Not smoking

Researchers examining the relationship between cigarette smoking and smoking cessation on mortality during a decades-long perspective study of over 100,000 women found that approximately 64% of deaths among current smokers and 28% of deaths among former smokers were attributable to cigarette smoking.

Maintaining a healthy weight

A study showed that middle-aged women and men who gained 11 to 22 pounds after age 20 were up to three times more likely to develop heart disease, high blood pressure, type 2 diabetes, and gallstones than those who gained five pounds or fewer.


A study showed that, among women ages 50 to 79 with no cardiovascular disease at the start of study, prolonged sitting time was associated with increased heart disease risk regardless of the amount of time spent in leisure-time physical activity.

Follow a healthy diet

A study found that those who adhered most to healthy eating patterns had a 14 to 21% lower risk of cardiovascular disease when compared with those who adhered least.
