Chronic diseases account for 7 of every 10 U.S. deaths and for more than 60% of medical care expenditures. In addition, the prolonged illness and disability associated with many chronic diseases decrease the quality of life for millions of Americans.
Much of the chronic disease burden is preventable. Physical inactivity and unhealthy eating contribute to obesity, cancer, cardiovascular disease, and diabetes. Together, these two behaviors are responsible for at least 300,000 deaths each year. Only tobacco use causes more preventable deaths in the United States. People who avoid the behaviors that increase their risk for chronic diseases can expect to live healthier and longer lives.
