There is an increased need to understand how e-cigarette flavors may contribute to e-cigarette uptake and use among youth. We examined the relationship between perceived ease of flavored e-cigarette use and e-cigarette use susceptibility and progression among a nationally representative sample of U.S. youth never tobacco users.
The wave 1 (2013-2014) and wave 2 (2014-2015) surveys of PATH Study were used. Youth never tobacco users (ages 12-17) who reported whether flavored e-cigarettes were easier to use than unflavored e-cigarettes at wave 1 (n = 6,983) were included in the study. Multivariable logistic regressions were used to examine the associations between perceived ease of using flavored e-cigarettes (wave 1) and e-cigarette use outcomes including e-cigarette use susceptibility (wave 1) and e-cigarette initiation and past-30-day use (wave 2).
Overall, 21.2% of the sample perceived flavored e-cigarettes easier to use than unflavored e-cigarettes; and 28.9% of the sample were susceptible to using e-cigarettes at wave 1, and 7.5% and 2.0% initiated e-cigarettes and used e-cigarettes in the past 30 days at wave 2, respectively. Among those who perceived flavored e-cigarettes easier to use, 41.0% were susceptible to using e-cigarettes at wave 1, and 10.6% and 3.4% initiated and used e-cigarettes in the past 30 days at wave 2, respectively. Perceiving flavored e-cigarettes as easier to use than unflavored e-cigarettes at wave 1 was positively associated with e-cigarette use susceptibility at wave 1 (AOR = 1.43, CI = 1.21, 1.69), and e-cigarette initiation (AOR = 1.32, CI = 1.12, 1.67) and past-30-day use (AOR = 1.25, CI = 1.10, 2.47) at wave 2.
Perceiving flavored e-cigarettes as easier to use than unflavored e-cigarettes may lead to e-cigarette use progression among youth never tobacco users. Determining the factors (including e-cigarette marketing and specific e-cigarette flavors) that lead to perceived ease of using flavored e-cigarettes would inform efforts to prevent and curb youth e-cigarette use.
人们越来越需要了解电子烟口味如何促使年轻人吸食和使用电子烟。我们研究了感知电子烟使用的便利性与美国青少年从未使用过烟草的人群中电子烟使用易感性和进展之间的关系。
我们使用了 PATH 研究的第 1 波（2013-2014 年）和第 2 波（2014-2015 年）调查。在第 1 波调查中报告电子烟口味电子烟比无味电子烟更容易使用的从未使用过烟草的青少年（年龄 12-17 岁）（n = 6983）被纳入研究。多变量逻辑回归用于检验感知使用电子烟口味电子烟更容易使用（第 1 波）与电子烟使用结果之间的关联，包括电子烟使用易感性（第 1 波）和电子烟使用起始和过去 30 天使用（第 2 波）。
总体而言，21.2%的样本认为电子烟口味电子烟比无味电子烟更容易使用；28.9%的样本在第 1 波对电子烟使用易感，分别有 7.5%和 2.0%在第 2 波起始和过去 30 天内使用电子烟。在那些认为电子烟口味电子烟更容易使用的人群中，41.0%的人在第 1 波对电子烟使用易感，分别有 10.6%和 3.4%在第 2 波起始和过去 30 天内使用电子烟。在第 1 波中感知电子烟口味电子烟比无味电子烟更容易使用，与第 1 波电子烟使用易感性（优势比 [AOR] = 1.43，95%置信区间 [CI] = 1.21，1.69），以及电子烟使用起始（AOR = 1.32，CI = 1.12，1.67）和过去 30 天内使用（AOR = 1.25，CI = 1.10，2.47）呈正相关。
感知电子烟口味电子烟比无味电子烟更容易使用可能导致青少年从未使用过烟草的人群中电子烟使用进展。确定导致感知电子烟口味电子烟使用便利性的因素（包括电子烟营销和特定电子烟口味）将有助于预防和遏制青少年电子烟使用。
