Crianças nascidas entre 34 semanas e 36 semanas e seis dias de idade gestacional, denominadas prematuros tardios, são, tradicionalmente, considerados como de risco e prognóstico muito semelhantes aos dos recém-nascidos a termo. Estudos mais recentes, porém, têm mostrado que tanto prematuros tardios, quanto aqueles nascidos entre 37 e 38 semanas, apresentam resultados neonatais e no primeiro ano de vida, significativamente piores que os dos recém-nascidos a partir de 39 semanas. OBJETIVOS: revisar a literatura sobre o tema, analisar a prevalência de nascimento de prematuros tardios no tempo e comparar a frequência de mortes e complicações neonatais nos prematuros tardios e nos nascidos entre 37 e 38 semanas, com as mortes e complicações neonatais dos recém-nascidos a partir de 39 semanas. MÉTODO: revisão de literatura englobando os bancos de dados Medline, Lilacs e Biblioteca Cochrane. Realizado estudo de coorte retrospectiva com os dados de recém-nascidos vivos atendidos no Centro de Atenção Integral à Saúde da Mulher (CAISM) da Universidade Estadual de Campinas (UNICAMP), de janeiro de 2004 a dezembro de 2010. Os dados foram extraídos a partir do arquivo eletrônico da instituição. Foram excluídos os casos sem informação sobre a idade gestacional, as malformações e doenças congênitas fetais e as gestações múltiplas. Além das mortes neonatais, foram estudadas as seguintes complicações: hemorragia do sistema nervoso central, convulsões, índice de Apgar menor que sete no primeiro e quinto minutos, pneumonia, atelectasia, displasia broncopulmonar, pneumotórax, laringite pós entubação, síndrome de aspiração de mecônio, hipotermia, hipocalcemia e icterícia. As variáveis de controle foram: idade materna, estado civil, tabagismo, realização de pré-natal, hipertensão arterial (pré eclampsia ou crônica), diabetes, infecção urinária, outras morbidades maternas, primiparidade, cinco ou mais partos anteriores, tipo de parto, crescimento fetal restrito e sexo do recém-nascido. Para análise estatística foi aplicado o teste de qui-quadrado e o teste exato de Fisher, quando indicado. Assumiu-se o valor de p menor que 0,05 como significâncias estatísticas. Foi utilizado odds ratio (OR) como medida de efeito e a regressão logística múltipla para a análise multivariada. RESULTADOS: Foram estudados 18.032 nascimentos únicos, sendo 1.653 prematuros tardios e 16.379 recém nascidos de termo. Houve mais mortes neonatais (OR ajustado = 5.30; IC 95%: 2,61?10,74) nos prematuros tardios em comparação com os recém-nascidos a termo (nascidos entre 37 e 42 semanas). Também houve mais mortes neonatais (OR ajustado = 2,44; IC 95% 1,05-5,63) nos recém-nascidos de termo precoce comparados aos de termo tardio. Houve associação significativa para todas as complicações estudadas com a prematuridade tardia, exceto para síndrome de aspiração de mecônio. Encontrou-se tendência significativa de aumento na proporção de prematuros tardios em relação ao total dos partos ao longo do período estudado. CONCLUSÃO: Conclui-se que tanto os prematuros tardios quanto os nascidos entre 37 e 38 semanas são uma população de maior risco se comparados aos recém-nascidos a partir de 39 semanas / Abstract: INTRODUCTION: Gestational age at birth is a major determinant of neonatal mortality and complications. The risk of death and complications in infants born at 34 to 36 weeks of pregnancy (named late preterm infants) has been traditionally considered to be very similar to that of term infants. Some recent studies, however, have shown that late preterm infants, as well as those born at 37 and 38 weeks, have significantly worse outcomes in the neonatal period and in the first year of life than those born at 39 weeks or later. OBJECTIVE: to conduct a literature review on this issue; assess the prevalence and any temporal trend in late preterm births in the period that was studied; to compare neonatal deaths and complications in late preterm infants versus term infants, and compare neonatal deaths in infants born at 37 and 38 weeks (early term) versus those born at 39 to 42 weeks (late term). METHODS: A retrospective cohort study of live births was carried out in the Women's Integrated Healthcare Center (CAISM), State