The purpose of this study was to clarify the subgroup differences in the association between participation in school-based extracurricular activities and exercise and levels of cigarette, alcohol, or marijuana use during one's lifetime and in the past year. This study also sought to determine the optimal classification of subgroups based on four variables (participation in school-based extracurricular activities, exercise, gender, and school year). Data consisted of a combined sample (aggregate sample) from the Japanese School Survey Project on Alcohol and Other Drugs (JSPAD) conducted in 2004, 2006, and 2009. The aggregate sample consisted of 75,726 1st-, 2nd-, and 3rd-year students (37,697 males and 38,029 females) at full-time high schools nationwide that were selected by stratified, single-stage cluster sampling during each survey. The aggregate sample combined randomly selected samples of the same size from each year the survey was conducted. Results indicated that 63.4% of the entire sample participated in school-based extracurricular activities, 64.8% of males did so, and 61.9% of females did so. Results also indicated that 66.4% of the entire sample exercised outside of PE class, 79.2% of males did so, and 53.8% of females did so. In addition, the prevalence of cigarette, alcohol, or marijuana use was predicted from the four variables by multiple logistic regression analysis. Results yielded optimal subgroups for the prevalence of each drug's use. Results revealed (1) that participation in school-based extracurricular activities and gender were more predictive, whereas exercise was least predictive, (2) that the association between exercise and substance use measures varies subtly for each subgroup, suggesting the existence of a great variety of opportunities for high school students to exercise, and (3) that school year had a substantial and positive effect on drinking among students who actively participated in school-based extracurricular activities.
本研究的目的是阐明参与校内课外活动和体育锻炼与一生中及过去一年中香烟、酒精或大麻使用水平之间关联的亚组差异。本研究还试图根据四个变量（参与校内课外活动、体育锻炼、性别和学年）确定亚组的最佳分类。数据来自2004年、2006年和2009年开展的日本酒精及其他药物学校调查项目（JSPAD）的合并样本（汇总样本）。汇总样本包括全国全日制高中一、二、三年级的75726名学生（37697名男生和38029名女生），这些学生是在每次调查期间通过分层单阶段整群抽样选取的。汇总样本将每次调查中随机选取的相同规模的样本合并在一起。结果表明，整个样本中有63.4%的学生参与校内课外活动，其中男生为64.8%，女生为61.9%。结果还表明，整个样本中有66.4%的学生在体育课之外进行体育锻炼，其中男生为79.2%，女生为53.8%。此外，通过多元逻辑回归分析从这四个变量预测了香烟、酒精或大麻使用的患病率。结果得出了每种药物使用患病率的最佳亚组。结果显示：（1）参与校内课外活动和性别更具预测性，而体育锻炼的预测性最小；（2）体育锻炼与物质使用指标之间的关联在每个亚组中略有不同，这表明高中生有各种各样的体育锻炼机会；（3）学年对积极参与校内课外活动的学生的饮酒行为有显著的正向影响。
