With no pharmacological agents successfully implemented to control the outbreak, the use of less invasive nonpharmacological agents, such as vitamin\u2009D, are increasingly being studied. This purpose of this article is to determine the current knowledge about the risk of COVID-19 development for populations at risk for vitamin\u2009D deficiency, including individuals living with overweight and obesity, those of older age, and racial or ethnic minorities. Despite the documented impact of vitamin\u2009D on viral disease prevention, many subgroups at risk for contracting COVID-19 are also known to have increased rates of vitamin\u2009D deficiency. Because vitamin\u2009D is most commonly obtained from sunlight, when interpreted alongside the stay-at-home orders, the importance of identifying safe approaches to obtain sufficient vitamin\u2009D is apparent. Furthermore, elucidating the cause-and-effect relationship between vitamin\u2009D and COVID-19, including optimal dosing for COVID-19 outcomes, is also warranted for immediate investigation.<\/jats:p>","DOI":"10.1093\/nutrit\/nuaa092","type":"journal-article","created":{"date-parts":[[2020,7,9]],"date-time":"2020-07-09T15:10:36Z","timestamp":1594307436000},"page":"227-234","source":"Crossref","is-referenced-by-count":22,"title":["The implications of vitamin D deficiency on COVID-19 for at-risk populations"],"prefix":"10.1093","volume":"79","author":[{"given":"Rosemary","family":"DeLuccia","sequence":"first","affiliation":[{"name":"Department of Nutrition Sciences, College of Nursing and Health Professions, Drexel University, Philadelphia, Pennsylvania, USA.
