Behavior and Biology: The Basic Sciences for AHA Action

It is a privilege and an honor to speak with the scientific community about the need to integrate the behavioral and social sciences with the biomedical sciences and how this relates to the mission of the American Heart Association. My observations and thoughts are influenced by my experiences as a nurse researcher and behavioral scientist at Johns Hopkins, where I have been involved in a research program on high blood pressure control in urban black communities.Tremendous advances in biology are providing new knowledge about genetics, physiology, pathophysiology, and disease, creating exciting opportunities for clinical research. From the laboratory this research evolves into new applications for diagnosis, therapy, and prevention in humans. At the same time, important advances in behavioral science, clinical outcomes, and healthcare delivery have provided needed knowledge about prevention and treatment. This research transitions from the healthcare setting into the community.Individuals’ lifestyles significantly impact their health, with unhealthy habits accounting for about 54%1 of known contributions to heart disease. Behavioral and biological interventions can reduce morbidity, disability, and death due to heart disease and stroke. They can improve quality of life and influence the behavior of policy makers in their decisions, health professionals in their practice, and people in their daily lives.However, there is a gap between the efficacy of interventions in studies and their effectiveness in practice, a gap between potential and reality, intention and action, and information and behavior. This gap illustrates the urgent need to more fully integrate the social and behavioral sciences with the biomedical sciences. Three questions arise: Despite extensive studies of strategies to prevent and treat risk factors for heart disease and stroke, current evidence documents …
