FOOD INTAKE EVALUATION DURING THE FIRST YEAR OF POSTOPERATIVE OF PATIENTS WITH TYPE 2 DIABETES MELLITUS OR GLYCEMIC ALTERATION SUBMITTED TO ROUX-EN-Y GASTRIC BYPASS

ABSTRACT Background : Obesity is one of the main causes of glycemic change. Failure of clinical obesity treatment may lead to an increase in bariatric surgery. Dietary guidance, in conjunction with disabsorptive and hormonal factors resulting from the anatomical and physiological changes provoked by the surgery, is associated with changes in food intake. Aim: To analyze food intake evolution during the first postoperative year of Roux-en-y gastric bypass in patients with type 2 diabetes mellitus or glycemic alteration. Methods : This was a longitudinal and retrospective observational study. For food intake evolution analysis, linear regression models with normal errors were adjusted for each of the nutrients. Results: At 12 months, all patients presented improvement in glycemic levels (p

摘要 背景：肥胖是引发血糖异常的主要原因之一。临床肥胖治疗失败可能会导致减重代谢手术（bariatric surgery）的实施量增加。饮食指导结合手术引发的解剖学与生理学改变所带来的吸收障碍及激素变化，与进食行为的改变密切相关。研究目的：分析接受Roux-en-Y胃旁路术（Roux-en-Y gastric bypass）的2型糖尿病（type 2 diabetes mellitus）或血糖异常患者术后第一年的进食量变化情况。研究方法：本研究为纵向回顾性观察研究。针对进食量变化分析，针对每一种营养素构建了带有正态误差项的线性回归模型。研究结果：术后12个月时，所有患者的血糖水平均得到改善（p
