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.
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.
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).
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.
在垂直袖状胃切除术后，饮食行为在体重反弹中的作用仍不明确。本研究旨在探讨垂直袖状胃切除术对超重减轻（EWL）以及五个与饮食相关变量（食物成瘾、去抑制、饥饿易感性、饮食限制和体重关注）的影响，同时探究术前及术后八个月这些变量之间的关联。
从加拿大魁北克的一个医疗中心招募了76名接受垂直袖状胃切除术的参与者。测量指标包括体重指数（BMI）、饮食失调检查（体重关注）、耶鲁食物成瘾量表（食物成瘾）以及三因素饮食问卷（去抑制、饥饿易感性和饮食限制）。在术前（T0）和术后八个月（T8）之间进行t检验，并在T0与T8之间、T0内部以及T8内部检查相关性。
在T8时，平均超重减轻率为63.43%±13.14。T0与T8之间的比较显示，食物成瘾、去抑制和饥饿易感性显著降低（p = 0.001 - 0.005）。饮食限制和体重关注方面未观察到显著差异。T0时的BMI与T8时的超重减轻呈负相关（r = -0.45）。在T0内部，食物成瘾与饮食限制呈负相关（r = -0.42），而在T8内部则从负相关变为正相关（r = 0.35）。
本研究证实垂直袖状胃切除术对体重减轻有效，且与不良饮食行为的减少相关。术后，食物成瘾程度较高的个体表现出更多的饮食限制，这表明在那些对食物有强烈欲望的人群中需要进行限制。然而，即使在显著减重后，体重关注仍然很高，这表明仅靠减重可能不足以实现改变。术后关注整体健康和生活方式调整的医学随访将是至关重要的补充。
