementation), the percentage of mothers who received the full breastfeeding package rose from 9.8% (preimplementation) to 17.1% (postimplementation), and the percentage of mothers who received the full formula package rose from 20.5% (preimplementation) to 28.5% (postimplementation).

Conclusions: After the change, fewer WIC mothers of new infants received the partial breastfeeding package. More WIC mothers received the full breastfeeding package, but more mothers also received the full formula package.
