ABSTRACT

Introducción. La mortalidad de los recién nacidos de muy bajo peso de nacimiento (RNMBPN) se ha mantenido en ~26 % en los últimos 16 años en la Red Neonatal NEOCOSUR. Objetivo. Determinar la causa de muerte de los RNMBPN y su temporalidad en el período 20072016 en la Red Neonatal NEOCOSUR. Población y métodos. Estudio observacional de cohorte multicéntrica; análisis retrospectivo de datos obtenidos prospectivamente. Se incluyeron recién nacidos entre 24 y 31+6 semanas de edad gestacional y peso de nacimiento de 500-1500 g, en 26 centros de la Red Neonatal NEOCOSUR. Las causas de muerte se analizaron según ocurriera en sala de partos (SP) o durante la estadía en la unidad de cuidados intensivos neonatales (UCIN). La edad posnatal de muerte se determinó a través de análisis de Kaplan-Meier. Resultados. Se incluyeron un total de 11.753 RNMBPN con una mortalidad global del 25,6 %. Las causas de muerte predominantes en SP fueron malformaciones congénitas (43,3 %), enfermedades respiratorias (14,3 %) y prematuridad (11,4 %). Las causas de muerte predominantes en UCIN fueron las respiratorias (24,2 %) e infecciosas (24,1 %). La edad promedio de muerte fue de 10,2 días y mediana de 4 días. El 10,2 % de las muertes ocurrieron en SP; el 21,5 %, durante el primer día; el 52 % ocurrió en los primeros 4 días y el 63,8 %, durante la primera semana de vida. Conclusiones. Se encuentran importantes diferencias en las causas de muerte de RNMBPN según ocurra en SP o en UCIN. Las infecciosas y respiratorias son las más relevantes luego del ingreso a la unidad de cuidados intensivos.


Introduction. Mortality in very low birth weight infants (VLBWIs) has remained at ~26% in the past 16 years in the NEOCOSUR Neonatal Network. Objective. To determine the cause of death of VLBWIs and its temporality in the 2007-2016 period in the NEOCOSUR Neonatal Network. Population and methods. Observational, multicenter cohort study; retrospective analysis of data collected prospectively. Newborn infants born between 24 and 31+6 weeks of gestation age with a birth weight between 500 and 1500 g in the 26 sites of the NEOCOSUR Neonatal Network were included. The causes of death were analyzed depending on whether they occurred in the delivery room (DR) or in the neonatal intensive care unit (NICU). The postnatal age at time of death was determined using the KaplanMeier test. Results. A total of 11 753 VLBWIs were included; overall mortality was 25.6%. The prevailing causes of death in the DR were congenital malformations (43.3%), respiratory diseases (14.3%), and prematurity (11.4%). The prevailing causes of death in the NICU were respiratory diseases (24.2%) and infections (24.1%). The average and median age at death were 10.2 and 4 days, respectively. Also, 10.2% of deaths occurred in the DR; 21.5% on day 1, 52% in the first 4 days, and 63.8% in the first week of life. Conclusions. Important differences were observed in the causes of death of VLBWIs depending on their occurrence in the DR or the NICU. Infectious and respiratory conditions were the most relevant factors following admission to the NICU.

ABSTRACT

INTRODUCCIÓN: La violencia en la gestante está asociada a muchos factores del recién nacido, pero esto casi no se ha reportado en la altura geográfica. OBJETIVO: Determinar si existe asociación entre el maltrato en la gestante adolescente y su efecto en el peso del recién nacido en la altura geográfica peruana. MÉTODO: Estudio de cohorte retrospectiva. Se tomó la información de 855 gestantes. La variable exposición fue que hubieran sufrido violencia, lo cual se asoció al peso y otros datos del recién nacido en la ciudad de Huancayo, Perú. RESULTADOS: Según el análisis multivariado, hubo más riesgo de que el niño tuviera un peso inadecuado cuando hubo violencia física (riesgo relativo ajustado [RRa]: 1,42; intervalo de confianza del 95% [IC95%]: 1,01-2,00; p = 0,045), cuando se tuvo un parto pretérmino según Capurro (RRa: 4,90; IC95%: 2,85-8,45; p < 0,001), cuando hubo complicaciones en el parto (RRa: 2,11; IC95%: 1,25-3,61; p = 0,006) y si el abuso inició en el primer trimestre (RRa: 14,74; IC95%: 4,70-46,27; p < 0,001), el segundo (RRa: 18,72; IC95%: 5,78-60,63; p < 0,001) o el tercero (RRa: 18,87; IC95%: 4,71-75,60; p < 0,001). CONCLUSIONES: Existe asociación entre sufrir violencia física durante la gestación y el bajo peso al nacer, y también se encontró asociación con otras variables.


INTRODUCTION: Violence in the pregnant woman is associated with many newborn factors, but this has hardly been reported in the geographical altitude. OBJECTIVE: To determine whether there is an association between adolescent pregnancy abuse and its effect on newborn birth weight in high altitude Peru. METHOD: Retrospective cohort study. Information was taken from 855 pregnant women. The exposure variable was whether they had suffered gender-based violence, the exposure variable was that they had suffered violence, which was associated with the weight and other data of the newborn in Huancayo city, Peru. RESULTS: In the multivariatee analysis it was found that there was a higher risk of the child having an inadequate weight when there was physical violence (adjusted relative risk [RRa]: 1.42; 95% confidence interval [95% CI]: 1.01-2.00; p = 0.045), when there was a preterm birth according to Capurro (RRa: 4.90; 95% CI: 2.85-8.45; p < 0.001), when there were complications in childbirth (RRa: 2.11; 95% CI: 1.25-3.61; p = 0.006) and if the abuse started in the first trimester (RRa: 14.74; 95% CI: 4.70-46.27; p < 0.001), second (RRa: 18.72; 95% CI: 5.78-60.63; p < 0.001) or third (RRa: 18.87; 95% CI: 4.71-75.60; p < 0.001). CONCLUSIONS: There is an association between suffering physical violence during gestation and low birth weight, and association was also found with other variables.

