Half of all Americans live with at least one chronic disease, such as heart disease, cancer, stroke, or diabetes. Chronic diseases—which are, broadly defined, health conditions that persist for 1 year or longer, that typically require ongoing medical attention, and that can interfere with the activities of daily living (CDC, 2021b)—are a major health concern in the United States and around the world. Chronic diseases are the leading cause of death and disability in the United States and are a leading driver of health care costs (CDC, 2021a).
