Data & Research
The WIC Participant and Program Characteristics (PC 2006) report summarizes demographic characteristics of WIC participants nationwide in April 2006, 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.
To assist nutrition educators in their use of relevant research, FNS conducted a review of studies on: Message framing, Use of interactive technology to tailor messages, and Intervention intensity. The review was intended to document how these specific features of nutrition messages and interventions influence the likelihood of promoting more healthful food choices.
In 1991 and 1998, FNS conducted national studies of WIC vendors to determine the extent of vendor violation of program rules. After the 1998 study, FNS issued regulations to correct vendor practices. The 2005 study replicates the 1998 study to determine whether the regulations were effective, and to measure the frequency of vendor violations and the degree to which vendors charge accurate prices for WIC transactions.
The WIC Nutrition Education Assessment Study was conducted by Abt Associates Inc. of Cambridge, Massachusetts, under contract with the Food and Nutrition Service (FNS) of the United States Department of Agriculture (USDA). The study was designed by FNS to fill several important gaps in information about the nutrition education component of the WIC Program.
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.
