减肥手术是治疗严重肥胖症最有效的方法。然而，有证据表明，不适应的饮食行为，如暴饮暴食、吃草和进食时失去控制，可能会影响手术后的体重结果。目前的研究试图描述胃旁路手术(GBP)术后3-10年个体的体重结果、饮食模式和感知的健康相关生活质量，并评估饮食行为、体重结果和生活质量之间的关系。符合条件的参与者(N=497)完成了一项关于他们的饮食行为、与健康相关的生活质量和体重历史的互联网调查。参与者自我报告术后平均最大减重81%，术后3-10年(平均4.2年)平均减重70%。87%的人报告说体重回升了1到124磅(平均22.6磅)。暴食、暴食失控和放牧均与体重恢复显著相关(暴食r=0.24，P=0.006；失控r=0.36，P<；0.001；放牧r=0.39，P<；0.001)和较小的超重损失(暴食r=-0.21，P=0.013；失控r=-0.41，P<；0.001；放牧r=-0.27，P<；0.001)。较差的健康相关生活质量与暴饮暴食障碍(床)(t[463]=9.7，P<；0.001)和每周两次或两次以上的放牧(t[61]=9.0，P<；0.001)有关。这些发现表明，进食障碍和进食时失控是GBP后的重大问题，是体重减轻的风险因素。
Bariatric surgery is the most effective treatment for severe obesity. However, evidence suggests that maladaptive eating behaviors such as binge eating, grazing, and a loss of control when eating may impact postsurgical weight outcomes. The current study sought to characterize the weight outcomes, eating patterns, and perceived health-related quality of life of individuals 3-10 years following gastric bypass (GBP) surgery and to assess the relationships between eating behaviors, weight outcomes, and quality of life. Eligible participants (N = 497) completed an Internet survey of their eating behaviors, health-related quality of life, and weight history. Participants self-reported a mean maximum postsurgical loss of 81% of their excess weight and maintained a mean weight loss of 70% 3-10 years following surgery (mean 4.2 years). Eighty-seven percent reported weight regain ranging from 1 to 124 lb (mean 22.6 lb). Frequency of binge eating, a loss of control when eating, and grazing were all significantly correlated with greater weight regain (binge eating r = 0.24, P = 0.006; loss of control r = 0.36, P < 0.01; grazing r = 0.39, P < 0.001) and lesser excess weight loss (EWL) (binge eating r = -0.21, P = 0.013; loss of control r = -0.41, P < 0.001; grazing r = -0.27, P < 0.001). Poorer health-related quality of life was associated with binge eating disorder (BED) (t[463] = 9.7, P < 0.001) and grazing two or more times per week (t[361] = 9.0, P < 0.001). These findings suggest that eating disturbances and a loss of control when eating are significant following GBP and are risk factors for diminished weight outcomes.
