Assessing the risks for stillbirth in São Paulo, Brazil: protocol for a multidisciplinary case-control study - FetRisks.

Stillbirth is a fundamental component of childhood mortality, but its causes are still insufficiently understood. This study aims to explore stillbirth risk factors by using a multidisciplinary approach to stimulate public policies and protocols to prevent stillbirth, improve maternal care and support bereaved families. METHODS AND ANALYSIS: In this case-control study with stillbirths and live births in 14 public hospitals in São Paulo, mothers are interviewed at hospitals after delivery, and hospital records and prenatal care registries are reviewed. Maternal and umbilical cord blood samples and placentas are collected to analyse angiogenesis and infection biomarkers, and the placenta's anatomopathological exam. Air pollutant exposure is estimated through the participant's residence and work addresses. Traditional and non-invasive autopsies by image-guided histopathology are conducted in a subset of stillbirths. Subsample mothers of cases are interviewed at home 2 months after delivery on how they were dealing with grief. Information contained in the official prenatal care registries of cases and controls is being compiled. Hospital managers are interviewed about the care offered to stillbirth mothers. Data analysis will identify the main risk factors for stillbirth, investigate their interrelations, and evaluate health services care and support for bereaved families. We hope this project will contribute to the understanding of stillbirth's risk factors and related health services in Brazil, providing new knowledge about this central public health problem, contributing to the improvement of public policies and prenatal and puerperal care, helping to prevent stillbirths and improve the healthcare and support for bereaved families. ETHICS AND DISSEMINATION: This study protocol was approved by the Ethics Committee of the Municipal Health Secretary (process no 16509319.0.3012.5551) and of the Hospital das Clínicas, Faculdade de Medicina, Universidade de São Paulo (process no 16509319.0.0000.0068). Results will be communicated to the study participants, policy-makers and the scientific community.

Prevalence and risk of stillbirth according to biologic vulnerability phenotypes in the municipality of São Paulo, Brazil: A population-based cohort study.

OBJECTIVE: To estimate the prevalence and risk of stillbirths by biologic vulnerability phenotypes in a cohort of pregnant women in the municipality of São Paulo, Brazil, 2017-2019. METHODS: Retrospective population-based cohort study. Fetuses were assessed as small for gestational age (SGA), large for gestational age (LGA), adequate for gestational age (AGA), preterm (PT) as less than 37 weeks of gestation, non-PT (NPT) as 37 weeks of gestation or more, low birth weight (LBW) as less than 2500 g, and non-LBW (NLBW) as 2500 g or more. Relative risks (RR) with robust variance were estimated using Poisson regression. RESULTS: In all 442 782 pregnancies, including 2321 (0.5%) stillbirths, were included. About 85% (n = 1983) of stillbirths had at least one characteristic of vulnerability, compared with 21% (n = 92524) of live births. Fetuses with all three markers of vulnerability had the highest adjusted RR of stillbirth-SGA + LBW + PT (RR 155.00; 95% confidence interval [CI] 136.29-176.30) and LGA + LBW + PT (RR 262.04; 95% CI 206.10-333.16) when compared with AGA + NLBW + NPT. CONCLUSION: Our findings show that the simultaneous presence of prematurity, low birth weight, and abnormal intrauterine growth presented a higher risk of stillbirths. To accelerate progress towards reducing preventable stillbirths, one must identify the circumstances of greatest biologic vulnerability.

Is parenthood associated with self-rated health among women in Brazil?

BACKGROUND: Previous studies conducted in Europe and North America addressing the relationship between self-rated health and parenthood offer inconsistent results, with effects ranging from nonsignificant to significant and in opposite directions. The aim of the present study was to explore the relationship between parenthood and self-rated health (SRH) among women in Brazil (a country with strong inequalities) considering the time interval from the last delivery in the analyses, as proposed in previous studies set in Sweden. METHODS: The study used data from cross-sectional National Health Surveys in Brazil conducted from 2013 to 2014 and 2019 to 2020 with selected groups of 20,046 and 25,100 women for whom complete data were available on the variables of interest. The primary outcome was self-rated health measured on a five-point scale. Partial proportional odds models were employed. RESULTS: Compared to women that were not a parent, primiparous women whose delivery was within less than one year had a lower likelihood of worse SRH (OR (95% CI): 0.58-0.84 in 2013, and 0.64-0.94 in 2019), whereas multiparous women whose last delivery was more than one year earlier had greater likelihood of worse SRH (OR (95% CI): 1.08-1.27 in 2013, and 1.21-1.39 in 2019). CONCLUSIONS: An association was found between parenthood and SRH among Brazilian women. Considering the epidemiological relevance of SRH, different aspects of parenthood concerning parity and time since the last delivery should be considered in further analyses.

