目的在考虑家庭、工作场所和通勤路线环境的情况下，研究环境暴露于外卖快餐店、外卖食品消费与体重之间的关系。设计基于人群的横断面研究，使用个体参与者的饮食和体重数据，以及食物环境暴露的客观指标。参与者：参加英国剑桥郡芬兰研究的在职成年人（n=5442，年龄29-62岁），他们提供了家庭和工作地址以及通勤偏好。利用地方当局提供的个人环境领域（家中、工作场所和通勤路线（家和工作场所之间的最短路线））以及所有三个领域的综合暴露数据，得出了外卖食品出口暴露的数据。暴露被分成四份(Q)；Q1受到的影响最小，Q4受到的影响最大。主要结果测量：使用食物频率问卷、测量的体重指数和世界卫生组织定义的体重指数截断值，自我报告外卖类食品的消费（克/天；披萨、汉堡、油炸食品和薯条）。结果在多元线性回归模型中，外卖门店暴露与外卖消费呈正相关。在家庭、工作和通勤路线中，工作环境中的关联最强(Q4 vs Q1； β系数=5.3 g/day， 95%置信区间为1.6 ~ 8.7；P
Objectives To examine the association between environmental exposure to takeaway food outlets, takeaway food consumption, and body weight, while accounting for home, work place, and commuting route environments.Design Population based, cross sectional study, using data on individual participants' diet and weight, and objective metrics of food environment exposure.Participants Working adults participating in the Fenland Study, Cambridgeshire, UK (n=5442, aged 29-62 years), who provided home and work addresses and commuting preferences. Takeaway food outlet exposure was derived using data from local authorities for individual environmental domains (at home, at work, and along commuting routes (the shortest route between home and work)), and for exposure in all three domains combined. Exposure was divided into quarters (Q); Q1 being the least exposed and Q4 being the most exposed.Main outcome measures Self reported consumption of takeaway type food (g/day; pizza, burgers, fried foods, and chips) using food frequency questionnaires, measured body mass index, and cut-offs for body mass index as defined by the World Health Organization.Results In multiple linear regression models, exposure to takeaway food outlets was positively associated with consumption of takeaway food. Among domains at home, at work, and along commuting routes, associations were strongest in work environments (Q4 v Q1; beta coefficient=5.3 g/day, 95% confidence interval 1.6 to 8.7; P
