Laparoscopic sleeve gastrectomy (LSG) incidence has increased worldwide. However, a proportion of patients achieve inadequate weight loss and some experience weight regain. Little is known of the influence of eating beliefs and behaviours in response to cravings on early weight loss trajectory. This study aimed to identify the post-surgery eating cravings that predicted patients not achieving excess weight loss outcome (EWL) at 6-8 months post-LSG.
A total of 106 (80.7% female) participants who underwent LSG from four sites completed the questionnaires at 4-6 weeks post-bariatric surgery and 6 months post-LSG. Achieving <40% EWL at 6-month follow-up was included as the outcome variable, and the nine subscales of the Food Cravings Questionnaire-Trait version (FCQ-T) were included as potential predictors of that change.
Logistic regression was used to examine the relationship between EWL and the nine subscales of the FCQ-T (intentions to eat, positive reinforcement, negative reinforcement, lack of control, preoccupation with food, feelings of hunger, negative affect, emotions experienced before or during food cravings or eating, and guilty feelings).
Participants lost an average 64% EWL (SD = 21% EWL) 6-8 months after LSG surgery. Results indicated the overall model was significant and, of the nine variables, the emotional food craving subscale (adjusted OR = 4.19, p = .018) predicted a failure to achieve EWL.
Emotional food cravings experienced 4-6 weeks following LSG may predict poor weight loss outcomes at 6 months. Statement of contribution What is already known on this subject? The prevalence of obesity has reached epidemic proportions worldwide. Bariatric surgery is currently the most viable and cost-effective treatment for obesity and shows sustainability. Laparoscopic sleeve gastrectomy (LSG) is now the most common procedure. Not all patients achieve excess weight loss outcome (EWL) following LSG. What does this study add? Emotional food cravings contribute to weight loss outcomes at 6 months' post-LSG surgery. Emotional food cravings may be a maladaptive coping mechanism that represents important area for early psychological intervention.
腹腔镜袖状胃切除术（LSG）的发病率在全球范围内有所增加。然而，一部分患者的减重效果并不理想，有些患者甚至出现体重反弹。对于术后因渴望而产生的饮食信念和行为对早期减重轨迹的影响，我们知之甚少。本研究旨在确定术后饮食渴望与 LSG 术后 6-8 个月不能达到超重减轻（EWL）的结果之间的关系。
共有 106 名（80.7%为女性）参与者在减重手术后 4-6 周和 LSG 术后 6 个月完成了问卷。将 6 个月随访时未达到<40%EWL 作为结果变量，并将食物渴望特质问卷（FCQ-T）的九个分量表作为该变化的潜在预测因素。
使用逻辑回归来检查 EWL 与 FCQ-T 的九个分量表（进食意向、正强化、负强化、缺乏控制、对食物的关注、饥饿感、负性情绪、在食物渴望或进食前后体验到的情绪、和内疚感）之间的关系。
LSG 手术后 6-8 个月，参与者平均减轻了 64%的 EWL（标准差为 21%EWL）。结果表明，整体模型具有统计学意义，在九个变量中，情绪性食物渴望分量表（调整后的 OR=4.19，p=0.018）预测了 EWL 的失败。
LSG 术后 4-6 周时经历的情绪性食物渴望可能预示着 6 个月时减重效果不佳。
