We aimed to evaluate the longitudinal clinical relevance of 3 sarcopenia definitions in the Korean population. Patients and methods: We conducted comprehensive geriatric assessments for 1,379 community-dwelling older participants in the Aging Study of PyeongChang Rural Area (ASPRA) cohort and followed them up prospectively for death, institutionalization, and disability every 3 months. Sarcopenia was defined using the Asian Working Group consensus algorithm, combining grip strength, gait speed, and muscle mass.Results: Among 1,343 participants (mean age: 76 years, 741 women) analyzed, there were 29 deaths and 89 institutionalizations during 22.0 ± 8.3 months follow-up (mean ± SD). All three muscle indices correlated to age and sex. All sarcopenia criteria with muscle mass indices of height, weight, and body mass index (BMI) adjustment significantly predicted death or institutionalization. However, when adjusted for age and sex, only the sarcopenia criteria with muscle mass index of height adjustment were significantly associated with major adverse health outcomes.Conclusion: Adjusting age and gender, the sarcopenia definition from the quintile-based muscle index of height adjustment could predict death or institutionalization in Korean community-dwelling older adults.
