ABSTRACT
The validity of HbA1C and fasting plasma glucose(FPG)for screening of diabetes in community population was investigated.A total of 1 794 subjects from two sub-districts of Yangpu District,Shanghai,underwent a 75 goral glucose tolerance test(OGTT)and HbA1C determination.Based on 1999 World Health Organization criteria,there were 1 411 subjects with normal glucose tolerance(NGT),111 impaired fasting glucose(IFG),73 impaired glucose tolerance(IGT),33 IFG+IGT,and 166 diabetes.According to the receiver operating characteristic curve,the optimal cut-point of FPG for diagnosing diabetes was 6.15 mmol/L with sensitivity of 89.0%,specificity of 92.8%,and area under the curve of 0.959.The cut-point of HbA1C for diagnosing diabetes was 6.5% with a sensitivity and specificity of 71.1% and 80.2%.The area under the curve was 0.822.The screening model using FPG ≥6.1mmol/L and HbA1C≥6.5% had sensitivity of 66.9% and specificity of 97.0%.When the model was FPG ≥6.1 mmol/L or HbA1C ≥6.5%,the sensitivity and specificity was 96.3% and 76.7% respectively.The results suggest that both FPG and HbA1C have good value for screening diabetes in community,and FPG combined with HbA1C may further promote diagnostic efficacy.
