title: Comorbidity of other pains in schoolchildren with migraine or nonmigrainous headache.
abstract: OBJECTIVE
  To compare the occurrence of pain other than headache in prepubertal children with migraine and those with nonmigrainous headache.
  
  
  METHODS
  An unselected population-based prospective follow-up study on the occurrence of headache in school-aged children was carried out in 1290 children aged 8 to 9 years. The children (n = 725) who reported headache during the preceding 6 months were sent a more detailed questionnaire concerning the occurrence of pain other than headaches; 622 children (86%) returned an acceptably completed second questionnaire. Of them, 53 (8.5%) had migraine. Nonmigrainous headache was found in 460 children (74%).
  
  
  RESULTS
  Children with migraine reported neck-shoulder pain, abdominal pain, back pain, and otalgia significantly more often than those with nonmigrainous headache. The median of the sum of other pains in children with migraine was significantly higher than that in children with nonmigrainous headache. The sum of other pains correlated positively with the frequency of nonmigrainous headache episodes (r =.40; 95% CI.31-.47), but there was no correlation between the sum of other pains and frequency of migraine attacks (r = -0.09; 95% CI -0.36-0.20).
  
  
  CONCLUSIONS
  Children with migraine are more likely to report types of pain other than headaches, regardless of the frequency of attacks. Children with frequent nonmigrainous headaches also report higher frequencies of other types of pain.
