Objectives: To analyze the risk factors for neonatal death in Florianópolis, the Brazilian city
capital with the lowest infant mortality rate.
Method: Data were extracted from a historical cohort with 15,879 live births. A model was used
that included socioeconomic, behavioral, and health service use risk factors, as well as the Apgar
score and biological factors. Risk factors were analyzed by hierarchical logistic regression.
Results: Based on the multivariate analysis, socioeconomic factors showed no association with
death. Insufficient prenatal consultations showed an OR of 3.25 (95% CI: 1.70---6.48) for death.
Low birth weight (OR 8.42; 95% CI: 3.45---21.93); prematurity (OR 5.40; 95% CI: 2.22---13.88);
malformations (OR 4.42; 95% CI: 1.37---12.43); and low Apgar score at the first (OR 6.65; 95%
CI: 3.36---12.94) and at the fifth (OR 19.78; 95% CI: 9.12---44.50) minutes, were associated with
death.
Conclusion: Differing from other studies, socioeconomic conditions were not associated with
neonatal death. Insufficient prenatal consultations, low Apgar score, prematurity, low birth
weight, and malformations showed an association, reinforcing the importance of prenatal access
universalization and its integration with medium and high-complexity neonatal care services.
