The Surgeon General has concluded that there is a causal relationship between depictions of smoking in the movies and the initiation of smoking among young persons (1). The more youths see smoking on screen, the more likely they are to start smoking; youths who are heavily exposed to onscreen smoking imagery are approximately two to three times as likely to begin smoking as are youths who receive less exposure (1,2). A Healthy People 2020 objective is to reduce the proportion of youths exposed to onscreen tobacco marketing in movies and television (Tobacco Use Objective 18.3) (3). To assess the recent extent of tobacco use imagery in youth-rated movies (G, PG, PG-13*), 2010-2016 data from Thumbs Up! Thumbs Down! (TUTD), a project of Breathe California of Sacramento-Emigrant Trails were analyzed and compared with previous reports. In 2016, 41% of movies that were among the 10 top-grossing movies in any calendar week included tobacco use, compared with 45% in 2010. Among youth-rated movies, 26% included tobacco use in 2016 (including 35% of PG-13 movies) compared with 31% in 2010 (including 43% of PG-13 movies). The steady decline in the number of tobacco incidents in youth-rated movies from 2005-2010 stopped after 2010. The total number of individual occurrences of tobacco use in a movie (tobacco incidents) in top-grossing movies increased 72%, from 1,824 in 2010 to 3,145 in 2016, with an increase of 43% (from 564 to 809) occurring among PG-13 rated movies. Reducing tobacco use in youth-related movies could help prevent the initiation of tobacco use among young persons.
美国卫生局局长得出结论,电影中对吸烟的描绘与年轻人开始吸烟之间存在因果关系(1)。年轻人在屏幕上看到吸烟的场景越多,就越有可能开始吸烟;大量接触屏幕上吸烟画面的年轻人开始吸烟的可能性大约是接触较少的年轻人的两到三倍(1,2)。《健康人民2020》的一个目标是减少年轻人接触电影和电视中屏幕烟草营销的比例(烟草使用目标18.3)(3)。为了评估青少年分级电影(G级、PG级、PG - 13级*)中近期烟草使用画面的程度,对萨克拉门托 - 移民小径呼吸加州组织的一个项目“点赞!差评!”(TUTD)2010 - 2016年的数据进行了分析,并与之前的报告进行了比较。2016年,在任何日历周票房排名前十的电影中,41%的电影包含烟草使用场景,而2010年这一比例为45%。在青少年分级电影中,2016年有26%包含烟草使用场景(包括35%的PG - 13级电影),而2010年为31%(包括43%的PG - 13级电影)。2010年后,2005 - 2010年青少年分级电影中烟草出现次数的稳步下降趋势停止了。票房排名靠前的电影中一部电影里烟草使用的个体出现总数(烟草出现次数)增加了72%,从2010年的1824次增加到2016年的3145次,其中PG - 13级电影增加了43%(从564次增加到809次)。减少与青少年相关电影中的烟草使用有助于预防年轻人开始使用烟草。
