[Inequalities in congenital syphilis trends in the city of Niterói, Brazil, 2007-2016Desigualdades en la tendencia de sífilis congénita en la ciudad de Niterói, Brasil, 2007-2016]. / Desigualdades na tendência da sífilis congênita no município de Niterói, Brasil, 2007 a 2016.

OBJECTIVE: To describe the temporal distribution and epidemiologic characteristics of congenital syphilis (CS) cases in the city of Niterói, southeastern Brazil, from 2007 to 2016. METHOD: This descriptive time series analysis of the incidence of CS used data from the Notifiable Diseases Information System (SINAN) and the Live Birth Information System (SINASC). The sample included all notified cases. A probabilistic matching was performed between SINAN and SINASC data to recover ignored information. The time series was estimated using logarithmic regression according to sociodemographic and prenatal care variables. RESULTS: There were 754 identified cases of CS in the study period (mean incidence: 11.9 cases/1 000 live births). The incidence was higher in younger women (10 to 19; 20 to 24 years) and in those with black skin, low schooling, and without prenatal care. Of the overall group, only 57.6% received a diagnosis of syphilis during prenatal care. Treatment was not adequate in 87,7%, and only 12.2% of partners were treated. SC incidence presented a growing trend of 16%/year, reaching 23.2 cases/1 000 living births in 2016. This growth was especially marked in female adolescents (25.2%/year), brown race/skin color (16.8%/year), women with low schooling (57.1%/year) and women who received prenatal care (17.3%/year); and, from 2012 to 2016, in women without information on skin color. CONCLUSIONS: Social inequalities were linked to CS in the present sample. Also, increasing CS incidence was detected in youth. Health care professionals must be trained to manage gestational syphilis, and public policies must effectively address the social determinants of this condition.

OBJETIVO: Describir la distribución temporal y las características epidemiológicas de la sífilis congénita en Niterói, sureste de Brasil, de 2007 a 2016. MÉTODOS: Estudio descriptivo de series temporales sobre la incidencia de la sífilis congénita; se utilizaron datos del Sistema de Información de Enfermedades Notificables (SINAN) y del Sistema de Información de Nacimientos Vivos (SINASC). La muestra incluyó todos los casos reportados. Se realizó además una relación probabilística entre el SINAN y el SINASC para recuperar información ignorada. La serie temporal se estimó mediante regresión logarítmica, según variables sociodemográficas y prenatales. RESULTADOS: En el período estudiado se identificaron 754 casos de sífilis congénita (incidencia media de 11,9 casos/1 000 nacidos vivos). La incidencia fue mayor en las mujeres jóvenes (10-19, 20-24 años), mujeres de raza negra, con baja escolaridad y sin atención prenatal. Del total de mujeres, sólo se realizó el diagnóstico de sífilis durante la atención prenatal en 57,6%. El tratamiento fue inadecuado en 87,7% de las mujeres, solo el 12,2% de las parejas fueron tratadas. La enfermedad presentó una tendencia creciente (16%/año), y alcanzó 23,2 casos/1 000 nacidos vivos en 2016. El aumento fue más pronunciado en las adolescentes (25,2%/año), raza/color de piel morena (16.8%/año), mujeres con baja educación (57,1%/año), mujeres que recibieron atención prenatal (17,3%/año) y, de 2012 a 2016, en mujeres sin información sobre el color de la piel. CONCLUSIONES: En esta muestra se destacaron las desigualdades sociales en la aparición de sífilis congénita, con una incidencia creciente en las jóvenes. Se requiere capacitación de los profesionales de la salud en el manejo de la sífilis gestacional y la acción efectiva de políticas públicas sobre los determinantes sociales de la sífilis.

Smoking prevalence, reduction, and cessation during pregnancy and associated factors: a cross-sectional study in public maternities, Rio de Janeiro, Brazil.

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, prematurity, and low birth weight: risk phenotypes of neonatal death, Rio de Janeiro State, Brazil. / Restrição do crescimento intrauterino, prematuridade e baixo peso ao nascer: fenótipos de risco de morte neonatal, Estado do Rio de Janeiro, Brasil.

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.

