这项研究评估了青少年的烟草使用轨迹，预测了成年早期的尼古丁依赖以及这些轨迹何时开始出现分歧。作为一项大型预防试验后续行动的一部分，本研究评估了 1,017 名从青春期早期（12 岁）到成年早期（28 岁）的个体。参与者是从密苏里州堪萨斯城的八所中学招募的。学生基线时正在进入六年级或七年级。吸烟情况在基线、6个月、高中期间每年随访一次以及此后每18个月一次直到28岁进行评估。研究目标是确定(a)是否可以在青春期早期和成年初期（12-24岁）之间确定不同的每周吸烟轨迹； (b) 在发展过程中这些轨迹何时出现分歧； (c) 哪些轨迹可以预测成年早期（26-28 岁）的尼古丁依赖。四轨迹混合模型（弃权者、低度用户、后期稳定用户和早期稳定用户）证明了与数据的最佳拟合。与低使用率轨迹中的成员相比，日益高使用率轨迹中的成员使参与者变得尼古丁依赖的相对风险更大。一般线性模型显示，早在第一波数据收集（12 岁）时，早期稳定使用者的每周香烟消费量就较高，并且到 15 岁时，所有其他轨迹之间存在显着差异。研究结果支持在初中或初中早期实施吸烟预防计划，并表明到 12 岁时每周至少吸两支烟的青少年可能会受益。来自额外的成瘾预防工作。
This study evaluated the adolescent tobacco-use trajectories that predict nicotine dependence in early adulthood and when these trajectories start to diverge. As part of a follow-up to a large prevention trial, the present study evaluated 1,017 individuals from early adolescence (age 12) to early adulthood (age 28). Participants were recruited from eight middle schools in Kansas City, Missouri. Students were entering 6th grade or 7th grade at baseline. Smoking was evaluated at baseline, 6 months, at annual follow-ups through high school, and every 18 months thereafter until age 28. The study goals were to determine (a) whether distinct weekly tobacco-use trajectories could be identified between early adolescence and emerging adulthood (ages 12-24); (b) when during development these trajectories diverged; and (c) which trajectories could predict nicotine dependence in early adulthood (ages 26-28). A four-trajectory mixed model (abstainers, low users, late stable users, and early stable users) demonstrated the best fit to the data. Membership in increasingly high-use trajectories placed participants at greater relative risk for becoming nicotine dependent than did membership in lower-use trajectories. General linear models showed greater weekly cigarette consumption for early stable users as early as the first wave of data collection (age 12) and significant differences among all other trajectories by age 15. The findings support the implementation of smoking prevention programs early in middle or junior high school and suggest that adolescents who are already smoking at least two cigarettes per week by age 12 may benefit. from additional addiction prevention efforts.
