Abstract
Objectives
The aim of this study was to evaluate the prevalence and patterns of beta-blocker usage among medical students. Reasons for the use and demographic factors influencing their consumption were also evaluated.
Methods
This was an observational cross-sectional study among medical students at King Saud bin Abdulaziz University for Health Sciences (KSAU-HS) Jeddah, Saudi Arabia. Medical students were surveyed between February and April of 2019 using an electronic self-administered questionnaire. The questionnaire had close-ended questions, 18 of which were about demographics and 17 about propranolol use.
Results
A total of 234 medical students participated in the study, of whom 14.5% (95% CI: 10.44-19.49) reported using propranolol. Fifth-year medical students comprised 50% of propranolol users. The prevalence of males using propranolol was lower compared to females. The most common reasons for using propranolol were anxiety relief and performance enhancement before the objective structured clinical exams (OSCE5; 70.6%) and before oral presentations (38.2%).
Conclusion
The prevalence of propranolol use among medical students in KSAU-HS Jeddah was low compared to other studies, with the highest reported use among fifth-year medical students. The main reasons for using propranolol were anxiety relief during OSCEs and performance enhancement for presentations. Efforts must be directed towards raising medical students' awareness of the risks of inappropriate beta-blocker use to decrease its use and avoid potential adverse effects of the medication.
