Heart disease continues to be the leading cause of death for both men and women in the United States, and it is also one of the leading causes of disability. As part of American Heart Month, we offer insight from our clinicians and researchers about how to reduce your heart disease risks and what new things we’re learning about cardiovascular disease and treatment.

New Brigham and Women’s Hospital (BWH) studies are bringing to light the serious health impact of a sedentary lifestyle. Physical inactivity leads to a shorter life expectancy and increased risks of many chronic diseases. In fact, it causes as many premature deaths worldwide as tobacco smoking or obesity.
A recent study led by BWH epidemiologist Dr. I-Min Lee estimates that physical inactivity causes between six and ten percent of coronary artery disease, type 2 diabetes, colon cancer, and breast cancer cases worldwide. Inactivity also is responsible for some 5.3 million deaths worldwide each year – comparable to the 5 million deaths worldwide per year that are attributed to tobacco smoking or the 3 million deaths worldwide per year attributed to obesity. Physical inactivity was defined in the study as not getting the recommended amount of physical activity, which is 150 minutes per week of moderate-intensity physical activity (e.g., 30 minute brisk walk, 5 times a week).
“Physical inactivity has a major health effect globally,” said Dr. Lee, the lead author of the study. “While it is unrealistic to suppose that we can eliminate inactivity worldwide, a decrease in the number of people worldwide who are inactive by just 25 percent could save as many as 1.3 million lives worldwide each year.”
