Exposure to e-cigarette adverts increases children's positive attitudes towards using them. Given the similarity in appearance between e-cigarettes and tobacco cigarettes, we examined whether exposure to e-cigarette adverts has a cross-product impact on perceptions and attitudes towards smoking tobacco cigarettes.
Children aged 11-16 (n=564) were interviewed in their homes and randomised to one of three groups: two groups saw different sets of 10 images of e-cigarette adverts and one group saw no adverts. Of the 20 e-cigarette adverts, 10 depicted the product as glamorous and 10 depicted it as healthy. The children then self-completed a questionnaire assessing perceived appeal, harms and benefits of smoking tobacco cigarettes.
The analyses were conducted on 411 children who reported never having smoked tobacco cigarettes or used e-cigarettes. Exposure to the adverts had no impact on the appeal or perceived benefits of smoking tobacco cigarettes. While the perceived harm of smoking more than 10 cigarettes per day was similar across groups, those exposed to either set of adverts perceived the harms of smoking one or two tobacco cigarettes occasionally to be lower than those in the control group.
This study provides the first evidence that exposure to e-cigarette adverts might influence children's perceptions of smoking tobacco cigarettes, reducing their perceived harm of occasional smoking. These results suggest the potential for e-cigarette adverts to undermine tobacco control efforts by reducing a potential barrier (ie, beliefs about harm) to occasional smoking.
接触电子烟广告会增强儿童对使用电子烟的积极态度。鉴于电子烟与传统香烟在外观上的相似性,我们研究了接触电子烟广告是否会对儿童对传统香烟的认知和态度产生交叉影响。
对11至16岁的儿童(n = 564)进行家访,并将他们随机分为三组:两组观看不同的10张电子烟广告图片,一组不看广告。在20张电子烟广告图片中,10张将产品描绘得很有魅力,10张将其描绘得健康。然后孩子们自行填写一份问卷,评估对吸传统香烟的感知吸引力、危害和益处。
对411名报告从未吸过传统香烟或使用过电子烟的儿童进行了分析。接触广告对吸传统香烟的吸引力或感知益处没有影响。虽然各组中每天吸超过10支香烟的感知危害相似,但接触任何一组广告的儿童认为偶尔吸一两支传统香烟的危害低于对照组。
本研究首次证明,接触电子烟广告可能会影响儿童对吸传统香烟的认知,降低他们对偶尔吸烟危害的感知。这些结果表明,电子烟广告有可能通过减少偶尔吸烟的潜在障碍(即对危害的认知)来破坏烟草控制工作。
