Diagnostic Criteria of Sarcopenia and Their Associations With Functional Performance in Older Adults

Abstract

Background/Objectives: Sarcopenia, characterized by age-related muscle loss, impacts functional performance and mobility. This study compares sarcopenia prevalence and physical fitness outcomes among older adults using four criteria from European and Asian Working Groups. Methods: A total of 377 community-dwelling older adults all of Taiwanese ethnicity, were recruited for this study. They completed seven functional assessment tests. Descriptive statistics and various tests were used to compare variables between older adults with and without sarcopenia. Correlation and logistic regression analyses, along with the area under the curve, were performed to evaluate relationships between sarcopenia criteria and functional assessments, as well as the impact of functional performance on sarcopenia classification. Statistical significance was set at p
