WIC Infant and Toddler Feeding Practices Study-2 (WIC ITFPS-2) - Fourth Report

  • Consistent 4-year participation in WIC was associated with better diet quality.
  • The top reported reasons for continued WIC participation were the education received from WIC, the WIC food package, and the work of WIC personnel.

Read about these and other findings in WIC ITFPS-2, a longitudinal study from which multiple reports have been published. This most recent in the series looks at how children who started out on WIC are living, eating, and growing in the fourth year of life, and how WIC contributes to those outcomes. Other reports from this study include:


WIC Participant and Program Characteristics 2018

2020 Dietary Guidelines Advisory Committee's Scientific Report
This report’s evidence-based findings will inform USDA and the U.S. Department of Health and Human Services (HHS) as they co-develop the 2020-2025 Dietary Guidelines for Americans, which will provide recommendations on what to eat and drink to promote health and prevent chronic disease. The DGAs serve as the basis for the WIC food packages.

The WIC Food Cost Containment Practices Study examined about 30 voluntary food-specific restrictions and manufacturer rebates (on foods other than infant formula) with the goal of identifying practices that reduce food costs without adversely affecting participant outcomes.

 

On the Horizon

The WIC Nutrition Assessment and Tailoring Study (WIC NATS) is the first national study to provide a comprehensive account of the WIC nutrition assessment process as it unfolds at sites across the country. The study will:

  • Document how nutrition risk assessments are conducted;
  • Examine how the information gathered during the assessment is used to tailor Program benefits; and
  • Identify promising practices in the nutrition assessment process that are associated with participant and staff satisfaction, improved efficiency, and reduced staff burden
