E-cigarette use among young adults in Poland: Prevalence and characteristics of e-cigarette users.

Purpose: Electronic cigarette (e-cigarette) use is one of the most popular alternatives to conventional cigarette smoking. This study aimed to investigate the prevalence of cigarette and e-cigarette use among university students from Poland, with particular emphasis on ever and current cigarette and e-cigarette use as well as smoking initiation age.

Patients And Methods: A cross-sectional survey was conducted between 2017 and 2018 in a group of university students in 5 academic centers in Poland. The questionnaire addressed 46 questions about personal attitudes toward cigarette smoking and e-cigarette use.

Results: Data were collected from 7324 participants (67.3% females, aged 21.9 ± 2.1 years), with an overall response rate of 70.1%. Among participants, 71.2% had ever smoked a cigarette, and almost half of the respondents (45%) declared ever use of an e-cigarette. The mean age of first use of a cigarette was significantly lower (16.5 ± 2.5 y-old) than of an e-cigarette (18.6 ± 2.2 y-old; p < 0.001). Exclusive cigarette smoking was declared by 12.9%, 1.3% were e-cigarette users and 1.5% were dual users. Those in the medical field were less likely to try e-cigarettes (odds ratio, OR = 0.73) or to currently smoke conventional cigarettes (OR = 0.82). Older participants were more likely to have ever smoked conventional cigarettes (OR = 1.06), but less likely to have ever used e-cigarettes (OR = 0.88).

Conclusions: In this study, we found a high proportion of young adults who have tried e-cigarettes with both regional and demographic differences. The education profile influences cigarette smoking and e-cigarette use behaviors.
