RESUMEN
INTRODUCTION: 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. METHODS: 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). RESULTS: 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. CONCLUSION: 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.
RESUMEN
Introduction: Use of telehealth increased during the COVID-19 pandemic and continues to be a popular health resource. This study analyzed the frequency and sentiment of telehealth discussions on Reddit. Methods: The data set included 13,071 publicly available Reddit submissions containing keywords related to telehealth over a 3-year period. We identified 173 unique subreddit communities, which were coded into mutually exclusive categories: (1) general telehealth, (2) individual care, (3) professional, (4) news, and (5) COVID-19. The Vader lexicon-based machine was used to assign sentiment scores. Results: Most subreddits were coded as individual care (n = 112), professional (n = 26), and news (n = 22). The frequency of submissions increased during the first 2 months of the pandemic and dropped in June 2020, but remained consistent through October 2022. Most Reddit submissions were positive in sentiment (56%). Conclusion: Findings show a mostly positive view of telehealth among Reddit users and an increase in telehealth-related discussions since the COVID-19 pandemic.
