Introduction: The potential risk of obesity on the severity of COVID-19 has been proposed. The
main purpose of this study was to investigate the effect of BMI on the survival rate of COVID-19
patients admitted to the ICU.
Methods & materials: Patients with COVID-19 admitted to ICU were included. Gender, height,
weight, BMI, age, underlying disease status, prescribed drugs and nutritional supplements, and
clinical and laboratory parameters at the beginning of admission were recorded. Death or
discharge from the ICU and the days elapsed to these events were also reviewed and recorded.
Data analysis was performed using the Cox regression model.
Results: assessing 193 patients showed that BMI was not related to the survival rate even after
adjusting for other potential confounding variables. It was shown that arterial oxygen saturation
and taking Famotidine were the significant factors determining the time to event in these patients.
Conclusion: The BMI at the time of ICU admission has no effect on survival rate and time to event
in COVID-19 infected patients admitted to ICU.
