Abstract

Introduction: Vitamin D deficiency (VDD) causes same diseases such as osteoporosis, osteomalacia, and fractures, and also it is shown that Vitamin D deficiency could lead to some cardiovascular disease, diabetes and many types of cancer. Therefore, this study aimed to determine the frequency of vitamin D deficiency among referring to laboratories in Eyvan city during 2015 and 2016. Methods: A cross-sectional study was conducted in 2014 and 2015 on patients who were referred to the laboratories at Eyvan city. Serum levels of 25OHD were determined using a ELISA assay. The data were analyzed SPSS 17 software using descriptive and analytical tests. Results: Out of 2 919 participants, 2053 patients were women. The average age was 36.25±17.1 (range 1-92) yrs. The overall prevalence of vitamin D deficiency in the patients admitted to the medical laboratories was estimated that approximately 62%. The prevalence severe and moderate vitamin D deficiency was calculated 10.4 and 51.5, respectively. The prevalence of vitamin D deficiency among the ages 1-6, 7-18, 19-60 and over 60 years was estimated 45%, 59%, 64% and 58%, respectively. The mean vitamin D concentration was 36.25±18.79 ng/ml. The relationship between deficiency of vitamin D with age and gender was statistically significant (P=000). Conclusion: Vitamin D deficiency prevalence is high, so the intervention plan seems essential to avoid complications of vitamin D deficiency such as medication treatment and establishing nationally-mandated food fortification programs to enhance the intake of vitamin D.
