Research on electronic cigarettes is an emerging field, with the number of articles in this field noted to have grown exponentially over recent years. We used a bibliometric analysis method (co-word analysis) to analyze the emerging trends and research hotspots in this field.
Publication data on electronic cigarettes from 2010 to 2018 were retrieved and downloaded from the PubMed database. Theme trends and knowledge structures were analyzed on the relevant research fields of electronic cigarettes by using a biclustering analysis, strategic diagram analysis, and social network analysis methods. Research hotspots were extracted and compared from three periods.
Core topics that have continuously develop between the years 2010 and 2018 include: tobacco use cessation devices; tobacco products; tobacco use cessation devices/adverse effects; smoking prevention and adverse effects; electronic nicotine delivery systems/economics; and public health. Some currently undeveloped topics that could be considered as new future research directions include: tobacco use disorder/therapy; tobacco use disorder/epidemiology; students/psychology; students/statistics and numerical data; adolescent behavior/psychology; nicotine/toxicity; nicotinic agonists/administration and dosage; and electronic nicotine delivery systems/legislation and jurisprudence.
Results suggest that some currently immature topics in strategic coordinates and emerging hotspots in social network graphs can be used as future research directions.
电子烟研究是一个新兴领域，近年来该领域的文章数量呈指数级增长。我们采用文献计量分析方法（共词分析）来分析该领域的新兴趋势和研究热点。
从PubMed数据库中检索并下载2010年至2018年关于电子烟的发表数据。运用双聚类分析、战略图分析和社会网络分析方法，对电子烟相关研究领域的主题趋势和知识结构进行分析。从三个时期提取并比较研究热点。
2010年至2018年间持续发展的核心主题包括：戒烟装置；烟草制品；戒烟装置/不良反应；预防吸烟和不良反应；电子尼古丁传送系统/经济学；以及公共卫生。一些目前尚未充分研究、可被视为未来新研究方向的主题包括：烟草使用障碍/治疗；烟草使用障碍/流行病学；学生/心理学；学生/统计与数值数据；青少年行为/心理学；尼古丁/毒性；烟碱激动剂/给药与剂量；以及电子尼古丁传送系统/立法与法理学。
结果表明，战略坐标中一些目前尚未成熟的主题以及社会网络图中的新兴热点可作为未来的研究方向。
