ABSTRACT

The most important effect of vitamin D is on calcium homeostasis and bone health. 25 hydroxy vitamin D (25-OH D) level should be measured to evaluate Vitamin D levels. The aim of this study was to determine whether vitamin D deficiency in patients admitted to our hospital and to establish the difference between 25-OH Vitamin D levels according to gender and age groups. The 25-OH vitamin D levels of a general adult population admitted to our hospital between 01.12.2010-22.08.2011 were investigated retrospectively through the hospital information system. Participants who had chronic illnesses were excluded from the study. Subjects were classified according to age groups (n=513). When comparing the serum levels of 25-OH D, there was no statistically significant difference among the groups [18-39 years, 40-69 years and 70 years and older (p>0.05)] .Also there was no statistically significant difference between groups in terms of gender (p>0.05). Mean 25-OH vitamin D levels of patients admitted to our hospital were found below 30 ng / ml. We determined that the prevalence of vitamin D deficiency (cut off value:20 ng/ml ) was 51.8% and that of vitamin D insufficiency was 20.7% in the population investigated. In many studies of vitamin D deficiency in adults, the prevalence was higher, especially in the Middle East and Asian countries. Vitamin D insufficiency was found to be very common in the population investigated from Ankara. According to this definition, widespread vitamin D insufficiency has been identified in this population. Because of the potential association of limited exposure to sunlight in Ankara and dietary factors we believe that dietary support and vitamin D supplementation would be appropriate.
