Objective: Among different micronutrient deficiencies, vitamin D deficiency (VDD) is considered pandemic nowadays. Therefore, present study aims to investigate the study of Vitamin D status in population who referred to the laboratories of Ilam city in 2014-2015.
Materials and Methods: This cross-sectional population-based survey was conducted among the patients who referred to five public and private laboratories of Ilam from July 2014 to July 2015. The samples were selected by a random procedure. 25-hydroxyvitamin D [25OHD] were determined by enzyme-linked immunosorbent assay (ELISA) method. Sufficient vitamin D was defined as serum 25OHD ≥ 30 ng/ml. Cut-off points for serum levels of 25OHD were defined as sufficient ( ≥ 30 ng/ml), insufficient (10-30 ng/mL) and severe deficiency (<10 ng/mL). Data were analyzed using SPSS Ver. 17 by descriptive statistics and analytical (Chi-square test).
Results: In total, 7,725 subjects (5,273 females and 2,452 males) with mean age 34.96±18.10 year were investigated. The prevalence of VDD was estimated to be 65.8%. Its prevalence was 67.3% among females, and 62.8% among the males. The prevalence of insufficient and severe VDD was estimated to be 53.7% and 12.1%, respectively. The highest prevalence of VDD was estimated for ages 18-60 years (68.3%). The mean 25OHD concentration was 27.02±18.04 ng/ml and this concentration for male and female was 28.39±16.48 and 26.41±18.60, respectively.The relationship between VDD and age and sex was statistically significant (P<0.001).
Conclusion: The results suggested that VDD is very prevalent in this region. Accordingly, it is necessary to take certain intervention measures such as medication and vitamin D-enriched nutrition to decrease VDD.
