城市交通系统的重新配置已成为解决身体活动不足问题的全民干预措施的前沿。然而，这些干预措施的有效性仍然没有得到充分研究，特别是在发展中国家。使用自我报告的身体活动数据从干预前和干预后的时期，本研究探讨了快速公交（BRT）和完整的街道实施对步行和骑自行车水平的集水区居民在墨西哥城的影响。倾向分数匹配应用于控制社会人口统计学时，评估干预效果步行运输，步行娱乐，骑自行车运输。平均而言，生活在干预后条件下的个人每周倾向于多步行29分钟。然而，对骑自行车运输的干预效果是微不足道的。使用聚类技术，在不同的社会人口群体的干预效果进行评估。受教育程度低的妇女步行出行的次数增加最多。以高等教育为特征的社会人口学集群在休闲步行方面的经验得到了改善。总体而言，BRT的实施和街景改善增强了身体活动，特别是步行;这些干预措施的影响在不同的社会人口亚组中各不相同。(C)2017爱思唯尔有限公司版权所有
The reconfiguration of urban transportation system has emerged at the forefront of population-wide interventions to tackle physical inactivity. However, the effectiveness of these interventions remains understudied, especially in developing countries. Using self reported physical activity data from pre- and post-intervention periods, this study examines the impact of bus rapid transit (BRT) and Complete Street implementation on walking and cycling levels of catchment area residents in Mexico City. Propensity score matching is applied to control for sociodemographics when evaluating intervention effects on walking for transport, walking for recreation, and cycling for transport. On average, individuals living in post-intervention conditions tend to achieve 29 min more of walking for transport per week. However, the intervention effect on cycling for transport is insignificant. Using clustering techniques, intervention effects are evaluated across different sociodemographic groups. Women with low education experience the greatest increases in walking for transport. Sociodemographic clusters characterized by higher education experience improvements in recreational walking. Overall, BRT implementation and streetscape improvements enhance physical activity, specifically walking; and the impact of these interventions vary across different sociodemographic subgroups.
