Trends in Socioeconomic Inequalities in Ischemic Heart Disease Mortality in Small Areas of Nine Spanish Cities from 1996 to 2007 Using Smoothed ANOVA

The aim of this study was to analyze the evolution of socioeconomic inequalities in mortality due to ischemic heart diseases (IHD) in the census tracts of nine Spanish cities between the periods 1996–2001 and 2002–2007. Among women, there are socioeconomic inequalities in IHD mortality in the first period which tended to remain stable or even increase in the second period in most of the cities. Among men, in general, no socioeconomic inequalities have been detected for this cause in either of the periods. These results highlight the importance of intra-urban inequalities in mortality due to IHD and their evolution over time.This article has been partially funded by "Plan Nacional de I+D+I 2008-2011" and the "ISCIII-Subdirección General de Evaluación y Fomento de la Investigación" (project numbers: PI081488, PI081340, PI081017, PI081978, PI081713, and PI080330); Gobierno de Aragón (PI126/08); Fundación Canaria de Investigación Sanitaria FUNCIS 84/07; the project INEQ-CITIES, "Socioeconomic inequalities in mortality: evidence and policies of cities of Europe"; project funded by the Executive Agency for Health and Consumers (Commission of the European Union), project no. 2008 12 13; and by CIBER Epidemiología y Salud Pública (CIBERESP), Spain
