RESUMO
BACKGROUND: The purpose of this study was to investigate the association between mean body mass index (BMI) and prevalence of obesity in adult populations living in Brazilian State capitals. METHODS: An ecological study was conducted, using data from the National Household Budget Survey conducted in July 2002 through June 2003, including a representative sample of 48.470 households. Pearson's correlation and linear regression coefficients were estimated in order to define the relationships of mean BMI and sex-specific, age standardized obesity prevalence (BMI ≥ 30.0 kg/m(2)) in adults aged 20 to 59 years. RESULTS: Stronger correlations between BMI and prevalence of obesity were observed in women (r = 0.9; p < 0.001) than in men (r = 0.6; p = 0.001) in all analyzes. A reduction of one unit in mean BMI predicted a decline in the prevalence of obesity of about 4.0% (95% CI: 1.7-6.3) in men, and 3.4% (95% CI: 2.6-4.3) in women. CONCLUSION: We found a correlation between BMI and prevalence of obesity, particularly among women, suggesting that population-based strategies would be effective to reduce the prevalence of obesity in adult populations living in Brazilian state capitals.

BACKGROUND: Smoking epidemic in Brazilian women has later onset, smaller magnitude, and slower decreasing trend, compared to men. Among pregnant women, smoking has an additional deleterious effect. The purpose of this study was to analyze smoking prevalence during pregnancy and associated factors, and to describe the frequency of smoking reduction and cessation in public maternities of Rio de Janeiro State, southeastern Brazil, in 2011. METHODS: A cross-sectional study was conducted in two maternities located at public hospitals in two cities of the Rio de Janeiro state, Niterói (maternity A) and of Rio de Janeiro (maternity B). Data were gathered by interviews 12 hours after the delivery, and analyses of prenatal cards and medical records. Smoking prevalence according to maternal characteristics, adequacy of prenatal care, and proportions of smoking reduction and cessation during pregnancy were calculated. Factors associated to smoking during pregnancy were estimated by logistic regression analysis. RESULTS: Smoking prevalence at maternity A (24.8%, 95% CI: 21.1-29.0) and maternity B (17.9%, 95% CI: 15.8-20.1) were high. Prevalence rates were greater in women aged 20-34 years, mainly without partner, multiparous and brown or black skin color. Low education (OR = 2.14, 95% CI 1.21, 3.79) and multiparity (OR = 3.48, 95% CI 1.78, 6.81), at maternity A; adolescence (OR = 0.44, 95% CI 0.26, 0.75), black skin color (OR = 1.71, 95% CI 1.06, 2.74), low education (OR = 1.61, 95% CI 1.08, 2.40), and multiparity (OR = 1.58, 95% CI 1.03, 2.44), at maternity B, were associated with smoking in multivariable analysis. Adequacy of prenatal care and smoking prevalence showed an inverse association. More than half of the smokers kept the smoking habits during pregnancy. Reduction occurred mainly between the 1(st) and 2(nd) trimesters of pregnancy. CONCLUSION: Smoking prevalence during pregnancy was higher for multiparous and less educated women. Population and individual strategies for smoking prevention and control must include actions specific for women, especially during the reproductive period.

Intrauterine growth restriction and prematurity determine low birth weight. The combination of the three conditions results in different neonatal phenotypes that interfere with child survival. Neonatal prevalence, survival and mortality were estimated according to neonatal phenotypes in the cohort of live births in 2021 in the state of Rio de Janeiro, Brazil. In this study, live births of multiple pregnancies, with congenital anomalies and inconsistencies in the information of weight and gestational age were excluded. The Intergrowth curve was used to classify weight adequacy. Mortality (< 24 hours, 1-6 and 7-27 days) and survival (Kaplan-Meier) were estimated. In total, 6.8%, 5.5%, and 9.5% of the 174,399 live births were low birth weight, small for gestational age (SGA), and premature, respectively. Considering low birth weight live births, 39.7% were SGA and 70% were premature. The neonatal phenotypes were heterogeneous according to maternal, delivery, pregnancy, and newborn characteristics. The mortality rate per 1,000 live births was high for low birth weight premature newborns, both SGA (78.1) and AGA (adequate for gestational age: 61.1), at all specific ages. Reductions in the survival rate were observed when comparing non-low birth weight and AGA term live births. The estimated prevalence values were lower than those of other studies, partly due to the exclusion criteria adopted. The neonatal phenotypes identified children who were more vulnerable and at higher risk of death. Prematurity contributed more to mortality than SGA, and its prevention is necessary to reduce neonatal mortality in the state of Rio de Janeiro.
A restrição do crescimento intrauterino e a prematuridade determinam o baixo peso ao nascer, e a combinação das três condições resulta em diferentes fenótipos neonatais que interferem na sobrevivência infantil. Foram estimadas a prevalência, a sobrevivência e a mortalidade neonatal, segundo os fenótipos neonatais, na coorte de nascidos vivos de 2021 no Rio de Janeiro, Brasil. Foram excluídos nascidos vivos de gravidez múltipla, com anomalia congênita, e com inconsistências nas informações de peso e idade gestacional. Foi utilizada a curva Intergrowth para classificar adequação do peso, e estimadas a mortalidade (< 24 horas, 1-6 e 7-27 dias) e sobrevida (Kaplan-Meier). Dos 174.399 nascidos vivos, 6,8%, 5,5% e 9,5% eram, respectivamente, baixo peso ao nascer, pequeno para idade gestacional (PIG) e prematuros. Entre nascidos vivos com baixo peso ao nascer, 39,7% eram PIG e 70%, prematuros. Os fenótipos neonatais foram heterogêneos segundo características maternas, do parto, da gestação e do recém-nascido. A taxa de mortalidade por 1.000 nascidos vivos foi elevada para neonatos de baixo peso ao nascer prematuros, tanto PIG (78,1) quanto AIG (adequado para idade gestacional: 61,1), em todas as idades específicas. Houve reduções significantes da sobrevida quando comparados aos nascidos vivos não baixo peso ao nascer, AIG termo. As prevalências estimadas mostraram menores valores que as de outros estudos, em parte pelos critérios de exclusão adotados. Os fenótipos neonatais identificaram crianças mais vulneráveis e com maior risco de morte. A prematuridade contribuiu mais para a mortalidade que a condição de PIG; sua prevenção é necessária para reduzir a mortalidade neonatal no Estado do Rio de Janeiro.

