低血糖生成指数膳食对糖调节受损患者的影响

目的:探讨低血糖生成指数(low glycemic index,LGI)膳食干预对社区糖调节受损(IGR)患者血糖和血脂代谢的影响。方法:选取广州市人民街18个居委会,随机分为对照组和实验组,每组各9个居委会,每组随机选取IGR患者38例。在接受GI知识教育后,实验组采取LGI膳食干预8个月,观察患者的血糖、血脂的变化。结果:膳食干预后,实验组空腹血糖、餐后2 h血糖、糖基化血红蛋白、甘油三酯、总胆固醇、低密度脂蛋白和胰岛素抵抗水平均显著低于对照组,高密度脂蛋白胆固醇显著高于对照组。结论:在社区糖尿病防治工作中,采取低GI膳食可有效地控制IGR患者的血糖、血脂水平,降低胰岛素抵抗。

EFFECTS OF LOW GLYCEMIC INDEX DIET ON THE PATIENTS WITH IMPAIRED GLUCOSE REGULATION

Objective:To observe the effects of low glycemic index(GI) diet on the patients with impaired glucose regulation(IGR).Method:Eighteen communities were randomly divided into two groups,i.e.experiment and control groups.Thirty-eight patients with IGR were randomly selected in each group respectively.Low GI diet was instructed in experiment group.After eight months,the changes of blood glucose,blood lipid profile,insulin activity,etc were measured.Results: Compared with control group,fasting and postprandial blood glucose and glycosylated-hemoglobin,triglyceride,total cholesterol,low-density lipoprotein cholesterol and insulin resistance were decreased significantly and high-density lipoprotein cholesterol increased significantly after dietary intervention.Conclusion:Low GI diet is effective in controlling blood glucoses and blood lipids,decreasing insulin resistance of the patients with impaired glucose regulation.
