摘要

目的:酒精是媒体最常描述的物质,青少年接触媒体中的酒精可预测酒精的使用。关于在媒体中接触大麻的研究相对较少,但接触酒精内容可能会对大麻的使用产生交叉物质效应。鉴于过早吸食大麻所带来的社会和健康风险,本研究旨在评估接触酒精媒体内容对开始吸食大麻年龄的交叉影响。研究方法:830 名中学生(53% 为女性)纵向报告了电影酒精接触和开始吸食大麻的情况,直至高中毕业。离散时间生存模型检验了电影酒精暴露是否能预测基线时未吸食大麻的学生随后开始吸食大麻的情况,并控制了人口、社会和行为协变量。此外,还探讨了性别与电影酒精暴露之间的交互作用。研究结果三分之一(33%)的参与者在报告开始吸食大麻时,估计平均电影酒精接触时间为 5.57 小时(SD = 4.29)。在根据人口统计学变量调整的模型中,电影接触时间每增加 1 小时,预测开始吸食大麻的概率会显著增加 16%,而在根据人口统计学、行为和社会变量调整的模型中,预测开始吸食大麻的概率会显著增加 14%。没有观察到性别差异。结论青少年更多接触媒体中的酒精内容与更早开始吸食大麻有关,这超出了其他与病因相关的人口、行为和社会变量。跨物质媒体接触的影响值得进一步探讨,在制定针对青少年药物使用的预防性干预措施时应加以考虑。

Cross-substance Effects of Adolescent Exposure to Alcohol Content in Popular Movies on Cannabis Initiation
Objective: 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. Method: 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. Results: 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. Conclusions: 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.