De los 174.399 nacidos vivos, 6,8%, 5,5% y 9,5% fueron, respectivamente, bajo peso al nacer, pequeños para la edad gestacional (PIG) y prematuros. Entre los bacidos vivos com bajo peso al nacer, el 39,7% eran PIG y el 70% prematuros. Los fenotipos neonatales fueron heterogéneos según las características maternas, del parto, del embarazo y del recién nacido. La tasa de mortalidad por 1.000 nacidos vivos fue alta para los neonatos bajo peso al nacer prematuros, tanto PIG (78,1) como AIG (apropiado para la edad gestacional: 61,1), en todas las edades específicas. Hubo reducciones significativas en la supervivencia en comparación con el término AIG bajo peso al nacer nos nacidos vivos. Las prevalencias estimadas mostraron valores inferiores a los de otros estudios, en parte debido a los criterios de exclusión adoptados. Los fenotipos neonatales identificó a los niños más vulnerables y con mayor riesgo de muerte. La prematuridad contribuyó más a la mortalidad que la condición PIG, y su prevención es necesaria para reducir la mortalidad neonatal en el Estado de Río de Janeiro.

This study investigated the magnitude and trends of cause-specific mortality among children 5 to 14 years of age in the state of Rio de Janeiro (RJ) from 2000 to 2019. We performed an ecological study, using data from the Mortality Information System (MIS). We calculated mortality rates per 100,000 children by chapters, groups, and categories of causes of death (ICD-10). Trends were estimated by joinpoint regression. Mortality rates among children aged 10 to 14 years were higher than those among children 5 to 9. The five leading causes of death were the same in both age groups, but they ranked differently. The two leading ones were external causes and neoplasms (31% and 15% among children aged 5 to 9 years; 45% and 11% among children aged 10 to 14 years). Among children 5 to 9 years, the mortality trend showed an annual decline (8%) from 2011 to 2015. Among children aged 10 to 14 years, the annual decline was 1.3% from 2000 to 2019. Mortality due to external causes decreased in both age groups, except for the category "Assault by unspecified firearm" (boys, 10 to 14 years) and "Unspecified drowning and submersion" (boys, 5 to 9 years). Mortality caused by neoplasms remained steady in both age groups. Infectious and respiratory diseases decreased differently between the two groups. Most causes of death are preventable or treatable, indicating the need for health and intersectoral investments.
Objetivou-se investigar a magnitude e a tendência da mortalidade de crianças de 5 a 14 anos por causas, no estado do Rio de Janeiro, de 2000 a 2019. Estudo ecológico de tendência temporal utilizando dados do Sistema de Informações sobre Mortalidade (SIM). Calcularam-se taxas de mortalidade por 100 mil crianças, por capítulos, grupos e categorias (CID-10). Estimou-se a série temporal por regressão joinpoint. As taxas de mortalidade de 10 a 14 anos foram superiores às da faixa de 5 a 9 anos. As cinco principais causas foram as mesmas de 5 a 14 anos, com diferente ordem de importância. As duas principais foram causas externas e neoplasias (31% e 15% para 5 a 9 anos; 45% e 11% para 10 a 14 anos). De 5 a 9 anos, a tendência da mortalidade teve declínio anual (8%) entre 2011 e 2015. De 10 a 14 anos, o declínio anual foi 1,3%, de 2000 a 2019. A mortalidade por causas externas decresceu em ambas as faixas, menos para a categoria "Agressão por arma de fogo" (meninos,10-14 anos) e "Afogamento" (meninos, 5-9 anos). A mortalidade por neoplasias ficou estável para todos. Doenças infecciosas e respiratórias decresceram de forma diferenciada entre os grupos. A maioria das causas de morte é evitável ou tratável, apontando necessidade de investimentos em saúde e intersetoriais.

OBJECTIVE: To analyze the causes of age-specific neonatal deaths and death-associated factors in the 2021 state of Rio de Janeiro birth cohort. METHODS: Retrospective cohort of live births (LB) followed up to 27 days of delivery (<24hs, 1-6 and 7-27 days). Data obtained from the Information Systems on Live Births (2021) and Mortality (2021/2022). We described the distributions of maternal and newborn characteristics and causes of death. We used multinomial regression models with hierarchical levels of determination of neonatal death. RESULTS: Of the 179,837 LB, 274 died within 24 hours, 447 within 1-6 days and 324 within 7-27 days. The neonatal mortality rate was 5.8 LB (CI 95%: 5.5-6.2). Neonatal survivors and deaths were heterogeneous according to the analyzed characteristics, except for the reproductive history (p<0,05). 78% of causes of death were avoidable. Causes reducible by adequate care for pregnant women (<24 hours and 1-6 days) and newborns (7-27 days) predominated. Low schooling showed a significant association for deaths between 7-27 days (ORajusted=1.3); mixed race, for deaths between 1-6 days (ORajusted=1.3), and black color for both age groups (1-6 days: ORajusted=1.5 and 7-27 days: ORajusted=1.8). Health care and biological factors of LB (intermediate and proximal levels) remained strongly associated with neonatal death, regardless of age. CONCLUSION: Causes of death, factors associated with neonatal death, and strength of association differed according to death-specific age. Preventive actions for neonatal death should consider sociodemographic vulnerabilities and intensify adequate prenatal and perinatal care.

