Objectives: This study has been aimed at evaluating knowledge, attitudes and behaviour of university students regarding the usage of antibiotics focusing on differences between medical and nonmedical students.
Methods: This cross-sectional questionnaire-based study was performed on 800 students of the University of Novi Sad, Serbia.
Results: The identified predictors of adequate antibiotic knowledge were enrolled in medical program, higher grade average and appropriate use of antibiotics during last infection. Multivariate regression identified following predictors of self-medication: being medical student (B = 0.715; p < 0.001), more frequent (B = 0.628; p < 0.001) and irregular (B = 0.584; p = 0.001) antibiotic use, a family member engaged in medical profession (B = 0.789; p < 0.001), living in dormitory (B = 0.679; p = 0.007) or rented apartment (B = 0.621; p = 0.002), using antibiotics until symptoms resolved (B = 1.616; p < 0.001) or until the bottle was finished (B = 0.628; p < 0.001) during the last infection.
Conclusions: Although a high number of students showed adequate knowledge about antibiotics, numerous misconceptions were recorded, including self-medication. Further educational interventions are necessary to improve their understanding, perceptions as well as their behaviour towards antibiotic use.
