The presence and mix of destinations is an important aspect of the built environment that may encourage or discourage physical activity. This study examined the association between the proximity and mix of neighbourhood destinations and physical activity.
Secondary analysis was undertaken on physical activity data from Western Australian adults (n=1394). These data were linked with geographical information systems (GIS) data including the presence and the mix of destinations located within 400 and 1500 m from respondents' homes. Associations with walking for transport and recreation and vigorous physical activity were examined.
Access to post boxes, bus stops, convenience stores, newsagencies, shopping malls, and transit stations within 400 m (OR 1.63-5.00) and schools, transit stations, newsagencies, convenience stores and shopping malls within 1500 m (OR 1.75-2.38) was associated with participation in regular transport-related walking. A dose-response relationship between the mix of destinations and walking for transport was also found. Each additional destination within 400 and 1500 m resulted in an additional 12 and 11 min/fortnight spent walking for transport, respectively.
Proximity and mix of destinations appears strongly associated with walking for transport, but not walking for recreation or vigorous activity. Increasing the diversity of destinations may contribute to adults doing more transport-related walking and achieving recommended levels of physical activity.
目的地的存在及其组合是建成环境的一个重要方面,可能会促进或抑制身体活动。本研究调查了邻里目的地的临近程度和组合与身体活动之间的关联。
对西澳大利亚成年人(n = 1394)的身体活动数据进行二次分析。这些数据与地理信息系统(GIS)数据相关联,包括距离受访者家400米和1500米范围内目的地的存在情况及其组合。研究了与出行步行、休闲步行和剧烈身体活动的关联。
距离400米范围内有邮箱、公交站、便利店、报刊亭、购物中心和地铁站(比值比1.63 - 5.00),以及距离1500米范围内有学校、地铁站、报刊亭、便利店和购物中心(比值比1.75 - 2.38),与参与定期出行相关步行有关。还发现目的地组合与出行步行之间存在剂量反应关系。400米和1500米范围内每增加一个目的地,分别会使出行步行时间每周增加12分钟和11分钟。
目的地的临近程度和组合似乎与出行步行密切相关,但与休闲步行或剧烈活动无关。增加目的地的多样性可能有助于成年人增加出行相关步行,并达到推荐的身体活动水平。
