What is the relationship between physical activity and all-cause mortality?
The 2018 Physical Activity Guidelines Advisory Committee Scientific Report found that physical activity is associated with lower all-cause mortality. Studies conducted by the Women's Health Initiative and the Global Burden of Disease Study 2013 have found a dose-response relationship between physical activity and all-cause mortality, meaning that more physical activity is associated with lower mortality. A meta-analysis conducted by Biswas et al. (2015) also found that sedentary behavior is associated with higher all-cause mortality. Thus, increasing physical activity and decreasing sedentary behavior can help reduce all-cause mortality.
