Relationship between hemoglobin A1c and blood glucose throughout the day in well-glycemic-controlled medical nutrition therapy alone type 2 diabetic patients / 中国医学科学杂志(英文版)

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the relationship between glycosylated hemoglobin A1c (HbA1c) and blood glucose levels of eight different points throughout the day in well-glycemic-controlled medical nutrition therapy (MNT) alone type 2 diabetic patients.</p><p><b>METHODS</b>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 HbA1c and capillary blood glucose value was evaluated by Pearson's correlation method.</p><p><b>RESULTS</b>The r-values between HbA1c and capillary blood glucose of 300, 600, and bedtime (2200-2300) 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).</p><p><b>CONCLUSION</b>Fasting blood glucose and postabsorptive blood glucose have better correlations with HbA1c compared with other points in this group of well-glycemic-controlled MNT alone type 2 diabetic patients.</p>
