项目摘要

PROJECT SUMMARY I was awarded my first R01 (parent grant) on June 1, 2020. However, the university-wide hiring freeze due to the COVID-19 pandemic and the birth of my child and maternity leave set back the project progress. Thus, this Administrative Supplement, which is focused on supporting first-time grantees who experienced critical life events, will be used to catch up on the delayed progress from Year 1 of the parent grant. Please note that the Specific Aims of this Supplement remain the same as those of the parent grant. The overall goal of the parent grant is to understand ways in which youth modify e-cigarettes, their motivations for doing so, and marketing sources, using YouTube analysis, survey methodology, and expert evaluation. We will identify modified uses of e-cigarettes and marketing using fictitious youth YouTube viewer profiles to search for e-cigarettes using a browser plug-in and custom scripted web-crawling and then machine learning to automatically code the videos to identify e-cigarette modifications and marketing source. Our Advisory Committee (AC) of subject matter experts in tobacco regulatory science, social media, youth tobacco use, toxicology, communications, and tobacco marketing will apply their knowledge to assess the potential impact of these identified modified uses on appeal, addiction, and health effects of e-cigarettes to identify those which are amenable to FDA regulations and communications. We will then conduct an in-depth analysis of these selected behaviors using a combination of machine learning and detailed human coding on youth-accessible YouTube videos to understand: 1) components that are modified (e.g., batteries, cartridges/pods, e-liquids), 2) motivations for modification (e.g., enhance user experience, reduce perceived harm), 3) marketing sources (e.g., online shops, pro-e-cigarette organizations), and 4) appeal (number of likes, views). We will also use an online survey with adolescent and young adult e-cigarette users (N=1000) to examine the prevalence, appeal, motivations, risk perceptions, and marketing exposure related to these modified uses and their predictors (i.e., demographic variables, past-month e-cigarette use frequency, e-cigarette dependence, other tobacco/substance use, interpersonal and intrapersonal risk factors). The results of this study will provide the FDA with novel evidence to 1) develop regulations to prohibit the manufacturing and marketing of e-cigarette components that can be modified by youth, 2) restrict youth-accessible marketing of e-cigarettes on social media such as YouTube, and 3) develop prevention campaigns to educate youth about the harms of modifying e-cigarettes.

项目概要我于 2020 年 6 月 1 日获得了我的第一个 R01（家长补助金）。然而，由于 COVID-19 大流行以及我孩子的出生和产假阻碍了项目的进展。因此，这个行政补助，重点支持经历过危急生活的首次受助者事件，将用于赶上第一年家长补助金的延迟进度。请注意，本补充协议的具体目标与母基金的具体目标相同。该项目的总体目标是家长补助金是为了了解青少年修改电子烟的方式，他们这样做的动机，和营销来源，使用 YouTube 分析、调查方法和专家评估。我们将使用虚构的青年 YouTube 观看者个人资料来识别电子烟的修改用途和营销使用浏览器插件和自定义脚本网络爬行的电子烟，然后机器学习自动对视频进行编码以识别电子烟修改和营销来源。我们的咨询烟草监管科学、社交媒体、青少年烟草使用等主题专家委员会 (AC) 毒理学、传播学和烟草营销人员将运用他们的知识来评估潜在影响这些确定了电子烟对吸引力、成瘾性和健康影响的修改用途，以确定那些遵守 FDA 法规和沟通。接下来我们将对这些进行深入分析结合机器学习和详细的人类编码来选择青少年可访问的行为 YouTube 视频可帮助您了解：1) 改装的组件（例如电池、烟弹/烟弹、电子烟油），2) 修改的动机（例如，增强用户体验、减少感知伤害），3）营销来源（例如，网上商店、支持电子烟的组织），以及 4) 吸引力（点赞数、浏览量）。我们还将使用一个对青少年和年轻成人电子烟使用者（N = 1000）进行在线调查，以检查流行率、吸引力、与这些修改用途及其预测因素相关的动机、风险认知和营销曝光（即，人口统计变量、过去一个月的电子烟使用频率、电子烟依赖性、其他烟草/药物使用、人际和个人内部风险因素）。这项研究的结果将提供 FDA 拥有新证据 1）制定法规禁止电子烟的制造和营销青少年可以修改的组件，2) 限制青少年在社交媒体上进行电子烟营销 YouTube 等媒体，以及 3) 开展预防活动，教育青少年了解修改的危害电子烟。
