Abstract Although variation between observers in the assessment of the Apgar score, it remains a useful indicator of the general conditions of the newborn. This is a cross-sectional study based on population of live births in Brazil in 1999 and biennium 2018-2019. All declarations of live births (DNV) obtained from the Live Births System database were accessed. Frequencies were compared between groups using Pearson’s chi-square test and multivariate logistic regression analysis was performed. A statistical significance level of 0.05 was considered. We included 9.050.521 DNVs in our research. We found that 2,1% of newborns had 5th minute Apgar < 7 in 1999 compared with 0,9% in 2018-2019. Multivariate analysis shows that twins and teenage pregnancy are no longer risk factors. Among risk factors, we observed an increase in prematurity, low birth weight and congenital anomalies. An improvement in maternal markers was observed, especially increase in the number of prenatal consultations and schooling. Such findings demonstrate the importance access and adequate prenatal care and improved socioeconomic conditions as effective strategy to reduce neonatal morbidity and mortality.

Resumo Apesar da variação entre observadores na avaliação do escore de Apgar, ele permanece um indicador útil das condições gerais do recém-nascido. O presente trabalho é um estudo de corte transversal baseado na população de nascidos vivos no Brasil no ano de 1999 e no biênio 2018-2019. Foram avaliadas todas as declarações de nascidos vivos (DNV) obtidas a partir do banco de dados do Sistema de Informações sobre Nascidos Vivos. As frequências foram comparadas entre os grupos por meio do teste qui-quadrado de Pearson e foi realizada análise de regressão logística multivariada. Adotou-se nível de significância estatística de 0,05. Foram analisadas 9.050.521 DNVs em nossa pesquisa. Constatamos que 2,1% dos recém-nascidos tiveram Apgar de 5º minuto < 7 em 1999, em comparação com 0,9% em 2018-2019. A análise multivariada indicou que gemelidade e gravidez na adolescência deixaram de ser fatores de risco para Apgar de 5º minuto < 7. Entre os fatores de risco, nota-se aumento da prematuridade, baixo peso ao nascer e anomalias congênitas. Observou-se melhoria de marcadores maternos, em especial o aumento do número de consultas pré-natais e escolaridade. Tais achados mostram a importância de acesso e seguimento pré-natal adequado e investimento em melhores condições socioeconômicas como estratégia eficaz para redução de morbimortalidade neonatal.

SUMMARY OBJECTIVE: This study aimed to assess live birth frequency and age-specific fertility rates (ASFR) in the period 1996–2018 and the number of pregnancies at <14 years old in the period 2012–2018. METHODS: This was a cross-sectional study conducted by search on Live Births Data System (SINASC/DATASUS) database. RESULTS: There was a variation in ASFR in Brazil of 0.78‰ in 1996 to 0.87‰ in 2018 (+11.5%). In the north region, it increased from 1.28‰ to 1.66‰ in 2018. In the northeast region, it increased from 0.72‰ to 1.66‰ (+131%) in 1996–2011, but decreased to 1.31‰ in 2018 (-21% in relation to 2011). When comparing 1996 and 2018, in the southeast region, there was a 22% decrease; in the south region, it was 48.2%; and in the Center-West region, it was 34%; but in the north region, there was a 29.7% increase, and in the northeast region, it was 81.9%. When adding girls who became pregnant aged 13 years and gave birth at 14, there was a threefold increase in the rate. CONCLUSIONS: The increase of pregnancies in <14 years old in less developed regions of Brazil shows an association with socioeconomic factors and reveals the severe problem of rape of vulnerable persons in the country.

ABSTRACT Introduction: In 2013, the World Health Organization (WHO) reported that 1.9 million pregnant women were infected with syphilis worldwide, of which 66.5% had adverse fetal effects in cases of untreated syphilis. Congenital syphilis contributes significantly to infant mortality, accounting for 305,000 perinatal deaths worldwide annually. Aim: To estimate the prevalence of syphilis in parturients, the incidence of congenital syphilis and the vertical transmission rate. Material and methods: a cross-sectional study with data collected from 2041 parturients who had undergone treatment between 2012 and 2014 in the maternity section of the Pedro Ernesto Hospital of the State University of Rio de Janeiro, in the metropolitan area of Rio de Janeiro. The inclusion criterion was positive VDRL and treponemal test in a hospital environment. Results: the prevalence of syphilis in pregnant women was 4.1% in 2012, 3.1% in 2013 and 5% in 2014, with official reporting of 15.6%, 25.0% and 48.1%, respectively. The incidence of congenital syphilis (CS) was 22/1,000 in live births (LB) in 2012; 17/1,000 LB in 2013 and 44.8/1,000 LB in 2014. CS underreporting during the period was 6.7%. Vertical transmission occurred in 65.8% of infants from infected mothers. It was concluded that, in 34.6% of the CS cases, maternal VDRL titers were = 1/4. Conclusion: Results demonstrate the magnitude of the disease, fragility of the reporting system in the assessment of the actual prevalence, impact on perinatal outcomes, and they are a warning about the real situation of syphilis, which is still underestimated in the State.
