绝大多数美国年轻人每天使用Facebook和Instagram等社交媒体。研究表明，年轻人通常会在他们使用的社交媒体上接触到与电子烟相关的营销或用户生成的内容。然而，目前，关于社交媒体电子烟暴露如何与电子烟使用信念和行为相关的经验证据有限。特别是，存在有限的证据支持社交媒体电子烟暴露与电子烟使用唯一相关的主张，即使在调整年轻人亲自或“离线”社交网络中使用电子烟的影响之后。本研究旨在验证以下假设：1）社交媒体电子烟暴露与电子烟使用结果预期和当前电子烟使用相关; 2）社交媒体与电子烟使用之间的关联通过结果预期联系起来。我们收集了来自夏威夷的470名年轻成人大学生的横截面数据。通过将结构方程模型拟合到数据来检验假设。该模型考虑了人口统计学变量、吸烟史以及个人实际社交网络中电子烟的使用与预期和行为的关联。结果表明，社交媒体电子烟暴露与当前电子烟使用间接相关，通过检查的四个积极结果预期中的两个，即积极的“吸烟”体验和积极的感官体验。我们讨论了烟草控制工作的背景下的调查结果的影响。
A vast majority of U.S. young adults use social media such as Facebook and Instagram daily. Research suggests that young adults are commonly exposed to e-cigarette-related marketing or user-generated content on the social media they use. Currently, however, there is limited empirical evidence as to how social media e-cigarette exposure is associated with e-cigarette use beliefs and behavior. In particular, limited evidence exists to support the proposition that social media e-cigarette exposure is uniquely associated with e-cigarette use, even after adjusting for the effects of e-cigarette use in young adults' in-person or 'offline' social networks. This study was conducted to test the hypotheses that 1) social media e-cigarette exposure is associated with e-cigarette use outcome expectancies and current e-cigarette use; and 2) the association between social media and e-cigarette use is linked via outcome expectancies. We collected cross-sectional data from a sample of 470 young adult college students in Hawaii. Hypotheses were tested by fitting a structural equation model to the data. The model accounted for the associations of demographic variables, cigarette smoking history, as well as e-cigarette use in individuals' actual social networks with expectancies and behavior. Results indicated that social media e-cigarette exposure was associated with current e-cigarette use indirectly through two of the four positive outcome expectancies examined, namely, positive "smoking" experience and positive sensory experience. We discuss the implications of the findings in the context of tobacco control efforts.
