Predictivity of bioimpedance phase angle for incident disability in older adults.

ABSTRACT:

Background

Bioelectrical impedance analysis (BIA)-derived phase angle is expected to be an efficient prognostic marker of health adverse events with aging as an alternative of muscle mass. We aimed to examine the predictive ability of phase angle for incident disability in community-dwelling elderly and determine the optimal cut-off values.

Methods

Community-dwelling elderly aged ≥65 years (n = 4452; mean age = 71.8 ± 5.3 years, 48.3% women) without disability at baseline participated in this prospective cohort study. Phase angle and appendicular skeletal muscle mass (ASM) were examined using a multi-frequency BIA at baseline. Other potential confounding factors (demographics, cognitive function, depressive symptoms, medications, and physical performance) were also assessed.
