Associations Between Changes in Physical Activity and Risk of All-Cause Mortality in Adults With/Without Hypertension - China, 2010-2022.

What is already known about this topic?: Previous studies indicate that an increase in physical activity can diminish the risk of mortality. However, the relationship between longitudinal changes in physical activity and health improvement among Chinese adults with or without hypertension has not been explored.

What is added by this report?: This study found that increasing or maintaining moderate to high physical activity levels reduced the risk of all-cause mortality, irrespective of the baseline physical activity level. In addition, the beneficial effects were particularly pronounced in people with hypertension.

What are the implications for public health practice?: It may be beneficial to encourage adults in China, especially those with hypertension, to actively increase physical activity and deter the issue of physical inactivity that accompanies aging.
