Diabetes and urbanization are major contributors to increased risk factors of cardiovascular diseases. Studying whether atherogenic dyslipidaemia increases with urbanization in type 2 diabetes mellitus is, therefore, important. The sample of the present study consisted of 400 subjects. They were categorized according to residential area and diabetes into four groups: urban diabetic group, urban non-diabetic control group (from a metropolitan city Delhi), rural non-diabetic diabetic group, and rural control group (from villages of Khanpur Kalan, Sonepat, Haryana). Differences in lipid levels and risk factors of emerging cardiovascular diseases between groups were evaluated with analysis of variance. Diabetic patients of both urban and rural areas had significantly higher total cholesterol (TC), triglycerides (TG), very low-density lipoproteins (VLDL), TC to high-density lipoprotein cholesterol (TC/HDL) ratio, TG to high‑density lipoprotein cholesterol (TG/HDL) ratio, and atherogenic index (AI) compared to respective controls (p<0.05). The HDL concentrations in urban diabetics were significantly lower (p<0.05) than in urban non-diabetic group and rural diabetic group. Comparison between urban and rural diabetic groups showed significantly higher atherogenic dyslipidaemia (AD) in the urban patient-group (p<0.05). We evaluated significant relationships of diabetes and urbanization with AD by multiple regression analysis. Receiver operating curve (ROC) analysis showed high area under curve (AUC) for TG/HDL in urban diabetic group (0.776, p<0.0001) and in rural diabetic group (0.692, p<0.0001). It is concluded that diabetes was associated with higher AD parameters. Urbanization in diabetes is also associated with elevated levels of AD, indicating higher risk in urban population. This study suggests that TG/HDL may be particularly useful as atherogenic risk predictor in newly-diagnosed type 2 diabetic patients.
