[News-Medical.net] Vitamin D Deficiency Linked to Positive COVID-19 Test
The study by researchers at the University of Chicago looked at over 4,300 patients with COVID-19 of whom 499 had been tested for vitamin D levels in the previous year. Based on this, they were divided into likely deficient (25%), likely adequate (58%), and uncertain (16%).
Multiple variables were analyzed in this study. The researchers found that people with vitamin D deficiency at the last testing, and who did not receive higher doses of vitamin D (keeping them deficient in all probability), are much more likely to be infected with the virus than those with probably sufficient levels. The corresponding rates of infection were 22% vs. 12%.
the study even has this
Vitamin D deficiency is more common in black Americans due to the dense concentration of the ultraviolet-blocking chemical in the skin. Since this community has been disproportionately affected by COVID-19, in terms of both sickness and death, it would be wise to offer vitamin D testing to them. |
