Background: Previous studies have revealed that sedentary behavior, including quantitative and qualitative parameters, was associated with health-related quality of life (HRQOL) in patients on chronic hemodialysis.

Objective: The present study examined the relationships between various parameters of prolonged sedentary bouts on non-hemodialysis days and HRQOL in patients on chronic hemodialysis.

Methods:  A total of 110 patients (47.2%) on chronic hemodialysis (64 men and 46 women, aged 71.4 ± 11.2 years) among 233 patients, who were outpatients at a hospital in Hiroshima prefecture, Japan, were enrolled in this cross-sectional study. Prolonged sedentary bouts were evaluated using a tri-accelerometer, i.e., sedentary behavior (minutes), median sedentary bouts (minutes), maximum sedentary bouts (minutes), sedentary bouts (bouts and minutes/bout), and prolonged sedentary bouts (≥5, ≥10, ≥30, and ≥60 minutes; bouts and minutes/bout). HRQOL was assessed using EuroQol 5-Dimension (EQ-5D).

Results:  The EQ-5D score was 0.755 ± 0.216. All prolonged sedentary parameters, except for sedentary bouts (bouts), correlated with HRQOL, and higher correlation coefficients were observed between sedentary behavior (minutes) and HRQOL (r = -0.416) and between maximum sedentary bouts (minutes) and HRQOL (r = -0.436) than between other parameters. These parameters were also identified as factors affecting HRQOL, even after adjustments for confounding factors.

Conclusion:  In summary, sedentary behavior (minutes) and maximum sedentary bouts (minutes) on non-hemodialysis days, which may be representative of quantitative parameters for sedentary behavior, correlated with HRQOL in patients on chronic hemodialysis.
