A Prognostic Model for COPD Complicated With Sarcopenic Obesity Based on Bioelectrical Impedance Phase Angle Technology
China200 participantsStarted 2025-08-01
Plain-language summary
This study aims to explore the diagnosis, impact, and prognostic factors of COPD complicated with sarcopenic obesity using multi-segment bioelectrical impedance phase angle technology. It seeks to clarify the diagnostic value and efficacy of body composition analysis in specific populations, analyze the relationship between phase angle and COPD severity as well as quality of life, investigate its predictive role for adverse outcomes, and reveal the effects of inflammation and metabolic disorders in sarcopenic obesity. The goal is to provide a basis for early screening and precise intervention to improve patient prognosis.
