Honing in on abdominal fat — as opposed to measuring a person's overall mass — is a more accurate way to predict a person's cardiovascular risk, they say. To analyze how well their new model predicts mortality risk, the researchers applied it to data on more than 11, subjects from the National Health and Human Nutrition Examination Surveys from to This BMI replacement still has problems.

When it comes to health research, "simplicity trumps accuracy," they write:. Over the same period, BMI has been mentioned more than 34, times!

But there's also another issue: that we shouldn't use any one number to paint a picture of our overall health. These tools can be useful for developing nationwide statistics, but perhaps shouldn't be used to evaluate an individual's health.
Another limitation of SBSI, the researchers note, is that it could be affected by myriad other things that potentially define our health, such as smoking, pregnancy, socio-economic status and ancestry.

If his waist expanded to 42in or 60 per cent of his height, he risked losing 1. An average year-old, 5ft 4in tall woman risked dying 1.
If her waist increased to 51in, she could die Professor Les Mayhew of Cass Business School said the latest findings highlighted the need for an urgent review of how obesity is measured. Focusing on WHtR, which is more globally useful than waist circumference, will identify those with central obesity and ensure resources are focused on those most at risk.
