Abstract
Vitamin D deficiency is prevalent throughout the world. Some previous studies have shown that vitamin D deficiency accompanies type 2 diabetes but other researches have not confirmed that relationship. Evaluation of vitamin D deficiency in the patients with type 2 diabetes in comparison with the control group is the purpose of this study. This cross-sectional study was conducted on some patients with type 2 diabetes in Zahedan, southeast of Iran, in autumn and winter 2015. One hundred newly diagnosed type 2 diabetes patients were studied for their vitamin D serum level. Out of the general population, one hundred people having normal fasting plasma glucose were selected as the control group. The control group members were matched with the case group members based on sex, age ( one year), and body mass index ( 1). Vitamin D serum level was measured by enzyme immunoassay method immunodiagnostic system [IDS (LTD), UK]. The results were compared using statistical t-test. The average of vitamin D serum level in the case group was 19.13 15.84 ng/ml and 22.50 15.66 ng/ml in the control group. No statistically significant difference was observed between the averages of vitamin D serum levels in the case and control groups (p=0.13). Vitamin D serum levels in patients with diabetes and control group were not significantly different which could be due to the high prevalence of vitamin D deficiency in the general population.
