Purpose - The coronavirus disease 2019 (COVID-19) is an infectious disease that puts strain on health-care systems. Obesity is considered as a risk factor for the severity of infection. Hypotheses also suggested some nutritional supplements may be useful in COVID-19. This paper aims to assess the role of body mass index (BMI) and nutritional supplements on the severity of COVID-19. Design/methodology/approach - This research was conducted on 603 participants (in five groups including: exposure to virus and healthy, COVID-19 positive patients with severity of mild, moderate, severe and death from COVID-19), in age 18 to 65 years. Demographic data and history of nutritional supplements were asked. Anthropometric measurements were measured in a healthy group and in a patient. They were collected by referring to patients' medical records. Findings - The mean of BMI in groups with severity symptoms of moderate (27.57 kg/m(2)), severe (29.70 kg/m(2)) and death persons (28.13 kg/m(2)), was significantly higher than healthy (26.70 kg/m(2)) and mild symptoms (26.57 kg/m(2)) groups (p = 0.001). The logistic regression shown, the fourth quartile of BMI was significantly associated with occurrence of COVID19, odds ratios (ORs) and 95 confidence intervals (CI): OR: 1.81, (95% CI: 1.13- 2.89), p-for trend = 0.55. There was no significant difference in the percentage of vitamin C, D3, Zinc, Iron and multivitamin supplements intake, between groups, in the past six months (p = 0.11). Originality/value - This study indicated the role of higher BMI in the occurrence and severity of COVID-19. Researches are not enough to recommend consumption of nutritional supplements for the prevention of COVID-19.
