The aim of this study was to assess film character portrayals of tobacco and alcohol use in US and nationally-produced films that were popular in Argentina and Mexico from 2004-2012. We performed a content analysis of these films (n=82 Argentine, 91 Mexican, and 908 US films, respectively). Chi-squares and t-tests were used to compare characteristics of characters who smoked or drank by country of movie production. Then data from all countries were pooled, and generalized estimating equation (GEE) models were used to determine independent correlates of character smoking or drinking. There were 480 major characters for Argentine-, 364 for Mexican-, and 4962 for US-produced films. Smoking prevalence among movie characters was similar to population smoking prevalence in Mexico (21%) and Argentina (26%), but about half in the US (11%), where movie product placements are restricted. Movie smoking declined over the period in all three countries. Movie alcohol prevalence was 40-50% across all countries and did not change with time. Demographic predictors of character smoking included: being male, 18 and older, having negative character valence. Movie smoking was not associated with lower SES. Predictors of character drinking included: being age 18 and older and positive character valence. Smoking and drinking predicted each other, illicit drug use, and higher scores for other risk behaviors. This suggests that policy development in Mexico and Argentina may be necessary to reduce the amount of character tobacco and alcohol use in films.
本研究旨在评估2004年至2012年在美国以及在阿根廷和墨西哥流行的国产电影中烟草和酒精使用的电影角色刻画。我们对这些电影进行了内容分析（分别为82部阿根廷电影、91部墨西哥电影和908部美国电影）。使用卡方检验和t检验来比较按电影制作国家划分的吸烟或饮酒角色的特征。然后将所有国家的数据汇总，并使用广义估计方程（GEE）模型来确定角色吸烟或饮酒的独立相关因素。阿根廷制作的电影中有480个主要角色，墨西哥制作的电影中有364个，美国制作的电影中有4962个。电影角色中的吸烟率与墨西哥（21%）和阿根廷（26%）的人口吸烟率相似，但在美国（11%）约为一半，美国对电影产品植入有限制。在这三个国家中，电影中的吸烟现象在这一时期都有所下降。所有国家的电影酒精使用率为40%-50%，且没有随时间变化。角色吸烟的人口统计学预测因素包括：男性、18岁及以上、具有负面角色效价。电影吸烟与较低的社会经济地位无关。角色饮酒的预测因素包括：18岁及以上和正面角色效价。吸烟和饮酒相互预测、非法药物使用以及其他风险行为的得分更高。这表明墨西哥和阿根廷可能有必要制定政策，以减少电影中角色的烟草和酒精使用量。
