The purpose of this study is to examine the validity and reproducibility of impedance body fat measurement devices measuring the body com-position of Korean male and female adults using three bioelectrical im-pedance analyzers. We compared two methods for evaluating body composition: dual energy X-ray absorptiometry (DEXA), and bioelectri-cal impedance analysis (BIA). Subjects were 200 healthy adult Korean males and females whose mean±standard deviation (range) age, standing height, body weight, and body mass index (BMI) were 44.1±14.5 years, 172.8±7.4 cm, 76.0±12.8 kg, and 25.4±3.3 kg/m2, and 44.5±14.7 years, 158.7±5.8 cm, 58.3±8.3 kg, and 23.2±3.0 kg/m2, re-spectively. As a result, first of all, the reproducibility of the bioelectrical impedance analyzer had very high coefficients at r=0.998, r=0.997 be-tween men and women, respectively. The correlation coefficients among three comparisons for lean body mass (LBM) were provided the following coefficients: r=0.951 for DEXA vs. ACCUNIQ BC720, r=0.950 for DEXA vs. ACCUNIQ BC360, and r=0.946 for DEXA vs. ACCUNIQ BC380 in men. In the results for women, they also had the very high fol-lowing coefficients: r=0.956 for DEXA vs. ACCUNIQ BC720, r=0.946 for DEXA vs. ACCUNIQ BC360, and r=0.957 for DEXA vs. ACCUNIQ BC380 in LBM. In conclusion, this research showed a higher correlation in terms of accuracy compared to existing BIA-based body composition measurement techniques, and the accuracy of LBM was improved with high correlation coefficients through the algorithm that was improved using the multifrequency BIA method in the ACCUNIQ BC products.
