New study identifies a promising combination of school-based Supplemental Nutrition Assistance Program-Education interventions for improving student fitness

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.
