摘要
BACKGROUND This study examined differences in students%26apos; time spent in physical activity (PA) across secondary schools in rural, suburban, and urban environments and identified the environment-level factors associated with these between school differences in students%26apos; PA. METHODS Multilevel linear regression analyses were used to examine the environment- and student-level characteristics associated with time spent in PA among grades 9 to 12 students attending 76 secondary schools in Ontario, Canada, as part of the SHAPES-Ontario study. This approach was first conducted with the full data set testing for interactions between environment-level factors and school location. Then, school-location specific regression models were run separately. RESULTS Statistically significant between-school variation was identified among students attending urban (sigma 20=8959.63 [372.46]), suburban (sigma 20=8918.75 [186.20]), and rural (sigma 20=9403.17 [203.69]) schools, where school-level differences accounted for 4.0%, 2.0%, and 2.1% of the variability in students%26apos; time spent in PA, respectively. Students attending an urban or suburban school that provided another room for PA or was located within close proximity to a shopping mall or fast food outlet spent more time in PA. CONCLUSION Students%26apos; time spent in PA varies by school location and some features of the school environment have a different impact on students%26apos; time spent in PA by school location. Developing a better understanding of the environment-level characteristics associated with students%26apos; time spent in PA by school location may help public health and planning experts to tailor school programs and policies to the needs of students in different locations.
