The Relationship Between Sleep Quality and Quality of Life in Hemodialysis Patients: A Cross-sectional Correlational Study

Abstract

Background: Patients undergoing hemodialysis typically have a low quality of life (QoL), making it essential to address multiple aspects of their well-being. Objectives: This study aimed to investigate the association between QoL and sleep quality in hemodialysis patients at Ali Ibn Abi Taleb Hospital in Zahedan, Iran. Methods: In this cross-sectional study, 86 hemodialysis patients referred to Ali Ibn Abi Taleb Hospital in Zahedan were selected using convenience sampling. Data were collected using a standard quality-of-life (QoL) questionnaire and the Pittsburgh Sleep Quality Index (PSQI). Data were analyzed using the Pearson correlation coefficient in SPSS version 22. Results: Among the 86 patients, 35 (40.7%) had very poor QoL, 41 (47.7%) had poor QoL, and 10 (11.6%) had good QoL. Poor sleep quality (PSQI score > 5) was observed in 66 patients (76.7%). The mean PSQI score was 17.9 ± 7.2. Pearson correlation analysis showed a significant inverse association between the global PSQI score and QoL (r = -0.249, P = 0.0039). Conclusions: Poor sleep quality is highly prevalent among patients receiving hemodialysis and is significantly associated with lower QoL. These findings underscore the need for healthcare providers to implement targeted interventions to improve sleep quality and, consequently, health-related quality of life (HRQoL) in this population.
