Studies investigating the association between spatial accessibility to environmental resources from the various places a person visits during daily activities and use of corresponding resources often do not account for potential biases related to selective daily mobility. This bias occurs when accessibility is also measured from places intentionally visited to access the resources of interest. The aim of this study was to examine associations between spatial accessibility to sports facilities from multiple places and sport practice while addressing the selective daily mobility bias.
The second wave of the RECORD Cohort was used to examine the relationship between the spatial accessibility to sport facilities and the practice of three sport categories (swimming, racket, and team sports), using multilevel linear probability models (n = 5327 participants) adjusted for individual and contextual characteristics. Street network distance to the nearest sport facility was considered as a measure of spatial accessibility [from the residence; from the residence and workplace; from all visited locations (full activity space), biased; and from all locations excluded those visited for sports (truncated activity space), corrected].
The residential and residential-workplace accessibility to facilities was not associated with sport practice. The spatial accessibility to facilities from all places visited (full activity space) was associated with the practice of the three categories of sports (biased relationships). After correcting the bias (truncated activity space), the strength of the relationships was markedly reduced. An association remained only for swimming sports.
This study underlines the need to account for selective daily mobility bias when determining spatial accessibility to resources from the various places visited. Such bias, if not addressed, may result in overestimated associations between spatial accessibility and use, leading to potentially erroneous conclusions in terms of planning.
研究人员调查了一个人在日常活动中访问的不同地点的环境资源的空间可达性与使用相应资源之间的关联，这些研究通常没有考虑到与选择性日常出行相关的潜在偏差。当可达性也从为获取感兴趣的资源而有意访问的地点进行测量时，就会出现这种偏差。本研究的目的是在解决选择性日常出行偏差的情况下，检验从多个地点到体育设施的空间可达性与运动实践之间的关联。
利用 RECORD 队列的第二波数据，使用多层次线性概率模型（n=5327 名参与者），调整个体和环境特征，检验与三种运动类型（游泳、球拍和团队运动）相关的体育设施空间可达性与运动实践之间的关系。街道网络距离最近的体育设施被认为是空间可达性的衡量标准[从居住地；从居住地和工作场所；从所有访问地点（全活动空间），存在偏差；从所有访问地点中排除那些为运动而访问的地点（截断活动空间），纠正]。
设施的居住和居住-工作场所可达性与运动实践无关。从所有访问地点（全活动空间）的设施可达性与三种运动类别的实践相关（存在偏差关系）。在纠正偏差（截断活动空间）后，这些关系的强度显著降低。只有游泳运动与这种可达性仍存在关联。
本研究强调了在确定从各种访问地点获得的资源的空间可达性时，需要考虑选择性日常出行的偏差。如果不加以解决，这种偏差可能会导致空间可达性与使用之间的关联被高估，从而在规划方面产生潜在的错误结论。