OBJECTIVE: The aim of this study was to investigate factors associated with neonatal near miss and mortality of the live birth cohort in the city of Rio de Janeiro, Brazil, in 2015. METHODS: Population-based retrospective cohort of live births (LB) of single pregnancy with 0-27 days of follow-up. Data were obtained from the Brazilian Live Birth and Mortality Information Systems. Logistic regressions with the analytical strategy of hierarchical determination were used for cases of near miss and deaths separately. RESULTS: The cohort was composed of 85,850 LB. For every one thousand LB, about 16 were cases of near miss and six died. Maternal level of education, skin color, and age and adequacy of prenatal care were associated with neonatal near miss; for deaths, presentation of LB at delivery, birth weight, gestational age, and five-minute Apgar score are added. CONCLUSIONS: Besides confirming the effect of low birth weight, prematurity, and asphyxia on neonatal death, socioeconomic vulnerability markers - low education level and brown or black skin colors - were associated with neonatal death and near miss. Absent or inadequate prenatal care showed a strong association with both outcomes, being stronger for neonatal death. Investments in the quality of prenatal care and reduction of disparities in health care are necessary in Rio de Janeiro.

OBJECTIVE: To analyze trends in sociodemographic inequalities in the access to and use of prenatal care in Baixada Litorânea, a region of the state of Rio de Janeiro, Brazil, 2000-2020. METHODS: This was an ecological time-series study of the number of visits and adequacy of access to prenatal care. Absolute (differences) and relative (ratios) inequalities were calculated between extreme categories of variables; trends were estimated using joinpoint regression. RESULTS: A total of 185,242 pregnant women were studied. A proportion of ≥ 7 visits increased annually by 2.4% (95%CI 1.1;3.7) between 2013 (54.4%) and 2020 (63.4%), stable for less than eight years of schooling. Adequacy of access increased 2.6% (95%CI 1.2;4.0) between 2014 and 2020, stable for women ≥ 35 years old and schooling ≥ 12 years. Absolute inequalities decreased (between 3.5% and 6.4%) for age and race/skin color, and relative inequalities decreased (between 7.7% and 20.0%) for all variables. CONCLUSION: Access and number of prenatal consultations increased, however, remained lower for adolescents, women with low level of schooling and those of Black and mixed race/skin color.

BACKGROUND: International ecological studies have shown a positive association between infant mortality as a proxy for low birth weight and cardiovascular disease mortality in adult life. METHODS: Mortality rates due to Cardiovascular Diseases (CVDMR) standardised by age in adults between 45 and 69 years of age and by place of birth (pob) and residence (res) were related to Infant Mortality Rates (IMR) in the Brazilian 1935 birth cohort. RESULTS: Two relationship patterns were noted between IMR and CVDMR: for the Southeast, South and Centre-West group of regions (r(pob)=0.46; r(res)=0.29) and for the North and Northeast group of regions (r(pob)=0.21; r(res)=0.33). For the latter pattern, two states were identified (Rio Grande do Norte and Paraíba) as atypical areas, whose exclusion strengthened the association (r(pob)=0.73; r(res)=0.91). CONCLUSIONS: The direction of the associations changed after the analysis by group of Brazilian regions (indirect control of socio-economic levels, coverage and quality of the information). There is a positive, although weak association between IMR and CVDMR. Attempts to control or minimise the interference of migratory movements, cohort effects and socio-economic levels represented methodological progress in ecological analyses of foetal programming in Brazil.

OBJECTIVE: To estimate trends of fetal (FMR) and neonatal (NMR) mortality rates due to avoidable causes and maternal education in the city of Rio de Janeiro (2000-2018). METHODS: Ecological time series study. Mortality and Live Birth Information System Data. The List of Avoidable Causes of Death Due to Interventions of the Brazilian Health System was used for neonatal deaths and an adaptation for fetal deaths, according to maternal education indicators (low <4 and high ≥12, years of study). Joinpoint regression models were used to estimate trends in FMR, based on one thousand births, and NMR, based on one thousand live births. RESULTS: FMR decreased from 11.0 to 9.3% and NMR from 11.3 to 7.8% (2000/2018). In 2006, FMR (10.5%) exceeded NMR (9.0%), remaining higher. From 2000 to 2018, the annual decrease of FMR was 0.8% (2000 to 2018) and of NMR, 3.8% until 2007, decreasing to 1.1% by 2011; from then on, it remained stable. Avoidable causes, especially those reducible by adequate prenatal care, showed higher rates. Both FMR and NMR for low-education women were higher than those for the high-education level, the difference being much more pronounced for FMR, and at the end of the period: low- and high-education FMR were respectively 16.4 and 4.5% (2000) and 48.5 and 3.9% (2018), and for NMR, 18.2 and 6.7% (2000) and 28.4 and 5.0% (2018). CONCLUSION: The favorable trend of decreasing mortality was not observed for children of mothers with low education, revealing inequalities. The causes were mostly avoidable, being related to prenatal care and childbirth.

