Headache diagnosis, disability and co-morbidities in a multi-ethnic, heterogeneous paediatric Asian population.

This was a questionnaire survey on headache and migraine prevalence in 2873 Singaporean schoolchildren aged 6 to 16 years. ICHD-II headache classification, disability assessment with PedMIDAS and screening of psychosocial co-morbidities with the Paediatric Symptom Checklist were conducted. Lifetime headache prevalence was high at 80.6%, migraine prevalence was 8.6% and tension headache prevalence was 10.0%. Headache and migraine prevalence was high compared with that found in other Asian studies. Factors significantly associated with headache included adolescent age (OR = 1.5 [95% CI 1.3–1.9], p < .001), female gender at primary (OR = 1.4 [95% CI 1.1–1.8], p = .003) and secondary (OR = 1.8 [95% CI 1.3–2.5], p < .001) levels and Malay ethnicity at the primary level (OR = 2.8 [95% CI 1.6–4.9], p < .001). The average PedMIDAS score for headache disability was 3.2 ± 8.4, and migraine disability (PedMIDAS 8.1 ± 11.2–15.2 ± 29.6) was lower than in some studies. Self-medication (20.5%) and use of alternative the...
