Abstract

Background: Vitamin D deficiency is a common medical condition worldwide. In Iran, it has been reported that between 30-90% of people have vitamin D deficiency. However, its distribu-tion in different parts of the country and among different age and regional groups is unclear. There-fore, the aim of this study was to review the recent literature on vitamin D deficiency in Iran. Methods: The literature review was performed using Web of Science, PubMed-Medline, Scopus and Scientific Information Database (SID) with a cut-off date of November 2016 to identify articles on vitamin D status in Iran published in the last 10 years. Studies in English and Persian that reported vitamin D levels in male and female subjects of all age groups and in healthy populations were in-cluded. Results: From 325 studies that were initially retrieved, 82 articles met the inclusion criteria. A high prevalence of vitamin D deficiency was reported, and in some regions, this was reported as >90% and was found in all age groups and in all regions of Iran. Conclusion: This review highlights the very high prevalence of vitamin D deficiency in Iran. It will be important to recognize the importance of vitamin D deficiency as a major public health problem in Iran. © 2020 Bentham Science Publishers.
