The prevalence of headache disorders in children and adolescents in Benin: a schools-based study.

Background: A global schools-based programme within the Global Campaign against Headache is estimating the burden of headache in children (6-11 years) and adolescents (12-17 years), cluster-sampling the world by conducting national studies in all world regions. Its purpose is to complement population-based studies in adults, adding to knowledge of the burden of headache and informing educational and health policies. This study in Benin was the third in the programme from sub-Saharan Africa (SSA).
