WEDNESDAY, June 30, 2021 (HealthDay News) — Poor sleep is associated with increased risks of all-cause and cause-specific mortality, with risk exacerbated among those with insufficient physical activity (PA), according to a study published online June 29 in the British Journal of Sports Medicine<\/em>.<\/p>\n Bo-Huei Huang, from the University of Sydney, and colleagues examined the joint association of PA and sleep with all-cause and cause-specific mortality risks among 380,055 participants with a mean age of 55.9 years from the U.K. Biobank. Based on current public health guidelines, baseline PA levels were classified as high, medium, low, and no moderate-to-vigorous PA (MVPA). Sleep was classified into healthy, intermediate, and poor. Twelve PA-sleep combinations were derived, and the mortality risks were ascertained.<\/p>\n The researchers found that sleep scores showed dose-response associations with all-cause, total cardiovascular disease (CVD), and ischemic stroke mortality after an average follow-up of 11.1 years. Compared with the reference group (high PA\/healthy sleep), the highest mortality risks were seen for the no MVPA\/poor sleep group for all-cause, total CVD, total cancer, and lung cancer (hazard ratios, 1.57, 1.67, 1.45, and 1.91, respectively). Lower PA amplified the deleterious associations of poor sleep with all outcomes, apart from stroke.<\/p>\n “Our results support the value of interventions to concurrently target PA and sleep to improve health,” the authors write. “Future prospective studies with device-based sleep and PA assessments and trials concurrently targeting both behaviors are warranted.”<\/p>\n
