Factors associated with smoking habits among undergraduate medical students: a cross-sectional study

Abstract

Objectives: Determination of smoking habits of medical students in Belgrade and the factors influencing cigarette use. Methods: A cross-sectional study was conducted among undergraduate medical students from all study years at the Faculty of Medicine, University of Belgrade, during the 2015–2016 academic session. A questionnaire, composed of four parts, was administered to all participants: 1. socio-demographic characteristics; 2. habits and lifestyle; 3. Fagerstrom Test for Nicotine Dependence; 4. the Rosenberg self-esteem scale. Logistic regression analysis was conducted to identify the factors significantly associated with cigarette smoking. Results: A total of 2551 subjects, which constituted 81.8% of all undergraduate medical students, participated in the survey. The prevalence of current regular smokers among medical students was 21.7%. The results obtained using the Fagerstrom tolerance scale showed that 41.8% of the students had high nicotine dependence. According to the results of a multivariate analysis, the following were the independent determinants of being a smoker: being male, grade point average of <8/10, daily coffee consumption, self-reported excessive leisure time, self-reported pressure from parents, alcohol consumption, and smokers among parents. Conclusions: Understanding the factors influencing tobacco use is the first step in implementing prevention strategies and can be helpful in the cessation of smoking. © 2021 Taylor & Francis Group, LLC.