University of Campinas (UNICAMP), from January 2004 to December 2010. Data were extracted from an electronic database containing all medical records of the institution. Excluded from the study were congenital diseases and malformations, multiple pregnancies and cases without data on gestational age. Outcomes studied were neonatal deaths, length of hospital stay and the following complications: central nervous system hemorrhage, convulsions, Apgar score lower than seven at the first and fifth minute, pneumonia, atelectasis, pneumothorax, bronchopulmonary dysplasia, pulmonary hypertension, postintubation laryngitis, meconium aspiration syndrome, hypothermia, hypocalcemia and jaundice. Control variables were: maternal age, marital status, smoking habit, and absence of prenatal care, maternal hypertensive disease, maternal diabetes, urinary tract infection, other maternal morbid condition, primiparity, five or more previous births, fetal growth restriction, fetal gender, labor induction and pre labor cesarean section. It was used the chi square test and Fischer's exact test when indicated. The odds ratio (OR) was used as a measure of effect and multiple logistic regression was used for multivariate analysis. A significant level of 5% was adopted. RESULTS: After exclusions, there were 18,032 single births (1,653 late preterm births and 16,379 term births). An adjusted OR of 5.30; 95% confidence interval of 2.61--- 10.74 was found for neonatal death in late preterm births compared to term births (at 37 to 42 weeks), and an adjusted OR of 2.44; 95 confidence interval of 1.05-5.63 for neonatal death in early term births compared to late term births. A significantly higher risk was found in late preterm infants compared to term infants for all complications studied, except for meconium aspiration syndrome. There was a significantly growing trend in the proportion of late preterm births at the institution in the period studied. CONCLUSION: It was concluded that late preterm infants are at higher risk of undesirable outcomes than term infants. Furthermore, early term infants have a higher risk of death compared to late term infants and these differences are clinically relevant / Doutorado / Saúde Materna e Perinatal / Doutor em Ciências da Saúde

As informações de mortalidade são úteis para avaliar a situação de saúde de uma população. Dados de mortalidade confiáveis produzidos por um sistema de informação de saúde nacional constituem uma ferramenta importante para o planejamento de saúde. Em muitos países, sobretudo em desenvolvimento, o sistema de informação de mortalidade continua precário. Apesar dos esforços feitos em Moçambique para melhoria das estatísticas de mortalidade, os desafios ainda prevalecem em termos de tecnologias de informação, capacidade técnica de recursos humanos e em termos de produção estatística. O SIS-ROH é um sistema eletrônico de registro de óbitos hospitalares de nível nacional, implementado em 2008 e tem uma cobertura de apenas 4% de todos os óbitos anuais do país. Apesar de ser um sistema de nível nacional, ele presentemente funciona em algumas Unidades Sanitárias (US), incluindo o Hospital Central da Beira (HCB). Dada a importância deste sistema para monitorar o padrão de mortalidade do HCB e, no geral, da cidade da Beira, este estudo avalia a qualidade do SIS-ROH do HCB. É um estudo descritivo sobre a completitude, cobertura, concordância e consistência dos dados do SIS-ROH. Foram analisados 3.009 óbitos de menores de 5 anos ocorridos entre 2010 e 2013 e regsitrados no SIS-ROH e uma amostra de 822 Certificados de Óbitos (COs) fetais e de menores de 5 anos do HCB. O SIS-ROH apresentou uma cobertura inferior a 50% calculados com os dados de mortalidade estimados pelo Inquérito Nacional de Causas de Morte (INCAM). Verificamos a utilização de dois modelos diferentes de CO (modelo antigo e atual) para o registro de óbitos referentes ao ano de 2013. Observou-se completitude excelente para a maioria das variáveis do SISROH. Das 25 variáveis analisadas dos COs observou-se a seguinte situação: 9 apresentaram completitude muito ruim, sendo elas relativas à identificação do falecido (tipo de óbito e idade), relativas ao bloco V em que dados