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）：吸烟是美国成年人肺癌的主要原因，也是其他疾病死亡的重要原因。青少年时期开始吸烟。研究提供了大量的文件，社会影响的影响开始，特别是父母和同龄人的影响。9年前，我们在北方新英格兰的5000多名青少年中开始研究电影吸烟对青少年早期吸烟行为的影响，并继续对6500多名具有全国代表性的美国青少年进行纵向样本研究。我们证明并证实了接触电影吸烟和青少年吸烟开始之间的横截面关联，在从不吸烟者中，认可更积极的期望和更高水平的吸烟易感性。我们对每个队列中的从不吸烟者进行了1-2年的随访，结果显示，电影吸烟的基线暴露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。在这个竞争性的更新申请中，涵盖了从2007年5月开始的5年期，我们建议将重点转移到理解观察到的关联的过程。继续跟踪我们的国家样本的青少年谁是10-14岁的基线，我们将测试中介和适度（种族和社会风险）的假设方面开始吸烟。建议调解人包括吸烟风险原型，应对预期。此外，我们将模拟烟草依赖的途径作为持续暴露于电影吸烟的函数，检查多个吸烟依赖结构：频率/数量的措施，自主性的丧失，以及自我作为吸烟者的感知。为了实现这些目标，我们将每半年对纵向队列进行3次以上的波（波5-7），直到该组年龄在18至22岁之间。该样本将增加非裔美国青少年的数量，以更好地研究在青春期早期出现的对电影吸烟对行为影响有抵抗力的群体。这项研究提供了一个无与伦比的机会，以进一步研究暴露于电影吸烟对青少年和年轻人吸烟行为的影响的机制。由于美国电影在世界各地销售和发行，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。
