为了更准确地量化邻里环境对成年人体力活动 (PA) 的潜在影响，重要的是要比较一天或一周中成年人更有可能与不太可能呆在邻里并利用其 PA 资源的时段之间的环境与 PA 关联。我们研究了来自 10 个国家的成年人中，客观评估的邻里环境属性与中度至剧烈体力活动 (MVPA) 之间的关联是否因一天中的不同时间和一周中的不同日期而变化。第二个目的是研究这些协会是否因就业状况、性别和城市而异。这项横断面研究包括来自 10 个国家 14 个城市的 6,712 名成年人，他们接受了 ≥1 天的有效加速计评估 MVPA，并获得了家庭周围 0.5 公里和 1 公里街道网络缓冲区内社会人口统计和客观评估环境特征的完整信息。加速度计测量（MVPA 分钟/小时）是针对从清晨到深夜/夜间的六个时间段（分别针对工作日和周末）创建的。使用广义加性混合模型估计关联性。一天中的时间、一周中的某一天、性别和就业状况是环境-MVPA 关联的重要调节因素。对于就业女性和男性，无论其就业状况如何，土地利用组合与 MVPA 呈正相关。 MVPA 与净住宅密度、交叉口密度和土地利用组合之间的正相关性在工作日的上午以及工作日和周末的下午/晚上时段更强。无论一周中的哪一天，公园数量与 MVPA 之间的关联在早上和下午/晚上都更强。公共交通密度在周末与 MVPA 呈正相关，而在工作日的早晨和傍晚则观察到更强的影响。本研究表明，成年人日常活动的空间和时间限制是决定邻里属性对 PA 影响的重要因素。考虑特定时间的关联对于更好地表征邻近环境对 PA 的影响程度非常重要。未来的研究需要考察其他类型日常生活中心（例如工作场所）周围区域的建筑环境特征对解释成年人在一天中特定时间的 PA 的贡献。
To more accurately quantify the potential impact of the neighbourhood environment on adults’ physical activity (PA), it is important to compare environment-PA associations between periods of the day or week when adults are more versus less likely to be in their neighbourhood and utilise its PA resources. We examined whether, among adults from 10 countries, associations between objectively-assessed neighbourhood environment attributes and moderate-to-vigorous physical activity (MVPA) varied by time of the day and day of the week. The secondary aim was to examine whether such associations varied by employment status, gender and city. This cross-sectional study included 6,712 adults from 14 cities across 10 countries with ≥1 day of valid accelerometer-assessed MVPA and complete information on socio-demographic and objectively-assessed environmental characteristics within 0.5 and 1 km street-network buffers around the home. Accelerometer measures (MVPA min/h) were created for six time periods from early morning until late evening/night, for weekdays and weekend days separately. Associations were estimated using generalized additive mixed models. Time of the day, day of week, gender and employment status were significant moderators of environment-MVPA associations. Land use mix was positively associated with MVPA in women who were employed and in men irrespective of their employment status. The positive associations between MVPA and net residential density, intersection density and land use mix were stronger in the mornings of weekdays and the afternoon/evening periods of both weekdays and weekend days. Associations between number of parks and MVPA were stronger in the mornings and afternoon/evenings irrespective of day of the week. Public transport density showed consistent positive associations with MVPA during weekends, while stronger effects on weekdays were observed in the morning and early evenings. This study suggests that space and time constraints in adults’ daily activities are important factors that determine the impact of neighbourhood attributes on PA. Consideration of time-specific associations is important to better characterise the magnitude of the effects of the neighbourhood environment on PA. Future research will need to examine the contribution of built environment characteristics of areas surrounding other types of daily life centres (e.g., workplaces) to explaining adults’ PA at specific times of the day.
