Objective. To estimate magnitude and determinants of neonatal and post-neonatal mortality rates in Goiânia, Brazil, 2012. Methods.  Retrospective cohort study, using linkage of Live Births Information System and Mortality Information System. It has been used logistic regression to evaluate neonatal e post-neonatal death associated factors. Results. Neonatal mortality (0-27 days of life) was 9.4; and post-neonatal (28-364 days of life) was 3.0 deaths per 1,000 live births. Neonatal mortality associated factors were: 0-3 prenatal care visits (OR=13.10 – CI95% 7.48;22.96), 19-34-week pregnancy (OR=6.25 – CI95% 2.26;17.29), weight at birth <1,500g (OR=62.42 – CI95% 22.72;171.48) and cesarean delivery (OR=0.54 – CI95% 0.37;0.79). For post-neonatal period they were: 0-3 prenatal appointments (OR=4.16 – CI95% 1.51;11.43) and weight at birth <1.500g (OR=18.74 – CI95% 4.04;87.00). Conclusion: Low number of prenatal care visits, premature delivery and low weight at birth were the main determinants of neonatal and post-neonatal mortality.
