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 WIC program provides a combination of direct nutritional supplementation, nutrition education and counseling, and increased access to health care and social service providers for pregnant, breastfeeding, and postpartum women; infants; and children up to the age of five years. WIC seeks to improve fetal development and reduce the incidence of low birthweight, short gestation, and anemia through intervention during the prenatal period. Infants and children who are at nutritional or health risk receive food supplements, nutrition education, and access to health care services to maintain and improve their health and development.

WIC provides supplemental foods, nutrition education and access to health care to pregnant, breastfeeding and postpartum women, infants, and children up to age five. Since its inception in the early 1970’s, the program has received fairly widespread support and it has grown in size to serve 7.4 million participants in FY 1998 at an annual cost of around $4 billion.

The WIC and Head Start programs share common goals. Both programs strive to promote positive health and nutrition status for young families. Both programs provide young children and families with nutritious foods, health and nutrition education, and assistance in accessing on-going preventive health care. In many communities, WIC and Head Start serve the same families. By working together, programs have an opportunity to coordinate these services and maximize use of scarce resources (e.g., funding, staff, space). Working together can mean minimizing duplicative efforts on the part of families and staff; more opportunities for WIC and Head Start to benefit from each program’s strengths, expertise and best practices; and ultimately, more ways to make a positive impact on good health and nutrition for children and families.

This report reviews recent approaches to estimating the numbers of persons eligible for and participating in WIC. It also describes issues concerning these estimates that may be worthy of review and synthesizes research on these issues.

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.
