METHODS: This was an observational study using cross-sectional data from the US-based 2021 and 2022 National Youth Tobacco Surveys (n = 48 704). We restricted our analytical sample to youth who currently use e-cigarettes (n = 4137). The sample ranged from 9 to 18 years old and was 53.0% female.
METHODS: We dichotomized e-cigarette device type to disposable versus all other types (e.g. refillable pods/cartridges). We conducted logistic regression to estimate whether age, sex, race/ethnicity, sexual orientation, frequency of e-cigarette use, nicotine vaping, flavored e-cigarette use and current combustible/non-combustible tobacco use were associated with disposable e-cigarette use, compared with other e-cigarette use.
RESULTS: Among youth who currently use e-cigarettes, 54.5% used disposable e-cigarettes. Older age (17-18 years), relative to younger age (9-14 years) [odds ratio (OR) = 1.43, 95% confidence interval (CI) = 1.07-1.91], non-Hispanic Black (versus non-Hispanic White) race/ethnicity (OR = 1.47, 95% CI = 1.01-2.15), any nicotine (versus non-nicotine) vaping (OR = 2.51, 95% CI = 1.96-3.23) and flavored (versus non-flavored) e-cigarette use (OR = 1.93, 95% CI = 1.46-2.56) were associated with increased odds of mainly using disposable e-cigarettes, compared with using other e-cigarette products, whereas current combustible tobacco use (versus non-current) (OR = 0.65, 95% CI = 0.53-0.80) and current non-combustible tobacco use (versus non-current) (OR = 0.58, 95% CI = 0.43-0.78) were associated with lower odds.
CONCLUSIONS: Disposable e-cigarettes appear to be the most used type of e-cigarette product among US youth. Older age, non-Hispanic Black race/ethnicity, nicotine vaping and flavored e-cigarette use are associated with mainly using disposable e-cigarettes, relative to other e-cigarette products.
方法:这是一项观察性研究,使用来自美国2021年和2022年全国青年烟草调查的横截面数据(n=48704)。我们将我们的分析样本限制在目前使用电子烟的年轻人(n=4137)。样本范围为9至18岁,女性占53.0%。
方法:我们将电子烟设备类型分为一次性和所有其他类型(例如可再填充的豆荚/烟弹)。我们进行了逻辑回归来估计年龄,性别,种族/民族,性取向,电子烟的使用频率,尼古丁汽化,调味电子烟的使用和当前可燃/不可燃烟草的使用与一次性电子烟的使用有关,与其他电子烟相比。
结果:在目前使用电子烟的年轻人中,54.5%使用一次性电子烟。年龄较大(17-18岁),相对于较年轻的年龄(9-14岁)[优势比(OR)=1.43,95%置信区间(CI)=1.07-1.91],非西班牙裔黑人(与非西班牙裔白人)种族/种族(OR=1.47,95%CI=1.01-2.15),任何尼古丁(与非尼古丁)蒸发(OR=2.51,95%CI=1.96-3.23)和调味(与非调味)电子烟使用(OR=1.93,95%CI=1.46-2.56)与主要使用一次性电子烟的几率增加有关,与使用其他电子烟产品相比,而当前的可燃烟草使用(相对于非当前)(OR=0.65,95%CI=0.53-0.80)和当前的不可燃烟草使用(相对于非当前)(OR=0.58,95%CI=0.43-0.78)与较低的几率相关.
结论:一次性电子烟似乎是美国年轻人中使用最多的电子烟产品。年纪大了,非西班牙裔黑人种族/种族,尼古丁电子烟和调味电子烟的使用与主要使用一次性电子烟有关,相对于其他电子烟产品。
