DESCRIPTION (provided by applicant): Obesity is at epidemic proportions and costs US employers an estimated $78.5 billion annually; yet national data reveal that less than 25% of employers are offering disease management programs to address obesity. Effective weight loss programs are needed that are easily adaptable to busy work environments, maintain employee privacy, and keep employees engaged over time (to help avoid weight re-gain). In collaboration with the North Carolina Community College System, NC Blue Cross Blue Shield, and the State Teachers and Employee Medical Plan, the proposed five-year study will test two promising worksite-based weight loss interventions (Web-based Weight Loss Program and Incentive Payments) among 936 overweight/obese employees in 12 community college settings. After formative work to adapt these interventions for community college campus employees, we will rigorously test the interventions using a group-randomized, 2x2 factorial design: WEB (yes or no) and INCENTIVE PAYMENT (yes or no) with 234 employees per treatment arm. The primary outcome (weight loss) will be measured at baseline, 6, 12, and 18 months. Most secondary outcomes (weight loss behaviors, moderate-vigorous physical activity; total calories, percent body fat, fruit/vegetable intake, absenteeism, productivity, medical expenditures, and quality of life) will be assessed at baseline, 12 and 18 months. Objective diet (24 hr recalls) and physical activity (Actigraph) data will be collected at baseline and 18 months as well. Process tracking data will measure fidelity, dose delivered/received and acceptability/satisfaction. Extensive cost- and cost-effectiveness analysis, including return on investment, will be undertaken. If proven effective, this strong partnership model combined with powerful economic data offer a unique opportunity for intervention institutionalization and dissemination throughout the community college campus system.

描述（由申请人提供）：肥胖处的流行比例，使美国雇主每年造成785亿美元的损失；然而，国家数据显示，只有不到25％的雇主提供疾病管理计划来解决肥胖。需要有效的减肥计划，这些计划易于适应繁忙的工作环境，保持员工隐私，并随着时间的推移使员工参与进来（以避免体重重新获得）。在北卡罗来纳州社区学院系统，NC Blue Cross Blue Shield以及州教师和员工医疗计划中，拟议的五年研究将测试936个超重/肥胖员工在12个社区大学设置中的两个有希望的基于工作现场的减肥干预措施（基于Web的减肥计划和激励付款）。在为社区大学校园员工改编这些干预措施以适应这些干预措施之后，我们将使用集体随机的2x2阶乘设计进行严格测试干预措施：Web（是或否）和激励付款（是或否），每个治疗部门234名员工。主要结果（减肥）将在基线，6、12和18个月时测量。大多数次要结局（减肥行为，中等剧烈的体育锻炼；总卡路里，体内脂肪百分比，水果/蔬菜摄入量，缺勤，生产力，医疗支出和生活质量）将在基线，12和18个月时进行评估。客观饮食（24小时召回）和体育活动（Actigraph）数据也将在基线和18个月内收集。流程跟踪数据将衡量保真度，剂量交付/接收以及可接受性/满意度。将进行广泛的成本和成本效益分析，包括投资回报率。如果被证明有效，这种强大的合作伙伴模式与强大的经济数据相结合，为整个社区大学校园系统的干预制度化和传播提供了独特的机会。
