Reclassification and prevalence of sarcopenia based on the Asian Working Group for Sarcopenia 2025 criteria versus the 2019 version in hospitalized older adults
Retrospective study compares sarcopenia prevalence in hospitalized older adults using AWGS 2025 and 2019 criteria, indicating significant reclassification changes.
Key Points
This research aims to compare the prevalence of sarcopenia using the new AWGS 2025 criteria versus the previous 2019 version among hospitalized older adults.
Single-center retrospective study in a university hospital geriatric ward in Japan
Primary cohort included 289 older adults aged ≥65 with data on BMI, ASM, grip strength, and gait speed
Secondary cohort of 387 older adults with BMI, ASM, and grip strength data was also analyzed.
Sarcopenia prevalence increased from 39.1% (AWGS 2019) to 48.1% (AWGS 2025) among the primary cohort
Thirty-two participants (11.1%) were reclassified from non-sarcopenia to sarcopenia under the new criteria
Secondary cohort showed a prevalence of 51.9% with newly identified low muscle mass in 15.8% attributed to BMI adjustment.
