Aim: To find out prevalence of Vitamin D deficiency and associated factors in T2DM patients. Methodology: Cross–sectional observational analysis conducted in 300 T2DM patients. Data collection tools included semi–structured questionnaire and fasting blood samples from subjects. SPSS version 25 was used for data analysis. Results: Prevalence of Vitamin D deficiency in T2DM was 84.6%. Statistically significant association between serum cholesterol and lipid profile with Vitamin D deficiency was found. Female gender and inadequate sunlight exposure were independent predictors of Vitamin D deficiency. Conclusion: High prevalence of Vitamin D deficiency was observed inT2DM patients. T2DM patients should be encouraged to get more sunlight exposure and health professionals should be more vigilant for Vitamin D deficiency detection among female diabetics.
