The physical neighbourhood environment may influence adults' sedentary behaviour. Yet, most studies examining the association between the physical neighbourhood environment and sedentary behaviour rely on self-reported data of either the physical neighbourhood environment and/or sedentary behaviour. The aim of this study was to investigate the associations between objectively measured physical environmental neighbourhood factors and accelerometer-determined total sedentary time in adults.
In total, 219 Dutch and 128 Belgian adults (mean age ± SD: 55.8 ± 15.4 years) were recruited between March and August 2014 as part of the European SPOTLIGHT project. Physical environmental neighbourhood factors, grouped into eight domains, i.e. walking, cycling, public transport, aesthetics, land use mix, grocery stores, food outlets and recreational facilities, were assessed using the SPOTLIGHT Virtual Audit Tool. Sedentary time was collected using ActiGraph GT3X+ accelerometers. General linear mixed models were conducted to examine associations between physical environmental neighbourhood factors and total sedentary time.
Participants were sedentary, on average, for 542.9 min/day (SD: 84.3), or 9.1 h/day. None of the examined physical environmental neighbourhood factors were significantly related to total sedentary time.
Our findings do not support associations of objectively measured physical environmental neighbourhood factors with adults' objectively sedentary time in Dutch and Belgian adults. More research on sedentary behaviours in settings such as the home and work setting is needed to examine the influence of more specific physical environmental factors on these context-specific sedentary behaviours.
邻里物理环境可能会影响成年人的久坐行为。然而，大多数研究邻里物理环境与久坐行为之间关联的研究，所依赖的是邻里物理环境和/或久坐行为的自我报告数据。本研究的目的是调查客观测量的邻里物理环境因素与通过加速度计确定的成年人总久坐时间之间的关联。
作为欧洲SPOTLIGHT项目的一部分，2014年3月至8月期间共招募了219名荷兰成年人和128名比利时成年人（平均年龄±标准差：55.8±15.4岁）。使用SPOTLIGHT虚拟审核工具评估邻里物理环境因素，这些因素分为八个领域，即步行、骑行、公共交通、美观程度（美学）、土地利用混合度、杂货店、食品店和娱乐设施。使用ActiGraph GT3X+加速度计收集久坐时间。采用一般线性混合模型来研究邻里物理环境因素与总久坐时间之间的关联。
参与者平均每天久坐542.9分钟（标准差：84.3），即每天9.1小时。所研究的邻里物理环境因素中，没有一个与总久坐时间显著相关。
我们的研究结果不支持在荷兰和比利时成年人中，客观测量的邻里物理环境因素与成年人客观久坐时间之间存在关联。需要对家庭和工作场所等环境中的久坐行为进行更多研究，以考察更具体的物理环境因素对这些特定环境下久坐行为的影响。