La restricción del crecimiento intrauterino y la prematuridad determinan el bajo peso al nacer, y la combinación de las tres condiciones da como resultado diferentes fenotipos neonatales que interfieren en la supervivencia infantil. Se estimó la prevalencia, supervivencia y mortalidad neonatal según los fenotipos neonatales, en la cohorte de nacidos vivos en 2021 en el Estado de Río de Janeiro, Brasil. Se excluyeron nacidos vivos de embarazo múltiple, con anomalía congénita y con inconsistencias en la información sobre el peso y edad gestacional. Se utilizó la curva Intergrowth para clasificar la adecuación de peso, y se estimó la mortalidad (< 24 horas, 1-6 y 7-27 días) y supervivencia (Kaplan-Meier). 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.

Trends in prevalence of gastroschisis in Brazil from 2007 to 2020: A national population-based cross-sectional study.

BACKGROUND: Gastroschisis is a congenital abnormality of the abdominal wall which worldwide prevalence is increasing with time. Up to now, young maternal age is the main factor associated with gastroschisis. Brazil has a great proportion of adolescent mothers. OBJECTIVES: To estimate prevalence of gastroschisis in Brazil, explore the effect of very young maternal age, and analyze regional distribution and time trends. METHODS: Cross-sectional population-based study using data from official national information systems from 2007 to 2020, covering 9,831 gastroschisis cases. Low maternal age was assessed as risk factor through odds ratio. Prevalence time trends by maternal age and geographic area were analyzed using joinpoint regression. RESULTS: Overall prevalence of gastroschisis in Brazil was 2.47 per 10,000 births. From first to last biennium, there was a 23% relative increase. Last biennium prevalence was higher in the Central-west region and lower in the Northeast. Compared to mothers of 20-34 years old (YO), the odds-ratio for prevalence and 95% confidence intervals for gastroschisis were, as follows: (a) 10-14 YO-4.9 (4.3,5.5); (b) 15-19 YO-3.6 (3.5,3.8); and (c) 35-49 YO-0.3 (95% CI 0.3, 0.4). CONCLUSIONS: Prevalence of gastroschisis in Brazil relatively increased 23% from 2007 to 2020. This happened in all maternal age groups. Differences between regions may be associated to data quality. Young mothers had a higher prevalence of gastroschisis and still higher for those under 15 YO. Mother age over 34 YO was a protective factor.

Temporal trend of congenital syphilis in the most populous municipality of metropolitan region II of Rio de Janeiro state.

OBJECTIVE: This study aimed to explore the temporal trend in congenital syphilis, according to sociodemographic and prenatal care in the city of São Gonçalo - Rio de Janeiro, from 2007 to 2018. METHODS: Ecological time series study, with data from SINAN (Information System for Notifiable Diseases) and SINASC (Information System on Live Births databases). We calculated annual incidence (per 1,000 live births) according to sociodemographic and prenatal variables. For the same variables, we calculated trends by logarithmic regression (Joinpoint Regression), estimating the annual percentage change. RESULTS: A total of 2,420 cases were reported from 2007 to 2018, with an increasing trend: 64.9% per year (2010-2013) and 24.9% (2013-2018). In 2018, the highest rates were in adolescents (90.6/1,000 live births), black women (87.6/1,000 live births), low-educated women (122.8/1,000 live births), and those without prenatal care (677.4/1,000 live births). The annual percentage change of these categories was, respectively, 37.3% (2010-2018), 33.5% (2012-2018), 39.9% (2014-2018), and 85.0% (2011-2015), but all categories showed a crescent trend. CONCLUSIONS: We identified high congenital syphilis incidences and crescent trends, especially in more vulnerable groups, pointing to social and healthcare inequalities. Prenatal care needs to be more comprehensive and qualified, primarily for young, low-educated, and black women.

[Evolution of the completeness and consistency of the gastroschisis registry in the Brazilian Live Birth Information System, from 2005 to 2020]. / Evolução da completude e consistência do registro de gastrosquise no Sistema de Informações sobre Nascidos Vivos no Brasil, de 2005 a 2020.

This study aimed to evaluate the evolution of the completeness and consistency of the gastroschisis registry in the Brazilian Live Birth Information System (SINASC). It is a time-series study on the completeness of the variable "occurrence of congenital anomaly" and the consistency of gastroschisis diagnosis in SINASC, in biennia from 2005 to 2020, for federative units, region, and Brazil. The consistency was estimated by the ratio between deaths from gastroschisis registered in the Brazilian Mortality Information System (SIM) and the total number of cases recorded in SINASC. Temporal trend was analyzed by joinpoint regression. In the period, 46,574,995 live births and 10,024 cases of gastroschisis were recorded. A total of 5,632 infant deaths due to gastroschisis were identified. The percentage of incompleteness decreased from 6.52% to 1.87%, with an annual percentage variation (APV) of -14.5%, and completeness reached excellence (≤ 5% of incompleteness), except in the Central-West Region. Case/death ratios above 1 were found in the North and Northeast regions and in some federative units in the Central-West, but there was a decrease, approaching the mortality found in studies in the South and Southeast regions. Its reduction was more pronounced until 2009-2010 (APV = -10.7%) and smaller later (APV = -4.4%). The quality of the gastroschisis registry reflects regional differences in the overall quality of SINASC, constituting as a marker for malformations that require complex neonatal care.

