Individual Lipids and Lipid Ratios in Type-2 Diabetic Patients: Association with Glycemic Control Status

The amount of glycosylated hemoglobin (HbA1c) reflects the long-term glycemic control of patients with diabetes. HbA1c also predicts the risk for the development of diabetic complications such as cardiovascular disease (CVD). Patients with type-2 diabetes and the characteristic of dyslipidemia are frequently found. Also, dyslipidemia plays as an independent risk factor for CVD. This study was aimed to evaluate the relationship between glycemic control status with serum individual lipid profiles and lipid ratios in patients with type-2 diabetes. This cross-sectional study consisted of 80 patients. Depending on the HbA1c level, the patients were divided into two groups, good glycemic control group (HbA1c < 7.0%, n = 15) and poor glycemic control group (HbA1c ≥ 7.0%, n = 65). The association of HbA1c with individual lipids (TC, TG, HDL-C, LDL-C, Non- HDL-C) and lipid ratios (TC/HDL-C, TG/HDL-C, LDL-C/HDL-C, monocyte/HDL-C) were analyzed. The value of individual lipids and lipid ratios did not correlate with HbA1c level (p-value ≥ 0.05). Parameters of individual lipids and lipid ratios were not independently associated with poor glycemic control, which was analyzed by logistic regression. ROC analysis found both LDL-C and LDL-C/HDL-C were not accurate to be used as a prognostic indicator of poor glycemic control in patients with type-2 diabetes (p = 0.155, p = 0.297, respectively). The present study found that there was no association between individual lipids and lipid ratios with glycemic control status.
