dc.description.abstractNeonatal mortality still remains a complex challenge to be addressed. In Brazil, 60% of neonatal deaths occur among preterm infants with a gestational age of 32 weeks or less (≤32w). The aim of this study was to evaluate the factors involved in the high mortality rates among newborns with a gestational age ≤32w in a socioeconomically developed southern city in Brazil. Data on retrospective births and deaths (2000–2014) were analyzed from two ofcial Brazilian national databases. The risk of neonatal death for all independent variables (mother’s age and schooling, prenatal visits, birth hospital, delivery method, gestational age, and the newborn’s sex, age, and birth year, gemelarity, congenital anomalies and birthplace) was assessed with a univariable and a multivariable model of Cox’s semiparametric proportional hazards regression (p<0.05). Data of 288,904 newborns were included, being 4,514 with a gestational age ≤32w. The proportion of these early newborns remained stable among all births, while the neonatal mortality rate for this group tended to decrease (p<0.001). The adjusted risk was signifcantly for lower birthweight infants (mean 659.13g) born from Caesarean (HR 0.58 [95% CI 0.47–0.71]), but it was signifcantly higher for heavier birth weight infants (mean 2,087.79) also born via Caesarean section (HR 3.71 [95% CI 1.5–9.15]). Newborns with lower weight seemed to beneft most from Cesarean deliveries. Efort towards reducing unacceptably high surgical deliveries must take into account cases that the operations may be lifesaving for mother and/or the baby.en
