Prevalence and Awareness of Medication Overuse Headache among Undergraduate Students at the University of Belgrade

Abstract

Background: Medication overuse headache (MOH) is a prevalent and potentially preventable secondary headache disorder linked to the excessive use of medications intended for primary headache management, particularly migraine. Aim: The aim of our study was to assess the prevalence of MOH among undergraduate students and explore their awareness. Methodology: This observational cross-sectional study included 401 active undergraduate students from the University of Belgrade. Data were collected through an anonymous online questionnaire which was distributed among student groups and via social media. The questionnaire specially designed for this study was developed in accordance with established guidelines for headache epidemiological research. Results: Among the surveyed students, 10 of them (2.5%) met the criteria for the diagnosis of MOH. Awareness of MOH was noted in 149 (37.2%) students, with higher awareness among medical students and those aged 22–25 years. Despite this awareness, there was no significant difference in MOH occurrence between those aware and unaware of the condition (aware 2.7% vs. unaware 2.4%, p = 1.000). Additionally, significant gaps in education and communication about MOH were evident. Limitations: Participants were recruited through convenience sampling from a single university at one time point. The questionnaire was not specifically validated in the student population, and the data relied on self-reporting. Conclusions: Our study highlighted a notable prevalence of MOH among undergraduate students, with a substantial portion exhibiting awareness of its risks. Despite this awareness, our findings suggest ongoing gaps in education and communication regarding MOH, emphasizing the need for targeted interventions.
