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).
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.
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.
This study showed that the campaign was associated with substantial declines in youth smoking and has accelerated recent declines in youth smoking prevalence.
2000年初，美国遗产基金会发起了全国性的“真相”运动，这是首个旨在劝阻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（八年级、十年级和十二年级学生）全国吸烟率的影响。
我们采用了“监测未来”调查的数据，运用前后准实验设计，在1997年至2002年每年春季对全国约50000名八年级、十年级和十二年级学生进行调查的样本中，将青少年吸烟流行趋势与不同强度的“真相”运动联系起来。
研究结果表明，该运动在近期青少年吸烟流行率下降中占了很大比例。我们发现，1999年至2002年间，所有学生的吸烟流行率从25.3%降至18.0%，该运动约占这一下降幅度的22%。
本研究表明，该运动与青少年吸烟率的大幅下降相关，并加速了近期青少年吸烟流行率的下降。
