Approximately 75% of the $3 trillion currently spent on health care in the United States is attributable to cancer, heart disease, type 2 diabetes, and obesity, and each of these conditions is strongly influenced by behavior. Nearly one-half of patients prescribed medications to lower their cholesterol within 1 year following myocardial infarction stop taking these drugs—even when they are provided free of charge. Despite great advances in the science and technology of health care, a large gap separates theoretically achievable goals in health and health care from what individuals and populations actually reach. Human behavior is both a major contributor to health problems and a barrier to the successful implementation of solutions to address them.
