PDF Full Text


Many COVID-19 deaths among those enumerated in the context of the 2020 corona virus pandemic appear to be associated more often than not with obesity. At the same time, obesity has been linked to a deficiency in vitamin D, a factor that appears to hold some promise for advancing our ability to intervene in reducing COVID-19 severity. This mini-review reports on what the key literature is reporting in this regard, and offers some comments for clinicians and researchers. Drawn from PUBMED, data show that a positive impact on both obesity rates and COVID-19 morbidity and mortality rates may be attained by efforts to promote vitamin D sufficiency in vulnerable groups.
