Prevalensi Sarkopenia pada Lansia di Komunitas (Community Dwelling) berdasarkan Dua Nilai Cut-off Parameter Diagnosis

Sarcopenia, aging muscle mass loss, and function syndromes can lead to decreased quality of life and increased elderly mortality. The availability of various screening methods and operational definitions in different studies has produced different findings of sarcopenia prevalence. The purpose of this study was to discover the prevalence of sarcopenia in Indonesian community-dwelling elderly based on muscle mass measured by bioimpedance analysis, handgrip strength using hand dynamometer, and physical performance based on six minutes walking test with two different cut-off point parameters of sarcopenia, i.e. the cut-off point recommended by Asian Working Group for Sarcopenia (AWGS) and the cut-off point based on the reference used in Taiwan elderly population reference due to the lack of references for Indonesian elderly population. A cross-sectional study was conducted to 229 participants (71 men and 158 women) from the community-dwelling elderly population between August and December 2014 in Bandung and Jatinangor. The results of the study showed that the sarcopenia prevalence in this study based on AWGS was 9.1% (7.4% in men and 1.7% in women) while the prevalence based on the Taiwan reference revealed a prevalence of 40.6% (20.1% in men and 20.5% in women). This highly different prevalences shows the importance of defining a specific cut-off point for elderly population in community-dwelling Indonesia to get a more accurate sarcopenia prevalence
