电子烟研究进展——2010-2022 年的文献计量分析。

INTRODUCTION: Electronic cigarettes have been widely used all over the world. It is not clear what the advantages and disadvantages of a novelty in daily life are that is attracting increasing attention. Up to now, no bibliometric studies on e-cigarettes have been published in databases. Therefore, we are willing to explore directions and research hotspots in this emerging field by using bibliometrics to analyze research areas, publishing countries and institutions, high-output authors, and future trends of e-cigarettes in recent years. Compared with the traditional review, the bibliometric study can provide some information on core journals, articles, researchers, institutions, and countries concentrating on this topic to guide experimentation strategies and funding decisions. METHODS: A bibliometric analysis was performed by CiteSpace and VOSviewer up to April 2022 in the core collection of Web of Science. HistCite, VOSviewer, CiteSpace, and the R-based Bibliometrix 4.1.0 packages were used to analyze literature information, including year, journal, country, institute, author, keywords, and co-cited references. RESULTS: Research related to e-cigarettes has proliferated since its inception around 2010. A total of 2,302 studies were published in 689 journals by our search method. Nicotine and tobacco research was the most published journal. The most prolific country was the United States, while the most influential institution was Virginia Commonwealth University. Eight of the top ten authors were from the United States. Oxidative stress, high school students, smoking cessation, delivery, behavioral economics, and exposure were the top topics. CONCLUSIONS: As an emerging social phenomenon, research on e-cigarettes has increased significantly over the past decade, particularly from 2015 to 2020. The top three core journals are Nicotine and Tobacco Research, the International Journal of Environmental Research, and Public Health. Eisenberg-Thomas had published numerous articles on e-cigarettes that had been co-cited in many papers. Oxidative stress, high school students, and smoking cessation are the top three areas of e-cigarette-related research, which were also important areas for further investigation.

简介：电子烟在全球范围内得到了广泛的应用。目前尚不清楚日常生活中这种日益受到关注的新奇事物有哪些优点和缺点。到目前为止，还没有在数据库中发表过关于电子烟的文献计量学研究。因此，我们希望通过文献计量学分析来探索近年来电子烟这一新兴领域的研究方向和热点，分析研究领域、出版国家和机构、高产作者以及电子烟的未来趋势。与传统综述相比，文献计量学研究可以为核心期刊、文章、研究人员、机构和国家提供一些关于该主题的信息，以指导实验策略和资金决策。

方法：我们对截至 2022 年 4 月在 Web of Science 核心集收录的电子烟相关文献进行了文献计量学分析，使用 HistCite、VOSviewer、CiteSpace 和基于 R 的 Bibliometrix 4.1.0 软件包分析文献信息，包括年份、期刊、国家、机构、作者、关键词和共引参考文献。

结果：电子烟相关研究自 2010 年左右开始兴起，通过我们的检索方法共检索到 2302 篇发表在 689 种期刊上的研究。发表论文数量最多的期刊是《尼古丁与烟草研究》，发表论文数量最多的国家是美国，最有影响力的机构是弗吉尼亚联邦大学。排名前十的作者中有八位来自美国。氧化应激、高中生、戒烟、传递、行为经济学和暴露是排名前 10 的主题。

结论：作为一种新兴的社会现象，过去十年中，电子烟的研究显著增加，尤其是 2015 年至 2020 年。排名前三的核心期刊是《尼古丁与烟草研究》《国际环境研究与公共卫生杂志》和《公共卫生》。Eisenberg-Thomas 发表了多篇关于电子烟的文章，这些文章在许多论文中被共同引用。氧化应激、高中生和戒烟是电子烟相关研究的前三个领域，也是进一步研究的重要领域。
