“…Research that evaluate perinatal factors associated with early death in preterm infants born in eight public university hospitals affiliated with the Brazilian Neonatal Research Network found that the Apgar score between 0 and 6 at the 5 th minute was strongly associated with early neonatal death (16) . This finding is confirmed by other studies, highlighting a study conducted in the USA, which showed higher correlation between low Apgar score at the 5 th minute (0 to 6) and neonatal mortality in preterm infants with gestational age of 24 to 28 weeks (17) , association also observed in this study (OR=5.72).…”

Objective To evaluate the factors associated with neonatal mortality in infant born with low birth weight. Method Cross-sectional study that analyzed data from 771 live births with low birth weight (<2500 g) in the city of Cuiabá, MT, in 2010, of whom 54 died in the neonatal period. We obtained data from the Information System on Live Births and Mortality, by integrated linkage. Results In multiple logistic regression, neonatal mortality was associated with: number of prenatal visits less than 7 (OR=3.80;CI:1,66-8,70); gestational age less than 37 weeks (OR=4.77;CI:1.48-15.38), Apgar score less than 7 at the 1st minute (OR=4.25;CI:1.84-9.81) and the 5th minute (OR=5.72,CI:2.24-14.60) and presence of congenital anomaly (OR=14.39;IC:2.72-76.09). Conclusion Neonatal mortality in infants with low birth weight is associated with avoidable factors through adequate attention to prenatal care, childbirth and infants.

“…The highest rates of perinatal mortality were confi rmed in other studies conducted in diff erent Brazilian states (8,9,15,17) . These results did not diff er from other studies conducted in La n America, Europe and USA (16,(18)(19)(20) . In the United Kingdom in 2010, the highest rates of neonatal mortality were related to low birth weight and gesta onal age less than 31 weeks (21) .…”

“…In the U.S.A., the rela onship between Apgar score and neonatal mortality of preterm newborns, between 2001 and 2002, showed that the increased risk of neonatal anoxia (score 0-6) occurred among newborns with gesta onal age of 24-28 weeks (average of 6). In pregnancies with 30 to 36 weeks, the mean Apgar score was nine (no anoxia) (19) .…”

RESUMO ABSTRACTThis is an ecological quantitative study to identify risk factors that determined neonatal death between the years of 2000 to 2009 in Londrina, Paraná, using data from Birth Cer fi cates, Death Cer fi cates and Infant Death Inves ga on Forms. The variables maternal age, years of educa on, family income, occupa on, marital status, type of delivery, and number of prenatal appointments were not associated to neonatal death. To the contrary, birth weight, gestational age, Apgar score at 1 and 5 minutes, and place of birth were iden fi ed as sta s cally signifi cant variables. More than 73.0% of newborns died within early neonatal period. The predominant basic cause of death was perinatal problems (77.7%), 72.6% of which were preventable, and the majority of which could be reduced with adequate control over pregnancy/ birth. These results highlight the need for investments in prevention of premature delivery by improvement of health care in prenatal and birth periods, in an equanimous, accessible and comprehensive manner in all levels of maternal and child health care. DESCRIPTORS Infant mortality Risk factors Cause of death Neonatal nursing Ecological studies RESUMENInves gación cuan ta va de po ecológico objetivando identificar los factores de riesgo que determinaron el deceso neonatal en el municipio de LondrinaParaná entre 2000 y 2009. Se verificó que la edad materna, escolaridad, renta familiar, ocupación, situación conyugal, tipo de parto y número de consultas prenatales no se asocian al fallecimiento. Mientras tanto, el peso al nacer, la edad gestacional, el índice de Apgar en los minutos 1 y 5 y el lugar del parto sí mostraron significatividad estadística. Más del 73,0% de los recién nacidos fallecieron en el período neonatal precoz. La causa predominante fue afección perinatal (77,7%), considerándose que 72,6% de las muertes fueron evitables, y la mayoría, reducible por control adecuado del embarazo y parto. Tales resultados refuerzan la necesidad de inversiones en prevención del parto prematuro con atención prenatal y al parto equita vo, accesible e integral entre los diferentes niveles de atención de la salud materno-infan l.

“…42 In our study, birth in high-activity regions was associated with a reduced risk of being born in poor condition, as measured by the Apgar scores; low Apgar scores indicate a more pronounced fetal compromise and are associated with poor outcome. 29,43 When analyzed by GA groups, all risk reductions were confined to the 22-to 24-week GA group. Among infants born alive at 22 to 24 weeks, the 1-year mortality rate was 35% in highactivity regions and 59% in lowactivity regions.…”

, for the EXPRESS Study Group abstract OBJECTIVE: To examine the association between intensity of perinatal care and outcome at 2.5 years' corrected age (CA) in extremely preterm (EPT) infants (,27 weeks) born in Sweden during 2004-2007. METHODS: A national prospective study in 844 fetuses who were alive at the mother's admission for delivery: 707 were live born, 137 were stillborn. Infants were assigned a perinatal activity score on the basis of the intensity of care (rates of key perinatal interventions) in the infant's region of birth. Scores were calculated separately for each gestational week (gestational age [GA]-specific scores) and for the aggregated cohort (aggregated activity scores). Primary outcomes were 1-year mortality and death or neurodevelopmental disability (NDI) at 2.5 years' CA in fetuses who were alive at the mother's admission. In health care regions with higher aggregated activity scores, the risk of death or NDI at 2.5 years' CA was reduced in the primary population (aOR: 0.69; 95% CI: 0.50-0.96) and in live-born infants (aOR: 0.68; 95% CI: 0.48-0.95). Risk reductions were confined to the 22-to 24-week group. There was no difference in NDI risk between survivors at 2.5 years' CA.CONCLUSIONS: Proactive perinatal care decreased mortality without increasing the risk of NDI at 2.5 years' CA in EPT infants. A proactive approach based on optimistic expectations of a favorable outcome is justified.
