Increased risk for COVID-19 in patients with vitamin D deficiency – Science Direct

Vitamin D deficiency is strongly associated with increased risk for coronavirus disease 2019 (COVID-19).

The odds ratio for COVID-19 increases with vitamin deficiency in black individuals.

Diabetes, obesity, and periodontal disease are associated with an increased risk for both COVID-19 and vitamin D deficiency.

Patients with vitamin D deficiency were 4.6 times more likely to be positive for COVID-19 (indicated by the ICD-10 diagnostic code COVID19) than patients with no deficiency (P < 0.001). The association decreased slightly after adjusting for sex (odds ratio [OR] = 4.58; P < 0.001) and malabsorption (OR = 4.46; P < 0.001), respectively. The association decreased significantly but remained robust (P < 0.001) after adjusting for race (OR = 3.76; P < 0.001), periodontal disease status (OR = 3.64; P < 0.001), diabetes (OR = 3.28; P < 0.001), and obesity (OR = 2.27; P < 0.001), respectively. In addition, patients with vitamin D deficiency were 5 times more likely to be infected with COVID-19 than patients with no deficiency after adjusting for age groups (OR = 5.155; P < 0.001).

Vitamin D sufficiency, a serum 25-hydroxyvitamin D at least 30 ng/mL reduced risk for adverse clinical outcomes in patients with COVID-19 infection – PLOS ONE

…it is recommended that improving vitamin D status in the general population and in particular hospitalized patients has a potential benefit in reducing the severity of morbidities and mortality associated with acquiring COVID-19.

Vitamin D reduces infection and impact of COVID-19, studies find – Sky News

  • Patients with sufficient levels of vitamin D are less likely to experience complications and die from COVID-19
  • It has also been found to reduce infection rates.
  • Vitamin D sufficiency was linked with a significantly decreased level of inflammatory markets, and higher blood levels of immune cells, in new research from Boston University’s school of medicine.
  • In patients older than 40, those who had sufficient levels of vitamin D were more than 51% less likely to die than patients who were deficient.
  • Sufficient vitamin D can reduce the risk of catching the coronavirus by 54%, the vitamin can also help against other viruses affecting the upper respiratory tract.
