BIS aICW is correlated with DXA-measured ALM directly, and when height adjusted. An aICW/ht2 cut-point of 6.5 L/m2 identified 70% of women with low ALM/ht2. Women with low lean mass by DXA and BIS had poorer function measured by jump power. These pilot data support further evaluation of BIS measurement inclusion into sarcopenia definitions.
