Background: To evaluate predictability of body mass index(BMI), waist-to-hip ratio(WHR), and percent body fat(%BF) for metabolic syndrome(MS).
Methods: A total of 1030 adults(708 males, 322 females) diagnosed as fatty liver by ultrasound from a health promotion center during the period between March 2005 and June 2006 were subjects. BMI was measured, and WHR and %BF were assessed using bioelectrical impedance analyzer. MS was defined as having at least three metabolic components (high blood pressure, glucose and TG, and low HDL). BMI levels(<25kg/m2 vs. ≥25kg/m2) and WHR levels(<0.9 vs. ≥0.9 for males, <0.85 vs.≥0.85 for females) were combined to make 4 categories.Applied prominent thesis, journals, studies, and e-media, this review is based on final definitions that has been proven so far.
Results: The odds ratio(95% C.I) for having MS was 1.7(0.9-3.4) in group of high WHR/low BMI, 4.4(2.4-7.7) in group of low WHR/high BMI, 3.9(2.2-6.7) in group of high WHR/high BMI compared to the group of low WHR/low BMI. Using ROC analyses for MS, the cutoff values of BMI, WHR, and %BF were 27kg/m2, 0.93, 24% for males, and 24kg/m2, 0.88, 33% for females, respectively. The sensitivity and specificity were 70~90% and 30~60%, respectively. There were no
significant differences in the area under the curves(AUC) among BMI, WHR, and %BF in males, while AUC for %BF was
significantly lower compared with those for BMI and WHR in females.
Conclusions: Both of BMI and WHR would be useful indicators for predicting MS in adults with fatty liver and BMI of 25kg/m2 would be an adequate cutoff value.
