We studied the association between individual and contextual variables and the use of tobacco, alcohol, or cannabis in the last 30 days preceding the study, considering the hierarchical nature of students nested in schools. We used the 7th Chilean National School Survey of Substance Use (2007) covering 45,273 students (aged 12-21 years old) along with information from 1465 schools provided by the Chilean Ministry of Education. Multilevel univariable and multivariable logistic regression models were performed. We found a significant intra-class correlation within schools for all substances in the study. Common (e.g., availability of pocket money, more time spent with friends, poor parental monitoring, poor school bonding, bullying others, and lower risk perception of substance use) and unique predictors (e.g., school achievement on national tests) were identified. These findings may help in planning and conducting preventive interventions to reduce substance use.
我们研究了个体变量和环境变量与研究前30天内烟草、酒精或大麻使用之间的关联，同时考虑了嵌套于学校中的学生的层级性质。我们使用了智利第七次全国学校物质使用调查（2007年），该调查涵盖了45273名学生（年龄在12至21岁之间），并结合了智利教育部提供的1465所学校的信息。我们进行了多水平单变量和多变量逻辑回归模型分析。我们发现，对于研究中的所有物质，学校内部存在显著的组内相关性。我们确定了一些共同的预测因素（例如，零花钱的可获得性、与朋友相处的时间更多、父母监管不力、学校归属感差、欺负他人以及对物质使用的风险认知较低）和独特的预测因素（例如，全国考试中的学业成绩）。这些发现可能有助于规划和开展预防性干预措施，以减少物质使用。
