Correlates of objective sleep quality in older peritoneal dialysis patients

Abstract

Background Sleep disturbance is a prominent concern in dialysis patients and detrimentally impacts clinical and self-reported health outcomes. This study aimed to collect sleep data from in-home actigraphy and to explore possible predictors of sleep quality in older peritoneal dialysis patients. Methods This was a cross-sectional study. Peritoneal dialysis patients aged ≥60 years participated in this study. For each participant, sleep quality was assessed by analyzing the data produced by an actigraphic device worn on the wrist 24 h a day for seven consecutive days. Physical function was assessed using handgrip strength and the Timed Up and Go test. Depression was assessed using the self-reported Geriatric Depression Scale. Multiple linear regression analyses were performed to examine the factors influencing sleep efficiency and sleep time. Results Based on data collected from 50 participants ( N = 50, mean age 70.4 years, 70% male), including 333 nights of actigraphy-monitored sleep, the mean sleep efficiency was 75.5%±14.2% and the mean total sleep time 391.0 ± 99.3 min per night. Higher hemoglobin (β = 0.38, p = 0.007) and lower serum phosphorus (β = −0.30, p = 0.042) levels were significant predictors of better sleep efficiency. The only significant predictor of the total sleep time was age (β = 0.32, p = 0.021). Conclusion Older peritoneal dialysis patients had poor sleep, characterized by low sleep efficiency. Low hemoglobin and high serum phosphorus levels were predictors of poor sleep efficiency and, as such, modifiable factors for clinicians to consider when treating patients with sleep complaints.

The influence of social support on sleep and fatigue level among patients receiving hemodialysis in Saudi Arabia: a cross-sectional correlational design

“…These age-related alterations can exacerbate sleep difficulties in older HD patients. In line with this study, poor sleep quality and reduced sleep efficiency were both identified in elderly patients on peritoneal dialysis (Zhang et al, 2021).…”

Association between negative psychology and sleep quality in dialysis patients during the COVID‐19 pandemic

“…The resulting tension is a crucial factor contributing to poor sleep quality (De Silva et al, 2021). (ii) More than half of the subjects in this survey were elderly, and advanced age was associated with an increased likelihood of sleep difficulties (Viola et al, 2012; Zhang et al, 2021). (iii) comorbidities such as restless legs syndrome and dialysis adequacy in patients with kidney disease are important contributors to the severity of sleep problems in this population (Kalantar‐Zadeh et al, 2022; Örsal et al, 2017).…”

Health-Related Quality of Life Sleep Score Predicts Transfer to Hemodialysis among Patients on Peritoneal Dialysis

“…Sleep disorders in patients on PD include altered sleep architecture, sleep apnea, restless legs syndrome, periodic limb movement disorder, and excessive daytime sleepiness [ 27 ]. In elderly patients undergoing PD, higher hemoglobin and lower serum phosphorus were significantly correlated with better sleep efficiency, and age was the only significant predictor of the total sleep time [ 28 ]. Furthermore, although APD is more likely to interrupt sleep compared with CAPD, it has been considered effective for sleep apnea [ 29 ].…”
