Meeting Canadian 24-Hour Movement Guideline recommendations and risk of all-cause mortality

Abstract

This study determined if meeting the Canadian 24-Hour Movement Guidelines recommendations are associated with all-cause mortality. Participants were 3471 adults from the 2005–2006 U.S. National Health and Nutrition Examination Survey followed for mortality over 11 years. They were classified as meeting or not meeting recommendations for sleep duration, sedentary behaviour, and moderate-to-vigorous physical activity (MVPA). A total of 63.8%, 35.3%, and 41.5% of participants met recommendations for sleep, sedentary behaviour, and physical activity while 12.3% met all 3 recommendations. The hazard ratio (HR) for all-cause mortality in participants meeting the recommendations relative to those not meeting the recommendations were 0.91 (0.72, 1.16) for sleep, 0.92 (0.61, 1.40) for sedentary behaviour, and 0.42 (0.24, 0.74) for MVPA. The HR for meeting none, any 1, any 2, and all 3 recommendations were 1.00, 0.86 (0.65, 1.14), 0.49 (0.28, 0.86), and 0.72 (0.34, 1.50). When the cut-point used to denote acceptable sedentary time was changed from ≤8 to ≤10 hours/day, the HR for meeting none, any 1, any 2, and all 3 recommendations were 1.00, 0.83 (0.59, 1.15), 0.57 (0.34, 0.96), and 0.43 (0.20, 0.93). These findings provide some support of the ability of the 24-hour Movement Guidelines to predict mortality risk.
