Abstract
Background and objectives: The outbreak of COVID-19 has created a global public health crisis. Little is known about the predisposing factors of this infection. The aim of the current study was to explore an association between the serum vitamin D level, obesity and underlying health conditions, and the vulnerability to COVID-19 in the Iranian population.
Methods: We conducted a case-control study of 201 patients with coronavirus infection and 201 controls. Cases and controls were matched for age and gender. The study was carried out for 2 months (February 2020 to April 2020) at Imam Khomeini Hospital Complex, Tehran, Iran. Serum 25(OH) vitamin D was measured using enzyme-linked immunosorbent assay method. Information containing age, gender, clinical symptoms, body mass index (BMI), CT scan findings, and underlying health conditions related to each participant were elicited from health records.
Results: A significant negative correlation (p = 0.02) was observed between the serum vitamin D level and developing coronavirus infection. Also, the results showed that the COVID-19 cases were more likely to be overweight than the controls (p=0.023). Diabetes mellitus, hypertension, and respiratory infections were found in 20.89%, 9.65%, and 6.96 % of cases, respectively. These underlying health conditions were not significantly different between cases and controls (p= 0.8111).
Conclusions: Vitamin D deficiency and obesity are two main predisposing factors associated with the vulnerability to coronavirus infection in Iranian population. This article is protected by copyright. All rights reserved.