ABSTRACT

Abstract Objectives: to assess the effects of vitamin D supplementation during pregnancy on the outcomes of vitamin D concentration in newborns, length at birth, overall health (Apgar), birth weight and maternal vitamin D concentration after childbirth. Methods: this research was conducted in the electronic databases of MEDLINE, LILACS, EMBASE and Cochrane Library until December 2020, using the terms "vitamin D", "pregnancy", "vitamin D deficiency", "infant", "newborn" and their synonyms. Randomized controlled trials were searched by evaluating the effects of maternal vitamin D supplementation in neonates. The data was analyzed on RevMan 5.4 software and the quality of evidence on GRADE. Results: the newborn's overall health condition was presented as Apgar, with a mean difference (MD) of 0.15 (CI95%=0.06-0.25; p=0.002; I2=0%, two studies, 648 participants, moderate quality evidence) at the first minute and 0.11 (CI95%=0.04-0.17; p=0.001; I2=0%, two studies, 648 participants, moderate quality evidence) at the fifth minute. Significant effects were also presented at the length at birth considering any supplemented dose (MD=0.19; CI95%=0.08-0.30; p=0.0010; I2=0%, 1452 participants, low quality evidence) and birth weight in doses higher than 4000IU/day (MD=257.05 (CI95%=137.81-376.29; p<0.0001; I2=14%, 176 participants, moderate quality evidence). Conclusion: vitamin D supplementation during pregnancy improves serum 25 (OH) D concentration and suggests positive effects on overall health condition, length at birth and birth weight. PROSPERO CRD42017073292.

Métodos: a pesquisa foi conduzida nas bases de dados eletrônicas MEDLINE, LILACS, EMBASE e Cochrane Library até dezembro de 2020, utilizando os termos "vitamin D", "pregnancy", "vitamin D deficiency", "infant", "newborn" e seus sinônimos. Pesquisou-se por ensaios clínicos randomizados avaliando os efeitos da suplementação materna de vitamina D no neonato. Os dados foram analisados pelo software RevMan 5.4 e a avaliação da qualidade das evidências pelo GRADE. Resultados: o estado geral de saúde do recém-nascido foi apresentado como Apgar, com uma diferença de média (DM) de 0,15 (IC95%=0,06-0,25; p=0,002; I2=0%, dois estudos, 648 participantes, evidência de qualidade moderada) para o teste no primeiro minuto e 0,11 (IC95%=0,04-0,17; p=0,001; I2=0%, dois estudos, 648 participantes, evidência de qualidade moderada) para quinto minuto. Efeitos significativos também foram apresentados para o comprimento ao nascer em qualquer dose suplementada (DM=0,19 (IC95%=0,08-0,30; p=0,0010; I2=0%, 1452 participantes, evidência de baixa qualidade) e peso ao nascer em doses maiores que 4000UI/dia (DM=257,05 (IC95%=137,81-376,29; p<0,0001; I2=14%, 176 participantes, evidência de qualidade moderada). Conclusão: a suplementação de vitamina D durante a gravidez melhora a concentração sérica de 25 (OH)D e sugere apresentar efeitos positivos no estado geral de saúde, comprimento ao nascer e peso ao nascer.

ABSTRACT

Objetivou-se analisar o perfil epidemiológico e as causas da mortalidade neonatal e infantil, em uma Regional de Saúde, de janeiro/2018 a agosto/2020. Trata-se de pesquisa exploratória, descritiva, transversal, retrospectivo, com abordagem quantitativa. A coleta de dados ocorreu em agosto de 2020, por meio de questionário elaborado pelas pesquisadoras, com base nas declarações de óbito disponibilizadas no Sistema de Informações de Mortalidade. O instrumento abordou as variáveis, sexo, raça, cor, idade da criança, idade materna, escolaridade materna, via de parto, idade gestacional, peso ao nascer, causa do óbito. Os dados foram submetidos à análise estatística descritiva e distribuição de frequência, por meio do Statistical Package for the Social Sciences (SPSS), versão 25.0. Constatou-se o predomínio de óbitos no sexo masculino (56,5%), de raça branca (87,8%), com equivalência entre extremo baixo peso e adequado (31,3%), com a principal causa de óbito por septicemia (13,9%). Quanto aos dados maternos, prevaleceram idade entre 21 e 30 anos de idade (45,2%) com gestação única (85,21%) e parto cesariano (65,2 %). Desses, 47,87% ocorreram no ano de 2018. Analisar os aspectos da mortalidade neonatal e infantil possibilita o planejamento e a readequação de ações no atendimento à saúde da criança, durante o período mais vulnerável e mais crítico dela, contribuindo, assim, para redução do número de óbitos.


This study analyzed the epidemiological profile and the causes of neonatal and infant mortality in a Health Regional Area between January 2018 and August 2020. This is an exploratory, descriptive, cross-sectional, retrospective study with a quantitative approach. Data collection took place during August 2020 through a questionnaire prepared by the researchers, based on the death certificates available in the Mortality Information System. The instrument included the variables of sex, race, color, child's age, mother's age, maternal education, childbirth mode, gestational age, birth weight, cause of death. The data were submitted to descriptive statistical analysis and frequency distribution using the Statistical Package for the Social Sciences (SPSS) version 25.0. There was a predominance of deaths among boys (56.5%), Caucasian (87.8%), with equivalence between extreme low and adequate weight (31.3%), with the main cause of death being septicemia (13.9%). As for maternal data, age between 21 to 30 years old (45.2%) prevailed, and 85.21% had a single pregnancy, with C-section childbirth (65.2%). From these, 47.87% occurred in 2018. It can be concluded that analyzing the aspects of neonatal and child mortality enables the planning and adjustment of actions in child health care during its most vulnerable and most critical period, thus contributing to reducing the number of deaths.

ABSTRACT

Abstract Objectives: to compare the intrauterine and postnatal growth of preterm infants according to the Intergrowth-21st and Fenton curves. Methods: study carried out in a maternity hospital, reference in high-risk pregnancy, with preterm infants born in 2018 who were hospitalized in the neonatal units of the institution. Preterm newborns weighed at least twice after birth were included in the sample and those that were syndromic, malformed or presented fluid retention were excluded. Proportions and means were compared using Pearson's chi-square and Student's t tests for paired samples, respectively. The McNemar test was used to compare categorical variables and the Kappa test to verify the degree of agreement between birth weight classifications obtained by the curves. Results: one hundred and fifty three infants with a median gestational age of 34.4 weeks were included. The incidences of the categories of nutritional status at birth did not differ between the curves. There was perfect agreement between the curves, except when newborns born under 33 weeks of gestational age were evaluated, in which case the agreement was substantial. About 21% of the babies classified as small for gestational age (SGA) by Intergrowth-21st were adequate for gestational age (AGA) according to Fenton and, on average, 20% of cases that had postnatal growth restriction (PNGR) according to Fenton standards were categorized as adequate weight by Intergrowth-21st. Postnatal weight classifications obtained by the evaluated curves had perfect agreement. Conclusions: the differences in theclassifications found between the charts reveal the importance of choosing the growth curve for monitoring preterm infants since behaviors based on their diagnoses can impact the life of this population.


