Association between Skeletal Muscle Mass Index and Convalescent Rehabilitation Ward Achievement Index in Older Patients

OBJECTIVE: The aim of the current study was to investigate the association between the skeletal muscle mass index (SMI) and the convalescent rehabilitation ward achievement index (CRWAI) in older patients with functional impairment. METHODS: in women); we then evaluated the association between SMI and the CRWAI score. RESULTS: Of the 319 recruited patients, 84 (26%) were in the high SMI group. The medians and interquartile ranges of the CRWAI scores in the high SMI and low SMI groups were 38.6 (23.1-61) and 31.8 (10.1-57.5), respectively (P=0.029). A high SMI was independently and negatively associated with the CRWAI score (β=- 0.16, P=0.014). CONCLUSIONS: Our study showed that a high SMI was an independent factor negatively influencing the CRWAI score in older patients in a convalescent rehabilitation ward.
