Migraine is a relatively common disease that is associated with high disability and reduced quality-of-life. This study aimed to investigate the prevalence, epidemiological characteristics, and risk factors of migraine in Han Chinese from Fujian Province, China.A cross-sectional epidemiological survey study was conducted to evaluate characteristics of migraine in Han Chinese. Demographic and clinical data were collected through a survey administered in face-to-face interviews by trained investigators, and a physical exam and symptom review were performed. Univariate and multivariate regression analyses were performed to assess independent risk factors for migraine.A total of 7860 subjects aged 15 years and older were surveyed, of which 9.1% (n = 717) were diagnosed with migraine. Among these, a higher percentage was female (12.6%) than male (5.3%). Only 114 subjects (15.9%) were diagnosed as having migraine with aura, which was closely associated with family history of migraine. Multivariate regression analysis showed that the odds of migraine were significantly lower in subjects aged ≥50 years compared with those aged <30 years (odds ratio [OR] ranged from 0.40 to 0.64; P ≤.013) and was higher in females compared with males (OR = 2.89, P <.001). The odds of migraine was significantly greater in subjects with a history of alcohol consumption (OR = 1.81, P <.00) and insomnia (OR = 2.77, P <.001).Han Chinese in Fujian province has a relatively high prevalence of migraine, and female gender, <50 years of age, insomnia, and use of alcohol are associated with increased odds of having migraine in this population.
Background:The prevalence of migraines in the She population, a minority in China, is significantly higher than that in Han Chinese and other Asian populations. Two single nucleotide polymorphisms (SNPs) have been found to be associated with migraine susceptibility in the She population.Purpose: This study investigated four SNPs, identified in genome-wide association studies, within migraine-susceptible loci in Han Chinese for their association with migraine susceptibility in the She population.Methods: Two-hundred unrelated migraine patients and 200 healthy controls were recruited. The SNPs examined included rs2651899 (PRDM16 ), rs2274316 (MEF2D ), rs7577262 (TRPM8) and rs11172113 (LRP1). Genotyping of the SNPs was performed by allele-specific polymerase chain reaction and direct sequencing.Results: No significant differences between the participants with migraines and controls (participants without migraines) were demonstrated in genotypes, alleles and allele carriage frequencies for the four SNPs. A subgroup analysis found that migraine with aura had a lower frequency of C allele positivity in rs2651899 than in healthy controls (59.6% vs. 74.5%, respectively; P < 0.034). Univariate analyses indicated that no genotype of the four SNPs had a significant association with migraines. Males had a lower risk of migraines, and advanced age was a significant risk factor for migraines in females. Conclusion:The SNPs in four migraine susceptible loci in Han Chinese were not risk factors for migraines in a relatively small sample of the She population.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
