Abstract
OBJECTIVES: To establish the profile of neonates in Caxias do Sul city, and to study early neonatal mortality, its causes and related variables.METHODS: This cohort study enrolled 5,545 newborns, which were followed up to 7 days after birth. The probability of early neonatal mortality was calculated and multiple logistic regression was performed to relate all studied variables to the outcome of early neonatal death.RESULTS: The observed probability of early neonatal mortality was 7.44 per thousand live births. The incidence of premature births and low birth weight was 9.4% and 8.1%, respectively. Fifty five percent of the neonates were born through cesarean section, which were related to socioeconomic and educational level. Previous history of neonatal mortality, maternal age > 35 years, gestational age, Apgar score < 7, male sex and low birth weight were related to early neonatal death. The main cause of death was hyaline membrane disease, followed by congenital cardiopaties, extreme preterm and abruptio placentae.CONCLUSION: Even though the observed probability of early neonatal mortality was low, some deaths may have been avoided if better prenatal and delivery care, as well as newborn assistance had been offered.
