Objectives：The purpose of this study is to determine the factors affecting sleep problems and assess the relationship between sleep quality and quality of life in hemodialysis patients.
Methods：One hundred forty three patients participated in this study. The Pittsburgh Sleep Quality Index(PSQI) and World Health Organization Quality of Life Scale Abbreviated Version(WHOQOL-BREF) were used to assess sleep quality and quality of life respectively. The psychological status was measured using Hospital Anxiety and Depression scale(HADS).
Results：The percentage of poor sleepers was 74.8%. The mean of all WHOQOL-BREF domains in the poor sleeper were significantly lower than in the good sleepers. The factors showing statistical difference between good and poor sleepers were Body Mass Index(p=0.035), Calcium(p=0.049), Kt/V(p=0.001), HADS-Depression(p=0.045), HADS-Anxiety(p＜0.001) and HADS-Total(p＜0.001). The PSQI score correlated positively with phosphorus, kt/V, Urea reduction ratio(URR), HADS-Anxiety(HADS-A), HADS-Depression(HADS-D) and HADS-Total(HADS-T) and correlated inversely with all domain except social relationships and overall QOL. Multiple linear regression analysis revealed that phosphorus and HADS-Total were independent variables associated with PSQI score.
Conclusion：Our results demonstrated that sleep problems are common and associated with decreased quality of life in hemodialysis patients. We propose the management of psychological factors as well as medical factors affecting sleep problems to improve the quality of life of hemodialysis patients.
