摘 要:目的探索2010年美国糖尿病协会(ADA)推荐对糖尿病前期的诊断标准在我国青少年人群中的诊断价值。方法采用分层整群抽样法抽取东北地区中等发展城市辽阳市的初中和高中生933人(13-16岁),测定其糖化血红蛋白(HbA,。)和空腹血浆血糖(FPG)及各项生化指标。对符合2010年ADA推荐的糖尿病前期诊断标准的受试学生中同意进一步接受检查者(91人)进行标准口服葡萄糖耐量试验(OGTF),评估HbA1c标准和FPG标准各自与1999年世界卫生组织(WHO)对糖尿病前期的诊断标准(即OGTr标准)的一致程度。结果(1)初筛符合ADA2010年推荐的糖尿病前期诊断标准者213人,其中单独符合HbA1c诊断标准(HbA。。在5.7%-6.4%)或FPG诊断标准[FPG(5.6—6.9)mmol/L]者分别占72.3%(154/213)和23.O%(49/213),同时符合两个标准者仅占4.7%(10/213)。FPG识别HbA1c升高的ROC曲线下面积为O.56(P=0.023),而HbA1c诊断FGP升高的ROC曲线下面积无统计学意义(P=0.970)。(2)HbA1c诊断的糖尿病前期与OGTT标准的符合率仅为26.5%(18/68),而FPG诊断的糖尿病前期与OGTr标准的符合率达74.1%(20/27),两者比较差异有统计学意义(P〈0.01)。(3)与初筛的正常组相比,HbA1c升高(HbA1c〉5.7%)但被OGTF标准除外糖尿病前期者其糖尿病家族史比例、腰臀比、初筛FPG、血脂(三酰甘油、总胆固醇)、血尿酸水平均显著升高,而女性比例显著降低(均P〈0.05)。结论在中国青少年人群中识别糖尿病前期患者采用FPG标准优于HbA1c标准,但HbA1c水平增高也提示与青少年代谢异常相关。Objective To examine the diagnostic values of American Diabetes Association (ADA) -recommended (2010) hemoglobin A1c (HbA1c) as criterion in diagnosing pre -diabetes among adolescents. Methods A total of 933 junior and senior middle school students ( aged 13 ~ 16 yr; 46. 5% females) without known diabetes were randomly selected through cluster and stratified sampling from Liaoyang, a moderately developed northeast city. All participants completed questionnaires and underwent examination of vital signs, HbAlc, FPG, and some other biochemical indices. Pre -diabetes was diagnosed according to 2010 ADA criteria [ HbA1c5.7% ~ 6. 4% or FPG (5.6 ~ 6. 9) mmoL/L] . Pre - diabetes individuals willing to receive fur- ther examinations (n = 91 ) underwent OGTI'. The concordance between first screening results and OGTT results was evaluated for HbAlo and FPG, respectively. Results Of the 213 ( 22. 8% ) individuals diagnosed as pre - diabetes, roughly two thirds [72. 3% (154/213)] were identified by HbA1c alone and one third [23.0% (49/213)] were identified by FPG alone, with only 4. 7% ( 10/213 ) were identified by both tests simultaneously. The ROC curve for FPG to identify increased HbAlo had an ar- ea under the curve (AUC) of 0. 56 (P = 0. 023 ) , while AUC of HbAlo to identify increased FPG showed no statistical signifi- cance (P =0. 970) . In OGTT, among the 68 individuals with increased HbAIo in first screening, only 18 (26. 5% ) were con- firmed to be IGT or IFG; among the 27 individuals with increased FPG in first screening, 20 (74. 1% ) were diagnosed as IGTor IFG; coincidence rates of the HbA,c group and the FPG group were significantly different (P 〈 0.01 ) . Individuals with in- creased HbA1c (ADA 2010 criteria) and normal glucose tolerance (WHO 1999 criteria) showed higher levels of waist hip ratio, triglyceride, total cholesterol, uric acid and lower levels of female ratios than individuals with normal HbA1c and FPG ( all P 〈 0. 05�
