Abstract：
UNASSIGNED: Alcohol is the most frequently depicted substance in the media, and adolescent exposure to alcohol in the media predicts alcohol use. There is relatively little research on exposure to cannabis in the media, but exposure to alcohol content may exert cross-substance effects on cannabis use. Given the social and health risks associated with early cannabis use, the present study aims to assess the cross-substance effects of exposure to alcohol media content on age of cannabis initiation.
UNASSIGNED: A sample of 830 middle school students (53% female) reported on movie alcohol exposure and cannabis initiation longitudinally until high school completion. Discrete-time survival models examined whether movie alcohol exposure predicted subsequent initiation among students who were cannabis-naïve at baseline, controlling for demographic, social, and behavioral covariates. The interaction between sex and movie alcohol exposure was also explored.
UNASSIGNED: One third (33%) of participants reported cannabis initiation with a mean of 5.57 estimated hours (SD = 4.29) of movie alcohol exposure. A 1-hour increase in movie exposure predicted a significant 16% increased probability of cannabis initiation in models adjusted for demographic variables and a significant 14% increase in models adjusted for demographic, behavioral, and social variables. No differences were observed across sex.
UNASSIGNED: Greater adolescent exposure to alcohol content in the media was associated with earlier cannabis initiation above and beyond other etiologically relevant demographic, behavioral, and social variables. The influence of cross-substance media exposures warrants further exploration and should be taken into consideration in the development of preventive interventions for youth substance use.

摘要：
■酒精是媒体中最常见的物质，青少年在媒体上接触酒精可以预测酒精的使用。媒体上关于接触大麻的研究相对较少，但是接触酒精含量可能会对大麻的使用产生交叉物质影响。鉴于与早期使用大麻相关的社会和健康风险，本研究旨在评估酒精介质含量对大麻起始年龄的交叉物质影响。
■830名中学生（53％为女性）的样本报告了电影酒精暴露和大麻的纵向开始，直到高中毕业。离散时间生存模型检查了电影酒精暴露是否预测了基线时未使用大麻的学生的后续启动，控制人口统计，社会,和行为协变量。还探讨了性与电影酒精暴露之间的相互作用。
■三分之一（33％）的参与者报告了大麻的开始，平均电影酒精暴露时间为5.57小时（SD=4.29）。电影曝光量增加1小时，预测在人口统计变量调整后的模型中大麻起始概率显着增加16％，在人口统计调整后的模型中大麻起始概率显着增加14％。行为，社会变量。没有观察到跨性别的差异。
■青少年更多地接触媒体中的酒精含量与较早开始使用大麻有关，超出了其他病因学相关的人口统计学，行为，社会变量。跨物质介质暴露的影响值得进一步探索，在制定青少年物质使用的预防性干预措施时应予以考虑。
