背景最近针对肥胖患者提出了每日蛋白质摄入量建议。我们的目的是评估这些建议的实现，和蛋白质摄入量（PI）对脂肪的影响，无质量（FFM）和蛋白质状态的变化后，减肥surgery.Methods我们检查了101例连续进行腹腔镜Roux-in-Y胃石膏（LGBP）或腹腔镜袖状胃切除术（LSG）。基于3天的食物记录，在术后4、8和12个月定量食物和补充剂的PI。PI和身体组成（生物电阻抗），血浆白蛋白和前白蛋白之间的关联进行了评估，在所有的研究时间points.Results PI < 60克/天，分别在45%，35%和37%的队列手术后4个月，8个月，12个月（相对于基线p < 0.001）。尽管我们普遍建议补充蛋白质，但在4、8和12个月时，只有63.4%、50.5%和33.7%的参与者服用了补充剂。然而，蛋白质补充剂可有效帮助患者实现每日蛋白质摄入量目标。在线性回归分析中，男性性别和体重减轻，但不PI，与FFM的损失显着相关（p < 0.001）。PI和血浆白蛋白或前白蛋白之间没有显着的相关性被发现。结论我们的研究强调了蛋白质补充的价值，为实现推荐的每日蛋白质摄入量的肥胖患者。然而，我们的数据并不能帮助定义一个PI的目标，在确定FFM和蛋白质状态的变化后LGBP或LSG的关键。
Background Daily protein intake recommendations have recently been proposed for the bariatric patient. We aimed to evaluate the accomplishment of these recommendations, and the influence of protein intake (PI) on fat free mass (FFM) and protein status changes following bariatric surgery.Methods We examined 101 consecutive patients undergoing laparoscopic Roux-in-Y gastric gypass (LGBP) or laparoscopic sleeve gastrectomy (LSG). Based on 3-day food records, PI from food and supplements were quantified at 4, 8, and 12 months after surgery. The association between PI and body composition (bioelectrical impedance), plasma albumin and pre-albumin was evaluated at all study time points.Results A PI < 60 g/day was present respectively in 45%, 35%, and 37% of the cohort at 4, 8, and 12 months after surgery (p < 0.001 relative to baseline). Despite our universal recommendation of protein supplementation, supplements were taken only by 63.4, 50.5, and 33.7% of the participants at 4, 8, and 12 months. However, protein supplementation was effective in helping patients to achieve the daily protein intake goal. In linear regression analysis, male gender and weight loss, but not PI, were significantly associated with loss of FFM (p < 0.001). No significant correlation between PI and plasma albumin or pre-albumin was found.Conclusions Our study underscores the value of protein supplementation for the achievement of the recommended daily protein intake in the bariatric patient. However, our data does not help to define a PI goal as critical in determining the FFM and protein status changes following LGBP or LSG.
