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.

ABSTRACT

Abstract Objectives: to perform a systematic review of studies that investigated the influence of ultra-processed foods (UPF) consumption during pregnancy on child's anthropometric parameters up to one year of life. Methods: cohort and cross-sectional studies were researched in BVS, Cinahl, Cochrane, Embase, Pubmed, Scopus and Web of Science databases until March 2020, and the main descriptors were: "Pregnant Women", "Ultra-processed foods", "Birth Weight", "Smallfor Gestational Age", "Infant", "Newborn". Results: seventeen articles were considered eligible and evaluated the associations between the exposures: ultra-processed dietary patterns; soft drinks, sugar-sweetened beverages, artificially sweetened beverages; fast food, junk food, sweets, snacks and the outcomes: birth weight and its classifications; length and head circumference at birth; birth weight adjustments according to gestational age; weight/age, length/age, body mass index/age and weight/length indices. The results showed: 36 non-significant associations between the exposures and the outcomes; 13 direct associations (outcomes versus ultraprocessed dietary patterns, soft drinks, artificially sweetened beverages, sweets, junk food) and 5 inverse associations (outcomes versus ultra-processed dietary patterns, soft drinks). Conclusions: most of the evaluated literature did not demonstrate the influence of UPF consumption during pregnancy on the newborn's anthropometric measurements up to one year of life and denoted a smaller number of direct and inverse associations between the exposures and the outcomes.


Resumo Objetivos: realizar uma revisão sistemática de estudos que investigaram a influência do consumo de alimentos ultraprocessados (AUP) na gestação nas medidas antropométricas do recém-nascido até um ano de idade. Métodos: foram pesquisados estudos de coorte e transversais nas bases BVS, Cinahl, Cochrane, Embase, Pubmed, Scopus e Web of Science até março de 2020, tendo como principais descritores: "Pregnant women", "Ultra-processed foods", "Birth weight", "Small for Gestational Age", "Infant", "Newborn". Resultados: dezessete artigos foram considerados elegíveis e avaliaram as associações entre as exposições: padrões alimentares ultraprocessados; refrigerantes, sugar-sweetened beverages ou artificially sweetened beverages; fastfood, junkfood, doces e snacks e os desfe-chos:peso ao nascer e suas classificações; comprimento e perímetro cefálico ao nascimento; adequações do peso ao nascer segundo idade gestacional; e índices peso/idade, compri-mento/idade, índice de massa corporal/idade e peso/comprimento. Foram encontradas: 36 associações nulas entre exposições e desfechos avaliados; 13 diretas (desfechos versus padrões alimentares ultraprocessados, refrigerantes, artificially sweetened beverages, doces e junkfood) e 5 inversas (desfechos versus padrões alimentares ultraprocessados e refrigerantes). Conclusões: a maioria da literatura avaliada não demonstrou influência do consumo de AUP na gestação nas medidas antropométricas do recém-nascido até um ano de vida e apontou um menor número de associações diretas e inversas entre as exposições e os desfechos analisados.

ABSTRACT

Abstract Objectives: to determine the relationship between maternal hemoglobin (HbM) per gestational trimester and birthweight (BW). Methods: this was an analytical, cross-sectional observational study that included the prenatal records of494 pregnant women who delivered live newborns in the Department of Antioquia. The maternal health data collected included HbM and BW, and gynecological and obstetric, anthropometric, and maternal health-related data. The Mann-Whitney U test was applied, supplemented by effect size (ES) to compare the study groups. Results: HbMin the third trimester was significantly associated with BW (p=0.029).It showed a significant effect size on BW as follows: first trimester: ES=0.44 (CI95%= 0.183-0.697); second trimester: ES=0.49 (CI95%= 0.187-0.79); and third trimester: ES=0.43 (CI95% = 0.202-0.658). Maternal anemia was 4.2%>, 11.2%, and 21.4%> in the first, second, and third trimester, respectively. Conclusions: as it is an inexpensive indicator and easy to determine, the timely monitoring and assessment of HbM is required owing to its importance in maternal and neonatal health, quality of life, and human capital development.

