在建筑环境和体育活动的研究中，地理分析单位的选择通常局限于只有一小部分体育活动可以实际进行的家庭社区。这项研究的目的是调查人们在离家很远的地方进行体育活动，以及这种距离如何因个人和社区特征而变化。这是一项基于人口的横断面研究，研究对象是英格兰西北部地区195名年龄在18岁至91岁之间的人，他们聚集在60个地区（约125户家庭的小地理区域）。个人社会人口统计数据通过计算机辅助个人访谈收集，身体活动通过加速度计和全球定位系统（GPS）数据进行表征。在户外进行轻度、中度和剧烈体力活动（LMVPA）的时间段的位置与家庭周围的社区和离家的距离有关。60%的户外LMVPA发生在最近的家庭社区之外（800米缓冲区）。中位LMVPA水平的离家距离因性别（p < 0.05）、家庭位置、面积剥夺和汽车拥有量（均p < 0.001）而异。客观测量的身体活动似乎因参与者特征和家庭位置而有明显差异，尽管在许多情况下，很大一部分是在家庭社区之外进行的，这表明对离家近的社区的描述将无法正确捕捉环境对身体活动的影响。
The choice of geographical unit of analysis in studies of the built environment and physical activity has typically been restricted to the home neighbourhood where only a small proportion of physical activity may actually be undertaken. This study aimed to examine the distance from home at which physical activity takes place and how this varies by personal and neighbourhood characteristics. A cross-sectional, population based study of 195 people in the North West region of England, aged 18 to 91 years, clustered in 60 localities (small geographical areas of ~125 households). Individual socio-demographic data were collected by computer-aided personal interviews and physical activity was characterised by accelerometer and Global Positioning System (GPS) data. The locations of periods of light, moderate and vigorous intensity physical activity (LMVPA) undertaken outdoors were linked to measures of the neighbourhood around the home and distance from home. Sixty per cent of outdoors LMVPA took place outside of the proximal home neighbourhood (800 m buffer). Distances from home where median levels of LMVPA were undertaken varied by gender (p < 0.05), home location, area deprivation, and car ownership (all p < 0.001). Objectively measured physical activity appears to vary appreciably by participant characteristics and home location, although for many settings a large proportion is undertaken outside of the home neighbourhood, suggesting the characterisation of neighbourhoods close to home will fail to properly capture the environmental influences on physical activity.
