Health conditions and residential concentration of poverty: a study in Rio de Janeiro, Brazil

摘要

Study objectives-To establish the geo- graphical relation of health conditions to socioeconomic status in the city of Rio de Janeiro, Brazil. Design-All reported deaths in the mu- Nicipality of Rio de Janeiro, from 1987 to 1995, obtained form the Mortality Infor- mation System, were considered din the study. The 24 "administrative regions" that compose the city were used as the geographical units. A geographical infor- mation system (GIS) was used to link mortality data and population census data, and allowed the authors to establish the geographical pattern of the health indicators considered in this study: "in- fant mortality rate"; "standardised mor- tality rate"; "life expecancy" and "homicide rate". Information on location of low income communities (slums) was also provided by the GIS. A varimax rota- tion principal component analysis com- bined information on socioeconomic conditions and provided a two dimension basis to assess contextual variation.
