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.
减重手术是治疗严重肥胖症最有效的方法。然而，有证据表明，不良的进食行为，如暴食、乱吃零食和进食失控，可能会影响手术后的体重结果。本研究旨在描述胃旁路手术后 3-10 年个体的体重结果、进食模式和感知到的健康相关生活质量，并评估进食行为、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进食行为、健康相关生活质量和体重史的网络调查。参与者自我报告的最大手术后体重减轻率为其超重体重的 81%，并在手术后 3-10 年内（平均 4.2 年）保持 70%的平均体重减轻率。87%的人报告体重有不同程度的反弹，范围从 1 磅到 124 磅（平均 22.6 磅）。暴食、进食失控和乱吃零食的频率均与体重反弹幅度较大（暴食 r=0.24，P=0.006；进食失控 r=0.36，P<0.01；乱吃零食 r=0.39，P<0.001）和体重减轻幅度较小（暴食 r=-0.21，P=0.013；进食失控 r=-0.41，P<0.001；乱吃零食 r=-0.27，P<0.001）相关。健康相关生活质量较差与暴食障碍（BED）（t[463]=9.7，P<0.001）和每周乱吃零食两次或以上（t[361]=9.0，P<0.001）有关。这些发现表明，胃旁路手术后会出现进食障碍和进食失控，这是体重结果不佳的危险因素。
