Aim: The aims of this study were to: (a) describe the physical activity (PA) and quality of life (QOL) in living donor liver transplant (LDLT) recipients pre-operatively and at 3 months and 6 months post-operatively; (b) compare PA and QOL at 6 months post-operatively with a healthy control group; and (c) explore pre-operative factors that predict PA changes. Methods: Patients over 20 years of age who were undergoing LDLT were recruited. PA was measured based on the number of steps/day and time spent performing moderate-to-vigorous PA (MVPA) during 1 week using an accelerometer. QOL was assessed based on a physical (PCS) and mental (MCS) component summary of the eight-item Short-Form Health Survey. The LDLT and healthy control groups were matched for age (±3 years) and gender. Pre-operative factors predicting a change in PA were calculated using a generalized linear mixed model. Results: Twenty-four patients completed the study. By 6 months post-LDLT, the MCS and PCS were comparable to those in the control group. The number of steps (3,887 steps/day) and MVPA (29.3 min/week) showed significant improvement by 6 months post-operatively, but remained much lower compared with those in the control group. The multivariate analysis showed that younger age (p <.01, p =.04) and higher skeletal muscle mass (SMM; p <.01, p =.03) were predictors of improvement in number of steps and MVPA. Conclusion: This study suggests the need for pre-operative interventions by healthcare professionals that focus on outcomes such as improving low SMM to facilitate post-operative PA recovery.
