Background: Phase angle is a bioimpedance analysis parameter that indirectly shows body cell mass. Its association with mortality has been shown in patients receiving dialysis treatment. However, assessment with mortality in kidney transplant recipients has not been studied previously. Methods: We examined 158 kidney transplant recipients who underwent bioimpedance analysis 8 years ago in a cross-sectional study. We contacted them again and investigated the presence of cardiovascular events, cancer, angina pectoris, and claudication. Data regarding mortality, graft failure, and creatinine values were collected from recipients' files. Findings: During the follow-up period, 15 recipients died, 26 lost graft function, 36 experienced cardiovascular events, and 4 developed cancer. Phase angle was significantly associated with mortality during the 8-year follow-up period of kidney transplant recipients (P < .001). The cutoff value for phase angle as a predictor of mortality was <= 5.85. Moreover, a phase angle value lower than 5.85 indicated 5.33 times higher risk of mortality. Discussion: Phase angle was a predictor of mortality in kidney transplant recipients. Since phase angle is an inexpensive, easy-to-perform, and noninvasive method, it might be considered as an additional tool to assess survival in kidney transplant recipients.