da mãe devem ser obrigatoriamente preenchidos em caso de óbitos fetais e de menores de 1 ano (escolaridade, ocupação habitual, número de filhos tidos vivos e mortos, duração da gestação) e relativas às condições e às causas de óbito (autópsia e causa intermédiacódigo); 3 variáveis apresentaram completitude ruim relativas à identificação do falecido (NID) e relativas às condições e causas de morte (causa intermédia - descrição e causa básica - código); 9 apresentaram completitude regular relativas à identificação do falecido (data de nascimento e idade), relativas ao bloco V (idade da mãe, tipo de gravidez, tipo de parto, peso do feto/bebé ao nascer, morte do feto/bebé em relação ao parto) e relativas às condições e causa de óbito (causa direta- código, causa básica descrição); 2 apresentaram completitude bom relativas à identificação do falecido (sexo e raça/cor) e, por último, 2 apresentaram completitude excelente relativas ao local de ocorrência de óbito (data de internamento e data de óbito ou desaparecimento do cadáver). Algumas variáveis do SIS-ROH e dos COS apresentaram inconsistências. Observou-se falta de concordância para causa direta entre o SIS-ROH e os COs. Conclusão: Moçambique tem feito esforços para aprimorar as estatísticas de mortalidade, porém há lacunas na qualidade; a análise rotineria dos dados pode identificar essas lacunas e subsidiar seu aprimoramento. / The mortality information is useful to assess the health status of a population. Reliable mortality data produced by a national health information system is an important tool for health planning. In many countries, especially developing countries, the mortality information system is still precarious. Despite efforts in Mozambique to improve mortality statistics, challenges still prevail in terms of information technology, technical capacity and human resources and statistical production. The SIS-ROH is an electronic system of national-level hospital deaths registration, implemented in 2008 and has a coverage of only 4% of all annual deaths in the country. Despite being a national system, it currently works in some health units (US), including Beira Central Hospital (HCB). Given the importance of this system to monitor the mortality pattern of HCB and, in general, the city of Beira, this study evaluates the quality of SIS-ROH HCB. It is a descriptive study on the completeness, coverage, compliance and consistency of the SIS-ROH data and examined a sample of 822 HCB deaths Certificates (COs) of fetal and children under 5 years of age. We find the use of two different models of CO (former and current model) for the registration of deaths related to the year 2013. We observed excellent completeness for most SIS-ROH variables. Of the 25 variables of COs there was the following situation: 9 had very bad completeness, which were relating to the identification of the deceased (type of death and age) on the V block in the mother\'s data, where must be filled in case of stillbirths and children under 1 year of age (education, usual occupation, number of living children taken and killed, gestational age) and on the conditions and causes of death (autopsy and intermediate-code causes); 3 variables had bad completeness concerning the identification of the deceased (NID) and on the conditions and causes of death (intermediate cause - description and basic cause - code); 9 showed regular completeness concerning the identification of the deceased (date of birth and age) on the V block (mother\'s age, type of pregnancy, mode of delivery, weight of the fetus / baby birth, death of the fetus / baby compared to delivery) and on the conditions and causes of death (direct cause code, basic cause description); 2 showed good completeness concerning the identification of the deceased (sex and race / color) and, finally, 2 showed excellent completeness concerning the place of occurrence of death (date of admission and date of death or the disappearance corpse). The SIS-ROH had coverage below 50% calculated on mortality data estimated by the National Survey of Causes of Death (INCAM). Some SIS-ROH variables and COS showed inconsistencies. There was a lack of agreement to direct cause between SIS-ROH and COs.