Although the Brazilian List of Avoidable Causes of Deaths (LBE in Portuguese), in its version for children under 5 years of age (LBE < 5), does not include stillbirths, some studies have used the list with or without adaptations. We present a proposal for adaptation of the LBE for stillbirths (LBE-OF in Portuguese) and the results of its application to stillbirths in the State of Rio de Janeiro, Brazil, in 2018, compared to the results with LBE < 5. We reviewed the categories from the 10th revision of the International Classification of Diseases (ICD-10) in the LBE < 5 and reassigned them in the avoidability groups, according to time of death in relation to delivery and the causes consistent with stillbirths. Conditions that did not elucidate the determinants of death were allocated as ill-defined causes. Stillbirths in the State of Rio de Janeiro, selected from the databases of the Mortality Information System (SIM in Portuguese), were classified according to LBE-OF and LBE < 5. When classifying the 2,585 stillbirths that occurred in the State of Rio de Janeiro in 2018, we found that according to LBE < 5, there were predominantly causes "reducible by adequate care in labor and delivery" (42.9%), while according to LBE-OF, the most frequent causes were "reducible by adequate care for during pregnancy" (43.6%). Ill-defined causes ranked second according to the LBE-OF (35.4%) and third according to LBE < 5. Some 30% of stillbirths changed groups and subgroups of avoidability, showing greater consistency with the profile of obstetric care. Although identifying a higher percentage of ill-defined causes, the LBE-OF is more consistent with the pathophysiology of fetal deaths. The inclusion of stillbirths in the SIM would be a positive step in monitoring and upgrading the investigation of causes of fetal death.
Apesar da Lista Brasileira de Causas de Morte Evitáveis (LBE), na sua versão para crianças menores de 5 anos (LBE < 5), não contemplar óbitos fetais, alguns estudos a utilizaram sem ou com poucas adaptações. Apresentamos uma proposta de adaptação da LBE para óbitos fetais (LBE-OF) e os resultados de sua aplicação aos óbitos fetais no Estado do Rio de Janeiro, Brasil, em 2018, comparados aos da LBE < 5. Revisamos as categorias da 10ª revisão da Classificação Internacional de Doenças (CID-10) presentes na LBE < 5 e as realocamos nos grupos de evitabilidade, segundo momento do óbito em relação ao parto e as causas condizentes com óbitos fetais. Condições que não esclarecem os determinantes do óbito foram alocadas como causas mal definidas. Óbitos fetais no Estado do Rio de Janeiro - selecionados das bases do Sistema de Informações sobre Mortalidade (SIM) - foram classificados segundo LBE-OF e a LBE < 5. Ao classificar os 2.585 óbitos fetais do Estado do Rio de Janeiro ocorridos em 2018, observou-se que, segundo a LBE < 5, predominariam causas "reduzíveis por adequada atenção ao parto" (42,9%), já pela LBE-OF, aquelas "reduzíveis por adequada atenção à mulher na gestação" foram as mais frequentes (43,6%). As causas mal definidas ocuparam a segunda posição segundo a LBE-OF (35,4%) e a terceira posição segundo LBE < 5. Cerca de 30% dos óbitos fetais mudaram de grupos e subgrupos de evitabilidade, mostrando maior coerência com o perfil de atenção obstétrica. Embora identificando um maior percentual de causas mal definidas, a LBE-OF coaduna-se mais com a fisiopatologia dos óbitos fetais. Sua inserção no SIM avançaria no sentido de monitorar e qualificar a investigação de causas de morte fetal.

Revisamos las categorías de la 10ª revisión de la Clasificación Internacional de Enferemedades (CIE-10) presentes en la LBE < 5, y las asignamos en los grupos de evitabilidad, según el momento del óbito, en relación con el parto y las causas acordes con óbitos fetales. Las condiciones que no aclararon los determinantes del óbito fueron asignadas como causas mal definidas. Los óbitos fetales del Estado de Río de Janeiro -seleccionados de las bases del Sistema de Información sobre Mortalidad (SIM)- se clasificaron según el LBE-OF y la LBE < 5. Al clasificar los 2.585 óbitos fetales del Estado de Rio de Janeiro ocurridos en 2018, se observó que, según la LBE < 5 años, predominarían causas "reducibles por una adecuada atención al parto" (42,9%), mientras que por la LBE-OF, aquellas "reducibles por una adecuada atención a la mujer en la gestación" fueron las más frecuentes (43,6%). Las causas mal definidas ocuparon la segunda posición según la LBE-OF (35,4%), y la tercera posición según LBE < 5. Cerca de un 30% de los óbitos fetales cambiaron de grupos y subgrupos de evitabilidad, mostrando una mayor coherencia con el perfil de atención obstétrica. A pesar de haberse identificado un mayor porcentaje de causas mal definidas, la LBE-OF es más compatible con la fisiopatología de los óbitos fetales. Su inserción en el SIM avanzaría en el sentido de monitorear y calificar la investigación de causas de muerte fetal.

OBJECTIVE: To investigate the association between birth weight and excess weight among students aged 6-14 years, adjusted for life course confounding factors. METHODS: Cross-sectional study with 6-14-year-old schoolchildren in 2010; 795 school children from two public schools. In addition, a sub-sample was selected using a case-cohort study approach. Sociodemographic, breastfeeding, food introduction, previous weight gain, family history, current clinical and behavioral variables as well as maternal variables related to pregnancy, were collected. Multivariable weighted logistic regression was used to evaluate the association between birth weight and overweight. All prevalent cases of overweight (nâ¯=â¯160) were selected to compose the case group and a random sub-sample of all students participating in the study (nâ¯=â¯276 students, of whom 88 were cases) were the control group. RESULTS: An unadjusted 6% increase in the excess weight prevalence ratio (p-valueâ¯=â¯0.004) was found for each 100â¯g increase in birth weight. With adjustment for age, sex and behavioral variables (models 1 and 2), the association of birth weight with excess weight was positive and statistically significant, but it was no longer significant in the final model (model 3) when clinical variables were considered. CONCLUSIONS: Although some of the secondary associations were statistically significant, we could not identify a significant association between birthweight and excess weight in adolescents.

Objective to assess the applicability of the Brazilian List of Avoidable Causes of Death (BAL) to perinatal mortality in public maternity hospitals in the states of Rio de Janeiro (RJ) and São Paulo (SP) in 2011. Methods this was a descriptive case series study of perinatal deaths using primary data from the Mortality Information System; the BAL was applied, with adaptations (codes P20.9 and P70-74) and, in addition in Rio de Janeiro the Extended Wigglesworth (EW) Classification was also used. Results according to the BAL, 61.2% of the 98 perinatal deaths were avoidable, mainly by providing adequate attention to women in pregnancy; 'Ill-defined causes of death' accounted for 26.6% of cases, mainly fetal deaths; use of EW in RJ indicated that the 'Antepartum Fetal Death' category was predominant and was related to inadequate prenatal care; this was in line with the BAL. Conclusions after reallocating some codes, the BAL can improve fetal death evaluation, whereby studies with a larger number of participants are needed.

