Waist circumference gives a better prediction of diabetes risk than BMI, according to researchers at the German Institute for Nutritional Research in Potsdam-Rehbrucke.
Silke Feller and her colleagues concluded that predictive power of waist circumference for diabetes is particularly high for normal and underweight people (BMI less than 25).
Persons with a BMI of less than 25 points, but with a large waist circumference, have just as high a risk of developing diabetes, as pre-obese (BMI between 25- 30) women and men with low waist circumference.
Visceral fat can be more accurately assessed from the waist circumference with people of lower weight than with overweight people, as waist circumference in overweight people contains a high proportion of subcutaneous fat.
The conclusion is mentioned in the current edition of Deutsches Arzteblatt International.
