关于雇主赞助的经济激励措施对员工减肥的有效性，数据有限。为了测试两种财务激励设计在促进肥胖员工减肥方面的有效性。随机对照试验。在请求治疗分配时动态生成分配序列。参与者对分配是不盲目的；调查人员对分配是盲目的，直到收集到主要结果数据。费城儿童医院105名员工，体重指数在30到40公斤/平方米之间，24周每月称重(对照)(n=35)；个人奖励，达到或超过目标减肥目标，每人每月100美元(个人手臂)(n=35)；团体奖励，设计为每月500美元，在5人小组中任何参与者达到或超过他们的目标体重(团体手臂)(n=35)。24周后体重减轻(主要结果)；36周后体重减轻，体重减轻的行为介质的变化(次要结果)。团队激励参与者比单独的参与者减掉了更多的体重(组间减肥差异=平均9.7磅，95%可信区间4.4%至14.9%；P<；0.001)。在激励措施结束12周后，并对3组比较进行了调整，实验组参与者的体重减轻程度高于对照组参与者(组间体重减轻差异=平均6.5磅，95%可信区间为1.2%至11.7%；P=0.016)，但不超过单个参与者(差异=5.9磅，95%可信区间，0.8%至11.0%；P=0.024)。单一雇主，短期随访A基于群体的经济激励在促进肥胖员工在24周时减肥方面比个人激励和每月称重更有效。国家老龄研究所临床试验.gov标识：NCT01208350
There are limited data on the effectiveness of employer-sponsored financial incentives for employee weight loss. To test the effectiveness of two financial incentive designs for promoting weight loss among obese employees. Randomized controlled trial. Allocation sequence was generated dynamically at the time of request of treatment assignment. Participants were unblinded to assignment; investigators were blinded to assignment until collection of primary outcome data. Children’s Hospital of Philadelphia 105 employees with a body mass index between 30 and 40 kg/m2 24 weeks of monthly weigh-ins (control)(n=35); individual incentive, designed as $100 per person per month for meeting or exceeding target weight loss (individual arm)(n=35); group incentive, designed as $500 per month split between any participant within groups of 5 who met or exceeded their target weight loss (group arm)(n=35). Weight loss after 24 weeks (primary outcome); weight loss after 36 weeks, changes in behavioral mediators of weight loss (secondary outcomes). Group incentive participants lost more weight than individual arm participants (between-group difference in weight loss favoring group = mean 9.7 pounds, 95% CI 4.4 to 14.9; P < 0.001). Twelve weeks after incentives ended and adjusting for 3-group comparisons, group arm participants maintained greater weight loss than control arm participants (between-group difference in weight loss = mean 6.5 pounds, 95% CI 1.2 to 11.7; P = 0.016) but not more than individual arm participants (difference = 5.9 pounds, 95% CI, 0.8 to 11.0; P = 0.024). Single employer, short follow-up A group-based financial incentive was more effective than an individual incentive and monthly weigh-ins at promoting weight loss among obese employees at 24 weeks.
