Background Previous studies have demonstrated that the frequency with which a publication is cited varies greatly. Our objective was to determine whether author, country, journal, or topic were associated with the number of times an epidemiological publication is cited. Methods We used outcome-based sampling and investigated one public health issue – child injury prevention, and one clinical topic – coronary artery disease (CAD) prevention. Using the Institute for Scientific Information's (ISI) Web of Science? databases, we limited searches to full articles involving humans published in English between 1998 and 2004. We calculated the citation rate and, after frequency-matching on year of publication, selected the 36 most frequently cited and 36 least frequently cited articles per year, for a total of 252 highly-cited and 252 infrequently-cited articles per topic area (child injury prevention and CAD prevention). Results Highly-cited articles in both CAD and child injury prevention were more likely to be published in medium or high impact journals or in journals with medium or high circulations. They were also more likely to be published by authors from U.S. institutions. Among articles examining CAD prevention, the highly-cited articles often involved risk factors, and the association between topics and frequency of citation persisted after adjusting for impact factor. Among articles addressing child injury prevention, topic was not statistically associated with citation. Conclusion Journal and country appear to be the factors most strongly associated with frequency of citation. In particular, highly-cited articles are predominantly published in high-impact, high-circulation journals. The factors, however, differ somewhat depending on the area of research the journals represent. Among CAD prevention articles, for example, topic is also an important predictor of citation whereas the same is not true for articles addressing injury prevention.

机译：背景技术先前的研究表明，引用出版物的频率差异很大。我们的目标是确定作者，国家，期刊或主题是否与流行病学出版物被引用的次数相关。方法我们采用基于结果的抽样方法，调查了一项公共健康问题-预防儿童伤害，以及一项临床主题-预防冠状动脉疾病（CAD）。使用科学信息研究所（ISI）的Web of Science ？数据库，我们将搜索范围限制为1998年至2004年之间以英文发表的涉及人类的全文。引用率，并在与发表年份匹配后，每年选择36篇最常被引用的文章和36篇最不常被引用的文章，每个主题区域总共252篇被高引用和252篇不被频繁引用的文章（预防儿童伤害和CAD预防）。结果在CAD和儿童伤害预防方面被高引用的文章更有可能在中，高影响力期刊或中，高流通量期刊上发表。它们也更有可能由美国机构的作者出版。在检查CAD预防的文章中，被高引用的文章通常涉及风险因素，并且在调整影响因素后，主题与引用频率之间的关联仍然存在。在有关预防儿童伤害的文章中，主题与引文在统计上没有关联。结论期刊和国家/地区似乎是与被引频率最相关的因素。特别是，高被引用的文章主要发表在高影响力，高发行量的期刊上。但是，这些因素因期刊所代表的研究领域而有所不同。例如，在CAD预防文章中，主题也是引文的重要预测指标，而涉及伤害预防的文章却并非如此。摘要我们的目的是确定作者，国家，期刊或主题是否与流行病学出版物被引用的次数相关。我们使用了基于结果的抽样方法，并调查了一项公共健康问题，儿童伤害预防和一项临床主题-冠状动脉疾病（CAD）预防。使用科学信息研究所（ISI）的Web of Science ？数据库，我们将搜索范围限制为1998年至2004年之间以英文发表的涉及人类的全文。引用率，并在与发表年份匹配后，每年选择36篇最常被引用的文章和36篇最不常被引用的文章，每个主题区域总共252篇被高引用和252篇不被频繁引用的文章（预防儿童伤害和CAD预防）。在CAD和儿童伤害预防方面被高引用的文章更有可能在中，高影响力期刊或中，高流通量期刊上发表。它们也更有可能由美国机构的作者出版。在检查CAD预防的文章中，被高引用的文章通常涉及风险因素，并且在调整影响因素后，主题与引用频率之间的关联仍然存在。在有关预防儿童伤害的文章中，主题与引文在统计上没有关联。
