Variation in migraine prevalence by race.

摘要: Purpose: Estimates of migraine prevalence from African and Asian populations are lower than those observed in European North American populations. To determine if these international differences reflect cultural, environmental, or genetic factors, we compared the among Caucasians, Americans, Americans United States. If factors predominate, racial should persist Methods: In Baltimore County, Maryland, 12,328 individuals 18 to 65 years age were selected by random-digit dialing interviewed telephone about their headaches. Migraine diagnoses assigned using International Headache Society criteria. Results: women, was significantly higher Caucasians (20.4%) (16.2%) (9.2%) Americans. A similar pattern men (8.6%, 7.2%, 4.2%). less likely report nausea vomiting with attacks, but more levels headache pain. contrast, tended be disabled attacks Caucasians. There no statistically significant associated features between Caucasian migraineurs. Conclusions: States, is highest followed While socioeconomic status, diet, symptom reporting may contribute estimated prevalence, suggest that race-related vulnerability predominate as an explanatory factor.
