To investigate the hypothesis that exposure to alcohol consumption in movies affects the likelihood that low-risk adolescents will start to drink alcohol.
Longitudinal study of 2346 adolescent never drinkers who also reported at baseline intent to not to do so in the next 12 months (mean age 12.9 years, SD = 1.08). Recruitment was carried out in 2009 and 2010 in 112 state-funded schools in Germany, Iceland, Italy, Netherlands, Poland, and Scotland. Exposure to movie alcohol consumption was estimated from 250 top-grossing movies in each country in the years 2004 to 2009. Multilevel mixed-effects Poisson regressions assessed the relationship between baseline exposure to movie alcohol consumption and initiation of trying alcohol, and binge drinking (≥ 5 consecutive drinks) at follow-up.
Overall, 40% of the sample initiated alcohol use and 6% initiated binge drinking by follow-up. Estimated mean exposure to movie alcohol consumption was 3653 (SD = 2448) occurrences. After age, gender, family affluence, school performance, TV screen time, personality characteristics, and drinking behavior of peers, parents, and siblings were controlled for, exposure to each additional 1000 movie alcohol occurrences was significantly associated with increased relative risk for trying alcohol, incidence rate ratio = 1.05 (95% confidence interval, 1.02-1.08; P = .003), and for binge drinking, incidence rate ratio = 1.13 (95% confidence interval, 1.06-1.20; P < .001).
Seeing alcohol depictions in movies is an independent predictor of drinking initiation, particularly for more risky patterns of drinking. This result was shown in a heterogeneous sample of European youths who had a low affinity for drinking alcohol at the time of exposure.
研究假设即电影中饮酒场景的暴露会影响低风险青少年开始饮酒的可能性。
对 2346 名从未饮酒的青少年进行纵向研究，这些青少年在基线时报告称在接下来的 12 个月内没有饮酒意向（平均年龄 12.9 岁，标准差=1.08）。招募工作于 2009 年至 2010 年在德国、冰岛、意大利、荷兰、波兰和苏格兰的 112 所公立学校进行。使用 2004 年至 2009 年期间各国票房最高的 250 部电影来评估电影中酒精摄入的暴露量。采用多层混合效应泊松回归评估基线时电影中酒精摄入的暴露与随访时开始尝试饮酒和 binge drinking（≥5 连续饮酒）之间的关系。
总体而言，40%的样本在随访时开始饮酒，6%的样本开始 binge drinking。估计的电影中酒精摄入的平均暴露量为 3653（SD=2448）次。在控制年龄、性别、家庭富裕程度、学业成绩、电视屏幕时间、人格特征以及同伴、父母和兄弟姐妹的饮酒行为后，每额外暴露 1000 次电影中的酒精摄入与尝试饮酒的相对风险增加显著相关，发生率比=1.05（95%置信区间，1.02-1.08；P=0.003），与 binge drinking 的发生率比=1.13（95%置信区间，1.06-1.20；P<0.001）。
在电影中看到饮酒描绘是饮酒开始的独立预测因素，特别是对于更危险的饮酒模式。这一结果在一组具有低酒精亲和力的欧洲青少年异质样本中得到了证实。