Introdução: O presente estudo trata da evolução da mortalidade perinatal hospitalar do município de Fortaleza-Ceará em dois momentos: 1995 e 2005. O interesse para a realização desta pesquisa parte da relevância dos cuidados oferecidos à mulher grávida e ao recém nascidocomo importante indicador da saúde materno infantil.Objetivos: Avaliar a evolução dos indicadores de saúde perinatal referentes aos nascimentos hospitalares de Fortaleza, Ceará, ocorridos em 1995 e em 2005.Metodologia: Estudo epidemiológico, do tipo ecológico, que estuda a evolução da saúde perinatal em Fortaleza, de 1995 a 2005, a partir da análise dos dados de dois estudos de base hospitalar. Todos os nascimentos foram acompanhados desde o parto até a alta ou óbito em hospital.Fizeram parte da população, todos os nascimentos e respectivos óbitos perinatais ocorridos em hospitais/maternidades públicas e particulares, conveniados com o SUS, no município de Fortaleza, CE, em 1995 e em 2005, disponíveis em dois bancos de dados já existentes.Resultados: Os resultados evidenciaram que nos dez anos (1995-2005) houve melhoria nos indicadores de saúde perinatal em Fortaleza. Os coeficientes de mortalidade perinatal hospitalar, fetal e neonatal precoce tiveram redução de 29 por cento, 19,0 por cento e de 42 por cento respectivamente. Em crianças com baixo peso ao nascer,observou-se declínio na mortalidade perinatal, fetal e neonatal precoce em todas as categorias. Chama-se atenção para a redução do coeficiente de mortalidade perinatal no grupo de recém nascidos de muito baixo peso (< 1500g), que passou de 821,1/1000 NV em 1995 para 532,2/1000 NV em 2005, com um declínio de 35,2 por cento. Quanto ao coeficiente de mortalidade neonatal precoce, a redução foi de 53,8 por cento, passando de 703,0/1000 NV para 324,7/1000 NV. Foi possível evidenciar mudanças referentes à reorganização da atenção perinatal em Fortaleza, quando se detectou uma maior participação dos hospitais públicos, que realizou um maior número de partos nos dez anos em 121 por cento por cento. Em 1995 a proporção de partos foi de 32,4 por cento e em 2005 de 71,7 por cento. Quanto à idade materna, os coeficientes de mortalidade perinatal, fetal e neonatal precoce nos dez anos tiveram reduções, com ênfase entre os filhos de mães adolescentes (10 a 19 anos). Para este grupo, o coeficiente de mortalidade perinatal obteve declínio de 54,2 por cento o de mortalidade fetal de 16,2 por cento e o de mortalidade neonatal precoce de 36,8 por cento. Conclusões: A mudança nos indicadores da saúde perinatal no município de Fortaleza mostra que houve uma melhora da atenção ao longo dos dez anos, revelando um cenário favorável na atenção prestada à mulher grávida e ao recém nascido na capital. Contudo, sabe-se que aspectos relacionados com o processo de trabalho e a organização da rede, ainda permanecem em níveis inferiores em relação , quando compara-se com outras capitais brasileiras, sendo necessárias medidas governamentais para que estas lacunas sejam remediadas / Introduction: This study deals with the evolution of perinatal mortality hospital in Fortaleza, Ceara on two occasions: 1995 and 2005. The interest for this research part of the relevance of care offered to pregnant women and newborn care as an important indicator of maternal and infant health.Objectives: To evaluate perinatal health indicators relating to hospital births in Fortaleza, occurring in 1995 and 2005.Methodology: Epidemiological study of ecological type, which studies the evolution of perinatal health in Fortaleza, from 1995 to 2005, based on the analysis of data from two hospital-based studies. All births were followed from birth until discharge or death in hospital. The population was composed of all births and perinatal deaths occurred in their hospitals / public hospitals and private contracts with the SUS in the city of Fortaleza, in1995 and 2005, available in two databases that already exist.Results: The results showed that within ten years (1995-2005) found a reduction in perinatal health indicators in Fortaleza. The hospital perinatal mortality rates, fetal and early neonatal fell by 29 per cent, 19.0 per cent and 42 per cent respectively. As birth weight were obtained decline in perinatal mortality, fetal and early neonatal in all categories. Attention is drawn to the reduction of perinatal mortality rate in the group of infants with very low birthweight (<1500g), now 821.1 / NV in 1000 to 532.2 in 1995 / 1000 NV in 2005, with a declining 35.2 per cent. As for early neonatal mortality rate, the reduction was 53.8 per cent, from 703.0 / 324.7 for 1000 NV / NV 1000. The results showed changes related to the reorganization of perinatal care in Fortaleza, when it detected a greater involvement of public hospitals, which increased the number of births in the ten years 121 per cent per cent. In 1995 the proportion of births was 32.4 per cent and 71.7 