People with obesity who are hospitalised with Covid-19 have a significantly higher rate of ICU admissions and longer duration of ICU stay compared to people with a normal body mass index (BMI), suggest the findings of a recent study.

The study was presented virtually at ENDO 2021, the Endocrine Society's annual meeting.

"The association between obesity and a more severe clinical course of Covid-19 highlights the vulnerability of this population during the current pandemic and the need for public health efforts to prevent and treat obesity, in the current pandemic and beyond," said lead researcher Yu Mi Kang, M.D., PhD, of Yale-New Haven Health in New Haven, Conn.

More than 40% of Americans live with obesity, one of the significant risk factors for Covid-19. Kang and colleagues wanted to determine and describe the impact of obesity on the clinical course of Covid-19, compared with individuals who do not have obesity.

The researchers analyzed data from 3,268 adult patients hospitalized with Covid-19 at five hospitals within the Yale-New Haven Health System between March and November 2020.

Among hospitalized patients, 43 per cent had obesity, 15.8 per cent died, and 24.2 per cent required ICU-level care. Patients with obesity were 26 per cent more likely to need ICU care overall than patients who did not have obesity. Covid-19 patients with higher body-mass index (BMI) measurements were even more likely to require ICU care. Individuals with severe obesity, or a BMI of 40 or higher, were twice as likely to need ICU care compared with patients with a normal BMI. The study did not find a higher risk of death in people with obesity compared to those with normal BMI.

"Our work underscores the impact of obesity on the course of Covid-19 and emphasizes the need to ensure that obesity is given appropriate consideration for risk stratification, vaccination protocols and in-hospital Covid-19 management," Kang said.
