Overview

Cross-sectional analysis finds lower phase angle and elevated ECW/TBW relate to muscle function decline, suggesting a new screening method.

Key Points

  • Lower phase angle and elevated ECW/TBW ratio are significantly associated with poor muscle function, highlighting a potential risk factor for aging adults.
  • The odds ratio for low physical function in the lower phase angle/elevated ECW/TBW group was 3.07, indicating a significant health risk.
  • Bioelectrical impedance analysis was used to measure phase angle and ECW/TBW in 695 community-dwelling participants aged 50 and older.
  • These findings suggest that combined BIA profiles may help identify older adults at high risk for functional decline in community settings.
