Study shows 'obesity paradox' does not exist: Waist-to-height ratio is a better indicator of outcomes in patients with heart failure than BMI

New research has debunked the idea that there is an 'obesity paradox', whereby patients with heart failure who are overweight or obese are thought to be less likely to end up in hospital or die than people of normal weight. The study, which is published in the European Heart Journal, shows that if doctors measure the ratio of waist to height of their patients, rather than looking at their body mass index (BMI), the supposed survival advantage for people with a BMI of 25kg/m2 or more disappears.
