Risk factors for neonatal death in an inland region in the State of São Paulo Brazil.

Abstract：

:The main objective of this study was to identify risk factors for neonatal death in an inland region of the State of São Paulo. A case-control study was conducted using a case group of 162 child deaths that occurred in 2009 in the state's VI Regional Health Department - Bauru. The control group consisted of 324 children selected from the Live Births Information System database who shared the same birth date and city of residence. Univariate and hierarchical multiple logistic regression analyses were performed to identify the factors associated with neonatal death by calculating crude odds ratios adjusted for potential confounders and respective 95% confidence intervals. RESULTS:The likelihood of neonatal death was greater among women who had had a history of infant death (OR = 24.97, CI = 12.20 to 51.10) and who had had only up to three antenatal appointments (OR = 11.40, CI = 5, 92 to 21.93), and among infants born at less than 28 weeks of gestation (OR = 168.00, CI = 49.63 to 568.66). The influence of birth weight was also observed among newborns weighing under 1,500g. CONCLUSIONS:This study identified five independent risk factors for neonatal death, the most notable of which is maternal history of neonatal death, which has not been properly acknowledged as a risk factor by previous studies. :O objetivo deste artigo é identificar os fatores de risco de óbito neonatal em região do interior paulista. Estudo de casos e controles. O grupo casos foi constituído por 162 crianças/óbitos neonatais ocorridos em 2009 na região do Departamento Regional de Saúde VI- Bauru/SP. Compuseram o grupo controle 324 crianças selecionadas do Sistema de Informações de Nascidos Vivos dentre aquelas com o mesmo ano de nascimento e município de residência. Para identificar os fatores associados ao óbito neonatal, realizou-se análise de regressão logística univariada e múltipla hierarquizada, estimando-se as razões de odds (e respectivos intervalos de confiança de 95%) brutas e ajustadas para potenciais fatores de confusão. Apresentaram maior chance de óbito os neonatos cujas mães tinham história de óbito infantil, realizaram até três consultas pré-natais e idade gestacional inferior a 28 semanas. A influência do peso ao nascer foi observada apenas entre crianças com peso inferior a 1500g. Este estudo identificou, de maneira independente, cinco fatores de risco para o óbito neonatal, com destaque para a história materna de óbito infantil anterior, fator ainda não valorizado em estudos prévios.
