Purpose

The aim of this study is to examine US youths’ harm perceptions toward nondaily use of e-cigarettes, cigarettes, cigars, smokeless tobacco, and hookahs.

Methods

The nationally representative, cross-sectional National Youth Tobacco Survey annually assessed the following: “How much do you think people harm themselves when they [use tobacco products] some days but not every day?” Weighted estimates for 2020 were generated overall (grades 6–12) and by select demographics. Multivariable regression examined linear and quadratic changes during 2016–2020 (excluding cigars).

Results

In 2020, the prevalence of middle and high school students reporting “no” or “little” harm (vs. “some” or “a lot”) was 20.1% for e-cigarettes, 17.4% for hookahs, 14.6% for cigars, 13.5% for smokeless tobacco, and 11.0% for cigarettes. During 2016–2020, perceptions of “no” or “little” harm decreased for e-cigarettes, increased for cigarettes and smokeless tobacco, and exhibited nonlinear changes for hookahs.

Discussion

Most youth are aware of tobacco product harms, but opportunities exist to educate youth about the harms of nondaily tobacco product use.

2016-2020 年美国中学生对烟草制品危害的看法

目的

本研究的目的是调查美国青少年对非日常使用电子烟、香烟、雪茄、无烟烟草和水烟的危害认知。

方法

具有全国代表性、跨部门的全国青少年烟草调查每年都会评估以下内容：“您认为人们在某些天（但不是每天）[使用烟草制品] 时会伤害自己多少？” 2020 年的加权估计值是根据总体（6-12 年级）和选定的人口统计数据生成的。多变量回归检查了 2016-2020 年期间的线性和二次变化（不包括雪茄）。

结果

2020 年，报告“无”或“小”伤害（相对于“一些”或“很多”）的中学生的流行率为：电子烟为 20.1%，水烟为 17.4%，雪茄为 14.6%，无烟烟草为 13.5%，香烟为 11.0%。在 2016 年至 2020 年期间，对电子烟“无”或“小”危害的看法有所下降，而卷烟和无烟烟草则有所增加，而水烟则呈现出非线性变化。

讨论

大多数青年都知道烟草制品的危害，但有机会教育青年了解非日常使用烟草制品的危害。
