Researchers in France found almost half of 124 patients admitted to an intensive care unit (ICU) with COVID-19 had a BMI in the obese range. This was nearly double the rate of a comparison group of ICU patients with severe acute respiratory disease unrelated to COVID-19.

Further, the need for mechanical ventilation increased with increasing BMI.

A UK surveillance study of patients admitted to intensive care with COVID-19 reported almost three-quarters (75%) of the 6,720 patients had a BMI in the overweight or obese range, which is greater than the population prevalence of overweight and obesity in adults in the UK (around 67%).

One study of 3,615 people who tested positive for COVID-19 found those aged under 60 years with a BMI of between 30 and 34 were almost twice as likely to be admitted to ICU compared to patients with a BMI of less than 30. This likelihood increased to 3.6 times in those patients with a BMI of 35 or greater
