Loss-of-control (LOC) eating is associated with poor weight-loss outcomes following bariatric surgery. It is not clear whether eating patterns (e.g., total number of daily meals/snacks, eating after suppertime, eating when not hungry) and unhealthy weight control behaviors (e.g., smoking, using laxatives) are associated with or predictive of LOC eating.
To examine whether eating patterns and unhealthy weight-control behaviors are associated with LOC eating and, if so, whether they predict LOC eating in bariatric patients.
Multicenter study, United States.
This is a secondary analysis of the Longitudinal Assessment of Bariatric Surgery-2 study. Assessments were conducted before surgery and at 12, 24, 36, 48, 60, and 84 months after surgery. Logistic mixed models were used to examine the longitudinal associations between eating patterns, unhealthy weight-control behaviors, and LOC eating. Time-lag techniques were applied to examine whether the associated patterns and behaviors predict LOC eating.
The participants (n = 1477) were mostly women (80%), white (86.9%), and married (62.5%). At the time of surgery, the mean age was 45.4 ± 11.0 years and the mean body mass index was 47.8 ± 7.5 kg/m. The total number of daily meals/snacks, food intake after suppertime, eating when not hungry, eating when feeling full, and use of any unhealthy weight-control behaviors were positively associated with LOC eating (P < .05). Food intake after suppertime, eating when not hungry, and eating when feeling full predicted LOC eating (P < .05).
Meal patterns and unhealthy weight control behaviors may be important intervention targets for addressing LOC eating after bariatric surgery.
失控性进食与减肥手术后不佳的体重减轻结果相关。目前尚不清楚饮食模式（如每日进餐/零食的总数、晚餐后进食、不饿时进食）和不健康的体重控制行为（如吸烟、使用泻药）是否与失控性进食相关或可预测失控性进食。
研究饮食模式和不健康的体重控制行为是否与失控性进食相关，若相关，它们是否能预测减肥患者的失控性进食。
美国多中心研究。
这是对减肥手术纵向评估-2研究的二次分析。在手术前以及术后12、24、36、48、60和84个月进行评估。使用逻辑混合模型来研究饮食模式、不健康的体重控制行为和失控性进食之间的纵向关联。应用时间滞后技术来研究相关模式和行为是否能预测失控性进食。
参与者（n = 1477）大多为女性（80%）、白人（86.9%）且已婚（62.5%）。手术时，平均年龄为45.4±11.0岁，平均体重指数为47.8±7.5kg/m²。每日进餐/零食的总数、晚餐后食物摄入量、不饿时进食、饱腹时进食以及任何不健康体重控制行为的使用与失控性进食呈正相关（P < .05）。晚餐后食物摄入量、不饿时进食和饱腹时进食可预测失控性进食（P < .05）。
饮食模式和不健康的体重控制行为可能是解决减肥手术后失控性进食问题的重要干预目标。