Risk factors for perinatal death in high-risk pregnant women at a tertiary hospital in Curitiba-PR, Brazil: a case-control study. / Fatores de risco para óbito perinatal em gestantes de alto risco de um hospital terciário de Curitiba-PR, Brasil: estudo caso-controle.

A case-control study was carried out to estimate risk factors for perinatal mortality in a referral hospital for high-risk pregnancies in Curitiba-PR. Sociodemographic, maternal, pregnancy and concept characteristics data were obtained from the hospital records of 316 cases and 316 controls from 2013 to 2017. A hierarchical multiple logistic regression analysis was performed, remaining in the final model variables with p < 0.05. The results show an increased risk of perinatal death in mothers with blood type B (OR = 2.82; 95%CI: 1.07-7.43), who did not undergo prenatal care (OR = 30.78; 95%CI: 4.23-224.29), fetuses with congenital malformations (OR = 63.90; 95%CI: 27.32-149.48), born under 28 (OR = 24.21; 95%CI: 1, 10-531.81) and between 28-31 weeks of gestation (OR = 6.03; 95%CI: 1.34-27.17) and birth weight below 1,000g (OR = 51.94; 95%CI: 4.31-626.46), between 1,000-1,499g (OR = 11.17; 95%CI: 2.29-54.41) and between 1,500-2,499g (OR = 2.75; 25-6.06). Concepts of pregnancies with premature outcome, low birth weight and the presence of congenital malformations are the main risk factors for perinatal death. On the other hand, adequate prenatal care is an important protective factor.

Estudo caso-controle com o objetivo de estimar os fatores de risco da mortalidade perinatal em um hospital de referência para gestações de alto risco em Curitiba-PR. Os dados de características sociodemográficas, maternas, da gestação e do concepto foram obtidos dos prontuários hospitalares de 316 casos e 316 controles do período de 2013 a 2017. Foi realizada análise de regressão logística múltipla hierarquizada, permanecendo no modelo final variáveis com p < 0,05. Os resultados mostram aumento do risco de óbito perinatal em mães com tipo sanguíneo B (OR = 2,82; IC95%: 1,07-7,43), que não realizaram pré-natal (OR = 30,78; IC95%: 4,23-224,29), conceptos com malformações congênitas (OR = 63,90; IC95%: 27,32-149,48), nascidos com menos de 28 (OR = 24,21; IC95%: 1,10-531,81) e entre 28-31 semanas de gestação (OR = 6,03; IC95%: 1,34-27,17) e peso ao nascer abaixo de 1.000g (OR = 51,94; IC95%: 4,31-626,46), entre 1.000-1.499g (OR = 11,17; IC95%: 2,29-54,41) e entre 1.500-2.499g (OR = 2,75; IC95%: 1,25-6,06). Conceptos de gestações com desfecho prematuro, baixo peso ao nascer e presença de malformações congênitas são os principais fatores de risco para o óbito perinatal. Em contrapartida, a assistência pré-natal adequada é importante fator de proteção.

Mortality of Bolivian immigrants in São Paulo, Brazil: analysis of avoidable causes. / Mortalidade de imigrantes bolivianos em São Paulo, Brasil: análise de causas evitáveis.

