The Impact of Sleep Quality and Daytime Sleepiness on Global Quality of Life in Community-Dwelling Patients With Heart Failure

Abstract

With the exception of the environmental domain (P = .078), poor sleepers had significantly lower scores in physical (P < .001), psychological (P = .001), and social (P = .040) domains of the WHOQOL-BREF. Multivariate regression analysis revealed that age, CPSQI, perceived health status, and comorbidities significantly predicted the physical QOL (adjusted R2 = 0.59, P < .001). For the psychological QOL, only perceived health status and CPSQI score remained in the regression model (adjusted R2 = 0.28, P = .016). For the environmental QOL, perceived health status and Epworth Sleepiness Scale were the only predictors remaining in the model (adjusted R2 = 0.17, P < .001). The findings from this study add support to the evidence that in medically stable persons with HF, poor sleep independently predicts the overall perception and satisfaction with life, in particular, in the physical and psychological domains of QOL, whereas daytime sleepiness independently predicts the environmental QOL.
