waist-hip ratio (WHR)

waist-hip ratio (WHR)

circumference at the waist divided by that at the hips; an index of body fat distribution, said to be ideally not >0.8 in women and not >0.9 in men, i.e. a low ratio ('pear-shape') is healthier than a high ratio ('apple shape'). Some large-scale studies have found evidence that WHR is a better predictor than body mass index for coronary heart disease.
