Abstract:

[Purposes] We try to study the factors influencing the cited frequency of scientific papers in preventive medicine systematically, so as to provide a scientific reference for the comprehensive understanding of cited frequency. [Methods] The papers published on Chinese Journal of Preventive Medicine from 2014 to 2017 were retrieved from Chinese Medical Citation Index (CMCI) and the information on these papers was recorded. The citation information of these papers by core scientific journals of China from 2014 to 2018 was obtained from the Chinese Scientific and Technical Papers and Citation Database (CSTPCD) developed by Institute of Scientific and Technical Information of China and the distribution rule of the cited frequency was summarized. Then the influencing factors (apart from academic quality) of cited frequency were analyzed with the negative binomial regression model and ordinal logistic regression model. [Findings] The 929 papers published on Chinese Journal of Preventive Medicine during 2014-2017 occupied 3564 pages, with an average of 3.84 pages per paper. The total cites of these papers was 3861 with M(P₂₅, P₇₅) of 2 (1, 5), averaging 4.15 cites per paper. The results of negative binomial regression model and ordinal logistic regression model show that papers are frequently cited if they are published early with more pages and belonged to special issue, commentaries, and the field of infectious disease epidemiology and chronic non-infectious disease epidemiology. [Conclusions] Aside from academic quality, the publishing time, pages, special issue, types, and subjects of papers tend to be the influencing factors of cited frequency. The above factors can be used as a reference for contribution soliciting to improve the influence of academic journals.

摘要：

【目的】 系统研究预防医学类科技论文被引频次的影响因素,为全面认识被引频次提供科学依据。【方法】 通过中国生物医学期刊引文数据库检索2014—2017年发表在《中华预防医学杂志》的所有文献,人工统计各文献相关信息;通过中国科技论文与引文数据库,获得由中国科学技术信息研究所提供的上述文献在2014—2018年被中国科技核心期刊引用的数据信息。分析论文被引频次的分布规律,并采用广义线性模型的负二项回归模型和多因素有序多分类Logistic回归模型分析除学术质量以外的被引频次的影响因素。【结果】 《中华预防医学杂志》2014—2017年共发文929篇,总论文版面数为3564面,篇均3.84面。论文总被引频次为3861次,被引频次的M(P₂₅,P₇₅)为2(1,5)次,篇均被引4.15次。负二项回归和多因素Logistic回归模型分析结果均显示:发表时间越早、论文版面数越多、重点号专题、述评类、传染病和慢性非传染病流行病学学科论文的被引频次较高。【结论】 除学术质量外,论文的发表时间、论文版面数、是否为重点号专题、论文类型和学科分类可能与被引频次有关联;在编辑实践中,可参考上述结果组约稿件,进一步提高期刊的学术影响力。
