Introduction
Sarcopenia is an involuntary decline in skeletal muscle mass, strength, and function that normally proceed with aging but may develop faster under some chronic disease conditions. In this study, we compared the physical activity between sarcopenia and non-sarcopenia subgroups in kidney transplant recipients.
Methods
Fifty-eight recipients (42 males and 16 females) were enrolled in this study. Mean age of the recipients was 46.6 ± 12.7 years. Mean duration of dialysis was 2.8 ± 4.0 years. Diagnostic criteria for sarcopenia referred to those of the Asia Working Group for Sarcopenia. The physical activity was assessed using the International Physical Activity Questionnaire, and the intensity of physical activity was expressed in metabolic equivalents (MET).
Results
Based on the skeletal muscle mass index (SMI) as well as functional index (HGS, walking speed), the participants were classified into the three subgroups: 12 patients (20.7%) with sarcopenia (Group 1), 25 (43.1%) with presarcopenia (Group 2), and 21 (36.2%) non-sarcopenia (Group 3). Analysis with ANOVA and pairwise comparisons showed that physical activity measured as total MET-min/week was significantly greater in Group 2 (1292 ± 633) than in Group (1484 ± 262). Moreover, physical activity of Group 3 (2461 ± 1339)-min/week was significantly greater than those of Groups 1 and 2.
Conclusions
Our data indicate that physical activity is restricted under presarcopenia and sarcopenia after kidney transplantation. Considering that the recipient age is now increasing, proper management of sarcopenia may become more crucial to improve the kidney survival and lifetime prognosis of the kidney transplant recipients.
