Measurement of Body Fat Mass, Fat-Free Mass, and Muscle Mass Measured using Bioelectric Impedance and Dual-Energy X-Ray Absorptiometry

In this research, we discussed the bone density by measuring the total bone mineral density, fat mass and lean mass in a sample of Mosul people, as soon as to compare the accuracy of the BIA approach to DXA in assessing total body compartments and segmental tissue mass. A cross sectional study conducted at DXA laboratory, Physiology Department, College of Medicine, Nineveh University, Mosul-Iraq. A total of 136 persons, 44 males and 92 women, recruited from reviewing of college Medical College Academic Centre and took part in the current study. A highly statistically significant association between BIA and DXA measures for TFM, TLM, and FFM was also found. BIA underestimates total fat mass by 7.24 kg than DXA. BIA approach overestimated muscle mass by 10.1 kg when compared to the DXA. BIA underestimates fat-free mass by 20.67 kg compared to DXA.
