Epidemiologists respond to the information needs of health professionals. Although medical professionals are routine users of epidemiologic information, use within medical specialties varies remarkably. To explore the variation in use of epidemiologic information across clinical medical specialties, the authors examined the scientific literature by analyzing patterns of citation of specific journal articles to and by the American Journal of Epidemiology (AJE). A total of 178,396 journal citations to and 126,478 citations by AJE were made from 1983 through 1999; citations were classified according to the subject category of the referencing or referenced journal. Clinical medical journals accounted for 50.6% of all citations combined (both referenced to and referenced by AJE); general/internal medicine (17.9%), cancer (10.4%), and cardiovascular (4.9%) journals had the highest number of citations. Few citations to and by AJE were found in publications specializing in dermatology, gastroenterology, orthopedics, allergy, anesthesiology, surgery, rheumatology, and other areas. Trend patterns of citations between clinical and epidemiologic literature indicated that citations to the fields of cardiovascular disease and cancer are increasing, whereas citations regarding pediatrics have remained stable. This analysis suggests an increasing interchange of information between epidemiologists and clinicians specializing in certain fields, uncovering potential research opportunities for epidemiologists.
流行病学家回应卫生专业人员的信息需求。尽管医学专业人员是流行病学信息的常规使用者，但医学各专科对信息的使用差异显著。为探究临床各医学专科在流行病学信息使用上的差异，作者通过分析《美国流行病学杂志》（AJE）对特定期刊文章的引用模式以及被引用模式，对科学文献进行了研究。1983年至1999年期间，AJE共被引用178,396次，同时AJE引用其他期刊126,478次；引用按照引用期刊或被引用期刊的主题类别进行分类。临床医学期刊占所有引用（包括被AJE引用和AJE引用其他期刊）总和的50.6%；普通/内科（17.9%）、癌症（10.4%）和心血管（4.9%）期刊的引用次数最多。在皮肤病学、胃肠病学、骨科、过敏、麻醉学、外科、风湿病学及其他领域的专业出版物中，AJE被引用和引用其他期刊的次数很少。临床文献与流行病学文献之间的引用趋势模式表明，心血管疾病和癌症领域的引用次数在增加，而儿科方面的引用保持稳定。该分析表明，流行病学家与某些特定领域的临床医生之间的信息交流日益增加，为流行病学家揭示了潜在的研究机会。
