The use of flavored electronic cigarettes (e-cigarettes) is common among e-cigarette users, but little is known about the potential harms of flavorings, the extent to which the concurrent use of multiple flavor types occurs, and the correlates of flavor type use. The objective of this study was to assess the types of e-cigarette flavors used by adolescent (aged 12-17), young adult (aged 18-24), and older adult (aged ≥25) e-cigarette users.
We assessed the prevalence of flavored e-cigarette use within the past month by flavor types and concurrent use of multiple flavor types among past-month e-cigarette users sampled during Wave 2 (2014-2015) of the Population Assessment for Tobacco and Health Study among 414 adolescents, 961 young adults, and 1711 older adults. We used weighted logistic regression models for the use of fruit-, candy-, mint/menthol-, tobacco-, or other-flavored e-cigarettes and concurrent use of multiple flavor types. Covariates included demographic characteristics, e-cigarette use frequency, cigarette smoking status, current use of other tobacco products, and reasons for e-cigarette use.
The leading e-cigarette flavor types among adolescents were fruit, candy, and other flavors; among young adults were fruit, candy, and mint/menthol; and among older adults were tobacco or other flavors, fruit, and mint/menthol. Compared with older adults, adolescents and young adults were more likely to use fruit-flavored e-cigarettes (adjusted odds ratio [aOR] = 3.35; 95% confidence interval [CI], 2.56-4.38; and aOR = 2.31; 95% CI, 1.77-3.01, respectively) and candy-flavored e-cigarettes (aOR = 3.81; 95% CI, 2.74-5.28; and aOR = 2.95; 95% CI, 2.29-3.80, respectively) and concurrently use multiple flavor types (aOR = 4.58; 95% CI, 3.39-6.17; and aOR = 2.28; 95% CI, 1.78-2.91, respectively).
Regulation of sweet e-cigarette flavors (eg, fruit and candy) may help reduce the use of e-cigarettes among young persons without substantially burdening adult e-cigarette users.
调味电子烟（e-cigarette）在电子烟使用者中很常见，但人们对调味剂的潜在危害、同时使用多种口味的程度以及口味使用的相关因素知之甚少。本研究的目的是评估青少年（12-17 岁）、年轻成年人（18-24 岁）和老年成年人（≥25 岁）电子烟使用者使用的电子烟口味类型。
我们评估了在 2014-2015 年期间进行的人口评估烟草和健康研究第二波（Wave 2）中，过去一个月内使用过电子烟的青少年（414 人）、年轻成年人（961 人）和老年成年人（1711 人）中，按口味类型评估过去一个月内使用调味电子烟的流行程度，以及同时使用多种口味类型的情况。我们使用加权逻辑回归模型评估水果味、糖果味、薄荷/薄荷醇味、烟草味或其他口味的电子烟以及同时使用多种口味类型的情况。协变量包括人口统计学特征、电子烟使用频率、吸烟状况、当前使用其他烟草制品以及使用电子烟的原因。
青少年中最受欢迎的电子烟口味是水果、糖果和其他口味；年轻成年人中最受欢迎的是水果、糖果和薄荷/薄荷醇口味；而在老年成年人中则是烟草或其他口味、水果和薄荷/薄荷醇口味。与老年成年人相比，青少年和年轻成年人更有可能使用水果味电子烟（调整后的优势比[aOR] = 3.35；95%置信区间[CI]，2.56-4.38；aOR = 2.31；95% CI，1.77-3.01）和糖果味电子烟（aOR = 3.81；95% CI，2.74-5.28；aOR = 2.95；95% CI，2.29-3.80），并且同时使用多种口味类型（aOR = 4.58；95% CI，3.39-6.17；aOR = 2.28；95% CI，1.78-2.91）。
对甜味电子烟口味（如水果和糖果味）的监管可能有助于减少年轻人使用电子烟的情况，而不会对成年电子烟使用者造成实质性负担。