The objective was to analyze the mortality of Bolivian immigrants compared to the Brazilian population, living in the city of São Paulo, with an emphasis on the analysis of avoidable deaths. Descriptive study of deaths in the city of São Paulo, between 2007 and 2018, registered in the Mortality Information System. Deaths of people aged 5 to 74 years were analyzed, according to "Brazilian List of Causes of Preventable Deaths", according to groups and sex; Pearson's chi-square test was used to compare nationalities. The temporal trend of avoidable deaths was evaluated by Prais-Winsten regression. There were 1.123 Bolivians deaths and 883.116 among Brazilians, with a predominance of male deaths and the Bolivians died on average 13.6 years younger. The proportion of deaths from preventable causes was similar between Bolivians (71.0%) and Brazilians (72.8%) and the trend did not show significant proportional annual variation for both nationalities. There is a higher frequency, among Bolivians, of external causes (27.6%) and of causes reducible by actions to health promotion, prevention, control, and care for infectious diseases (20.8%) than to Brazilians. Conclusion: Bolivians died younger and showed no reduction in the proportion of potentially avoidable causes, which may indicate unequal access to health services.

Live births of immigrant mothers in Brazil: A population-based study.

Introduction: Migration has become a major challenge for many countries, and women constitute half of the migrants in the world. Few studies have been conducted on migrant mothers in Brazil. We aim to identify differences in the pregnancies, childbirths, and live birth (LB) indicators of immigrant women, compared with those of Brazilian women living in the municipality of São Paulo (MSP), Brazil. Methods: The LB characteristics of immigrant mothers from Bolivia (15,886), China (3861), Paraguay (1370), and Peru (1039) were compared with those of Brazilian mothers (967,921) living in the MSP between 2012 and 2017. Pearson's chi-square test was used to compare proportions with a significance level of 5%. Results: Teenage pregnancy and low education were more frequent among Bolivian (13.1 and 31.7%, respectively) and Paraguayan mothers (13.1 and 36.2%). Bolivian women exhibited a high percentage of late-onset prenatal care (8.7%), few prenatal visits (14.3%), vaginal birth (77.0%), home delivery (1.6%), and postterm (3.6%). Bolivian (13.6%), Peruvian (10.6%), and Paraguayan (7.9%) women exhibited a higher prevalence of macrosomia than Chinese (4.3%) and Brazilian (4.0%) women. There was a high prevalence of preterm and low birth weights among Paraguayan (12.5 and 7.7%, respectively) and Brazilian mothers (11.0 and 9.7%) and a high rate of cesarean sections among Chinese (42.1%) and Brazilian (53.5%). Conclusion: Differences were observed in the sociodemographic profiles for the pregnancies, childbirths, and LBs of immigrant mothers, in view of their increase and diversity in the MSP. There was greater vulnerability among immigrant mothers, compared with Brazilian mothers, particularly regarding access to prenatal care.

Spatiotemporal dynamics of syphilis in pregnant women and congenital syphilis in the state of São Paulo, Brazil.

We aimed to estimate the occurrence of syphilis in pregnant women (SPW) and congenital syphilis (CS) in the municipalities of the state of São Paulo (SP) and evaluate their relationship with socioeconomic, demographic, and health care variables. We developed an ecological study based on secondary data of SPW and CS with spatiotemporal components from 645 municipalities in SP including data from 2007 to 2018. We modeled the data in a Bayesian context, considered spatial and temporal random effects, and used binomial negative probability distributions. We found a continuous increase in the relative temporal risk of SPW, from 2007 to 2018, and CS, from 2007 to 2017, when their incidences increased by 8.6 and 6.6 times, respectively. This increase occurred en bloc in practically all municipalities of SP. The increase in SPW was associated with teenage pregnancy, municipalities with a large number of inhabitants, and acquired immunodeficiency syndrome (AIDS) incidence. The increase in CS was associated with municipalities with a large number of inhabitants, incomplete antenatal care, and AIDS incidence. Although actions to control these diseases are required in all municipalities of SP, the identification of high-risk areas points to priority regions for development.

Intra-urban differentials of fetal mortality in clusters of social vulnerability in São Paulo Municipality, Brazil.

