The National Cancer Institute has concluded that exposure to smoking in movies causes adolescent smoking and there are similar results for young adults.
This study investigated whether exposure of young adult smokers to images of smoking in films stimulated smoking behavior.
100 cigarette smokers aged 18-25 years were randomly assigned to watch a movie montage composed with or without smoking scenes and paraphernalia followed by a 10-minute recess. The outcome was whether or not participants smoked during the recess. Data were collected and analyzed in 2008 and 2009.
Smokers who watched the smoking scenes were more likely to smoke during the break (OR=3.06, 95% CI=1.01, 9.29). In addition to this acute effect of exposure, smokers who had seen more smoking in movies before the day of the experiment were more likely to smoke during the break (OR=6.73, 95% CI=1.00, 45.25, comparing the top to bottom 5th percentiles of exposure). Level of nicotine dependence (OR=1.71, 95% CI=1.27, 2.32 per point on the Fagerström Test for Nicotine Dependence scale); contemplation (OR=9.07, 95% CI=1.71, 47.99) and precontemplation (OR=7.30, 95% CI=1.39, 38.36) stages of change; and impulsivity (OR=1.21, 95% CI=1.03, 1.43) were also associated with smoking during the break. Participants who watched the montage with smoking scenes and those with a higher level of nicotine dependence were also more likely to have smoked within 30 minutes after the study.
There is a direct link between viewing smoking scenes and immediate subsequent smoking behavior. This finding suggests that individuals attempting to limit or quit smoking should be advised to refrain from or reduce their exposure to movies that contain smoking.
美国国家癌症研究所得出结论,电影中出现吸烟镜头会导致青少年吸烟,而对于年轻人来说也有类似的结果。
本研究旨在调查年轻成年吸烟者观看电影中的吸烟镜头是否会刺激吸烟行为。
将 100 名年龄在 18-25 岁的吸烟参与者随机分为两组,一组观看包含吸烟场景和吸烟用具的电影蒙太奇片段,另一组观看不包含吸烟场景和用具的电影蒙太奇片段,两组观看结束后均有 10 分钟的休息时间。研究的结果是参与者在休息时间是否吸烟。数据于 2008 年和 2009 年收集和分析。
观看吸烟场景的吸烟者在休息时间更有可能吸烟(OR=3.06,95%CI=1.01,9.29)。除了这种暴露的急性影响之外,在实验当天之前看过更多电影中吸烟镜头的吸烟者在休息时间更有可能吸烟(OR=6.73,95%CI=1.00,45.25,比较暴露的前 5%和后 5%)。尼古丁依赖程度(OR=1.71,95%CI=1.27,2.32,每点尼古丁依赖程度量表(Fagerström 测试);思考(OR=9.07,95%CI=1.71,47.99)和前思考(OR=7.30,95%CI=1.39,38.36)改变阶段;以及冲动性(OR=1.21,95%CI=1.03,1.43)也与休息时间吸烟有关。观看有吸烟场景的蒙太奇片段的参与者和尼古丁依赖程度较高的参与者在研究结束后 30 分钟内也更有可能吸烟。
观看吸烟场景与随后立即吸烟行为之间存在直接联系。这一发现表明,试图限制或戒烟的个人应被告知避免或减少接触含有吸烟镜头的电影。
