Normative reference values of the phase angle for Korean population: an analysis of the Korea National Health and Nutrition Examination Survey.

ABSTRACT:

Background

Phase angle (PhA) reflects fluid balance and cellular membrane integrity within the human body. Establishing normative reference values for PhA is crucial for research and clinical purposes.

Objectives

This study aimed to establish normative reference PhA values in a representative sample of the Korean population and determine the cutoff values for diagnosing sarcopenia in older adults.

Methods

This cross-sectional analysis included the data of 4,881 individuals aged 10-80 years. Multi-frequency bioelectrical impedance analysis was employed for PhA measurements. Sarcopenia was defined according to the Asian Working Group for Sarcopenia 2019 guidelines. The Lambda-Mu-Sigma method was applied to create centile curves and tables. Sensitivity, specificity, and
