Online published on 21 November, 2019. Abstract Background Studies show that vitamin D affects insulin sensitivity and insulin secretion, and vitamin D deficiency may also contribute to impaired glucose tolerance. 1, 2 Objectives The purpose of this study was to examine the association between serum 25 (OH)D and glycosylated haemoglobin (HbA1c) levels in patients with type 2 diabetes mellitus of Bengaluru city. Materials and Method A total of 50 type 2 diabetics were included in the study with a mean age of 55.78 (SD: 13.77) years of both gender previously diagnosed regardless of their sociodemographic characteristics and were invited for the assessment of vitamin D and HbA1c levels in Infilife healthcare private limited of Bengaluru city. Results Mean (SD) Hba1c and vitamin D levels were 7.17% (2.451) & 19.43 (16.094) ng/ml respectively. There was no statistically significant correlation between Hba1c and vitamin D levels with a correlation coefficient (r) of-0.109[p = 0.05]. Conclusion In the present study, there was no correlation between vitamin D levels and glycaemic control in patients with type 2 diabetes mellitus of Bengaluru city. Since there are conflicting results in the literature, further investigations may be more beneficial to highlight the relationship between glycaemic control and vitamin D.
