Abstract

BACKGROUND

There is an established trend towards an increasing number of authors per article in prestigious journals for medicine and health sciences. It is uncertain whether a similar trend occurs to the same extent in journals for specific medical specialties.

METHODS

Journals focusing on occupational medicine were selected for analysis with regard to single or multiple-authorship per peer-reviewed paper. Data were collected from PubMed for publications between 1970 and 2007. These were analysed to calculate the average number of authors per multiple-author article per year and the percentage of single-author articles per year. The slope and average of these journals were then compared with that of previously studied non-occupational medicine journals.

RESULTS

The results confirm a trend towards a linear increase in the average number of authors per article and a linear decrease in the percentage of single-author articles. The slope for the average number of authors for multiple-author articles was significantly higher in the Journal of Occupational and Environmental Medicine than in the other occupational medicine journals. Computational analysis of all articles published showed that Occupational Medicine (Oxford) had a significantly higher percentage of single-author articles than the other occupational medicine journals as well as major journals previously studied.

CONCLUSION

The same trend towards multiple authorship can be observed in medical specialty journals as in major journals for medicine and health sciences. There is a direct relationship between occupational journals with higher impact factors and a higher average number of authors per article in those journals.

摘要

背景

在医学和健康科学领域的知名期刊中，每篇文章的作者数量呈明显增多趋势。但在针对特定医学专科的期刊中，这种趋势是否同样显著还不确定。

方法

选取职业医学期刊，分析其每篇同行评审论文的单作者或多作者情况。1970 年至 2007 年，从 PubMed 收集数据。计算每年多作者文章的平均作者数和每年单作者文章的比例。然后将这些期刊的斜率和平均值与之前研究的非职业医学期刊进行比较。

结果

结果证实了文章作者数量呈线性增加、单作者文章比例呈线性下降的趋势。多作者文章的平均作者数斜率在《职业与环境医学杂志》（Journal of Occupational and Environmental Medicine）中显著高于其他职业医学期刊。对所有发表文章的计算分析表明，《职业医学（牛津）》（Occupational Medicine (Oxford)）的单作者文章比例显著高于其他职业医学期刊以及之前研究的主要期刊。

结论

在医学专科期刊中也可以观察到与医学和健康科学主要期刊相同的多作者趋势。影响因子较高的职业期刊与这些期刊中每篇文章的平均作者数之间存在直接关系。
