居民区的环境特征被认为与居民的身体活动水平有关，但许多研究报告只报告了微弱或模棱两可的联系。我们的理论认为，这可能是因为邻里特征对活动地点的影响大于活动数量。通过对英国青少年的抽样调查，我们考察了居家邻居对体育活动的支持在活动量和活动发生地点离家近程度两方面的作用。对居住在英国布里斯托尔市及周边地区的967名青少年的数据进行了分析。每个参与者在学期期间都佩戴了7天的加速计和GPS设备。这些数据被整合到一个地理信息系统中，其中包含有关参与者居住的居民区和环境支持程度的信息。然后，我们确定了青少年在居家社区内进行的不同强度的校外活动的数量，并研究了这与居家社区支持之间的关系。我们发现，生活在支持度较低的社区并不会对青少年的体力活动产生负面影响。事实上，这些参与者记录的活动量(例如，周末每天20.5分钟的适度活动)与那些支持较多的社区的参与者(每天18.6分钟)相似。然而，青少年在家中活动的数量确实因支持程度的不同而有所不同；那些生活在支持度较低的地区的青少年在家中记录活动的几率较低。这在所有强度的运动中都能观察到，包括久坐、轻度、中度和剧烈运动。我们的研究结果表明，家庭周围邻居的支持对身体活动地点的影响可能比体育活动的数量更大。这一发现与过去20年来推动这一研究领域的身体活动的社会生态模型的前提不一致，并对未来的研究产生了影响，因为通过简单地衡量活动量，我们可能低估了环境对身体活动行为的影响。
Environmental characteristics of home neighbourhoods are hypothesised to be associated with residents’ physical activity levels, yet many studies report only weak or equivocal associations. We theorise that this may be because neighbourhood characteristics influence the location of activity more than the volume. Using a sample of UK adolescents, we examine the role of home neighbourhood supportiveness for physical activity, both in terms of volume of activity undertaken and a measure of proximity to home at which activity takes place. Data were analysed from 967 adolescents living in and around the city of Bristol, UK. Each participant wore an accelerometer and a GPS device for 7 days during school term time. These data were integrated into a Geographical Information System containing information on the participants’ home neighbourhoods and measures of environmental supportiveness. We then identified the amount of out-of-school activity of different intensities that adolescents undertook inside their home neighbourhood and examined how this related to home neighbourhood supportiveness. We found that living in a less supportive neighbourhood did not negatively impact the volume of physical activity that adolescents undertook. Indeed these participants recorded similar amounts of activity (e.g. 20.5 mins per day of moderate activity at weekends) as those in more supportive neighbourhoods (18.6 mins per day). However, the amount of activity adolescents undertook inside their home neighbourhood did differ according to supportiveness; those living in less supportive locations had lower odds of recording activity inside their home neighbourhood. This was observed across all intensities of activity including sedentary, light, moderate, and vigorous. Our findings suggest that the supportiveness of the neighbourhood around home may have a greater influence on the location of physical activity than the volume undertaken. This finding is at odds with the premise of the socio-ecological models of physical activity that have driven this research field for the last two decades, and has implications for future research, as by simply measuring volumes of activity we may be underestimating the impact of the environment on physical activity behaviours.
