Walking to and from school contributes to total physical activity levels. This study investigated whether perceived and actual neighborhood features were associated with walking to or from school among adolescent girls.
A sample of geographically diverse eighth-grade girls (N = 890) from the Trial of Activity in Adolescent Girls (TAAG) study living within 1.5 miles of their middle school was recruited. Participants completed a self-administered survey on their neighborhood and walking behavior. Geographic information system data were used to assess objective neighborhood features. Nested multivariable logistic regression analyses were conducted to determine the contribution of perceived and objective measures of walking to or from school.
Fifty-six percent (n = 500) of the girls walked to or from school for at least 1 d in a week. White (42%) girls walked more frequently than Hispanic (25%) and African American (21%) girls. Girls were nearly twice as likely to walk to or from school if they perceived their neighborhoods as safe and perceived that they had places they liked to walk, controlling for other potential confounders. In addition, girls who lived closer to school, had more active destinations in their neighborhood, and had smaller-sized blocks were more likely to walk to or from school than those who did not.
Safety, land use, and school location issues need to be considered together when designing interventions to increase walking to and from school.
步行上下学有助于提高青少年的总体身体活动水平。本研究旨在调查青少年女孩对邻里环境特征的感知和实际感知是否与步行上下学有关。
从“青少年女孩活动试验”(TAAG)研究中招募了居住在距离中学 1.5 英里范围内的具有不同地理特征的八年级女孩(N=890)。参与者完成了关于邻里环境和步行行为的自我管理调查。利用地理信息系统数据评估了客观的邻里环境特征。采用嵌套多变量逻辑回归分析来确定感知和客观的上下学步行测量值的贡献。
56%(n=500)的女孩每周至少有 1 天步行上下学。白人(42%)女孩比西班牙裔(25%)和非裔美国女孩(21%)更频繁地步行上下学。在控制其他潜在混杂因素的情况下,如果女孩认为自己的邻里环境安全,并且认为有自己喜欢散步的地方,那么她们上下学步行的可能性几乎是其他女孩的两倍。此外,那些居住离学校更近、邻里活动目的地更多以及街区面积更小的女孩比其他女孩更有可能步行上下学。
在设计增加步行上下学的干预措施时,需要综合考虑安全、土地利用和学校位置等问题。
