title: Factors associated with the differences in migraine prevalence rates between Spanish regions.
abstract: We have analyzed the relation of prevalence rates in Spanish regions with a series of human, environmental, and ecological factors. We find that the variability in migraine rates found between Spanish regions may be explained by interregional differences in the percentage of daily smokers, percentage of alcohol consumers, percentage of population presenting physical and/or psychological life-limiting conditions, percentage of population engaging in physical exercise, minimum absolute temperatures per year, number of days under 0 °C per year, and altitude.
