Objective:
To collect and analyse epidemiological data on childhood headache in the Hong Kong community.
Design:
Questionnaire study.
Setting:
Three primary schools, Hong Kong.
Participants:
Two thousand, one hundred and twenty pupils from 2156 replied to the questionnaire survey. One hundred and twenty-four pupils who were identified to have suspected recurrent headache were invited to a follow-up medical consultation.
Main Outcome Measures:
Age-groups and prevalence of tension-type and migraine headache, using the diagnostic criteria of the International Headache Society.
Results:
The overall prevalence of headache in the 2120 respondents was 2.8%. The prevalence of tension-type headache, migraine, probable migraine, and unclassified headache were 1.2%, 0.5%, 0.7%, and 0.5%, respectively. The age-specific prevalence of headache from the age of 6 to 13 years showed a steadily increasing trend from childhood to the early teens.
Conclusion:
Headache is a common complaint for children, although it may be underrecognised. Further study will be beneficial for providing better management of headache in this population.
