“If we look at the prevalence of obesity based upon 2018 numbers, which is the latest that we see from the CDC, we know that 42.4% of U.S. adults have the disease of obesity. That's almost half,” said Fatima Cody Stanford, MD, MPH, assistant professor of medicine and pediatrics at Harvard Medical School. She added that many people have seen their weight increase during the pandemic, “so that 42.4% may actually be significantly closer to 50%.”
In addition, it’s often thought that kids are much less susceptible to COVID-19, but here again overweight plays a role. Children experiencing bad outcomes often have obesity, requiring ventilation or extracorporeal membrane oxygenation, or ECMO.
“This is an issue across the age spectrum,” she said.
