Background: Glycosylated hemoglobin (HbA1c), fasting plasma glucose (FPG) and 2 hours (2-hr) after breakfast (ABF) plasma glucose, are often used to monitor and manage glycemia in stable diabetic patients. Data regarding the relationship and relative contribution of FPG and 2-hr ABF plasma glucose to HbA1c level in Type 2 diabetes mellitus (T2DM) are insufficient. Objective: To examine the correlation of FPG, and 2-hr ABF with HbA1c in known patients having T2DM; and to find out which one of FPG and ABF is the dominant contributor to overall glycemia in monitoring diabetes. Study Design and Methods: The study was carried on 664 known T2DM patients under treatment and routine follow-up at a tertiary care hospital in Bangladesh. FPG & 2-hr ABF plasma glucose concentrations were measured by hexokinase method. HbA1c was measured by high performance liquid chromatography based hemoglobin assay system. The Pearson correlation coefficient was used to investigate the relationship of FPG and ABF with HbA1c and their significance. Results: Both FPG and ABF levels were correlated with HbA1c but higher correlation was seen between FPG and HbA1c. The correlation coefficients between FPG and HbA1c and between ABF and HbA1c were 0.722 and 0.664 respectively. Both the correlations were found statistically significant (p<0.001). Conclusion: In patients with T2DM, FPG and ABF both were significantly correlated with HbA1c; and in our study we found that overall correlation of HbA1c with FPG was higher than ABF plasma glucose level.
