Changes in the leading causes of adolescent morbidity and mortality have been well documented in the scientific and consumer literature. Evidence suggests that significant sources of contemporary health problems are related to personal behavior and, therefore, are potentially preventable. It also seems that consistent health promotion messages from schools, parents, the community, and health professionals may be effective in reducing health risk behavior. Spurred on by the costs, both economic and personal, incurred from treating causes of morbidity and mortality a wide coalition of health providers, federal agencies, organized medicine groups, and purchasers of health care have promoted a shift in medical care toward prevention. The purpose of this article is to review the rationale for clinical preventive services for adolescents as a strategy for reducing morbidity and mortality and then to describe a strategy for integrating these services into routine medical care.
