25-hydroxy Vitamin D Levels and Relationships Between 25-hydroxy Vitamin D and Glycemic Status

Objective: It was found that vitamin D has effect on insulin secretion and insulin sensitivity as well as bone health. The aim of the study; 1. to determine the 25-hydroxy vitamin D (25-OH D) levels in elderly with type 2 diabetes. 2. to assess the relationships between 25-OH D levels and fasting blood glucose (FBG) and postprandial blood glucose (PBG) and HbA1c levels. Material and Methods: One houndred fifty five diabetic patients ≥65 years of age (mean age= 72.4±6.2 years (127 female, 28 male), were enrolled in the study. Demographic caracteristics, 25-OH D, biochemical tests were evaluated retrospectively. Results: Mean level of 25-OH D was found to be 37.9±5.1 ng/mL. 25-OH D levels were
