While significant weight loss has been observed in the first two years following adjustable gastric banding (AGB), research on the long-term effectiveness of gastric restriction (e.g., 5 years) both on weight loss and eating behavior changes is scarce. The present study examined obese patients' changes in eating behavior preoperatively and 5 years after AGB and examined their associations with excess weight loss (EWL). Specifically, we focused on the association between the modification of three eating behavior profiles (i.e., restrained eating, emotional eating and external eating) and %EWL at 5 years. Among the 197 participants who underwent AGB, 136 completed the clinical assessments (weight, depression with the BDI, eating behavior with the DEBQ) before surgery, and after 5 years. Resultsshowed that the mean percentage of EWL was 47% after 5 years. Moreover, patients reported lower emotional eating and external eating after 5 years in comparison to the baseline, whereas there were no differences concerning restrained eating. Importantly, patients who presented higher %EWL at 5 years also reported a greater decrease in emotional eating between the two sessions than those with low %EWL. Our study underlines that eating behaviors are major variables involved in weight loss after gastric restriction. Results showed that emotional and external eating decreased significantly at 5 years whereas restrained eating behaviors did not vary between the pre- and postoperative stages. Moreover, the data suggest that a decrease in emotional eating accounts for the extent of EWL.
虽然在接受可调胃束带术（AGB）后的头两年观察到了显著的体重减轻，但关于胃限制（例如，5 年）对体重减轻和饮食行为改变的长期效果的研究却很少。本研究检查了肥胖患者在接受 AGB 术前和术后 5 年内饮食行为的变化，并检查了它们与超重减轻（EWL）的关系。具体来说，我们专注于三种饮食行为特征（即约束性饮食、情绪性饮食和外部性饮食）的改变与 5 年后的 EWL 之间的关系。在接受 AGB 的 197 名参与者中，有 136 名在手术前完成了临床评估（体重、BDI 评估的抑郁、DEBQ 评估的饮食行为），并在 5 年后完成了评估。结果显示，5 年后的 EWL 平均百分比为 47%。此外，与基线相比，患者在 5 年后报告的情绪性饮食和外部性饮食较低，而约束性饮食则没有差异。重要的是，5 年后 EWL 较高的患者在两次就诊之间的情绪性饮食减少量也高于 EWL 较低的患者。我们的研究强调，饮食行为是胃限制后体重减轻的主要变量。结果表明，情绪性和外部性饮食在 5 年内显著下降，而约束性饮食行为在术前和术后阶段没有变化。此外，数据表明，情绪性饮食的减少解释了 EWL 的程度。
