The WIC Participant and Program Characteristics (PC 2004) report summarizes demographic characteristics of WIC participants nationwide in April 2004, along with information on participant income and nutrition risk characteristics. A national estimate of breastfeeding initiation for WIC infants is included. The report also describes WIC members of migrant farm-worker families.

WIC seeks to improve fetal development and reduce the incidence of low birthweight, short gestation, and anemia through intervention during the prenatal period. This publication is the seventh report in the series of studies on WIC participants and program characteristics.

The 1996 study of WIC program and participant characteristics, like PC92 and PC94, is substantially different from earlier efforts to collect data on WIC participants. PC96 employs the prototype reporting system which was developed by FNS for the collection of participant information from state WIC agencies.

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.

The study examined the costs charged to SFAs (reported costs), as well as those costs incurred by the school district in support of SFA operations, but not charged to the SFA (unreported costs). Together, the reported costs and the unreported costs are the full cost of meal production.

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.

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.
