The researchers discovered that the danger of worse outcomes from COVID-19 begin rising in individuals with a BMI above 23 kilogrammes per sq. metre (kg/m2), which is taken into account to be within the wholesome vary. The dangers of hospitalisation had been 5 per cent greater for each unit enhance in BMI and the danger of ICU admission was 10 per cent greater for every unit enhance, they stated.

Increasing BMI had little or no impression on the danger of extreme COVID-19 in individuals aged over 80 years, the researchers stated. However, the general incidence of extreme COVID-19 amongst individuals aged 20 to 39 years of age was decrease than all different age teams, they stated.

“Our study shows that even very modest excess weight is associated with greater risks of severe COVID-19 complications and the risks rise sharply as BMI increases,” stated Carmen Piernas, lead writer of the examine, from the University of Oxford.

The researchers famous a number of limitations to their examine.

The evaluation of the impression of BMI could also be restricted by the smaller pattern of individuals with latest BMI measurements, they stated.
