摘要:Background. Health professionals play an essential role in tobacco control. Our objective was to assess Iranian dental students' attitudes towards tobacco control. Methods. Eight dental schools were randomly selected, and a survey using Global Health Professions Student Survey (GHPSS) instrument was conducted among dental students in 2010 in Iran. The chi-square test served for statistical analyses. Results. Of the participants (325 students, 66% female), about one-fifth (21%) were current tobacco (including cigarettes and waterpipe) users. A clear majority (over 80%) of the students agreed as to the responsibility of health professionals on serving as role models for patients and the public, routinely advising patients using tobacco to quit, and giving patients advice about smoking cessation. Over 75% believed that cigarette-smoking health professionals are less likely to advise their patients to stop smoking. Current tobacco users were significantly less likely to agree with these beliefs (). Conclusion. Future oral health professionals have generally positive attitudes towards tobacco control. However, their own current tobacco use has a significant negative impact on these attitudes, an impact which ought to be taken into account in tobacco control.
