Reddit is a popular social media platform for sharing information about vaping. Little is known about the types of external resources that Reddit users in vaping communities share and engage with.
We analysed 2315 posts containing uniform resource locators (URLs) published to vaping communities on Reddit between November 2021 and October 2022. We coded URLs into eight mutually exclusive domain types. A mixed-effects Poisson regression model examined whether domain type was associated with user engagement (ie, number of unique commenters).
Posts contained links to social media (35%), image hosting (31%), vaping-related commerce (19%), eJuice (12%), general vaping (6%), news (2%) and research (1%) URL domains. There were 237 unique vaping-related commerce domains (eg, ziipstock.com). The average number of commenters per post was 5.43 (SD=8.04). The rate of commenters was higher for posts sharing research (adjusted rate ratio (aRR) 1.74, 95% CI 1.28 to 2.36) and news (aRR 1.56, 95% CI 1.02 to 2.38) domains compared with vape-related commerce domains.
Reddit users in vaping communities share and interact with a variety of external resources. The >200 different vaping-related commerce domains in our sample speak to the breadth and availability of websites that Reddit users (perhaps even those underage) may be using to browse and purchase vaping devices.
Reddit是一个流行的社交媒体平台，用于分享有关电子烟的信息。对于电子烟社区中Reddit用户分享和参与的外部资源类型，我们知之甚少。
我们分析了2021年11月至2022年10月期间发布在Reddit上电子烟社区的2315条包含统一资源定位符（URL）的帖子。我们将URL编码为八种相互排斥的域名类型。一个混合效应泊松回归模型检验了域名类型是否与用户参与度（即独特评论者的数量）相关。
帖子包含指向社交媒体（35%）、图像托管（31%）、电子烟相关商业（19%）、电子烟液（12%）、一般电子烟（6%）、新闻（2%）和研究（1%）URL域名的链接。有237个独特的电子烟相关商业域名（如ziipstock.com）。每个帖子的评论者平均数量为5.43（标准差=8.04）。与电子烟相关商业域名相比，分享研究（调整率比（aRR）1.74，95%置信区间1.28至2.36）和新闻（aRR 1.56，95%置信区间1.02至2.38）域名的帖子的评论者率更高。
电子烟社区中的Reddit用户分享并与各种外部资源进行互动。我们样本中超过200个不同的电子烟相关商业域名表明，Reddit用户（甚至可能包括未成年人）可能用于浏览和购买电子烟设备的网站的广度和可用性。
