雅思阅读材料：体重指数真的准吗

　　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。”
