Description
Cortés Sierra's team reports a 2026 cross-sectional analysis of body composition readings from one bioelectrical impedance device in routine outpatients. Because each maker's algorithms differ, values from a single platform need their own reference ranges. The team used the SECA mBCA 514 with about 1,850 adults, charting phase angle and skeletal muscle mass by sex and age.
Men showed higher phase angle and muscle mass than women, and both measures fell across older age groups. Women carried a higher fat-to-muscle ratio, and that ratio tracked moderately with lower phase angle. Its link with the device's visceral fat estimate was weak. The authors present the tables as interpretation aids for clinic use, not proof of biological mechanisms.
