A Comparison of the Physical Activity and Sedentary Behavior between Autologous and Allogeneic Hematopoietic Stem Cell Transplantation Survivors

OBJECTIVE: The treatment background, as well as the frequency and type of complications, in autologous (auto-) and allogeneic (allo-) hematopoietic stem cell transplantation (HSCT) survivors influence the appearance of moderate to vigorous physical activity (MVPA) or sedentary behavior. We therefore assessed differences in the MVPA and sedentary behavior between auto- and allo-HSCT survivors. METHODS: This prospective observational study included 13 auto- and 36 allo-HSCT survivors (approximately 4 years after HSCT). The MVPA and sedentary behavior were assessed using a triaxial accelerometer. RESULTS: There were no significant between-group differences in the MVPA or sedentary behavior (p=0.768 and 0.739, respectively). In allo-HSCT survivors, the MVPA was negatively correlated with the Hospital Anxiety and Depression Scale score (r=-0.358, p=0.032). A stepwise multiple regression analysis showed that age was a significant predictor of sedentary behavior in allo-HSCT survivors (β=0.400, p=0.016). CONCLUSION: We observed no significant between-group differences in the MVPA or sedentary behavior. Our results suggest that it may be unnecessary to change the rehabilitation program according to the donor type in interventions for promoting MVPA and reducing sedentary behavior in long-term HSCT survivors.
