Patterning of cigarette and e-cigarette use among young people remains poorly characterized. We aimed to describe these patterns in the UK Millennium Cohort Study at age 14 and 17 years.
Data on cigarette and e-cigarette use come from 9731 adolescents. Latent class analysis assigned participants to membership of classes of product use and multinomial logistic regression analyses assessed differences in the likelihood of belonging to classes by sociodemographic (age, gender, ethnicity, household income, maternal education and country of residence) and smoking-related social factors (caregiver tobacco use, caregiver e-cigarette use and peer smoking).
We identified four classes of use: 45.8% of adolescents 'continued to abstain' from cigarettes or e-cigarettes; 21.3% 'experimented' (used once or in the past but not currently) with cigarettes and/or e-cigarettes by age 17 but were not current users; 19.0% were 'late adopters', characterized by low levels of use at age 14 but high levels of experimentation and current use at age 17; and 13.9% were 'early adopters', characterized by high levels of experimentation and current use at ages 14 and 17. At age 17, 70.4% of 'early adopters' smoked cigarettes regularly plus an additional 27.3% experimented with cigarettes. Corresponding percentages for e-cigarettes were 37.9% and 58.9%. Tobacco and e-cigarette use by caregivers, and cigarette use by peers, were associated with being both 'late adopters' and 'early adopters'.
Approximately one in seven adolescents in the UK are 'early adopters' of nicotine products. This highlights the need to develop and implement effective policies to prevent nicotine use uptake.
青少年中香烟和电子烟的使用模式仍未得到充分描述。我们旨在通过英国千禧队列研究描述14岁和17岁青少年的这些模式。
关于香烟和电子烟使用的数据来自9731名青少年。潜在类别分析将参与者分配到产品使用类别中，多项逻辑回归分析评估了社会人口统计学因素（年龄、性别、种族、家庭收入、母亲教育程度和居住国家）以及与吸烟相关的社会因素（照顾者吸烟、照顾者使用电子烟和同伴吸烟）导致属于不同类别的可能性差异。
我们确定了四类使用情况：45.8%的青少年“继续戒除”香烟或电子烟；21.3%的青少年在17岁时“尝试过”（曾经使用过一次或过去使用过但目前不使用）香烟和/或电子烟，但不是当前使用者；19.0%是“晚期使用者”，其特点是14岁时使用水平较低，但17岁时尝试和当前使用水平较高；13.9%是“早期使用者”，其特点是14岁和17岁时尝试和当前使用水平较高。在17岁时，70.4%的“早期使用者”经常吸烟，另外27.3%尝试过吸烟。电子烟的相应比例分别为37.9%和58.9%。照顾者使用烟草和电子烟以及同伴吸烟与“晚期使用者”和“早期使用者”均相关。
英国约七分之一的青少年是尼古丁产品的“早期使用者”。这凸显了制定和实施有效政策以防止尼古丁使用的必要性。
