Studies have identified a proliferation of e-cigarette advertisements on Twitter. We investigate whether the prevalence of e-cigarette related advertising is associated with state tobacco regulations after taking socio-economic characteristics into account.
We collected e-cigarette related tweets from July 23 to October 14, 2015 (n = 757,167) on Twitter. State regulations and smoking prevalence were provided by the Campaign for Tobacco-Free Kids program. The socio-economic data were provided by the American Community Survey.
The number of commercial tweets was 319,041/day with a high potential reach (830,495,700/day). The prevalence of commercial tweets varied significantly by US state. The higher prevalence of e-cigarette advertising was associated with states with better tobacco control impact (r = 0.54, p < 0.0001) and lower youth smoking prevalence (r = -0.39, p = 0.005). In the multivariate analysis, state tobacco control impact is significantly associated with the prevalence of commercial tweets (β = 0.03 ± 0.01, p = 0.02).
Policies at both the federal and state levels are needed to regulate the content of commercial tweets and mitigate the negative effect of social media advertisements.
研究发现推特上电子烟广告大量涌现。我们在考虑社会经济特征后，调查电子烟相关广告的流行程度是否与州烟草法规相关。
我们于2015年7月23日至10月14日在推特上收集了与电子烟相关的推文（n = 757,167）。无烟儿童运动项目提供了州法规和吸烟率数据。社会经济数据由美国社区调查提供。
商业推文数量为每天319,041条，潜在覆盖面广（每天830,495,700人次）。商业推文的流行程度在美国各州差异显著。电子烟广告流行程度较高与烟草控制效果较好的州相关（r = 0.54，p < 0.0001），与青少年吸烟率较低相关（r = -0.39，p = 0.005）。在多变量分析中，州烟草控制效果与商业推文的流行程度显著相关（β = 0.03 ± 0.01，p = 0.02）。
需要联邦和州层面的政策来规范商业推文内容，减轻社交媒体广告的负面影响。
