Neighborhood structural factors are associated with greater feasibility of youth active travel and thus, greater levels of physical activity. However, limited prior work has addressed walkability factors specific to the school neighborhood related to adolescent physical activity during the school day. Therefore, the purpose of this study was to examine the relationship between two school neighborhood walkability factors (neighborhood density and neighborhood age) and school-related adolescent moderate-to-vigorous physical activity (MVPA). We analyzed cross-sectional data from the Family Life, Activity, Sun, Health, and Eating (FLASHE) study for 1,183 adolescents ages 12-17 years. Separate linear regression models assessed the association between both school-neighborhood density and school-neighborhood age (i.e., population/housing unit density and age of buildings/units, respectively, within a 400m buffer around school address) and adolescent school-related MVPA, adjusting for age, sex, race/ethnicity, weight status, urban/rural environment and parent MVPA. School-neighborhood density (8.62, 95% CI: 0.70, 16.53) and school-neighborhood age (6.38, 95% CI: -0.29, 13.05) were both positively associated with school-related MVPA, although the neighborhood age-MVPA association observed was not statistically significant. When seeking to improve physical activity among adolescents, school neighborhood structural factors that support physical activity throughout a school day should be considered. Unfortunately, macro-scale environmental features such as these are not easily modified. Thus, these findings should be used to inform additional research related to school-neighborhood walkability and adolescent participation in physical activity.
社区结构因素与青少年积极出行的更高可行性相关，因此也与更高水平的身体活动相关。然而，先前的研究工作有限，尚未涉及与青少年在校期间身体活动相关的学校周边适宜步行因素。因此，本研究的目的是检验两个学校周边适宜步行因素（社区密度和社区年代）与学校相关的青少年中等到剧烈身体活动（MVPA）之间的关系。我们分析了来自家庭生活、活动、阳光、健康和饮食（FLASHE）研究的1183名12 - 17岁青少年的横断面数据。单独的线性回归模型评估了学校周边密度和学校周边年代（即分别为学校地址周围400米缓冲区内的人口/住房单元密度和建筑物/单元的年代）与青少年学校相关的MVPA之间的关联，并对年龄、性别、种族/族裔、体重状况、城乡环境和家长的MVPA进行了调整。学校周边密度（8.62，95%置信区间：0.70，16.53）和学校周边年代（6.38，95%置信区间：-0.29，13.05）均与学校相关的MVPA呈正相关，尽管观察到的社区年代与MVPA之间的关联无统计学意义。当寻求提高青少年的身体活动水平时，应考虑支持全天身体活动的学校周边结构因素。不幸的是，诸如此类的宏观环境特征不易改变。因此，这些研究结果应用于为与学校周边适宜步行性和青少年参与身体活动相关的进一步研究提供信息。
