Validation of Phase Angle Cutoff Values Derived From Bioelectrical Impedance Analysis for Sarcopenia Screening in Community-Dwelling Older Korean Adults

Sarcopenia, characterized by progressive loss of skeletal muscle mass and function, poses a significant risk to the aging population. This study aimed to validate the efficacy of phase angle (PhA) derived from bioelectrical impedance analysis (BIA) as a screening tool for sarcopenia in community-dwelling middle-aged and older Korean adults.