O objetivo deste estudo foi avaliar a evolução da completude e da consistência do registro de gastrosquise no Sistema de Informações sobre Nascidos Vivos (SINASC) no Brasil. Trata-se de estudo de série temporal sobre a completude da variável "ocorrência de anomalia congênita" e a consistência do diagnóstico de gastrosquise no SINASC, nos biênios entre 2005 e 2020, para Unidades da Federação, região e Brasil. A consistência foi estimada pela razão entre óbitos por gastrosquise registrados no Sistema de Informações sobre Mortalidade (SIM) e o total de casos registrados no SINASC. A tendência temporal foi analisada por regressão joinpoint. No período, havia registro de 46.574.995 nascidos vivos e 10.024 casos de gastrosquise entre eles. Identificamos 5.632 óbitos infantis por gastrosquise. O percentual de incompletude diminuiu de 6,52% para 1,87%, com variação percentual anual (VPA) de -14,5%, e a completude atingiu a excelência (≤ 5% de incompletude), exceto no Centro-oeste do país. Razão óbito/caso acima de 1 foi encontrada nas regiões Norte e Nordeste e em alguns estados do Centro-oeste, mas houve diminuição, aproximando-se da mortalidade encontrada em estudos no Sul e Sudeste. Sua redução foi mais acentuada até 2009-2010 (VPA = -10,7%) e menor posteriormente (VPA = -4,4%). A qualidade do registro de gastrosquise reflete as diferenças regionais da qualidade geral do SINASC, configurando-se uma condição marcadora para malformações que demandam atenção neonatal complexa.

El objetivo de este estudio fue evaluar la evolución de la completitud y consistencia del registro de la gastrosquisis en el Sistema de Información de los Nacidos Vivos (SINASC) en Brasil. Se trata de un estudio de serie temporal sobre la completitud de la variable "aparición de anomalía congénita" y la consistencia del diagnóstico de gastrosquisis en el SINASC, en los bienios entre 2005 y 2020, en estados, regiones y Brasil. La consistencia se estimó por la razón entre las defunciones por gastrosquisis registradas en el Sistema de Información de Mortalidad (SIM) y el total de casos inscritos en el SINASC. La tendencia temporal se analizó mediante regresión joinpoint. Durante el período, hubo 46.574.995 nacidos vivos y 10.024 casos de gastrosquisis entre ellos. Identificamos 5.632 muertes infantiles por gastrosquisis. El porcentaje de incompletitud disminuyó de 6,52% a 1,87%, con una variación porcentual anual (VPA) de -14,5%, y la completitud alcanzó la excelencia (≤ 5% de incompletitud), excepto en la región Centro-oeste del país. Se encontró una relación defunciones/caso superior a 1 en las regiones Norte y Nordeste y en algunos estados del Centro-oeste, pero hubo una disminución, acercándose a la mortalidad encontrada en estudios en el Sur y Sudeste. Su reducción fue más pronunciada hasta 2009-2010 (VPA = -10,7%) y después menor (VPA = -4,4%). La calidad del registro de gastrosquisis refleja diferencias regionales relacionadas con la calidad general del SINASC, configurando una condición manifiesta de malformaciones que demandan cuidados neonatales complejos.

What do children aged 5 to 14 years die from in the state of Rio de Janeiro, Brazil? Trend analysis of the period 2000-2019. / De que morrem as crianças de 5 a 14 anos no estado do Rio de Janeiro? Análise do período 2000-2019.

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.

Knowledge about human papillomavirus transmission and prevention among physicians in Rio de Janeiro state, Brazil.

