The aims of this study were to determine if inter-school variation in smoking prevalence was due to differences in pupil composition or other school-level factors. A cohort of 13-14-year-olds (n = 7147) from 52 schools was followed-up 1 year later. Random effects logistic regression was used to examine school variation in smoking uptake and cessation, with and without adjustment for pupil composition. Inter-school variation in smoking prevalence is not caused by differences in pupil composition but is due to differences in the onset of smoking arising because of unmeasured school contextual or collective factors operating on pupils' decisions.
本研究的目的是确定学校间吸烟流行率的差异是由于学生构成的差异还是其他学校层面的因素。对来自52所学校的7147名13 - 14岁学生组成的队列进行了为期1年的随访。采用随机效应逻辑回归分析，在调整和未调整学生构成的情况下，检验学校间吸烟开始和戒烟情况的差异。学校间吸烟流行率的差异并非由学生构成的差异所致，而是由于未测量的学校环境或集体因素对学生决策产生影响，从而导致吸烟开始情况存在差异。
