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.
 

The WIC Participant and Program Characteristics (PC 2004) report summarizes demographic characteristics of WIC participants nationwide in April 2004, along with information on participant income and nutrition risk characteristics. A national estimate of breastfeeding initiation for WIC infants is included. The report also describes WIC members of migrant farm-worker families.

FNS published “The WIC Vendor Management Study, 1998” in July 2001 which examined, in part, the extent to which retail grocers, defined as WIC “vendors” were violating program rules and regulations. The 1998 study is a follow-up to the “WIC Vendor Issues Study, 1991” published by FNS in May 1993. 

The Association of State and Territorial Public Health Nutrition Directors, with support from a cooperative agreement with USDA, conducted a census of the professional and paraprofessional public health nutrition workforce in the states and territories. ASTPHND has conducted periodic profiles of the public health nutrition workforce since 1985. Members of ASTPHND in their respective states and territories conducted the census reported in this paper during 1999-2000. Prior to this, ASTPHND's last survey was conducted in 1994.
