Abstract:
Objective To explore the optimal HbAlc diagnostic cutpoint in different glucose tolerance populations in the plateau region.Methods (1) 472 diabetes mellitus (DM) patients and highrisk groups accepting diabetes screening in the First Affiliated Hospital of Kunming Medical College (217 males and 255 females,≥20 years old,median age 54 years old) were collected,oral glucose tolerance test (OGTT) and HbAlc were tested.(2) the research subjects were divided into normal glucose adjustment group (NGT),Impaired fasting glucose group (IFG) and (or) Impaired glucose tolerance IGT group and diabetes mellitus (DM) group.The receiver-operating characteristic curve (ROC) was explored to determine the optimal HbA1c diagnostic cut point for IFG,IGT and DM status respectively.Results The average HbA1 c values of NGT,IFG and (or) IGT,DM groups were (6.06 ± 0.11) ％,(6.63 ± 0.11) ％,(8.70 ± 2.08)％ respectively,for IFG and IGT groups,the optimal HbA1c diagnostic cut points were 6.7％ and 6.6％,respectively; If use either FBG or 2 h PG to diagnose DM,the corresponding optimal HbA1 c diagnostic cut point was 7.1％ ; If use anyone of FBG or 2hPG to diagnose DM,the corresponding optimal HbA1c diagnostic cut point was 7.0％ ; If both FBG and 2hPG were used to diagnose DM,the corresponding optimal HbA1 c diagnostic cut point was 7.1％.Conclusion Preliminarily confirm the optimal HbA1c diagnostic cut point in different glucose tolerance populations in the plateau region of Kunming,and provide the evidence for further clinical application of HbA1c.