Resumo Objetivos: comparar o crescimento intrauterino e pós-natal de prematuros segundo as curvas de Intergrowth-21st e Fenton. Métodos: estudo realizado em uma maternidade de referência em gestação de alto risco com prematuros nascidos em 2018 que ficaram internados nas unidades neonatais da instituição. Foram incluídos os pré-termos pesados em pelo menos dois momentos após o nascimento e excluídos aqueles sindrômicos, malformados ou com retenção hídrica. As proporções e médias foram comparadas a partir dos testes qui-quadrado de Pearson e t de student para amostras emparelhadas, respectivamente. Já o teste de McNemar foi utilizado para comparar as variáveis categóricas e teste Kappa para verificar o grau de concordância entre as classificações de peso ao nascer obtidos pelas curvas. Resultados: foram incluídos 153 lactentes com idade gestacional mediana de 34,4 semanas. As incidências das categorias de estado nutricional ao nascer não diferiram entre as curvas. Houve concordância perfeita entre as mesmas, exceto quando se avaliou os nascidos com menos de 33 semanas, onde a concordância foi substancial. Cerca de 21% dos bebês classificados como pequenos para a idade gestacional (PIG) por Intergrowth-21st foram adequados para idade gestacional (AIG) segundo Fenton e, em média, 20% dos casos que tiveram restrição de crescimento pós-natal (RCPN) de acordo aos padrões de Fenton foram categorizados com peso adequado por Intergrowth-21st. As classificações de peso pós-natal obtidas pelas curvas avaliadas tiveram concordância perfeita. Conclusões: as diferenças de classificação encontradas revelam a importância da escolha da curva de crescimento para monitorização de prematuros visto que, condutas baseadas em seus diagnósticos, podem impactar na vida dessa população.

ABSTRACT

RESUMEN Introducción: El ácido úrico es el producto final del ciclo de las purinas y es fundamental como marcador de enfermedad renal, la gota y la preeclampsia. Este biomarcador ejerce efectos potenciales en la placenta y el feto de la gestante con drepanocitosis. Objetivo: Describir los efectos potenciales que produce el ácido úrico en las gestantes con drepanocitosis. Métodos: Se revisó literatura en inglés y en español, a través del sitio web PubMed y el motor de búsqueda Google académico, en artículos publicados en los últimos cinco años. Se utilizaron como términos de búsqueda: preeclampsia, ácido úrico y riesgos en las embarazadas con drepanocitosis. Se analizaron los aspectos más relevantes del tema en la bibliografía revisada. Análisis y síntesis de la información: El incremento del ácido úrico añadido a la vasoclusión, la hipoxia y la necrosis tisular a nivel de la placenta son mecanismos invocados en el desarrollo de la preeclampsia y los índices de partos prematuros que presentan. Es de destacar que no tiene una trayectoria uniforme en todas las pacientes, sobre todo se observa una mejor evolución (con menor presencia de estas complicaciones) en aquellas pacientes que muestran genotipo, niveles de hemoglobina fetal y haplotipo de la hemoglobina S más favorable. Conclusiones: El ácido úrico constituye un biomarcador útil y de alarma en el diagnóstico de la preeclampsia, una de las peores complicaciones tanto para la vida materna como para su descendencia, al ser la gestante con drepanocitosis una paciente de muy alto riesgo de parto pretérmino, prematuridad, bajo peso al nacer, nacidos muertos e infarto placentario.


ABSTRACT Introduction: Uric acid is the end product of the purine cycle and is essential as a marker of kidney disease, gout and pre-eclampsia. This biomarker has potential effects on the placenta and fetus of a pregnant woman with sickle cell disease. Objective: To describe the potential effects of uric acid in pregnant women with sickle cell disease. Methods: Literature in English and Spanish was reviewed, through the PubMed website and the academic search engine Google, in articles published in the last five years. The search terms were: pre-eclampsia, uric acid and risks in pregnant women with sickle cell disease. The most relevant aspects of the subject were analyzed in the reviewed bibliography. Analysis and synthesis of information: The increase in uric acid added to vasoocclusion, hypoxia and tissue necrosis at the level of the placenta are mechanisms invoked in the development of pre-eclampsia and the rates of premature births they present. It is noteworthy that it does not have a uniform trajectory in all patients, especially a better evolution is observed, with less presence of these complications in those patients who show a more favorable genotype, fetal hemoglobin levels and hemoglobin S haplotype. Conclusions: Uric acid constitutes a useful and alarm biomarker in the diagnosis of pre-eclampsia, one of the worst complications both for maternal life and for her offspring, as the pregnant woman with sickle cell disease is a patient at a very high risk of preterm delivery. prematurity, low birth weight, stillbirths and placental infarction.

ABSTRACT

ABSTRACT Objective: Gestational diabetes mellitus (GDM) causes maternal and infant morbidity. Periodontitis is associated with adverse pregnancy outcomes. The aim of this study was to evaluate periodontal status, prematurity and associated factors in pregnant women with and without GDM. Subjects and methods: This observational cross-sectional study included 80 pregnant women with GDM (G1 = 40) and without GDM (G2 = 40). Demographic and socioeconomic status, systemic and periodontal health condition, prematurity and newborns' birth weight were analyzed. For bivariate analysis, Mann-Whitney U-test, t test and Chi-squared test were used. Binary logistic regression analyzed independent variables for periodontitis and prematurity (p < 0.05). Results: Patients from G1 presented lower socioeconomic status, higher weight and body mass index (BMI). Prematurity (G1 = 27.5%; G2 = 2.5%; p < 0.05) and severe periodontitis percentages (G1 = 22.5%; G2 = 0; p = 0.001) were higher in G1 than in G2. Logistic regression analysis showed that household monthly income (OR = 0.65; 95% CI 0.48-0.86; p = 0.003) and maternal BMI (adjusted OR = 1.12; 95% CI 1.01-1.25; p = 0.028) were significant predictors of periodontitis during the third trimester of pregnancy. Presence of GDM remained in the final logistic model related to prematurity (adjusted OR = 14.79; 95% CI 1.80-121.13; p = 0.012). Conclusions: Pregnant women with GDM presented higher severity of periodontitis, lower socioeconomic status, higher overweight/obesity and a 10-fold higher risk of prematurity. Socioeconomic-cultural status and BMI were significant predictors for periodontitis, and GDM was a predictor to prematurity.

