摘要:

目的:探讨大理地区应用糖化血红蛋白(HbAlC)诊断2型糖尿病和空腹血糖调节受损(IFG)的可行性,并确定相应的诊
断切点。方法:2型糖尿病(T2DM)患者332例、空腹血糖调节受损(IFG)175例,行葡糖糖耐量试验(OGTT)及糖化血红蛋白
(HbAlC)检测,采用ROC曲线分析以确定诊断2型糖尿病对应HbAlC最佳切点。结果:IFG组和T2DM组的FBG、HbAlC平均水平
高于健康对照组,差异具有统计学意义(P<0.05)。HbAlC用于诊断2型糖尿病的最佳临界值为6.25%,敏感度为86.5%,特异度
95.2%,曲线下面积(AUC)为0.959(95%置信区间0.945-0.973)。结论:HbA1c用于评估IFG的最佳临界值为5.51%,HbA1c用于
诊断2型糖尿病的最佳临界值为6.25%,HbAlC可作为T2DM诊断标准之一。

Abstract:

Objective: To investigate the feasibility of hemoglobin A1C(HbA1C)diagnosing type 2 diabetes mellitus and Impaired
Fasting Glucose(IFG), and determine the diagnostic cut point. Methods: Oral Glucose Tolerance Test(OGTT)and HbA1C were
detected in patients with 332 cases of type 2 diabetes mellitus(T2DM) and 175 cases of Impaired Fasting Glucose. Receiver
Operating Characteristic Curve(ROC)was used to determine the optimal HbA1C diagnostic cutoff point for type 2 diabetes mellitus.
Results: The FBG and HbA1C levels of the IFG and T2DM group were higher than normal healthy control group with statistical
significance(P<0.05). According to ROC, the optimal cutoff point of HbA1C for the diagnosis of type 2 diabetes mellitus was 6.25%,
and its sensitivity was 86.5%, its specificity 95.2%, the AUC was 0.959(95% CI: 0.945-0.973). Conclusion: The optimal cutoff point
of HbA1C for the diagnosis of Impaired Fasting Glucose was 5.51%, and the optimal cutoff point of HbA1c for the diagnosis of type 2
diabetes mellitus was 6.25%. HbA1C is an available parameter in diagnosing T2DM.

Key words: diabetes mellitus, HbA1c, Impaired Fasting Glucose
