Association of Vitamin D Status and Other Clinical Characteristics With COVID-19 Test Results.

ABSTRACT:

Importance

Vitamin D treatment has been found to decrease the incidence of viral respiratory tract infection, especially in patients with vitamin D deficiency. Whether vitamin D is associated with coronavirus disease 2019 (COVID-19) incidence is unknown.

Objective

To examine whether the last vitamin D status before COVID-19 testing is associated with COVID-19 test results.

Design, setting, and participants

This retrospective cohort study at an urban academic medical center included patients with a 25-hydroxycholecalciferol or 1,25-dihydroxycholecalciferol level measured within 1 year before being tested for COVID-19 from March 3 to April 10, 2020.

Exposures

Vitamin D deficiency was defined by the last measurement of 25-hydroxycholecalciferol less than 20 ng/mL
