Chronic diseases such as heart disease, cancer, stroke, and diabetes are conditions that can develop slowly and worsen over a long period of time. These conditions are responsible for a great deal of illness, disability, and decreased quality of life for millions of Americans. Chronic diseases account for more than 75% of medical care costs in the U.S., and a majority of all deaths each year in the state and nation. Several factors play a part in the development of these diseases. Some factors are genetic, environmental, and behavioral. Behaviors such as tobacco use, eating habits, and physical activity are strongly linked to chronic diseases.
