目的 探讨低血糖指数膳食对肾移植术后早期糖代谢异常患者干预效应。方法 分析2009-01至2011-02 100例肾移植术后早期患者糖代谢异常发生率，将糖代谢异常患者随机分为2组，每组27例，对照组自由膳食，干预组低血糖指数（glycemic index, GI)膳食，营养干预30 d，观察干预前后空腹血糖（fasting blood glucose，FPG）和餐后2 h血糖（2 h plasma glucose，2 h PG）的变化情况。结果 肾移植患者术后糖代谢异常发生率为54%，发生时间为术后15~180 d，前3个月发生率为44%。干预30 d后，干预组FPG和2 h PG恢复正常，与干预前比较差异有统计学意义（ P＜ 0.01），与对照组比较差异有统计学意义（ P ＜0.01）。结论 低GI膳食可以积极控制肾移植术后早期患者糖代谢异常。

Objective To investigate the effect of nutrition intervention based on low glycemic index (GI) foods on blood glucose in patients soon after renal transplantion. Methods 100 renal transplantion patients were enrolled, whose incidence of glycometabolism disorder was analyzed. Patients with glycometabolism disorder were randomly divided into two equal groups. One group was given low glycemic index foods while the other was given free foods as control. The duration of treatment for both groups was 30 days. Changes in fasting blood glucose and 2 h plasma glucose in patients were observed. Results The incidence of glycometabolism disorder was 54%，and the disorder occurred 15 days to 180 days after renal transplantion. After low glycemic index food intervention, fasting blood glucose and 2 h plasma glucose in the treatment group decreased significantly ( P ＜0.01), much unlike control group ( P ＜0.01). Conclusions Nutrition intervention based on low GI foods helps alleviate glycometabolism disorder soon after renal transplantion．
