目的 了解糖化血红蛋白(HbA1c)筛查糖尿病和糖代谢受损的敏感性并与空腹血糖(FBG)进行比较.方法 对400例无糖尿病病史的糖尿病高危人群同时检测FBG和HbA1c,据空腹血糖水平分为三组:A1组:FBG<6.1 mmol/L,计 336例,A2组:FBG 6.1-6.9 mmol/L,45例,A3组 FBG ≥7.0 mmol/L,19例.结果 (1)400例人群中,HbA1c≥6.0%,88例,异常率为22.0%;FBG≥6.1mmol/L,54例,异常率13.5.%,HbA1c的异常率高于FBG,P＜0.05.(2)A1组 HbA1c>≥6.0%,29例,占8.6%;A2组 HbA1c≥6.0%,41例,占91.1%;A3组 HbA1c≥6.0%,18例,占94.7%;(3)400例人群中,HbA1c≥6.0%或FBG≥6.1mmol/L,93例,异常率23.3%%.结论 HbA1c筛查糖尿病高危人群血糖异常的敏感性高于空腹血糖,两者联合检查有助发现更多糖代谢异常的患者.%Objective To investigate the clinical value of HbA1 c combined with fasting blood glucose(FBG)in screening diabetes and impaired glucose regulation, and compare the sensitivity between HbA1 c and FBG. Methods Fasting blood glucose and HbA1 c were measured simultaneously in 400 non-diabetic subjects with high risk for type 2 diabetes. All subjects were divided into three groups according to FBG,i. e. group A1 :FBG ＜6.1 mmol/L,n=336; group A2:FBG 6. 1-6.9 mmol/L,n =45; group A3:FBG≥7.0 mmol/L,n = 19. Results (1)Among the 400 subjects,the incidence rates of HbA1 c ≥ 6.0％ and FBG ≥ 6. l mmol/L were 22.0％ (88/400) and 13.5％ (54/400) ,respectively. The difference were significant with P ＜0.05. (2)The incidence rates of HbA1c more than and equal to 6.0％ were 8.6％ (29/336), 91.1％ (41/45) and 94. 7％ ( 18/19 ), respectively. ( 3 ) The rates of HbA1 c HbA1c ≥6.0％ or FBG≥6. lmmol/L was 23.3％ among the 400 subjects. Conclusion The sensitivity of HbA1c in screening abnormal glucose metabolism is higher than that of FBG,and combination test of HbA1c with FBG can help to find more people with abnormal glucose metabolism.