This study aimed to analyze the distribution of stillbirths by birth weight, type of death, the trend of Stillbirth Rate (SBR), and avoidable causes of death, according to social vulnerability clusters in São Paulo Municipality, 2007-2017. Social vulnerability clusters were created with the k-means method. The Prais-Winsten generalized linear regression was used in the trend of SBR by < 2500 g, ≥ 2500 g, and total deaths analysis. The Brazilian list of avoidable causes of death was adapted for stillbirths. There was a predominance of antepartum stillbirths (70%). There was an increase in SBR with the growth of social vulnerability from the center to the outskirts of the city. The cluster with the highest vulnerability presented SBR 69% higher than the cluster with the lowest vulnerability. SBR ≥ 2500 g was decreasing in the clusters with the high vulnerability. There was an increase in SBR of avoidable causes of death of the cluster from the lowest to the highest vulnerability. Ill-defined causes of death accounted for 75% of deaths in the highest vulnerability area. Rates of fetal mortality and avoidable causes of death increased with social vulnerability. The trend of reduction of SBR ≥ 2500 g may suggest improvement in prenatal care in areas of higher vulnerability.

Use of linkage to analyze completeness and concordance of deaths from congenital syphilis in the Metropolitan Region of São Paulo, Brazil, 2010-2017: a descriptive study. / Uso de linkage para análise de completude e concordância de óbitos por sífilis congênita na Região Metropolitana de São Paulo, 2010-2017: estudo descritivo.

OBJECTIVE: To evaluate the completeness and concordance of infant deaths from congenital syphilis in the Metropolitan Region of Sao Paulo, Brazil, between 2010 and 2017. METHODS: This was a descriptive study based on linkage between the Mortality Information System (SIM) and the Live Birth Information System (SINASC). Deaths with mention of congenital syphilis in multiple causes of death were analyzed. The completeness of 11 SIM variables was analyzed and SINASC was adopted as the reference. The Kappa statistic was used to analyze concordance. RESULTS: There were 134 recorded congenital syphilis deaths, 132 of which were linked. 67 had congenital syphilis as the underlying cause, while 65 involved multiple causes of death, indicating underestimated congenital syphilis mortality. After linkage, the number of variables with excellent completeness increased from two to ten. CONCLUSION: Linking SIM with SINASC data improved completeness. The magnitude of congenital syphilis mortality was found to be underestimated, and the use of multiple causes improved its measurement.

Repeated cesarean section and vaginal delivery after cesarean section in São Paulo State in 2012 / Repetição de cesárea e parto vaginal após cesárea, no Estado de São Paulo, em 2012

Abstract Objectives: describe mothers, pregnancies and newborns' characteristics according to the type of childbirth history and to analyze repeated cesarean section (RCS) and vaginal delivery after cesarean section (VBACS), in São Paulo State in 2012. Methods: data are from the Sistema de Informações sobre Nascidos Vivos (Live Birth Information Systems). To find the RCS's group, the current type of childbirth equal to cesarean section was selected and from these all the previous cesareans. To identify the VBACS's group all live birth with current vaginal delivery were selected and from these all previous cesareans. Mothers with a history of RCS and VBACS were analyzed according to the characteristics of the pregnancy, newborn and the childbirth hospital. Results: 273,329 mothers of live birth with at least one previous child were studied. 43% of these were born of RCS and 7.4% of VBACS. Mothers who underwent RCS are older and higher educated and their newborns presented a lower incidence of low birth weight. Early term was the most frequent rating for gestational age born of RCS. Live births were of VBACS and had greater proportions of late term. The RCS was more common in hospitals not affiliated with the Sistema Único de Saúde (SUS) (Public Health System) (44.1%). Conclusion: the high RCS's rates, especially in the private sector, highlight the necessity of improvements in childbirth care model in São Paulo.