ABSTRACT

Introdução: A mortalidade fetal é um dos resultados perinatais adversos mais comuns em todo o mundo, constituindo-se indicador relevante da atenção ao pré-natal e parto. Contudo, a compreensão sobre os aspectos relacionados a essas mortes permanece insuficiente para subsidiar as estratégias de prevenção. Objetivo: (i) analisar a evolução temporal das Taxas de Mortalidade Fetal (TMF) e a contribuição da investigação na melhoria da definição da causa básica do óbito fetal no Município de São Paulo (MSP), segundo local de emissão da declaração de óbito; (ii) analisar a distribuição dos óbitos fetais por peso ao nascer, tipo de óbito, tendência da TMF e as causas de morte evitáveis segundo clusters de vulnerabilidade social no Município de São Paulo, 2007-2017; (iii) estimar o risco de óbito fetal em fenótipos de vulnerabilidade biológica baseados na duração da gestação, peso ao nascer e crescimento intrauterino no Município de São Paulo, 2017-2019. Métodos: a tese compreende três manuscritos: (i) a regressão linear generalizada de Prais-Winsten foi empregada na análise de séries temporais. O teste de McNemar avaliou a mudança das causas básicas após a investigação dos óbitos fetais entre 2012-2014. (ii) Utilizou-se o método k-means para criação de clusters de distritos com base no Índice Paulista de Vulnerabilidade Social. A regressão linear generalizada de Prais-Winsten foi empregada na análise de séries temporais. A Lista Brasileira de Causas de Mortes Evitáveis foi adaptada para o estudo dos óbitos fetais. (iii) Os fetos Pequenos para a Idade Gestacional (PIG), Grandes para a Idade Gestacional (GIG) e Adequados para a Idade Gestacional (AIG) foram identificados a partir dos parâmetros do INTERGROWTH-21st. Definiu-se pré-termo (PT) como ≤36 semanas, não PT como ≥37semanas de gestação, baixo peso ao nascer (BPN) como <2.500g e não BPN como ≥2.500g. Os Riscos Relativos (RR) foram estimados pela regressão de Poisson com variância robusta. Resultados: no primeiro artigo, constatou-se tendência de aumento (1,5% ao ano) da TMF dos óbitos com <2.500g e de redução anual de -1,3% naqueles com ≥2.500g. Entre 2012-2014, cerca de 90% dos óbitos com ≥2.500g foram investigados e 15% desses apresentaram redefinição da causa básica de morte, sobretudo naqueles cuja declaração de óbito foi emitida pelos serviços de verificação de óbito (SVO) (17%). Após a investigação a morte fetal não especificada (P95) representou 1/4 das causas de óbito. No segundo artigo, identificou-se predominância dos óbitos fetais anteparto (70%). Houve aumento da TMF e das causas de óbito evitáveis com o crescimento da vulnerabilidade social do centro para a periferia da cidade. O cluster de maior vulnerabilidade apresentou TMF 69% maior que o cluster de menor vulnerabilidade. A TMF ≥2.500g foi decrescente nos clusters de maior vulnerabilidade. Na área de maior vulnerabilidade, as causas de morte mal definidas representaram 75% dos óbitos. No terceiro artigo, o total de gestações em risco foi de 451.952. Destas, 2.321 resultaram em óbitos fetais. Os fenótipos associados simultaneamente ao baixo peso ao nascer e prematuridade apresentaram maior risco de morte, sendo este 49,9 (IC95%: 44,06-56,54) vezes maior para AIG, 144,9 (IC95%: 127,39-164,88) vezes maior para PIG e 245,3 (IC95%: 192,41-312,72) vezes maior para GIG, quando comparados com AIG, não baixo peso ao nascer e não pré-termo. Conclusão: os óbitos fetais de ≥2.500g, alvo das ações de vigilância, apresentaram tendência de redução, sobretudo nos clusters de maior vulnerabilidade social. Tal fato pode sugerir melhoria da atenção ao pré-natal no MSP, especialmente nas áreas de média e alta vulnerabilidade. Apesar da investigação do óbito ter contribuído para melhoria da redefinição da causa básica, especialmente naquelas atestadas pelo SVO, as mudanças foram insuficientes para indicação de causas que melhor retratassem os processos fisiopatológicos que resultaram nos óbitos fetais. As taxas de mortalidade fetal e de causas evitáveis aumentaram com o aumento da vulnerabilidade social, ou seja, no sentido do centro para a periferia da cidade. A despeito dos fenótipos de vulnerabilidade biológica, estes mostraram-se indicadores úteis de vigilância perinatal que permitem identificar as gestações com maior risco de morte fetal.


Background: Fetal mortality is one of the most common adverse perinatal outcomes worldwide, constituting a relevant indicator of prenatal care and childbirth. However, the understanding of aspects related to these deaths remains insufficient to support prevention strategies. Goals: (i) to analyze the temporal evolution of the Stillbirth Rates (SBR) and the contribution of the investigation to improve the definition of the underlying cause of stillbirth in the Municipality of São Paulo (MSP), according to the place of issuance of the declaration of death; (ii) analyze the distribution of stillbirth by birth weight, type of death, SBR trend and preventable causes of death according to social vulnerability clusters in the Municipality of São Paulo, 2007-2017; (iii) estimate the risk of stillbirth in biological vulnerability phenotypes based on gestation length, birth weigh and intrauterine growth in the Municipality of São Paulo, 2017-2019. Methods: The thesis comprises three manuscripts: (i) Generalized linear Prais-Winsten regression was used in the analysis of time series. McNemar's test evaluated the change in underlying causes after the investigation of stillbirths between 2012-2014. (ii) The k-means method was used to create clusters of districts based on the São Paulo Social Vulnerability Index. Generalized linear Prais-Winsten regression was used in the analysis of time series. The Brazilian List of Preventable Deaths Causes was adapted for the study of stillbirths. (iii) Small for Gestational Age (SGA), Large for Gestational Age (LGA), and Adequate for Gestational Age (AGA) fetuses were identified from the INTERGROWTH-21st parameters. Preterm (PT) was defined as ≤36 weeks, non-PT as ≥37 weeks of gestation, low birth weight (LBW) as <2,500g, and non-LBW as ≥2,500g. Relative Risks (RR) were estimated by Poisson regression with robust variance. Results: In the first article, there was a trend towards an increase (1.5% per year) in the SBR of deaths weighing <2,500g and an annual reduction of -1.3% in those weighing ≥2,500g. Between 2012-2014, about 90% of deaths weighing ≥2,500g were investigated and 15% of these had redefinition of the underlying cause of death, especially those whose death certificate was issued by the death verification services (DVS) (17%). After investigation, unspecified fetal death (P95) represented 1/4 of the causes of death. The second article identified a predominance of antepartum stillbirths (70%). There was an increase in TMF and preventable causes of death with the growth of social vulnerability from the center to the outskirts of the city. The cluster with the highest vulnerability had an SBR 69% higher than the cluster with the lowest vulnerability. The SBR ≥2,500g was decreasing in the most vulnerable clusters. In the most vulnerable area, ill-defined causes of death accounted for 75% of deaths. In the third article, the total number of pregnancies at risk was 451,952. Of these, 2,321 resulted in fetal death. The Phenotypes associated simultaneously with low birth weight and prematurity had a higher risk of death, which was 49.9 (95%CI: 44.06-56.54) times higher for AGA, 144.9 (95%CI: 127.39-164.88) times greater for SGA and 245.3 (95%CI: 192.41-312.72) times greater for LGA, when compared to AGA, not low birth weight and not preterm. Conclusion: stillbirths weighing ≥2,500g, targeted by surveillance actions, showed a tendency to decrease, especially in clusters with greater social vulnerability. This fact may suggest an improvement in prenatal care in the MSP, especially in areas of medium and high vulnerability. Although the investigation of death contributed to an improvement in the redefinition of the underlying cause, especially in those attested by the DVS, the changes were insufficient to indicate causes that better portray the pathophysiological processes that resulted in stillbirths. Stillbirths rates and avoidable causes increased with the increase in social vulnerability, that is, from the center to the outskirts of the city. Despite the biological vulnerability phenotypes, these proved to be useful indicators of perinatal surveillance that allow the identification of pregnancies with a higher risk of stillbirth.

