[目的]调查分析欠发达地区城镇居民糖尿病(DM)和糖调节受损(IGR)的流行病学特点。[方法]随机整群抽样调查甘肃白银市县20~74岁城镇常住居民3175名。[结果]DM患病率为5.23%,人口标化率为4.63%,新诊断率为62.05%;IGR患病率为6.46%,人口标化率为5.72%。单纯IFG者1.32%、单纯IGT者1.48%,IFG与IGT并存者3.65%,分别占IGR患者的20.49%、22.93%和56.59%。[结论]欠发达地区城镇居民糖尿病和糖调节受损的患病率低于我国发达地区,糖尿病发现率低于发达地区;无论仅以空腹血糖(FPG)或仅以餐后2h血糖(2hPG)作为血糖筛查指标,都会造成20%以上的IGR患者被漏诊。
[Objective] To investigate the epidemiological characteristics of diabetes mellitus (DM) and impaired glucose regulation (IGR) in urban areas in underdeveloped areas. [Method] A randomized cluster sampling survey was conducted in 3175 urban residents in cities and towns of Baiyin, Gansu, aged from 20 to 74 years. [Results] The prevalence rate of DM was 5.23%, the standardization rate of population was 4.63%, the new diagnosis rate was 62.05%. The prevalence of IGR was 6.46% and the standardization rate of population was 5.72%. Pure IFG 1.32%, simple IGT 1.48%, IFG and IGT coexisted 3.65%, respectively, accounting for 20.49%, 22.93% and 56.59% IGR patients. [Conclusion] The prevalence of diabetes and impaired glucose regulation in urban residents in underdeveloped areas was lower than that in developed areas in China. The prevalence of diabetes was lower in developed areas than in developed areas. Both fasting blood glucose (FPG) and postprandial 2h glucose (2hPG) As a blood glucose screening index, will cause more than 20% of IGR patients were missed.
