Is obesity a major risk factor for Covid-19?

Obesity is a major risk factor for covid-19 and people who are obese are more likely than those who are not obese to:

• Contract Covid-19 at a younger age
• Develop severe Covid-19
• Require hospitalization. Studies have shown the risk may be tripled in those who are obese
• Require admission into ICU
• End up in hospital sooner
• Require oxygen
• Require mechanical ventilation
• Require intubation
• Die from Covid-19.

Obesity is linked to impaired immune function, and also decreased lung capacity and reserve, making ventilation more difficult. The increased risk for hospitalization or death is particularly pronounced in those under age 65 with an estimated 30.2% of Covid-19 hospitalizations attributed to obesity.

Children diagnosed with obesity may suffer worse outcomes from COVID-19. In those aged 18 years and younger, having obesity was associated with a 3.07 times higher risk of hospitalization and a 1.42 times higher risk of severe illness.

Hispanic and non-Hispanic Black adults have a higher prevalence of obesity and are more likely to suffer worse outcomes from COVID-19.
