目的对青春期吸烟轨迹的异质性及其相关的危险因素知之甚少。本研究的目的是(1)实证识别吸烟轨迹，(2)识别轨迹组成员的危险因素。设计潜在增长混合模型识别人群吸烟轨迹。研究对象来自马里兰州某学区的7所中学，参与者包括1320名6年级至9年级的学生，在6年级秋季进行了吸烟危险因素测量，并在6年级至9年级的5个不同场合对吸烟阶段进行了评估，发现5种不同的吸烟轨迹。总体而言，作为女性。有吸烟的朋友。与从不吸烟的人相比，越轨接受和结果预期与成为意向者、延迟的自动扶梯、早期试验者和早期使用者的可能性增加相关。此外，与从不吸烟的人进行比较，发现了意向者、早期实验者和早期使用者的独特识别符，但没有延迟的自动扶梯。结论中学生从不打算吸烟到成为吸烟者的方式存在很大的异质性。对预防计划的影响进行了讨论。
Aims Little is known about the heterogeneity in and risk factors associated With trajectories of smoking during adolescence. This study aimed to (1) identify smoking trajectories empirically and (2) identify risk factors for trajectory group membership.Design Latent growth mixture models were used to identify population smoking trajectories. and logistic regression was used to estimate risk factors for group membership.Setting The participants were drawn from seven middle schools in a Maryland school district.Participants Participants consisted of 1320 6th graders who Were followed to the 9th grade.Measurements Measurements of smoking risk factors were made in the fall of 6th grade and smoking stage was assessed on five different occasions between the fall of 6th and 9th grades.Findings Five distinct smoking trajectories were identified. Overall, being female. having friends who smoked. deviance acceptance and outcome expectations were associated with an increased likelihood of being an intender, delayed escalator, early experimenter and early user compared to a never smoker. Additionally, comparisons with never smokers revealed unique identifiers for intenders, early experimenters and early users, but not delayed escalators.Conclusions There is much heterogeneity in the manner in which middle-schoolers progress from having no intention of smoking to becoming smokers. Implications for prevention programs are discussed.