ABSTRACT

ABSTRACT Objective To assess the association between the maternal diet, according to the degree of processing of food consumption, and birth weight for gestational age and sex. Methods A cross-sectional study with 300 women was conducted from February 2009 to 2011 from a maternity ward in Mesquita, Rio de Janeiro. The outcome was based on sex-specific birth weight for gestational age: small, adequate, or large. A validated food frequency questionnaire was used to estimate the food consumption during the 2nd and 3rd trimesters of pregnancy. The food intake was classified into three groups according to the degree of processing: 1) unprocessed or minimally processed foods and culinary ingredients (oil, fats, salt, and sugar), 2) processed foods, and 3) ultra-processed foods. Descriptive analyses were made to assess the tertiles of the percentage of energy intake of each food group on the outcome and on maternal and infant characteristics. Multinomial logistic regressions were used to test the association of the tertiles of food according to the degree of processing on the outcome (adequate, small, or large birth weight for gestational age and sex). Results The analysis of the food frequency questionnaire from the 300 women indicated that the mean percentage of kcal consumed from unprocessed and minimally processed food and culinary ingredients was 54.0%, while the percentages of energy from processed foods and ultra-processed foods were 2.0% and 44.0%, respectively. The highest tertile of consumption of unprocessed and minimally processed food and culinary ingredients had a protective effect on the prevalence of newborn large for gestational weight in relation to the lowest (OR: 0.13; 95% IC: 0.02 to 0.89; p=0.04). Conclusion High consumption of unprocessed and minimally processed food and culinary ingredients during the last six months of pregnancy might be a protective factor against having a newborn large for gestational weight when compared to mothers with the lowest consumption.


RESUMO Objetivo Avaliar a associação da dieta materna de acordo com o grau de processamento dos alimentos e o peso ao nascer segundo a idade gestacional e sexo. Métodos Estudo transversal com 300 mulheres captadas entre os meses de fevereiro de 2009 e 2011. Utilizou-se a classificação do peso ao nascer segundo sexo e idade gestacional para caracterizar os desfechos: pequeno, adequado ou grande. O questionário de frequência alimentar estimou o consumo durante o 2º e 3º trimestres da gestação. Os alimentos foram classificados segundo o grau de processamento: 1) alimentos in natura ou minimamente processados e ingredientes culinários (óleos, gordura, sal e açúcar), 2) alimentos processados e 3) alimentos ultraprocessados. Os tercis de energia das categorias descritas acima foram distribuídos segundo o desfecho e as características maternas e do recém-nascido. Adotou-se a regressão logística multinomial para analisar a associação do consumo de alimentos segundo o grau de processamento sobre os desfechos do peso ao nascer segundo a idade gestacional e o sexo (pequeno, adequado ou grande). Resultados A análise do questionário de frequência do consumo alimentar das 300 mulheres indicou que a contribuição de alimentos in natura ou minimamente processados e ingredientes culinários foi de 54,0%, enquanto que os percentuais dos grupos de alimentos processados e ultraprocessados foram 2,0% e 44,0%, respectivamente. O maior tercil de alimentos in natura ou minimamente processados e ingredientes culinários obteve efeito protetor para a prevalência de recém-nascidos grandes para a idade gestacional e o sexo em relação ao menor tercil (OR: 0,13; IC 95%: 0,02;0,89; p=0,04). Conclusão O maior consumo de alimentos in natura ou minimamente processados e ingredientes culinários durante a gestação pode ser um fator de proteção contra a ocorrência de recém-nascidos grandes para a idade gestacional e o sexo quando comparado com mães classificadas no menor tercil de consumo.

ABSTRACT

Objective: To explore the characteristics of neonatal adenoid development and to study the relationship between neonatal adenoid development and disease. Methods: A retrospective analysis of neonates who received an electronic rhinopharyngolaryngoscope at Shenzhen Children's Hospital from January 2019 to December 2020 was conducted to track the children's medical history and to analyze the adenoid development status. All 131 neonates successfully completed the electronic laryngoscopy. According to the presence or absence of visible adenoid hyperplasia, they were divided into a hyperplasia group (81 cases, 61.83%) and an un-hyperplasia group (50 cases, 38.17%). Results: Compared with the un-hyperplasia group, the age and birth weight of the adenoid hyperplasia group were larger, and the difference was statistically significant (Z age=-4.634,Z weight=-2.273,all P<0.05), but there was no significant difference in gender and gestational age between the two groups. The number of neonates with rhinitis/sinusitis in the hyperplasia group were significantly more than those in the un-hyperplasia group (62.96% vs 48%). Conclusion: The development of neonatal adenoids is related to daily age, birth weight, but not significantly related to gender and gestational age.

ABSTRACT

Gestational diabetes mellitus (GDM) is common during pregnancy, with the prevalence reaching as high as 31.0% in some European regions (McIntyre et al., 2019). Dysfunction of the glucose metabolism in pregnancy can influence fetal growth via alteration of the intrauterine environment, resulting in an increased risk of abnormal offspring birth weight (McIntyre et al., 2019). Infants with abnormal birth weight will be faced with increased risks of neonatal complications in the perinatal period and chronic non-communicable diseases in childhood and adulthood (Mitanchez et al., 2015; McIntyre et al., 2019). Therefore, accurate estimation of birth weight for neonates from women with GDM is crucial for more sensible perinatal decision-making and improvement of perinatal outcomes. Timely antenatal intervention, with reference to accurately estimated fetal weight, may also decrease the risks of adverse long-term diseases.

