作为世界上最受欢迎的视频分享网站，YouTube有潜力触及并影响庞大的受众。这项研究旨在通过评估电子烟视频的数量、描述和覆盖范围，系统地了解人们在YouTube上接触到了哪些电子烟信息。研究人员根据相关度和浏览量确定了YouTube上搜索结果排名前20位的下列搜索词：“电子烟”、“正在吸烟的电子烟”、“正在吸烟的电子烟”。196个独特的视频样本被编码为整体肖像和流派。记录了电子烟视频中涉及的主要主题，并记录了视频统计数据和观众人口统计信息。在这196个独特的视频中，94%(n = 185)支持电子烟，4%(n = 8)持中立态度，而只有2%(n = 3)支持电子烟。排名前三位的视频类型分别是广告、用户分享和产品评论。84.3%的专业视频包含购买电子烟的网络链接。71.4%的专业视频声称电子烟比传统香烟更健康。观众主要来自美国、英国和加拿大，“支持”的电子烟视频被观看得更频繁，评分也比“反对”的视频好得多。YouTube上绝大多数关于电子烟的信息都在宣传电子烟的使用，并将电子烟的使用描述为社会可以接受的。开展适当的健康运动，告知电子烟消费者与使用电子烟有关的潜在危害，这一点至关重要。
As the most popular video sharing website in the world, YouTube has the potential to reach and influence a huge audience. This study aims to gain a systematic understanding of what e-cigarette messages people are being exposed to on YouTube by assessing the quantity, portrayal and reach of e-cigarette videos. Researchers identified the top 20 search results on YouTube by relevance and view count for the following search terms: “electronic cigarettes”, “e-cigarettes”, “ecigarettes”, “ecigs”, “smoking electronic cigarettes”, “smoking e-cigarettes”, “smoking ecigarettes”, “smoking ecigs”. A sample of 196 unique videos was coded for overall portrayal and genre. Main topics covered in e-cigarette videos were recorded and video statistics and viewer demographic information were documented. Among the 196 unique videos, 94% (n = 185) were “pro” to e-cigarettes and 4% (n = 8) were neutral, while there were only 2% (n = 3) that were “anti” to e-cigarettes. The top 3 most prevalent genres of videos were advertisement, user sharing and product review. 84.3% of “pro” videos contained Web links for e-cigarette purchase. 71.4% of “pro” videos claimed that e-cigarettes were healthier than conventional cigarettes. Audience was primarily from the United States, the United Kingdom and Canada and “pro” e-cigarette videos were watched more frequently and rated much more favorably than “anti” ones. The vast majority of information on YouTube about e-cigarettes promoted their use and depicted the use of e-cigarettes as socially acceptable. It is critical to develop appropriate health campaigns to inform e-cigarette consumers of potential harms associated with e-cigarette use.
