Vitamin D Concentrations in Pediatric Patients With COVID-19

This study was conducted on 98 children with confirmed COVID-19 and 2112 patients in a healthy control group. Serum vitamin D levels were significantly lower in the patients with confirmed COVID-19 than in the control group (10.9 ng/dL vs 16.1 ng/dL; P < .001). Almost 65% of patients with inadequate serum vitamin D levels had symptomatic COVID-19, and 30% of patients with adequate vitamin D levels had symptomatic COVID-19 (P = .043). In the logistic model, inadequate vitamin D status was associated with symptomatic COVID-19 compared with asymptomatic COVID-19 (odds ratio = 4032; 95% confidence interval, 1.036-17.776; P = .045).