Resumo Objetivos: descrever características das mães, da gestação e do recém-nascido, segundo histórico de tipo de parto, analisando repetição de cesárea (RC) e parto vaginal após cesárea (PVAC), no Estado de São Paulo, em 2012. Métodos: os dados são provenientes do Sistema de Informações sobre Nascidos Vivos. Para encontrar o conjunto RC, selecionou-se o tipo de parto atual igual a cesárea e destes buscou-se todos com cesárea anterior. Para identificar o grupo PVAC, selecionou-se os recém-nascido com parto atual vaginal e destes buscou-se todos com cesárea anterior. Foram analisadas mães com história de RC e PVAC, segundo características da gestação, do recémnascido e hospital do parto. Resultados: estudou-se 273.329 nascidos vivos de mães com pelo menos um filho anterior. Destes, 43% nasceram por RC e 7,4% por PVAC. As mães que realizaram RC são mais velhas e mais escolarizadas, seus recém-nascidos apresentaram menor proporção de baixo peso ao nascer. Termo precoce foi a mais frequente idade gestacional dos que nasceram por RC. Os recém-nascidos por PVAC apresentaram maiores proporções de termo tardio. RC foi mais frequente nos hospitais sem vínculo com o Sistema Único de Saúde (44,1%). Conclusão: as altas taxas de RC, principalmente no setor privado, evidenciam necessidade de melhoras no modelo de atenção ao parto em São Paulo.

[Contributions by the investigation of fetal deaths for improving the definition of underlying cause of death in the city of São Paulo, Brazil]. / Contribuições da investigação dos óbitos fetais para melhoria da definição da causa básica do óbito no Município de São Paulo, Brasil.

This study aimed to analyze the time trend in stillbirth rate (SBR) and the contribution by investigation to improving the definition of underlying cause of stillbirth in the city of São Paulo, Brazil, according to the place where the death certificate was issued. An ecological approach was used to analyze the trend in SBR by weight stratum (< 2,500g and ≥ 2,500g) and total deaths in the city in 2007-2017. Prais-Winsten generalized linear regression was used. The study of cases analyzed the underlying causes of stillbirth from 2012 to 2014, before and after the investigation, time of conclusion of the investigation, and redefinition of the underlying cause of stillbirths by type of issuer. In deaths with < 2,500g, there was an upward trend in SBR of 1.5% per year and a reduction (-1.3% per year) in stillbirths ≥ 2,500g. Total deaths presented a stable trend. In 2012-2014, 90% of deaths with ≥ 2,500g were investigated. After investigation, the underlying cause of death was redefined in 15% of the deaths, and not otherwise specified stillbirth (P95) represented 25% of the causes of death. The highest proportion of changes in the underlying cause of death occurred in deaths for which the death certificate was issued by the death certification review service (17%), while in health services the proportion was 10.6%. In conclusion, the SBR in deaths with ≥ 2,500g showed a downward trend. There was a significant redefinition of underlying causes, especially in those attested by the death certification review service. However, the redefinition was insufficient to expand the proportion of causes of death that would allow a better understanding of the mortality conditions.

O objetivo desta pesquisa foi analisar a evolução temporal da taxa de mortalidade fetal (TMF) e a contribuição da investigação para a melhoria da definição da causa básica do óbito fetal no Município de São Paulo, Brasil, segundo local de emissão da declaração de óbito. Na abordagem ecológica, analisou-se a tendência da TMF por estrato de peso (< 2.500g e ≥ 2.500g) e óbitos totais no Município de São Paulo entre 2007-2017. Utilizou-se a regressão linear generalizada de Prais-Winsten. No estudo de casos, foram analisadas as causas básicas de óbito fetal de 2012 a 2014, antes e após a investigação, o tempo de conclusão da investigação e a redefinição da causa básica por tipo de atestante. Houve tendência de aumento (1,5% ao ano) da TMF dos óbitos com < 2.500g e de redução (-1,3% ao ano) naqueles com ≥ 2.500g. Os óbitos totais apresentaram tendência estacionária. Entre 2012-2014, cerca de 90% dos óbitos com ≥ 2.500g foram investigados. Após a investigação, houve redefinição da causa básica de morte em 15% dos casos, e a morte fetal não especificada (P95) representou 25% das causas de óbito. A proporção mais elevada de alteração da causa de morte ocorreu nos casos cuja Declaração de Óbito foi emitida pelos serviços de verificação de óbito (17%), ao passo que nos serviços de saúde foi de 10,6%. Concluiu-se que a TMF dos óbitos com ≥ 2.500g apresentou tendência de redução. Houve redefinição significativa das causas básicas, sobretudo naquelas atestadas pelo serviços de verificação de óbito. Entretanto, foi insuficiente para ampliar a proporção de causas de morte que permitissem maior compreensão das condições de mortalidade.

