Prevalence and Correlates of Migraine Among Women Attending a Prenatal Care Clinic in Lima, Peru

Abstract

Migraine headaches are among the leading causes of disability in the world. The burden of migraines is highest in women of reproductive age. This cross-sectional study characterized the prevalence, symptoms and correlates of migrainous headaches in 154 pregnant women attending a prenatal care clinic in Lima, Peru. Lifetime prevalence of migraine defined by modified IHS criteria was 9.1± (95± CI 4.6–13.6). When probable migraines were included, the lifetime prevalence of migraine in this population was 29.2± (95± CI 22.0–36.4). Migraine headaches were associated with a maternal history of headache, childhood carsickness, a diagnosis of allergies, and a high frequency of fatigue. Although headache-related disability was low in terms of missed work and recreation, high rates of headache pain and medicinal use reflect the true impact on this population.
