[Time to kidney transplantation in chronic renal failure patients in the State of Rio de Janeiro, Brazil, 1998-2002].

This study analyzes the characteristics of 14,419 chronic renal failure patients treated with hemodialysis and time to first kidney transplantation in the State of Rio de Janeiro, Brazil, from 1998 to 2002. Survival analysis methods were used, such as the Kaplan-Meier non-parametric method and the semi-parametric method with the Cox proportional hazards model.

[Evaluation of quality of epidemiological and demographic variables in the Live Births Information System, 2002].

This study evaluates the quality of data in the Brazilian Live Births Information System (SINASC), focusing on the methodological clarity of documentation and adequate data completeness and consistency at the national, regional, and State levels in 2002. The variables analyzed were: skin color/race of newborn, maternal schooling, maternal marital status, maternal occupation, maternal age, prenatal visits, live births, stillbirths, and birth weight. For most of the variables, SINASC shows good data completeness and consistency, but there were serious problems with the quality of data on previous children and maternal occupation.

Progressive decline in stroke mortality in Brazil from 1980 to 1982, 1990 to 1992, and 2000 to 2002.

Background And Purpose: We describe the trends in stroke mortality in Brazil during 3 decades and investigate their differences according to regional disparities, sex, and age distributions.

Methods: Official data on mortality and population estimates were retrieved to calculate standardized mortality rates (with the 1980 Brazilian population as a reference) in 6 age strata and in the 5 political regions for the initial period (3 first years) of the 1980, 1990, and 2000 decades. Data were corrected for undefined causes of death.

[Consequences of sociodemographic inequalities on birth weight].

Objective: To analyze sociodemographic inequalities in prenatal and childbirth care and their consequences on birth weight.

Methods: The study was based on a sample of 10,072 postpartum women treated at public (those outsourced by the National Health System) and private maternity hospitals in Rio de Janeiro, Brazil, from 1999 to 2001. To test the association between birth weight and maternal sociodemographic and biological characteristics and prenatal care (modified Kotelchuck index), postpartum women were stratified by level of schooling and two multiple linear regressions were performed.

[Reliability of birth certificate data in Rio de Janeiro, Brazil, 1999-2001].

The objective of this article is to assess coverage and reliability of data from the Information System on Live Births in the City of Rio de Janeiro, based on an analysis of live birth certificates issued by the various hospitals and compared to information from the "Study on Neonatal and Perinatal Morbidity and Mortality and Care in the City of Rio de Janeiro". A total of 9,608 interviews with post-partum women were paired case-by-case with the respective birth certificates.
