Despite the potential negative health effects of electronic cigarettes (e-cigarettes), these devices are increasing in popularity worldwide, especially among youth.
We compared data from two cross-sectional studies conducted in Poland among students aged 15-19 years in 2010-2011 and 2013-2014. We tested differences between samples in the prevalence of e-cigarette use, tobacco cigarette smoking, and simultaneous use of both tobacco and e-cigarettes ("dual use") using a multilevel linear mixed model regression.
We found that the current use of e-cigarettes among adolescents in Poland was significantly higher in the 2013-2014 sample than the 2010-2011 sample (29.9% vs. 5.5%, respectively; p < .05). Dual use of tobacco and e-cigarettes was also significantly higher (21.8% vs. 3.6%, respectively; p < .05). Interestingly, the prevalence of smoking tobacco cigarettes also increased (from 23.9% in 2010-2011 to 38.0% in 2013-2014; p < .05).
Observed parallel increase in e-cigarette use and smoking prevalence does not support the idea that e-cigarettes are displacing tobacco cigarettes in this population.
尽管电子烟（e-cigarettes）可能对健康有负面影响，但这些设备在全球范围内越来越受欢迎，尤其是在年轻人中。
我们比较了 2010-2011 年和 2013-2014 年在波兰对 15-19 岁学生进行的两项横断面研究的数据。我们使用多级线性混合模型回归测试了样本中电子烟使用、吸烟和同时使用烟草和电子烟（“双重使用”）的流行率差异。
我们发现，波兰青少年在 2013-2014 年样本中当前使用电子烟的比例明显高于 2010-2011 年样本（分别为 29.9%和 5.5%；p<0.05）。同时使用烟草和电子烟的比例也明显更高（分别为 21.8%和 3.6%；p<0.05）。有趣的是，吸烟的比例也有所增加（从 2010-2011 年的 23.9%增加到 2013-2014 年的 38.0%；p<0.05）。
观察到电子烟使用和吸烟流行率的平行增加，并不支持电子烟在该人群中取代烟草的想法。
