Data & Research
This study used 2011–2016 National Health and Nutrition Examination Survey (NHANES) data to examine the relationship between estimated program participation, diet quality, indicators of nutrition and health, food consumption patterns, and nutrient intakes.
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.
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.
The WIC Infant and Toddler Feeding Practices Study 2/“Feeding My Baby” Study captures data on WIC caregivers and their children over the first 5 years of each child’s life to address a series of research questions regarding feeding practices, the effect of WIC services on those practices, and the health and nutrition outcomes of children on WIC.
The National Academies of Sciences, Engineering, and Medicine convened an expert committee to review and assess the nutritional status and food and nutritional needs of the WIC-eligible population and provide recommendations based on its review and grounded in the most recently available science. The committee produced three reports as part of this task.
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 uses data from the National Health and Nutrition Examination Survey to provide a comprehensive picture of the nutrient intakes, food choices, and diet quality of young children who are WIC participants, income-eligible nonparticipants, and higher income participants.
This report includes findings from formative research undertaken to help USDA assist child care providers in following the nutrition, physical activity, and electronic media use recommendations outlined in the Healthy, Hunger-Free Kids Act of 2010.
This report estimates the average monthly food costs for each of 5 WIC participant subgroups and estimates total dollars spent on 17 major categories of WIC-eligible foods in FY 2010. The participant and food level costs in this report are USDA’s first estimates since implementation of the 2009 WIC food package changes.
