This is the first study to provide a comprehensive account of the WIC nutrition assessment and tailoring process. The nutrition and breastfeeding assessment process is critical to the delivery of individualized nutrition services and to meeting WIC’s mission. Study findings will inform FNS and WIC state and local agencies about how to enhance service delivery and improve retention of WIC participants.
The USDA Food and Nutrition Service conducts a variety of studies, evaluations, and related activities that respond to the needs of policymakers and managers and help ensure that nutrition assistance programs achieve their goals effectively. This plan provides short descriptions of projects that are expected to launch in fiscal year (FY) 2025.
It reflects decisions by FNS program and research staff and leadership on the best use of available research funding to meet current information needs that are aligned with agency priorities to improve program efficiency, integrity, and nutrition. FNS developed this plan in consultation with the agencies of the Research, Education, and Economics (REE) Mission Area.
Since 1988, FNS has produced biennial reports on WIC participant and program characteristics for program monitoring and managing WIC information needs. The 2022 report summarizes demographic, income, and health-related characteristics of participants with active certifications in April 2022.
This report provides improper payment estimates for fiscal year 2011 using a methodology for “aging” the 2005 bookend study. The methodology yields nationally representative estimates of the number of vendors that over- and undercharged and the amount of over- and undercharges across all WIC vendors.
This report provides improper payment estimates for FY 2010 using a methodology for “aging” the 2005 bookend study. The methodology yields nationally representative estimates of the number of vendors that over- and undercharged and the amount of over- and undercharges across all WIC vendors.
This report provides improper payments estimates for FY 2009 using a methodology for “aging” the 2005 bookend study. This updates previous reports providing estimates from 2005 to 2008.
About every 7 years, FNS performs a nationally representative study to examine the extent of error and abuse among food vendors authorized to accept WIC vouchers. The last bookend study was the 2005 WIC Vendor Management Study, which used fiscal year 2005 expenditure data to derive an estimate for 2004. Between bookend studies, there is a need to derive annual estimates of the level of improper payments for compliance with the Improper Payments Information Act of 2002. The purpose of the subsequent annual studies was to provide annual updates to the bookend studies using the developed aging methodology.
This report, the first of three, addresses the first objective of the study, which is to explore the characteristics and experiences of WIC participants.
In 2006, FNS asked the Institute of Medicine to review the WIC food packages. The IOM proposed major changes to improve nutrition and encourage breastfeeding but also expressed the concern that changes related to partial breastfeeding may have unintended consequences. The IOM recommended that FNS conduct an impact study evaluating the birth month breastfeeding changes to the WIC food packages.
This report begins with an overview of the WIC program, including its administrative structure and benefits, and a detailed description of the literature search protocol used to identify the studies included.
