BACKGROUND
Research in the fields of Preventive Medicine, Occupational/Environmental Medicine, Epidemiology and Public Health play an important role in the advancement of knowledge. In order to map the research production around the world we performed a bibliometric analysis in the above fields.
METHODS
All articles published by different world regions in the above mentioned scientific fields and cited in the Journal Citation Reports (JCR) database of the Institute for Scientific Information (ISI) during the period 1995 and 2003, were evaluated. The research production of different world regions was adjusted for: a) the gross domestic product in 1995 US dollars, and b) the population size of each region.
RESULTS
A total of 48,861 articles were retrieved and categorized. The USA led the research production in all three subcategories. The percentage of articles published by USA researchers was 43%, 44% and 61% in the Preventive Medicine, Epidemiology, and Public Health subcategories, respectively. Canada and Western Europe shared the second position in the first two subcategories, while Oceania researchers ranked second in the field of Public Health.
CONCLUSION
USA researchers maintain a leadership position in the production of scientific articles in the fields of Preventive Medicine, Occupational/Environmental Medicine and Epidemiology, at a level similar to other scientific disciplines, while USA contribution to science in the field of Public Health is by all means outstanding. Less developed regions would need to support their researchers in the above fields in order to improve scientific production and advancement of knowledge in their countries.
背景
预防医学、职业/环境医学、流行病学和公共卫生领域的研究在知识进步方面发挥着重要作用。为了梳理全球范围内的研究成果，我们对上述领域进行了文献计量分析。
方法
对1995年至2003年期间不同世界地区在上述科学领域发表并被科学信息研究所（ISI）的《期刊引证报告》（JCR）数据库收录的所有文章进行评估。对不同世界地区的研究成果进行了如下调整：a）以1995年美元计算的国内生产总值，以及b）每个地区的人口规模。
结果
共检索并分类了48,861篇文章。美国在所有三个子类别中研究成果领先。美国研究人员发表的文章在预防医学、流行病学和公共卫生子类别中的占比分别为43%、44%和61%。加拿大和西欧在前两个子类别中并列第二，而大洋洲研究人员在公共卫生领域排名第二。
结论
美国研究人员在预防医学、职业/环境医学和流行病学领域的科学文章产出方面保持领先地位，与其他科学学科的水平相当，而美国在公共卫生领域对科学的贡献无疑是杰出的。欠发达地区需要支持其在上述领域的研究人员，以提高本国的科研产出和知识进步。