per cent in 2005. As for maternal age, perinatal mortality rates, fetal and early neonatal ten years have had reductions, with emphasis among the children of teenage mothers (10-19 years). For this group, the perinatal mortality rate decline of 84.7 per cent was obtained, the fetal mortality of 46.8 per cent and early neonatal mortality rate of 88.7 per cent.Conclusions: The change in perinatal health indicators in Fortaleza shows that there was an improvement of attention over the ten years, revealing a favorable outlook on care provided to pregnant women and newborn in capital.Contudo, it is known that aspects related to the work process and organization of the network, are still inconsistent when it is compared with other Brazilian cities, requiring government measures to these deficiencies are remedied

The purpose of this study was to investigate the determinants of high neonatal mortality rates in Migori County, Kenya. The neonatal mortality cases were utilised as the target population to the study. A quantitative, descriptive, cross-sectional, non-experimental research design was used. A systematic sampling technique was employed to draw a sample of 201 archived neonatal cases out of 420 neonatal mortality medical records, which constituted the study population. Data were collected by means of a developed questionnaire. The Statistical Package for Social Sciences (SPSS) Version 21 was used to analyse data. The main findings revealed the leading determinants of neonatal mortality were early neonatal period, prematurity, poor 1st Apgar score, low birth weight and neonates with intrapartum complications. Obstetrical haemorrhage and HIV were the main maternal complications associated to neonatal mortalities, while the leading direct causes of death in this study were birth asphyxia and sepsis. Other determinants were gender, rural residence, lowly educated and informally employed mothers. To reduce mortalities, a multifaceted approach is needed to establish quality improvement in neonatal intensive care, reduce preterm birth incidences, and empower mothers socio-economically. / Health Studies / M.A. (Nursing Science)

[Truncated abstract] The aims of the study were twofold; firstly, to describe the inequality in infant mortality in Indonesia namely, to look at the extent and magnitude of the problem in terms of the estimated number of infant deaths, the differentials in infant mortality rates, the probability of infant deaths across provinces, urban and rural areas, and across regions of Indonesia. Secondly, to examine the effect of family welfare status and maternal educational levels on the probability of infant deaths. The study design was that of a population-based multistage stratified survey of the 1997 Indonesian Demographic and Health Survey. Results of the study were obtained from a sample of 28,810 reproductive women aged 15 to 49 years who belonged to 34,255 households. A binary outcome variable was selected, namely, whether or not each of the live born infant(s) from the interviewed women was alive or dead prior to reaching one year of age. Of interest were the variables related to socio-economic status, measured by Family Welfare Status Index and maternal educational levels. The following risk factors were also investigated: current contraceptive methods; birth intervals; maternal age at first birth; marital duration; infants’ size perceived by the mothers; infants’ birth weight; marital status; prenatal care by health personnel; antenatal TT immunization; place of delivery; and religion. Geographical strata (province) and residence (urban and rural areas) were also considered. Both descriptive and multivariate analyses were undertaken. Descriptive analysis was aimed at obtaining non-biased estimates of the infant mortality rates at the appropriate levels of aggregation. Multivariate analysis involved a logistic regression model using the Generalized Estimating Equations (GEE) model-fitting technique. The procedure, a multilog-cumlogit , uses the Taylor Series Linearization methods to compute modelbased variance, and which adjusts for the complex sampling design. Results of descriptive analysis indicate that, indeed, there are inequalities in infant mortality across administrative divisions of the country, represented by provinces and regions, as well as across residential areas, namely urban and rural areas. Also, the results suggested that there is socio-economic inequality in infant mortality, as indicated by a dose-response effect across strata of family welfare and maternal educational levels, both individually and interactively. These inequalities varied by residence (urban and rural), provinces and regions (Java Bali, Outer Java Bali I and Outer Java Bali II). Furthermore, the probability of infant mortality was significantly greater among highrisk mothers, characterized by a number of risk factors used in the study

