Objective: This study seeks to describe current e-cigarette users' patterns of use including primary motivation for use, dual use, use with nicotine and principal flavour used, according to individuals' sociodemographic characteristics and conventional tobacco consumption in Barcelona, Spain.
Design, setting and participants: This is a cross-sectional study of adult (≥18) current e-cigarette users of Barcelona (n=600), recruited in 2015. Researchers calculated percentages and ORs with their 95% CIs of users' e-cigarette use with nicotine, primary motivation for use and preferred flavour. The analyses were stratified by sociodemographic variables including sex, age and level of education and by patterns of e-cigarette use and past and current conventional tobacco use.
Results: The most prevalent motivation for using e-cigarettes was to reduce tobacco smoking (48%, n=288), followed by quitting smoking (39.2%, n=235), and to use e-cigarettes in places where tobacco smoking was prohibited (10.2%, n=61). The most prevalent primary flavour used was tobacco (49%, n=294), followed by fruit (19.5%, n=117). People younger than 25 years old (OR=4.36, 95% CI 1.99 to 9.57) were more likely than older people to use them where smoking cigarettes was prohibited. A greater proportion of those in the youngest age group preferred fruit flavour compared with older individuals (29.3%, n=41).
Conclusions: Younger users of e-cigarettes and non-smokers are more likely to use flavours other than tobacco and to use e-cigarettes mainly for recreational purposes.
