Appendicular Intracellular Water Index Measured by Bioelectric Impedance Spectroscopy (BIS) as a Potential Surrogate for DXA-Measured Appendicular Lean Mass

Introduction: Proposed consensus definitions of sarcopenia include lean mass measurement; thus generally requiring a whole body DXA. As this is not available everywhere and is not portable, there are situations where sarcopenia assessment is impractical. Consequently, we evaluated the potential of a mobile tool, bioelectric impedance spectroscopy (BIS), to assess muscle mass for sarcopenia determination. We hypothesized that BIS-measured appendicular intracellular water index (as a surrogate for muscle mass) corrected by height (aICW/ht2) would correlate well with ALM/ht2 and potentially allow establishment of a sarcopenia cut-point for aICW/ht2.