Purpose of the study - Identify predictors of mortality and develop a related care plan for patients who are on antiretroviral therapy (ART) in Gondar, Ethiopia. Design - A quantitative, retrospective cohort study was conducted analysing medical records of HIV patients who presented to Gondar University Hospital (GUH), Gondar, and started ART between 1 January 2007 and 30 June 2010. Results - In defining the predictors of mortality, the findings in bivariate analysis revealed: female sex, CD4 cell count ≤ 50/μl, CD4 cell count 51-199/μl, a haemoglobin concentration ≤8g/dl, a history of oral candidiasis, tuberculosis and Cryptococcus meningitis were all statistically significant. A female sex, CD4 cell count ≤ 50/μl and CD4 cell count 51-199/μl maintain their significance level in the multivariate analysis. Conclusions - The study therefore recommends that clinicians and case managers be vigilant of these predictors of mortality while managing HIV patients who are on ART / Health Studies / M.A. (Public Health)

The main objective of the present diploma thesis is to evaluate the development and spatial differentiation of infant mortality of the Czech population. In the scope of the research, our intent is to focus on various factors that might influence infant mortality and the values of which are accessible in public databases. The first partial objective was to evaluate the development of infant mortality of the Czech population in the 20th century and at the beginning of the 21st century. The second partial objective was to delineate specifics of the development of infant mortality in connection with the development of related social and economic characteristics. The third partial objective was to analyse regional differences of infant mortality within the scope of the Czech Republic. Finally, the fourth partial objective was to provide the breakdown of infant mortality.In the framework of the thesis, the following hypotheses have been stipulated: H1: Infant mortality is steadily on the decrease, H2: In the Czech Republic, there exist regional differences in infant mortality, influenced by economic, social and environmental factors, H3: The structure of infant mortality gradually changes towards the shift of the highest level of infant mortality at the beginning of life.It was possible to confirm hypothesis H1, which was examined within a quantitative research, using the moving average method - base and chain indexes. Infant mortality has been on the decrease as early as since the beginning of the 20th century in the Czech territory. The reduction in infant mortality is affected by changes in prenatal and early neonatal mortality, which fact was contributed to by quality prenatal and neonatal diagnostics of endogen causes of mortality. Accordingly, the trend of reduction in infant mortality continues, specifically up to the value of 2.6 , which was, as the lowest value, recorded in the year 2012. Similarly, it was possible to confirm hypothesis H2, tested within a quantitative research, using factor and cluster analyses, which have showed differences in factors (stability of social relationships, education of women, quality of healthcare, economic activity of women and their marital status, nationality and unemployment of women) in the scope of individual districts. It was moreover possible to confirm hypothesis H3, evaluated within a quantitative research and processed by means of simple descriptive indicators and graphs. The proportion of neonatal mortality in infant mortality stands at the average value of 62% for the period of 12 years. In consequence, we may assume that the proportion of neonatal mortality (28 days after birth) in infant mortality will constantly have an above-the-average value in the future. Based on the breakdown of infant mortality, it has been ascertained that chiefly the highest values are reached by early neonatal mortality (0 - 6 days) and it has a decreasing trend for the period of 12 years, reaching the average value of 1.26. This finding also confirms hypothesis H3, for the reason that early neonatal mortality is the component of neonatal mortality that has held the above-the-average proportion of infant mortality.In conclusion, we have conducted a correlation analysis of infant mortality with factors generated by the factor analysis. This analysis confirmed unambiguously that infant mortality is affected chiefly by the stability of social relationships and education of women.The no less important conclusion of the present thesis is seen in the fact that in the future, the society and experts engaged in problems of infant mortality should be more interested in researching various factors that influence infant mortality from both the positive and negative aspects. Findings of this diploma thesis may serve in practice as a background for any demographic research concerned with infant mortality.

