A Large-Scale Epidemiological Survey of Migraine Among School-Age Children and Adolescents in Southern Zhejiang and Northern Fujian, China: Prevalence, Clinical Profiles, and Risk Factors
Abstract
Abstract Objective To determine the prevalence, demographic distribution, attack characteristics, disease burden, and associated factors of migraine among school-aged children and adolescents in China. Methods This cross-sectional survey employed a stratified multistage random cluster sampling design across 26 schools in southern Zhejiang and northern Fujian. A validated structured questionnaire was administered on-site; suspected cases were independently diagnosed by two senior headache neurologists using ICHD-3 criteria and the Diagnostic Criteria for Vestibular Migraine of Childhood (VMC). Of 8,000 distributed questionnaires, 7,384 were valid (92.30% response rate; mean age 14.65 years). Chi-square tests, binary logistic regression, and multivariate logistic regression were used for analyses. Results The overall migraine prevalence was 7.04% (520/7,384). Vestibular migraine accounted for 1.63%, migraine with aura 1.19%, and migraine without aura 4.22%. Prevalence was significantly higher in females than males (9.06% vs. 5.15%, P 10 years (11.35%). Among migraineurs, most had 4–15 attack days/month (67.12%), 2–24 h duration (92.50%), and moderate pain (VAS 4–6, 76.92%). Over the preceding 3 months, mean academic impact was 4.38 days, headache-related leave was 1.42 days, missed social/leisure activities was 1.62 days, and family escort was 1.31 days—all showing a senior high > junior high > primary school gradient. Only 42.88% had ever sought medical care, and 37.31% were…
How strong is the evidence?
Evidence Hub reads this as a cross-sectional, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause.
