This volume contains 21 articles on aspects held to be important for delivering comprehensive health care to young adults who are at higher than average risk levels for a number of health and health-related problems; choice of topics for the articles is based on experience gained in directing the health program for the Job Corps. Most of the articles are reworked presentations from two colloquia held in February 1972. A few of the articles describe new approaches used by Job Corps to address the health-related problems that can prevent disadvantaged young adults from achieving their self-defined goals. Others deal with common medical problems such as hepatitis, skin diseases, nutritional deficiencies, obesity, and sickle cell disease and traits. Yet others focus on sexuality, venereal disease, and family planning. The last group of articles covers mental health and drugs--dealing with mental health emergencies, aggressive behavior, tobacco, drug addiction, and helping the drug-abusing enrollee in Job Corps. A list of materials produced by Job Corps health staff, including films, brochures, reports, and major publications available for distribution, concludes the monograph. (RJ)
