There are increasing incidence of diabetes around the worldwide, and there are a lot of studies have been considering vitamin D’s role in the incidence, and improving glucose status in diabetes.


This study is done to evaluate the prevalence of vitamin D deficiency in diabetic patients in Sulaimani Diabetes and Endocrine Center.

Materials and Methods

This is a case-control study done on 100 diabetic patients compared to 100 persons in the general population in Sulaimani/Iraq. Their Vitamin D was estimated from June 1st, 2017 to December 1st, 2017.


Results: The mean age of the diabetic group was (49.68 yr. ± 8.64 SD), and the mean age of the non-diabetic group was (50.49 yr. ±6.78 SD). The mean vitamin D’s level in the diabetic group was (16.91 ng/dl ± 5.5 SD) and in a non-diabetic group was (16.21 ng/dl ±8.59) (P-values= 0.493). Among diabetic group vitamin D level is significantly higher in males with an average of 6.2 mg/dl in comparison to females, (P-Value = 0.024), among diabetic patients, Vitamin D level was deficient in (66%), insufficient in (19%) and was sufficient just in (15%), while in non-diabetic control group vitamin D level was deficient in (77%), insufficient in (20%) and sufficient just in (3%). The P-value for these differences is (0.0052).


The results of this study show the majority of our participants have suboptimal vitamin D level. Vitamin D level was lower in female patients in comparison to male patients.
