Abstract :
Bioelectrical impedance analysis (BIA) method has been commonly used for measuring human body composition, especially body fat rate. In this study, we developed PDA based body fat measurement system using BIA method. A regression model for predicting fat free mass (FFM) was developed. Sixty-three weighted stable subjects (53 men, 10 women) aged 20∼32 years old participated in this study. A regression model, FFM = 0.0005*height2 - 0.0160*impedance + 0.3920*weight - 0.0684*age - 5.8141*sex + 25.984, was found. The correlation coefficient of body fat rate between our system and HTM1000plus(Bionet™) was 0.928. HTM1000plus was approved from KFDA (Korean Food & Drug Administration) and it was a commercial product. These results indicated that our system is a reliable for estimation of body fat rate.
