Evolución de la incidencia de migraña en Álava en el período 2004-2008 / Evolution of the incidence of migraine in Álava over the period 2004-2008

Introducción. Existen muy pocos estudios sobre la incidencia de migraña en España, y los que hay tienen alguna limitación, como carecer de base poblacional clara. Objetivo. Examinar la evolución de la incidencia de migraña a lo largo del período 2004-2008 en la provincia de Álava (País Vasco, España).Pacientes y métodos. Los datos corresponden a personas de 15 o más años de edad registrados como nuevos casos diagnosticados de migraña en la base de datos del Servicio Vasco de Salud/Osakidetza. La tendencia en la incidencia de migraña se valoró mediante regresión lineal. Resultados. La incidencia de migraña fue significativamente mayor en las mujeres que en los hombres, a cualquier edad. No se observaron cambios en la incidencia de migraña en el período 2004-2008 en el conjunto de la población de Álava (p = 0,189). Sin embargo, se ha producido un descenso en la incidencia de migraña en las mujeres mayores de 64 años (p = 0,014), y un aumento en las de 15-24 años (p = 0,052) y 35-44 años (p = 0,057). Los nuevos casos de migrañadiagnosticada tendieron a aparecer en edades más jóvenes a lo largo de este período. Conclusiones. Estos resultados indican una ausencia de cambios en la tendencia de la incidencia de migraña a lo largo del período 2004-2008, excepto un descenso en el caso de las mujeres mayores de 64 años y un aumento en las jóvenes. Esta evolución es similar a la de otras regiones europeas (AU)

Introduction. Few studies have been conducted on the incidence of migraine in Spain, and those that have been carried out have some shortcomings, such as the lack of a clear population base. Aims. To examine the evolution of the incidence of migraine over the period 2004-2008 in the province of Álava (Basque Country, Spain).Patients and methods. Data concerned persons aged 15 or over who were registered in the Basque Health Service/Osakidetza database as new cases diagnosed with migraine. The tendency of the incidence of migraine was evaluated by means oflinear regression. Results. The incidence of migraine was significantly higher in females than in males, at any age. No significant changes in the incidence of migraine were observed over the period 2004-2008 in the population of Ávala as a whole (p = 0.189). Nevertheless, there have been both a decrease in the incidence of migraine in females over the age of 64 (p = 0.014) and an increase in those aged 15-24 years (p = 0.052) and 35-44 years (p = 0.057). The new cases of migraine that arediagnosed tended to appear at younger ages over this period. Conclusions. These results suggest an absence of changes in the tendency in the incidence of migraine throughout the period 2004-2008, except for a decrease in the case of females over 64 years of age and an increase in young females.This evolution is similar to that of other regions in Europe (AU)

INTRODUCTION: Few studies have been conducted on the incidence of migraine in Spain, and those that have been carried out have some shortcomings, such as the lack of a clear population base. AIMS: To examine the evolution of the incidence of migraine over the period 2004-2008 in the province of Álava (Basque Country, Spain). PATIENTS AND METHODS: Data concerned persons aged 15 or over who were registered in the Basque Health Service/Osakidetza database as new cases diagnosed with migraine. The tendency of the incidence of migraine was evaluated by means of linear regression. RESULTS: The incidence of migraine was significantly higher in females than in males, at any age. No significant changes in the incidence of migraine were observed over the period 2004-2008 in the population of Ávala as a whole (p = 0.189).

CONCLUSIONS: These results suggest an absence of changes in the tendency in the incidence of migraine throughout the period 2004-2008, except for a decrease in the case of females over 64 years of age and an increase in young females. This evolution is similar to that of other regions in Europe.
