Chronic diseases—heart disease, cancer, chronic obstructive pulmonary diseases and stroke—are the leading causes of death in the United States. Seven of every 10 deaths in the U.S. result from chronic conditions. Heart disease is the leading cause of death among both men and women, followed by cancer and chronic obstructive pulmonary diseases—stroke is fourth, diabetes is seventh. Chronic, disabling conditions cause major limitations in activity for more than one of every 10 Americans, or 25 million people. Chronic diseases also are costly to states, yet they are among the most preventable of health problems.
