This study examined the prevalence and impact of migraine in the United States. Data was collected using a self-administered questionnaire sent to 20,000 households. The response rate was 68.3% among 43,527 eligible individuals. Among respondents, 18% of females and 7% of males reported migraines. About 23% of households had at least one migraine sufferer. Prevalence was higher in whites compared to blacks and decreased with income. Migraine rates rose from age 12 to around age 40, then declined. More than half of respondents experienced significant impairment due to migraines. Approximately 31% missed at least one day of work or school in three months. Additionally, 51% reported reduced productivity due to migraines. The study found stable prevalence rates over the last decade. The number of migraineurs increased from 23.6 million in 1989 to 27.9 million in 1999. Migraine remains a public health challenge due to its substantial burden. Clinical relevance: This study highlights the widespread impact of migraine, emphasizing the need for effective public health strategies.