ABSTRACT

OBJECTIVES@#To investigate whether evidence-based standardized nutrition protocol can facilitate the establishment of full enteral nutrition and its effect on short-term clinical outcomes in very preterm/very low birth weight infants.@*METHODS@#A retrospective analysis was performed on the medical data of 312 preterm infants with a gestational age of ≤32 weeks or a birth weight of <1 500 g. The standardized nutrition protocol for preterm infants was implemented in May 2020; 160 infants who were treated from May 1, 2019 to April 30, 2020 were enrolled as the control group, and 152 infants who were treated from June 1, 2020 to May 31, 2021 were enrolled as the test group. The two groups were compared in terms of the time to full enteral feeding, the time to the start of enteral feeding, duration of parenteral nutrition, the time to recovery to birth weight, the duration of central venous catheterization, and the incidence rates of common complications in preterm infants.@*RESULTS@#Compared with the control group, the test group had significantly shorter time to full enteral feeding, time to the start of enteral feeding, duration of parenteral nutrition, and duration of central venous catheterization and a significantly lower incidence rate of catheter-related bloodstream infection (P<0.05). There were no significant differences between the two groups in the mortality rate and the incidence rate of common complications in preterm infants including grade II-III necrotizing enterocolitis (P>0.05).@*CONCLUSIONS@#Implementation of the standardized nutrition protocol can facilitate the establishment of full enteral feeding, shorten the duration of parenteral nutrition, and reduce catheter-related bloodstream infection in very preterm/very low birth weight infants, without increasing the risk of necrotizing enterocolitis.

ABSTRACT

To compare different illness severity scores in predicting mortality risk of extremely low birth weight infants (ELBWI). From January 1st, 2019 to January 1st, 2020, all ELBWI admitted in the Children's Hospital of Nanjing Medical University, Nanjing Maternity and Child Health Care Hospital and the First Affiliated Hospital of Nanjing Medical University were included in the study. ELBWI with admission age ≥1 h, gestational age ≥37 weeks and incomplete data required for scoring were excluded. The clinical data were collected, neonatal critical illness score (NCIS), score for neonatal acute physiology version Ⅱ (SNAP-Ⅱ), simplified version of the score for neonatal acute physiology perinatal extension (SNAPPE-Ⅱ), clinical risk index for babies (CRIB) and CRIB-Ⅱ were calculated. The scores of the fatal group and the survival group were compared, and the receiver operating characteristic (ROC) curve was used to evaluate the predictive value of the above illness severity scores for the mortality risk of ELBWI. Pearson correlation analysis was used to analyze the correlation between illness scores and birth weight, illness scores and gestational age. A total of 192 ELBWI were finally included, of whom 114 cases survived (survival group) and 78 cases died (fatal group). There were significant differences in birth weight, gestational age and Apgar scores between fatal group and survival group (all <0.01). There were significant differences in NCIS, SNAP-Ⅱ, SNAPPE-Ⅱ, CRIB and CRIB-Ⅱ between fatal group and survival group (all <0.01). The CRIB had a relatively higher predictive value for the mortality risk. Its area under the ROC curve (AUC) was 0.787, the sensitivity was 0.678, the specificity was 0.804, and the Youden index was 0.482. The scores of NCIS, SNAP-Ⅱ, SNAPPE-Ⅱ, CRIB and CRIB-Ⅱ were significantly correlated with birth weight and gestational age (all <0.05). The correlation coefficients of CRIB-Ⅱ and CRIB with birth weight and gestational age were relatively large, and the correlations coefficients of NCIS with birth weight and gestational age were the smallest (0.191 and 0.244, respectively). Among these five illness severity scores, CRIB has better predictive value for the mortality risk in ELBWI. NCIS, which is widely used in China, has relatively lower sensitivity and specificity, and needs to be further revised.

ABSTRACT

OBJECTIVES@#To develop the birth weight curve of singleton neonates with a gestational age of 24-42 weeks, and to investigate the regional differences of the birth weight curve.@*METHODS@#A total of 11 maternal and child health hospitals with more than 7 000 neonates delivered annually were selected in 11 cities of China (Haikou, Guangzhou, Shenzhen, Liuzhou, Guilin, Quanzhou, Chongqing, Chengdu, Changsha, Ningbo, and Lianyungang), and all live singleton neonates delivered in the 11 hospitals from January 1, 2017 to December 31, 2020 were enrolled for the development of birth weight curves.@*RESULTS@#A total of 93 720 singleton neonates with a gestational age of 24-42 weeks from the 11 cities were included in the study. The reference values of the 3rd-97th percentiles of birth weight of singleton neonates for the total of the 11 cities and for each of the 11 cities were established, and the birth weight percentile curves were drawn. The birth weight curve level of singleton neonates in Shenzhen and Quanzhou was almost the same as the average level of the 11 cities; the birth weight curve level of singleton neonates in Haikou, Guangzhou, Guilin, and Liuzhou was slightly lower than the average level of the 11 cities; the birth weight curve level of singleton neonates in Chongqing, Chengdu, and Changsha was slightly higher than the average level of the 11 cities; the birth weight curve level of singleton neonates in Ningbo and Lianyungang was higher than the average level of the 11 cities. The average birth weight curve level of singleton neonates in the 11 cities were very close to that of China Neonatal Cooperation Network in 2011-2014.@*CONCLUSIONS@#The reference values of the 3rd-97th percentiles of birth weight of singleton neonates for the total of the 11 cities and for each of the 11 cities are developed, which can be used as a reference for evaluating the intrauterine growth of singleton neonates in the region. The level of intrauterine growth of neonates in some cities is different from the national level.

