There is no consensus if electronic nicotine delivery systems (ENDS) should be used to reduce harm among the smoking population. Physicians, who represent a trusted source of health communication, are exposed to a range of often conflicting ENDS information and this information may be relayed to patients looking to quit smoking. Previous studies have examined ENDS content of various sources of media but there is a lack of knowledge about ENDS content in medical journals. We analyzed 421 ENDS publications printed between 2012 and 2018 from PubMed's Core Clinical Journal list. Publications were analyzed based on publication type, journal type, study design, geographic focus, theme, terminology, outcomes, and positive/negative statements. The number of ENDS publications grew since 2012, and peaked in 2015. Across all years, negative statements about ENDS outnumbered positive statements, though this difference decreased over time. Over time, negative statements about "toxins and carcinogens" were made less frequently, while negative statements about "gateway effects" and "youth appeal" became more prevalent. UK journals had fewer negative statements relative to US journals. Only 12.6% of publications included guidance for healthcare professionals about ENDS. As published ENDS topics change over time, physicians' communications with patients may be impacted.
目前，对于是否应该使用电子尼古丁传送系统（ENDS）来减少吸烟人群的危害，尚无定论。医生作为健康传播的可靠信息来源，接触到的 ENDS 信息范围广泛，且这些信息可能会转达给希望戒烟的患者。先前的研究已经考察了各种媒体来源的 ENDS 内容，但对于医学期刊中的 ENDS 内容却知之甚少。我们分析了 2012 年至 2018 年期间来自 PubMed 核心临床期刊列表的 421 篇 ENDS 出版物。这些出版物是根据出版类型、期刊类型、研究设计、地理重点、主题、术语、结果以及正面/负面陈述进行分析的。自 2012 年以来，ENDS 出版物的数量有所增加，并在 2015 年达到峰值。在所有年份中，关于 ENDS 的负面陈述多于正面陈述，但这种差异随着时间的推移而减少。随着时间的推移，关于“毒素和致癌物质”的负面陈述变得不那么频繁，而关于“入门效应”和“对年轻人的吸引力”的负面陈述则变得更为普遍。英国期刊发表的负面陈述相对较少，而美国期刊发表的负面陈述相对较多。只有 12.6%的出版物包含有关 ENDS 的医疗保健专业人员指南。随着已发表的 ENDS 主题随时间发生变化，医生与患者的沟通可能会受到影响。
