目标。 2000年初，美国遗产基金会发起了全国“真相”运动，这是第一个旨在阻止青少年吸烟的全国性反吸烟运动。我们研究了该运动对美国青少年（8、10 和 12 年级学生）全国吸烟率的影响。方法。我们使用了前/后准实验设计中的“监测未来”调查的数据，将青少年吸烟流行率的趋势与不同剂量的“真相”活动联系起来，该活动以全国约 50000 名 8、10 和 12 年级学生为样本，从 1997 年到 2002 年每年春天进行调查。结果。调查结果表明，这项运动在近期青少年吸烟率下降的过程中发挥了重要作用。我们发现，1999 年至 2002 年间，所有学生的吸烟率从 25.3% 下降到 18.0%，而这项运动约占这一下降的 22%。结论。这项研究表明，该运动与青少年吸烟率大幅下降有关，并加速了近期青少年吸烟率的下降。
Objectives. In early 2000, the American Legacy Foundation launched the national "truth" campaign, the first national antismoking campaign to discourage tobacco use among youths. We studied the impact of the campaign on national smoking rates among US youths (students in grades 8, 10, and 12).Methods. We used data from the Monitoring the Future survey in a pre/post quasi-experimental design to relate trends in youth smoking prevalence to varied doses of the "truth" campaign in a national sample of approximately 50000 students in grades 8, 10, and 12, surveyed each spring from 1997 through 2002.Results. Findings indicate that the campaign accounted for a significant portion of the recent decline in youth smoking prevalence. We found that smoking prevalence among all students declined from 25.3% to 18.0% between 1999 and 2002 and that the campaign accounted for approximately 22% of this decline.Conclusions. This study showed that the campaign was associated with substantial declines in youth smoking and has accelerated recent declines in youth smoking prevalence.
