Abstract

Objective To investigate the correlation of body fat distribution measured by dual-ener gy X-ray absorptiometry (DEXA) and uric acid among males with abdominally obese,and then compare it with anthropometric obesity indices.Methods This study included 88 males with abdominally obese (waist circumference ≥90 cm,abdominally obese group) and 60 non-abdominally obese men (waist circumference <90 cm,control group) aged between 20 and 50 years.In the multiple linear regression model,body fat distribution was the dependent variable,anthropometric obesity indices ( model 1 ) and DEXA-derived parameters (model 2 ) were independent variables.Results The uric acid level of the abdominally obese group [ (389.3 ± 78.8 ) μmol/L vs.( 324.9 ± 61.5 ) μmol/L ] were significantly higher than that of the control group (P < 0.01 ).Uric acid was positively correlated with anthropometric obesity indices (r =0.390 ~ 0.496,P < 0.01 ) and the indices from DEXA ( r =0.377 ~ 0.459,P < 0.01 ).In model 1,24.6% of the total variance of uric acid was due to waist to hip ratio.In model 2,trunk fat mass explained 21.0% of the total variance of uric acid.Conclusions Body fat distribution was closely correlated with the uric acid level in adult men.Both measurements for body fat distribution,DEXA and anthropometric obesity indices,were correlated with uric acid levels,however,the former was not superior to the latter.
