Educational programs are needed to combat the sharp rise in adolescent e-cigarette use. We assessed adolescent knowledge about e-cigarettes, perceptions of harmfulness and addictiveness and intent to try e-cigarettes before and after an e-cigarette educational session.
We conducted a one-group pre- and post-test study among middle and high school students in Alabama in 2019. The intervention included a 30-minute educational session based on the Stanford Tobacco Prevention Toolkit on e-cigarette types, contents, marketing and advertising, health effects and nicotine addiction. McNemar tests of paired proportions and multi-level, mixed-effects logistic regression models were used to analyze intervention effects.
Surveys were completed by 2,889 middle and high school students. The intervention was associated with significantly increased knowledge about e-cigarettes and perceptions that e-cigarettes are harmful and addictive, and with significantly lower intent to try e-cigarettes. At pre-test, middle school students had lower knowledge, believed that e-cigarettes were not as addictive and showed higher intent to try both e-cigarettes and cigarettes compared to high school students. Groups that were associated with lower perceived harmfulness and addictiveness were: ever-users of e-cigarettes, ever-users of both e-cigarettes and cigarettes and prior users of mint/menthol flavored e-cigarettes.
A school-based educational session was significantly associated with improved adolescent knowledge about e-cigarettes, increased the perceived harmfulness and addictiveness of e-cigarettes, and reduced intent to try e-cigarettes. E-cigarette education should be prioritized for middle school students due to lower levels of knowledge and higher intent to try tobacco compared to high school students.
需要开展教育项目来应对青少年电子烟使用率的急剧上升。我们评估了青少年对电子烟的了解程度、对电子烟危害性和成瘾性的认知,以及在电子烟教育课程前后尝试电子烟的意愿。
我们于 2019 年在阿拉巴马州的中学和高中开展了一项单组前后测试研究。干预措施包括根据斯坦福烟草预防工具包,开展时长 30 分钟的电子烟教育课程,内容包括电子烟类型、成分、营销和广告、健康影响以及尼古丁成瘾。采用配对比例 McNemar 检验和多水平混合效应逻辑回归模型分析干预效果。
共完成了 2889 名中学和高中生的问卷调查。干预措施与电子烟知识的显著增加、对电子烟危害性和成瘾性的认知的显著提高以及尝试电子烟意愿的显著降低有关。在测试前,与高中生相比,初中生电子烟知识较低,认为电子烟成瘾性较低,尝试电子烟和香烟的意愿较高。与较低的感知危害性和成瘾性相关的群体是:电子烟使用者、电子烟和香烟同时使用者,以及薄荷/ Menthol 口味电子烟的既往使用者。
基于学校的教育课程与青少年对电子烟知识的提高、增加对电子烟危害性和成瘾性的认识以及降低尝试电子烟的意愿显著相关。由于与高中相比,初中生的电子烟知识水平较低,尝试烟草的意愿较高,因此应优先对初中生进行电子烟教育。
