Incidence of new-onset sarcopenia and associated factors in stroke patients on a convalescent rehabilitation ward

Abstract

Objective: To elucidate the incidence of new-onset sarcopenia and associated factors in stroke patients on a convalescent rehabilitation ward.

Subjects and Methods: This retrospective cohort study involved consecutively admitted stroke patients without sarcopenia on admission. The incidence of new-onset sarcopenia, diagnosed in accordance with the Asian Working Group for Sarcopenia 2019 criteria, was investigated during hospitalization on our convalescent rehabilitation ward. Factors associated with the onset of sarcopenia were investigated by logistic regression analysis.

Results: From a total of 147 hospitalized patients (99 men, mean age 63.7 years), 14 (9.5%) developed sarcopenia during their hospital stay. Age, energy sufficiency rate, and skeletal muscle index on admission were identified as factors associated with new-onset sarcopenia.

Conclusion: Age, energy sufficiency rate, and skeletal muscle index on admission are possible predictors of sarcopenia onset while hospitalized on a convalescent rehabilitation ward.
