Desigualdades socioeconómicas en la mortalidad en el País Vasco y sus capitales: Un análisis de áreas geográficas pequeñas (Proyecto MEDEA)

Abstract

Census track level socioeconomic inequalities in mortality are described in the Basque Country and its three main cities in the 1996-2003 period. An ecological crosssectional study of small areas was performed. Using principal component analysis a socioeconomic deprivation index was calculated. The mortality risk for each census track and the relation between mortality and socioeconomic deprivation were studied by means of hierarchical Bayesian models. Geographical patterns of the mortality risk and the deprivation index were similar, with higher mortality in more deprived areas. In the Basque Country as a whole the magnitude of the association between mortality and deprivation was higher in men than in women. In the cities, the association was only apparent for men. These results are useful to guide health policies and identify geographical areas with greater needs.
