前言和目的利用离散时间生存分析，在全国具有代表性的样本中研究大麻开始使用和过渡到大麻使用障碍（CUD）的预测因素。设计与方法数据来自6935名澳大利亚成年人的全国代表性样本。首次使用大麻年龄和CUD发病的回顾性数据用于构建伪纵向数据集和生存模型，用于评估与首次使用年龄和首次使用到CUD发病时间相关的因素。结果年龄最大的队列（1942-1951年出生）使用大麻的比例低于年轻队列，首次使用大麻的年龄也较大。多变量离散时间生存模型显示，在很小的时候使用其他物质、烟草和酒精以及精神障碍与使用大麻的风险增加有关。有7.5%
Introduction and AimsTo investigate the predictors of both initiation of cannabis use and transition to cannabis use disorder (CUD) in a nationally representative sample using discrete-time survival analyses.Design and MethodsData from a nationally representative sample of 6935 Australian adults. Retrospective data on age of first cannabis use and onset of CUD were used to construct pseudo-longitudinal datasets and survival models used to evaluate factors associated with age of first use and time from first use to onset of CUD.ResultsThe oldest cohort (born 1942-1951) had lower cannabis use than younger cohorts, with first use also occurring at an older age. Multivariable discrete-time survival models showed other substance use, tobacco and alcohol use at very young ages, and mental disorders were associated with increased risk of cannabis use. There were 7.5% of those
