Obesity increases the risk of contracting the coronavirus, of landing in the hospital and intensive care unit, and the risk of death from Covid-19, according to a new study from researchers at the University of North Carolina at Chapel Hill.

The researchers say there's also concern a vaccine could be less effective for people with obesity due to a weakened immune response.

Scientists at UNC reviewed data from 75 studies conducted between January and June involving 400,000 coronavirus patients.

They found obese people had a 46% greater risk of catching Covid-19 than non-obese people, and a 113% increased risk of hospitalization.

Plus their chances of ending up in the intensive care unit were 74% greater than those who were not obese. They also had a 48% greater risk of dying from the virus, the team reported Wednesday in the journal Obesity Reviews.
