以中国知网和万方数据两大数据库期刊导航系统中预防医学与卫生学类的全部73本学术期刊为研究对象,通过查阅各期刊印刷版、《中国学术期刊综合引证报告2008版》及中国知网中国学术期刊评价统计分析平台采集相关数据.分析国内公共卫生与预防医学学术期刊的整体水平及发展特征与趋势,结果发现,该期刊群数目增长最快的时期是20世纪70—80年代,增长率超过200%;期刊主办地主要集中在华北地区,占43.8%,其中北京占总数的27.4%;截至2010年,出版周期双月刊占49.3%,旬刊和半月刊占5.47%;有23%的期刊第一主办单位为中华预防医学会;印刷质量普遍较好,特色突出;有独立自主网站的占24.3%,依托公共数据库或主办单位网站占30.1%,尚有38.4%的期刊没有提供公共网址;平均发表时滞为178d;69%的期刊对于读者咨询在24h内回复.该期刊群在2007年影响力指标的平均水平为：总发文量259篇,影响因子0.392,总被引频次742次,即年指标0.043,被引半衰期4.2a.2001—2007年间,4种主要文献计量学指标(影响因子、即年指标、被引半衰期、平均下载总量)均呈增长趋势.结果提示,中国预防医学类学术期刊从20世纪50年代开始陆续创刊以来,期刊群数目逐渐增多,出版质量、印刷质量、服务质量均不断提高;文献计量学指标(被引指标和来源指标)的平均水平与全国期刊总体平均水平接近,但各刊发展并不均衡,指标差别明显;网络信息化和开放存取程度相对低于国内科技期刊的总体水平,尚有很大的发展空间.

To analyze the present state of academic periodicals on public health and preventive medicine in China, 73 academic periodicals in the area of preventive medicine and public health were selected from China National Knowledge Infrastructure (CNKI) and Wanfang Data Knowledge Platform. The major sources of data come from the periodicals, CNKI, China Academic Periodicals Web, China Citation Database, China Academic Periodicals Analysis Platform, and Chinese Academic Journals Comprehensive Citation Report 2008 (Beijing: Science Publisher). The 1980s is a period that saw the fastest growth in the number of periodicals, with growth rate over 200%. 43.8% of the editorial offices are located in the North China, 27.4% in Beijing. Most periodicals are published bimonthly (49.3%) while 4 are published semimonthly or once every ten days (5.47%). 23% of the periodicals are sponsored by Chinese Preventive Medicine Association (CPMA). Most of them are of good quality in printing and other features. 24.3% of them have their own websites, 30.1% uses public websites, and 38.4% do not use websites at all. The average time between the submission and the publication of a paper is 178 days, which falls short of the requirement for national scientific periodicals. Electronic service is common and effective. 69% of the periodicals respond to readers' queries within 24 hours. The average bibliometric indices of the 73 preventive medicine periodicals are as follows: the total publication number 259, the impact factor 0.392, the total citation 742, the impact factor in the same year 0.043, and the cited half-life 4.2 years. From 2001 to 2007, the 4 main indices (impact factor, impact factor in the same year, cited half-life, web download) see an upward trend. As a conclusion, Chinese preventive medicine periodicals have been improved in quantity since the 50's of the last century. The editorial, printing and service qualities have been improved. In the last decade, the average bibliometric indices (citation factor and source factor) have been improved steadily. However, the differences of the indices among journals are significant. Compared with the overall quality of Chinese scientific periodicals, the levels of network information and open database of preventive medicine periodicals lag relatively behind and need improvement.
