Probable respiratory sarcopenia and 9-year mortality in community-dwelling older adults: the first longitudinal evidence from the CHARLS.

ABSTRACT: a position paper by the Japanese Working Group for Respiratory Sarcopenia (JWGRS). However, the clinical values of probable RS remain unclear. Therefore, we conducted a longitudinal study to determine its impacts on short- and long-term all-cause mortality. Our data were extracted from the China Health and Retirement Longitudinal Study. A total of 5,006 participants were selected as a cohort in 2011, and followed up until 2020. According to the JWGRS, probable RS was defined as a coexistence of low respiratory muscle strength and low appendicular skeletal muscles (ASM) mass. Hazard ratios (HRs) for all-cause mortality and cause-specific mortality were calculated through Cox regression analyses. After an average of 9 years of follow up, 1,176 of the 5,006 participants (23.49%) died. Cox pro
