Bariatric surgery is a life-changing treatment, but knowledge of its influence on changes in work ability is still limited. We hypothesized that self-reported work ability improves in response to surgery-induced weight loss and sociodemographical variables (e.g., age, sex, and marital status), and that psychosocial characteristics (e.g., depressive symptoms and dysfunctional eating) may have predictive value as to patients' work ability.
A total of 200 participants scheduled for bariatric surgery were recruited between September 2015 and June 2018. They completed several self-report measures at the preoperative examination (t1) and at 6- (t2) and 12 months (t3) after bariatric surgery. A repeated-measures analysis of variance was calculated to detect any changes in the work ability and body mass index (BMI) among the 3 time points. Further, a hierarchical multiple regression analysis was used to determine whether any demographical and psychosocial characteristics at (t1) would predict work ability at (t3).
Participants (82% of whom were women) were middle-aged and showed a BMI of nearly 46 at the preoperative medical examination. Excess weight loss at (t2) and at (t3) was 49 and 66%, respectively. Work ability increased toward a moderate level after weight-loss surgery. Work ability and dysfunctional eating at (t1) showed significant predictive value with respect to work ability at (t3).
The results suggest that weight-loss surgery has a positive impact on work ability, and indicate a predictive value for the extent of weight loss and dysfunctional eating behavior. Against our hypothesis and in contrast to former research, a predictive value for depressive symptoms and age was not revealed. Further research must show how interventions can support and maintain improvements in work ability after bariatric surgery, in order to reduce sick leave and unemployment in patients with preoperative morbid obesity.
减重手术是一种改变生活的治疗方法，但人们对其对工作能力变化的影响知之甚少。我们假设，自报告的工作能力会随着手术引起的体重减轻和社会人口学变量（例如年龄、性别和婚姻状况）而提高，并且心理社会特征（例如抑郁症状和饮食失调）可能对患者的工作能力具有预测价值。
2015 年 9 月至 2018 年 6 月期间，共招募了 200 名计划接受减重手术的参与者。他们在术前检查（t1）以及减重手术后 6 个月（t2）和 12 个月（t3）时完成了几项自我报告的测量。进行重复测量方差分析以检测 3 个时间点之间工作能力和体重指数（BMI）的任何变化。此外，使用分层多元回归分析来确定（t1）时的任何人口统计学和心理社会特征是否可以预测（t3）时的工作能力。
参与者（82%为女性）年龄适中，术前医学检查的 BMI 接近 46。（t2）和（t3）时的超重减轻量分别为 49%和 66%。减重手术后，工作能力逐渐提高到中等水平。（t1）时的工作能力和饮食失调具有显著的预测价值，可预测（t3）时的工作能力。
结果表明，减重手术对工作能力有积极影响，并表明体重减轻程度和饮食失调行为具有预测价值。与我们的假设相反，与以前的研究相比，抑郁症状和年龄没有显示出预测价值。进一步的研究必须表明如何干预可以支持和维持减重手术后工作能力的提高，以减少术前病态肥胖患者的病假和失业。
