Background: Phase angle (PhA) is a cell health marker and has been associated with muscle mass and strength in non-kidney disease individuals. However, it is unknown whether PhA is a predictor of sarcopenia and its components in kidney transplantation patients. Aim: The aim of the present study was to associate the PhA with sarcopenia and its components in kidney transplantation patients. Methods: One hundred and twenty nine kidney transplantation individuals were evaluated in a cross-sectional study. Phase angle and muscle mass were obtained using bioelectrical impedance. Handgrip strength (HGS) was performed with a hand dynamometer; and the functional capacity with 4-meter walking test. Sarcopenia was diagnosed according to the European Consensus Diagnostic Criteria for Sarcopenia. Participants were subdivided according to the median values of PhA (6.1º and 6.6º for women and men, respectively). Results: Individuals with lower PhA values showed higher odds to present low HGS (OR = 3.71; 95% CI: 1.101-12.516), after adjustments for sex, age, weight, height, and use of immunosuppressive drugs. However, lower PhA was not associated with sarcopenia (OR = 1.25; 95% CI: 0.486-3.239), low muscle mass (OR = 0.52; 95% CI: 0.185- 1.440), and functional capacity (OR = 1.61; 95% CI: 0.341-7.647). Conclusion: Phase angle was associated with HGS but not with sarcopenia and its other components. These results suggest that PhA can be used as a possible predictor of muscle strength in kidney transplantation patients.
