Compared to adolescents with low exposure to smoking in movies, those with high exposure are about three times as likely to try smoking or become smokers. We have observed this effect in nationally representative samples using cross-sectional and longitudinal designs. This effect remains statistically significant after controlling for numerous other traditional risk factors, such as personality, parenting style, and sociodemographics. Indeed, the movie-smoking exposure effect on adolescent smoking initiation is greatest among those traditionally considered at lower risk for smoking, such as those low in sensation seeking and those whose parents do not smoke. In this article, we consider possible moderators and mediators of this important media effect as well as health-policy implications. The take-home message is that eliminating smoking in movies may prevent a substantial number of adolescents from smoking.
与电影中吸烟镜头曝光率低的青少年相比，曝光率高的青少年尝试吸烟或成为烟民的可能性大约是前者的三倍。我们通过横断面研究和纵向研究设计，在具有全国代表性的样本中观察到了这种效应。在控制了众多其他传统风险因素（如性格、养育方式和社会人口统计学因素）之后，这种效应在统计学上仍然显著。事实上，电影吸烟镜头曝光对青少年吸烟起始的影响在那些传统上被认为吸烟风险较低的人群中最为显著，比如那些寻求刺激程度较低以及父母不吸烟的青少年。在本文中，我们探讨了这一重要媒体效应可能的调节因素和中介因素，以及对健康政策的启示。关键信息是，消除电影中的吸烟镜头可能会阻止大量青少年吸烟。
