目的：青少年使用混合能量饮料（AmED）的行为最近受到越来越多的关注。先前的研究已经确定 AmED 与醉酒之间存在密切联系，并表明了解与 AmED 使用之间的关联的重要性。在这项研究中，我们将咖啡因作为每日咖啡、茶、可乐饮料和能量饮料的摄入量，并研究了每日咖啡因摄入量是否与 AmED 使用和醉酒有关。方法：我们使用多级结构方程模型 (SEM) 和 2013 年冰岛青年横断面调查数据，对冰岛所有 31 所大专院校 16-17 岁的学生进行调查（N=5,784；回答率 75%；女生 51%）。结果：我们的主要模型非常适合数据，比较拟合指数为 0.994，均方根误差近似为 0.042。在四个每日咖啡因摄入量变量中，对于女孩和男孩来说，咖啡与 AmED 的关系最强，其次是能量饮料摄入量。对于男女而言，每日咖啡因消费变量与醉酒之间的直接关系通常较弱，但所有每日咖啡因消费变量与醉酒之间的总体关系大部分归因于 AmED 的中介作用。在我们的主要模型中，AmED 消耗量也与醉酒密切相关（标准化 beta s = .74.79）。结论：无论咖啡因的摄入方式如何，16-17 岁青少年的咖啡因摄入量与 AmED 摄入量的增加密切相关。无论是在个人层面还是在学校层面，AmED 都与醉酒呈强烈且正相关的关系。
Objective: Adolescent use of alcohol mixed with energy drinks (AmED) has recently received increased attention. Previous studies have established a strong link between AmED and drunkenness and suggest the importance of understanding associations with AmED use. In this study, we operationalized caffeine as daily consumption of coffee, tea, cola drinks, and energy drinks, and examined whether daily caffeine consumption relates to AmED use and drunkenness. Method: We used multilevel structural equation modeling (SEM) with data from the 2013 Youth in Iceland cross-sectional survey among students, ages 16-17 years, who attended all of Iceland's 31 junior colleges (N=5,784; 75% response rate; 51% girls). Results: Our primary model fit the data very well with a comparative fit index of .994 and root mean square error of approximation of .042. Of the four daily caffeine consumption variables, coffee had the strongest relationship with AmED for both girls and boys, followed by energy drink consumption. The direct relationship between the daily caffeine consumption variables and drunkenness was generally weak for both genders, but the majority of the total relationship between all daily caffeine consumption variables and drunkenness was attributable to mediation through AmED. In our primary model, AmED consumption was also very strongly related to drunkenness (standardized beta s = .74.79). Conclusions: Caffeine use among adolescents ages 16-17 years is strongly related to increased consumption of AmED, irrespective of mode of caffeine consumption. AmED is strongly and positively associated with drunkenness on both individual and school levels.