The regionalization of perinatal care should consider existing healthcare structures for facilitating access. This spatial-temporal ecological study identified intermunicipal flows of perinatal births and deaths in Greater Metropolitan Rio de Janeiro, Brazil, in 2011 and 2014, defined parameters, and systematized proposals for organizing the regionalization of perinatal care. The data sources were the Brazilian Information System on Live Births, Mortality Information System, National Registry of Healthcare Establishments, and 2010 Population Census. The study identified existing relations between the mothers' municipalities of residence and the occurrence of perinatal births and deaths. Each municipality was analyzed singly and pairwise (residence/occurrence) according to the vital event, healthcare resources, and pragmatic criteria of life-threatening conditions at birth. We conducted descriptive analyses of dominant flows, exploratory principal components analysis, and cluster analysis. The existing healthcare networks were identified, and 47 variables were summarized in three factors (analytical dimensions) - availability of beds, risk of life-threatening conditions, and socioeconomic status - accounting for 60%/80%, 20%/30%, 13%/22%, respectively, of the variance pertaining to each year analyzed. The factors were used to form clusters, classified in 3 to 5 strata. Three proposals were drafted for perinatal health regions. The study's principal contribution was having presented parameters for monitoring the regionalization and systematic reevaluation of this process based on administrative records.
A regionalização do cuidado perinatal deve considerar as estruturas assistenciais existentes e facilitar o acesso. Este estudo identificou fluxos assistenciais intermunicipais de nascimentos e óbitos perinatais ocorridos na Região Metropolitana do Rio de Janeiro, Brasil, em 2011 e 2014, definiu parâmetros e sistematizou propostas para a organização da regionalização da assistência perinatal. Estudo ecológico espaço-temporal. As fontes de dados foram os Sistemas de Informações sobre Nascidos Vivos e sobre Mortalidade, o Cadastro Nacional de Estabelecimentos de Saúde e o Censo Demográfico de 2010. Foram identificadas relações existentes entre municípios de residência e ocorrência dos nascimentos e óbitos perinatais. Cada município foi analisado em separado e em pares - residência/ocorrência - segundo o evento vital, recursos assistenciais e critérios pragmáticos de ameaça à vida. Foram realizadas análises descritivas de fluxos dominantes, fatorial exploratória de componentes principais e cluster. Identificaram-se as redes assistenciais existentes, e as 47 variáveis analisadas foram resumidas em três fatores (dimensões analíticas) - disponibilidade de leitos, situação de ameaça à vida e condições socioeconômicas - responsáveis, respectivamente, por 60/80%, 20/30% e 13/22% da variância, relativas a cada ano analisado. Os fatores foram utilizados para a formação dos clusters, classificados de 3 a 5 estratos. Três propostas de regiões de saúde perinatal foram elaboradas. A principal contribuição deste estudo foi apresentar parâmetros para o acompanhamento da regionalização e a reavaliação desse processo sistematicamente com base nos registros administrativos.
La regionalización del cuidado perinatal debe considerar las estructuras asistenciales existentes y facilitar el acceso a las mismas. Este estudio identificó flujos asistenciales intermunicipales de nacimientos y óbitos perinatales, ocurridos en la región metropolitana de Río de Janeiro, Brasil, en 2011 y 2014, definió parámetros y sistematizó propuestas para la organización de la regionalización de la asistencia perinatal. Se trata de un estudio ecológico espacio-temporal. Las fuentes de datos fueron: Sistema de Información sobre Nacidos Vivos y sobre Mortalidad, registro nacional de establecimientos de salud y Censo Demográfico de 2010. Se identificaron las relaciones existentes entre municipios de residencia y ocurrencia de nacimientos y óbitos perinatales. Cada municipio se analizó por separado y por pares -residencia/ocurrencia-, según el evento vital, recursos asistenciales y criterios pragmáticos de amenaza para la vida. Se realizaron análisis descriptivos de flujos dominantes, así como análisis factoriales exploratorios de componentes principales y clúster. Se identificaron las redes asistenciales existentes y las 47 variables analizadas se resumieron en tres factores (dimensiones analíticas): disponibilidad de camas, situación de amenaza para la vida y condiciones socioeconómicas; responsables respectivamente de un 60%/80%, 20%/30% y 13%/22%, de la variancia, relativas a cada año analizado. Los factores fueron utilizados para la formación de los clústeres, clasificados de entre 3 a 5 estratos. Se elaboraron tres propuestas de regiones de salud perinatal. La principal contribución de este estudio fue presentar parámetros para realizar un seguimiento de la regionalización, así como la reevaluación de este proceso sistemáticamente, a partir de registros administrativos.

The study describes the characteristics of maternal deaths in the city of Rio de Janeiro, Brazil, during 2000-2003. After investigation by public-health services, 217 maternal deaths were identified among predominantly non-white (48.9%), single (57.1%) women aged 29.6 +/- 7.3 years on average. Direct obstetric causes corresponded to 77.4% of the maternal deaths, mainly due to hypertensive disorders. HIV-related diseases accounted for 4% of the maternal deaths. Almost three-fourths of the mothers who died were aged 20-39 years, although the highest risk of maternal death corresponded to the age-group of 40-49 years (248.9 per 100,000 livebirths). The socioeconomic and demographic profiles of maternal deaths in the city of Rio de Janeiro reflected a vulnerable social situation. Appropriate interventions aimed at reducing maternal mortality need to encompass all women of childbearing age, irrespective of the magnitude of the risk of maternal death.

