Abstract [en]

Electronic (e) cigarettes are portrayed as a substitute for conventional cigarettes and as a means for smoking cessation. In contradiction, much of the marketing is designed to appeal to teenagers and nonsmokers. Aim: to estimate the prevalence of e-cigarette use in relation to smoking habits and demographic factors in teenagers. Within the Obstructive Lung Disease in Northern Sweden (OLIN) studies a cohort study of schoolchildren (n=2430) was initiated at age 7-8y, with follow-ups at age 11-12y, 14-15y and 19y by completion of an extended ISAAC questionnaire. Questions on smoking and snus use were included from age 14-15y and use of e-cigarettes at 19y. At age 19y, 22.0% (95%CI 20.3-23.7) had ever tried e-cigarettes, with higher proportion in boys than girls, 28.3 vs 15.2% p<.001. The prevalence of current use was 4.4% (95%CI 3.6-5.2), also higher among boys, 5.4 vs 3.4% p=.01. Current smoking (10.3%) was slightly higher in girls than boys, 11.1 vs 9.0% p=.20. Of current e-cigarette users, 39% were smokers, 22% ex-smokers and 39% nonsmokers. ‘Ever tried’ e-cigarettes was related to tobacco use at age 14-15y: 60.9% in smokers and 50.8% in snus users, however 19.6% of nonsmokers had tried e-cigarettes. In adjusted logistic regression analysis, current e-cigarette use was related to male sex (OR 2.1 95%CI 1.7-2.7), former smoking (OR 3.6 95%CI 2.5-5.3), current smoking (OR 5.3 95%CI 3.9-7.4), use of snus (OR 1.6 95%CI 1.3-2.1) and inversely related to eating healthy diet (OR 0.9 95%CI 0.8-0.9). There were no significant associations with parental smoking, socioeconomic status, physical activity or having asthma. In summary, e-cigarette use was common among smokers but alarmingly almost 40% of e-cigarette users at age 19y were nonsmokers.
