We examined the role of depressive symptoms in the longitudinal trajectory of the number of tobacco products used across young adulthood, ages 18-30 years, and whether peer tobacco use exacerbated the effects of the depressive symptoms. Participants were 4534 initially 18-25-year-old young adults in the Marketing and Promotions Across Colleges in Texas project (Project M-PACT), which collected data across a 4.5-year period from 2014 to 2019. Growth curve modeling within an accelerated design was used to test study hypotheses. Elevated depressive symptoms were associated with a greater number of tobacco products used concurrently and at least six months later. The number of tobacco-using peers moderated the association between depressive symptoms and the number of tobacco products trajectory. Young adults with elevated depressive symptoms used a greater number of tobacco products but only when they had a greater number of tobacco-using peers. Findings indicate that not all young adults with depressive symptoms use tobacco. Having a greater number of tobacco-using peers may facilitate a context that both models and encourages tobacco use. Therefore, tobacco prevention programs should aim to include peer components, especially for young adults.
我们研究了抑郁症状在年轻人（18-30 岁）中吸烟数量的纵向轨迹中的作用，以及同伴吸烟是否会加剧抑郁症状的影响。参与者是德克萨斯州大学市场营销和推广项目（Project M-PACT）中的 4534 名最初年龄在 18-25 岁的年轻人，该项目从 2014 年到 2019 年进行了为期 4.5 年的数据收集。在加速设计中使用增长曲线模型来检验研究假设。较高的抑郁症状与同时使用和至少六个月后使用的烟草产品数量较多有关。使用烟草的同伴数量调节了抑郁症状与烟草产品轨迹数量之间的关系。抑郁症状较高的年轻人使用了更多的烟草制品，但只有当他们有更多的吸烟同伴时才会这样。研究结果表明，并非所有患有抑郁症状的年轻人都使用烟草。有更多的吸烟同伴可能会创造一个既能模仿又能鼓励吸烟的环境。因此，烟草预防计划应旨在包括同伴成分，特别是针对年轻人。
