Alternative tobacco use among adolescents who smoke cigarettes is a growing public health concern, and evidence suggests that patterns of alternative tobacco use varies with respect to cigarette consumption and frequency of cigarette use. This study aimed to examine (a) whether variations in adolescent cigarette smoking and alternative tobacco use can be explained by underlying subtypes and (b) if these subtypes differ in their demographic and psychosocial characteristics.
Using data from the 2009 National Youth Tobacco Survey, latent class analysis (LCA) was used to identify patterns of cigarette smoking and alternative tobacco use among 2746 current (past 30-day) smokers. After identification, classes were analyzed using multinomial logistic regression to examine differences based on demographics and smoking-related characteristics.
Four of the six latent classes identified (non-daily light smokers, chippers, chippers-Indulgent, intermittent smokers) reflected consumption, frequency, and history of cigarette use characteristics commonly attributed to light and intermittent smokers, and the remaining two classes (daily smokers, daily smokers-Indulgent) presented cigarette use behaviors commonly attributed to daily smokers. There were clear class differences in levels of alternative tobacco product use, demographics, and psychosocial characteristics.
Study findings are consistent with previous work demonstrating demographic and psychosocial differences between cigarette smokers based on their alternative tobacco use. The six latent classes identified highlight the importance of including measures of alternative tobacco use when characterizing adolescent cigarette smokers as well as recognizing and tailoring interventions toward these different groups of tobacco users.
青少年在吸烟的同时使用其他烟草制品是一个日益严重的公共卫生问题,有证据表明,替代烟草制品的使用模式因吸烟量和吸烟频率的不同而有所不同。本研究旨在检验:(a)青少年吸烟和使用替代烟草制品的差异是否可以用潜在的亚类来解释;(b)这些亚类在人口统计学和心理社会特征上是否存在差异。
本研究使用了 2009 年全国青少年烟草调查的数据,采用潜在类别分析(LCA)来识别 2746 名当前(过去 30 天)吸烟者中吸烟和使用替代烟草制品的模式。在确定了这些模式之后,采用多项逻辑回归分析来检查基于人口统计学和吸烟相关特征的差异。
识别出的六个潜在类别中的四个(非每日轻度吸烟者、浅尝者、浅尝者-放纵者、间歇性吸烟者)反映了吸烟量、频率和吸烟史的特征,这些特征通常与轻度和间歇性吸烟者有关,其余两个类别(每日吸烟者、每日吸烟者-放纵者)则呈现出通常与每日吸烟者有关的吸烟行为。在替代烟草制品的使用水平、人口统计学和心理社会特征方面存在明显的类别差异。
研究结果与先前的工作一致,即根据替代烟草制品的使用情况,吸烟青少年在人口统计学和心理社会特征上存在差异。识别出的六个潜在类别强调了在描述青少年吸烟者时纳入替代烟草制品使用情况的重要性,以及认识和针对这些不同群体的烟草使用者进行干预的重要性。
