Sleep Disorders in Peritoneal and Haemodialysis Patients as Assessed by a Self-Administered Questionnaire

Abstract

Sleep disorders have been reported as a frequent problem in dialysis patients. However, only one paper has compared the prevalence and possible causes of this complication in peritoneal (PD) and haemodialysis (HD) patients. We surveyed 84 PD and 87 HD patients about disordered sleep using a self-administered questionnaire. Forty-nine percent of PD and 56% of HD patients reported problems sleeping. These problems were rated as severe by 29 PD and 22 HD patients. Type of disturbances involved delayed sleeping (13 PD and 32 HD, p< 0.005), interrupted sleep (32 PD and 44 HD) and early morning awakening (25 PD and 37 HD). The number of hours of sleep varied widely among patients: it was 5 and 21 minutes in PD patients with sleep disorders and 7 and 37 min in PD pts without such problems. No statistically significant relationship was evidenced between sleep disorders and age, sex, body weight, obesity, duration of dialysis, dialysis dose, self-assessed sadness, anxiety, worry, pain, pruritus, dyspnoea, restless leg syndrome, use of cigarettes, caffeine, or sleeping pills. In conclusion, sleep disorders are a frequent problem in both PD and HD patients. Apparently the relationship with demographics, dialysis dose, lifestyle and personality traits is poor. The possible role of other causes should be investigated.

Sleep Quality and Depression in Peritoneal Dialysis Patients

“…[29,30] In addition, many studies reported that there was no relationship between SQ and age in PD patients. [3,4,6,7] In the present study, poor sleepers were older than good sleepers, but there was no a significant correlations of global PSQI score with age.…”

“…The prevalence of poor sleep in the present study was 43.5%, similar to the 49-85% prevalence of poor SQ assessed by various kinds of surveys in other studies made on PD patients. [2][3][4][5][6][7] We observed that poor sleepers had a higher BDI score and lower PCS and MCS of QOL, and were older as well. In addition, the percentage of patients holding a high school degree or above was significantly higher in good sleepers (see Table 1).…”

“…[1] A high prevalence of sleep disorders (SD), ranging from 49% to 85%, has been reported in PD patients. [2][3][4][5][6][7] The causes of SD among dialysis patients are not completely understood. A number of earlier studies concerning factors associated with SD in PD patients failed to demonstrate consistent findings.…”

“…A number of earlier studies concerning factors associated with SD in PD patients failed to demonstrate consistent findings. [2][3][4][5][6] Most of these studies reported that there was no significant relationship between sleep quality (SQ) and age, gender, durations of dialysis, hemoglobin (Hb), albumin, parathyroid…”

Sleep Quality and Its Correlates in the First Year of Dialysis

“…Holley et al (17) noted in a study of 48 HD patients that those with sleep disorders were more likely to smoke cigarettes, and a larger cross-sectional study of 833 HD patients found that a history of smoking was associated with a 70% higher risk for sleep disorders. However, these findings were not reproduced in a cross-sectional study of 172 HD and PD patients (48). These studies did not examine change in sleep quality and only partially accounted for potential confounding factors.…”
