Do moderate or high levels of physical activity reduce the risk of heart failure across all levels of body mass index?
Physical activity provides a protective effect against heart failure risk regardless of a person's body mass index.
General overweight and general and abdominal obesity are independently associated with an increased risk of HF, whereas moderate or high levels of physical activity are associated with a reduced risk of HF. The protective effect of physical activity on HF risk is observed at all levels of body mass index.
