Few longitudinal residential relocation studies have explored associations between urban form and physical activity, and none has used the Space Syntax theory. Using a Canadian longitudinal dataset (n = 5944), we estimated: (1) differences in physical activity between non-movers, and those relocating to neighbourhoods with less or more integrated street layouts, and; (2) associations between changes in street layout integration exposure and differences in physical activity. Adjusting for covariates, we found relative to non-movers, those who moved to more integrated neighbourhoods undertook significantly (p < .05) more leisure walking (27.3 min/week), moderate-intensity (45.7 min/week), and moderate-to-vigorous intensity physical activity (54.4 min/week). Among movers, a one-unit increase in the relative change in street integration exposure ([Street integration at follow-up-street integration at baseline]/street integration at baseline) was associated with a 7.5 min/week increase in leisure walking. Our findings suggest that urban design policies that improve neighbourhood street integration might encourage more physical activity in adults.
几乎没有纵向住宅迁移研究探讨城市形态与身体活动之间的关系，也没有研究使用空间句法理论。本研究使用加拿大纵向数据集（n=5944），估计：（1）非迁移者与迁移到街道布局连通性较差或较好的社区的人群之间身体活动的差异；（2）街道布局连通性暴露变化与身体活动差异之间的关联。调整了协变量后，我们发现与非迁移者相比，迁移到连通性较好的社区的人群，其休闲步行（27.3 分钟/周）、中等强度（45.7 分钟/周）和中等到剧烈强度的身体活动（54.4 分钟/周）明显更多（p<0.05）。在迁移者中，街道连通性暴露相对变化（[随访时的街道连通性-基线时的街道连通性]/基线时的街道连通性）每增加一个单位，休闲步行的时间就会增加 7.5 分钟/周。本研究结果表明，改善社区街道连通性的城市设计政策可能会鼓励成年人增加身体活动。
