The risk of greater COVID-19 severity and death is higher in people with any obese body mass index (BMI), according to a study to be published in the European Journal of Endocrinology. The study findings showed that BMI over 30 was associated with a significantly higher risk of respiratory failure, admission to intensive care and death in COVID-19 patients, regardless of age, gender and other associated diseases. The current guidelines for identifying those at higher risk in the UK are set at a BMI of 40 but these data suggest people with BMI over 30 should also be classified as at risk.
