Public health's promise for the future: 1989 presidential address.

Public health's promise for the future is inextricably related to efforts which maximize human potential and which realize the world's interdependence. Public health challenges are not only constant and complex but frequently surrounded by political activities. In this environment, the public health enterprise has been enhanced by the Institute of Medicine, National Academy of Sciences' report on The Future of Public Health and the assessment framework it provides. Risk reduction through preventive and health promotion activities is the primary focus of public health, but facilitation is often dependent upon society's understanding and willingness-to-pay for such services. The effectiveness of public health is related to an ability to coordinate public and private efforts at national, state, and local levels. Also in this environment, public health is empowered through its multidisciplinary approach. However, epidemiology provides a unifying framework for the collective public health effort. Based on the use of epidemiology, public health is empowered to make the argument for a national health program and to support the concept of health as a determinant of life options. Public health's promise for the future can be fulfilled by continuing to increase its scientific base for decision-making, by self-examination and correction, by advocating and promoting self-examination and correction, by advocating and promoting social justice and by promoting firm partnerships with the public.
