Lesbian, gay, bisexual and transgender (LGBT) people have significantly higher smoking prevalence than heterosexual people in the U.S.A. The reasons for this disparity remain unclear. Tobacco use in movies has a substantial influence on tobacco use behaviours, particularly among youth. Yet, no research has examined tobacco use in movies for LGBT audiences or containing LGBT characters.
We identified 81 U.S. movies from 2000 to 2011 with a theatre release and with LGBT themes or characters. We then selected a random sample of these movies (n=45) for quantitative content analysis to examine the proportion of movies with depictions of tobacco use and the number of occurrences of tobacco use.
Tobacco use was depicted in 87% (95% CI 80% to 94%) of movies with an average of four occurrences of tobacco use per hour (95% CI 3 to 5). Only 15% (95% CI 8% to 23%) of movies and 3% of all depictions of tobacco use conveyed any harms of tobacco use.
Viewers of movies with LGBT themes or characters are exposed, on average, to one depiction of tobacco use for every 15 min of movie run-time. As a major component of the entertainment media environment, movies may contribute to smoking among LGBT people.
在美国,女同性恋、男同性恋、双性恋和跨性别者(LGBT)的吸烟率显著高于异性恋者。这种差异的原因尚不清楚。电影中的烟草使用对烟草使用行为有重大影响,尤其是在青少年中。然而,尚无研究调查面向LGBT观众或包含LGBT角色的电影中的烟草使用情况。
我们识别出2000年至2011年在美国影院上映的、带有LGBT主题或角色的81部电影。然后从这些电影中随机抽取样本(n = 45)进行定量内容分析,以研究呈现烟草使用的电影比例以及烟草使用的出现次数。
87%(95%置信区间80%至94%)的电影中有烟草使用的画面,平均每小时出现4次烟草使用镜头(95%置信区间3至5)。只有15%(95%置信区间8%至23%)的电影以及所有烟草使用画面的3%传达了任何烟草使用的危害。
对于带有LGBT主题或角色的电影观众而言,平均每观看15分钟电影就会看到一次烟草使用的画面。作为娱乐媒体环境的一个主要组成部分,电影可能促使LGBT人群吸烟。
