Worksite Opportunities for Wellness

描述（由申请人提供）：超重和肥胖是当今美国最普遍的健康问题，影响超过64%的成年人，并对发病率和死亡率有显著影响：有大量证据表明，改善饮食习惯和增加体力活动可促进体重控制，降低疾病风险，并增强整体健康。在工作场所实施的健康促进方案有许多优点，包括有机会以节省时间和成本的方式接触到大量的人。 我们建议进行一项名为“健康的工作场所机会”（WOW）的工作场所干预，其中包括个人，团体和环境组成部分，旨在促进大学工作人员更健康的饮食和体育活动行为。具体目的是评估：（1）在2所大学工作场所提供我们的多组分WOW计划的可行性;（2）WOW在降低超重和肥胖的患病率或严重程度方面的疗效;（3）WOW在改善心血管疾病和2型糖尿病风险因素方面的疗效;以及（4）WOW对生活质量、缺勤和医疗保健利用的影响。将使用延迟治疗设计，其中研究中心A有1年干预和1年随访，研究中心B有1年对照期，然后是1年干预。将在基线和6、12、18和24个月时评估体重、体重指数、身体成分、腰围、血脂、血糖、健身、生活质量、缺勤和医疗保健利用。WOW干预措施包括一系列营养成分、身体活动成分和激励措施，包括每周一次的健康零食车、现场减肥观察者计划、现场锻炼计划、每月一次的健康午餐研讨会、自动售货机和自助餐厅中的健康食品、免费计步器、彩色步行路线地图、同事之间的团队比赛、个人健康报告和几次抽奖活动。

DESCRIPTION (provided by applicant): Overweight and obesity are the most prevalent health problems in the U.S. today, affecting more than 64% of adults, and contributing significantly to morbidity and mortality: There is substantial evidence that improving diet habits and increasing physical activity promote weight control, reduce disease risk, and enhance overall health. A health promotion program delivered at the worksite has numerous advantages, including the opportunity to reach a large number of people in a time-efficient and cost-effective manner. We propose to conduct a worksite intervention titled "Worksite Opportunities for Wellness" (WOW), which includes individual, group, and environmental components designed to promote healthier dietary and physical activity behaviors among university staff. The specific aims are to evaluate: (1) the feasibility of delivering our multi-component WOW program in 2 university worksites; (2) the efficacy of WOW on reducing the prevalence or severity of overweight and obesity; (3) the efficacy of WOW on improving risk factors for cardiovascular disease and type 2 diabetes; and (4) the impact of WOW on quality of life, absenteeism, and health care utilization. A delayed treatment design will be used, in which Site A has a 1-yr intervention with 1-yr follow-up, and Site B has a 1-yr control period followed by the 1-yr intervention. Assessments of weight, body mass index, body composition, waist circumference, lipids, glucose, fitness, quality of life, absenteeism, and health care utilization will be made at baseline and 6, 12, 18, and 24 months. The WOW intervention is comprised of a constellation of nutrition components, physical activity components, and incentives, including a weekly healthy snack cart, on-site Weight Watchers program, on-site exercise program, monthly healthy lunch seminars, healthier foods in vending machines and the cafeteria, free pedometers, colorful maps of walking routes, team competitions among coworkers, personal health reports, and several raffles.
