Increased attention to adolescent health and well-being has been stimulated by rising mortality rates and high morbidity rates among adolescents. Several national inquiries have found that the responses of medical and other service systems do not adequately meet the health-related needs of adolescents and that a different approach, involving collaboration among the various service sectors that impinge on adolescents' lives, is needed. The school is being viewed as the hub around which these services can most easily and effectively be coordinated and delivered to teens. This school-linked, multi-service model has been implemented in a number of states. Initiatives in California, Florida, Kentucky, Michigan, New Jersey, New York, and Oregon are outlined in this report. Highlights of a seminar that focused on the many interrelated health problems of adolescents open the report. In addition, the report reviews research related to adolescents' health status; reviews the influence of changing family trends and the role of parents in promoting well-being; discusses the shortcomings of the current health care system with regard to adolescent health needs; discusses how to make services "family-friendly"; describes the background, history, and key components of school-linked, multi-service demonstration programs; and identifies issues about school-linked centers that need further study.
