This study aimed to investigate the link between prolonged sedentary bouts and health-related quality of life (QOL) in patients on chronic hemodialysis (CHD). A total of 84 outpatients on CHD, aged 71.6±11.8 years, were enrolled in this cross-sectional study. Parameters for prolonged sedentary bouts [i.e., ≧ 30 min (% and bout) and ≧ 60 min (% and bout)] were measured using a triaxial accelerometer. Health-related QOL (HRQOL) was evaluated by the Euro-QOL (EQ-5D). Clinical parameters were obtained from medical records. Relatively prolonged sedentary bouts (%) were 44.0±18.2 (≧ 30 min) and 29.8±16.5 (≧ 60 min) for total days. Prolonged sedentary bouts (bouts) were 6.2±2.7 (≧ 30 min) and 2.7±1.6 (≧ 60 min) for total days. EQ-5D scores were 0.728±0.220. All prolonged sedentary bout parameters were negatively correlated with EQ-5D scores, except for prolonged sedentary bouts (≧ 60 min) (min) and relatively prolonged sedentary bouts (%) on hemodialysis days. Multiple regression analysis showed that prolonged sedentary bout parameters were an important factor in EQ-5D scores even after adjusting for confounding factors for total and non-hemodialysis days. Our results suggested that prolonged sedentary bouts were closely associated with HRQOL in patients on CHD, especially on non-hemodialysis days.
