Clinical epidemiology of childhood abdominal migraine in an urban general practice

Abstract

The present study examined the epidemiology of abdominal migraine among 1104 children registered with a general practice. There was a similar prevalence of recurrent abdominal pain as in other studies (8.4 per cent). The prevalence of headache was higher among children with recurrent abdominal pain and significantly so among girls. Migrainous headache was not significantly more prevalent in children with recurrent abdominal pain. The prevalence of abdominal migraine with and without migrainous headache was 0.7 and 1.7 per cent, respectively. The peak prevalence of abdominal migraine without migrainous headache was between five and seven years for both sexes. When associated with migrainous headache, it peaked at five to seven years in girls and seven to nine years in boys. The syndrome was associated with travel sickness and was more common among girls and those with a maternal history of migraine. Many children were photo- and phonophobic during an attack.