ABSTRACT

Objectives@#It is unclear whether G protein-coupled receptor 61 (GPR61) affecting body weight, plays a role in the association between birth weight and weather. This study aimed to assess the effects of prenatal weather and GPR61 on birth weight.@*Methods@#A total of 567 mother-newborn pairs were recruited in Houzhai Center Hospital during 2011-2012. We detected the maternal and neonatal GPR61 promoter methylation levels, and obtained meteorological and air pollution data.@*Results@#A positive association was observed between maternal and neonatal GPR61 methylation levels, and both of them were affected by precipitation, relative humidity (RH) and daily temperature range (DTR). Birth weight was associated negatively with RH and positively with DTR ( P < 0.05). A significant association was observed between birth weight and neonatal GPR61 methylation. We observed that maternal GPR61 methylation seemed to modify associations between weather and birth weight ( P interaction < 0.10), while neonatal GPR61 methylation mediated the effects of RH and DTR on birth weight ( P < 0.05).@*Conclusions@#Our findings revealed the significant associations among prenatal weather, GPR61 methylation and birth weight. Maternal GPR61 methylation may modify the susceptibility of birth weight to prenatal weather conditions, while neonatal GPR61 methylation may be a bridge of the effects of prenatal RH and DTR on birth weight.

ABSTRACT

La alta prevalencia de sobrepeso y obesidad en las mujeres en edad fértil hace necesario indagar por el impacto que este factor y la ganancia ponderal excesiva en la gestación generan sobre el peso al nacer del neonato. Objetivo: evaluar el efecto del comportamiento del peso materno en dos grupos, gestantes con recién nacido macrosómico y normopeso. Métodos: Estudio longitudinal retrospectivo de medidas repetidas, para comparar la ganancia ponderal en siete momentos de la gestación en dos grupos de gestantes, cuarenta y ocho con recién nacido macrosómico vs cuarenta y ocho normopeso. El estudio se realizó en una institución de segundo nivel de Antioquia-Colombia, a partir de las historias clínicas del control prenatal de los último cinco años. Resultados: Se encontraron diferencias estadísticamente significativas entre grupos, para el peso de los siete momentos del periodo gestacional (p <0,001). El peso gestacional materno, contribuyó a la varianza del peso del neonato, especialmente en el grupo de gestantes con recién nacido macrosómico. Conclusión: La ganancia ponderal materna impacta el peso al nacer, es decir que, a mayor peso gestacional materno, mayor fue el peso del recién nacido(AU)


The high prevalence of overweight and obesity in women of a childbearing age makes it necessary to investigate the impact that this factor and an excessive weight gain in pregnancy have on the weight at birth of the newborn. Objective: To evaluate the effect of maternal weight behavior in two groups, pregnant with a macrosomic newborn and a normal weight. Methods: A retrospective longitudinal study of repeated measures, to compare the weight gain at seven moments of the gestation in two groups of pregnant women, forty-eight with macrosomic newborn vs. forty-eight with a normal weight. The study was carried out in a second-level institution in Antioquia-Colombia, based on the medical records of the prenatal control of the last five years. Results: Statistically significant differences were found between groups for the weight of the seven moments of the gestational period (p <0.001). Maternal gestational weight contributed to the variance of the newborn's weight, especially in the group of pregnant women with a macrosomic newborn. Conclusion: Maternal weight gain impacts birth weight, which means, the higher the maternal gestational weight, the higher the newborn's weight(AU)

ABSTRACT

Objetivo. Determinar la asociación de la velocidad de crecimiento (VC) intrahospitalaria y la fortificación de leche humana con la somatometría y el riesgo de muerte tras el alta o discapacidad grave a los 2 años de edad corregida (EC). Población y método. Análisis retrospectivo de la VC y evolución posterior. Se incluyeron los recién nacidos del período 1990-2015, con peso al nacer < 1500 g. Se excluyeron neonatos con patología que afectaba al crecimiento. Se estudió una cohorte global y dos subcohortes: los nacidos en 1990-2001 (sin fortificación) y los nacidos en 2002-2015 (fortificada). La VC se calculó según la fórmula de Fenton y se consideró adecuada si resultó > 12 g/kg/día. Resultados. Se reclutaron 1194 pacientes. La VC adecuada se asoció a mayor mediana de peso a los 2 años de EC en la cohorte global (11 400 g [10 300-12 500] versus 11 000 g [10 000-12 140], p = 0,02. La cohorte 2002-2015 alcanzó mayor talla media (86,42 ± 4,03 cm versus 85,56 ± 4,01, p = 0,02) y mayor porcentaje de prematuros que alcanzaron un crecimiento compensatorio (catch-up) a los 2 años de EC en la cohorte global con VC adecuada (62,50 % versus 34,69 %, p < 0,02). No se encontraron diferencias en el riesgo de muerte tras el alta o discapacidad grave a los 2 años de EC con VC adecuada (OR: 0,79; IC95 %: 0,47-1,12) ni al considerarse el análisis por subcohortes. Conclusiones. Una VC adecuada se asoció con mejor crecimiento, pero no con menor riesgo de muerte tras el alta o discapacidad grave. La cohorte fortificada alcanzó mayor talla media a los 2 años de EC.


Objective. To determine the association between intrahospital growth rate (GR) and breast milk fortification and somatometry, and risk for death after discharge or severe disability at 2 years of corrected age (CA). Population and method. Retrospective analysis of GR and subsequent course. Infants born in the 1990-2015 period with a birth weight < 1500 g were included. Infants with diseases affecting growth were excluded. An overall cohort and 2 sub-cohorts were studied: infants born in the 1990-2001 period (without fortification) and 2002-2015 period (with fortification). The GR was estimated and deemed adequate if > 12 g/kg/day. Results. A total of 1194 patients were recruited. An adequate GR was associated with a higher median weight at 2 years of CA in the overall cohort (11 400 g [10 300-12 500] versus 11 000 g [10 000-12 140], p = 0.02). The 2002-2015 cohort reached a higher mean height (86.42 ± 4.03 cm versus 85.56 ± 4.01, p = 0.02). More preterm infants caught-up growth at 2 years of CA in the overall cohort with an adequate GR (62.50 % versus 34.69 %, p < 0.02). No differences were observed in the risk for death after discharge or severe disability at 2 years of CA with an adequate GR (OR: 0.79; 95 % confidence interval: 0.47-1.12). Conclusions. An adequate GR was associated with improved growth, but not with a lower risk for death after discharge or severe disability. The cohort with fortified breast milk reached a higher mean height at 2 years of CA

ABSTRACT

Abstract 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 (n = 160) were selected to compose the case group and a random sub-sample of all students participating in the study (n = 276 students, of whom 88 were cases) were the control group. Results: An unadjusted 6% increase in the excess weight prevalence ratio (p-value = 0.004) was found for each 100 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.

