This publication is based on the WIC Infant Feeding Practices Study (WIC-IFPS) sponsored by FNS. The WIC-IFPS is a one-year longitudinal study, which describes the infant feeding practices over the first year of life among a nationally representative sample of approximately 900 mothers who participated in WIC while they were pregnant.

FNS asked Mathematica Policy Research, Inc., (MPR) to assess the CPS estimates in relation to alternative estimates from the Survey of Income and Program Participation (SIPP), which collects longitudinal monthly income data.

To manage the Child Nutrition programs effectively, FNS collects and analyzes information from annual State-level management reports. However, because these State-level reports vary considerably in both format and content, FNS is unable to rely on this source for all of its ongoing information needs.

The study collected data on-site on food, labor, and other meal production costs for a five day period. A major goal was to test the feasibility of identifying meal production costs that were not charged to the SFA account (to obtain full costs) and directly allocating costs to different SFA activities.

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.
