This review divides the world into the Food and Agriculture Organisation\u2019s (FAO) major regions: the Americas, Europe, Oceania, Africa and Asia. Emphasis was placed on published data on the prevalence of serum 25-hydroxyvitamin D (25(OH)D) &lt; 25\/30 and &lt;50 nmol\/L (reflecting vitamin D deficiency and inadequacy, respectively) as well as vitamin D intake, where possible from nationally representative surveys.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Collating data from the limited number of available representative surveys from individual countries might suggest a relatively low overall prevalence of vitamin D deficiency in South America, Oceania and North America, whereas there is more moderate prevalence in Europe and Asia, and possibly Africa. Overall, the prevalence of serum 25(OH)D &lt; 25\/30 and &lt;50 nmol\/L ranges from ~5 to 18% and 24 to 49%, respectively, depending on FAO world region. Usual intakes of vitamin D can also vary by FAO world region, but in general, with a few exceptions, there are very high levels of inadequacy of vitamin D intake.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>While the burden of vitamin D deficiency and inadequacy varies by world regions and not just by UVB availability, the global burden overall translates into enormous numbers of individuals at risk.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1530\/ec-21-0282","type":"journal-article","created":{"date-parts":[[2021,12,3]],"date-time":"2021-12-03T10:36:05Z","timestamp":1638527765000},"update-policy":"https:\/\/doi.org\/10.1530\/crossmarkpolicy-10","source":"Crossref","is-referenced-by-count":138,"title":["100 YEARS OF VITAMIN D: Global differences in vitamin D status and dietary intake: a review of the data"],"prefix":"10.1530","volume":"11","author":[{"given":"Kevin D","family":"Cashman","sequence":"first","affiliation":[{"name":"Cork Centre for Vitamin D and Nutrition Research, School of Food and Nutritional Sciences, University College Cork, Cork, Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"416","reference":[{"key":"bib1","series-title":"Dietary Reference Intakes for Calcium and Vitamin D","year":"2011","unstructured":"Institute of Medicine.
