Hypovitaminosis D in patients with type 2 diabetes: risk factors and association with glycemic control and established microvascular complications.

Introduction: Several studies reported than vitamin D deficiency increases the risk of macrovascular and microvascular disease in patients with type 2 diabetes (T2DM). We investigated the plasma levels of 25OHD in adult patients T2DM, risk factors for 25OHD deficiency and the relationship between 25OHD, glycemic control and chronic complications of T2DM.

Methods: A cross-sectional study was carried out, in which 25OHD levels were evaluated in adult patients (over 18 years) with T2DM.
