PURPOSE: The purpose of this study is to verify the validity of ultrasonic measuring device through body fat percentage test.
METHODS: To achieve this goal, validity tests were performed using the measured values of Dual Energy X-ray Absorptiometry known as the reference method. 58 university students were participating in the study from Gyeonggi-do. Height and weight were measured as well as Body fat percentage using the portable ultrasound device and Dual Energy X-ray Absorptiometry. For data processing, the average and standard deviation of the data were calculated by using SPSS 25.0 program and MedCalc program. Correlation analysis (r) and Bland & Altman were performed to examine the validity of the ultrasound device. In addition, the interpolation and slope were presented in the Bland & Altman results and the mean absolute percentage errors was presented for the verification of accuracy.
RESULTS: In male students, there was a high correlation between the ultrasonie device and Dual Energy X-ray Absorptiometry in male (r=.92) and females (r =.71). The results of the Bland & Altman analysis showed that the confidence interval was stable and that the agreement was high. In the case of male students -13.4 ~ 2.9, the confidence interval range was shown. the mean absolute percentage errors was 28.6%. In the case of women the confidence interval ranged from -8.0 to -1.3, with mean absolute percentage errors of 17.2%.
CONCLUSIONS: As a result, it was confirmed that the body fat rate validity between the ultrasonic measuring device and Dual Energy X-ray Absorptiometry was high.
