Insulin-induced hyperglycemia is the hallmark of diabetes mellitus (DM), including various metabolic disorders. Diabetic people are more likely to develop dyslipidemia, hypertension, and obesity. Type 2 diabetes (T2DM), the most common illness, is generally asymptomatic in its early stages and can go misdiagnosed for years. Diabetes screening may be beneficial in some cases since early identification and treatment can lessen the burden of diabetes and its consequences. This study aimed to find the relationship between Glycated hemoglobin (HbA1c) and lipid profile components in T2DM patients. This descriptive-analytical and cross-sectional study was performed on the control group and T2DM patients in Medical City in Baghdad between March and June 2021. A total of 90 patients with T2DM and 45 healthy control were included in this study. In the control group, healthy volunteer individuals participated. For all subjects, HbA1c, fasting blood sugar/FBS, and lipid profile (Total Cholesterol/TC, Triglyceride/TG, High-density Lipoprotein/HDL, Low-density Lipoprotein/LDL, and Very Low-density Lipoprotein/VLDL) were assessed. Among T2DM patients 62.22% (n= 56) were male and 37.78% (n= 34) were female. Mean ± SD levels of HbA1c, TC, TG, LDL, VLDL, HDL, and FBS were 7.33±0.56 % (168.21±9.23, 146.10±9.64, 137.23±8.32, 41.05±5.86, 43.85±6.17, and 208.81±52.1) mg/dl respectively in the T2DM group. In the control group, the Mean ± SD results of the same parameters were 4.91±0.27%, (171.20±3.57, 116.60±8.25, 105.05±2.11, 41.83±4.92, 44.04±5.54, 96.20±7.8) mg/dl respectively. Results demonstrated statistically significant differences between T2DM patients and control groups in HbA1c (p equal to 0.0025), TG (p equal to 0.015), LDL (p=0.0029), and FBS (p=0.02). Pearson correlation analysis of HbA1c with other variables showed a significant positive correlation with serum TC, TG, LDL, and FBS (r=0.573, P<0.01; r=0.655, P <0.001; r=0.498, P<0.05; r=0.691, P<0.001; respectively). While the data showed a negative connection between HbA1c and HDL (r= - 0.562, P<0.01) The findings of this study reveal that diabetic people do not have a satisfactory HbA1c level. Furthermore, HbA1c shows a significant correlation with TC, TG, LDL, and VLDL, whereas it has a significant negative correlation with HDL. The study showed that HbA1c might be useful for predicting dyslipidemia in T2DM patients. Keywords: T2DM, Lipid profile, HbA1c.
