Why the study?
Do moderate or high levels of physical activity reduce the risk of heart failure across all levels of body mass index?
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.
Supports activity promotion across BMI for HF prevention; hypothesis-generating from observational data, needs RCT confirmation.
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.
