Abstract :
An inverse relationship has been shown between vitamin D deficiency and type 2 diabetes mellitus (DM). In this cross-sectional study in Tehran, Islamic Republic of Iran, a country with a high prevalence of vitamin D deficiency, we determined the prevalence of vitamin D deficiency among 90 type 2 DM patients and 90 healthy subjects. Based on serum levels of 25-hydroxyvitamin D, the rates of deficiency ( 50 nmol/L) and insufficiency (50–75 nmol/L) were 59.0% and 27.0% respectively in patients with type 2 DM, and 47.0% and 24.0% respectively in healthy subjects. Using the national cut-offs for vitamin D deficiency, 64.0% women with DM and 47.4% of healthy women were suffering from different degrees of vitamin D deficiency. The prevalence of vitamin D deficiency in men with type 2 DM and healthy men were 42.7% and 22.2% respectively. None of the differences between the 2 groups was statistically significant.
