Patients' height, weight (BMI calculated accordingly), waist circumference and serum vitamin D levels were measured. Chi-Square, Krystal-Wallis and Fishers exact tests were used, and the Bivariate Correlation test was used to determine the relationship between two variables.

The highest levels of vitamin D were found in patients with normal weight. Vitamin D deficiency was most common in obese patients. Serum vitamin D were significantly associated with obesity, but had no significant association with waist circumference. A study with a larger sample size in this area, is recommended.
