一些人认为电子烟具有减少危害的潜力，可以有效地用作戒烟设备。然而，国际上有新的证据表明，年轻人越来越多地使用烟草，人们担心这可能会增加烟草的摄入量。英国很少有研究调查不吸烟儿童使用电子烟的流行情况或与吸烟意图的关系。对威尔士 6 年级（10-11 岁）儿童的横断面调查。大约 1500 名儿童完成了有关电子烟使用、父母和同伴吸烟以及吸烟意图的问题。对从不吸烟的儿童进行逻辑回归分析，并根据学校水平的聚类进行调整，检查吸烟规范与电子烟使用的关联，以及电子烟使用与未来 2 年内吸烟意图的关联。大约 6% 的六年级儿童（包括 5% 的从不吸烟者）报告曾使用过电子烟。与父母既不吸烟也不使用电子烟的孩子相比，如果父母同时使用烟草和电子烟，孩子最有可能使用电子烟（OR=3.40；95% CI 1.73至6.69）。使用电子烟与吸烟意愿相关（OR=3.21；95% CI 1.66 至 6.23）。虽然很少有孩子报告说他们会在 2 年内吸烟，但使用过电子烟的儿童不太可能报告他们在 2 年内绝对不会吸烟，而更有可能说他们可能会吸烟。电子烟代表了儿童尼古丁实验的一种新形式。研究结果与以下假设一致：儿童使用电子烟是为了模仿父母和同伴的吸烟行为，并且电子烟的使用与较弱的反吸烟意图有关。
E-cigarettes are seen by some as offering harm reduction potential, where used effectively as smoking cessation devices. However, there is emerging international evidence of growing use among young people, amid concerns that this may increase tobacco uptake. Few UK studies examine the prevalence of e-cigarette use in non-smoking children or associations with intentions to smoke. A cross-sectional survey of year 6 (10–11-year-old) children in Wales. Approximately 1500 children completed questions on e-cigarette use, parental and peer smoking, and intentions to smoke. Logistic regression analyses among never smoking children, adjusted for school-level clustering, examined associations of smoking norms with e-cigarette use, and of e-cigarette use with intentions to smoke tobacco within the next 2 years. Approximately 6% of year 6 children, including 5% of never smokers, reported having used an e-cigarette. By comparison to children whose parents neither smoked nor used e-cigarettes, children were most likely to have used an e-cigarette if parents used both tobacco and e-cigarettes (OR=3.40; 95% CI 1.73 to 6.69). Having used an e-cigarette was associated with intentions to smoke (OR=3.21; 95% CI 1.66 to 6.23). While few children reported that they would smoke in 2 years’ time, children who had used an e-cigarette were less likely to report that they definitely would not smoke tobacco in 2 years’ time and were more likely to say that they might. E-cigarettes represent a new form of childhood experimentation with nicotine. Findings are consistent with a hypothesis that children use e-cigarettes to imitate parental and peer smoking behaviours, and that e-cigarette use is associated with weaker antismoking intentions.
