Abstract

The aim of this study was to investigate the relationship between physical activity and health-related quality of life (HRQOL) in patients on chronic hemodialysis. A total of 31 men (69.0±11.1years) and 17 women (66.9±10.0years) among 61 male and 30 female patients on chronic hemodialysis at Innoshima General Hospital, Onomichi, Japan, were enrolled in this cross-sectional study. Physical activity was evaluated using tri-axial accelerometers. HRQOL and psychological distress were also evaluated using the EuroQol questionnaire (EQ-5D) and the K6 questionnaire, respectively. Physical activity evaluated by Σ[metabolic equivalents×h per week (METs·h/w)] was 8.1±6.0 METs·h/w, and EQ-5D score was 0.754±0.177. Among all patients, EQ-5D scores were significantly correlated with physical activity over 4 METs on non-hemodialysis treatment days (r=0.426, p=0.003). In women, EQ-5D scores were also correlated with physical activity over 4 METs on hemodialysis treatment days and non-hemodialysis treatment days. By stepwise multiple regression analysis, physical activity over 4 METs on non-hemodialysis treatment days was a determinant factor of EQ-5D even after adjusting for age and K6 scores. Physical activity over 4 METs on non-hemodialysis treatment days might be associated with EQ-5D in patients on chronic hemodialysis, especially in women.

Highlights

Patients on hemodialysis are dramatically increasing and this has become a public health challenge in Japan
Physical activity evaluated by R[metabolic equivalents 9 h per week (METsÁh/w)] was 8.1 ± 6.0 METsÁh/w, and EQ-5D score was 0.754 ± 0.177
EQ-5D scores were significantly correlated with physical activity over 4 METs on non-hemodialysis treatment days (r = 0.426, p = 0.003)

Summary

Results

Physical activity (METsÁh/w) Physical activity on hemodialysis treatment days (METsÁh/w) Physical activity on non-hemodialysis treatment days (METsÁh/w) Physical activity over 4 METsÁh/w (METsÁh/w) Physical activity over 4 METsÁh/w on hemodialysis treatment days (METsÁh/w) Physical activity over 4 METsÁh/w on non-hemodialysis treatment days (METsÁh/w). Step counts (steps per day) Daily step counts on hemodialysis treatment days (steps per day) Daily step counts on non-hemodialysis treatment days (steps per day) Physical activity (METsÁh/w) Physical activity on hemodialysis treatment days (METsÁh/w) Physical activity on non-hemodialysis treatment days (METsÁh/w) Physical activity over 4 METsÁh/w (METsÁh/w) Physical activity over 4 METsÁh/w on hemodialysis treatment days (METsÁh/w) Physical activity over 4 METsÁh/w on non-hemodialysis treatment days (METsÁh/w). Among all patients on chronic hemodialysis, only physical activity over 4 METs on non-hemodialysis. 8 treatment days was a determinant factor of EQ-5D [EQ-5D scores = 0.043
