Emotional eating (EE) has been implicated as an important variable in bariatric surgery and is frequently assessed during preoperative evaluations. Little is known about the association between preoperative EE and postoperative outcomes. This study examined associations between preoperative EE, as measured by the Weight and Lifestyle Inventory, and 2-year postoperative percent weight loss.
Data collected during preoperative evaluations were analyzed retrospectively. A total of 685 patients completed intake data, with 357 patients (52 %) completing 2-year follow-up measures. The average time from the initial appointment to surgery is 6 months. Preoperative data was collected at approximately month 2 of this 6-month period. Follow-up data was collected during 2-year postoperative follow-up visits.
The average percent of weight lost was 22.93 (SD = 13.62). Analyses indicated that (1) EE was not associated with percent weight loss for the overall sample, (2) EE was not associated with percent weight loss for females, (3) EE in response to positive affect was associated with percent weight loss for males, and (4) the interaction between preoperative depressive symptoms and EE was not associated with percent weight loss for either sex.
While the WALI provides a fruitful means of gathering clinical information, results suggested no association between scores on Section H of the WALI and weight loss. The results suggest that EE may impact surgical outcomes differentially in men as compared to women. Future research should seek to replicate these findings and focus on gender differences related to surgical outcomes.
情绪性进食（EE）被认为是减肥手术中的一个重要变量，并且在术前评估中经常被评估。关于术前情绪性进食与术后结果之间的关联知之甚少。本研究调查了通过体重与生活方式量表测量的术前情绪性进食与术后两年体重减轻百分比之间的关联。
对术前评估期间收集的数据进行回顾性分析。共有685名患者完成了入组数据，其中357名患者（52%）完成了两年的随访测量。从初次预约到手术的平均时间为6个月。术前数据在这6个月期间的大约第2个月收集。随访数据在术后两年的随访就诊期间收集。
体重减轻的平均百分比为22.93（标准差 = 13.62）。分析表明：（1）对于总体样本，情绪性进食与体重减轻百分比无关；（2）对于女性，情绪性进食与体重减轻百分比无关；（3）男性对积极情绪的情绪性进食与体重减轻百分比有关；（4）术前抑郁症状与情绪性进食之间的相互作用与任何性别的体重减轻百分比均无关。
虽然体重与生活方式量表提供了一种有效的收集临床信息的方法，但结果表明该量表H部分的得分与体重减轻之间没有关联。结果表明，与女性相比，情绪性进食对男性手术结果的影响可能不同。未来的研究应试图重复这些发现，并关注与手术结果相关的性别差异。
