We explored differences in dietary behaviours, energy, and macronutrient intake among individuals who had regained or maintained weight loss 5 or more years after Roux-en-Y gastric bypass (RYGB). This study assessed 27 adults who underwent RYGB an average of 12.1 ± 3.7 years before this study was conducted. Dietary assessment was performed using 3-day food records. Daily energy intake (kcal), protein (g), carbohydrate (g), fat (g), and alcohol intake (g) were computed using the ESHA's Food Processor. Participants were classified by percent weight loss, maintainers (≥38 %), and regainers (≤30 %). Daily carbohydrate consumption was greater in regainers (222 ± 84.3 g) compared with maintainers (162 ± 67.5 g), (P < 0.05). Thirty-seven percent of participants were not consuming the recommended amount of protein and 26% reported never taking vitamin supplements after surgery. Alcohol consumption was higher among regainers (18.5 ± 30.9 g) compared with maintainers (2.6 ± 6.5 g), (P < 0.05). Finally, 74% of the participants reported no contact with a Registered Dietitian, whereas 78 % were in contact with a health care professional once a year post-surgery. Differences were seen in carbohydrate intake and alcohol consumption between weight maintainers and regainers. These data suggest dietitians need to play a more active role in the long-term care of this medically complex population.
我们探究了接受Roux-en-Y胃旁路术（RYGB）5年或更长时间后体重恢复或维持减重的个体在饮食行为、能量和常量营养素摄入方面的差异。本研究评估了27名成年人，他们在本研究开展前平均12.1±3.7年接受了RYGB手术。使用3天食物记录进行饮食评估。使用ESHA的食物处理器计算每日能量摄入量（千卡）、蛋白质（克）、碳水化合物（克）、脂肪（克）和酒精摄入量（克）。参与者按体重减轻百分比分类，即维持者（≥38%）和体重恢复者（≤30%）。与维持者（162±67.5克）相比，体重恢复者的每日碳水化合物消耗量更大（222±84.3克），（P<0.05）。37%的参与者未摄入推荐量的蛋白质，26%的参与者报告术后从未服用过维生素补充剂。与维持者（2.6±6.5克）相比，体重恢复者的酒精摄入量更高（18.5±30.9克），（P<0.05）。最后，74%的参与者报告未与注册营养师联系过，而78%的参与者术后每年与医疗保健专业人员联系一次。体重维持者和体重恢复者在碳水化合物摄入量和酒精消耗量方面存在差异。这些数据表明，营养师需要在这群医疗情况复杂的人群的长期护理中发挥更积极的作用。
