A new research brief developed by the Nutrition Policy Institute highlights promising school-based CalFresh Healthy Living—California's SNAP-Ed program—physical activity interventions. The study used latent class analysis to describe the predominant combinations of CFHL physical activity interventions implemented in California public schools in partnership with local health departments. Using Fitnessgram data from over 440,000 students in nearly 4,300 schools, the researchers assessed whether intervention combinations were associated with student cardiorespiratory fitness, as measured by V02 max. The study found that students in schools with CFHL interventions focused on establishing or improving wellness policies and increasing opportunities for physical activity had better cardiorespiratory fitness than students in schools without CFHL interventions or in schools with other types of CFHL intervention combinations. The peer-reviewed study was authored by Sridharshi Hewawitharana, Gail Woodward-Lopez, and Wendi Gosliner from the Nutrition Policy Institute, Punam Ohri-Vachaspati and Francesco Acciai from Arizona State University, and John Pugliese from the California Department of Public Health. The research brief was created by NPI's CalFresh Healthy Living Evaluation Unit, including: Summer Cortez, Reka Vasicsek, Miranda Westfall, and Sridharshi Hewawitharana.
Increasing participation in school meal programs can improve dietary quality and reduce nutrition insecurity. School food service directors have indicated an urgent need for marketing materials encouraging school meal participation. Nutrition Policy Institute will partner with Anna Grummon of Stanford University to develop and evaluate a marketing campaign to increase school meal participation. The evaluation will help to determine the school meal messaging that most resonates with parents. The two-year project, “Developing and evaluating a marketing campaign to increase school-meal participation to improve children's dietary quality and reduce food insecurity,” was funded by the Robert Wood Johnson Foundation's Healthy Eating Research program. The project started in November 2023 and includes NPI's Christina Hecht, Ken Hecht and Reka Vasicsek.
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.

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.
A new research brief developed by the Nutrition Policy Institute outlines the results and implications of the 2023 study: “Supplemental Nutrition Assistance Program Education reductions during COVID-19 may have exacerbated health inequities.” The study examined changes in Supplemental Nutrition Assistance Program Education programming by California's local health departments during the COVID-19 pandemic. In March 2020, when schools and other institutions closed their doors in response to the COVID-19 emergency, the impact on public health programs like SNAP-Ed was immediate and large. As the pandemic continued, California's local health departments reported numerous challenges, including the diversion of staff, funding and other resources from programs like SNAP-Ed to emergency response. NPI researchers documented dramatic reductions in the reach and dose of local health department SNAP-Ed programming during the early stages of the pandemic. Reductions disproportionately impacted disadvantaged communities, including those with higher poverty, higher proportions of Black and Latino residents and less healthy neighborhood conditions. Disproportionately reduced access to important health programs may have worsened health disparities in diet and physical activity-related chronic diseases, as well as increasing susceptibility to COVID-19. This study demonstrates the importance of an equity-centered approach to promoting healthy eating and active living, even—or perhaps especially—during public health emergencies. The peer-reviewed study was authored by NPI researchers Gail Woodward-Lopez, Erin Esaryk, Sridharshi Hewawitharana, Janice Kao, Evan Talmage and Carolyn Rider. The research brief was created by NPI's CalFresh Healthy Living Evaluation Unit, including: Carolyn Rider, Miranda Westfall, Reka Vasicsek and Summer Cortez.
