摘要
Objective To investigate the relationship between glycosylated hemoglobin A1 c （HbA1 c） and blood glucose levels of eight different points throughout the day in well-glycemic-controlled medical nutrition therapy （MNT） alone type 2 diabetic pafients. Methods Data were collected as＂ capillary blood glucose value of eight different sample points among sixteen observing days in thirty MNT alone type 2 diabetic patients. The correlation between HbAI c and capillary blood glucose value was evaluated by Pearson＇s correlation method. Results The r-values between HbA1c and capillary blood glucose of 3：00, 6：00, and bedtime （22：00-23：00） were 0. 81,0. 79, and 0. 78, respectively（P 〈0. 001 ）. The best correlation was found between the mean value of 8- point blood glucose value throughout the day and HbA1c （ r=0. 84, P 〈0. 001 ）. Conclustion Fasting blood glucose and postabsorptive blood glucose have better correlations with HbAlc compared with other points in this group of well-glycemic-controlled MNT alone type 2 diabetic patients.
