Abstract: Objective Through analysis of related indexes of body fat to find the correlation of fat and serum uric acid.Methods The 466 blood samples were collected from a hospital for detection of SUA,T G,TC,HDL-C,LDL-C,VLDLC,and indexes including height,body weigh,waist circumference(WC),hip circumference(HC),waist-to-heigh ratio(WHTR),waist-to-hipratio(WHR),BM I,body fat percentage(BF%)were measured.Results The indexes of TG,TC,LDL-C were increased and HDL-C had decreased trend in hyperuricemia group.The related indexes of body fat,body weight,WC,HC,WHTR,WHR,BM I were increased in hyperuricemia group,and BF% was increased in age groups above 30.There are positive correlations in SUA with TG,VLDL-C,body weight,waist circumference,hip circumference,waistto-heigh ratio,BM I and negative correlation in SUA with HDL-C.There are positive correlations in SUA with BF% in men and women.We used assessment method of obesity to divide the samples into two groups,there is variance between the two groups.Conclusion The hyperuricemia is correlated with metabolic disorder and obesity.The mechanism of the relation between obesity and serum uric acid may be related with content of internal organs grease.Using BF%,waist-to-height ratio,BM I,waist-to-hip ratio to assess obesity and get the message of grease distribution,there will be great significance on risk prediction of hyperuricemia which related to blood fat.
