Residents of socioeconomically disadvantaged neighbourhoods are more likely to walk for transport than their counterparts in advantaged neighbourhoods; however, the reasons for higher rates of transport walking in poorer neighbourhoods remain unclear. We investigated this issue using data from the HABITAT study of physical activity among 11,037 mid-aged residents of 200 neighbourhoods in Brisbane, Australia. Using a five-step mediation analysis and multilevel regression, we found that higher levels of walking for transport in disadvantaged neighbourhoods was associated with living in a built environment more conducive to walking (i.e. greater street connectivity and land use mix) and residents of these neighbourhoods having more limited access to a motor vehicle. The health benefits that accrue to residents of disadvantaged neighbourhoods as a result of their higher levels of walking for transport might help offset the negative effects of less healthy behaviours (e.g. smoking, poor diet), thus serving to contain or reduce neighbourhood inequalities in chronic disease.

:与处于有利地位的社区的居民相比,处于社会经济劣势的社区的居民更有可能步行运输;但是,在较贫困的社区中提高交通运输速度的原因仍不清楚。我们使用了HABITAT对澳大利亚布里斯班200个社区的11,037名中年居民进行的体育活动研究的数据,对这一问题进行了调查。通过五步中介分析和多级回归,我们发现弱势社区中较高水平的步行交通与居住在更有利于步行的建筑环境中(即更大的街道连通性和土地使用结构)以及这些社区的居民有关对汽车的访问受到更多限制。较高的步行运输水平为弱势社区居民带来的健康益处可能有助于抵消不良健康行为(例如吸烟,饮食不良)的负面影响,从而遏制或减少慢性病中的社区不平等现象。
