Although bariatric surgery is an effective treatment of morbid obesity, many patients fail to lose significant weight or regain weight over time. This study examined pre-surgical psychosocial predictors (stress, social support for healthy eating, emotion regulation, and sleep quality/quantity) of three-month post-surgical percent excess weight loss (EWL) in a population of adult bariatric surgery patients. Overall, findings suggest higher levels of stress (B = -.248, p =.017) and less social support for healthy eating (B =.311, p =.013) predict lower three-month post-surgery percent EWL. Emotion regulation, and sleep measures did not predict post-surgery percent EWL. Therefore, level of stress and social support should be assessed prior to bariatric surgery and considered important pre-surgical intervention targets.
尽管减重手术是治疗病态肥胖的有效方法，但许多患者在手术后无法显著减重或随着时间的推移体重又出现反弹。本研究考察了成年减重手术患者人群中，手术前的心理社会预测因素（压力、健康饮食的社会支持、情绪调节和睡眠质量/数量）对术后三个月多余体重减轻百分比（EWL）的影响。总体而言，研究结果表明，较高的压力水平（B=-.248，p=.017）和较少的健康饮食社会支持（B=.311，p=.013）预示着术后三个月的 EWL 百分比较低。情绪调节和睡眠指标与术后 EWL 百分比无关。因此，在进行减重手术前应评估压力水平和社会支持程度，并将其视为重要的术前干预目标。
