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 distribution in different parts of the country and among different age and regional groups is unclear. Therefore, 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 included. 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.

Background: Vitamin D has several roles, namely physiological function of calcium and bone metabolism, cell growth and differentiation, immune and cardiovascular function. Vitamin D deficiency can cause the risk of cancer. Head and neck cancer is one of the cancers that occur due to vitamin D deficiency in the body. This literature review was to asses and evaluate the impact and benefits of vitamin D supplementation for head and neck cancer.Discussion: A study found an association between vitamin D supplementation and a low risk of recurrence in conditions of high total vitamin D levels. Another study found a significant increase in quality of life (QOL). The primary mechanism of vitamin D action is mediated through binding of either 1,25(OH)2D3 (active form) or 25(OH)D (less active form) to the VDR, which is a member of the nuclear receptor superfamily of steroid and thyroid hormones with gene-regulatory and consequent anti-proliferative properties.Conclusions: Vitamin D supplementation provides a role in improving the condition of patients with head and neck cancer. Both in terms of suppressing recurrence and in terms of increasing quality of life

Abstract Objectives To assess existing evidence of the impact of vitamin D deficiency on reproductive success in infertile anovulatory females with polycystic ovary syndrome (PCOS) and evaluate the possible need for vitamin D supplementation. Methods A systematic literature review of published studies (2009–2019) on this topic was performed. One investigator independently reviewed primary research articles, extracted details, and determined the quality of each study. Results Of 64 peer-reviewed articles identified, 5 were reviewed, 5 were of plus/positive quality. Two studies assessed the prevalence of vitamin D deficiency in PCOS patients. One study assessed vitamin D administration effect on endometrial thickness, and two studies evaluated the effect of vitamin D status on ovulation and live birth rates after ovulation induction. Conclusions Vitamin D deficiency is prevalent in PCOS patients. Vitamin D status is an independent predictor of reproductive success in anovulatory patients with PCOS during ovulation induction. In such patients, vitamin D deficiency is associated with decreased ovulation and live birth rates, and vitamin D supplementation improves endometrial thickness. Based on the current data, further research is needed; meanwhile clinicians should monitor vitamin D status and recommend vitamin D supplementation to infertile anovulatory PCOS women with vitamin D deficiency.
