简介许多电子烟用户发现电子烟的多种口味很有吸引力。我们研究了青少年和成人电子烟用户样本对电子烟液口味的偏好和偏好口味总数是否存在差异。我们还分别检查了这些偏好是否与青少年或成人的电子烟使用频率相关。 材料和方法分析样本包括 1) 来自康涅狄格州 5 所高中的 396 名青少年，过去一个月的电子烟使用者，他们于 2014 年秋季完成了一项匿名、基于学校的调查（56.1% 为男性；16.18 [1.18] 岁；42.2% 过去一个月吸烟者），以及 2) 2014 年秋季，590 名过去一个月使用过电子烟的成人完成了一项匿名 MTurk 调查（53.7% 为男性；34.25 [9.89] 岁；51.2% 过去一个月吸烟者）。结果与成年人相比，更大比例的青少年更喜欢水果、酒精和“其他”口味的电子烟液，而成年人则不成比例地更喜欢烟草、薄荷醇、薄荷、咖啡和电子烟。香料味电子液体（p 值 < .05）。与青少年相比，成年人还喜欢更多的口味，并且更频繁地使用电子烟（p 值 < .001）。口味偏好与青少年样本中电子烟的使用频率独特相关。偏好的口味总数与电子烟使用天数的增加有关 (eta(2)(p) = 0.04)，对水果 (eta(2)(p) = 0.02)、甜点 (eta(2)(p) = 0.02) 和酒精味 (eta(2)(p) = 0.02) 电子烟液的偏好也与此相关。 结论 青少年和成人样本之间的口味偏好不同。虽然青少年总体上电子烟使用频率较低，但他们对特定口味的偏好和偏好口味的总数与电子烟使用天数的增加有关，这表明口味偏好可能在青少年电子烟使用中发挥重要作用。
IntroductionMany e-cigarette users find the variety of e-cigarette flavors appealing. We examined whether preferences for e-liquid flavors and the total number of flavors preferred differed between samples of adolescent and adult e-cigarette users. We also examined whether these preferences were associated with e-cigarette use frequency for adolescents or adults, respectively.Materials and methodsThe analytic samples comprised 1) 396 adolescent, past-month e-cigarette users from 5 Connecticut high schools who completed an anonymous, school-based survey in Fall 2014 (56.1% male; 16.18 [1.18] years; 42.2% past-month smokers), and 2) 590 adult, past-month e-cigarette users who completed an anonymous, MTurk survey in Fall 2014 (53.7% male; 34.25 [9.89] years; 51.2% past-month smokers).ResultsCompared to adults, a larger proportion of adolescents preferred fruit, alcohol, and "other" flavored e-liquids, whereas adults disproportionately preferred tobacco, menthol, mint, coffee, and spice-flavored e-liquids (p-values < .05). Adults also preferred a greater total number of flavors compared to adolescents and used e-cigarettes more frequently (p-values < .001). Flavor preferences uniquely were associated with frequency of e-cigarette use within the adolescent sample; the total number of flavors preferred was associated with more days of e-cigarette use (eta(2)(p) = 0.04), as were preferences for fruit (eta(2)(p) = 0.02), dessert (eta(2)(p) = 0.02), and alcohol-flavored (eta(2)(p) = 0.02) e-liquids.ConclusionsFlavor preferences differed between adolescent and adult samples. While youth reported less frequent e-cigarette use overall, their preferences for specific flavors and the total number of flavors preferred were associated with more days of e-cigarette use, indicating that flavor preferences may play an important role in adolescent e-cigarette use.
