OBJECTIVE
To evaluate if self-efficacy (SE) and financial incentives (FI) mediate the effect of health behavior on weight loss in a group of overweight and obese nursing-home employees participating in a 16-week weight-loss intervention with 12-week follow-up.
METHODS
Ninety nine overweight/obese (body mass index [BMI] > 25) employees from four nursing-homes participated, with a mean age of 46.98 years and BMI of 35.33. Nursing-homes were randomized to receiving an incentive-based intervention (n = 51) and no incentive (n = 48). Participants' health behaviors and eating and exercise self-efficacy (Ex-SE) were assessed at week 1, 16, and 28 using a self-reported questionnaire. Mediation and moderated mediation analysis assessed relationships among these variables.
RESULTS
Eating self-efficacy (Eat-SE) and Ex-SE were significant mediators between health behaviors and weight loss (P < 0.05). Incentives significantly moderated the effects of self-efficacy (P = 0.00) on weight loss.
CONCLUSIONS
Self-efficacy and FI may affect weight loss and play a role in weight-loss interventions.
目的
评估自我效能感（SE）和经济激励（FI）是否介导了健康行为对一组参与为期16周减肥干预并进行12周随访的超重和肥胖养老院员工体重减轻的影响。
方法
来自四家养老院的99名超重/肥胖（体重指数[BMI]＞25）员工参与了研究，平均年龄为46.98岁，BMI为35.33。养老院被随机分为接受基于激励的干预组（n = 51）和无激励组（n = 48）。在第1周、16周和28周使用自我报告问卷评估参与者的健康行为以及饮食和运动自我效能感（Ex-SE）。中介和调节中介分析评估了这些变量之间的关系。
结果
饮食自我效能感（Eat-SE）和Ex-SE是健康行为与体重减轻之间的显著中介因素（P＜0.05）。激励显著调节了自我效能感（P = 0.00）对体重减轻的影响。
结论
自我效能感和FI可能影响体重减轻，并在减肥干预中发挥作用。
