A recent study finds that comprehensive school-based Supplemental Nutrition Assistance Program-Education, also known as SNAP-Ed, interventions focused on improving wellness policies and increasing physical activity opportunities are associated with better student fitness. Researchers identified predominant combinations of school-based, physical activity-focused SNAP-Ed interventions and then looked at how they affected student fitness. Study data included over 442,000 fifth and seventh-grade students attending nearly 4,300 public schools in California communities with low-income in 2016-2017. Students in schools with SNAP-Ed interventions combining policy changes and improved physical activity opportunities had better cardiorespiratory fitness, as measured by VO2 max. On average, these students had 1.17 mL/kg/min greater VO2max than students at schools without interventions. They also had greater VO2 max compared to students in schools with any other type of intervention combination. This study suggests that focusing on both wellness policy changes and increased physical activity opportunities may have a synergistic effect and may warrant prioritization in SNAP-Ed program planning and implementation. The study, published in Preventive Medicine, was conducted by Nutrition Policy Institute researchers Sridharshi Hewawitharana, Gail Woodward-Lopez, Hannah Thompson, and Wendi Gosliner; Arizona State University researchers Punam Ohri-Vachaspati and Francesco Acciai; and California Department of Public Health researcher John Pugliese.
A new research brief developed by the Nutrition Policy Institute outlines the results and implications of the 2020-21 study, “The impact of SNAP-Ed interventions on California students' diet and physical activity during COVID-19.” For many school-aged children in the United States, school closures prompted by the COVID-19 pandemic resulted in the loss of consistent and reliable access to nutritious meals and opportunities for physical activity. Local health departments implementing the CalFresh Healthy Living program adapted their program delivery to continue to reach children with interventions that promote healthy eating and active living. In their study, NPI evaluators found that CalFresh Healthy Living interventions had a positive impact on students' fruit and vegetable intake. The study and research brief were authored by NPI's CalFresh Healthy Living Evaluation Unit, including Amanda Linares, Kaela Plank, Sridharshi Hewawitharana, Gail Woodward-Lopez, Miranda Westfall, Reka Vasicsek and Summer Cortez.
Findings from a recent study indicate that most California schools are providing drinking water that meets current safety standards. However, the authors suggest that continued attention and investments are needed to assure tap water safety in all schools. Researchers partnered with 83 schools from a representative sample of 240 California public schools to collect and analyze tap water samples for five common drinking water contaminants: arsenic, nitrate, hexavalent chromium, copper and lead. The first three may occur naturally in groundwater but can also come from agricultural or industrial activities. Lead and copper are heavy metals that may be found in building plumbing and can be present in tap water under certain conditions. No tap water samples violated the California state action level for arsenic or nitrate, two contaminants that should be brought to levels at or below state standards by water utility treatment of their sourcewater. Four percent of schools had at least one sample that exceeded California's proposed 10 parts per billion action level for hexavalent chromium. Four percent of schools exceeded the 1300 ppb state action level for copper. A notable feature of the study was its detailed analysis of lead in tap water. Four percent of study schools had at least one first-draw tap water sample that exceeded the 15 ppb state action level for lead, 18% exceeded the US Food and Drug Administration's bottled water standard of 5 ppb, and 75% exceeded the American Academy of Pediatrics recommendation of 1 ppb. Researchers found that turning on the affected taps to “flush” pipes for 45 seconds reduced observed lead concentrations above 15, 5, and 1 ppb to 2%, 10%, and 33% of schools, respectively. These findings provide valuable information for mitigating the presence of lead in tap water. The study, “A Comprehensive Examination of the Contaminants in Drinking Water in Public Schools in California, 2017-2022”, was published online on September 4, 2023 in the journal Public Health Reports. It was conducted by researchers from the University of California's Nutrition Policy Institute, Stanford University and Virginia Polytechnic Institute.
Good nutrition, and improved health, attendance, academics, and school climate are some of the benefits when schools offer meals at no charge to all students. California and Maine, followed by six other states, have already enacted legislation to provide daily meals at school to all K-12 public school students, at no charge regardless of family income level. According to tracking by the Food Research and Action Center, over half of the remaining states are working to pass School Meals for All legislation. Additionally, a bill has been offered at the federal level. Researchers at the Nutrition Policy Institute, Arizona State University, the University of Connecticut, Boise State University and Merrimack College developed a summary of the evidence on the benefits of universal school meal programs. The researchers who developed the synopsis work collaboratively on evaluations of new state School Meals for All programs.
Nutrition Policy's Institute's Celeste Felix will present at the 2023 California Resource and Recovery Association Conference about NPI's latest project evaluating how a large, urban school districts' transition to scratch cooking and using reusable serviceware can impact students' dietary intake and environmental sustainability. The conference is hosted by California's largest statewide recycling association and takes place in Burlingame, CA August 13-16, and Celeste will be co-presenting with Ben Schleifer from the Center for Environmental Health and Fremont Unified School District's recycling coordinator, Stephanie Willits on August 15 from 2:45 to 4:15 p.m. Ben, Stephanie, and Celeste will be highlighting the school districts' reusable tray and cutlery pilot project, which is part of a larger study, “Transition to Freshly-Prepared School Meals: Impacts on Meal Appeal, Student Participation, Intake, Food and Packaging Waste & School Finances,” funded by the US Department of Agriculture's Agriculture and Food Research Initiative, grant number 2020-68015-30736. This study is conducted by NPI, the UC Berkeley School of Public Health and FUSD in partnership with the Center for Environmental Health and StopWaste.
