术后饮食失控（LOCE）与减肥手术后的体重结果和心理健康存在不利关联。然而，对于术后 LOCE 病程以及预测 LOCE 缓解、持续或发展的术前因素知之甚少。本研究旨在通过确定四组来描述手术后一年的 LOCE 过程：(1) 术后重新发生 LOCE、(2) 维持 LOCE（在手术前和术后认可）、(3) 缓解 LOCE（仅在手术前认可）和 (4) 从未认可 LOCE 的个体。探索性分析检查了基线人口统计学和心理社会因素的群体差异。共有 61 名成年减肥手术患者在术前以及术后 3、6 和 12 个月的随访中完成了问卷调查和生态瞬时评估。结果显示，13 例（21.3%）术前或术后从未认可 LOCE，12 例（19.7%）术后发生 LOCE，7 例（11.5%）术后有 LOCE 汇款证据，29 例（47.5%）术前和术后维持 LOCE。相对于那些从未认可 LOCE 的人，所有在手术前和/或术后证明 LOCE 的组都报告了更大的去抑制；那些患有 LOCE 的人报告说饮食计划较少；那些保持 LOCE 的人报告饱腹感敏感性较低，而享乐饥饿感较高。这些发现强调了术后 LOCE 的重要性以及长期随访研究的必要性。结果还表明，需要检查饱腹感敏感性和享乐饮食对 LOCE 维持的长期影响，以及膳食计划可以在多大程度上缓冲手术后重新发生 LOCE 的风险。
Postoperative loss of control eating (LOCE) has detrimental associations with weight outcomes and mental health following bariatric surgery. However, little is known regarding LOCE course following surgery and preoperative factors that predict remittance, continuance, or development of LOCE. The present study aimed to characterize LOCE course in the year following surgery by identifying four groups: individuals with (1) postoperative de novo LOCE, (2) maintained LOCE (endorsed at pre- and post-surgery), (3) remitted LOCE (endorsed only at pre-surgery), and (4) those who never endorsed LOCE. Exploratory analyses examined group differences in baseline demographic and psychosocial factors. A total of 61 adult bariatric surgery patients completed questionnaires and ecological momentary assessment at pre-surgery and 3-, 6-, and 12-month postoperative follow-ups. Results showed that 13 (21.3%) never endorsed LOCE prior to or after surgery, 12 (19.7%) developed LOCE after surgery, 7 (11.5%) evidenced remittance from LOCE after surgery, and 29 (47.5%) maintained LOCE prior to and after surgery. Relative to those who never endorsed LOCE, all groups who evidenced LOCE before and/or after surgery reported greater disinhibition; those who developed LOCE reported less planned eating; and those with maintained LOCE reported less satiety sensitivity and greater hedonic hunger. These findings highlight the importance of postoperative LOCE and need for longer-term follow-up studies. Results also suggest a need to examine the longer-term impact of satiety sensitivity and hedonic eating on LOCE maintenance, and the extent to which meal planning may buffer risk for de novo LOCE following surgery.