El objetivo de esta investigación fue analizar la evolución temporal de la tasa de mortalidad fetal (TMF) y la contribución de su investigación para la mejora de la definición de la causa básica del óbito fetal en el municipio de São Paulo, Brasil, según el lugar de emisión de la declaración de defunción. Desde una perspectiva ecológica, se analizó la tendencia de la TMF por estrato de peso (< 2.500g y ≥ 2.500g) y fallecimientos totales en el municipio de São Paulo entre 2007-2017. Se utilizó la regresión lineal generalizada de Prais-Winsten. En el estudio de casos se analizaron las causas básicas de óbito fetal de 2012 a 2014, antes y después de la investigación, el tiempo de conclusión de la investigación y la redefinición de la causa básica de los óbitos fetales por tipo de certificado. En las defunciones con < 2.500g, hubo una tendencia de aumento de la TMF de 1,5% al año y de reducción (-1,3% al año) en los óbitos fetales con ≥ 2.500g. Los óbitos totales presentaron tendencia estable. Entre 2012-2014, se investigaron cerca de un 90% de los óbitos con ≥ 2.500g. Tras la investigación, se produjo una redefinición de la causa básica de muerte en un 15% de los óbitos y la muerte fetal no especificada (P95) representó un 25% de las causas de óbito. La proporción más elevada de alteración de la causa de muerte se produjo en los óbitos, cuya declaración de fallecimiento se emitió por parte del servicio de verificación de óbito (17%), mientras que en los servicios de salud fue de un 10,6%. Se concluye que la TMF de los óbitos con ≥ 2.500g presentó una tendencia decreciente. Hubo una redefinición significativa de las causas básicas, sobre todo en aquellas certificadas por el servicio de verificación de óbito. No obstante, esta fue insuficiente para ampliar la proporción de causas de muerte que permitiesen una mayor comprensión de las condiciones de mortalidad.

Objetivo: Avaliar a completude e concordância dos óbitos infantis por sífilis congênita na Região Metropolitana de São Paulo, Brasil, no período 2010-2017. Métodos: Estudo descritivo, baseado na vinculação do Sistema de Informações sobre Mortalidade (SIM) com o Sistema de Informações sobre Nascidos Vivos (Sinasc). Foram considerados os óbitos com menção de sífilis congênita nas causas múltiplas de morte. Analisou-se a completude de 11 variáveis do SIM; adotou-se o Sinasc como referência. Para análise da concordância, utilizou-se o índice Kappa. Resultados: Registraram-se 134 óbitos por sífilis congênita; destes, 132 foram vinculados, sendo 67 como causa básica e 65 ao se considerar causas múltiplas de óbito, indicando subestimação da mortalidade. Após linkage, houve aumento de 2 para 10 variáveis com preenchimento excelente. Conclusão: A vinculação do SIM com dados do Sinasc melhorou sua completude. Identificou-se subestimação da magnitude da mortalidade por sífilis congênita, e o uso das causas múltiplas melhorou sua mensuração.

Resultados: Se registraron 134 muertes por SC, de las cuales 132 fueron vinculadas, siendo 67 como causa básica y 65 al considerar causas asociadas, lo que indica subestimación de la mortalidad. Después del linkage, hubo aumento de 2 para 10 variables con excelente completitud. Conclusión: La vinculación del SIM con el Sinasc mejoró la completitud. Se identificó subestimación de la magnitud de mortalidad por sífilis congénita y el uso de múltiples causas mejoró la medición.

Objective: To evaluate the completeness and concordance of infant deaths from congenital syphilis in the Metropolitan Region of Sao Paulo, Brazil, between 2010 and 2017. Methods: This was a descriptive study based on linkage between the Mortality Information System (SIM) and the Live Birth Information System (SINASC). Deaths with mention of congenital syphilis in multiple causes of death were analyzed. The completeness of 11 SIM variables was analyzed and SINASC was adopted as the reference. The Kappa statistic was used to analyze concordance. Results: There were 134 recorded congenital syphilis deaths, 132 of which were linked. 67 had congenital syphilis as the underlying cause, while 65 involved multiple causes of death, indicating underestimated congenital syphilis mortality. After linkage, the number of variables with excellent completeness increased from two to ten. Conclusion: Linking SIM with SINASC data improved completeness. The magnitude of congenital syphilis mortality was found to be underestimated, and the use of multiple causes improved its measurement.

