Abstract：
OBJECTIVE: Disposable electronic cigarette (e-cigarette) use is becoming more popular among US youth, given the shifting landscape in product marketing, availability and regulation. This study aimed to estimate the prevalence of and test factors associated with the most used e-cigarette product (disposable versus other) among US youth aged 9-18 years who currently use e-cigarettes.
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.

摘要：
目标：一次性电子烟（电子烟）的使用在美国年轻人中越来越受欢迎，考虑到产品营销的变化，可用性和监管。这项研究旨在评估目前使用电子烟的9-18岁美国年轻人中最常用的电子烟产品（一次性与其他）的患病率和测试因素。
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。
