Prevalence and disability of headache among Norwegian adolescents: A cross-sectional school-based study

摘要

Background Headache is common in adolescents and affects schoolwork and relations with friends and family. In most previous epidemiological surveys, only the most bothersome headache has been documented. The aim was to determine headache prevalence not only taking into account the most bothersome headache, but also to compare characteristics of the most bothersome and less bothersome headaches, and to investigate headache-related disability.
