This study examined the role of depressive symptoms on trajectories of electronic nicotine delivery systems (ENDS), cigarette, and cannabis use across 4.5 years in a sample of college students aged 18-19 at the initial study wave.
Participants were 2,264 students enrolled in one of 24 Texas colleges that participated in a multi-wave study between 2014 and 2019. Latent growth mixture models were fit to identify longitudinal trajectories for past 30-day ENDS, cigarette, and cannabis use over a 4.5-year period. Class membership was regressed on baseline depressive symptoms in multinomial regression models.
Four trajectory classes were identified for each product: abstainer/minimal, decreasing, increasing, and high. Depressive symptoms were associated with a greater likelihood of belonging to the decreasing, increasing, and high trajectory classes relative to the abstainer/minimal class for all products, with the exception of the increasing ENDS class and the decreasing cannabis class.
The findings demonstrate that there is considerable similarity across trajectories of ENDS, cigarette, and cannabis use during traditional collegiate years. Furthermore, depressive symptoms increased the likelihood of belonging to substance using trajectory classes for all products.
本研究考察了抑郁症状在 4.5 年时间内对 18-19 岁大学生样本中电子尼古丁传送系统（ENDS）、香烟和大麻使用轨迹的影响。
参与者为 2014 年至 2019 年间参加了一项多波研究的 24 所德克萨斯大学中的 2264 名学生。使用潜在增长混合模型来确定过去 30 天内 ENDS、香烟和大麻使用的 4.5 年期间的纵向轨迹。在多项回归模型中，将基线抑郁症状回归到类别成员身份。
为每个产品确定了四个轨迹类别：禁欲/最低、减少、增加和高。与禁欲/最低类相比，抑郁症状与属于减少、增加和高轨迹类别的可能性更大，所有产品均如此，除了增加的 ENDS 类和减少的大麻类。
研究结果表明，在传统大学生涯中，ENDS、香烟和大麻使用的轨迹具有相当大的相似性。此外，抑郁症状增加了所有产品的物质使用轨迹类别的可能性。
