WIC Participation


Nutrition and Health Characteristics of Low-Income Populations: Volume II, WIC Participants and Nonparticipants

This research was designed to establish a baseline from which to monitor the nutritional and health characteristics of WIC participants and non-WIC participants over time. Because of age-based variations in the survey protocols and small samples of pregnant and postpartum women, data were not consistently available among women, infants, and children. The richest datasets were available for children, and datasets were most limited for pregnant women.


Nutrient Intakes and Food Choices of Infants and Toddlers Participating in WIC

Using data from the 2002 Feeding Infants and Toddlers Study (FITS), the researchers examines the nutrient intakes, foods consumed, and feeding patterns of infants and toddlers participating in WIC. Results found that infants enrolled in WIC were less likely to have been breastfed, compared with other US children. Significant numbers of WIC and non-WIC toddlers did not consume enough fruits and vegetables.


An Innovative Blood Lead Screening Program for Indian Children

The authors' goal was to screen Indian children on the reservation who were participating in WIC and Head Start. researchers screened close to 100% of the young children on the Rocky Boy reservation. The average blood lead level for these Indian children, ages 1 to 5, was 2.4 micrograms/dL, which is not significantly different from that of children of the same age nationally.


The Impact of the Special Supplemental Nutrition Program for Women, Infants, and Children on Child Health

The authors used data from the third National Health and Nutrition Examination Survey (NHANES) to analyze the effect of the WIC Program and other factors on the health of US preschool children. Findings revealed that the WIC Program had a significant positive impact on the overall health of children. In particular, children in households participating in WIC were significantly more likely to be in excellent health.


Child Participation in WIC: Medicaid Costs and Use of Healthcare Services

This study examines the relationship between child participation in WIC to Medicaid costs and use of healthcare services in North Carolina. Medicaid-enrolled children participating in the WIC Program showed greater use of all types of healthcare services, compared with Medicaid-enrolled children who were not WIC participants.


The WIC Program: Background, Trends, and Issues

This report described the WIC Program: how it works, its history, program trends, and the characteristics of the population it serves. It also examines issues related to program outcomes and administration. How the WIC community responded to these issues might have a large impact on future program operations.


A Longitudinal Study of WIC Participation on Household Food Insecurity

The researchers studied the association between women's and children's duration of WIC participation and household food security status. Their results showed that among those with initial household food insecurity with hunger, an additional WIC visit reduced the odds of any household food insecurity and of household food insecurity with hunger at the last visit. Earlier and longer WIC participation might improve household food security status, particularly of vulnerable groups.
