Abstract: Objective  To investigate the distribution of HbA1c and GSP in the Dai people of Yunnan  of different genders and ages. Methods  The levels of glycosylated hemoglobin (HbA1c), hemoglobin (hemoglobin, Hb), FPGcose (fasting blood glucose, FPG), glycosylated serum protein (GSP) and albumin (albumin, ALB) were detected, analysed and compared in 860 cases of Dai people for the difference and the change trend of each index groups of different genders and  ages (4150 years, 5160 years, 6170 years, >70 years old ). Results  There was no statistical significance  in levels of HbA1c, GSP and ALB between male and female (P>0.05), but the difference  in Hb and FPG between two genders was significant(P<0.05). All the indexes in male decreased with aging, while those of the female kept increasing until 60 years old, then the indexes began to fall. The pearson correlation test showed that there was correlation  in male and female  between HbA1c and FPG,  also ALB and GSP, and there was correlation  in female between Hb and HbA1c. Conclusion  On the premise of standardized determination, there is no gender difference in HbA1c and GSP levels among Dai people. However, their levels may vary in gender, and age,  those of males decreased with age, but females increased until they reached the turning  point60 years old.