OBJECTIVE: This study aimed to assess physicians' knowledge about human papillomavirus infection and its prevention. METHODS: Descriptive web-based survey with 15 objective questions targeted to physicians affiliated with the Regional Council of Medicine from Rio de Janeiro state, Brazil. Participants were invited by e-mail and the Council social networks, between January and December 2019. RESULTS: The study sample had 623 participants, with a median age of 45 years, predominantly women (63%). The most frequent specialties were Obstetrics and Gynecology (21.1%), Pediatrics (11.2%), and Internists (10.5%). Concerning human papillomavirus knowledge, 27.9% of the participants were able to identify accurately all possible forms of transmission, and none of them could recognize all the risk factors of infection. Nevertheless, 95% recognized that asymptomatic infection could occur in both sexes. Regarding knowledge about clinical manifestations, diagnosis, and screening, only 46.5% were able to identify all human papillomavirus-related cancers, 42.6% were aware of the periodicity of Pap smears, and 39.4% indicated that serological test was not adequate for diagnosis. The recommended age group for human papillomavirus vaccination was recognized by 94% of the participants, as well as the need for a Pap smear and the use of condoms, even after vaccination. CONCLUSIONS: There is good knowledge about prevention and screening for human papillomavirus infections; many gaps were identified regarding transmission, risk factors, and associated diseases among physicians in Rio de Janeiro state.

Acute pulmonary histoplasmosis: a case series from an outbreak in Southeastern Brazil.

Histoplasmosis is a systemic mycosis prevalent in the Americas. Humans become infected via the respiratory route by inhaling aerosols from soil contaminated with bird and bat excretions. Acute pulmonary histoplasmosis is usually asymptomatic and is more often a self-limiting illness. We report a series of seven acute pulmonary cases in adults during an outbreak in Nova Friburgo city, Rio de Janeiro State, Brazil, in a group of volunteers who were cleaning an old, abandoned house without using personal protective equipment. The patients had a favorable evolution after suitable treatment, but all required hospitalization.

Relationship between ultra-processed foods and metabolic syndrome in adolescents from a Brazilian Family Doctor Program.

OBJECTIVE: To estimate the association between food intake and metabolic syndrome (MetS). DESIGN: Cross-sectional design conducted from July 2006 to December 2007. SETTING: Adolescents assisted by the Family Doctor Program (FDP) in Niterói, a metropolitan area in Rio de Janeiro State, Brazil. SUBJECTS: Survey of 210 adolescents. Individuals with three or more of the following components of MetS were classified as having this syndrome: TAG ≥ 110 mg/dl; HDL cholesterol < 50 mg/dl for girls aged 12-19 years and boys aged 12-14 years or <45 mg/dl for boys aged 15-19 years; waist circumference ≥75th percentile; serum glucose >100 mg/dl; and blood pressure ≥90th percentile. A semi-quantitative FFQ was used, and foods were grouped as: unprocessed or minimally processed foods (Group 1), processed culinary and food industry ingredients (Group 2) and ultra-processed foods (Group 3). The associations between food consumption and MetS were adjusted for sociodemographic, behavioural and family history covariates and were estimated using generalized estimation equations with the Poisson regression model. RESULTS: MetS was diagnosed in 6·7 % of the adolescents; the most frequent diagnostic criteria included the reduction of HDL cholesterol (46·7 %), elevated serum glucose (17·1 %) and the elevation of waist circumference (16·7 %). Crude analysis showed higher average daily intakes of energy, carbohydrates and ultra-processed foods among adolescents with MetS. After statistical adjustment, the intake of ultra-processed foods (≥3rd quartile) remained associated with MetS (prevalence ratio = 2·5; P = 0·012). CONCLUSIONS: High consumption of ultra-processed foods was associated with the prevalence of MetS in this adolescents group.

Age-specific neonatal mortality and associated factors in the 2021 state of Rio de Janeiro (Brazil) birth cohort.

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.

Neonatal near miss and mortality and associated factors: cohort study of births in the city of Rio de Janeiro, RJ, Brazil.

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.

[Maternal mortality trend in the state of Rio de Janeiro, Brazil, 2006-2018, according to the ICD-MM classification]. / Tendência da mortalidade materna no Estado do Rio de Janeiro, Brasil, entre 2006 e 2018, segundo a classificação CID-MM.

