摘 要:目的 探讨糖化血红蛋白(glycosylatedhemoglobin,HbAlc)在妊娠期糖尿病(gestationaldiabetesmellitus,GDM)病情程度评价、胰岛素使用及新生儿出生体重预测方面的指导价值。方法收集2005年1月1日至2011年8月31日于北京大学第一医院分娩的GDM孕妇中测定HbAlc者1074例的资料,75g口服葡萄糖耐量试验(oralglucosetolerancetest,OGTT)空腹、1和2h血糖诊断界值分别为5.1、10.0及8.5mmol/L,3点中任何1点血糖达到或者超过界值即诊断为GDM。采用Pearson相关分析探讨HbAlc与OGTT空腹、1和2h血糖水平之间的关系;采用受试者工作特性(receiveroperatingcharacteristic,ROC)曲线及Logistic回归分析HbAlc预测GDM孕妇需要使用胰岛素治疗及新生儿出生体重的效力。结果1074例GDM孕妇平均年龄为(31.8±4.O)岁,均于妊娠中、晚期行OGTT,平均孕周为(27.6±3.4)周,其中,空腹、1和2h平均血糖分别为(5.2±0.7)、(10.9±1.4)及(9.4±1.5)mmol/L。初次检测HbA1c的孕周为(31.8±4.3)周,HbA1c为(5.57士0.48)%。(1)HbAlc与OGTT血糖水平的关系:726例孕妇在OGTT后1个月内进行了HbA1C检测,HbA1C为(5.54±0.47)%。1点血糖异常者159例,HbA1C为(5.34±0.41)%,低于2点血糖异常者E293例,HbA1c为(5.47±0.41)%](t=3.025,P〈O.01);2点血糖异常者HbA1c低于3点血糖异常者[228例,HbA1C为(5.71±0.46)%](t=6.399,P〈O.01)。(2)HbA1c与需要胰岛素治疗的相关性:使用胰岛素治疗的299例孕妇HbAlc为(5.78±0.58)%,显著高于不需要胰岛素治疗者[775例,HbA1c为(5.42±0.37)%](t=9.431,P〈0.01)。HbA1c水平预测GDM需要胰岛素治疗的ROC曲线下面积为0.713,当HbA1C为5.67%时,预测GDM需要胰岛素治疗的敏感性与特异性分别为57.8%及75.5%。两因素Logistic回归分析示OR=6.847,95%Objective To evaluate the value of glycosylated hemoglobin (HbAlc) level in glucose monitoring, insulin therapy and neonatal birth weight prognosis in gestational diabetes mellitus (GDM) patients. Methods Data of 1074 women who were diagnosed as GDM and delivered at Peking University First Hospital between January 1, 2005 and August 31, 2011 were collected and retrospective analysis was conducted. The relationship of HbA1c level with plasma glucose level of oral glucose tolerance test (OGTT), insulin administration and neonatal birth weight were investigated with Pearson correlation analysis, Logistic regression analysis or receiver operating characteristic (ROC) curve. Results OGTT was done on 1074 women with (31.8± 4.0) years old during the second and third trimester and diagnosed GDM at (27.6 4-3.4) weeks of gestational age. Among them, glucose level of fasting and 1 and 2 hours after OGTT were (5.2±0.7), (10.9±1.4) and (9.4±1.5) mmol/L. The levels of HbAlc were (5.57±0.48)% at the fist time of HbAlc testing at (31.8±4.3) weeks of gestational age. (1)The average value of HbAlc in 726 women determined at one month after OGTT was (5. 54±0.47)%, and increased from (5. 34±0.41) % in women with one abnormal item in OGTT to (5.47±0.41)G and (5.71±0.46)% in women with two or three abnormal items inOGTT (t=3.025 and 6.399,all P〈0.01). (2) HbAlc level in women received insulin therapy was higher than those who did not F(5. 78±0.58) % vs (5. 42±0.37)%, t=9. 431, P〈0.01] . The sensitivity and specificity were 57.8G and 75.50//00 respectively in predicting insulin requirement in women with GDM at the cut-off value of 5.67%for HbAlc (Logistics analysis: OR= 6. 847,95%CI:4. 588-10. 218,P^0. 01). (3) Maternal HbAlc level at the third trimester was higher in large for gestational age(LGA) group than that in non-LGA group [(5. 754-0.52)% vs (5. 54± 0.42) G, t=6. 845 ,P〈0. 01].
