Relationship between Glycated Hemoglobin and Serum Lipid Profile in Type 2 Diabetes Mellitus – A Case-control Study

Abstract

Aims: The aim of the study is to find whether there is any relationship between glycated hemoglobin level and serum lipid profile in type 2 diabetes mellitus patients. Study Design: A total of 128 study participants were approached during a period 6 months of which 72 were confirmed cases of type-2 diabetes mellitus and remaining 56 were non- diabetic, and served as control subjects under the age group of 30-60 years. Methodology: Fasting blood samples were collected from all the subjects. Body Mass index (BMI) was calculated. Fasting plasma glucose, glycated hemoglobin (HbA1c) Total cholesterol (TC), triglyceride (TG) and High Density Lipoprotein (HDL) was measured using commercially available kits. Statistical analysis was performed by use o f SPSS version l6. Results: Plasma FBS level of diabetic group was significantly higher (p=0.001) than that of the non diabetic subjects as shown in table. TC, TG, LDL and VLDL were higher in diabetic group when compared to that of non-diabetic group, except for HDL which was lower in dian=betic group when compared to non-diabetic greoup. LDL was statistically significant between the non-diabetic and diabetic groups. HbA1c levels of both diabetic and non- diabetic groups showed a significant correlation with TG, HDL, LDL and VLDL (p<0.05) except for cholesterol. Conclusion: The findings of this study clearly indicate that HbA1c as a useful biomarker for long-term glycaemic control and also as a good predictor of lipid profile.