Abstract Objectives: to analyze neonatal deaths according to avoidability and to analyze the temporal trend of neonatal mortality rate (NMR) in Niterói/RJ, 2012-2022. Methods: ecological time series study. Data from Sistema de Informação sobre Nascidos Vivos and Sistema de Informação sobre Mortalidade. NMRs were calculated according to maternal and neonatal variables and trends were estimated using the joinpoint regression. Results: the annual number of live births (LB) fell, with a decreasing trend among adolescents and those with low education level. Of the 324 deaths, most occurred early (0-6 days), by preventable causes in 68.6%, predominating those reducible by adequate care during pregnancy. The overall NMR remained stable, ranging from 4.2 to 6/1,000 LB, being higher at the extremes of maternal age (12.7 and 8.6/1,000 LB in 2022, adolescents and over 35 years old, respectively), in low education level mothers (27.6/1,000 LB in 2022), in neonates <1,500g and <32 weeks (293.1 and 250/1,000 LB in 2022, respectively). NMR trend was upward in low schooling women, white-colored, adolescents and those ≥35 years, in babies weighing <1,500g and >2,500g, and for avoidable causes. Conclusions: the high proportion of preventable causes reveals the reduction potential. There was inequality in NMR and its trend, demanding more equitable health actions.
Resumo Objetivos: analisar os óbitos neonatais segundo evitabilidade e a tendência temporal da taxa de mortalidade neonatal (TMN) em Niterói/RJ, de 2012-2022. Métodos: estudo ecológico de série temporal. Dados provenientes do Sistema de Informações sobre Nascidos Vivos e Sistema de Informação sobre Mortalidade. As TMN foram calculadas segundo variáveis maternas e neonatais e as tendências estimadas pela regressão joinpoint. Resultados: o número anual de nascidos vivos (NV) diminuiu, com tendência decrescente entre mães adolescentes e de baixa escolaridade. Dos 324 óbitos, a maioria ocorreu precocemente, por causas evitáveis (68,6%), predominando aquelas reduzíveis por adequada atenção à gestação. A TMN global mostrou estabilidade, entre 4,2 e 6,0/1000NV, mais elevada nos extremos etários maternos (12,7 e 8,6/1.000 NV em 2022, adolescentes e maiores de 35 anos, respectivamente), nas mães com baixa escolaridade (27,6/1.000 NV em 2022), nos neonatos <1.500g e <32 semanas (293,1 e 250/1.000 NV em 2022, respectivamente). A tendência da TMN foi crescente entre mulheres de baixa escolaridade, brancas, adolescentes e ≥35 anos, nas faixas de peso <1.500g e >2.500g, e por causas evitáveis. Conclusões: a elevada proporção de causas evitáveis revela o potencial de redução. Houve desigualdade da TMN e sua tendência, demandando ações de saúde mais equânimes.

OBJECTIVE: to analyze the incompleteness of variables retrieved from the Live Birth Information System (SINASC) and the Mortality Information System (SIM), in the State of Rio de Janeiro, in the time series 1999 to 2014. METHODS: this was a time series study of SINASC and SIM; the Romero & Cunha score was used to analyze incompleteness; Joinpoint regression was used to analyze temporal trend; in 2014, deaths were evaluated separately according to investigation. RESULTS: regarding SINASC variables, in 1999 marital status (37.40%), number of stillborn children (31.30%), and race/skin color (24.63%) had the highest incompleteness percentages; in 2014, no variable exceeded 5% incompleteness, except occupation; regarding SIM variables, in 1999 five variables exceeded 20%, and missing data for previous stillborn children was over 60%; in 2014, only one variable exceeded 20% incompleteness; investigated deaths had better completeness. CONCLUSION: both systems were found to have improved; the quality of SINASC completeness remained superior to that of SIM.

Despite the reduction in under-five mortality, the causes are still mostly avoidable, and survival may be compromised by life-threatening conditions at birth. The study estimated the burden of life-threatening conditions at birth, neonatal near miss, and mortality, with an emphasis on avoidable causes, as well as under-five survival in live birth cohorts. This was a retrospective cohort study of live birth in the city of Rio de Janeiro, Brazil (2012-2016). The databases from the Brazilian Information System on Live Births and the Brazilian Mortality Information System were linked. Pragmatic criteria were used to define life-threatening conditions and near miss. Deaths were classified according to the Brazilian list of causes of avoidable deaths. Morbidity and mortality and survival indicators were estimated (Kaplan-Meier). Of the 425,505 live birth , 2.2% presented life-threatening conditions at birth. The under-five, infant and neonatal mortality rates were 0.01, 0.06, and 14.97 per 1,000 person-days, respectively. Avoidable, unclearly avoidable, and ill-defined causes accounted respectively for 61%, 35%, and 4% of the deaths. The risk of death from avoidable causes attributable to life-threatening conditions at birth was 97.6%. Survival was lower in newborns with life-threatening conditions compared to those without life-threatening conditions. The pragmatic criteria for life-threatening conditions determined the profile of proportional mortality by causes of death according to the three groups of causes in the Brazilian list of causes of avoidable deaths. Life-threatening conditions at birth increases the risk of morbidity and mortality in under-five children and raises the discussion on vulnerability and the need for care for these children and social support for their families.
Apesar da redução da mortalidade na infância, as causas ainda são majoritariamente evitáveis, e a sobrevida pode estar condicionada à situação de ameaça à vida ao nascer. Foram estimadas a carga de ameaça à vida ao nascer, de near miss neonatal, e a mortalidade, com ênfase na evitabilidade, e sobrevida na infância, em coortes de nascidos vivos. Estudo de coorte retrospectiva de nascidos vivos residentes no Município do Rio de Janeiro (2012-2016). Os bancos de dados dos Sistemas de Informações sobre Nascidos Vivos e sobre Mortalidade foram relacionados. Critérios pragmáticos foram utilizados para definir ameaça à vida e near miss. Óbitos foram classificados segundo a lista brasileira de causas de mortes evitáveis. Foram estimados indicadores de morbimortalidade e a sobrevida (Kaplan-Meier). Dos 425.505 nascidos vivos, 2,2% apresentaram ameaça à vida ao nascer. As taxas de mortalidade na infância, infantil e neonatal foram, respectivamente: 0,01; 0,06 e 14,97 por mil pessoas-dia. Causas evitáveis, não claramente evitáveis e mal definidas corresponderam, respectivamente, a 61%, 35% e 4% dos óbitos. O risco de morte por causas evitáveis atribuível ao nascimento com ameaça à vida foi de 97,6%. A sobrevida foi menor entre recém-nascidos com ameaça à vida, comparados àqueles sem ameaça à vida. Os critérios pragmáticos de ameaça à vida determinaram o perfil de mortalidade proporcional por causas de morte segundo os três grupos de causas da lista brasileira de causas de mortes evitáveis. Nascer com ameaça à vida define crianças com maior risco de morbimortalidade e põe, em pauta, a discussão sobre a vulnerabilidade e as necessidades de assistência às crianças e do apoio social às suas famílias.
A pesar de la reducción de la mortalidad en la infancia, las causas de fallecimiento todavía son mayoritariamente evitables y la supervivencia puede estar condicionada con la situación de amenaza para la vida al nacer. En este trabajo se estimaron la carga de amenaza para la vida al nacer, el near miss neonatal y la mortalidad, con énfasis en la evitabilidad y supervivencia en la infancia en cohortes de nacidos vivos. Es un estudio de cohorte retrospectivo de nacidos vivos, residentes en el municipio de Río de Janeiro, Brasil (2012-2016). Se relacionaron los bancos de datos de los Sistemas de Información sobre Nacidos Vivos y sobre Mortalidad. Se utilizaron criterios pragmáticos para la definición amenaza para la vida al nacer y near miss. Los óbitos se clasificaron según la lista brasileña de causas de muertes evitables. Se estimaron indicadores de morbimortalidad y supervivencia (Kaplan-Meier). De los 425.505 nacidos vivos, un 2,2% presentaron amenaza para la vida. Las tasas de mortalidad en la infancia, infantil y neonatal fueron, respectivamente: 0,01; 0,06 y 14,97 por 1.000 personas-día. Las causas evitables, no claramente evitables y mal definidas, correspondieron, respectivamente, a un 61%, 35% y 4% de los óbitos. El riesgo de muerte por causas evitables atribuible al nacimiento con amenaza para la vida fue de un 97,6%. La supervivencia fue menor entre recién nacidos con amenaza para la vida, comparados con aquellos sin amenaza para la vida. Los criterios pragmáticos de amenaza para la vida determinaron el perfil de mortalidad proporcional por causas de muerte, según los tres grupos de causas de la lista brasileña de causas de muertes evitables. Nacer con amenaza para la vida define a los niños con un mayor riesgo de morbimortalidad y pone en relevancia la discusión sobre vulnerabilidad y necesidades asistenciales para los niños, así como el apoyo social a sus familias.

