广东省住院病人糖尿病调查

A survey of diabetes mellitus among inpatients in Guangdong province

目的 调查住院病人中糖尿病和糖调节异常（IGR）的流行情况和新诊断糖尿病病人的临床特点，以提高各科医务人员对糖尿病早期防治意识和水平。方法 2004年世界糖尿病日前一周，我们对广东省10所大学附属医院同期住院病人，先行空腹血糖（FPG）登记，其中FPG 5．6～6．9mmol／L之间而未诊断糖尿病的病人进行13服葡萄糖耐量试验（OGTT），糖代谢分类采用2003年美国糖尿病学会建议标准。结果 8753例住院病人中原已诊断糖尿病占8．3％，新诊断糖尿病占6．8％，新诊断IGR占4．9％。433例的住院病人进行了OGTT，其中27．9％可诊断为糖尿病，49．9％为IGR。在新诊断糖尿病中，伴发高血压194例（41．8％），伴发蛋白尿152例（43．2％），伴发血脂异常244例（67．6％）。结论 住院病人合并糖尿病和IGR的比例分别为15．1％和4．9％。在入院时未诊断为糖尿病而FPG于5．6～6．9mmol／L之间的病人，OGTT提示其中27．9％诊断为糖尿病。在新诊断的糖尿病病人中，已有较多的人伴发蛋白尿、血脂异常、高血压。

Objectives To investigate the prevalence of diabetes and impaired glucose regulation （IGR） among the inpatients and their clinical features. Methods A cross-sectional survey was conducted among the inpatients registered in ten university hospitals of Guangdong, China during the week before the Diabetes Day of 2004. The fasting plasma glucose （FPG） levels of first screen when the patients were hospitalized were recorded. Those with the FPG levels from 5.6 to 6. 9mmol/l. who had not been previously diagnosed as with diabetes （P-DM） underwent oral glucose tolerance test （OGTT）. The patients were classified into 5 groups according to the OGTT results： normal glucose tolerance （ NGT）, DM, impaired glucose tolerance （IGT）, impaired fasting glucose （IFG）, and IGT accompanied with IFG, the last 3 groups being called by a joint name of impaired glucose regulation （IGR）. Those with FPG≥7.0 mmol/L who had not been diagnosed as with DM previously were diagnosed as newly-diagnosed DM （New-DM）. Results Of the 8753 inpatients investigated 8.3% were with P-DM, 6. 8% were diagnosed as with New- DM, and 4. 9% were with IGR. OGTT was carried out in 433 inpatients. 27.9% of which were classified as with New-DM, and 49. 9% with IGR. In the New-DM patients, 41.8% were accompanied with hypertension, 43.2% with proteinuria, and 67.6% with dyslipidemia. Conclusion The prevalence rates of diabetes and IGR were 15. 1% and 4. 9% respectively among the inpatients investigated. The rate of diabetes was 27.9% among the patients underwent OGTT. Proteinuria, dyslipidemia, and hypertension were the concomitant disorders frequently found in New-DM.
