Abstract
Background: Alcohol, smoking, and substance use among medical students are significant health concerns that impact their well-being and their future roles as health advocates. This study aimed to investigate the prevalence of these behaviors and related risk factors among medical students in southern Iran.
Methods: This cross-sectional study was conducted among medical students in Shiraz, in southern Iran, in 2024. Data were collected using the World Health Organization’s alcohol, smoking, and substance involvement screening test (ASSIST), supplemented with questions on demographic details, family and friend substance use, mental health, and major satisfaction. The sample was selected using the stratified random selection method. Logistic regression models were used to identify factors associated with substance use, controlling for potential confounders. P<0.05 was considered statistically significant. All analyses were performed using SPSS software (version 26, SPSS Inc., USA).
Results: The study included 360 medical students, of whom 51.9% were men, with a mean age of 22.62±3.02 years. The lifetime prevalence was 27.5% for alcoholic beverages, 26.7% for tobacco products, 14.4% for sedatives or sleeping pills, and 15.8% for electronic cigarettes and vapes. Logistic regressions analysis revealed that having a family member who uses substances (OR=1.8, 95% CI:1.01-3.5), having a friend who uses substances (OR=3.9, 95% CI: 2.0-7.8), being male (OR=1.8, 95% CI: 1.03-3.2), and having a recent history of mental illnesses (OR=2.8, 95% CI: 1.1-7.1) were positively associated with lifetime cigarette use.
Conclusion: The prevalence of alcohol, smoking, and substance use among medical students in southern Iran is concerning. These findings emphasized the significance of targeted interventions to reduce and prevent use within this population.
