雅思阅读材料：体重指数真的主要准吗

If you’re one of the legions of slim, fit and healthy people whose BMI (Body Mass Index) makes them ‘technically’ overweight, this story will be music to your ears. A new test is about to launch — called the ABSI.

很多人BMI指数(身体质量指数)“超重”，实际上却健康苗条。如果你也是其中的一员的话，那么下面的这个新研究可能会让你觉得很中听。一种新的测试体重的指数诞生了。

BMI is calculated by dividing your weight (in kilograms) by your height (in metres) squared. It has been widely criticised for years.

BMI指数(身体质量指数)的测量方式是：体重(千克)/身高(厘米)的平方。而近年来，这一指数受到的非议颇多。

‘The BMI is flawed because it doesn’t take into account where you carry fat or how muscular you are,’ says Sue Baic, a dietician from Bristol University. ‘A woman with a fat stomach, thick waist and skinny arms and legs could be deemed a healthy weight — yet people who carry fat around their mid-section are more at risk of heart disease, diabetes and even certain cancers.’

来自布里斯托大学的营养学家Sue Baic表示，“BMI指数是有缺陷的，因为它没有办法说明人体内有多少脂肪或多少肌肉。比方说，一名女性她肚子肥大却四肢纤细，而她的BMI指数有可能显示的就是健康。然而，腰腹部肥胖的人群患心脏病、糖尿病和某些癌症的危险性更大。”

To calculate your ABSI you take your waist measurement (in centimetres) and divide that by the square root of your height (in centimetres) multiplied by the square of the cube-root of your BMI.

而新推出的ABSI指数是这么计算得出的：腰围(厘米)/[身高(厘米)的平方根乘以BMI的立方根的平方]。

‘It’s a very complicated formula!’ says Sue. ‘But an online calculator is in development. I think it’s a brilliant measure of how healthy you are and it could end up replacing BMI.'

营养学家Sue表示，“这是一个很复杂的公式，但是网络计算器发展得很快，可以帮你算出来。这是个天才的计算方式，能够告诉你，你到底有多健康。以后它会代替BMI指数的。”