Resumo: A restrição do crescimento intrauterino e a prematuridade determinam o baixo peso ao nascer, e a combinação das três condições resulta em diferentes fenótipos neonatais que interferem na sobrevivência infantil. Foram estimadas a prevalência, a sobrevivência e a mortalidade neonatal, segundo os fenótipos neonatais, na coorte de nascidos vivos de 2021 no Rio de Janeiro, Brasil. Foram excluídos nascidos vivos de gravidez múltipla, com anomalia congênita, e com inconsistências nas informações de peso e idade gestacional. Foi utilizada a curva Intergrowth para classificar adequação do peso, e estimadas a mortalidade (< 24 horas, 1-6 e 7-27 dias) e sobrevida (Kaplan-Meier). Dos 174.399 nascidos vivos, 6,8%, 5,5% e 9,5% eram, respectivamente, baixo peso ao nascer, pequeno para idade gestacional (PIG) e prematuros. Entre nascidos vivos com baixo peso ao nascer, 39,7% eram PIG e 70%, prematuros. Os fenótipos neonatais foram heterogêneos segundo características maternas, do parto, da gestação e do recém-nascido. A taxa de mortalidade por 1.000 nascidos vivos foi elevada para neonatos de baixo peso ao nascer prematuros, tanto PIG (78,1) quanto AIG (adequado para idade gestacional: 61,1), em todas as idades específicas. Houve reduções significantes da sobrevida quando comparados aos nascidos vivos não baixo peso ao nascer, AIG termo. As prevalências estimadas mostraram menores valores que as de outros estudos, em parte pelos critérios de exclusão adotados. Os fenótipos neonatais identificaram crianças mais vulneráveis e com maior risco de morte. A prematuridade contribuiu mais para a mortalidade que a condição de PIG; sua prevenção é necessária para reduzir a mortalidade neonatal no Estado do Rio de Janeiro.

