摘　　要：目的探讨低血糖生成指数(GI)大米对2型糖尿病(T2DM)患者血糖的影响。方法选取2019年9-12月于四川大学华西医院门诊招募的T2DM患者21例为研究对象,通过自身前后对照,给予个体化糖尿病治疗膳食,前2 d进食普通大米套餐,后3 d进食低GI大米套餐,区别仅主食不同,比较患者进食不同套餐后的空腹血糖(FBG)及三餐2 h餐后血糖(2hPG)差异,分析进食两种套餐三餐后的2hPG变化量(Δ2hPG)与HbA1c相关性。并在进食结束后进行饮食指导,自行进食3个月后随访患者血糖情况。结果进食低GI大米套餐三餐后2hPG较试验前及进食普通大米套餐三餐后2hPG低(P<0.05);两种套餐的晚餐Δ2hPG与HbA1c呈正相关(P<0.05),相关系数为0.499,早餐、午餐Δ2hPG与HbA1c无相关性(P>0.05)。结论低GI大米可改善T2DM患者的餐后血糖,有助于糖尿病患者血糖管理。Objective To analysis the effect of low glycemic index(GI)rice on blood glucose in patients with type 2 diabetes mellitus(T2DM).Methods Twenty-one patients diagnosed with T2DM who were recruited in outpatient clinic from September to December 2019 were enrolled.According to the personalized diabetes treatment diet formulated by the dietitian by self-contrast method,they ate the ordinary rice diet for two days and the low-GI rice diet three days,whose rice were different only.Compared the differences in fasting blood glucose(FBG)and 2 h postprandial blood glucose(2hPG)between two diets,and analyzed the correlation between the change in 2hPG(Δ2hPG)after eating two diets and HbA1c.After the trial,the patients were given dietary guidance,and followed up the blood glucose level under self-controlled diet after 3 months.Results 2hPG of eating low-GI rice diet were lower than that of ordinary rice diet(P<0.05).Δ2hPG after dinner of two diets was positively correlated with HbA1c(P<0.05),the correlation coefficient was 0.499.There was no correlation betweenΔ2hPG after breakfast and after lunch of two diets and HbA1c(P>0.05).Conclusion Low-GI rice can help control postprandial blood glucose in patients with T2DM,and it is beneficial to blood glucose management of patients with T2DM.
