Epidemiology of migraine in the She ethnic minority group in Fujian province, China

Abstract

OBJECTIVES: We examined the prevalence and risk factors of migraine among the She population. The prevalence of migraine among She Chinese in Fujian province is high. METHODS: This study is a cross-sectional survey. Subjects completed a questionnaire that collected demographic and clinical data related to migraine. Physical examination and clinical laboratory tests were performed. Data were analyzed by regression analysis. RESULTS: Of the 5519 subjects enrolled, 2377 were male (43·1%) and 3142 female (56·9%). Of these, 581 (10·53%) experienced migraine annually, including 6·18% of males and 13·82% of females. Highest prevalence rate was among those aged 40-49 years (11·28%). The 141 (24·3%) subjects who had migraine with aura had higher incidence of family history of headache than those without aura (38·5% vs 19·9%, P < 0·0001). CONCLUSION: Female gender and insomnia are possible risk factors for migraine in the She population.
