@Article{info:doi/10.2196/12676，作者=“Chu, Kar-Hai和Majmundar, Anuja和Allem, Jon-Patrick和Soto, Daniel W和Cruz, Tess Boley和Unger, Jennifer B”，标题=“烟草意见领袖及其追随者的烟草使用行为、态度和人口特征:Twitter分析”，期刊=“J Med Internet Res”，年=“2019”，月=“6”，日=“04”，卷=“21”，号=“6”，页=“e12676”，关键词=“烟草;社交媒体;在线社交网络;同伴的影响;背景:社交媒体上与烟草相关的内容是由网络上的意见领袖产生和传播的，他们将信息传播给其网络中的其他人，包括追随者，然后这些人继续传播这些信息。意见领袖可以对其追随者的知识、态度和行为产生强大的影响;然而，与普通Twitter用户相比，人们对网络上的烟草意见领袖及其追随者的人口统计学特征和烟草使用行为知之甚少。目的:在本研究中，我们假设意见领袖比其他两组(如追随者和普通Twitter用户)使用更多的烟草产品，对尼古丁的依赖程度更高，而追随者——那些传播意见领袖信息的人——更有可能属于易受烟草营销影响的人口群体(如年轻人和受教育程度较低的人)。方法:我们构建了推特上关于烟草的人的社交网络，并使用社交网络和推特指标的组合对他们进行分类。为了了解烟草意见领袖及其追随者的特征，我们对烟草意见领袖、他们的追随者和一般Twitter用户进行了调查。 The sample included 347 opinion leaders, 567 followers, and 519 general users. The opinion leaders had a median of 1000 followers, whereas followers and general users had fewer than 600 followers. Results: Opinion leaders were more likely than their followers to report past month use of tobacco products; followers, in turn, were more likely to report past month use of these products than general Twitter users. The followers appeared to be an especially vulnerable group; they tended to be younger (mean age 22.4 years) and have lower education compared with the opinion leaders and general users. Conclusions: Followers of Twitter tobacco opinion leaders are a vulnerable group that might benefit from antitobacco education to counter the protobacco communications they see on social media.
