吸烟在电影中很普遍。然而，在这方面，使用内容分析来描述电影中吸烟的趋势提供了混合的结果，并没有挖掘青少年实际感知的内容。为了评估青少年感知的电影中吸烟流行率的未来趋势，并确定与这些趋势相关的预测因素。2006年，当参与者年龄在12岁至18岁之间（N=4735）时，采用潜变量增长模型，使用四级量表来描述电影中吸烟流行率的纵向趋势（绝大多数情况下）每6个月测量一次，并检查这些趋势与人口统计学，吸烟相关态度和社会环境预测因素之间的关联。分析是在2009年进行的。在基线时，大约50%的参与者报告说在电影中看到吸烟的一些时间，另有36%的人报告说大部分时间。青少年认为电影中吸烟的流行率随着时间的推移而下降，14-16岁的青少年中的下降幅度大于基线时年龄较小的青少年（p≤0.05）。尽管吸烟率有所下降，但青少年仍报告说，他们有时会在电影中看到吸烟。青少年谁报告更多的亲密朋友吸烟也报告了较高的患病率在电影中吸烟在基线（回归系数=0.04-0.18，p<0.01）。尽管有所下降，但青少年仍然接触到适量的吸烟图像。可能需要采取干预措施，进一步减少青少年在电影中接触吸烟，以影响青少年吸烟。
BACKGROUNDSmoking in movies is prevalent. However, use of content analysis to describe trends in smoking in movies has provided mixed results and has not tapped what adolescents actually perceive.PURPOSETo assess the prospective trends in the prevalence of smoking in movies as perceived by teenagers and identify predictors associated with these trends.METHODSUsing data from the Minnesota Adolescent Community Cohort Study collected during 2000–2006 when participants were aged between 12 and 18 years (N=4735), latent variable growth models were employed to describe the longitudinal trends in the perceived prevalence of smoking in movies using a four-level scale (never to most of the time) measured every 6 months, and examined associations between these trends and demographic, smoking-related attitudinal and socio-environmental predictors. Analysis was conducted in 2009.RESULTSAt baseline, about 50% of participants reported seeing smoking in movies some of the time, and another 36% reported most of the time. The prevalence of smoking in movies as perceived by teenagers declined over time, and the decline was steeper in those who were aged 14–16 years than those who were younger at baseline (p≤0.05). Despite the decline, teenagers still reported seeing smoking in movies some of the time. Teenagers who reported more close friends who smoked also reported a higher prevalence of smoking in movies at baseline (regression coefficients=0.04–0.18, p<0.01).CONCLUSIONSTeenagers' perception of the prevalence of smoking in movies declined over time, which may be attributable to changes made by the movie industry. Despite the decline, teenagers were still exposed to a moderate amount of smoking imagery. Interventions that further reduce teenage exposure to smoking in movies may be needed to have an effect on adolescent smoking.
