Since 1992, FNS has produced biennial reports on WIC participant and program characteristics based on the WIC Minimum Data Set compiled from state management information systems. The 20 items included in the MDS are collected as part of ongoing WIC operations and consist primarily of in formation related to participant eligibility.

This is a report of the National Academies' Institute of Medicine (Food and Nutrition Board), published here by permission.

This study examines the trends in the prevalence of overweight among WIC children during the 1990s. The study is based on data collected by the biennial WIC Participant and Program Characteristics Studies (1992, 1994, 1996 and 1998). 

The purpose of the study was to learn the extent to which retail grocers, defined as "vendors" in the WIC Program, authorized to provide food to WIC participants, were violating program rules and procedures, and to determine which programmatic and/or demographic variables could be associated with vendor violations.

In 1994, FNS initiated the WIC Nutrition Education Demonstration Study. The demonstration had two components: a comparison of the effects of innovative and traditional WIC nutrition education for prenatal participants; and a study of the feasibility and effectiveness of providing nutrition education to preschool (three-and-four-year-old) WIC participants. The report summarized here describes the design and implementation of the child nutrition education demonstration and presents findings describing the effectiveness of the demonstration.

The study evaluated the effectiveness of three innovative approaches to nutrition education in the Special Supplemental Nutrition Program for Women, Infants, and Children. Two of these education innovations were designed for educating prenatal women; the third focused on nutrition education for 3- and 4-year-old WIC participants. This executive summary and report describe the evaluation and results of the educational interventions for prenatal women.

The Conference on Access to Food, held in Washington, D.C., on Sept. 18 and 19, 1995, was sponsored by the U.S. Department of Agriculture Food and Consumer Service. The conference was held to bring together food access experts to share their knowledge and help USDA build an agenda to increase access to food for low-income Americans.

WIC Dynamics is a study of the impact of participation growth associated with infant formula rebates, new regulatory and legislative requirements, economic factors occurred since 1988.
