Background:
An obesogenic environment that limits physical activity (PA) contributes to rising childhood obesity rates. Schools play a pivotal role in providing structured and unstructured outdoor opportunities for PA. This setting allows policy-driven assessments for potential health and well-being policy modification.
Methods:
In-school elementary PA was assessed using hip-worn accelerometers over five consecutive school days (N = 408 students). Teachers recorded information for physical education (P.E.) and recess, which was analyzed using accelerometry software and MANOVA in SPSS.
Results:
Students failed to meet the recommended 150 min of in- school moderate-to-vigorous PA per week. Significant differences in PA during recess and P.E. were found based on sex, race, academic grade, and presence of a P.E. instructor. This Implications for School Health Policy, Practice, and Equity. Improving school health requires not just meeting mandated PA minutes but ensuring equitable, high-quality opportunities supported by trained P.E. staff. Strengthening accountability, providing inclusive programming, and using objective monitoring can help schools reduce disparities and promote healthier active learning environments.
Conclusions:
These findings highlight the need for improved assessment models and targeted interventions for improved policy adherence. Delivering effective, inclusive PA programs is critical for fostering healthier environments and ensuring children have equitable opportunities for PA during school.
