Abstract
A growing number of studies from a range of different countries have observed an association between sleep duration and cardiovascular disease. The objective of this paper was to examine the associations between sleep duration and prevalent cardiovascular disease in a large sample of Australian adults, and identify the sociodemographic and health-related factors moderating these associations. Participants included 218155 Australian adults aged 45years and over. The results indicated that 6h versus 7h sleep was associated with increased odds of heart disease [odds ratio (OR)=1.11 (1.06-1.17)], diabetes [OR=1.15 (1.09-1.22)], stroke [OR=1.25 (1.14-1.38)] and high blood pressure [OR=1.08 (1.04-1.11)]. Long sleep (≥9h sleep) was also related to elevated odds of heart disease [OR=1.14 (1.09-1.19)], diabetes [OR=1.25 (1.19-1.31)], stroke [OR=1.50 (1.38-1.62)] and high blood pressure [OR=1.04 (1.01-1.08)] compared to 7h sleep. Some of these relationships varied by age, and were not evident in adults aged 75years and over. The magnitude of some associations varied significantly by body mass index, smoking and physical activity. These findings provide further insight into the nature of the relationship between sleep and cardiovascular health.
