Sleep-wake-activity rhythm and health-related quality of life among patients with coronary artery disease and in a population-based sample –an actigraphy and questionnaire study
(English)Manuscript (preprint) (Other academic)
The aim of this study was to explore whether there are gender differences in sleep and health related quality of life in patients with coronary artery disease CAD and a matched population-based sample and to see how subjectively rated sleep is associated with actigraphy. Secondly, whether factors that predict patients´ sleep quality could be identified. Fifty-seven patients with stable CAD and forty-seven participants from a population-based sample were included. All participants completed the Uppsala Sleep Inventory (USI), the Epworth Sleepiness Scale and the SF-36. Actigraphy recordings and a sleep diary were performed for 7 days. Multiple stepwise regression analysis showed that sleep duration, sleep onset latency, nocturnal awakenings, vitality (SF-36) and BMI explained 60% of the sleep quality outcome (USI) (P<0.0001). Sleep duration, sleep efficiency and fragmentation index assessed with actigraphy and sleep diary accounted for 36% of the sleep quality outcome (diary, P<0.0001). The result can form the basis for a non-pharmacological, self-care programme supported and led by nurses.
