The aim was to investigate whether e-cigarette use predicts later experimentation with conventional cigarettes.
During the 2016/2017 school year, 2,388 children and adolescents from Baden-Württemberg, Mecklenburg-Western Pomerania, North Rhine-Westphalia, Rhineland-Palatinate, Schleswig-Holstein and Saxony who had never smoked conventional cigarettes before took part in a survey over a 2-year period (mean age 11.8 years, SD = 1.21; 49.6 % female).
At baseline, 85 pupils (3.6 %) reported that they had already tried e-cigarettes at least once. By the end of the observational period, 430 of the sample had tried conventional cigarettes (18.0 %). After statistical control for age, sex, migration background, type of school, socioeconomic status, sensation-seeking, alcohol use, and school performance, the adjusted relative risk of experimentation with conventional cigarettes was 85 % higher (adjusted relative risk = 1.85, 95 % CI [1.34 - 2.56]) for pupils who had used e-cigarettes at baseline. Further analyses revealed that the risk was higher among adolescents with low sensation-seeking scores.
Among young never-smokers, experimentation with conventional cigarettes is more common in those who used e-cigarettes before than among those who have not tried e-cigarettes before. This effect seems to be stronger among adolescents who, in general, have a lower risk of starting to smoke.
本研究旨在调查使用电子烟是否会增加日后尝试传统卷烟的可能性。
在2016/2017学年，来自巴登-符腾堡州、梅克伦堡-前波美拉尼亚州、北莱茵-威斯特法伦州、莱茵兰-普法尔茨州、石勒苏益格-荷尔斯泰因州和萨克森州的2388名从未吸过传统卷烟的儿童和青少年参与了一项为期两年的调查（平均年龄11.8岁，标准差=1.21；49.6%为女性）。
在基线时，85名学生（3.6%）报告称他们至少尝试过一次电子烟。到观察期结束时，样本中有430人尝试过传统卷烟（18.0%）。在对年龄、性别、移民背景、学校类型、社会经济地位、寻求刺激、饮酒情况和学业成绩进行统计控制后，基线时使用过电子烟的学生尝试传统卷烟的调整后相对风险高85%（调整后相对风险=1.85，95%置信区间[1.34 - 2.56]）。进一步分析显示，在寻求刺激得分较低的青少年中，这种风险更高。
在从未吸烟的年轻人中，之前使用过电子烟的人比未使用过电子烟的人更常尝试传统卷烟。这种影响在一般开始吸烟风险较低的青少年中似乎更强。
