MANY United States families live in .~.~d~' United States families live in the suburbs of central cities, hoping to find healthier, safer and more advantageous surroundings for their children. How well do their adolescent youngsters fare in suburbia?From the medical viewpoint there is a great dearth of information on this score, partly due to the fact that young people 13 to 20 years of age are a particularly difficult group to reach; and partly because professional interest, time and resources for conducting the necessary studies are severely limited in suburban communities.One phenomenon of the current decade is that local hospital emergency rooms in towns, villages and cities across the country are experiencing an unprecedented and disproportionate increase in patient visits, reflecting changes in local patterns of medical care.With an immediate treatment service available around the clock, the emergency rooms are increasingly becoming major medical resources to the whole community. 1 Our study of 1,000 urban adolescents who came to the emergency unit of a neighborhood in New York City showed tl'leu difficulties were always acute, the inherent and crisesfocused needs of this age and revealing characteristics and problems specific to the neighborhoods in which they lived .2 These observations suggested that informative medical and health information about suburban adolescents might be gathered in a similar way, using the records of the. emergency room of a suburban community hospital. Here is a report on the findings of this study, with comments on how the insights obtained may be used in promoting preventive efforts locally and elsewhere.
