What is this? COVID-19 patients with comorbidities, such as obesity, may be at higher risk for poorer outcomes.

In this rapid review, the authors searched for studies of the effect of body mass index (BMI) on the need for critical care for COVID-19 patients. They restricted their searches to articles published in English or Indonesian and did their most recent search on 14 April 2020. They included three retrospective cohort studies (806 patients) from China, France and the USA; and rated the quality of evidence in each study as high.

What was found: At the time of the review, the included studies showed that COVID-19 patients with obesity may have an increased need for invasive mechanical ventilation compared to normal weight COVID-19 patients.

At the time of the review, the included studies showed that younger COVID-19 patients (<60 years) with obesity grade I and II had increased rate of hospitalization and increased need for critical care compared to normal weight and obese group patients.

At the time of the review, the included studies showed that obese individuals should be treated as a higher risk population and that obesity can increase the susceptibility of people to develop severe COVID-19.
