Data supporting "Weekend and weekday associations between the residential built environment and physical activity: findings from the ENABLE-London Study"

Data supporting “Weekend and weekday differences in associations between the residential built environment and physical activity: findings from the ENABLE-London Study”<br><br>The Examining Neighbourhood Activities in Built Living Environments in London (ENABLE London) study is a natural experiment. The primary aims were to examine whether objectively measured physical activity levels and body fatness showed change after two years, amongst individuals who moved to East Village compared with a control population who did not move to East Village. East Village is the former London 2012 Olympic Athletes’ Village repurposed to provide social, affordable and market-rent accommodation with high levels of walkability and close proximity to improved public transport. Other data collected include mental health and wellbeing, mode of travel and information on the participants’ built environment where they were living. A description of the baseline cohort, results from the main follow-up analysis and other secondary follow-up analyses of the data have already been published and are referenced below. These data relate to baseline analyses of the built environment data.<br><br>A cohort of 1278 adults aged 16+ who were looking to move into three different housing tenures in East Village was recruited between January 2013 and January 2016. Ethical approval was granted by City Road and Hampstead Review Board (REC reference number 12LO1031). The three housing tenures were social, intermediate (affordable market-rent/shared ownership/shared equity) and market-rent and were used as a marker of socio-economic status. Follow-up of participants was carried out two years after their baseline examination when approximately half the cohort had moved to East Village. Information was collected on participants at baseline and follow-up using computer-assisted self-complete questionnaires and physical examination (height, weight, body fat). Participants were asked to wear an accelerometer for seven consecutive days to objectively measure their physical activity. For those participants living in Greater London at baseline (n=1064), their residential locations were used to derive a range of built environment factors including walkability, distance to parks and accessibility to public transport.<br><br>The aims of this study were to assess whether at baseline, the residential built environment was associated with physical activity on week days and weekend days separately. Also, to explore two possible pathways in which the built environment may contribute to household-level socio-economic differences in physical activity levels.<br><br>The dataset available includes the variables listed below.

本数据集支撑论文《住宅建成环境与体力活动关联的周末与工作日差异：来自ENABLE-伦敦研究（ENABLE-London Study）的发现》。<br><br>伦敦建成居住环境邻里活动调研（ENABLE-London Study）为一项自然实验。其核心研究目的为：对比搬迁至东伦敦村（East Village）的人群与未搬迁至该区域的对照人群，分析两组人群在两年后客观测量的体力活动水平与体脂水平是否发生变化。东伦敦村原为2012年伦敦奥运会运动员村，经改造后可提供社会住房、可负担住房及市场租赁住房，具备高步行友好性，且紧邻优化后的公共交通站点。本次研究收集的其他数据还包括心理健康与福祉状况、出行方式，以及参与者居住环境的相关信息。针对该队列的基线特征、主要随访分析结果及其他次要随访分析均已发表，详见下文参考文献。本数据集对应建成环境数据的基线分析内容。<br><br>2013年1月至2016年1月期间，研究共招募了1278名16岁及以上的成年人，这些受试者均有意向东伦敦村的三类不同住房权属住房搬迁。该研究已通过City Road and Hampstead审查委员会的伦理审批（伦理审查编号：12LO1031）。三类住房权属分别为社会住房、中间型住房（可负担市场租金/共有产权/共享股权住房）及市场租赁住房，以此作为社会经济地位的标记指标。在基线评估完成两年后对受试者进行随访，此时约有一半队列成员已搬迁至东伦敦村。研究通过计算机辅助自填问卷与体格检查（测量身高、体重、体脂）收集基线与随访阶段的受试者信息。要求受试者连续7天佩戴加速度计（accelerometer），以客观测量其体力活动水平。对于基线时居住于大伦敦地区的受试者（n=1064），研究通过其居住地址推导了一系列建成环境相关指标，包括步行友好性、至最近公园的距离以及公共交通可达性。<br><br>本研究的目的为：评估基线时住宅建成环境分别与工作日、周末体力活动的关联；同时探索建成环境可能影响家庭层面体力活动水平的社会经济差异的两条潜在路径。<br><br>本次可用数据集包含下述变量。由于数据安全相关的签署同意协议限制，该数据集仅允许外部研究人员出于研究监测目的使用。若有研究者希望获取该数据集以重复或验证本研究分析，请联系伦敦大学圣乔治分校研究数据管理服务中心，邮箱地址：[e-mail]。<br><br><b>可用变量</b><br>人口统计学变量：性别、年龄组、种族群体、住房组别<br><br>基线住宅建成环境变量：步行友好性、至最近社区公园的距离、至最近区域公园的距离、至最近大都会公园的距离、公共交通可达性（伦敦交通局PTAL评分（PTAL score））<br>基线体力活动变量：工作日与周末经校正的日均步数、工作日与周末经校正的日均中等至高强度体力活动（moderate-to-vigorous physical activity, MVPA）时长。
