控制体重是预防多种肥胖相关健康状况的主要公共卫生焦点。虽然以诊所为基础的强化生活方式干预是成功的，但低社会经济地位（SES）人群，肥胖负担更高，很难达到;因此，工作场所提供了一个有用的设置，以针对低SES工人。本文介绍了一项研究的设计测试工作场所的干预，旨在低SES员工。该项目将与大型医疗保健系统和附属大学合作，测试一种创新的多层次干预（“为你工作”），该干预是根据现有的群体和个人干预模式进行调整的，旨在促进低收入工人的健康体重。个人层面的组成部分是一个互动式肥胖治疗方法（iOTA）计划，涉及行为风险评估，与健康教练合作设定目标，以及互动式短信持续支持和自我监测。这种移动健康干预措施嵌入在组级组件中，这是一个工作场所参与计划，涉及参与设计和实施干预措施以改变其工作场所环境的工人团队。这些嵌套式干预措施正在22个工作组（约1000名工人，约300名肥胖工人）的分组随机试验中进行测试。主要结局将是与对照组相比，2年随访时计划对体重的影响，次要结局将是对饮食和体力活动的影响;还将检查iOTA依从性、过程测量和工作环境/支持。这项实用的临床试验将测试可扩展的干预措施，这些干预措施可以转化为其他工作环境，以减少低SES工人的肥胖和相关健康风险。registrationClinicalTrials.gov
Weight-control is a major public health focus for preventing multiple obesity-related health conditions. While clinic-based intensive lifestyle interventions are successful, low-socioeconomic-status (SES) populations, which have a higher burden of obesity, are difficult to reach; thus, the workplace offers a useful setting to target low-SES workers. The current paper presents the design of a study testing a workplace intervention aimed at low-SES employees. Partnering with a large healthcare system and affiliated university, this project will test an innovative multi-level intervention (“Working for You”) adapted from existing group- and individual-level intervention models to promote healthy weight among low-wage workers. The individual-level component is an interactive obesity treatment approach (iOTA) program that involves assessment of behavior risks, collaborative goal-setting with a health coach, and interactive SMS text-messages for ongoing support and self-monitoring. This mHealth intervention is embedded in the group-level component, a workplace participatory program that involves worker teams engaged in the design and implementation of interventions to change their workplace environments. These nested interventions are being tested in a group-randomized trial among 22 work groups (~1000 total workers, ~300 workers with obesity). The primary outcome will be program effects on weight at 2-year follow-up, compared to control, and the secondary outcomes will be effects on diet and physical activity; iOTA adherence, process measures, and work environment/support will also be examined. This pragmatic clinical trial will test scalable interventions that can be translated to other work settings to reduce obesity and related health risks among low-SES workers.Trial registrationClinicalTrials.gov Identifier: NCT02934113
