目的 探讨各种不同的糖代谢异常 (糖调节受损和糖尿病 )在中国人群中的分布和特点。方法 研究对象为 1994年全国糖尿病防治协作组资料库中具有完整口服糖耐量试验 (OGTT)资料的 15 6 37例中国成人 (≥ 2 5岁 )。参考 1999年WHO糖尿病诊断标准将研究对象分为 7组 :正常糖耐量 [NGT ,空腹血糖 (FPG) <6 1mmol/L及OGTT2小时血糖 (PG 2h) <7 8mmol/L]、单纯空腹血糖受损 (i IFG ,6 1≤FPG <7 0mmol/L及PG 2h <7 8mmol/L)、单纯糖耐量异常 (i IGT ,FPG<6 1mmol/L及 7 8≤PG 2h <11 1mmol/L)、同时FPG及PG 2h异常 (IFG/IGT ,6 1≤FPG <7 0mmol/L及 7 8≤PG 2h <11 1mmol/L)、单纯空腹高血糖的糖尿病 (IFH ,FPG≥ 7 0mmol/L及PG 2h <11 1mmol/L)、单纯餐后高血糖的糖尿病 (IPH ,FPG <7 0mmol/L及PG 2h≥ 11 1mmol/L)、同时空腹及餐后高血糖的糖尿病 (IFH/IPH ,PG 2h≥ 11 1mmol/L及FPG≥ 7 0mmol/L)。计算以上各种糖代谢异常在本组人群发生频率并比较其临床特点。结果 (1)NGT、i IFG、i IGT、IFG/IGT、IFH、IPH和IFH/IPH的频率分别为 5 0 8%、8 8%、12 3%、6 1%、6 4 %、5 2 %和 10 4 %。 (2 )i IGT、IFG/IGT、IPH和IFH/IPH的频率有随年龄而增加的趋势 ,但i IFG和IFH频率分别在 2 5～ 34岁和 5 5
Objective To investigate the distribution and characteristics of different kinds of abnormal glucose metabolism (impaired glucose regulation and diabetes) in Chinese population. METHODS: Subjects were 15 6 37 Chinese adults (≥25 years old) with complete oral glucose tolerance test (OGTT) data from the 1994 National Collaborating Group on Diabetes Prevention and Control Data Bank. According to the WHO diagnostic criteria of WHO in 1999, the subjects were divided into 7 groups: normal glucose tolerance [NGT, fasting blood glucose (FPG) <61mmol / L, and OGTT2 hourly blood glucose (PG2h) (I IFG, 6 1 ≦ FPG <70 mmol / L and PG 2h <7 8 mmol / L), simple impaired glucose tolerance (i IGT, FPG 6 1 mmol / L and 7 8 ≦ PG 2 h <11 1 mmol / L) (IFG / IGT, 6 1≤FPG <70 mmol / L, and 7 8≤PG 2h <11 1 mmol / L), simple fasting hyperglycemia (IFH, FPG≥70 mmol / L and PG 2h <11 1mmol / L), simple postprandial hyperglycemia (IPH, FPG <70mmol / L and PG 2h≥11 1mmol / L) and fasting and postprandial hyperglycemia (IFH / IPH, PG 2h≥11 1mmol / L and FPG≥70mmol / L). Calculate the above various metabolic abnormalities in the frequency of this group of people and compare their clinical features. Results (1) The frequencies of NGT, i IFG, i IGT, IFG / IGT, IFH, IPH and IFH / IPH were 58.0%, 81.8%, 123.3%, 61.1%, 62.4% % And 104%. (2) The frequencies of i IGT, IFG / IGT, IPH and IFH / IPH tended to increase with age but i IFG and IFH frequencies were between 25 and 34
