School Food and Physical Activity Environment: A Longitudinal Analysis of four School Districts in New Jersey

This study analyzes changes in school food and physical activity (PA) environments across four New Jersey school districts between 2010 and 2015. While PA environments remained largely unchanged, there was a noticeable increase in healthy food options in vending machines and school lunches. However, the study found only modest reductions in unhealthy food offerings. The research suggests that policy-driven interventions are effective in improving school nutrition but require more robust enforcement and community engagement.
