In a recent study published in PLOS ONE, researchers found in patients with COVID-19, a high body mass index (BMI) is associated with an increased risk of death and prolonged intensive care unit (ICU) stay.
The study is from the University of Gothenburg. One author is Lovisa Sjögren.
Previous studies have shown that a high BMI is a risk factor for severe COVID-19.
Obesity increases the risk of comorbidities such as type 2 diabetes and hypertension and has been shown to increase the need for mechanical ventilation in association with other respiratory infectious diseases such as influenza and pneumonia.
In the study, the team analyzed data on 1,649 COVID-19 patients from the Swedish Intensive Care Registry, a national quality registry that covers all ICUs in Sweden.
The patients included in the study were admitted to ICUs during the first wave of the COVID-19 pandemic, between March 6 and August 30, 2020, 96% had a positive PCR test for the SARS-CoV-2 virus or a clinical diagnosis of COVID-19, were all over the age of 18, and had current weight and height data available.
A majority of the study cohort had a high BMI; 78.3% were overweight or had obesity.
There was a strong link between increasing BMI and the composite outcome of death during intensive care, or an ICU stay of longer than 14 days in survivors.
Individuals with a BMI of 35 kg/m2 or more were twice as likely to have one of the outcomes of death or prolonged ICU stay, adjusted for age and sex.
Moreover, this association remained after adjusting for the presence of cardiovascular disease, hypertension, diabetes mellitus, liver or kidney disease, as well as after adjusting for severity of illness at ICU admission.
The researchers conclude that obesity is an independent risk factor for a severe outcome from intensive care in patients with COVID-19 and suggest that BMI be included in the severity scoring for COVID-19 ICU patients.
