Abstract
To determine the prevalence and risk factors of migraine and headache among school children in Bangkok.
Methods: We carried out a community-based questionnaire survey, using the IHS diagnostic criteria, in 10 schools in Bangkok. The sensitivity and specificity of the questionnaire used in this study were 47.05% and 94.12% respectively. Two groups of school children, first and seventh grade students, were selected in order to determine the influence of age on the prevalence of migraine. The questionnaire also contained questions regarding risk factors such as family history of migraine, travelling time between school and home, mode of communication, school hours, and sleep duration at night.
Results: The response rates were 23.48% for the first grade students, and 100% for the seventh grade students. The prevalence of migraine in the 821 first grade students that responded was 0.37%, with 0.6% in boys and 0.3% in girls. From the total of 3,547 seventh grade students that were studied, there were 169 children (4.77%) who met the criteria of migraine by IHS, 58 males (3.11%) and 111 females (6.6%). Risk factors that increased the occurrence migraine were a positive family history of migraine, female sex, stress due to travelling time to school of more than 2 hours, and less sleeping time.
Conclusion: The prevalence of migraine of both age groups in this study was lower than studies from western countries. This could be due to a racial difference as well as the low sensitivity of the questionnaire. Besides the positive family history of migraine and less sleep duration at night, stress due to long hours of travelling between school and home was also an important triggering factor of migraine of school children in Bangkok.
