Changes to the U.S. smokeless tobacco landscape in recent years include a change to health warnings on packages, the implementation of bans in some stadiums, and the launch of a federal youth prevention campaign. It is unclear whether such changes have impacted consumer beliefs about smokeless tobacco. This study examines relative harm perceptions of smokeless tobacco compared to cigarettes among adults and assesses changes in smokeless tobacco harm perceptions over time.
We analyzed data from three cycles (2012, 2014, 2015) of the Health Information National Trends Survey (HINTS). Using 2015 data, we assessed bivariate associations between smokeless tobacco harm perceptions and tobacco use, beliefs, information seeking, and demographics. Using 2012, 2014, and 2015 data, we assessed whether smokeless tobacco harm perceptions changed over time within demographic groups using chi-square tests. We then used a weighted multinomial logistic regression to assess the association between smokeless tobacco perceptions and survey year, adjusting for covariates.
When asked whether smokeless tobacco products are less harmful than cigarettes, the majority of respondents across cycles said "no." The percent of respondents who selected this response option decreased over time. Findings showed significant differences in relative harm perceptions of smokeless tobacco versus cigarettes for specific demographic subgroups. Among subgroups, these shifts did not occur with a discernible pattern.
Understanding factors associated with perceptions of smokeless tobacco can inform tobacco control efforts. Additional monitoring of these trends may provide researchers with a deeper understanding of how and why smokeless tobacco harm perceptions change.
近年来,美国无烟气烟草领域发生了变化,包括包装上健康警告的改变、一些体育场的禁烟令的实施,以及联邦青年预防运动的开展。目前尚不清楚这些变化是否影响了消费者对无烟气烟草的看法。本研究考察了成年人对无烟气烟草相对危害的认知与对香烟的危害认知相比的情况,并评估了随着时间的推移,对无烟气烟草危害认知的变化。
我们分析了三个周期(2012 年、2014 年和 2015 年)的健康信息国家趋势调查(HINTS)的数据。使用 2015 年的数据,我们评估了对无烟气烟草危害认知与烟草使用、信念、信息寻求和人口统计学之间的双变量关联。使用 2012 年、2014 年和 2015 年的数据,我们使用卡方检验评估了在人口统计学群体中,无烟气烟草危害认知是否随时间变化。然后,我们使用加权多项逻辑回归来评估无烟气烟草感知与调查年份之间的关联,同时调整了协变量。
当被问及无烟气烟草制品是否比香烟危害小,大部分受访者在各周期都回答“否”。选择此回答选项的比例随着时间的推移而下降。研究结果显示,在特定的人口统计学亚组中,无烟气烟草与香烟的相对危害认知存在显著差异。在这些亚组中,这些变化没有呈现出明显的模式。
了解与无烟气烟草认知相关的因素可以为烟草控制工作提供信息。对这些趋势的进一步监测可以为研究人员提供更深入的理解,了解无烟气烟草危害认知是如何以及为何发生变化的。
