The School Environment and Physical and Social‐Emotional Well‐Being: Implications for Students and School Employees.

Background: The school environment, consisting of the physical environment and social‐emotional climate (SEC), plays a crucial role in both student and employee health; however, there is a lack of recent literature synthesizing school environment interventions in K‐12 settings. We describe updated evidence about school environment interventions to support K‐12 student and employee health in the United States. Methods: A 2‐phase search included a review of reviews (2010‐2018), followed by a search for individual articles (2010‐2020) that targeted school physical environment and/or SEC to address physical activity (PA) and/or nutrition. We also investigated how nutrition and PA interventions with an SEC component improves social‐emotional and/or mental health outcomes. Because research on dietary and PA behaviors for school employees is limited; we included studies on other worksites (eg, hospitals and offices) to provide insight for school employees. Findings: We identified 40 articles describing 40 unique studies and 45 interventions and grouped them by intervention type. Physical environment interventions demonstrated significant and positive nutrition and PA behavioral outcomes for students; outcomes among employees were mixed. Interventions with SEC components reported improvements in some mental health outcomes. Implications: The school environment can affect dietary and PA behaviors as well as mental health for students and employees. Conclusions: Establishing healthy school environments can support student and employee PA, dietary behaviors, and mental health. [ABSTRACT FROM AUTHOR]
