For several months, scientific studies have confirmed a lbeneficial link between vitamin D and Covid-19. A collective of doctors and several learned societies have also signed a column in La Revue du practitioner calling “to supplement the entire French population with vitamin D” in a preventive manner in order to help curb infection by the new coronavirus .
A new study supports this track. Indeed, patients with vitamin D deficiency are much more likely to test positive for COVID-19, according to a study published in the April issue of Nutrition.
Joseph Katz, DMD, of the College of Dentistry at the University of Florida at Gainesville, and colleagues examined the association between vitamin D deficiency and COVID-19 in a cross-sectional study of large cohorts of patients. Thus, the researchers found that compared to patients without deficiency, those who had vitamin D deficiency were 4.6 times more likely to be positive for COVID-19. After adjustment for gender and malabsorption, the association decreased slightly.
Moreover, after further adjustment with several factors (such as ethnicity, periodontal disease status, diabetes and obesity) the association decreased significantly but remained robust. After adjusting for age groups, patients with vitamin D deficiency were more likely to be infected with COVID-19 than those without the deficiency (odds ratio, 5,155).
“Perhaps the most important finding is that vitamin D deficiency increases the risk of developing COVID-19 after adjustment for age, “write the authors. Before concluding:” Prospective intervention studies are needed to validate the hypothesis that vitamin D supplementation may be useful for the prevention and treatment of COVID-19 “.
