[Mortality due to ill-defined causes in Brazil (1979-2002) and a predictive model for age].

This study focused on the percentage of deaths due to ill-defined causes in Brazil, from 1979 to 2002. The objectives were to: (a) describe changes over the 24-year period; (b) identify the age group in which the percentage of ill-defined causes correlated most closely with the total percentage of ill-defined causes; (c) select a predictive model for the percentage of ill-defined causes in such age group, given the total percentage of ill-defined causes; (d) describe changes in the distributions of each age group in the total ill-defined causes; and (e) verify whether the percentage of deaths in-hospital shows any relationship to the percentage of ill-defined causes. Results showed that the total percentage of deaths from ill-defined causes decreased in Brazil.

[Dietary patterns associated with risk factors for cardiovascular disease in a Brazilian city].

Objective: To identify the dietary patterns of individuals living in the urban area of São Paulo, Brazil, and to investigate the association between these patterns and biological, sociodemographic, and behavioral risk factors for cardiovascular disease (CVD).

AIDS by mother-to-child transmission: survival analysis of cases followed from 1983 to 2002 in different regions of Brazil.

Antiretroviral therapy contributes to decreasing morbidity and mortality, and ultimately to increasing survival. In Brazil, there are regional differences in HIV epidemiology regarding pregnant women and children with HIV/AIDS. This study evaluates survival time after AIDS diagnosis in 914 children infected by mother-to-child transmission, reported between 1983 and 1998 and followed until 2002, in Brazil's five regions.

[Internal migration and distribution of Chagas disease mortality, Brazil, 1981-1998].

In Brazil, mortality from Chagas disease occurs even in regions classified as free of vector transmission. Because death rates refer to residents, and considering that a huge migratory movement has occurred inside the country, this study was intended to quantify the contribution of Brazilian internal migration to overall mortality from Chagas disease, from 1981 to 1998. If the PAHO Southern Cone Initiative actually achieved its objectives, one could expect declining death rates and increasing age at death from this cause.
