目的是调查中学生经常光顾商店和注意烟草销售点(POS)展示与吸烟易感性或吸烟上瘾的关系。对2011年和2012年进行的一项以学校为基础的队列研究设计两项调查。背景：英国诺丁汉郡。研究对象为来自诺丁汉郡8所学校的2270名11-16岁儿童。测量我们调查了吸烟易感性和吸烟状态的变化与光顾商店的频率和注意到POS展示和识别的烟草品牌数量的关系，控制了一系列潜在的混杂因素。对吸烟的易感性是通过一组三个问题来定义的，包括尝试吸烟的意图、明年内吸烟的可能性以及如果最好的朋友提供香烟的话吸烟的可能性。为了进行分析，我们使用了多项Logistic回归。在从不吸烟的非易感人群中，注意到POS表现更频繁与吸烟易感风险的增加独立相关[调整后的相对风险比(RRR)=1.74；99%可信区间(CI)=1.13-2.69]，但与吸烟无关。在不容易吸烟的人中发现更多的品牌，会使易吸烟和成为吸烟者的风险增加一倍，但这对从不吸烟的人向吸烟的过渡没有显著影响。在基线水平的从不吸烟的易感人群中，注意到烟草POS显示的频率与吸烟没有明显的相关性。结论：注意到更频繁的烟草销售点展示并认识到更多的烟草品牌与英国青少年吸烟风险的增加相关，认识到更多的品牌与吸烟风险的增加正相关。
Aims To investigate the association between frequency of visiting shops and noticing of tobacco point-of-sale (PoS) displays and the development of susceptibility to smoking, or smoking uptake, in secondary school students. Design Two surveys of a school based cohort study carried out in 2011 and 2012. Settings Nottinghamshire, UK. Participants A total of 2270 children aged 11-16 years from eight schools in Nottinghamshire. Measurements We investigated changes in susceptibility to smoking and smoking status in relation to frequency of visiting shops and noticing PoS displays and number of tobacco brands recognized, controlling for a range of potential confounders. Susceptibility to smoking was defined using a set of three questions covering intentions to try smoking, to smoke within the next year and likelihood of smoking if a best friend offered a cigarette. For the analysis we used multinomial logistic regression. Findings Among non-susceptible never smokers, noticing PoS displays more frequently was associated independently with an increased risk of becoming susceptible to smoking [adjusted relative risk ratio (RRR)= 1.74; 99% confidence interval (CI)= 1.13-2.69], but was not associated with smoking uptake. Recognizing a higher number of brands among non-susceptible never smokers doubled the risk of becoming susceptible to smoking and of becoming a smoker, but this did not have a significant effect on transition to smoking among susceptible never smokers. Frequency of noticing tobacco PoS displays was not associated significantly with smoking uptake among those who were susceptible never smokers at baseline. Conclusions Noticing tobacco point-of-sale displays more often and recognizing a higher number of tobacco brands is associated with an increased risk of becoming susceptible to smoking among adolescents in the United Kingdom, and recognizing a higher number of brands is associated positively with an increased risk of smoking uptake.
