Limited information exists on multiple tobacco product use, particularly among youth. This study assessed the prevalence of current youth use of e-cigarettes with other tobacco products and their associated characteristics using 2020 National Youth Tobacco Survey data.
Prevalence estimates were calculated for current e-cigarette users, by multiple tobacco product use status and product combination. Demographic characteristics, e-cigarette use behaviors, age at first combustible tobacco use, and tobacco dependence symptoms were compared between current users of both e-cigarettes and combustible tobacco (dual users) and current exclusive e-cigarette users.
In 2020, 61.1% of all current e-cigarette users reported exclusive e-cigarette use, and 38.9% used e-cigarettes with other tobacco products. Among those who used e-cigarettes with other tobacco products, 85.0% used combustible tobacco, with cigarettes being the most commonly used other tobacco product. Compared with current exclusive e-cigarette users, higher proportions of dual users reported the following: frequent e-cigarette use; obtaining e-cigarettes from gas stations, persons other than a family member/friend, vape shops, or the internet; and having any tobacco dependence symptoms. Among dual users, 31.2% reported first combustible product use after e-cigarette initiation, and 34.3% reported first combustible product use prior to e-cigarette initiation.
Approximately four in 10 youth current e-cigarette users reported using multiple tobacco products, with a majority using combustible tobacco. Frequent e-cigarette use and tobacco dependence symptoms were more prevalent among dual users of e-cigarettes and combustible tobacco.
关于多种烟草制品的使用，尤其是在青少年中的使用情况，相关信息有限。本研究利用 2020 年全国青少年烟草调查数据，评估了当前青少年使用电子烟与其他烟草制品的情况及其相关特征。
根据是否同时使用多种烟草制品及其组合，计算当前电子烟使用者的流行率。比较同时使用电子烟和可燃烟草（双重使用者）以及仅使用电子烟的当前使用者在人口统计学特征、电子烟使用行为、首次使用可燃烟草的年龄以及烟草依赖症状等方面的差异。
2020 年，所有当前电子烟使用者中，有 61.1%报告仅使用电子烟，38.9%同时使用电子烟和其他烟草制品。在同时使用电子烟和其他烟草制品的人群中，85.0%使用可燃烟草，其中香烟是最常使用的其他烟草制品。与仅使用电子烟的当前使用者相比，双重使用者报告以下情况的比例更高：频繁使用电子烟；从加油站、非家庭成员/朋友、电子烟商店或互联网获得电子烟；存在任何烟草依赖症状。在双重使用者中，31.2%报告在开始使用可燃烟草产品后开始使用电子烟，34.3%报告在开始使用电子烟之前就开始使用可燃烟草产品。
大约十分之四的当前电子烟使用者报告同时使用多种烟草制品，其中大多数人使用可燃烟草。同时使用电子烟和可燃烟草的双重使用者中，频繁使用电子烟和存在烟草依赖症状的情况更为普遍。
