Food addiction (FA) following bariatric surgery (BS) has received a burst of attention in recent years due to its important contribution to obesity. Therefore, this study was conducted to explore the prevalence of FA disorder and its predictors 2 years after laparoscopic sleeve gastrectomy (LSG) and assess its relationship with physical activity (PA), body composition, and weight outcomes.
Four hundred fifty individuals who had undergone LSG 2 years prior to the study were enrolled. FA was diagnosed using the Yale Food Addiction Scale (YFAS). The collected data included body composition (fat mass (FM), fat-free mass (FFM)), PA, and nutritional intakes.
Eighty-nine subjects (about 20%) met the criteria for FA disorder. FA patients had significantly lower PA (p = 0.04) and higher weight (p < 0.001), BMI (p < 0.001), FM, and FFM (p = 0.01) compared to those without FA. Regarding weight and body composition changes, the finding reveals that FA patients (vs. non-FA) had a significantly less excess weight loss (EWL%) (p < 0.001) and total weight loss (TWL%) (p = 0.05) as well as a higher FFM loss (kg) (p = 0.04) (linear regression analysis). A younger age (p trend = 0.01), higher BMI (p trend = 0.04), and more excess weight (p trend = 0.03) were related to higher odds of FA disorder at second year after LSG (logistic regression analysis).
The results showed that FA was highly prevalent 2 years after LSG. In addition, FA disorder was associated with negative long-term outcomes following LSG. Younger individuals with more excess weight and higher BMI at baseline are more vulnerable to FA.
近年来，由于肥胖症的重要贡献，肥胖症患者在接受减重手术后（BS）出现食物成瘾（FA）的现象引起了广泛关注。因此，本研究旨在探讨腹腔镜袖状胃切除术（LSG）后 2 年内 FA 障碍的患病率及其预测因素，并评估其与身体活动（PA）、身体成分和体重结果的关系。
450 名在研究前 2 年内接受 LSG 的个体参与了本研究。采用耶鲁食物成瘾量表（YFAS）诊断 FA。收集的数据包括身体成分（体脂肪量（FM）、去脂体重（FFM））、PA 和营养摄入量。
89 名受试者（约 20%）符合 FA 障碍标准。与无 FA 的患者相比，FA 患者的 PA 显著降低（p=0.04），体重（p<0.001）、BMI（p<0.001）、FM 和 FFM（p=0.01）更高。关于体重和身体成分的变化，研究结果表明，与非 FA 患者相比，FA 患者的超重体重减轻百分比（EWL%）（p<0.001）和总体重减轻百分比（TWL%）（p=0.05）明显较低，FFM 丢失量（kg）（p=0.04）（线性回归分析）较高。年龄较小（p 趋势=0.01）、BMI 较高（p 趋势=0.04）和超重较多（p 趋势=0.03）与 LSG 后第二年 FA 障碍的发生几率较高相关（logistic 回归分析）。
研究结果表明，LSG 后 2 年内 FA 的发病率很高。此外，FA 障碍与 LSG 后负面的长期结果有关。在基线时体重超重更多、BMI 更高的年轻个体更容易发生 FA。