The study aimed to analyze the trend in the maternal mortality ratio (MMR) according to the ICD classification for maternal mortality (ICD-MM) classification in the state of Rio de Janeiro, Brazil, from 2006 to 2018. This was a time trend study of MMR in Rio de Janeiro according to type of death (direct or indirect) and groups of causes in the World Health Organization (WHO) ICD-MM. MMR was calculated with data from Brazilian Mortality Information System (SIM) and Brazilian Information System on Live Births (SINASC). Trends were estimated with the Joinpoint Regression Program. Of the 2,192 maternal deaths in the state, 61% were from direct causes, 34% from indirect causes, and 5% unspecified. There was a downward trend in total MMR and MMR from direct causes: -1.2% (95%CI: -2.3; -0.1) per year and -3.8% (95%CI: -4.9; -2.6) from 2006 to 2015, respectively. For direct causes, according to the ICD-MM, group 2 (hypertensive causes) predominated, but there was a decrease in eclampsia. Next came group 5 (other complications, featuring category O90 and subcategory O90.3 - peripartum cardiomyopathy) and group 1 (pregnancy with abortive outcomes). Indirect causes showed stability, and the majority belonged to category O99 and its subcategories related to cardiovascular and respiratory diseases. MMR in Rio de Janeiro showed a downward trend from 2006 to 2018, although far short of WHO recommendations and with different patterns among the causes. ICD-MM was useful for identifying major groups of causes, but it is necessary to disaggregate by subcategories to adequately elucidate the etiology of maternal death.

O objetivo foi analisar a tendência da razão de mortalidade materna (RMM) segundo a classificação CID-Mortalidade Materna (CID-MM) no Estado do Rio de Janeiro, Brasil, no período de 2006 a 2018. Foi realizado estudo de tendência temporal da RMM no Rio de Janeiro segundo tipo de óbito - direto ou indireto - e grupos de causas da classificação CID-MM, da Organização Mundial da Saúde (OMS). A RMM foi calculada com dados do Sistema de Informações sobre Mortalidade (SIM) e do Sistema de Informações sobre Nascidos Vivos (SINASC). As tendências foram estimadas pelo Joinpoint Regression Program. Dos 2.192 óbitos maternos no estado, 61% foram por causas diretas, 34% indiretas e 5% não especificadas. A tendência da RMM total e por causas diretas foi de declínio: 1,2% (IC95%: -2,3; -0,1) ao ano e 3,8% (IC95%: -4,9; -2,6) entre 2006 e 2015, respectivamente. Para causas diretas, segundo a CID-MM, o grupo 2 (causas hipertensivas) foi preponderante, mas houve declínio da eclâmpsia. Seguiram-se o grupo 5 (outras complicações, das quais se destacaram a categoria O90 e a subcategoria O90.3 - cardiomiopatia no puerpério) e o grupo 1 (gravidez que termina em aborto). As causas indiretas apresentaram estabilidade e a maioria pertencia à categoria O99 e suas subcategorias, relacionadas a doenças cardiovasculares e respiratórias. A RMM no Rio de Janeiro apresentou tendência de declínio entre 2006 e 2018, porém distante do recomendado pela OMS e com diferentes comportamentos entre as causas. A classificação CID-MM foi útil para identificar grandes grupos de causas, mas é preciso desagregar por subcategorias, para o adequado conhecimento da etiologia da morte materna.

El objetivo fue analizar la tendencia de la razón de mortalidad materna (RMM), según la clasificación CID-Mortalidad Materna (CID-MM) en el Estado de Río de Janeiro, Brasil, durante el período de 2006 a 2018. Estudio de tendencia temporal de la RMM en Río de Janeiro según el tipo de óbito -directo o indirecto- y grupos de causas de la clasificación CID-MM, de la Organización Mundial de la Salud (OMS). Se calculó la RMM con datos del Sistema de Información sobre Mortalidad (SIM) y del Sistema de Información sobre Nacidos Vivos (SINASC). Se estimaron las tendencias mediante Joinpoint Regression Program. De los 2192 óbitos maternos en el estado, un 61% fueron por causas directas, 34% indirectas y 5% no especificadas. La tendencia de la RMM total y por causas directas fue en declive: 1,2% (IC95%: -2,3; -0,1) al año y 3,8% (IC95%: -4,9; -2,6) entre 2006 y 2015, respectivamente. Para las causas directas, según la CID-MM, el grupo 2 (causas hipertensivas) fue preponderante, pero hubo declive de la eclampsia. Siguieron en el grupo 5 (otras complicaciones, de las cuales se destacaron la categoría O90 y la subcategoría O90.3 - cardiomiopatía en el puerperio) y el grupo 1 (embarazo que termina en aborto). Las causas indirectas presentaron estabilidad y la mayoría pertenecía a la categoría O99 y sus subcategorías relacionadas con enfermedades cardiovasculares y respiratorias. La RMM en Río de Janeiro presentó una tendencia decreciente entre 2006 y 2018, no obstante, dista de lo recomendado por la OMS y cuenta con diferentes comportamientos entre las causas. La clasificación CID-MM fue útil para identificar grandes grupos de causas, pero es necesario desagregar por subcategorías, para el adecuado conocimiento de la etiología de la muerte materna.

