Many aspects of the built, physical environment have been shown to be associated with physical activity, but little research has focused on the unique circumstances and urban form of the suburban environment. The following analyses explore the associations between features of the built environment and components of overall physical activity, after accounting for neighborhood variability using hierarchical linear modeling.
These analyses utilized regionally-specific Geographic Information Systems data along with health measures collected from the 2007-8 Canadian Community Health Survey. Linear and logistic regression models explored the associations between measures of the built environment with leisure-time and transport-related physical activity.
Respondents living with the highest number of intersections were more likely to engage in walking or cycling for leisure (OR: 1.85 CI 95%: 1.23-2.78), and in general, those living in areas with higher residential density were more likely to engage in active modes of transportation (OR: 2.67, CI 95%: 1.34-5.34).
Further analyses are necessary to clarify the extent to which modifications to such features of the built environment may improve physical activity participation in similar suburban communities.
已表明建成的物质环境的许多方面与身体活动有关，但很少有研究关注郊区环境的独特情况和城市形态。以下分析在使用分层线性模型考虑邻里差异后，探讨建成环境特征与总体身体活动各组成部分之间的关联。
这些分析利用了特定区域的地理信息系统数据以及从2007 - 2008年加拿大社区健康调查中收集的健康指标。线性和逻辑回归模型探讨了建成环境指标与休闲时间及交通相关身体活动之间的关联。
居住在交叉路口数量最多地区的受访者更有可能进行休闲步行或骑自行车（比值比：1.85，95%置信区间：1.23 - 2.78），总体而言，居住在住宅密度较高地区的人更有可能采用积极的交通方式（比值比：2.67，95%置信区间：1.34 - 5.34）。
有必要进行进一步分析，以阐明对建成环境此类特征的改变在多大程度上可提高类似郊区社区的身体活动参与度。