De los 174.399 nacidos vivos, 6,8%, 5,5% y 9,5% fueron, respectivamente, bajo peso al nacer, pequeños para la edad gestacional (PIG) y prematuros. Entre los bacidos vivos com bajo peso al nacer, el 39,7% eran PIG y el 70% prematuros. Los fenotipos neonatales fueron heterogéneos según las características maternas, del parto, del embarazo y del recién nacido. La tasa de mortalidad por 1.000 nacidos vivos fue alta para los neonatos bajo peso al nacer prematuros, tanto PIG (78,1) como AIG (apropiado para la edad gestacional: 61,1), en todas las edades específicas. Hubo reducciones significativas en la supervivencia en comparación con el término AIG bajo peso al nacer nos nacidos vivos. Las prevalencias estimadas mostraron valores inferiores a los de otros estudios, en parte debido a los criterios de exclusión adoptados. Los fenotipos neonatales identificó a los niños más vulnerables y con mayor riesgo de muerte. La prematuridad contribuyó más a la mortalidad que la condición PIG, y su prevención es necesaria para reducir la mortalidad neonatal en el Estado de Río de Janeiro.
Abstract: Intrauterine growth restriction and prematurity determine low birth weight. The combination of the three conditions results in different neonatal phenotypes that interfere with child survival. Neonatal prevalence, survival and mortality were estimated according to neonatal phenotypes in the cohort of live births in 2021 in the state of Rio de Janeiro, Brazil. In this study, live births of multiple pregnancies, with congenital anomalies and inconsistencies in the information of weight and gestational age were excluded. The Intergrowth curve was used to classify weight adequacy. Mortality (< 24 hours, 1-6 and 7-27 days) and survival (Kaplan-Meier) were estimated. In total, 6.8%, 5.5%, and 9.5% of the 174,399 live births were low birth weight, small for gestational age (SGA), and premature, respectively. Considering low birth weight live births, 39.7% were SGA and 70% were premature. The neonatal phenotypes were heterogeneous according to maternal, delivery, pregnancy, and newborn characteristics. The mortality rate per 1,000 live births was high for low birth weight premature newborns, both SGA (78.1) and AGA (adequate for gestational age: 61.1), at all specific ages. Reductions in the survival rate were observed when comparing non-low birth weight and AGA term live births. The estimated prevalence values were lower than those of other studies, partly due to the exclusion criteria adopted. The neonatal phenotypes identified children who were more vulnerable and at higher risk of death. Prematurity contributed more to mortality than SGA, and its prevention is necessary to reduce neonatal mortality in the state of Rio de Janeiro.
RESUMO
Abstract Objective: The aim of this study was to investigate factors associated with neonatal near miss and mortality of the live birth cohort in the city of Rio de Janeiro, Brazil, in 2015. Methods: Population-based retrospective cohort of live births (LB) of single pregnancy with 0-27 days of follow-up. Data were obtained from the Brazilian Live Birth and Mortality Information Systems. Logistic regressions with the analytical strategy of hierarchical determination were used for cases of near miss and deaths separately. Results: The cohort was composed of 85,850 LB. For every one thousand LB, about 16 were cases of near miss and six died. Maternal level of education, skin color, and age and adequacy of prenatal care were associated with neonatal near miss; for deaths, presentation of LB at delivery, birth weight, gestational age, and five-minute Apgar score are added. Conclusions: Besides confirming the effect of low birth weight, prematurity, and asphyxia on neonatal death, socioeconomic vulnerability markers - low education level and brown or black skin colors - were associated with neonatal death and near miss. Absent or inadequate prenatal care showed a strong association with both outcomes, being stronger for neonatal death. Investments in the quality of prenatal care and reduction of disparities in health care are necessary in Rio de Janeiro.
Resumo Objetivo: Investigar fatores associados aos near miss e óbito neonatais na coorte de nascidos vivos do município do Rio de Janeiro (RJ), 2015. Métodos: Coorte retrospectiva de base populacional de nascidos vivos de gravidez única com seguimento de até 27 dias. Dados obtidos dos Sistemas de Informações sobre Nascidos Vivos e sobre Mortalidade. Foram usadas regressão logística e estratégia analítica de determinação hierárquica separadamente para casos de near miss e óbitos. Resultados: Coorte composta de 85.850 nascidos vivos. Para cada mil nascidos vivos, 16 foram casos de near miss e seis evoluíram para óbito. Escolaridade, cor da pele e idade maternas e adequação do pré-natal estiveram associadas ao near miss neonatal; para óbitos, acrescenta-se apresentação do NV no parto, peso, idade gestacional e Apgar no 5º minuto. Conclusões: Além de confirmar o efeito do baixo peso, da prematuridade e da asfixia no óbito neonatal, variáveis marcadoras de vulnerabilidade socioeconômica — baixa escolaridade e cor da pele parda ou preta — mostraram-se associadas ao óbito e ao near miss neonatal. Pré-natal ausente ou inadequado mostrou forte associação com ambos os desfechos, mais intensa para o óbito. Investimentos na qualificação do pré-natal e na redução das desigualdades na saúde são necessários no Rio de Janeiro.
RESUMO
Abstract Objectives: to estimate the burden of parturients, fetuses and neonate's severe morbidity and mortality and investigate the association between maternal and their conceptus outcomes. Methods: retrospective cohort of 546 parturients and their conceptus in a university hospital, reference for high-risk pregnancy, in the metropolitan region II of Rio de Janeiro State from 2015 to 2017. We classified parturients according to obstetric morbidity (OM) in direct, indirect, or mixed, and their outcomes as: 1) no severity, 2) severe complication (SC), 3) critical intervention/Intensive Care Unit, and 4) greater severity -maternal near-miss (MNM) or death. We evaluated the conceptus as neonatal near-miss (NNM) and fetal and neonatal deaths. We estimated morbimortality indicators and associated factors (multinomial logistic regression). Results: OM was frequent: 29.3% indirect, 22.3% direct, and 15.8% mixed. There were eight cases of NMM, seven with direct MO. Among the conceptus: 7.5% were NNM cases and 4.4%, deaths. The risk of severe maternal outcomes was 16.8 and neonatal, 102.6/1000 live births. Mixed race, inadequate prenatal care, CG and NMM/death, were associated with NNM. Inadequate prenatal care and maternal NM/death were associated with conceptus deaths. Conclusion: even in a reference unit, sociodemographic, and health care inequalities negatively affect mothers and, consequently, their children.
Resumo Objetivos: estimar a carga de morbidade grave e mortalidade em parturientes, fetos e neonatos e investigar a associação entre os desfechos maternos e de seus conceptos. Métodos: coorte retrospectiva de 546 parturientes e seus conceptos no hospital universitário referência para gravidez de alto risco da região metropolitana II do estado do Rio de Janeiro (ERJ), de 2015 a 2017. Classificamos as parturientes segundo morbidade obstétrica (MO) em direta, indireta e mista, e seus desfechos como: 1) sem gravidade, 2) complicação grave (CG), 3) intervenção crítica/ Unidade Terapia Intensiva e 4) maior gravidade-near miss materno (NMM) ou óbito. Avaliamos os conceptos quanto a near miss neonatal (NMN), óbitos fetais e neonatais. Estimamos indicadores de morbimortalidade, e fatores de associação (regressão logística multinomial). Resultados: MO foi frequente: 29,3% indiretas, 22,3% diretas e 15,8% mista. Ocorreram oito casos de NMM, sete com MO direta. Entre os conceptos,7,5% foram casos de NMN e 4,4%, óbitos. O risco de desfecho grave materno foi 16,8 e neonatal, 102,6 p/1000 nascidos vivos. Estiveram associados ao NMN: cor parda, pré-natal inadequado, CG e NMM/óbito; e ao óbito do concepto: pré-natal inadequado e NMM/óbito. Conclusão: mesmo em situação de referência, desigualdades sociodemográficas e assistenciais afetam negativamente mães e, consequentemente, seus conceptos.
