Relying on therapeutic interventions to address health problems after they occur has proven costly and does not address the need to reduce the number of youth who develop these health problems. Primary care physicians have an important role to play in promoting adolescent health through a strategy of providing health guidance to adolescents and parents, screening, and promoting immunizations. Reducing the health risk behaviors of adolescents is a challenge that is best accomplished with the support of other preventive initiatives. Clinical preventive services should complement and reinforce preventive efforts in schools (i.e., comprehensive school health programs) and communities (i.e., mass media campaigns and health regulations). GAPS recommendations developed by the AMA and recommendations from other groups provide a model for organizing the content and delivery of comprehensive preventive services for adolescents. Physicians and other primary care health providers may use these recommendations to expand the quantity and quality of preventive services they offer to adolescents. Additional information about preventive services and GAPS, including a complete list of the recommendations, dates for future GAPS training, a description of the materials developed to help implement preventive services, other national efforts in adolescent preventive services, and current articles in scientific literature, can be reviewed on the AMA web site (http:/(/)www.AMA-Assn.Org/Adolhlth/Adolhlth+ ++.htm).
