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.
在一组白种人和华裔美国女性中,对双能X线吸收法和生物电阻抗光谱法(BIS)估算的去脂体重(FFM)与通过密度测定法获得的结果进行了比较。每组包括38名年龄在18至24岁之间的女性。与白种女性相比,华裔美国女性的身高显著更矮,体重更低,FFM值也更低。双能X线吸收法估算的FFM始终低于密度测定法获得的结果;生物电阻抗光谱法的估算结果与密度测定法的结果相似。
