DESCRIPTION (provided by applicant): Smoking is the primary cause of lung cancer in US adults, and also an important cause of mortality from other conditions. Onset of smoking occurs during adolescence. Research provides extensive documentation of social influence effects on initiation, especially influence of parents and peers. We began studying the impact of movie smoking on early adolescent smoking behavior nine years ago in a sample of over 5000 Northern New England adolescents, and have continued the research with a longitudinal sample of over 6500 nationally representative US adolescents. We demonstrated and confirmed a cross-sectional association between exposure to movie smoking and adolescent smoking initiation and, among never smokers, endorsement of more positive expectancies and higher levels of susceptibility to smoking. We have followed up never-smokers in each cohort 1-2 years later, showing that baseline exposure to movie smoking predicted onset of smoking in the future, emphasizing controlling for confounding, and including up to 21 covariates in the most recent study. In this competing renewal application, covering the 5-year period beginning May 2007, we propose to shift our emphasis to understanding the process for the observed association. Continuing to follow our national sample of adolescents who were 10-14 years at baseline, we will test mediation and moderation (race and social risk) hypotheses with respect to smoking initiation. Proposed mediators include smoking risk prototypes, and coping expectancies. Additionally, we will model pathways to tobacco dependence as a function of ongoing exposure to movie smoking, examining multiple smoking dependence constructs: frequency/quantity measures, loss of autonomy, and perception of self as a smoker. To accomplish these goals, we will follow our longitudinal cohort biannually for 3 more waves (waves 5-7), until the group is 18 to 22 years of age. The sample will be enriched with African-American adolescents, to better study a group that appears in early adolescence to be resistant to the movie smoking effect on behavior. This study provides an unsurpassed opportunity to further investigate the mechanisms underlying the effect of exposure to movie smoking on smoking behavior in adolescents and young adults. Because U.S. movies are marketed and distributed all over the world, this research could have far-reaching public health implications for adolescents everywhere.

描述（由申请人提供）：吸烟是美国成年人患肺癌的主要原因，也是其他疾病导致死亡的重要原因。吸烟发生在青春期。研究提供了关于社会影响对启蒙影响的广泛记录，尤其是父母和同龄人的影响。九年前，我们开始以超过 5000 名新英格兰北部青少年为样本，研究电影吸烟对青少年早期吸烟行为的影响，并继续以超过 6500 名具有全国代表性的美国青少年为样本进行纵向研究。我们证明并证实了接触电影吸烟与青少年开始吸烟之间的横断面关联，并且在从不吸烟的人中，认可更积极的期望和更高水平的吸烟易感性。 1-2 年后，我们对每个队列中从不吸烟的人进行了随访，结果表明，基线接触电影吸烟可预测未来吸烟的发生，强调控制混杂因素，并在最近的研究中包括多达 21 个协变量。在这个竞争性更新申请中，涵盖从 2007 年 5 月开始的 5 年期间，我们建议将重点转移到了解所观察到的关联的过程上。我们将继续跟踪全国 10-14 岁青少年样本，测试关于开始吸烟的中介和适度（种族和社会风险）假设。提议的中介因素包括吸烟风险原型和应对预期。此外，我们将把烟草依赖的途径建模为持续接触电影吸烟的函数，检查多种吸烟依赖结构：频率/数量测量、自主权丧失以及对吸烟者的自我认知。为了实现这些目标，我们将每半年跟踪纵向队列 3 波（第 5-7 波），直到该群体的年龄达到 18 至 22 岁。该样本将包含非裔美国青少年，以更好地研究青春期早期对电影吸烟对行为的影响表现出抵抗力的群体。这项研究为进一步研究电影吸烟对青少年和年轻人吸烟行为影响的机制提供了绝佳的机会。由于美国电影在世界各地营销和发行，这项研究可能对世界各地的青少年产生深远的公共卫生影响。
