[Perinatal mortality research in Brazil: review of methodology and results].
The perinatal mortality rate remains a public health problem, demanding epidemiological studies to describe its magnitude and time trends, identify risk factors, and define adequate interventions. There are still methodological controversies, resulting in heterogeneous studies and possible biases. In Brazil, there has been a growing scientific output on this theme, mainly in the South and Southeast of the country. Twenty-four articles from 1996 to 2003 were reviewed, focusing on definitions and classifications, data sources, study designs, measurement of variables, statistical analysis, and results. The review showed an increasing utilization of data bases (mainly SINASC and SIM), few studies on stillbirth, the incorporation of classification schemes, and disagreement concerning risk factors.
