This study proposes the following research questions: (1) Does e-cigarette use status influence intentions to engage with anti-vaping Instagram posts?, and (2) How are e-cigarette use and social media use associated? We recruited a convenience sample of young adults (N = 459; aged 18\u201330 years) in July of 2022 into an online experimental study from Prolific. Participants saw five image-based Instagram posts about the health harms of using e-cigarettes. Participants were then asked about their intentions to engage (\u201cComment on\u201d, \u201cReshare\u201d, \u201cDM\/Send this to a friend\u201d, \u201cLike\u201d, and\/or \u201cTake a screenshot of\u201d) with the posts. We used logistic regression to run adjusted models for each engagement outcome, which included fixed effects for sociodemographics, tobacco use, and social media\/internet use. For the sum of the engagement outcome, we used Poisson regression. Total number of social media sites used was associated with intentions to \u201cLike\u201d the posts (p = 0.025) and the overall engagement score (p = 0.019), respectively. Daily internet use was associated with intentions to \u201cComment on\u201d (p = 0.016) and \u201cLike\u201d (p = 0.019) the posts. Young adults who reported past 30-day e-cigarette use had higher odds of using Twitter (p = 0.013) and TikTok (p &lt; 0.001), and a higher total number of social media sites used (p = 0.046), compared to young adults who reported never use e-cigarettes. The initial evidence from our exploratory research using a convenience sample suggests that social media campaigns about the harms of e-cigarette use may be an effective way to engage younger audiences, a generation that frequents social media. Efforts to disseminate social media campaigns should consider launching on multiple platforms, such as Twitter and TikTok, and consider e-cigarette use status when posting.<\/jats:p>","DOI":"10.3390\/ijerph20116054","type":"journal-article","created":{"date-parts":[[2023,6,6]],"date-time":"2023-06-06T02:08:15Z","timestamp":1686017295000},"page":"6054","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Characteristics Associated with Young Adults\u2019 Intentions to Engage with Anti-Vaping Instagram Posts"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8455-0127","authenticated-orcid":false,"given":"Jessica","family":"Liu","sequence":"first","affiliation":[{"name":"Department of Social and Behavioral Sciences, Harvard T.H.
