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.
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.
Some US state laws require schools to provide certified physical education, or PE, teachers and a minimum amount of PE to support students in achieving 60 minutes of daily physical activity. However, adherence to these laws is low, especially in elementary schools. For example, in New York City elementary schools, adherence was only 4% in 2015. Researchers evaluated the effectiveness of PE Works, a multi-level intervention aimed at supporting elementary schools in implementing physical education (PE) in New York City. PE Works included three evidence-based interventions: providing certified PE teachers, training classroom teachers to lead PE, and implementing an audit and feedback system with coaching delivered by district-level staff. The study found that PE Works is most successful when school districts prioritize support for higher-need schools first, tailor support based on individual school needs, increase the importance of PE at the district and school level, build strong relationships between district and school staff, and provide ongoing coaching and involve parents in advocating for quality PE. The research suggests promising practices for scaling up similar interventions in school districts nationwide. Results were published in the International Journal of Behavioral Nutrition and Physical Activity by Hannah Thompson, Kristine Madsen and Maya Zamek from the University of California, Berkeley, Thomas McKenzie from San Diego State University and David Dzewaltowski from the University of Nebraska Medical Center. The research was funded by the National Heart Lung and Blood Institute, Grant 1K01HL151805.

Sufficient physical activity during childhood is critical to support children's current and future health. Schools across the country use fitness testing to assess and track student fitness, often reporting results to parents. A new study using data from over 570 thousand fourth- through 12th-grade racially/ethically and socioeconomically diverse students in New York City public schools demonstrates a positive association between student body mass index, a measurement for childhood obesity, and the trunk lift test–one of the most commonly used measures of flexibility. FITNESSGRAM® tests are one of the most widely-used tools in the U.S. to measure public school students' physical activity, yet few studies have assessed the validity and reliability of key components of the test–the trunk extension and the sit-and-reach–to measure flexibility. Researchers found that students with overweight or obesity consistently performed better on the trunk extension test compared to students with normal weight, suggesting that this test may not accurately measure students' flexibility. The study was published in the journal PloS ONE by Hannah Thompson from the University of California, Berkeley and University of California, Division of Agriculture and Natural Resources, Nutrition Policy Institute in collaboration with Andjelka Pavlovic from The Cooper Institute®, Emily D'Agostino from Duke University School of Medicine, Melanie Napier from the University of North Carolina at Chapel Hill, and Kevin Konty and Sophia Day from the New York City Department of Health and Mental Hygiene. This study was funded, in part, by the National Heart Lung and Blood Institute (NHLBI), Grant 1K01HL151805.
