Abstract：
OBJECTIVE: Following vertical sleeve gastrectomy (VSG), the role of eating behaviors in weight regain remains unclear. This study aimed to examine the effects of VSG on excess weight loss (EWL) and five eating-related variables (food addiction, disinhibition, susceptibility to hunger, dietary restraint, and weight concern) while exploring their associations before and eight months post-surgery.
METHODS: A sample of 76 participants who underwent VSG was recruited from a healthcare center in Quebec, Canada. Measurements included body mass index (BMI), the Eating Disorder Examination (weight concern), the Yale Food Addiction Scale (food addiction), and the Three-Factor Eating Questionnaire (disinhibition, susceptibility to hunger, and dietary restraint). T-tests were conducted between pre-surgery (T0) and eight-month post-surgery (T8), and correlations were examined between T0 and T8, within T0, and within T8.
RESULTS: The mean EWL was 63.43% ± 13.14 at T8. Comparisons between T0 and T8 showed a significant decrease in food addiction, disinhibition, and susceptibility to hunger (p = 0.001-0.005). No significant differences were observed for dietary restraint and weight concerns. BMI at T0 was negatively correlated with EWL at T8 (r = -0.45). Within T0, a negative correlation was observed between food addiction and dietary restraint (r = -0.42), which changed from negative to positive within T8 (r = 0.35).
CONCLUSIONS: This study confirmed that VSG is effective for weight loss and associated with a reduction in maladaptive eating behaviors. Postsurgery, individuals with greater food addiction exhibited more dietary restraint, suggesting a need for restraint among those experiencing a strong drive toward food. However, weight concerns remained high even after significant weight loss, indicating that weight loss alone may not be sufficient for change. A postsurgery medical follow-up focusing on overall well-being and lifestyle adaptation would be a crucial complement.

摘要：
目标：垂直袖状胃切除术（VSG）后，饮食行为在体重恢复中的作用尚不清楚。这项研究旨在检查VSG对过度体重减轻（EWL）和五个饮食相关变量（食物成瘾，去抑制,对饥饿的易感性,饮食限制，和体重问题），同时在手术前和术后八个月探索它们的关联。
方法：从魁北克一家医疗中心招募了76名接受VSG的参与者，加拿大。测量包括体重指数（BMI），饮食失调检查（体重问题），耶鲁食物成瘾量表（食物成瘾），和三因素饮食问卷(去抑制，对饥饿的易感性,和饮食限制)。在手术前（T0）和手术后八个月（T8）之间进行T检验，并检查了T0和T8之间、T0内和T8内的相关性。
结果：T8时平均EWL为63.43%±13.14。T0和T8之间的比较显示食物成瘾的显着减少，去抑制,和饥饿易感性（p=0.001-0.005）。在饮食限制和体重方面没有观察到显着差异。T0时的BMI与T8时的EWL呈负相关(r=-0.45)。在T0内，观察到食物成瘾和饮食限制之间呈负相关（r=-0.42），在T8内由负变为正(r=0.35)。
结论：这项研究证实，VSG对减肥有效，并且与不良饮食行为的减少有关。手术后,食物成瘾程度较高的个体表现出更多的饮食限制，这表明需要在那些对食物有强烈渴望的人中保持克制。然而,体重问题仍然很高，即使在体重显著减轻后，表明仅靠减肥可能不足以改变。手术后的医疗随访侧重于整体福祉和生活方式的适应将是一个重要的补充。