Trends in sociodemographic inequalities in prenatal care in Baixada Litorânea, a region of the state of Rio de Janeiro, Brazil, 2000-2020: an ecological study. / Tendência das desigualdades sociodemográficas no pré-natal na Baixada Litorânea do estado do Rio de Janeiro, 2000-2020: um estudo ecológico.

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.

[Unsafe abortions in the State of Rio de Janeiro, Brazil: magnitude and time trend from 2008 to 2017]. / Aborto inseguro no Estado do Rio de Janeiro, Brasil: magnitude e evolução de 2008 a 2017.

Data on unsafe abortions are scarce, and estimates based on hospitalizations have pointed to a decline in recent years. The study aimed to analyze the time trend in unsafe abortions in the State of Rio de Janeiro, Brazil, from 2008 to 2017. We used secondary data on hospitalizations in the Brazilian Unified National Health System (SUS) due to complications of abortion in childbearing-age women (CAW) 15 to 44 years of age. We applied indirect estimation with a correction factor based on national and state data. We calculated the unsafe abortion rate per CAW (UAR-CAW), ratio of unsafe abortions per live births (RUA-LB), according to age bracket. We also calculated new indicators: spontaneous abortion rate (SAR) and unspecified abortion rate (USAR) per CAW; ratio of spontaneous abortions (RSA) and ratio of unspecified abortions (RUSA) per live births, independently of age. Time trend was calculated by Joinpoint regression, calculating the annual percent change (APC) and 95% confidence intervals (95%CI). The women that most induced abortions were 20 to 24 years of age, with UAR of 8 per 1,000. Pregnancies that ended in unsafe abortion were most frequent in the 40-44-year bracket: UAR of 16 to 20 per 100 live births. Adolescents showed a reduction in UAR from 2015 to 2017 (APC = -10; 95%CI: -18.2; -1.1), while there was an increase in women 40-44 years of age from 2008 to 2017 (APC = 2.2; 95%CI 0.5 to 4.0). The other age brackets and the indicator UAR-LB showed stability. SAR (APC = -3.5; 95%CI: -5.9; -1.0), and RSA (APC = -3.8; 95%CI: -6.3; -1.2) decreased, while USAR (APC = 6.6; 95%CI: 1.7; 11.8) and RUSA (APC = 6.4; 95%CI: 1.6; 11.3) increased during the period. The magnitude and time trend of unsafe abortions in the State of Rio de Janeiro differed according to age bracket and ICD-10 code.

Dados sobre aborto inseguro são escassos e estimativas baseadas em internações apontaram decréscimo nos últimos anos. O objetivo foi analisar a evolução temporal de aborto inseguro no Estado do Rio de Janeiro, Brasil, de 2008 a 2017. Utilizamos dados secundários de internações hospitalares no Sistema Único de Saúde (SUS) por complicações de aborto, para mulheres em idade fértil de 15-44 anos. Aplicamos estimativa indireta com fator de correção baseado em dados nacionais e do estado. Calculamos: taxa de abortos inseguros por mulheres em idade fértil (TAI-MIF), razão de abortos inseguros por nascidos vivos (RAI-NV), segundo faixa etária. Adicionalmente, calculamos novos indicadores: taxa de aborto espontâneo (TAE) e não especificado (TANE) por mulheres em idade fértil; razão de aborto espontâneo (RAE) e não especificado (RANE) por nascidos vivos, independentemente da idade. A tendência temporal foi por regressão Joinpoint, calculando a mudança percentual anual (MPA) e intervalo de 95% de confiança (IC95%). As mulheres que mais induziram aborto têm de 20-24 anos: TAI de 8 por mil. Gestações terminaram em aborto inseguro mais frequentemente na faixa de 40-44 anos: RAI entre 16 e 20 por 100 nascidos vivos. As adolescentes tiveram redução da TAI entre 2015 e 2017 (MPA = -10; IC95%: -18,2; -1,1), e houve aumento para aquelas de 40-44 anos, entre 2008 e 2017(MPA = 2,2; IC95%: 0,5; 4,0). Para outras faixas e para o indicador RAI-NV houve estabilidade. A TAE (MPA = -3,5; IC95%: -5,9; -1,0), e a RAE (MPA = -3,8; IC95%: -6,3; -1,2) reduziram enquanto a TANE (MPA = 6,6; IC95%: 1,7; 11,8) e a RANE (MPA = 6,4; IC95%: 1,6; 11,3) aumentaram no período. O aborto inseguro no Estado do Rio de Janeiro mostrou magnitude e evolução temporal diferenciadas segundo faixas etárias e código da CID-10.