ABSTRACT

Given the increase of women with excess weight or obesity and its possible effects on birth weight, the present study aimed to investigate the association between pregestational maternal body mass index (BMI) and birth weight in a birth cohort from Ribeirão Preto, SP, Brazil. This was a prospective study conducted on 1362 mother-child pairs involving singleton births. The women were evaluated using standardized questionnaires during the second trimester of pregnancy and at the time of childbirth. Information about the newborns was obtained from their medical records. The dependent variable was birth weight, categorized as low, adequate, or high. The independent variable was pregestational maternal BMI, categorized as malnutrition, adequate weight, overweight, and obesity. A multinomial regression model was used to estimate the crude and adjusted relative risk (RR) of low and high birth weight. A high frequency of pregestational excess weight (39.6%) was detected and found to be independently associated with high birth weight (RR=2.13, 95%CI: 1.19-3.80 for overweight and RR=3.34, 95%CI: 1.80-6.19 for obese pregnant women). There was no association between pregestational malnutrition and low birth weight (RR=1.70; 95%CI: 0.81-3.55). The present data showed a high rate of women with excess pregestational weight, supporting the hypothesis that pregestational BMI may contribute to high birth weight babies and indicating the need for actions aiming to prevent excessive weight in women at reproductive age.

ABSTRACT

OBJECTIVE@#To evaluate the clinical features of preterm infants with a birth weight less than 1 500 g undergoing different intensities of resuscitation.@*METHODS@#A retrospective analysis was performed for the preterm infants with a birth weight less than 1 500 g and a gestational age less than 32 weeks who were treated in the neonatal intensive care unit of 20 hospitals in Jiangsu, China from January 2018 to December 2019. According to the intensity of resuscitation in the delivery room, the infants were divided into three groups:non-tracheal intubation (@*RESULTS@#Compared with the non-tracheal intubation group, the tracheal intubation and ECPR groups had significantly lower rates of cesarean section and use of antenatal corticosteroid (@*CONCLUSIONS@#For preterm infants with a birth weight less than 1 500 g, the higher intensity of resuscitation in the delivery room is related to lower rate of antenatal corticosteroid therapy, lower gestational age, and lower birth weight. The infants undergoing tracheal intubation or ECRP in the delivery room have an increased incidence rate of adverse clinical outcomes. This suggests that it is important to improve the quality of perinatal management and delivery room resuscitation to improve the prognosis of the infants.

ABSTRACT

OBJECTIVE@#To investigate the incidence rate and risk factors for metabolic bone disease of prematurity (MBDP) in very low birth weight/extremely low birth weight (VLBW/ELBW) infants.@*METHODS@#The medical data of 61 786 neonates from multiple centers of China between September 1, 2013 and August 31, 2016 were retrospectively investigated, including 504 VLBW/ELBW preterm infants who met the inclusion criteria. Among the 504 infants, 108 infants diagnosed with MBDP were enrolled as the MBDP group and the remaining 396 infants were enrolled as the non-MBDP group. The two groups were compared in terms of general information of mothers and preterm infants, major diseases during hospitalization, nutritional support strategies, and other treatment conditions. The multivariate logistic regression analysis was used to investigate the risk factors for MBDP.@*RESULTS@#The incidence rate of MBDP was 19.4% (88/452) in VLBW preterm infants and 38.5% (20/52) in ELBW preterm infants. The incidence rate of MBDP was 21.7% in preterm infants with a gestational age of < 32 weeks and 45.5% in those with a gestational age of < 28 weeks. The univariate analysis showed that compared with the non-MBDP group, the MBDP group had significantly lower gestational age and birth weight, a significantly longer length of hospital stay, and a significantly higher incidence rate of extrauterine growth retardation (@*CONCLUSIONS@#A lower gestational age, hypocalcemia, extrauterine growth retardation at discharge, and neonatal sepsis may be associated an increased risk of MBDP in VLBW/ELBW preterm infants. It is necessary to strengthen perinatal healthcare, avoid premature delivery, improve the awareness of the prevention and treatment of MBDP among neonatal pediatricians, and adopt positive and reasonable nutrition strategies and comprehensive management measures for preterm infants.

ABSTRACT

OBJECTIVE@#To study the association of different stages of histological chorioamnionitis (HCA) with the incidence rate and severity of respiratory distress syndrome (RDS) in preterm infants.@*METHODS@#Related data were collected from the infants and their mothers who were treated in the Neonatal Intensive Care Unit of Qingdao Women and Children's Hospital, Qingdao University, from January 2018 to June 2020. According to the presence or absence of HCA and its stage, the infants were divided into four groups: control (@*RESULTS@#Compared with the control and late-stage HCA groups, the early-stage HCA group had a significantly lower incidence rate of placental abruption and a significantly higher rate of prenatal use of antibiotics (@*CONCLUSIONS@#Early-, middle-, and late-stage HCA can reduce the incidence rate of RDS in preterm infants. HCA stage may not be correlated with RDS severity in preterm infants, which needs to be verified by further research.

