 When compared with Body Mass Index BMI, it was found that the measure of abdominal obesity waisthip rate and waist circumference was the better determinant of chronic diseases such as diabetics and cardiovascular disease. Some evidences in the United States of America indicated that the relation between waisthip rate and AMD gave stronger results when compared with the relation between BMI and AMD. For middle age cohort, after six years of follow-up, a group of researchers reported that the decrease of waisthip rate also decreased the risk of AMD and the results were the same for waist circumference, even if the evidences were weak. In another study, it was reported that the increase of waisthip rate or waist circumference also increased the progression of AMD.
