{diamondsuit} Objectives: Sleep disorders are common in end-stage renal disease patients. This study examined the relationship between self-reported quality of sleep (QoS) and certain psychosocial domains for patients on peritoneal dialysis (PD).

{diamondsuit} Methods: The study subjects included 190 PD patients from 7 urban dialysis clinics in Northern Taiwan, from whom we obtained biochemical parameters and demographic data. QoS, quality of life (QoL), religious/spiritual activity, and depression were assessed using the Pittsburgh Sleep Quality Index (PSQI) questionnaire, Medical Outcomes Study Short Form (SF-36) for QoL, the Royal Free Questionnaire, and the Beck Depression Inventory, respectively.

{diamondsuit} Results: The average PSQI score was 9.1 ± 4.1 and, in total, 85.8% of all patients were poor sleepers (global PSQI ≥5). There was no difference in age, gender, and mode or duration of PD between good and poor sleepers. Biochemical data did not differ between the two groups. Widowed patients experienced significantly poorer QoS than patients with other marital status (PSQI scores: 12.3 ± 4.9 vs 8.88 ± 4.0, p = 0.006). The percentage of patients that held a bachelor's degree or above was significantly higher in good sleepers (55.6% vs 29.4%, p = 0.008). The PSQI value correlated negatively with the QoL scale in both physical (r = –0.295, p < 0.001) and mental domains (r = –0.410, p < 0.001), and correlated positively with the depression scale (r = 0.351, p < 0.001). There appeared to be no association between QoS and spiritual/religious activity (r = –0.097, p = 0.223).

{diamondsuit} Conclusions: Psychosocial factors including depression, patients' perceptions regarding QoL, marital status, and educational background correlated significantly to the subjective QoS for PD patients. When dealing with sleep disorders in PD patients, physicians should pay considerable attention to their psychosocial backgrounds.

KEY WORDS: Quality of sleep; spiritual and religious activity; depression; psychosocial factors; quality of life; marital status; education.
