Beliefs that flavored smokeless tobacco (ST) is more pleasant, less potent, or otherwise easier to use could contribute to youth initiation. We evaluated associations between perceived ease-of-use of flavored ST (moist snuff and chewing tobacco) and ST initiation susceptibility in a representative sample of US youth.
Among 7,718 tobacco never-users in the Population Assessment of Tobacco and Health study (age: 12-17; collected: 2013-2014), we compared 4 ST susceptibility items (curiosity, expectation, willingness to try, and a composite) according to whether participants reported flavored ST to be "easier to use" than unflavored ST. We calculated marginal prevalences of ST susceptibility and odds ratios adjusted for socio-demographic characteristics, tobacco advertisement receptivity, warning label exposure, and sensation seeking.
ST susceptibility was greatest among tobacco never-users who perceived flavored ST as easier to use. Adjusted odds of potential ST susceptibility (≥1 item) were 1.5-fold higher (95% confidence interval: 1.2, 1.8) among adolescents who perceived flavored ST as easier to use than unflavored ST.
ST flavors could contribute to perceptions that facilitate youth initiation. Alternatively, youth susceptible to ST use may perceive flavored varieties differently. Prospective studies are warranted to strengthen causal evidence and measure ST initiation according to perceived ease-of-use.
认为调味无烟烟草(ST)更宜人、效力更低或使用起来更方便的观念可能会促使青少年开始使用。我们在美国青少年的代表性样本中评估了调味ST(湿鼻烟和嚼烟)的易用性感知与开始使用ST的易感性之间的关联。
在烟草与健康人口评估研究中的7718名从不使用烟草者中(年龄:12 - 17岁;收集时间:2013 - 2014年),我们根据参与者是否报告调味ST比未调味ST“更容易使用”,比较了4个ST易感性项目(好奇心、期望、尝试意愿和一个综合项目)。我们计算了ST易感性的边际患病率以及针对社会人口特征、烟草广告接受度、警示标签暴露和寻求刺激进行调整后的比值比。
在认为调味ST更容易使用的从不使用烟草者中,ST易感性最高。在认为调味ST比未调味ST更容易使用的青少年中,潜在ST易感性(≥1个项目)的调整后比值比高1.5倍(95%置信区间:1.2,1.8)。
ST的口味可能会导致一些认知,从而促进青少年开始使用。或者,易使用ST的青少年可能对调味品种有不同的认知。有必要进行前瞻性研究以加强因果证据,并根据感知的易用性来衡量ST的开始使用情况。
