Avaliação de preditores do óbito neonatal em uma série histórica de nascidos vivos no Nordeste brasileiro An evaluation of the predictors of neonatal death in a time series of live births in the Northeast Region of Brazil
Abstract
OBJETIVOS: avaliar tendência dos preditores do óbito neonatal entre os nascidos vivos e qualidade do preenchimento do Sistema de Informações para Nascidos Vivos (Sinasc) institucional. MÉTODOS: série histórica do Sinasc do Instituto de Medicina Integral Prof. Fernando Figueira (1995-2006) em Recife, Pernambuco, Brasil. Foram avaliadas: completitude de preenchimento das variáveis e tendência dos indicadores de risco para mortalidade infantil (baixo peso ao nascer; anóxia; prematuridade; cesariana; ausência de pré-natal; mãe adolescente; analfabetismo e nenhum filho nascido vivo e morto). Significância estatística para teste t de Student foi de 5% em um modelo de regressão linear. RESULTADOS: 58.689 nascidos vivos com contínuo incremento a partir de 2002; baixo peso ao nascer, 22,8%; Apgar OBJECTVES: to evaluate predictors of neonatal death among live births and the quality of use of the institutional Live Birth Information System register (Sinasc). METHODS: a time serie based on data from the Sinasc of the Instituto de Medicina Integral Prof. Fernando Figueira (1995-2006) in the city Recife, Pernambuco, Brazil. The following were evaluated: the completeness of the forms and the tendency regarding risk factors for infant mortality (low birth weight; anoxia; premature birth; caesarian birth; lack of prenatal care; adolescent pregnancy; illiteracy; and having had no live or still born child). Statistical significance was tested using Student's t test with p<0.05 in a linear regression model. RESULTS: 58,689 live births occurred with a continued rise from 2002 onwards; low birth weight, 22.8%; Apgar <7 1º minute 15.3%; premature 22.4%; Caesarian birth 38,2%; adolescent mothers 27.2%; illiteracy 2.7% and 89% with no live or still born child. One percent of variables were not recorded. The following variables increased (p<0.05): Apgar in the 1st minute, low birth weight, premature birth and caesarian birth; and the following decreased (p<0,05): no pre-natal consultation, adolescent pregnancy, illiteracy and having had no live or still born child. CONCLUSIONS: increasing percentages for the predictors of infant mortality suggest problems with the quality of pre-natal care. With only 1% of information overlooked, the quality of the keeping of SINASC records at the institution was found to be excellent. Routine evaluation of births allows for agility of information and appropriate intervention to prevent neonatal mortality at local level.