A taxa de mortalidade perinatal (TMP) é um dos importantes indicadores de saúde que refletem a qualidade da assistência prestada durante a gestação, o parto e ao recém nascido. A TMP possui dois componentes: a taxa e mortalidade fetal e a taxa de mortalidade infantil neonatal precoce. O objetivo do presente estudo foi analisar a mortalidade perinatal na região do Médio Paraíba, estado do Rio de Janeiro, Brasil no período de 2005 a 2009, segundo causa básica dos óbitos, componentes do período perinatal e critérios de evitabilidade. Foram utilizados os dados referentes aos óbitos fetais e infantis neonatais precoces e de nascidos vivos, registrados, respectivamente, nos Sistemas de Informações sobre Mortalidade (SIM) e Nascidos Vivos (SINASC). A TMP na região foi de 18,4 óbitos por mil nascimentos totais. As taxas de mortalidade fetal e infantil neonatal precoce no período alcançaram, espectivamente 10,7 óbitos por mil nascimentos totais e 7,7 óbitos por mil nascidos vivos. A TMP apresentou redução ao longo do quinquênio analisado associada à queda do componente neonatal precoce, mantendo-se estável o componente fetal. As principais causas básicas dos óbitos perinatais, segundo a lista de mortalidade CID BR, foram as afecções originadas no período perinatal (89%) e as malformações congênitas, deformidades e anomalias cromossômicas (10,5%). Utilizando os critérios de evitabilidade segundo Ortiz, para os óbitos infantis neonatais precoces foi observado que mais de 41% eram reduzíveis por diagnósticos e tratamento precoces. Ressalta-se a necessidade da implementação de ações de assistência à saúde da gestante e de cuidados com o recémnascido com vistas à redução da mortalidade perinatal na região do Médio Paraíba. / The perinatal mortality rate (PMR) is an important health indicator that reflects the quality of health care provided during pregnancy, childbirth and to the newborns. The PMR has two components: the fetal mortality rate and the early neonatal mortality rate. The objective of this study was to analyze the perinatal mortality in the Médio Paraíba region, Rio de Janeiro state, Brazil between 2005 and 2009, according to the underlying cause of deaths, components of the perinatal period and criteria of avoidability. Data regarding fetal and early neonatal deaths and live births was provided by the National Death (SIM) and Live Birth (SINASC) Information Systems, respectively. The PMR in the region was 18.4 deaths per thousand total births. Fetal and early neonatal mortality rates reached 10.7 deaths per thousand total births and 7.7 deaths per thousand live births, respectively. The PMR declined during the five year period, associated with the fall of its early neonatal component, remaining stable the fetal component. The main underlying causes of perinatal deaths, according to the ICD Mortality List for use in Brazil - ICD BR, were certain conditions originating in the perinatal period (89%) and congenital malformations, deformations and chromosomal abnormalities (10,5%). Using the criteria of avoidability according to Ortiz, for early neonatal infant deaths was observed that over 41% were avoidable through early diagnosis and treatment . Efforts aimed at improving health care during pregnancy and childbirth are needed in order to reduce perinatal mortality levels in the Médio Paraíba region.
