Abstract
It is important to better understand factors associated with physical activity (PA) levels in adolescents in rural areas. Cross-sectional data were used to obtain self-reported PA levels among adolescents in a school-based intervention in fall 2018. Demographic data, environmental variables, and cardiovascular fitness (PACER score) were also measured. Analyses included a two-sample t-test, ANOVA, a Chi-square test, and a linear regression model. Participants included 3799 7th graders. Male (p < 0.0001), white (p < 0.0001), and healthy weight (p < 0.0001) participants reported more days of PA. The correlation between school physical education (PE) and PACER was modest (r = 0.27, p < 0.0001). Multiple linear regression model showed significant effects of school PE (p = 0.0011), gender (p < 0.0001), race (p < 0.0001), and weight category (p < 0.0001) on self-reported PA. The percentage of students reporting 60 min of PA for 5 (p < 0.0001) or 7 (p = 0.0307) days per week tended to be higher with increased days per week of school PE. Policy changes that increase PA and PE in middle schools may present opportunities to improve PA levels in adolescents, with emphasis on being inclusive and mindful of minority and female youth.Entities:

Details of how county- and school-level determinants were measured.
| Determinant | Description | Level | Scale | Description | Source |
|---|---|---|---|---|---|
| County-level Determinant | |||||
| Exercise Opportunities | Adequate access to locations for physical activity | County | 1–5 | “Access to Exercise Opportunities measures the percentage of individuals in a county who live reasonably close to a location for physical activity. Locations for physical activity are defined as parks or recreational facilities. Individuals are considered to have access to exercise opportunities if they: reside in a census block that is within a half mile of a park, reside in an urban census block that is within one mile of a recreational facility, or reside in a rural census block that is within 3 miles of a recreational facility” [ | County Health Rankings and Roadmaps |
