How do media campaigns and tobacco-relevant news coverage influence adolescent and adult smoking?

这项研究将把电视反吸烟广告的曝光率、烟草问题的新闻报道和其他烟草控制政策与(a) 2002年至2008年每年对2000名成年吸烟者的访谈队列和(b) 1993年至2008年每三年对青少年吸烟情况的调查（n-150,000）结合起来。分析将确定反吸烟广告和与烟草有关的新闻报道在促使吸烟者戒烟和改变青少年吸烟方面的作用。

The study will merge measures of exposure to televised anti-smoking advertising, press coverage about tobacco issues and other tobacco control policies with (a) an annually interviewed cohort of 2,000 adult smokers from 2002-2008 and (b) triennial surveys of smoking among adolescents 1993-2008 (n-150,000).
