COVID-19 test positive 4.5 X more likely if had low vitamin D test within 4 years – Jan 6, 2021

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

Nutrition Volume 84, April 2021. https://doi.org/10.1016/j.nut.2020.111106

987,849 patients at University of Florida Hospital
32,000 tested for low vitamin D sometime since Oct 2015
887 Tested positive for COVID-19 in 2020
87 both tested positive and had low Vitamin D

Note: Probably only a small fraction of those with low vitamin D actually were tested
  Medicare, for example, will pay for only a single vitamin D test in a lifetime

Note: Some of the tests will have been done in the Spring, Summer, Fall
   and the person could test OK during that season, but not in the winter

Note: Testing low probably was <20 ng/ml.
   COVID-19 appears to be only fought by Vitamin D when > 30 or 40 ng

The 2019 coronavirus disease (COVID-19) pandemic has disproportionally affected a variety of patients with underlying risk factors such as respiratory and cardiovascular diseases, diabetes, obesity, and black race. Vitamin D deficiency, which can result in a compromised immune response, has been also linked to increased risk and increased morbidities associated with COVID-19. In the absence of large-scale longitudinal studies to determine the strength of association between vitamin deficiency and COVID-19, cross-sectional studies of large patient cohorts can be used.

We used the i2b2 patient's registry platform at the University of Florida Health Center to generate a count of patients using the international classification of diseases (ICD)-10 diagnosis codes for the period of October 1, 2015, through June 30, 2020. Logistic regression of the aggregates was used for the analysis.

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 deficiency is significantly associated with increased risk for COVID-19.
