RESUMO
This study aimed to identify factors associated with in-hospital mortality in High-Risk Neonatal Units (NICU) belonging to the North-Northeast Perinatal Health Network in Northeast Brazil. The explanatory variables were individual maternal characteristics, prenatal care, childbirth and neonatal care, and infant characteristics. This was a longitudinal, multicenter hospital-based study. The study population consisted of 3,623 live born infants admitted to 34 NICUs. After adjusting for the three hierarchical levels in the model for determination of death in the NICU up to the 27 th day of life, the following showed statistically significant association: type of delivery - cesarean section (OR = 0.72; 95%CI: 0.56-0.95), non-use of prenatal steroids (OR =1.51; 95%CI: 1.01-2.25), preeclampsia (OR = 0.73; 95%CI: 0.56-0.95), oligohydramnios (OR = 1.57; 95%CI: 1, 17-2.10), birth weight < 2500g (OR = 1.40; 95%CI: 1.03-1.90), 5-minute Apgar score < 7 (OR = 2.63; 95%CI: 2.21-3.14), endotracheal intubation (OR = 1.95; 95%CI: 1.31-2.91), and non-use of surfactant (OR = 0.54; 95%CI: 0.43-0.69). Death during NICU care is determined by conditions of the pregnancy, childbirth, and the newborn.

Este estudo pretendeu determinar os fatores associados à mortalidade intra-hospitalar, utilizando como variáveis explicativas as características individuais da mãe, da assistência ao pré-natal, parto e período neonatal e dos recém-nascidos internados em Unidades Neonatais de Alto Risco (UTIN) integrantes da Rede Norte-Nordeste de Saúde Perinatal no Nordeste do Brasil. Foi realizado estudo longitudinal, multicêntrico de base hospitalar. A população do estudo compreendeu 3.623 nascidos vivos internados em 34 UTIN. Após o ajuste para os três níveis hierárquicos do modelo de determinação do óbito em UTIN até o 27 o dia de vida, associaram-se: tipo de parto – cesariana (OR = 0,72; IC95%: 0,56-0,95); não uso de corticoide antenatal (OR = 1,51; IC95%: 1,01-2,25); pré-eclâmpsia (OR = 0,73; IC95%: 0,56-0,95); oligodramnia (OR = 1,57; IC95%: 1,17-2,10); peso ao nascer < 2.500g (OR = 1,40; IC95%: 1,03-1,90); escore de Apgar 5 o minuto < 7 (OR = 2,63; IC95%: 2,21-3,14); uso de tubo endotraqueal (OR = 1,95; IC95%: 1,31-2,91); não uso de surfactante (OR = 0,54; IC95%: 0,43-0,69). O óbito em UTIN é determinado pelas condições assistenciais à gestação, parto e recém-nato.

Este estudio tuvo como objetivo determinar los factores asociados a la mortalidad hospitalaria, utilizando como variables explicativas las características individuales de la madre, la atención prenatal, el parto y los bebés recién nacidos internados en Unidades Neonatales de Alto Riesgo (UCIN), miembros de la red norte-noreste de salud perinatal en el noreste de Brasil. Fue realizado estudio longitudinal, multicéntrico basado en el hospital. La población de estudio incluyó 3.623 nacidos vivos admitidos en 34 UCIN. Después de ajustar los tres niveles jerárquicos para la determinación del modelo de muerte en la UCI neonatal hasta los 27 días de vida, se les asociaba un tipo de parto: cesárea (OR = 0,72; IC95%: 0,56-0,95); uso de corticosteroides prenatales (OR = 1,51; IC95%: 1,01-2,25); preeclampsia (OR = 0,73; IC95%: 0,56-0,95); oligohidramnios (OR = 1,57; IC95%: 1,17-2,10); peso al nacer < 2.500g (OR = 1.40; IC95%: 1,03-1,90); Apgar 5 minutos < 7 (OR = 2,63; IC95%: 2.21-3.14); intubación endotraqueal (OR = 1,95; IC95%: 1,31-2,91); uso de surfactante (OR = 0,54; IC95%: 0,43-0,69). La muerte durante el cuidado en una UCIN está determinada por las condiciones durante el embarazo, el parto y el recién nacido.

BACKGROUND: Child undernutrition affects millions of children globally. We investigated associations between suboptimal growth and mortality by pooling large studies. METHODS: Pooled analysis involving children 1 week to 59 months old in 10 prospective studies in Africa, Asia and South America. Utilizing most recent measurements, we calculated weight-for-age, height/length-for-age and weight-for-height/length Z scores, applying 2006 WHO Standards and the 1977 NCHS/WHO Reference. We estimated all-cause and cause-specific mortality hazard ratios (HR) using proportional hazards models comparing children with mild (-2≤Z<-1), moderate (-3≤Z<-2), or severe (Z<-3) anthropometric deficits with the reference category (Z≥-1). RESULTS: 53 809 children were eligible for this re-analysis and contributed a total of 55 359 person-years, during which 1315 deaths were observed. All degrees of underweight, stunting and wasting were associated with significantly higher mortality. The strength of association increased monotonically as Z scores decreased. Pooled mortality HR was 1.52 (95% Confidence Interval 1.28, 1.81) for mild underweight; 2.63 (2.20, 3.14) for moderate underweight; and 9.40 (8.02, 11.03) for severe underweight. Wasting was a stronger determinant of mortality than stunting or underweight. Mortality HR for severe wasting was 11.63 (9.84, 13.76) compared with 5.48 (4.62, 6.50) for severe stunting. Using older NCHS standards resulted in larger HRs compared with WHO standards. In cause-specific analyses, all degrees of anthropometric deficits increased the hazards of dying from respiratory tract infections and diarrheal diseases. The study had insufficient power to precisely estimate effects of undernutrition on malaria mortality. CONCLUSIONS: All degrees of anthropometric deficits are associated with increased risk of under-five mortality using the 2006 WHO Standards. Even mild deficits substantially increase mortality, especially from infectious diseases.
