The federal Special Supplemental Nutrition program for Women, Infants and Children, known as WIC, aims to safeguard the health of over 6 million low-income women, infants, and children up to age 5 in the United States by providing nutritious foods, information on healthy eating, and referrals for additional services. Nutrition education is an essential feature of WIC, making it unique compared to other federal nutrition programs. Researchers evaluated differences in WIC participants' perceptions and satisfaction with WIC nutrition education and services by race, ethnicity, and language preference in a sample of nearly 3000 California WIC participants surveyed in 2019. Spanish-speaking Hispanic participants reported the highest levels of satisfaction with WIC nutrition education compared to other groups. Hispanic participants were also more likely to change their behaviors after receiving WIC nutrition education compared to non-Hispanic White and Black participants. Participants prefer to receive WIC nutrition education through a variety of methods including in-person one-on-one, video/DVD, online, group sessions, and two-way text messaging. Across all groups, participants reported that the fruits and vegetables they receive in the child WIC food package was the top reason for continuing to participate in WIC. These findings can inform efforts to improve WIC participant retention. The study was published in the journal Nutrients.
