Long-Term Mortality Risk in Older Adults with Sarcopenia: an 11-Year Prospective Cohort Study Comparing AWGS 2014 and AWGS 2019 Guidelines for Enhanced Clinical Utility and Accurate Risk Prediction

To discern the diagnostic accuracy between the updated diagnostic consensus of the Asian Working Group for Sarcopenia (AWGS) in 2019 (AWGS 2019) and the previous AWGS 2014 guidelines. A prospective population-based cohort study. The study included 731 older community-dwelling adults aged ≥ 65 years who participated in face-to-face interviews and were followed up for 11-year mortality until 31 Mar 2022. We utilized a handgrip strength dynamometer to measure participants’ muscle strength, while their walking speed was determined by a timed 6-meter walk test at their usual pace. Additionally, muscle mass was measured using dual-energy X-ray absorptiometry scanning. Sarcopenia was defined as the presence of low muscle mass in combination with weakness and/or slowness both by AWGS 2014 and 2019 criteria. The present study followed 731 participants (mean age 73.4 ± 5.4 years, men predominant 52.8
