[目的]本研究采用基于磁共振成像的生物电阻抗分析技术(BIA)测量日本男性和女性的骨骼肌质量(SMM)，为确定骨质疏松症的诊断界点收集SMM数据。研究了不同性别和不同身体部位的年龄相关SMM变化的差异。[研究对象]受试者为1,347名日本男性和女性(男622名，女725名)，年龄18-84岁。[方法]按性别和年龄对上肢、小腿和全身肌肉质量测量结果和SMM指数(SMI)计算结果进行比较。[结果]计算男性和女性身体各部位的肌肉质量丢失率，女性的上臂肌肉质量和SMI的丢失率明显较低。男性为4.0 kg/m2，女性为2.9 kg/m2。[结论]本研究结果表明，虽然男性和女性都有肌肉质量丢失，但男性的肌肉丢失率更高。目前的研究结果还表明，BIA值可能会因测量仪器的不同而不同。
[Purpose] In this study, bioelectrical impedance analysis (BIA), based on magnetic resonance imaging, was used to measure the skeletal muscle mass (SMM) of Japanese male and female, in order to gather SMM data for setting cut-off points for the diagnosis of sarcopenia. Differences in age-associated SMM changes according to sex and body part were investigated. [Subjects] The subjects were 1,347 Japanese male and female (622 male, 725 female) aged 18–84 years. [Methods] The results of arm, leg, and whole-body muscle mass measuremalets and SMM index (SMI) calculations were compared by sex and age. [Results] Calculations of the rate of muscle mass loss for each body part in male and female revealed a markedly low rate of loss in arm muscle mass and SMI in female. Cutoff points were 4.0 kg/m2 for male and 2.9 kg/m2 for female. [Conclusion] The present findings demonstrate that, although muscle mass loss occurred in both male and female, muscle loss rates were greater in male. The present findings also suggest that BIA values might differ depending on the measuring instruments.