Fetal and infant mortality trends according to the avoidability of causes of death and maternal education.

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.

[Avoidability of fetal deaths: reflections on the Brazilian List of Avoidable Causes of Deaths through interventions by the Brazilian Unified National Health System]. / Evitabilidade de óbitos fetais: reflexões sobre a Lista Brasileira de Causas de Mortes Evitáveis por intervenção do Sistema Único de Saúde.

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.

A pesar de que la Lista Brasileña de Causas de Muerte Evitables (LBE), en su versión para niños menores de 5 años (LBE < 5), no contemple los óbitos fetales, algunos estudios la utilizaron sin o con pocas adaptaciones. Presentamos una propuesta de adaptación de la LBE para óbitos fetales (LBE-OF) y los resultados de su aplicación a óbitos fetales en el Estado de Rio de Janeiro, Brasil, en 2018, comparados con los de la LBE < 5. 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.

Brasilian List of Avidable Causes of Death that can be avoided by National Health System interventions, and its applicability for analysis of perinatal deaths in municipalities in the states of Rio de Janeiro and São Paulo, Brazil, 2011. / Aplicabilidade da Lista Brasileira de Causas de Mortes Evitáveis por intervenção do Sistema Único de Saúde, para análise de óbitos perinatais em municípios dos estados Rio de Janeiro e São Paulo, 2011.

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.

Legal abortion in Brazil: systematic review of the scientific production, 2008-2018. / Aborto legal no Brasil: revisão sistemática da produção científica, 2008-2018.

Previous reviews on the subject of abortion in Brazil have estimated one million procedures per year but did not address legal abortion. This systematic review sought to update knowledge regarding legal abortion in terms of service and women's profile, student and doctor knowledge, situations of anencephaly and severe malformations. We searched MEDLINE and LILACS for articles published in all languages between 2008 and 2018. Article quality was assessed using the Joanna Briggs Institute instruments. Search, selection, quality assessment and data extraction were carried out independently by two researchers. We selected 20 articles, 11 on the knowledge and opinion of medical professionals (4 articles) and students (7 articles) revealing a less-than-ideal level of knowledge and a high degree of objection of conscience. Six studies on women who use legal abortion services found that they are young, single and that the main demand was for pregnancy resulting from rape. When women were younger and single and when the aggressor was someone close to them, there were delays in seeking care. Three studies on severe malformation found around 40% of court authorizations. In cases for which no authorization was given, the evolution of pregnancies was complicated and deliveries were done through cesarean sections. Only one article addressed legal abortion services, showing that 37 of the 68 that had been registered were active, lack of services in seven states and concentration in capitals. Knowledge regarding legal abortion is still scarce, the demand for the procedure is repressed and medical training is deficient with regard to this subject.

Revisões anteriores sobre o aborto no Brasil estimaram um milhão de procedimentos anuais, porém, não abordaram o aborto legal. O objetivo desta revisão sistemática foi atualizar o conhecimento sobre o aborto legal, quanto ao perfil dos serviços, das mulheres atendidas, conhecimento de estudantes e médicos, situação de anencefalia e malformações graves. A busca de artigos foi via MEDLINE e LILACS, de 2008 a 2018, sem restrição de idiomas. A qualidade dos artigos foi avaliada com instrumentos do Joanna Briggs Institute. Busca, seleção, avaliação de qualidade e extração de dados foram feitas independentemente por duas pesquisadoras. Selecionaram-se 20 artigos, 11 sobre conhecimento e opinião de profissionais médicos (4 artigos) e estudantes de Medicina (7 artigos), revelando conhecimento aquém do ideal sobre o aborto legal e objeção de consciência elevada. Seis estudos sobre as mulheres atendidas identificaram que elas são jovens, solteiras e a principal demanda foi a gravidez decorrente de estupro. A demora em procurar atendimento ocorreu dentre as mais jovens, solteiras e quando o agressor era alguém próximo. Três estudos sobre malformações graves mostraram autorização judicial em torno de 40%. Nos casos sem autorização, a evolução da gravidez foi complicada e o parto foi cesáreo. Apenas um artigo abordou os serviços de aborto legal, apontando 37 dos 68 cadastrados em atividade, inexistência em sete estados e concentração nas capitais. O conhecimento sobre o aborto legal ainda é escasso, a demanda do procedimento é reprimida e a formação médica é deficiente no tema.

