“…Vitamin D deficiency was long considered rare in Africa, but a systematic analysis of African countries revealed that severe vitamin D deficiency is present in 18% of all African subjects, with clusters having a high prevalence of deficiency widely dispersed based upon cultural/ behavioral practices. (18)(19)(20)(21)(22)(23)(24)(25)(26) 25OHD is the "best" marker of vitamin D status…”

The Third International Conference on Controversies in Vitamin D was held in Gubbio, Italy, September 10–13, 2019. The conference was held as a follow‐up to previous meetings held in 2017 and 2018 to address topics of controversy in vitamin D research. The specific topics were selected by the steering committee of the conference and based upon areas that remain controversial from the preceding conferences. Other topics were selected anew that reflect specific topics that have surfaced since the last international conference. Consensus was achieved after formal presentations and open discussions among experts. As will be detailed in this article, consensus was achieved with regard to the following: the importance and prevalence of nutritional rickets, amounts of vitamin D that are typically generated by sun exposure, worldwide prevalence of vitamin D deficiency, the importance of circulating concentrations of 25OHD as the best index of vitamin D stores, definitions and thresholds of vitamin D deficiency, and efficacy of vitamin D analogues in the treatment of psoriasis. Areas of uncertainly and controversy include the following: daily doses of vitamin D needed to maintain a normal level of 25OHD in the general population, recommendations for supplementation in patients with metabolic bone diseases, cutaneous production of vitamin D by UVB exposure, hepatic regulation of 25OHD metabolites, definition of vitamin D excess, vitamin D deficiency in acute illness, vitamin D requirements during reproduction, potential for a broad spectrum of cellular and organ activities under the influence of the vitamin D receptor, and potential links between vitamin D and major human diseases. With specific regard to the latter area, the proceedings of the conference led to recommendations for areas in need of further investigation through appropriately designed intervention trials. © 2020 The Authors.

“…Hypovitaminosis D has become pandemic and is now seen in every country in the world. It has been estimated that more than one billion people worldwide are either vitamin D deficient or insufficient [1]. Older people are more likely to have lower serum 25(OH)D concentrations [2], partly due to reduced ability to synthesize vitamins with increasing age [3].…”

“…Alarming levels of vitamin D deficiency among Egyptian females across all age groups have been demonstrated, prevalence of hypovitaminosis D is approximately 77.2% among healthy geriatric population [1]. There is evident relationship between vitamin D adequacy and various human disease including skeletal and extra skeletal manifestations.…”
