Background: Tobacco use is the leading preventable cause of death worldwide. Besides cigarette smoking, waterpipe and e-cigarettes are gaining popularity among young adults. Medical students' smoking behavior is of particular interest because of their impending role in health promotion as future physicians. Aim of our study is to examine the prevalence and predictors of cigarette, waterpipe and e-cigarette use and the association of tobacco use with self-reported health status in an international sample of medical students., Methods: In a multicenter cross-sectional study data on different aspects of health behavior were collected from medical students of 65 nationalities using a self-administered questionnaire in Germany (Dresden, Munich) and Hungary (Budapest, Pécs). The survey was conducted among 1st, 3rd and 5th year students. To explore associations between smoking behavior and socio-cultural factors Pearson's chi 2 -tests and multivariate binary logistic regression analyses were performed., Results: The largest subpopulations were formed by German (n = 1289), Hungarian (n = 1055) and Norwegian (n = 147) students. Mean age was 22.5 ± 3.3 years. Females represented 61.6% of the sample. In the whole sample prevalence of cigarette smoking was 18.0% (95% CI 16.6-19.4%), prevalence of waterpipe use was 4.8% (95% CI 4.0-5.7%), that of e-cigarette 0.9% (95% CI 0.5-1.2%). More males (22.0%) than females (15.5%) reported cigarette smoking. The lowest prevalence of cigarette smoking was found among Norwegian students (6.2%). Cigarette smokers were older, waterpipe users were younger than non-users. E-cigarette use was not associated with age of the students. Religious involvement was protective only against cigarette smoking. Financial situation showed no association with any kind of tobacco consumption. Cigarette smokers and e-cigarette users were less likely to report very good or excellent health status., Conclusions: Cigarette smoking is still the most popular way of consuming tobacco, although alternative tobacco use is also prevalent among medical students. To further health consciousness, medical schools should pay more attention to students' health behavior, especially their smoking habits. Tobacco prevention and cessation programs for medical students should consider not only the health risks of cigarette smoking but the need to discourage other forms of tobacco use, such as waterpipe.

Medical students as future physicians will have an important role in tobacco control; therefore, their tobacco use behavior is of particular interest. Consumption of combustible tobacco (cigarettes, waterpipes, cigars, and pipes) is prevalent throughout Europe, whereas smokeless tobacco use is common mainly in the Nordic countries. Objectives: Aim of our study is to assess tobacco use among medical students from different countries studying in Hungary with special focus on students from Norway where smokeless tobacco is widely used. A self-administered questionnaire survey was carried out to measure current tobacco use. Results: The survey included 1337 students from Hungary, Norway, Germany, and from other countries (Multinational group). The lowest prevalence of cigarette smoking was found among students from Norway (13.0%) when compared with students from Hungary (21.5%), Germany (34.2%), or with students in the Multinational group (29.5%). Conversely, prevalence of smokeless tobacco use was the highest among students from Norway (40.9%) when compared with students from Hungary (1.4%), Germany (2.6%), or with students in the Multinational group (6.2%). Waterpipes, cigars, and pipes were rarely used, mostly only 1–3 times a month in all groups. More than half of Norwegian students used some form of tobacco (smokeless and/or combustible tobacco). Conclusions: Considering the impending role of medical students in tobacco control, faculties of medicine should sensitize their students on the topic of possible health risks associated with combustible and smokeless tobacco products. Culturally tailored tobacco cessation programs need to be offered to medical students coming from different cultural backgrounds. [ABSTRACT FROM AUTHOR]

Use of electronic cigarettes (e-cigarettes) is gaining popularity among young adults. Medical students' nicotine use behavior is of particular interest because of their impending role in health promotion. Objectives: Aim of our study is to assess changes that occurred between 2016 and 2018 in the prevalence of e-cigarette use among medical students and to explore associations between e-cigarette use, demographic characteristics, and cigarette smoking. Self-administered questionnaire surveys were used to obtain cross-sectional data of medical students in Budapest and Pécs, Hungary, and Dresden, Germany. Results: Sample sizes for 2016 and 2018 were 2297 and 1514, respectively. In the whole sample, past-30-day use of e-cigarettes increased from 4.5% to 8.0% (p < 0.001). The increase in e-cigarette use was significant in both genders (from 3.6% to 5.6% among females, p = 0.028, and from 5.9 to 11.4% among males, p < 0.001). Prevalence of e-cigarette use was higher among Hungarian students than among German students (2.2% versus 5.7% in 2016, and 4.1% versus 10.5% in 2018, p < 0.05 for both years). There was no significant difference in e-cigarette use among different academic years. The ratio of e-cigarette users increased significantly among current cigarette smokers but not among nonsmokers. We could not detect a decrease in cigarette smoking. Conclusions: Prevalence of e-cigarette use increased significantly among medical students without a reduction in cigarette smoking. Medical schools should add the topic of e-cigarettes to their curricula and need to develop cessation programs to help their students quit both cigarettes and e-cigarettes. [ABSTRACT FROM AUTHOR]
