Invited Review
IntroduCtIonVitamin D deficiency (VDD) is a global problem, which is related to lack of sunlight exposure, with a contribution from reduced dietary intake. [1,2] VDD affects mainly the skeletal structure and function. In addition, there are a number of recognized nonskeletal effects that have wide ramifications. [3] Despite living in a sunny country all year round, paradoxically, hypovitaminosis D with clearly demonstrable low serum Vitamin D levels has been repeatedly recorded in the United Arab Emirates (UAE) and the surrounding Arabian Gulf countries. This problem has attracted increasing clinical and academic interests. However, the relevant publications are too widely scattered in different types of journals of different levels of access for the interested clinician and researcher to follow them and may be difficult to grasp them. Hence, in the present article, we aimed to present a narration of the international literature focusing on Vitamin D status and the clinical implications of its deficiency to make it available for practicing clinicians and researchers developing a new interest in the subject.
materIals and methodsThis is a narrative nonsystematic review of the literature on the epidemiological and clinical aspects of Vitamin D status in the UAE, a country which is invariably sunny on a daily basis all the year round. PubMed search was conducted Deficiency of Vitamin D is a global problem related to lack of sunlight exposure and reduced dietary intake. Vitamin D deficiency (VDD) affects mainly skeletal structure and function but has a number of recognized nonskeletal effects that have wide ramifications. It sounds ironic that low serum Vitamin D levels are widely documented in a sunny country like the United Arab Emirates (UAE). The study objective was to review the literature on VDD in the UAE. This is a narrative nonsystematic review of the literature on the epidemiological and clinical aspects of Vitamin D status in the UAE based on PubMed search using two search terms "Vitamin D" and "Emirates." We discuss the various themes that emerged as follows: epidemiology and disease burden of VDD in the UAE population in general and in specific groups (adults, children, females, and pregnant and nursing mothers); awareness of dietary intake, climate, genetics, and metabolic factors affecting serum Vitamin D levels; and the overview of current clinical management guidelines, interventional trials, and clinical practices. VDD is a widely documented health problem in the UAE population as a whole and in several special groups. This may have serious skeletal and nonskeletal health implications.