ABSTRACT

OBJECTIVE@#To study the clinical effect of multi-oil fat emulsion for parenteral nutrition support in extremely low birth weight (ELBW) infants.@*METHODS@#A retrospective analysis was performed for 49 ELBW infants who were admitted from January 1, 2018 to July 30, 2020, with an age of ≤14 days on admission and a duration of parenteral nutrition of > 14 days. According to the type of lipid emulsion received, the ELBW infants were divided into two groups: soybean oil, medium-chain triglycerides, olive oil, and fish oil (SMOF) (@*RESULTS@#The 49 ELBW infants had a mean birth weight of (892±83) g and a mean gestational age of (28.2±2.3) weeks. There was no significant difference between the two groups in the incidence rates of hemodynamically significant patent ductus arteriosus, intraventricular hemorrhage, neonatal necrotizing enterocolitis, retinopathy of prematurity, bronchopulmonary dysplasia (BPD), grade Ⅲ BPD, sepsis, and pneumonia (@*CONCLUSIONS@#The application of multi-oil fat emulsion in ELBW infants does not reduce the incidence rate of complications, but compared with MCT/LCT emulsion, SMOF can reduce the severity of PNAC in ELBW infants.

ABSTRACT

BACKGROUND@#Fetal weight is an important parameter to ensure maternal and child safety. The purpose of this study was to use three-dimensional (3D) limb volume ultrasound combined with fetal abdominal circumference (AC) measurement to establish a model to predict fetal weight and evaluate its efficiency.@*METHODS@#A total of 211 participants with single pregnancy (28-42 weeks) were selected between September 2017 and December 2018 in the Beijing Obstetrics and Gynecology Hospital of Capital Medical University. The upper arm (AVol)/thigh volume (TVol) of fetuses was measured by the 3D limb volume technique. Fetal AC was measured by two-dimensional ultrasound. Nine cases were excluded due to incomplete information or the interval between examination and delivery >7 days. The enrolled 202 participants were divided into a model group (134 cases, 70%) and a verification group (68 cases, 30%) by mechanical sampling method. The linear relationship between limb volume and fetal weight was evaluated using Pearson Chi-squared test. The prediction model formula was established by multivariate regression with data from the model group. Accuracy of the model formula was evaluated with verification group data and compared with traditional formulas (Hadlock, Lee2009, and INTERGROWTH-21st) by paired t-test and residual analysis. Receiver operating characteristic curves were generated to predict macrosomia.@*RESULTS@#AC, AVol, and TVol were linearly related to fetal weight. Pearson correlation coefficient was 0.866, 0.862, and 0.910, respectively. The prediction model based on AVol/TVol and AC was established as follows: Y = -481.965 + 12.194TVol + 15.358AVol + 67.998AC, R2adj = 0.868. The scatter plot showed that when birth weight fluctuated by 5% (i.e., 95% to 105%), the difference between the predicted fetal weight by the model and the actual weight was small. A paired t-test showed that there was no significant difference between the predicted fetal weight and the actual birth weight (t = -1.015, P = 0.314). Moreover, the residual analysis showed that the model formula's prediction efficiency was better than the traditional formulas with a mean residual of 35,360.170. The combined model of AVol/TVol and AC was superior to the Lee2009 and INTERGROWTH-21st formulas in the diagnosis of macrosomia. Its predictive sensitivity and specificity were 87.5% and 91.7%, respectively.@*CONCLUSION@#Fetal weight prediction model established by semi-automatic 3D limb volume combined with AC is of high accuracy, sensitivity, and specificity. The prediction model formula shows higher predictive efficiency, especially for the diagnosis of macrosomia.@*TRIAL REGISTRATION@#ClinicalTrials.gov, NCT03002246; https://clinicaltrials.gov/ct2/show/NCT03002246?recrs=e&cond=fetal&draw=8&rank=67.

