OBJECTIVE
To test the ability of two levels of modest financial incentives to encourage weight loss among overweight employees.
METHODS
This study used a randomized design with measurements at baseline, 3, and 6 months and two levels of financial incentives ($7 and $14 per percentage point of weight lost). Payments were structured so that all participants had equal ability to obtain the incentives during the study period.
RESULTS
At 3 months, participants with no financial incentive lost 2 pounds, those in the $7 group lost approximately 3 pounds, and those in the $14 group lost 4.7 pounds. Between baseline and 6 months, when the financial gains were equalized, weight losses were similar across groups.
CONCLUSION
This study revealed that modest financial incentives can be effective in motivating overweight employees to lose weight.
目的
测试两种适度经济激励水平促使超重员工减重的能力。
方法
本研究采用随机设计，在基线、3个月和6个月时进行测量，并设置了两个经济激励水平（每减重一个百分点分别为7美元和14美元）。支付结构设计为让所有参与者在研究期间有同等获得激励的能力。
结果
在3个月时，没有经济激励的参与者减重2磅，7美元组的参与者减重约3磅，14美元组的参与者减重4.7磅。在基线和6个月之间，当经济收益均等化时，各小组的体重减轻情况相似。
结论
本研究表明适度的经济激励能有效促使超重员工减重。