ABSTRACT

Introdução: Lactentes nascidos com baixo peso ao nascer em relação a sua idade gestacional são mais propensos à morbimortalidade neonatal e infantil. O Potencial Evocado Auditivo de Tronco Encefálico (PEATE) é uma ferramenta útil para averiguar a atividade neuroelétrica da via auditiva do tronco encefálico. Objetivo: Investigar o efeito do peso e da idade gestacional na via auditiva do tronco encefálico em lactentes. Métodos: Estudo transversal, realizado em um hospital público, no período de janeiro de 2017 a dezembro de 2018, composto por lactentes nascidos pequenos para idade gestacional (PIG), como grupo estudo e lactentes adequados para idade gestacional (AIG), como grupo comparação. Ambos foram semelhantes com relação à idade gestacional, indicadores de risco para deficiência auditiva e idade no momento da avaliação audiológica. Todos foram submetidos aos exames de emissões otoacústicas evocadas por estímulo transiente e PEATE. Resultados: Participaram 172 lactentes com idade média de 1,3 meses para os nascidos PIG e de 1,5 meses para os AIG. Na avaliação por meio do PEATE, houve aumento significativo apenas para os valores das latências absolutas, entretanto, os valores das medianas tanto das latências absolutas como das latências interpicos foram semelhantes entre os grupos. Conclusão: O efeito do peso ao nascimento e da idade gestacional, em lactentes nascidos com peso inferior ao percentil 10, não demonstrou comprometimento da via auditiva no primeiro mês de vida.


Introduction: Infants born with low birth weight in relation to their gestational age are more prone to neonatal and infant morbidity and mortality. Brainstem Auditory Evoked Potential (BAEP) is a useful tool to investigate the neuroelectric activity of the auditory pathway of brainstem. Objective: To investigate the birth weight and gestational age effect on the infants' auditory pathway. Methods: cross-sectional study, conducted in a public hospital from January 2017 to December 2018 composed by small-for-gestational-age (SGA) born infants in the study group, and appropriate-for-gestational-age (AGA) infants, as control group. Both groups were similar in relation to gestational age, risk indicators for hearing loss, and age at the moment of audiological evaluation. All of them were submitted to the exams of transient otoacoustic emissions and BAEP. Results: 172 infants participated, with an average age of 1.3 months for those born SGA and 1.5 months for AGA. In the evaluation using the BAEP, there was a significant increase only in the values of the absolute latencies; however, the median values of both absolute and interpeak latencies were similar between them. Conclusion: The birth weight and gestational age effect in infants born weighing less than the 10th percentile, did not demonstrate impairment on the auditory pathway in the first month of life.

ABSTRACT

Introducción: Objetivo: el objetivo es estimar el peso fetal por métodos clínicos y ecográficos y compararlo con el peso al nacer en recién nacidos a término. Métodos: Se trata de un estudio epidemiológico, observacional, transversal de una cohorte de recién nacidos a término sanos. El tamaño de la muestra fue de 102 neonatos nacidos en el Hospital Pablo Arturo Suárez, en Quito, Ecuador, de noviembre de 2019 a enero de 2020. Resultados: En neonatos a término, la estimación ecográfica fue del 80.00%, mientras que en la valoración clínica fue del 72.29%. El perfil del recién nacido analizado es hombre, mestizo, ecuatoriano, nacido en la región serrana, con una edad gestacional media de 38.67 semanas y un peso medio al nacer de 3.023 gramos, en quienes se estimó el peso fetal mediante ecografía y valoración clínica. La estimación del error absoluto en ambos métodos analizados fue 2.43% para ecografía y -4.65% para valoración clínica, y ambos mostraron concordancia moderada, 78.2% para ecografía y 85.6% para valoración clínica. El análisis multivariado mostró que los recién nacidos con peso modificado por ecografía tienen 13.44 veces más probabilidades de mostrar peso alterado al nacer, mientras que los recién nacidos con peso modificado por la evaluación clínica tienen 11.95 veces más probabilidades de mostrar peso alterado al nacer. Conclusiones: La precisión en la valoración clínica fue siempre mayor que en el método ecográfico, especialmente en los recién nacidos de bajo peso


Introduction: The aim of this trial was to estimate fetal weight by clinical and ultrasound methods and to compare with the weight at birth in full-term newborns. Methods: This is an epidemiological, observational, cross-sectional study of a cohort of healthy full-term newborns. The sample size was 102 neonates born at the Pablo Arturo Suarez Hospital, in Quito, Ecuador, from November 2019 to January 2020. Results: In full-term neonates, the estimate on ultrasound was 80.00%, while in the clinical assessment was 72.29%. The profile of newborn analyzed is man, mestizo, Ecuadorian, born in the highlands region, with a mean gestational age of 38.67 weeks and a mean birth weight of 3,023 grams, in whom it estimated the fetal weight through ultrasound and clinical assessment. The estimation of the absolute error in both methods analyzed was 2.43% to ultrasound and -4.65% to clinical assessment, and both showed moderate concordance, 78.2% to ultrasound, and 85.6% to clinical assessment. Multivariate analysis showed the neo-nates with modified weight by ultrasound are 13.44 times more likely to show altered weight at birth, while neonates with modified weight by the clinical assessment are 11.95 times more likely to show altered weight at birth. Conclusions: Accuracy in the clinical assessment was always higher than in the ultrasound method, especially in low weight newborns.


Introdução: Objetivo: estimar o peso fetal por métodos clínicos e ultrassonográficos e compará-lo com o peso ao nascer em recém-nascidos a termo. Métodos: Este é um estudo epidemiológico, observacional e transversal de uma coorte de recém-nascidos saudáveis ​​a termo. O tamanho da amostra foi de 102 neonatos nascidos no Hospital Pablo Arturo Suárez, em Quito, Equador, de novembro de 2019 a janeiro de 2020. Resultados: Em neonatos a termo, a estimativa ultrassonográfica foi de 80,00%, enquanto na avaliação clínica foi de 72,29%. O perfil do recém-nascido analisado é do sexo masculino, mestiço, equatoriano, nascido na região montanhosa, com idade gestacional média de 38,67 semanas e peso médio ao nascer de 3,023 gramas, sendo o peso fetal estimado por ultrassonografia e avaliação clínica. A estimativa do erro absoluto em ambos os métodos analisados ​​foi de 2,43% para ultrassom e -4,65% para avaliação clínica, e ambos apresentaram concordância moderada, 78,2% para ultrassom e 85,6% para avaliação clínica. A análise multivariada mostrou que os recém-nascidos com peso modificado ultrassonográfico têm 13,44 vezes mais chance de apresentar peso alterado ao nascer, enquanto os recém-nascidos com peso modificado pela avaliação clínica têm 11,95 vezes mais chance de apresentar peso alterado ao nascer. Conclusões: A precisão na avaliação clínica sempre foi maior do que no método ultrassonográfico, principalmente em recém-nascidos de baixo peso.
