Objective.区域性研究将接触电影吸烟与青少年吸烟联系起来。我们在一个有代表性的美国样本中研究了这种关联。我们对6522名10至14岁的美国青少年进行了随机数字拨号调查。使用以前验证的方法，我们估计暴露于电影吸烟，在532最近的票房命中，并检查其与青少年曾经尝试吸烟的香烟。未加权样本中的人口统计和人口普查区域分布与2000年美国人口普查估计几乎相同，证实了代表性。总的来说，10%的人尝试过吸烟。电影吸烟暴露的四分位数（Q）与开始吸烟的患病率显著相关：Q1中0.02的青少年尝试过吸烟; Q2中0.06; Q3中0.11; Q4中0.22。这种关联在种族/民族或人口普查地区之间没有显著差异。在控制了社会人口统计学、朋友/兄弟姐妹/父母吸烟、学校表现、人格特征和父母教养方式后，尝试吸烟的调整优势比为1.7（95%置信区间[CI]：1.1，2.7），Q3为1.8（95% CI：1.2，2.9），Q4为2.6（95% CI：1.7，4.1）。协变量调整的归因分数为0.38（95%CI：0.20，0.56），表明接触电影吸烟是该年龄组美国青少年开始吸烟的主要独立危险因素。电影中的吸烟是美国青少年开始吸烟的危险因素。限制青少年接触电影吸烟可能会对公共卫生产生重要影响。
Objective. Regional studies have linked exposure to movie smoking with adolescent smoking. We examined this association in a representative US sample.Design/Methods. We conducted a random-digit-dial survey of 6522 US adolescents aged 10 to 14 years. Using previously validated methods, we estimated exposure to movie smoking, in 532 recent box-office hits, and examined its relation with adolescents having ever tried smoking a cigarette.Results. The distributions of demographics and census region in the unweighted sample were almost identical to 2000 US Census estimates, confirming representativeness. Overall, 10% of the population had tried smoking. Quartile ( Q) of movie smoking exposure was significantly associated with the prevalence of smoking initiation: 0.02 of adolescents in Q1 had tried smoking; 0.06 in Q2; 0.11 in Q3; and 0.22 in Q4. This association did not differ significantly by race/ethnicity or census region. After controlling for sociodemographics, friend/sibling/parent smoking, school performance, personality characteristics, and parenting style, the adjusted odds ratio for having tried smoking were 1.7 (95% confidence interval [CI]: 1.1, 2.7) for Q2, 1.8 ( 95% CI: 1.2, 2.9) for Q3, and 2.6 ( 95% CI: 1.7, 4.1) for Q4 compared with adolescents in Q1. The covariate-adjusted attributable fraction was 0.38 ( 95% CI: 0.20, 0.56), suggesting that exposure to movie smoking is the primary independent risk factor for smoking initiation in US adolescents in this age group.Conclusions. Smoking in movies is a risk factor for smoking initiation among US adolescents. Limiting exposure of young adolescents to movie smoking could have important public health implications.
