在成人研究中，社区步行性已被公认为是身体活动的建筑环境相关因素中的一个重要结构。对这种关联的研究只是最近才扩展到青少年，目前的经验证据并不一致。本研究调查了社区步行能力和社区社会经济地位（SES）是否与比利时青少年的体育活动有关，以及社区步行能力和体育活动之间的关联是否受社区SES和性别的影响。在根特（比利时），32个街区被选中的基础上，基于GIS的步行能力和SES来自人口普查数据。共有637名青少年（年龄13-15岁，49.6%为男性）参与了研究。体力活动进行了评估，使用加速度计和佛兰芒体力活动问卷。为了分析邻里步行适宜性、邻里社会经济地位与个人体力活动之间的关系，进行了多变量多水平回归分析。只有在低SES社区，社区步行能力与基于加速度计的中度到剧烈的身体活动呈正相关，平均活动水平以计数/分钟表示。对于积极的交通往返学校，骑自行车的交通在闲暇时间和运动在闲暇时间没有关联，也没有与邻里的可步行性，与邻里SES被发现。对于步行交通在闲暇时间与邻里SES的负相关被发现。性别没有缓和邻里的可步行性和SES与青少年身体活动的关联。社区步行能力与加速度计为基础的身体活动，只有在青少年男孩和女孩生活在低SES社区。建筑环境与青少年身体活动的关系可能取决于环境。
In adult research, neighborhood walkability has been acknowledged as an important construct among the built environmental correlates of physical activity. Research into this association has only recently been extended to adolescents and the current empirical evidence is not consistent. This study investigated whether neighborhood walkability and neighborhood socioeconomic status (SES) are associated with physical activity among Belgian adolescents and whether the association between neighborhood walkability and physical activity is moderated by neighborhood SES and gender. In Ghent (Belgium), 32 neighborhoods were selected based on GIS-based walkability and SES derived from census data. In total, 637 adolescents (aged 13-15 year, 49.6% male) participated in the study. Physical activity was assessed using accelerometers and the Flemish Physical Activity Questionnaire. To analyze the associations between neighborhood walkability, neighborhood SES and individual physical activity, multivariate multi-level regression analyses were conducted. Only in low-SES neighborhoods, neighborhood walkability was positively associated with accelerometer-based moderate to vigorous physical activity and the average activity level expressed in counts/minute. For active transport to and from school, cycling for transport during leisure time and sport during leisure time no association with neighborhood walkability nor, with neighborhood SES was found. For walking for transport during leisure time a negative association with neighborhood SES was found. Gender did not moderate the associations of neighborhood walkability and SES with adolescent physical activity. Neighborhood walkability was related to accelerometer-based physical activity only among adolescent boys and girls living in low-SES neighborhoods. The relation of built environment to adolescent physical activity may depend on the context.
