We evaluated their effects on sarcopenia classification among Thai older adults.Methods: This cross-sectional study included 8,073 community-dwelling adults aged \u226560 years attending a tertiary geriatric outpatient clinic. Low muscle mass and sarcopenia were classified using AWGS 2019 and 2025. Discordant ASM\/height\u00b2- and ASM\/BMIbased phenotypes were characterized, and age- and sex-adjusted associations with handgrip strength and gait speed were examined.Results: Low muscle mass prevalence increased from 43.2% under AWGS 2019 to 44.6% after applying the revised AWGS 2025 ASM\/height\u00b2 cutoffs and to 51.4% after including ASM\/BMI. Sarcopenia prevalence increased from 15.1% to 17.5% and 19.7%, respectively. ASM\/BMI identified 547 additional participants with low muscle mass. Participants with isolated low ASM\/BMI had greater overall and central adiposity than those with isolated low ASM\/height\u00b2. ASM\/height\u00b2 was positively associated with handgrip strength (standardized \u03b2=0.262, p&lt;0.001), whereas ASM\/BMI was positively associated with gait speed (standardized \u03b2=0.122, p&lt;0.001). Neither index was consistently superior across outcomes.Conclusion:AWGS 2025 broadened low muscle mass and sarcopenia classification through revised age-specific cutoffs and ASM\/BMI, which identified a complementary adiposity-related phenotype.<\/jats:p>","DOI":"10.4235\/agmr.26.0128","type":"journal-article","created":{"date-parts":[[2026,8,25]],"date-time":"2026-08-25T07:48:56Z","timestamp":1787644136000},"page":"400-409","update-policy":"https:\/\/doi.org\/10.4235\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Clinical
