Phase II was a methodological study, conducted in six sites during 2015–2016, to test an approach to determine its feasibility for a national evaluation.

The USDA Food and Nutrition Service’s 1990 WIC Medicaid Study I found that prenatal WIC participation was associated with improved birth outcomes and savings in Medicaid costs. A 2003 study by Buescher, et al., found that WIC participation during childhood was associated with increased health care utilization and Medicaid costs, and concluded that WIC enhanced children’s linkages to the health care system.

WIC Participant and Program Characteristics 2016 (PC 2016) summarizes the demographic characteristics of participants in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) nationwide in April 2016. It includes information on participant income and nutrition risk characteristics, estimates breastfeeding initiation rates for WIC infants, and describes WIC members of migrant farm-worker families. PC 2016 is the most recent in a series of reports generated from WIC state management information system data biennially since 1992.

The WIC Infant and Toddler Feeding Practices Study 2 (WIC ITFPS-2)/ “Feeding My Baby” Study captures data on caregivers and their children over the first 5 years of the child’s life after WIC enrollment to address a series of research questions regarding feeding practices, associations between WIC services and those practices, and the health and nutrition outcomes of children receiving WIC.

This report, the latest in a series of annual reports on WIC eligibility, presents 2015 national and state estimates of the number of people eligible for WIC benefits and the percents of the eligible population and the US population covered by the program, including estimates by participant category.

The phase I interim report, is the second of three reports. The first report, the Evaluation of White Potatoes in the Cash Value Voucher: Letter Report, recommended allowing white potatoes for purchase with the cash value voucher. This second report presents the evidence, analyses, and framework that will be applied to develop the final report (phase II), which will include recommendations for potential modifications to the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) food packages.

The WIC Nutrition Education Study (NEST) provides detailed information on WIC nutrition education services and includes the following two phases:

-- Phase I: Comprehensive nationally representative description of WIC nutrition education processes and features.

-- Phase II: Pilot study of the impact of WIC nutrition education on nutrition and other behaviors in six WIC sites.

This report presents the Phase I results of the study.

This report is a supplement to the WIC Participant and Program Characteristics 2014 biennial report. It describes the content of Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) food packages for packages or prescriptions issued to WIC participants in April 2014.

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.
