Movie Influence on Adolescent Smoking: A Follow-up Study

描述(申请人提供)：背景：在先前的一项前瞻性研究中，我们发现，即使在调整了其他社会影响、儿童和父母特征后，观看电影中的吸烟对10至14岁的青少年开始吸烟也有很强的预测作用。我们现在建议继续跟踪这群青少年。目的：本研究的主要目的是评估在电影中观看吸烟对成为吸烟者的风险的影响，评估年龄对电影吸烟暴露与吸烟开始之间的关系的影响，并确定可能改变电影吸烟暴露与青少年吸烟行为之间的关系的儿童和父母因素。方法：为了实现这些目标，我们对2603名参加我们先前前瞻性研究的青少年进行了一项为期三年的纵向电话调查。这些青少年现在15到19岁。参与者将每年接受调查，以更新他们的吸烟状况、电影曝光和其他吸烟风险因素。与我们之前的研究一样，调查将使用CATI系统进行管理，每个单独的调查将包含一个独特的电影子集，从票房最高的热门影片和视频租赁的更大样本中随机选择。调查答复将与电影中吸烟内容分析的信息联系起来，以估计个人对电影吸烟的暴露程度。意义：这些青少年现在正处于吸烟风险最高的年龄。建议的后续行动的最佳时机是评估电影对青春期后期开始吸烟的影响和对已建立的吸烟的影响。我们之前对这一群体的研究产生了非常重要的发现，促进了州总检察长和电影行业代表之间的对话。这项拟议的研究结果将通过澄清电影吸烟暴露对老年开始吸烟的风险的影响，以及更重要的是，对发展为已建立的吸烟的影响，从而扩展我们早期的发现。

DESCRIPTION (provided by applicant): Background: In a previous prospective study, we found that viewing smoking in movies strongly predicted smoking initiation among adolescents 10 to 14 years of age, even after adjusting for other social influences, child and parenting characteristics. We now propose to continue following this cohort of adolescents. Aims: The primary aims of this study are to evaluate the effect of viewing smoking in movies on the risk of becoming an established smoker, evaluate the impact of age on the relationship between movie smoking exposure and smoking initiation, and identify child and parenting factors that may modify the association between exposure to movie smoking and adolescent smoking behavior Methods: To accomplish these aims, we propose a three-year longitudinal telephone survey of the 2603 adolescents who participated in our previous prospective study. These adolescents are now 15 to 19 years of age. Participants will be surveyed annually to update their smoking status, movie exposure, and other risk factors for smoking. As in our previous study, surveys will be administered using a CATI system and each individual survey will contain a unique subset of movies, randomly selected from a larger sample of top box office hits and video rentals. Survey responses will be linked with information from a content analysis of smoking in movies to estimate an individual's exposure to movie smoking. Significance: These adolescents are now at the age of highest risk for smoking uptake. The proposed follow-up is optimally timed to evaluate the influence of movies on smoking initiation in late adolescence and on established smoking. Our previous study of this cohort produced highly significant findings that catalyzed a dialogue between State Attorneys General and representatives from the motion picture industry. Results from the proposed study will extend our earlier findings by clarifying the influence of movie smoking exposure on risk of later age smoking initiation and, importantly, on progression to established smoking.
