This study examines smoke-free youth partnerships implementing the Teens Against Tobacco Use model developed by the American Lung Association. This innovative tobacco prevention strategy has not been evaluated rigorously. Students used peer teaching to educate youth about tobacco use and engaged in tobacco control advocacy activities. Participating high school and middle school youth were trained to develop and deliver tobacco prevention presentations to 4th-8th grade students in schools.
To evaluate the efficacy of the presentations, matched pairs of classrooms willing to have 1 presentation were randomly assigned to receive either the presentation first (intervention condition) or later in the school year (control condition).
SETTING/PARTICIPANTS: The study took place in a predominantly low-income Hispanic community. A total of 9 schools, 107 classes, and 2,257 students participated in the evaluation.
Tobacco susceptibility was assessed with a brief survey administered to students in both intervention and control classrooms in 2014 and 2015 after the completion of presentations in intervention classrooms. Analyses completed in 2019 compared intervention and control classrooms on tobacco susceptibility.
Intent-to-treat analyses indicated that classrooms receiving a tobacco prevention presentation had significantly lower tobacco susceptibility scores than classrooms that did not receive a presentation (12% vs 17%, p<0.01), representing a 37% reduction in the odds of tobacco susceptibility. Teens Against Tobacco Use presenters also completed tobacco retailer compliance checks and gained media coverage in advocating to regulate e-cigarettes in the same manner as other tobacco products.
Findings suggest Teens Against Tobacco Use is an effective means of reducing tobacco susceptibility among 4th-8th graders in the immediate term. Longer-term outcome evaluations are needed to determine whether Teens Against Tobacco Use presentations can have a lasting impact on tobacco use.

本研究考察了实施美国肺协会青少年禁烟伙伴关系（Teens Against Tobacco Use）模式的无烟青少年伙伴关系。这种创新的烟草预防策略尚未经过严格评估。学生使用同伴教学向青少年传授有关烟草使用的知识，并参与烟草控制宣传活动。参与的高中生和初中生接受培训，以向学校的 4 至 8 年级学生开发和提供烟草预防演讲。
为了评估演示的效果，愿意接受 1 次演示的配对教室被随机分配接受演示（干预条件）或在学年后期接受演示（对照条件）。
地点/参与者：该研究在一个以低收入西班牙裔为主的社区进行。共有 9 所学校、107 个班级和 2257 名学生参与了评估。
在干预教室完成演示后，于 2014 年和 2015 年，向干预和对照教室的学生发放简短问卷评估烟草易感性。2019 年完成的分析比较了接受和未接受烟草预防演示的教室的烟草易感性。
意向治疗分析表明，接受烟草预防演示的教室的烟草易感性评分明显低于未接受演示的教室（12%比 17%，p<0.01），表明烟草易感性的几率降低了 37%。青少年反烟草使用演讲者还完成了烟草零售商合规检查，并获得媒体报道，倡导以与其他烟草产品相同的方式监管电子烟。
研究结果表明，青少年反烟草使用是在短期内减少 4 至 8 年级学生烟草易感性的有效手段。需要进行更长期的结果评估，以确定青少年反烟草使用演示是否对烟草使用产生持久影响。
