The main objective of this study was to identify the risk factors and develop a decision tree model of heavy episodic drinking (HED) among adolescents. Data were obtained from a representative nationwide Korean population. Nine variables (such as last 30 days smoking, school grade, sex, depression, school achievement, level of stress, region, and economic status) were found as risk factors of HED. On the highest level of the tree root, major classification rule was played by dividing based on the last 30 days smoking and school grades. These findings should be helpful for school and mental healthcare providers to detect Korean adolescents with high possibility of HED, which will aid in planning of healthcare interventions for at-risk adolescents.
本研究的主要目的是确定青少年重度饮酒（HED）的危险因素，并建立决策树模型。数据来自具有代表性的韩国全国性人群。九个变量（如过去 30 天吸烟、年级、性别、抑郁、学业成绩、压力水平、地区和经济状况）被确定为 HED 的危险因素。在树根部的最高级别，主要分类规则是根据过去 30 天吸烟和年级进行划分。这些发现有助于学校和精神保健提供者发现有高度 HED 可能性的韩国青少年，从而为高危青少年的医疗干预计划提供帮助。
