Description of adolescent e-cigarette use over time.
In 2017 and 2019, 261 adolescents from North Rhine-Westphalia who had used e-cigarettes at least once a month (mean age: 14.9 years; 33.5 % female) took part in a questionnaire study.
In 2017, 84 adolescents (32.2 %) reported exclusive e-cigarette use (single users), 177 adolescents were classified as dual users (67.8 %) because they consumed a tobacco product (conventional cigarette and/or hookah) in addition to e-cigarettes. During the observation period of 18 months, 83 adolescents (31.8 %) quit nicotine products altogether. Dual users quit nicotine less often than single users (N = 39 or 22.0 % vs. N = 44 or 52.4 %, p < 0.001). Seven single users (8.3 %) did not change their behavior, 11 began to use tobacco exclusively (13.1 %), another 22 (26.2 %) started dual use. Seventy-eight dual users (44.1 %) did not change their behavior, 57 (32.1 %) switched to tobacco use only, 3 dual users (1.7 %) stopped tobacco use, but continued to use e-cigarettes. Taken together, at the end of the study, 10 (5.6 %) of the remaining 178 adolescents consumed only e-cigarettes, while 168 (94.4 %) smoked tobacco or were dual-users.
More than two thirds of all young e-cigarette users and more than three quarters of dual users also used nicotine products 18 months later. The remaining consumers showed a less frequent stay or switch to single use, instead a more frequent use of tobacco or dual use.
描述青少年电子烟使用情况随时间的变化。
2017年和2019年,来自北莱茵 - 威斯特法伦州的261名每月至少使用一次电子烟的青少年(平均年龄:14.9岁;33.5%为女性)参与了一项问卷调查研究。
2017年,84名青少年(32.2%)报告仅使用电子烟(单一使用者),177名青少年被归类为双重使用者(67.8%),因为他们除了使用电子烟外还消费烟草制品(传统香烟和/或水烟)。在18个月的观察期内,83名青少年(31.8%)完全戒掉了尼古丁产品。双重使用者戒掉尼古丁的频率低于单一使用者(分别为39名或22.0% 与44名或52.4%,p < 0.001)。7名单一使用者(8.3%)未改变其行为,11名开始仅使用烟草(13.1%),另外22名(26.2%)开始双重使用。78名双重使用者(44.1%)未改变其行为,57名(32.1%)仅转向使用烟草,3名双重使用者(1.7%)停止使用烟草,但继续使用电子烟。总体而言,在研究结束时,其余178名青少年中有10名(5.6%)仅消费电子烟,而168名(94.4%)吸烟或为双重使用者。
所有年轻电子烟使用者中超过三分之二以及超过四分之三的双重使用者在18个月后仍使用尼古丁产品。其余使用者较少保持或转向单一使用,而是更频繁地使用烟草或双重使用。