This study aimed to analyze the time trend in stillbirth rate (SBR) and the contribution by investigation to improving the definition of underlying cause of stillbirth in the city of São Paulo, Brazil, according to the place where the death certificate was issued. An ecological approach was used to analyze the trend in SBR by weight stratum (< 2,500g and ≥ 2,500g) and total deaths in the city in 2007-2017. Prais-Winsten generalized linear regression was used. The study of cases analyzed the underlying causes of stillbirth from 2012 to 2014, before and after the investigation, time of conclusion of the investigation, and redefinition of the underlying cause of stillbirths by type of issuer. In deaths with < 2,500g, there was an upward trend in SBR of 1.5% per year and a reduction (-1.3% per year) in stillbirths ≥ 2,500g. Total deaths presented a stable trend. In 2012-2014, 90% of deaths with ≥ 2,500g were investigated. After investigation, the underlying cause of death was redefined in 15% of the deaths, and not otherwise specified stillbirth (P95) represented 25% of the causes of death. The highest proportion of changes in the underlying cause of death occurred in deaths for which the death certificate was issued by the death certification review service (17%), while in health services the proportion was 10.6%. In conclusion, the SBR in deaths with ≥ 2,500g showed a downward trend. There was a significant redefinition of underlying causes, especially in those attested by the death certification review service. However, the redefinition was insufficient to expand the proportion of causes of death that would allow a better understanding of the mortality conditions.

Factors associated with hospitalization and neonatal mortality in a cohort of newborns from the Unified Health System in São Paulo. / Fatores associados à internação e à mortalidade neonatal em uma coorte de recém-nascidos do Sistema Único de Saúde, no município de São Paulo.

INTRODUCTION: Newborn care is an important factor associated with hospitalization and neonatal mortality. OBJECTIVE: To analyze factors associated with hospitalization and neonatal mortality of newborns (NBs) admitted to the Unified Health System (SUS), São Paulo, 2012. METHODS: A cohort of NBs from the SUS was obtained by linking data: SUS Hospital Information System, Live Birth Information System, Mortality Information System and National Health Facility Registry. Poisson and Cox regression were performed. RESULTS: 16.5% (9,127) of the NBs were hospitalized, 4.7% (2,613) were admitted to a Neonatal Intensive Care Unit (NICU) and 11.8% (6,514) to a Neonatal Intermediate Care Unit (NIMCU). Maternal age ≥ 35 years (RR = 1.1, IC95% 1.1 - 1.2), inadequate prenatal care (RR = 1.2, IC95% 1.1 - 1.3), hospitalization for obstetric complications (RR = 1.1, IC95% 1.1 - 1.2), prematurity (≤ 32 weeks: RR = 1.6, IC95% 1.5 - 1.8; 32 to 36 weeks: RR = 1.7, IC95% 1.6 - 1,7), low weight (< 1,500 g: RR = 2.4, IC95% 2.1 - 2.6; 1,500 to 2,499 g: RR = 2.6, IC95% 2.5 - 2.7), APGAR 5º < 7 (RR = 1.9, IC95% 1.7 - 2.0), Cesarean section (RR = 1.1, IC95% 1.1 - 1.2) and Congenital Malformation (RR = 1.4, IC95% 1.3 - 1,5) were associated with the hospitalization of newborns. Neonatal mortality was associated with infants under 1,500 g (RR = 9.1, IC95% 6.3 - 13.1), very premature (RR = 2.6, IC95% 1.9 - 3.5), low APGAR (RR = 5.5, IC95% 4.6 - 6.7). CONCLUSION: Inadequate prenatal care, prematurity and low weight were risk factors for hospitalization and neonatal mortality.