ABSTRACT

ABSTRACT OBJECTIVE: Determine the value of the combination of fasting glucose less than the 10th percentile (FG < p10) during 75 gram oral glucose tolerance test (75g OGTT) with maternal characteristics to predict low birth weight (LBW) established by Intergrowth-21st tables. METHODS: Prospective cohort study of pregnant women who was underwent 75g OGTT between 24 and 28.6 weeks. The 10th percentile fasting glucose of the population was determined at 65 mg/dL and women with risk factors that could modify fetal weight, including those related to intrauterine growth restriction, were excluded. Two groups were formed: group FG < p10 and group with normal fasting glucose. The main finding was the diagnosis of LBW. The association between FG < p10, maternal characteristics and LBW was established by multivariate logistic regression. The predictive performance of the models constructed was evaluated by receiver operating characteristic (ROC) curve and area under the curve (AUC) analysis. RESULTS: 349 women were eligible for study, of whom 66 (18.91%) had FG < p10; neonates in this group had lower birth weights (2947.28 g and 3138.26 g, p = 0.001), higher frequencies of LBW (25% and 6.81%, p < 0.001) and of weights < 2500 g in term births (8.6% and 2.3%, p = 0.034). The basal prediction model consisted of nulliparity by achieving an AUC of 60%, while the addition of FG < p10 resulted in the significant improvement of the previous model (AUC 72%, DeLong: p = 0.005). CONCLUSIONS: In pregnant women without factors that could modify fetal weight, the predictive model created by combining FG < p10 during 75g OGTT with nulliparity was significantly associated with increased risk of LBW. REGISTRATION: ClinicalTrials.gov: NCT04144595.


RESUMEN OBJETIVO: Determinar el valor de la combinación de la glucosa en ayunas menor que el percentil 10 (GA < p10) durante la prueba de tolerancia oral a la glucosa con 75 gramos (PTG-75g) con características maternas para predecir bajo peso al nacer (BPN) establecido mediante tablas de Intergrowth-21st. MÉTODOS: Estudio de cohorte prospectivo de mujeres embarazadas que se realizaron PTG-75g entre las 24 y 28.6 semanas. Se determinó el percentil 10 de glucosa en ayunas de la población en 65 mg/dL y fueron excluidas aquellas mujeres con factores de riesgo que pudieran modificar el peso fetal incluyendo los relacionados con la restricción del crecimiento intrauterino. Se formaron dos grupos: grupo GA < p10 y grupo con glucosa en ayunas normal. El hallazgo principal fue el diagnóstico de BPN. La asociación entre GA < p10, características maternas y BPN se estableció mediante regresión logística multivariante. El desempeño predictivo de los modelos construidos fue evaluado por el análisis de la curva característica operativa del receptor (ROC) y del área bajo la curva (ABC). RESULTADOS: Fueron elegibles para estudio 349 mujeres, de las cuales 66 (18,91%) tuvieron GA < p10; los neonatos de este grupo tuvieron pesos al nacer más bajos (2947.28 g y 3138.26 g, p = 0,001), frecuencias más altas de BPN (25% y 6,81%, p < 0,001) y de pesos < 2500 g en nacimientos de término (8,6% y 2,3%, p = 0,034). El modelo basal de predicción consistió en nuliparidad al lograr un ABC del 60%, mientras que al añadir la GA < p10 se obtuvo la mejora significativa del modelo previo (ABC 72%, DeLong: p = 0,005). CONCLUSIONES: En mujeres embarazadas sin factores que pudieran modificar el peso fetal, el modelo predictivo creado combinando GA < p10 durante la PTG-75g con nuliparidad estuvo asociado significativamente con riesgo incrementado de BPN. REGISTRO: ClinicalTrials.gov: NCT04144595.

ABSTRACT

Introducción: la programación fetal ofrece nuevas perspectivas sobre el origen de las enfermedades cardiovasculares, relacionando su aparición con factores perinatales. Objetivo: exponer evidencia que vincule las alteraciones gestacionales con las enfermedades cardiovasculares en la vida adulta del feto. Metodología: búsqueda en las bases de datos EBSCO, COCHRANE, MEDLINE, PROQUEST y SciELO de los artículos de revisión e investigaciones originales en inglés publicados en los últimos diez años. Se utilizaron términos MeSH para búsqueda controlada y se evaluaron los estudios con STROBE y PRISMA según correspondía. Resultados: los hallazgos sugieren que nacer con menos de 2600 k guarda relación con diabetes mellitus (OR de 1.607 IC 95% 1.324-1.951), hipertensión arterial (OR de 1.15 IC 95% 1.043-1.288) y menor función endotelial (1.94+0.37 vs 2.68+0.41, p: 0.0001) en la adultez. La prematuridad se asocia con mayores presiones arteriales sistólicas (4.2 mmHg IC 95%; 2.8 - 5.7 p 0.001) y diastólicas (2.6 mmHg IC 95%; 1.2-4.0; p 0.001). Las alteraciones nutricionales maternas y la diabetes gestacional aumentan el riesgo de síndrome metabólico (OR 1.2 IC 95% 0.9-1.7) y sobrepeso en la edad escolar (OR 1.81 IC 95% 1.18 - 2.86). Conclusión: los resultados adversos en la gestación están relacionados con el desarrollo de enfermedades cardiovasculares en la vida adulta del feto expuesto.


