Objective: The aim of the study was to investigate the association between dialysis shift and subjective sleep quality in chronic haemodialyzed patients. Design: A cross-sectional observational study. Participants and methods: A total of 206 haemodialyzed patients aged from 22 to 71 participated in this study. Participants were grouped into the morning-shift and other-shifts groups. Subjective sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI). All participants also completed the Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BAI). Results: Dialysis shift significantly predicted the PSQI score with patients receiving morning-shift haemodialysis having better sleep quality ( β= 0.15, p= 0.01). Other independent predictors of the PSQI score included depression ( β= 0.42, p <0.001), anxiety ( β= 0.38, p <0.001), and tea drinking ( β= 0.20, p0.001). Together these factors explained 48.2% of the variance in the PSQI score. Conclusion: Morning dialysis shift was significantly associated with better subjective sleep quality in chronic haemodialyzed patients after adjusting for other confounders.
