Prevalence of migraine in Iran: a systematic review and meta-analysis

Abstract

Background Migraine headaches affect all ages, from childhood to old age. Migraine attacks cause significant changes in the living conditions of the sick person, including a decrease in personal, social, and occupational performance. This study was conducted to determine the prevalence of migraine in Iran through a systematic review and meta-analysis. Method In this systematic review and meta-analysis study, the studies associated with the prevalence of migraine using the keywords: migraine, prevalence, and Iran its equivalents in international databases PubMed, Web of Science, Scopus, Science direct, and Iranian internal information databases, including SID and MagIran, was searched without limit until November 2022. Comprehensive Meta-Analysis software (Version 2) was used to analyze the data. Due to the high number of studies reviewed in this systematic review, the Begg and Mazumdar test was used at a significance level of 0.1, and the corresponding Funnel plot was used to check publication bias. Also, the I2 test was used to check the heterogeneity in this study. Results 22 records were included in the final analysis. The prevalence of migraine in the general population of Iran was 15.1% (confidence interval 95%: 10.7–20.9), and in this population, the prevalence of migraine was higher in women than in men. The prevalence of migraine based on The International Classification of Headache Disorders (ICHD) 2 criteria was reportedly 16.4% (95% CI: 10.8–24.1), and with ICHD3 criteria, this value was reported as 17.1% (95% CI: 7.7–33.6). Based on a survey of 4571 children, the prevalence of migraine was reported to be 5.2% (95% CI: 1.3–18.7). Also, the prevalence of migraine in adolescents was calculated based on eight studies (n = 8820). Accordingly, 11.2% (95% CI: 5.8–20.4) of adolescents have migraines. Meanwhile, the prevalence of migraine in boys was 8.2% (95% CI: 4.8–13.7), and in girls was 8% (95% CI: 6.2–12.7). Conclusion As a result, the prevalence of migraine in Iran, based on population-based studies, was reported as 15.1%. The result showed a higher prevalence of migraine in the general population than in children and adolescents. It was also found that the prevalence of migraine in women is higher than in men.

The effect of selenium supplementation on oxidative stress, clinical and physiological symptoms in patients with migraine: a double-blinded randomized clinical trial

“…Migraine is a prevalent, disabling neurological disorder with a prevalence of 14-15% worldwide (8) and 15.1% in Iran (9). Migraine is characterized by moderate-to-severe, unilateral, and throbbing headaches, which often last between 4 and 72 h, along with photophobia, phonophobia, vomiting, and nausea (10).…”
