The role of Vitamin D in various non–skeletal disorders including Diabetes Mellitus has been explored. The role of Vitamin D in peripheral utilization of glucose has been studied. This study evaluates the correlation between Vitamin D status and Glycated Haemoglobin in Type 2 Diabetes Mellitus. The present study was a retrospective case control study with 78 cases and 69 controls. Mann–Whitney Test was used to study difference in Vitamin D levels between cases and controls. Spearman correlation was used to study the correlation between Vitamin D levels and Glycated Haemoglobin in cases of Type 2 Diabetes Mellitus. The mean Vitamin D values in cases were 16.1 ng/ml and mean Vitamin D values in controls were 17.3 ng/ml. Though the mean values of Vitamin D in cases were lower than that of controls, the difference was not statistically significant (p=0.31). Vitamin D insufficiency was observed in both cases and controls. Spearman correlation showed there was no statistically significant correlation between Vitamin D levels and Glycated haemoglobin (p value 0.741) in cases of Type 2 Diabetes Mellitus. Hypovitaminosis D and its correlation with Glycaemic control could not be established.
