摘　　要：目的应用文献计量学方法对比分析全球以"循证"冠名的一次文献期刊2009年发表文献情况,为以后循证研究、期刊建设等提供参考。方法电子检索全球以"循证"冠名的一次文献期刊,通过期刊网站及引文数据库收集其影响因子、文献点击、下载及被引频次,计算并比较分析其即年指标、篇均下载、被引频次、下载及被引用文献的分布情况。结果共检出5种英文和4种中文以"循证"冠名的期刊,其中2种英文无法收集相关数据,故最终纳入7种期刊。①被引频次:《Evidence-Based Complementary and Alternative Medicine》和《Worldviewson Evidence-Based Nursing》被SCI收录,影响因子均超过1,分列其同类期刊的第5位和第13位,且即年指标约为中文期刊的7倍(平均约0.2vs0.03)。中文期刊中《中国循证儿科杂志》影响因子最高(0.946),列同类期刊的第23位,《中国循证医学杂志》即年指标最高(0.07)。②下载频次:《Journal of Evidence-Based Medicine》的数据库篇均下载频次远高于其他期刊(约72vs23);而免费提供全文下载的《中国循证医学杂志》和《中国循证儿科杂志》篇均下载频次约为前者的5～6倍;③载文量:载文量最多的《中国循证医学杂志》的影响因子为0.685,其篇均下载频次和即年指标居中文期刊之首,而影响因子最高的2种英文期刊载文量最少,提示载文量与期刊影响因子并无直接联系。结论"循证"冠名的英文期刊影响力高于中文期刊;建有免费下载网站的《中国循证医学杂志》和《中国循证儿科杂志》的影响力高于其它中文期刊;提示期刊组稿应从读者需求出发,采用在线出版、开放存取等形式来提高期刊影响力。Objective To compare articles published in global primary journals titled （evidence-based） via bibliometric analysis in order to provide suggestion for evidence-based research and development of related journals. Methods We searched electronic databases to retrieve global primary journals titled （evidence-based）, and collected their impact factors, article click, download and citation frequency through the journal＇s website and related citation databases. Results Three English and 4 Chinese primary journals titled （evidence-based） met the inclusion criteria. （1） Citation frequency： Evidence-Based Complementary Alternative Medicine and Worldviews on Evidence-Based Nursing were indexed by SCI with impact factor over 1 （5th and 13th in relevant subject category）, and their immediacy index was about 7 times as much as that of Chinese journals （0.2 vs 0.03）. Chinese Journal of Evidence-Based Pediatrics （CJEBP） had the highest impact factor among 4 Chinese journals （0.946, 23rd in the relevant subject category）, while Chinese Journal of Evidence-Based Medicine had the highest immediacy index with 0.07; （2） Download frequency： Journal of Evidence-based Medicine （JEBM） had the highest download frequency per article in database （72 vs 23）, but the website download frequencies per article of CJEBM and CJEBP were about 5 to 6 times as much as that of database; （3） Number of articles published： Two English journals published the fewest articles but with the highest impact factors. Chinese Journal of Evidence-Based Medicine had the 2nd highest impact factor although published the most articles, as well as the highest download frequency and immediacy index among the 4 Chinese journals. It suggested that there was no direct relationship between the number of the published articles and the impact factor of a journal. Conclusion The impact of English journals is better than that of Chinese journals. CJEBM and CJEBP are the top 2 ones among the Chinese journals with open acce
