Waist-to-hip ratio 'better than BMI' at predicting over-70s mortality
Waist-to-hip ratio is a better predictor of all-cause mortality than body mass index in those over 70, according to US research, the latest to criticise BMI as a measure.
The study, of 1,189 active adults in their 70s and found no association between BMI or waist size alone and all-cause mortality over 12 years.
But there was an association for the waist to hip ratio. For every 0.1 increase in the waist to hip ratio of women, there was a 28% increase in all-cause mortality.
In men there was a 75% increase in the mortality rate for those with a waist to hip ratio above 1.
