Estudo de fatores de risco para a mortalidade infantil no Rio Grande do Sul

Abstract

The aim of this study was to analyze the system data information of live births (SINASC) and mortality information system (SIM) to identify risk factors, for infant mortality of children born alive, by resident mothers in the state of Rio Grande do Sul, in 2008. For the analysis of the corresponding data, a longitudinal study was performed, using a multiple logistic regression model. In this study, the dependent variable was the occurrence or not of deaths in babies with less than a year of life. The adjustment results of the model indicate the significant risk factors (predictors) (p≤0,05) for infant mortality include the variables: gestational age (premature: OR=1,70), birth weight (0 to 499g: OR= 40, 46, 500 to 1499g: OR= 11,38 and 1500 to 2499g: OR= 1,64), Apgar score at 1st minute (≤7: OR=2,31), Apgar score at 5th minute (≤7: OR=5,85), male (OR=1,22), no prenatal consultation (OR=2,21), parity (>2 children, OR=1,40), mother's age (<20 years old, OR=1,12), mother's education (<4 years, OR=1,81) and congenital anomalies (with anomaly: OR= 17,92). This study enabled the use of the database of births and deaths, showing the main risk factors identification importance, as an aid in the strategies taken for improving the population health.
