ABSTRACT: PROJECT 1 (P1) Background: Social media is a ubiquitous channel of exposure to novel e-cigarette products, particularly for youth. Yet, there is little evidence characterizing e-cigarette product diversity portrayed on social media and the impact of social media exposure to products on tobacco product use. P1 aims to provide FDA with targets for regulation using social media as a platform to understand e-cigarette product diversity, and to inform regulation that benefits the ‘population as a whole’ by protecting vulnerable young non-users while also considering impact on adult smokers who have switched (or are interested in switching) to e-cigarettes. Method: Two complemen- tary studies will address two aims. Aim 1. To analyze continuously collected social media posts with e-cigarette and other tobacco product-related keywords to determine patterns of occurrences that indicate trends in product marketing, conversations about e-cigarette products, and their diverse product characteristics. To this end, Aim 1 will examine new keywords and themes that co-occur with youth-oriented posts aimed at non-tobacco-users, and health-oriented posts aimed at current smokers regarding switching to e-cigarettes. P1 tests the hypothesis that there will be postings on e-cigarette products with youth-oriented themes (i.e., about e-cigarette flavors, vape clouds, discounts, and cartoons) that tend to co-occur with one another, and that such themes will be unlikely to co-occur with postings on e-cigarette products with health-oriented themes (e.g., claims about reduced harm of e-cigarettes to self and others, or about smoking cessation). P1 also tests the hypothesis that messages with youth-oriented themes will produce more user engagement (likes) and dissemination (retweets, shares) than messages without them. Aim 2. To determine whether participation (e.g., posting, liking, sharing) in e- cigarette-related social media, especially posts that contain youth-oriented themes described above, is associ- ated with tobacco product susceptibility and use among youth and young adults. P1 will analyze publicly available e-cigarette-related social media postings generated by participants in the TCORS’ Center-Wide cohort (recruited with support from the Population Core) and link the data to survey responses on tobacco product use. P1 tests the hypothesis that participants who engage with and disseminate youth-oriented tobacco messages about e- cigarettes will subsequently be more likely to report transitions to higher levels of tobacco product use. Integra- tion with “Intersections of Products with Populations” theme: P1 will study domains of product diversity studied in other USC-TCORS projects. P1 also is likely to identify novel domains of product diversity in Aim 1. P1 will address population diversity from a thematic perspective in social media messages by contrasting post- ings with themes meant to engage populations interested in switching to a lower risk product vs. vulnerable youth who are not using tobacco products. FDA Scientific domains addressed: Behavior and Marketing.

摘要：项目 1 (P1) 背景：社交媒体是接触新型电子烟产品的普遍渠道，尤其是对于 然而，几乎没有证据表明社交媒体和社交媒体上描述的电子烟产品的多样性。 社交媒体接触产品对烟草产品使用的影响 P1 旨在为 FDA 提供目标。 监管利用社交媒体作为平台来了解电子烟产品多样性并为监管提供信息 通过保护弱势的年轻非用户，同时考虑影响，使“整体人口”受益 针对已转用（或有兴趣转用）电子烟的成年吸烟者 方法：两种补充。 此项研究将解决两个目标： 1. 分析持续收集的电子烟社交媒体帖子。 和其他烟草产品相关的关键词，以确定表明产品趋势的发生模式 营销、有关电子烟产品及其多样化产品特征的对话。 1 将审查与针对非烟草使用者的面向青年的帖子同时出现的新关键词和主题， 针对当前吸烟者关于改用电子烟的健康帖子 P1 测试了这一假设。 将会有针对青少年主题的电子烟产品的帖子（即有关电子烟口味、 电子烟云、折扣和卡通）往往会同时出现，并且这些主题将是 不太可能与以健康为主题的电子烟产品的帖子同时出现（例如，声称减少 电子烟对自己和他人的危害，或关于戒烟 P1 也检验了消息的假设。 以年轻人为导向的主题将产生更多的用户参与（点赞）和传播（转发、分享） 目标 2. 确定是否参与（例如，发帖、点赞、分享）。 与香烟相关的社交媒体，尤其是上述包含青年主题的帖子，与 P1 将对青少年和年轻人的烟草产品易感性和使用情况进行分析。 TCORS 中心范围队列参与者（招募 在人口核心的支持下）并将数据与烟草产品使用的调查回复联系起来。 假设参与并传播面向青年的电子烟草信息的参与者 随后，卷烟将更有可能报告向更高水平的烟草产品使用转变。 以“产品与人口的交叉点”为主题：P1 将研究产品多样性领域 在其他 USC-TCORS 项目中进行的研究也可能会确定目标 1 中产品多样性的新领域。 P1 将从社交媒体信息的主题角度通过对比后社会来解决人口多样性问题。 其主题旨在吸引有兴趣转向低风险产品的人群，而不是弱势青少年 不使用烟草产品的人 FDA 涉及的科学领域：行为和营销。
