This study investigated the association of built, natural and social environment variables with the practice of physical activity (PA) during leisure time and commuting.
Household interviews were carried out with a representative sample of individuals aged 18 years or older from a municipality in southern Brazil. PA was measured by the International Physical Activity Questionnaire, and households were georeferenced with a 500-m buffer.
Few associations between environmental variables and PA practice were identified. Only proximity to the seafront, presence of private gyms or sports clubs and higher average monthly income of the household head were associated with the practice of PA. In addition, there were inconsistencies in the findings showing that the associations varied based on the intensity and modality of PA within the same domain.
This study provides evidence on the lack of association between objective environmental measures and the practice of PA. Although there were few significant results and the presence of inconsistencies in the findings, some environmental variables were associated with a more frequent practice of PA.
本研究旨在调查建成环境、自然环境和社会环境变量与闲暇时间和通勤时进行身体活动（PA）的实践之间的关联。
对来自巴西南部一个城市的年龄在 18 岁及以上的代表性个体家庭进行入户访谈。通过国际体力活动问卷（International Physical Activity Questionnaire）来测量 PA，并用 500 米缓冲区对家庭进行地理定位。
仅发现环境变量与 PA 实践之间存在少量关联。只有靠近海滨、私人健身房或体育俱乐部的存在以及家庭户主的平均月收入较高与 PA 实践相关。此外，研究结果存在不一致性，表明在同一领域内，PA 的强度和模式的变化会导致关联发生变化。
本研究提供了客观环境测量与 PA 实践之间缺乏关联的证据。尽管存在少数显著结果和研究结果存在不一致性，但一些环境变量与更频繁的 PA 实践相关。
