Post-Surgical Predictors of Depression and Weight Regain after Bariatric Surgery

摘要： 最近的研究清楚地表明，相当大比例的减肥手术患者经历了 手术后体重大幅增加，并与抑郁症作斗争。了解相关机制 导致这些负面临床结果的因素具有相当大的科学和临床重要性。在 在目前的研究中，我们提出了一个预测模型，我们认为这会导致体重回升和抑郁。我们 我将检验这样一种观点，即在那一刻，压力和负面情绪预示着饮食失控，而这一切都结束了 时间、饮食失控预示着这些患者的体重回升和抑郁。我们还将调查 去抑制对这些关系的影响。此外，我们将利用当代生态 瞬时评估和动态评估技术，以测量这些变量并研究其 前瞻性纵向设计中体重恢复和抑郁的关系。最后，我们将纵向 检查减肥手术后体重恢复和抑郁，以澄清两者之间的时间关系 这些变量。

Abstract: Recent studies have clearly indicated that a significant proportion of bariatric surgery patients experience substantial weight regain and struggle with depression following their surgery. Understanding the mechanisms that contribute to these negative clinical outcomes is of considerable scientific and clinical importance. In the present study, we propose a model of predictors that we believe result in weight regain and depression. We will test the idea that in the moment, stress and negative affect predict loss of control eating, and that over time, loss of control eating predicts weight regain and depression in these patients. We will also investigate the influence of disinhibition on these relationships. Furthermore, we will use contemporary ecological momentary assessment and ambulatory assessment techniques to measure these variables and study their relationship to weight regain and depression in a prospective, longitudinal design. Finally, we will longitudinally examine weight regain and depression following bariatric surgery to clarify the temporal relationship between these variables.
