Abstract [en]

Introduction: Previous studies have examined the relationship between initiation sleep difficulties and quality of life. However, when reviewing the literature in this area we found no reports of a relationship between evening physical activity and health related quality of life in patients with coronary disease. This study was designed to investigate assumed sleep, circadian rhythm, evening physical activity and health related quality of life.

Methods: Twenty-six men and 21 women, mean age 64.0 (SD 8.9) years and 63 (SD 9.3) years, respectively, with stable angina pectoris were included. For assessment of health related quality of life the patients completed the SF36 questionnaire. The data were compared with those for men and women in the general Swedish population. Physical activity was continuously recorded at home, using actigraphy with an integral light recorder (Model AW-L, Cambridge Neurotechnology Ltd, UK) in 1-minute epochs during one week. The data were downloaded by Actiwatch Reader and imported to the Actiwatch software for Windows 98.

Results: Average time of going to bed was 22.37, sleep latency 27 minutes, assumed sleep duration 7.59 hr, time in bed 8.56 hr and sleep efficiency 79.2%. No differences were found during the seven nights. Nonparametric analysis of the circadian rhythm showed that 39 of 47 patients had the lowest 5-hour count activity onset at 00.00 p.m. and 41of 47 patients had the maximal 10 hr count onset 08.00 a.m. or later. Sleep analysis indicated reduced activity in the evening (p.m. 06.00-09.00). Some actigraphic parameters of the evening activity associated significantly with circadian rhythm parameters. Compared to the general Swedish population, the patients ́ health related quality of life waspoor. Linear stepwise regression analysis showed that reduced activity 3 evenings/week significantly explained health related quality of life in32.3% of role function outcome, due to physical causes (p=0.0001) and in 24.7% (p<0.01) of social function, whereas reduced activity 2 evenings/week explained 20% (p<0.01) of body pain.

Conclusions: These data indicate that sleep-activity profile is associated with health related quality of life in patients with stable angina pectoris.
