This study utilizes a large sample of 8th, 10th, and 12th-grade youth in Arizona (n = 34,373). Five cycles of this biannual survey were used to examine the longitudinal trends. Multivariate logistic regressions were used to identify the key risk factors for past 30-day and lifetime cigarette use. Across all survey cycles, peers played a consistently significant role in smoking behaviors. Those youth with drug-free friends and friends who disapproved of substance use were less likely to engage in smoking behaviors. Further, various community, school, and familial factors were predictive of smoking behavior, though less consistently than peer-level determinants. This study demonstrates that peers consistently play a critical role in cigarette smoking behavior. As such, interventions and future research need to examine further how prosocial peers can be leveraged to reduce smoking behaviors and the associated health outcomes.

这项研究利用了亚利桑那州 8 年级、10 年级和 12 年级青少年的大量样本（n = 34,373）。这项半年调查的五个周期用于检查纵向趋势。使用多变量逻辑回归来确定过去 30 天和终生吸烟的关键风险因素。在所有调查周期中，同龄人在吸烟行为中始终发挥着重要作用。那些有不吸毒朋友和不赞成使用药物的朋友的青少年不太可能有吸烟行为。此外，各种社区、学校和家庭因素都可以预测吸烟行为，尽管与同龄人水平的决定因素相比不太一致。这项研究表明，同龄人在吸烟行为中始终发挥着关键作用。因此，干预措施和未来的研究需要进一步研究如何利用亲社会同伴来减少吸烟行为和相关的健康结果。
