Abstract
Los atlas de mortalidad publicados hasta la fecha son estáticos. La mayoría describen la distribución geográfica de la mortalidad agrupando datos de varios años y usando razones de mortalidad estandarizadas que resumen la mortalidad de todos los grupos de edad. Sin embargo, esta metodología presenta limitaciones para estudiar cambios temporales en la distribución geográfica de la mortalidad o diferencias entre grupos etarios. Aplicando una metodología alternativa surge el Atlas Interactivo de Mortalidad en Andalucía (AIMA), un Sistema de Información Geográfica dinámico que permite visualizar en web-site más de 12.000 mapas y 338.000 gráficos de tendencias correspondientes a la distribución espacio-temporal de las principales causas de muerte en Andalucía por grupos de edad y sexo desde 1981. El objetivo de este trabajo es describir la metodología utilizada para el desarrollo de AIMA, dar a conocer sus características y especificaciones técnicas y mostrar las posibilidades interactivas que ofrece. El sistema está disponible en el hipervínculo productos de www.demap.es. AIMA es el primer SIG interactivo de estas características implementado en España. Para el análisis de datos se han utilizado modelos jerárquicos bayesianos espacio-temporales, integrando posteriormente los resultados en web-site utilizando entorno PHP y cartografía dinámica en formato Flash. La selección de mapas temáticos muestra el carácter dinámico de la distribución geográfica de la mortalidad, con un patrón diferente para cada año, grupo de edad y sexo. La información contenida actualmente en este sistema y las futuras actualizaciones contribuirán a la reflexión sobre el pasado, presente y futuro de la salud en Andalucía.
Until now, mortality atlases have been static. Most of them describe the geographical distribution of mortality using count data aggregated over time and standardized mortality rates. However, this methodology has several limitations. Count data aggregated over time produce a bias in the estimation of death rates. Moreover, this practice difficult the study of temporal changes in geographical distribution of mortality. On the other hand, using standardized mortality hamper to check differences in mortality among groups. The Interactive Mortality Atlas in Andalusia (AIMA) is an alternative to conventional static atlases. It is a dynamic Geographical Information System that allows visualizing in web-site more than 12.000 maps and 338.00 graphics related to the spatio-temporal distribution of the main death causes in Andalusia by age and sex groups from 1981. The objective of this paper is to describe the methods used for AIMA development, to show technical specifications and to present their interactivity. The system is available from the link products in www.demap.es. AIMA is the first interactive GIS that have been developed in Spain with these characteristics. Spatio-temporal Hierarchical Bayesian Models were used for statistical data analysis. The results were integrated into web-site using a PHP environment and a dynamic cartography in Flash. Thematic maps in AIMA demonstrate that the geographical distribution of mortality is dynamic, with differences among year, age and sex groups. The information nowadays provided by AIMA and the future updating will contribute to reflect on the past, the present and the future of population health in Andalusia.
