Estimates of fat-free mass (FFM) by densitometry, dual energy X-ray absorptiometry (DXA), and bioimpedance spectroscopy (BIS) in caucasian and Chinese-American women.
Estimates of fat-free mass (FFM) from dual energy X-ray absorptiometry and bioelectrical impedance spectroscopy (BIS) were compared to results obtained by densitometry in a group of Caucasian and Chinese-American women. Each group included 38 women between the ages of 18 and 24 years. The Chinese-American women were significantly shorter in stature, had lower body weights, and lower values for FFM compared to the Caucasian women. DXA estimates of FFM were consistently lower than those obtained from densitometry; BIS estimates were similar to densitometry results.
