Prevalence of Migraine and its associated factors among medical students of Bangladesh: A cross sectional study

IntroductionMedical students are vulnerable group to migraine, one of the most common type of headache worldwide. The aim of the present study was to determine the prevalence of migraine and related disability among medical students of Bangladesh. MethodsThis cross-sectional study was conducted among 1327 students from six medical colleges Bangladesh during March 2021 through a self-administered online survey. ID Migraine scale and MIDAS scale were used to screen migraine and migraine related disability respectively. Frequency distribution, and Chi-square test, t-test along with multiple logistic regressions model were used to determine the prevalence and associated factors of migraine respectively. ResultsThe overall prevalence of migraine among the participants was 19%. The prevalence was higher among females (27%) than males (8%). Female sex (aOR 4.11, 95% CI 2.79-6.03) and poor sleep quality (aOR 2.07, 95% CI 1.48-2.91) were identified as independent risk factors of migraine. More than 90% migrainures reported to suffer from moderate to severe headache. Nausea was most commonly reported associated symptom (83.5%) followed by photophobia (72%) and vomiting (53%). Self-reported mental stress (55%), irregular sleep (49%), noise (30.5%), and usage of electronic device (30.5%) were most commonly reported triggering factor of migraine attack. More than half of the sufferers reported severe migraine related disability (MIDAS score [≥] 21). ConclusionsThe prevalence of migraine among medical students of Bangladesh is alarmingly high. Frequent migraine attacks and severe intensity of headache cause a substantial level of disability among the sufferers. Cautious avoidance of the triggering factors through appropriate interventions and prophylactic medication can mitigate the negative impact of migraine as well as improve the quality of life.
