Do socioeconomic inequalities in mortality vary between different Spanish cities? a pooled cross-sectional analysis

Background: The relationship between deprivation and mortality in urban settings is well established. This relationship has been found for several causes of death in Spanish cities in independent analyses (the MEDEA project). However, no joint analysis which pools the strength of this relationship across several cities has ever been undertaken. Such an analysis would determine, if appropriate, a joint relationship by linking the associations found. Methods: A pooled cross-sectional analysis of the data from the MEDEA project has been carried out for each of the causes of death studied. Specifically, a meta-analysis has been carried out to pool the relative risks in eleven Spanish cities. Different deprivation-mortality relationships across the cities are considered in the analysis (fixed and random effects models). The size of the cities is also considered as a possible factor explaining differences between cities. Results: Twenty studies have been carried out for different combinations of sex and causes of death. For nine of them (men: prostate cancer, diabetes, mental illnesses, Alzheimer’s disease, cerebrovascular disease; women: diabetes, mental illnesses, respiratory diseases, cirrhosis) no differences were found between cities in the effect of deprivation on mortality; in four cases (men: respiratory diseases, all causes of mortality; women: breast cancer, Alzheimer’s disease) differences not associated with the size of the city have been determined; in two cases (men: cirrhosis; women: lung cancer) differences strictly linked to the size of the city have been determined, and in five cases (men: lung cancer, ischaemic heart disease; women: ischaemic heart disease, cerebrovascular diseases, all causes of mortality) both kinds of differences have been found. Except for lung cancer in women, every significant relationship between deprivation and mortality goes in the same direction: deprivation increases mortality. Variability in the relative risks across cities was found for general mortality for both sexes. Conclusions: This study provides a general overview of the relationship between deprivation and mortality for a sample of large Spanish cities combined. This joint study allows the exploration of and, if appropriate, the quantification of the variability in that relationship for the set of cities considered.

Mortalidad evitable y políticas en salud: Colombia, 1985-2002

Introducción: La confianza en la capacidad de evitar algunas muertes o diferir su aparición es el fundamento de toda política de salud, uno de cuyos principales resultados debe ser reducir las muertes evitables, y controlar las condiciones que aumentan el riesgo de morir. Objetivos: Establecer variaciones en la tendencia de la mortalidad evitable (ME) registrada en Colombia entre 1985 y 2002, como indicadoras del impacto efectivo que las reformas en la política sanitaria pudieran haber tenido sobre sus determinantes. Métodos: Estudio de la ME con base en los registros oficiales de defunción y en las proyecciones censales de Colombia entre 1985-2002. Para determinar la evitabilidad, se aplicó un inventario de causas de ME (ICME) ajustado a las condiciones epidemiológicas del país durante el período que se analiza. Resultados: De las muertes registradas, 75.3% se clasificaron como evitables. Se identificaron siete patrones de tendencia que reflejan, de manera particular, los efectos de las políticas públicas sobre los determinantes de la mortalidad. Conclusiones: En general, la ME viene disminuyendo en Colombia desde 1985 en la población general y entre los hombres, sin variaciones significativas durante el período. Las variaciones en la tendencia de las tasas ajustadas de varios grupos de causas hacen pensar en un deterioro en el control de sus determinantes, especialmente desde 1990. Los cambios aplicados en las políticas públicas durante los últimos años no se reflejaron en un mejor control de las muertes evitables, aunque el gasto en salud aumentó de modo muy notable en el país.
