Objective: This study aimed to investigate the correlations of sarcopenia with phase angle（PhA）and timed up and go test（TUG）in patients on maintenance hemodialysis（MHD）. Methods: A total of 133 patients（median age = 67.3［59.3-72.7］years, 89 males）who underwent hemodialysis 2-3 times per week between July and September 2019 at Oyokyo Hirosaki Hospital were included. Subject demographic and clinical data were collected. Handgrip strength（HGS）and TUG were measured. Body composition was measured using bioelectrical impedance analysis to determine appendicular skeletal muscle mass（ASM）and PhA. Diagnostic criteria from the Asian Working Group for Sarcopenia 2019（AWGS2019）were used for confirming sarcopenia. Logistic regression analysis was used to examine the factors associated with sarcopenia. Single correlation analysis and multiple regression analysis were used to examine the factors associated with PhA and TUG. Results: The prevalence of sarcopenia was 37.6%. Predictors for sarcopenia were age, body mass index（BMI）, and PhA. Factors associated with PhA were HGS, creatinine, the geriatric nutritional risk index（GNRI）, and HD vintage, while factors associated with TUG were age, BMI, and PhA. Conclusion: PhA is a predictor of both sarcopenia and TUG, and the predictors of TUG are the same as those of sarcopenia.
