青少年吸烟者往往有同龄人吸烟，但尚不清楚这是否是吸烟同龄人的自我选择造成的，或者这是否是吸烟（偶发吸烟）的因果效应。作者使用学校导师组当前吸烟率（英国高中同伴吸烟的无偏见衡量标准）来估计同伴吸烟对高中生吸烟事件的独立影响。在一项针对英国诺丁汉郡 10 所高中 13-15 岁（9 年级和 10 年级）儿童的前瞻性队列研究中，2000 年对 2,881 名学生的吸烟行为进行了调查，2001 年又对 2,109 名学生（73%）重复了这项调查。在 1,766 名非吸烟者中，有 267 名吸烟者（15%）。 2000 年。 2000 年，女孩、父母或兄弟姐妹吸烟的学生以及学校辅导员群体当前吸烟流行率的调整后吸烟事件发生率显着较高（流行率最高相对于最低四分位的相对几率 = 1.78，95% 置信区间：1.20、2.64）。在 2001 年的研究中，这种导师群体效应与是否有一个最好的朋友吸烟无关。因此，接触其他吸烟学生的学生吸烟率会增加，而在学校预防吸烟可能会减少青少年吸烟。
Adolescent smokers tend to have peers who smoke, but it is unclear whether this arises from self-selection of smoking peers or whether this is a causal effect on the uptake of smoking (incident smoking). The authors used school tutor group current smoking prevalence, an unbiased measure of peer smoking in high schools in the United Kingdom, to estimate the independent effect of peer smoking on incident smoking among high school students. In a prospective cohort study of children aged 13-15 years (grades 9 and 10) in 10 high schools in Nottinghamshire, United Kingdom, smoking behavior was surveyed in 2,881 students in 2000, and the survey was repeated in 2,109 students (73%) in 2001. There were 267 incident smokers (15%) among the 1,766 nonsmokers in 2000. The adjusted odds of incident smoking were significantly higher in girls, in students with parents or siblings who smoke, and in relation to school tutor group current smoking prevalence in 2000 (relative odds for highest relative to the lowest quartile of prevalence = 1.78, 95% confidence interval: 1.20, 2.64). This tutor group effect was independent of having a best friend who smoked in the 2001 study. Incident smoking is therefore increased among students exposed to other students who smoke, and preventing smoking at school may reduce adolescent smoking.