[Markers of inequality in self-rated health in Brazilian adults according to sex]. / Marcadores de desigualdade na autoavaliação da saúde de adultos no Brasil, segundo o sexo.

The aim of this study was to analyze self-rated health in Brazil's adult population according to markers of health inequality (color or race, region of residence, schooling, per capita household income, and social class), stratified by sex. We studied 59,758 individuals 18 years or older who participated in the 2013 National Health Survey, a population-based household survey. Data collection used face-to-face interviews and key physical measurements. Self-rated health was classified as positive, fair, or negative. Multinomial logistic regression was used to estimate crude and adjusted odds ratios (OR) and respective 95% confidence intervals (95%CI). Percentage agreement and kappa values were calculated to compare the results obtained by regression models and the expected values. Prevalence of positive self-rated health in the overall population was 66.2% (70% in men and 62.6% in women). In the adjusted analysis, the odds of worse self-rated health were significantly higher in individuals with lower per capita household income, less schooling, from the lowest social classes, residents of the North and Northeast regions, and those with brown and black color/race. Public policies for health promotion and recovery in these more vulnerable social groups can help reduce the persistent health inequalities in Brazil.

O objetivo deste estudo foi analisar a autoavaliação da saúde da população adulta brasileira, segundo os marcadores de desigualdade em saúde (cor ou raça, região de residência, escolaridade, renda domiciliar per capita e classe social), estratificada pelo sexo. Foram estudados 59.758 indivíduos com 18 anos ou mais de idade, que participaram da Pesquisa Nacional de Saúde de 2013, inquérito domiciliar de base populacional. A coleta de dados foi feita por entrevistas face a face e algumas medidas físicas. A autoavaliação da saúde foi analisada como positiva, regular e negativa. Usando-se a regressão logística multinomial, foram estimados odds ratio (OR) brutos e ajustados e os respectivos intervalos de 95% de confiança (IC95%). Foram calculados os percentuais de concordância e o valor de kappa para comparar os valores obtidos pelos modelos de regressão e os valores esperados. A prevalência da autoavaliação de saúde positiva na população total foi de 66,2%, sendo 70% nos homens e 62,6% nas mulheres. Na análise ajustada, as chances de avaliar pior sua saúde foram significativamente mais elevadas entre os indivíduos de menor renda domiciliar per capita, com pior nível de escolaridade, das classes sociais mais desfavorecidas, moradores das regiões Norte e Nordeste e que se autodeclararam pardos e pretos. Políticas públicas voltadas à promoção e à recuperação da saúde desses grupos sociais mais vulneráveis podem impactar na redução das iniquidades em saúde persistentes no Brasil.

El objetivo de este estudio fue analizar la autoevaluación de la salud de la población adulta brasileña, según los marcadores de desigualdad en salud (color o raza, región de residencia, escolaridad, renta domiciliaria per cápita y clase social), estratificada por sexo. Se estudiaron a 59.758 individuos, con 18 años o más de edad, que participaron en la Encuesta Nacional de Salud de 2013, una encuesta domiciliaria de base poblacional. La recogida de datos se realizó mediante entrevistas cara a cara y algunas mediciones físicas. La autoevaluación de salud se analizó como: positiva, regular y negativa. A través de una regresión logística multinomial, se estimaron odds ratio (OR) brutos y ajustados y los respectivos intervalos de 95% de confianza (IC95%). Se calcularon los porcentajes de concordancia y el valor de kappa para comparar valores obtenidos por modelos de regresión y valores esperados. La prevalencia de la autoevaluación de salud positiva en la población total fue de 66,2%, siendo 70% en los hombres, y 62,6% en las mujeres. En el análisis ajustado, las oportunidades de evaluar peor la salud fueron significativamente más elevadas entre los individuos de menor renta domiciliaria per cápita, con peor nivel de escolaridad, de las clases sociales más desfavorecidas, habitantes de las regiones Norte y Nordeste y que se autodeclararon mestizos/mulatos y negros. Políticas públicas dirigidas a la promoción y a la recuperación de la salud de esos grupos sociales más vulnerables pueden impactar en la reducción de las inequidades en salud persistentes en Brasil.
