OBJECTIVES
To study the role assumed by epidemiology in occupational health literature and characterise its change over the years.
METHODS
A bibliometric study was conducted with a MEDLINE search to evaluate 9024 articles published in eight representative occupational health journals for the period 1980-93. Articles related to epidemiology were found by descriptors indexed in the articles and their numbers and proportions among all published articles was tabulated for the study period.
RESULTS
The proportion of source items indexed by epidemiology as a descriptor increased over threefold from 7.9% (42/534) in 1980 to over 25% after 1990. Epidemiology was indexed most frequently as a subheading associated with other descriptors-for example, occupational diseases-epidemiology. Cohort studies had the largest increase in the descriptors that indicated epidemiological type of studies during the period studied.
CONCLUSION
Epidemiology is assuming increasing importance in occupational health literature. This was shown quantitatively and qualitatively by the use of descriptors in the MEDLINE database.
目的
研究流行病学在职业健康文献中所起的作用，并描述其多年来的变化特征。
方法
进行了一项文献计量学研究，通过医学文献数据库（MEDLINE）检索来评估1980 - 1993年期间在八本代表性职业健康期刊上发表的9024篇文章。通过文章中索引的描述符找出与流行病学相关的文章，并将其在整个研究期间所有发表文章中的数量和比例制成表格。
结果
以流行病学作为描述符索引的源文章比例从1980年的7.9%（42/534）增加了三倍多，到1990年后超过25%。流行病学作为与其他描述符相关的副标题被索引的频率最高，例如职业疾病 - 流行病学。在所研究的期间，队列研究在表明流行病学研究类型的描述符方面增加幅度最大。
结论
流行病学在职业健康文献中日益重要。通过医学文献数据库（MEDLINE）中描述符的使用，从定量和定性方面都证明了这一点。
