Electronic cigarettes are at the center of a public health policy debate which leverages scientific publications. This study characterizes e-cigarette publication trends over the past 15 years via a bibliometric analysis. Scopus was searched for "electronic cigarette", "e-cig", "e-cigarette", "vape", "vaping", "juul", or "electronic nicotine delivery system" between 2003⁻2018. Data included Hirsch index, document type and frequency, and publications by institution, journal, and country. VOSviewer was used to visualize authorship network maps. A total of 4490 e-cigarette publications were identified, most (62.8%) being articles. After 2009, the annual growth rate for e-cigarette publications was the largest in 2014. The annual growth rate was nearly flat in 2017 but increased in 2018. The U.S. produced 51.6% of publications. Annual National Institutes of Health NIH funding for tobacco research mapped closely with the annual volume of e-cigarette publications. Author network analyses illustrated investigator collaborative patterns. The frequency of e-cigarette publications increased significantly in the past decade. A strong relationship of NIH funding for tobacco research and e-cigarette publications demonstrates the importance of e-cigarettes in tobacco research.
电子烟是公共卫生政策辩论的核心，这场辩论利用了科学出版物。本研究通过文献计量分析来描述过去 15 年电子烟的出版趋势。在 2003 年至 2018 年间，我们在 Scopus 上以“electronic cigarette”“e-cig”“e-cigarette”“vape”“vaping”“juul”或“electronic nicotine delivery system”为检索词进行了检索。数据包括 Hirsch 指数、文献类型和频率，以及机构、期刊和国家的出版物。使用 VOSviewer 可视化作者网络地图。共确定了 4490 篇电子烟出版物，其中大多数（62.8%）是文章。2009 年以后，电子烟出版物的年增长率在 2014 年最大。2017 年的年增长率几乎持平，但在 2018 年有所增加。美国生产了 51.6%的出版物。美国国立卫生研究院（NIH）烟草研究的年度资助与电子烟出版物的年度数量密切相关。作者网络分析说明了研究人员的合作模式。过去十年中，电子烟出版物的频率显著增加。NIH 对烟草研究的资助与电子烟出版物之间的密切关系表明了电子烟在烟草研究中的重要性。
