目的采用美国糖尿病学会2003年标准,比较空腹血糖(FPG)和2hPG(OGTT)判定糖耐量异常的能力。方法研究对象均在同一天早晨空腹抽血后立即进行OGTT,Kappa 一致性比较检测FPG和2hPG两种方法的诊断能力。结果 1197例患者中,共检出807例(67.4%)正常血糖者、267例(22.3%)糖尿病前期患者和123例(10.3%)糖尿病患者。与2hPG相比,FPG能显著提高糖尿病前期的检出率,但明显降低了糖尿病的检出率;与之相反,2hPG能显著提高糖尿病的检出率,但明显降低糖尿病前期的检出率。结论采用FPG联合OGTT 2hPG测定能提高糖尿病前期的检出率。
Objective To adopt the 2003 American Diabetes Association criteria to compare impaired fasting glucose (FPG) and 2hPG (OGTT) to determine the ability of impaired glucose tolerance. Methods The subjects were on the same day immediately after fasting blood OGTT, Kappa consistency comparison of two methods of detection of FPG and 2hPG diagnostic ability. RESULTS: Of the 1197 patients, 807 (67.4%) normal blood glucose, 267 (22.3%) pre-diabetic patients and 123 (10.3%) diabetic patients were detected. Compared with 2hPG, FPG can significantly improve the detection rate of pre-diabetes, but significantly reduce the detection rate of diabetes; on the contrary, 2hPG can significantly increase the detection rate of diabetes, but significantly reduce the detection rate of pre-diabetes. Conclusion FPG combined with OGTT 2hPG determination can improve the detection rate of pre-diabetes.
