中国糖尿病流行特点研究 糖尿病和糖耐量低减患病率调查

Study on the Epidemiological Characteristics of Diabetes Mellitus and IGT in China

为查明我国糖尿病流行情况 ,采用分层整群抽样方法 ,根据WHO诊断标准 ,对我国 11省(市 )居住 5年及 5年以上的社区人群进行了糖尿病患病率流行病学调查。研究对象包括 2 0至 74岁居民共 4 2 751人。结果显示 ,糖尿病 (DM )标化患病率为 3.2 1% ( 95%CI为 3.0 5%～ 3.37% ) ,糖耐量低减 (IGT)标化患病率为 4 .76% ( 95%CI为 4 .56%～ 4 .96% ) ,DM与IGT之比为 1∶1.5,患病率随年龄增大而上升 ,4 0岁以下人群DM患病率为 1.0 1%、IGT患病率为 2 .70 % ,50岁年龄组DM和IGT的患病率均达到 7%以上 ,60岁年龄组的DM和IGT患病率均超过 11%。

A community-based survey on diabetes mellitus(DM) and impaired glucose tolerance(IGT) was carried out in 11 provinces/autonomous regions/municipalities of China from July 1995 to June 1997,using stratified cluster sampling method and diagnostic criteria recommended by WHO. A total number of 42 751 persons aged 20-74 years having lived in the communities longer than 5 years,were selected as research subjects. Results showed that the prevalence rates of DM and IGT standardized by age were 3.21%(95%CI: 3.05%-3.37%) and 4.76%(95%CI:4.56%-4.96%) respectively; with a ratio of DM to IGT 1∶1.5. The prevalence rates of DM and IGT increased parallelly with the increase of age. Among the 20- 39 years old,the prevalence rates of DM and IGT were 1.01% and 2.70% respectively, while both of them exceeded 7% and 11% among people aged 50-59 years and above 60 years.
