ABSTRACT
Body mass index {BMI) is the most frequently used method İn the assessment of obesity, and its increment is assumed to be an important risk factor for the development of atherosclerosis. Recently, however, several investigators have recommended the use of percentage body fat (PBF), waist circumference (WC) and waist/hip ratio (WHR) instead of BMI. in this study we evaluated the correlations of BMI, PBF, WC and WHR with each others and their effects on the many atherosclerotic risk factors in 169 females (age 42.4 ± 13.4 [mean± SD] years). We observed that WC and WHR have a stronger correlation with sBP (r = 0.49, p = 0.000 and r = 0.51, p = 0.000, respectively), dBP (r = 0.48, p = 0.000 and r = 0.48, p = 0.000, respectively), the presence of hypertension (r= 0.38, p = 0.000 and r = 0.39, p = 0.000, respectively), plasma fasting insulin level (r = 0.48, p = 0.000 and r = 0.44, p = 0.000, respectively), second hour insulin level (r = 0.40, p = 0.001 and r = 0.35, p = 0.004, respectively), first hour glucose level {r = 0.34, p = 0.001 and r = 0.29, p = 0.005, respectively), and second hour glucose level (r = 0.28, p = 0.007 and r = 0.25, p = 0.01, respectively)(during OGTT), triglyceride level (r = 0.37, p = 0.000 and r = 0.40, p = 0.000, respectively), and total cholesterol level (r = 0.23, p = 0.01 and r = 0.31, p = 0.01, respectively) than BMI and PBF. These results suggest that WC and WHR have a stronger correlation with cardiovascular risk factors than BMI and PBF. Although PBF also has an important association with some cardiovascular risk factors, it is not a better predictor of hypertension, NIDDM, or plasma glucose, insulin and lipid abnormalities than BMI.
