The federal Supplemental Nutrition Assistance Program for Women, Infants and Children (WIC) provides nutritious foods, information on healthy eating including breastfeeding promotion and support, and referrals to health care to over 6.3 million low-income pregnant, postpartum, and breastfeeding women, infants, and children up to age 5 in the US. Nutrition Policy Institute's (NPI) Lorrene Ritchie is the Co-Principal Investigator of the national WIC Infant and Toddler Feeding Practices Study-2 (ITFPS-2), which received additional funding from the United States Department of Agriculture (USDA) in partnership with Westat, Inc. to extend data collection for children up to 9 years of age enrolled in the national WIC Infant and Toddler Feeding Practices Study-2 (ITFPS-2). Ritchie and her NPI research team will contribute to the investigation of dietary practices and the health and nutritional status of children in this cohort during their ninth year of life. This project builds off the WIC ITFPS-2 study funded by the USDA Food and Nutrition Services, which began in 2011. The study extension begins in October 2020 and continues for five years.
