Use of health care services in childhood migraine.

The use of health care services in childhood migraine was studied in a representative population sample of 53 children with migraine. These children belong to a 1-year age cohort that has been followed since birth. Migraine was diagnosed at the age of 8 to 9 years according to the International Headache Society criteria of migraine in 95 of 3580 children (2.7%). At the time of the present study, 84 of the 95 children were clinically examined at the age of 11 to 13 years. Fifty-three of them (62.4%) still had migraine and 32 did not. Of these 53 children, 31 (51.8%) had consulted a doctor because of headache. The most important factors linked to the consultation rate were aura symptoms and maximal frequency of attacks. The children who had consulted a doctor more often had nausea and more often came from densely populated areas. They had missed school days more often because of headache than those who had not consulted a doctor.
