Study on Fat Content of Simple Obesity in Adults withDual-energy X-ray Absorptiometry Method(DEXA)

To study the diagnosis of obesity quantitative analysis and the value,120 cases of obesity and the control group,80 cases of normal-weight body fat content were measured by the application of dual-energy,X-ray absorptiometry(DEXA),to study the body fat content and distribution in different ages,gender of obesity patients and normal body mass;explored the DEXA diagnostic indicators in patients with obesity and normal body mass.The results showed that,compared by the relationship between using of DEXA determined fat content and body mass index(BMI)the male correlation coefficient r= 0.871(P0.001),two evaluation methods showed that's good of the consistency;Female correlation coefficient r= 0.521(P0.001),the consistency of the two evaluation methods is in general;diagnosis of simple obesity best cut point for males 19.45 %,34.00 % for females.Therefore,whole body DEXA measurement of body fat content can diagnose obesity and quantitative analysis.