Se seleccionaron 20 artículos, 11 sobre conocimiento y opinión de profesionales médicos (4 artículos) y estudiantes de Medicina (7 artículos), revelando conocimiento inferior al ideal sobre el aborto legal y la objeción de conciencia. Seis estudios sobre las mujeres atendidas identificaron que se trata de jóvenes, solteras y la principal demanda fue el embarazo ocasionado por una violación. La tardanza en buscar atención se produjo entre las más jóvenes, solteras y cuando el agresor era alguien cercano. Tres estudios sobre malformaciones graves mostraron una autorización judicial en torno a un 40%. En los casos sin autorización, la evolución del embarazo fue complicada y el parto fue por cesárea. Solamente un artículo abordó los servicios de aborto legal, apuntando 37 de los 68 registrados en actividad, inexistencia en siete estados y concentración en las capitales. El conocimiento sobre el aborto legal todavía es escaso, la demanda de la intervención está reprimida y la formación médica es deficiente en el tema.

Unsafe abortion in Brazil: a systematic review of the scientific production, 2008-2018. / Aborto inseguro no Brasil: revisão sistemática da produção científica, 2008-2018.

This study sought to update knowledge on unsafe abortion in Brazil. We carried out a systematic review with study search and selection on MEDLINE and LILACS, with no language restriction, from 2008 to 2018. We evaluated article quality using the Joanna Briggs Institute instruments. We evaluated 50 articles. The prevalence of induced abortion in Brazil was estimated by a direct method to be 15% in 2010 and 13% in 2016. Higher prevalences were observed in more socially vulnerable populations. There was a decrease in the ratio of induced abortions by 1,000 women of reproductive age in the period 1995-2013, reaching 16 per 1,000 in 2013. Half of all women reported using medications for terminating pregnancies and the number of hospital admissions due to complications from abortion, especially severe complications, decreased from 1992 to 2009. Maternal morbimortality from abortion had a reduced frequency but reached high values in specific contexts. It is likely that maternal deaths from abortion are under-reported. Common mental disorders during pregnancy and postpartum depression were more frequent among women who unsuccessfully attempted to induce an abortion. Findings indicate that abortion is frequently used in Brazil, especially in less-developed regions and by more socially-vulnerable women. Access to safer methods probably contributed to the reduction in hospitalizations due to complications and to the reduction in morbimortality from abortion. However, half of all women still resort to other methods and the number of admissions due to complications from abortion is still high.

O objetivo deste estudo é atualizar o conhecimento sobre o aborto inseguro no país. Foi realizada uma revisão sistemática com busca e seleção de estudos via MEDLINE e LILACS, sem restrição de idiomas, no período 2008 a 2018, com avaliação da qualidade dos artigos por meio dos instrumentos elaborados pelo Instituto Joanna Briggs. Foram avaliados 50 artigos. A prevalência de aborto induzido no Brasil foi estimada por método direto em 15% no ano de 2010 e 13% no ano de 2016. Prevalências mais elevadas foram observadas em populações socialmente mais vulneráveis. A razão de aborto induzido por 1.000 mulheres em idade fértil reduziu no período 1995-2013, sendo de 16 por 1.000 em 2013. Metade das mulheres referiu a utilização de medicamentos para a interrupção da gestação e o número de internações por complicações do aborto, principalmente complicações graves, reduziu no período 1992-2009. A morbimortalidade materna por aborto apresentou frequência reduzida, mas alcançou valores elevados em contextos específicos. Há um provável sub-registro de óbitos maternos por aborto. Transtornos mentais comuns na gestação e depressão pós-parto foram mais frequentes em mulheres que tentaram induzir um aborto sem sucesso. Os resultados encontrados indicam que o aborto é usado com frequência no Brasil, principalmente nas regiões menos desenvolvidas e por mulheres socialmente mais vulneráveis. O acesso a métodos mais seguros provavelmente contribuiu para a redução de internações por complicações e para a redução da morbimortalidade por aborto. Entretanto, metade das mulheres ainda recorre a outros métodos e o número de internações por complicações do aborto é ainda elevado.
