The Special Supplemental Nutrition Program for Women, Infants and Children—commonly known as WIC—is celebrating 50 years of improving the health of participants, including those who are pregnant, new parents, infants, and children under five. The American Rescue Plan Act of 2021 provided the US Department of Agriculture with $390 million, available through FY 2024, to carry out outreach, innovation, and program modernization efforts to increase participation and redemption of benefits for both the WIC program and the WIC Farmers' Market Nutrition Program. The USDA contracted with Mathematica and their partners, including the Nutrition Policy Institute, to design and implement an evaluation of these projects being implemented across 89 WIC State agencies and 51 Farmers Market Nutrition Program State agencies. The evaluation will assess whether the modernization projects being implemented are associated with increases in enrollment, participation, retention, and redemption of benefits; improvements in participant experience; and reduced disparities in program delivery. The five-year project began in September 2023. NPI research project team members will include Lorrene Ritchie, Danielle Lee, Celeste Felix, KC Whitsett and Reka Vasicsek.

Over 38,000 participants in the federal Special Supplemental Nutrition Program for Women, Infants and Children, commonly known as WIC, completed a satisfaction survey in summer of 2023. Conducted across 21 participating WIC state agencies in all US Department of Agriculture administrative regions, the survey showed high satisfaction with the WIC program and that participants feel respected, valued and included by WIC staff. The hybrid WIC services introduced during  the pandemic were successful, with two-in-three using in-person services, over half using remote services and nearly all finding it is easy to schedule appointments. The top reasons for WIC participation were the fruits and vegetables in the WIC food package followed by other foods and the education and support from WIC staff. Participants expressed interest in using WIC benefits at farmers markets and requested expanded fruit and vegetable options in states that don't authorize canned or frozen options. The survey illuminated challenges participants experience when shopping for WIC foods, reasons for not buying all their WIC foods, and their desire for expanded shopping options. Results align with the recently finalized WIC food package changes. Findings are available in the report “2023 WIC Multi-State Participant Satisfaction Survey” published online on April 9, 2024. The survey was also cited in an article in The New York Times, "Food Aid Program for Mothers and Children Will Provide More Fruits and Vegetables" and another article in NBC News, "Low-income families have more to spend on fruit and veggies thanks to new WIC rule," both published on April 9, 2024. The project was conducted by Lorrene Ritchie, Danielle Lee, Celeste Felix, Ken Hecht and Hannah Thompson from the Nutrition Policy Institute, Loan Kim, Theresa Tran, Claire Burton and Amanda Kiang from Pepperdine University and Georgia Machell from the National WIC Association. The project was funded by the National WIC Association through a grant from the Robert Wood Johnson Foundation.

Milk provides various nutrients such as calcium, protein, and vitamin D, which are essential for health and brain development. In the US, it is advised that children switch from the recommended whole cow's milk from ages 1-2 to low-fat or non-fat milk after age 2 to reduce saturated fat and calorie intake, however, few studies support this recommendation. Nutrition Policy Institute researchers and Anisha Patel with the Stanford Medicine Department of Pediatrics recently received funding for a research study from the National Institute of Health. The study, Milk Type in Toddlers or Milk-TOT, includes a randomized controlled trial that will investigate how whole and low-fat 1% milk affect child adiposity, dietary intake, and health outcomes, aiming to provide evidence-based recommendations for dietary guidelines. The California Dairy Research Foundation provided additional funding to include the assessment of the impacts of varying milk types on participating children's gut microbiota diversity, in collaboration with Justin Sonnenburg with the Stanford Medicine Department of Microbiology and Immunology. Parents or caregivers with children between 23-30 months old living in the San Francisco Bay Area may be eligible to participate in the study. The four-year project began in January 2024 and is estimated to end in June 2028. The project is led by Lorrene Ritchie as the principal investigator, and NPI researchers, Kassandra Bacon, Ryan Williams, Suzanne Rauzon, Celeste Felix, Hannah Thompson, Fanta Jimissa, Reka Vasicsek and Meirong Liao.

Nutrition Policy Institute researchers will present at the American Public Health Association 2023 Annual Meeting & Expo . The conference brings in over 1,000 sessions, centered on creating a healthier nation by working together to overcome social and ethical challenges. NPI researchers Wendi Gosliner, Lorrene Ritchie, Christina Hecht, Kenneth Hecht and Monica Zuercher co-author two poster sessions.  The first is presented by Leah Chapman from Merrimack College titled, “Universal free school meals during the pandemic: A qualitative analysis of parent opinions from California and Maine” on November 13 from 2:30 p.m. to 3:30 p.m. The second is presented by Deborah Olarte from Merrimack College on November 13 from 2:30 p.m. to 3:30 p.m. titled, “School food authorities' perceptions of the barriers to student participation in universal school meals during the 2021-2022 school year: A mixed-methods study.” The conference will take place in Atlanta, Georgia from November 12-15 with live virtual options for attendees.
