Introduction

Multiple tobacco product (MTP) use is a growing public health concern, particularly among adolescents and young adults. This study identifies subgroups of MTP use among cigarillo users and examines associations with nicotine dependence (ND).

Methods

1,089 youth (ages 14-28) who currently smoke cigarillos completed a web-based survey regarding their current use of cigarillos, little cigars, traditional cigars, cigarettes, e-cigarettes, and waterpipe/hookah. Latent class analysis (LCA) was used to identify patterns of product use by type and amount. The LCA also assessed the relationship between the latent classes and a 38-item measure of ND, controlling for relevant demographics.

Results

Most participants (88.2%) reported using two or more tobacco products in the past 30 days. The best-fitting LCA solution revealed 7 classes: (1) Mixed-Light tipped cigarillo and light cigarette users, 28.9%; (2) Light tipped cigarillo users, 15.8%; (3) Light untipped cigarillo users, 14.3%; (4) Heavy tipped cigarillo users, 13.4%; (5) E-cigarette and waterpipe users, 11.9%; (6) Heavy users of tipped and untipped cigarillos and light users of cigarettes, 9.8%; and (7) Dabblers who primarily used traditional cigars, but were also likely to use a variety of other products, 6.1%. Classes comprised of those using multiple products—particularly those that included cigarettes—had significantly higher levels of ND than other classes (Tukey’s HSD P < .05).

Conclusions

Distinct patterns of MTP use are evident among young cigarillo smokers. Smoking multiple products, particularly smoking cigarillos in combination with cigarettes, is associated with higher ND compared to other product use patterns.

青少年和年轻人的小雪茄和多种烟草制品的使用和尼古丁依赖。

介绍

多种烟草制品 (MTP) 的使用是一个日益严重的公共卫生问题，尤其是在青少年和年轻人中。这项研究确定了小雪茄使用者使用 MTP 的亚组，并检查了与尼古丁依赖 (ND) 的关联。

方法

1,089 名目前吸食小雪茄的青年（14-28 岁）完成了一项关于他们目前使用小雪茄、小雪茄、传统雪茄、香烟、电子烟和水烟/水烟的网络调查。潜在类别分析 (LCA) 用于按类型和数量确定产品使用模式。LCA 还评估了潜在类别与 38 项 ND 测量之间的关系，控制了相关人口统计数据。

结果

大多数参与者 (88.2%) 报告在过去 30 天内使用两种或两种以上烟草制品。最合适的 LCA 解决方案显示了 7 个类别：(1) 混合轻型雪茄和轻型卷烟用户，28.9%；(2) 小雪茄使用者，15.8%；(3) 轻型无头小雪茄使用者，14.3%；(4) 雪茄重度使用者，13.4%；（5）电子烟和水烟用户，11.9%；(6) 吸头和不吸头小雪茄的重度使用者和卷烟的轻度使用者，9.8%；(7) 主要使用传统雪茄，但也可能使用各种其他产品的涉猎者，6.1%。由使用多种产品的人组成的类别（尤其是那些包括香烟的类别）的 ND 水平明显高于其他类别（Tukey 的 HSD P < .05）。

结论

MTP 使用的不同模式在年轻的小雪茄吸烟者中很明显。与其他产品使用模式相比，同时吸食多种产品，尤其是同时吸食小雪茄和卷烟，与更高的 ND 相关。
