Vaping-related news events and their relationship with sentiment in the online vaping environment: A computational interrupted time series analysis with large-scale public data
Abstract Background: Vaping-related news coverage may have furthered misconceptions around the relative harms of vapes. Also, some positive opinions around vaping may be derived from misinformation, perhaps creating inimical health outcomes. Thus, we need to study how vaping-related news events (e.g. 2019 vaping illness epidemic, COVID-19) are associated with sentiment in the online vaping environment, to better understand how to promote vaping as a potential harm reduction technique for those who smoke and are unable to quit, and to minimize vape-centric misinformation that could lead to reduced health outcomes. Methods: We obtained vaping-related online data through web-scraping several online environments from August 1 2019 - April 21 2020. Sentiment analysis was performed to understand changes in sentiment in the online vaping environment in relation to vaping-related events, such as the Trump administration's planned ban on flavored vaping products, and when COVID-19 was first reported to the WHO. Results: For all online environments, we observed a statistically significant negative association of 15% (Estimate: -0.16; 95% CI: -0.29, -0.03; P: 0.01) between sentiment score and the Trump administration's move towards a ban on flavored vaping products, and a statistically significant positive association of 7% between sentiment score (Estimate: 0.07; 95% CI: 0.01, 0.14; P: 0.02) and when COVID-19 was first reported to the WHO (December 31 2019). Conclusions: News events may be related to sentiment in the online vaping environment, depending on the event. Depending on the nature of the event, we suggest that public health messaging may improve health outcomes.
