Migraine in adolescents
Abstract
OBJECTIVE: The influence of socioeconomic status on the prevalence of migraine is unknown in adolescents. Accordingly, we investigated the prevalence of migraine in a large sample of adolescents by sociodemographic features. METHODS: A validated headache questionnaire was mailed to 120,000 households representative of the US population. All individuals in the household were interviewed (probands and their parents). We calculated sex-specific prevalence estimates of migraine in adolescents derived by age, race, urban vs rural residence, household income, region of the country, and parental status of migraine, using log-linear models. RESULTS: A total of 32,015 adolescents were identified. Surveys were returned by 18,714 of them (58.4% response rate). The 1-year prevalence of migraine was 6.3% (5.0% in boys and 7.7% in girls). The prevalence was higher in girls than in boys older than 12 and in whites than African Americans. In families with an annual income lower than $22,500, the adjusted prevalence of migraine in adolescents without a parental history of migraine was 4.4%; in families earning $90,000 or more, it was 2.9% (OR = 0.49, 95% CI 0.38 to 0.63). In adolescents with a parental history of migraine, the prevalence in the lower vs the higher income group was 8.6% vs 8.4% (OR = 0.97, 0.81 to 1.15). CONCLUSIONS: In adolescents with family history of migraine, household income does not have a significant effect, probably because of the higher biologic predisposition. In…
