Body weight and age affect covid symptoms, study reveals

People considered to be in the upper regions of the ‘healthy’ BMI range are still at increased risk of developing severe Covid-19, an Oxford study has found.

A healthy BMI is between 18.5 and 25 but the new study shows that for every point over 23, a person’s risk of hospitalisation from Covid increases by five per cent. They are also ten per cent more likely than their slimmer peers to need intensive care treatment.

But the risk is more significant in younger adults. Someone aged between 20 and 39 is nine per cent more at-risk of hospitalisation for every BMI point over 23.

They are also 13 per cent more likely to be admitted to ICU and 17 per cent more likely to die than if they had a BMI of 23 or lower.

As a result, the study authors suggest obese and overweight people should be prioritised for inoculation instead of using age to distinguish priority when it comes to handing out vaccines.

Analysis of almost seven million anonymised health records of people living in England revealed 13,503 Covid-19 patients who needed hospital care between 24 January and 30 April 2020.

University of Oxford scientists compared a patient’s BMI with their Covid battle and found risk of severe disease increased with bodyweight.

Previous studies have found obese people are more at-risk of severe disease and death from Covid-19 but this is the first study to look at the entire BMI range.

It revealed that body weight and age are correlated to disease risk.

The relationship was shown to be more pronounced in younger adults despite lower case numbers overall. 

For example, people between 20 and 39 are nine per cent more likely to be hospitalised for every BMI point over 23, but for someone over 80 the risk increase is just one per cent.

As a result, a 25-year-old person with a BMI of 25, the upper limit of the ‘healthy’ range, according to the British NHS, is two BMI points above the 23 threshold.

This means that if they were to catch coronavirus, they are 18 per cent more likely to be hospitalised than someone who has a BMI of 23.
