Self-reported poor dietary adherence following bariatric surgery is associated with less successful weight loss outcomes. Poor dietary adherence is a global construct lacking specificity regarding its underlying, clinically targetable, maladaptive eating behaviors.
Comprehensive online survey data were obtained from a sample of 274 adults who underwent Roux-en-Y surgery in the prior 1-12 years. Correlations between dietary adherence and six eating-related behaviors were calculated, with the frequency of each behavior reported on a 7-point scale. Linear regression modeling was applied.
All six maladaptive eating behaviors were highly correlated with dietary adherence (Pearson's r > 0.5): grazing (r = - 0.565), mindless eating (r = - 0.572), loss of control eating (r = - 0.517), eating "more than is best" after dinner (r = - 0.518), eating foods off of one's plan (r = - 0.557), and "when I eat something off-plan, I feel like I have blown it and I give up and eat more" (r = - 0.574). The estimated regression coefficients in the linear model was statistically significant, [F(5, 261) = 60.006, p < 0.001] and accounted for approximately 54% of the variance of global dietary adherence (R = 0.535, adjusted R = 0.526).
Six maladaptive eating behaviors accounted for a highly significant portion of post-Roux-en-Y patients' poor self- reported dietary adherence. Prospective studies are needed to investigate the relationship between targetable maladaptive eating behaviors and bariatric surgery outcomes.
减肥手术后自我报告的饮食依从性差与减肥效果欠佳有关。饮食依从性差是一个总体概念，在其潜在的、临床上可针对的适应不良饮食行为方面缺乏特异性。
从274名在过去1至12年接受过胃旁路手术的成年人样本中获取综合在线调查数据。计算饮食依从性与六种饮食相关行为之间的相关性，每种行为的频率以7分制报告。应用线性回归模型。
所有六种适应不良饮食行为均与饮食依从性高度相关（皮尔逊r>0.5）：随意吃零食（r=-0.565）、无意识进食（r=-0.572）、失控进食（r=-0.517）、晚餐后进食“过量”（r=-0.518）、食用计划外食物（r=-0.557）以及“当我吃了计划外的东西，我觉得自己搞砸了，然后就放弃并吃得更多”（r=-0.574）。线性模型中的估计回归系数具有统计学意义，[F(5, 261)=60.006，p<0.001]，约占总体饮食依从性方差的54%（R=0.535，调整后R=0.526）。
六种适应不良饮食行为在胃旁路术后患者自我报告的饮食依从性差中占很大比例。需要进行前瞻性研究来调查可针对的适应不良饮食行为与减肥手术结果之间的关系。