Introduction: fetal programming offers new perspectives on the origin of cardiovascular diseases, relating their appearance with perinatal factors. Objective: to show the evidence associating gestational alterations with cardiovascular diseases in the offspring in adult life. Methodology: an EBSCO, COCHRANE, MEDLINE, PROQUEST and SciELO databases search of original review and research articles published in English in the last ten years was conducted. MeSH terms were used to perform a controlled search. The studies were analyzed accordingly using the STROBE and PRISMA reporting guidelines. Results:The findings suggest that a birth weight of less than 2600 kg is related with diabetes mellitus (OR = 1.607, 95% CI 1.324 to 1.951), hypertension (OR = 1.15, 95% CI 1.043 to 1.288) and impaired endothelial function (1.94+0.37 vs 2.68+0.41, p: 0.0001) in adulthood. Prematurity is related with higher systolic blood pressure (4.2 mmHg 95% CI; 2.8 to 5.7 p 0.001) and diastolic blood pressure (2.6 mmHg 95% CI; 1.2 to 4.0; p 0.001). Maternal nutritional alterations and gestational diabetes increase the risk of metabolic syndrome (OR = 1.2 95% CI 0.9 to 1.7) and overweight in school-age (OR = 1.81 95% CI 1.18 to 2.86). Conclusion: adverse results during pregnancy are related with the development of cardiovascular diseases in the exposed fetus in adult life.

ABSTRACT

Objective: to investigate associations between depressive symptoms during pregnancy, low birth weight, and prematurity among women with low-risk pregnancies assisted in public Primary Health Care services. Method: prospective cohort with 193 pregnant women, using the Edinburgh Postnatal Depression Scale, telephone interviews, and medical records available in the health services. Associations of interest were obtained using the Cox regression model. Results: the participants were aged 24.9 years old (median) and had 11 years of schooling (median); 82.4% lived with their partners, and gestational age at the birth was 39 weeks (median). Twenty-five percent of the participants scored ≥13 on the Edinburgh scale. Depressive symptoms did not appear associated with low birth weight (RR=2.06; CI95%=0.56-7.61) or prematurity (RR=0.86; CI95%=0.24-3.09) in the adjusted analysis. However, premature labor increased the risk of low birth weight (RR=4.81; CI95%=1.01-23.0) and prematurity (RR=7.70; CI95%=2.50-23.7). Additionally, each week added to gestational age decreased the risk of low birth weight (RR=0.76; CI95%=0.61-0.95). Conclusion: the presence of depressive symptoms among women with low-risk pregnancies was not associated with low birth weight or prematurity.


Objetivo: investigar a associação entre sintomas depressivos na gestação, baixo peso ao nascer e prematuridade entre gestantes de baixo risco obstétrico, atendidas em serviços públicos de Atenção Primária à Saúde. Método: coorte prospectiva com 193 gestantes, mediante aplicação da Escala de Depressão Pós-natal de Edimburgo, entrevista telefônica e consulta aos prontuários dos serviços de saúde. As associações de interesse foram obtidas por regressão múltipla de Cox. Resultados: as participantes tinham idade mediana de 24,9 anos e escolaridade mediana de 11 anos; 82,4% viviam com companheiro e a idade gestacional mediana no parto foi 39 semanas. Auferiram escore ≥13 na Escala de Edimburgo 25,4% delas. Na análise ajustada, sintomas depressivos não se associaram ao baixo peso ao nascer (RR=2,06; IC95%=0,56-7,61) e à prematuridade (RR=0,86; IC95%=0,24-3,09). Secundariamente, identificouse que trabalho de parto prematuro aumentou o risco de baixo peso ao nascer (RR=4,81; IC95%=1,01-23,0) e de prematuridade (RR=7,70; IC95%=2,50-23,7). Além disso, cada semana a mais na idade gestacional diminuiu o risco de baixo peso ao nascer (RR=0,76; IC95%=0,61-0,95). Conclusão: a presença de sintomas depressivos entre gestantes de baixo risco obstétrico não se associou ao risco de baixo peso ao nascer e prematuridade.


Objetivo: investigar la asociación entre síntomas depresivos en la gestación con bajo peso al nacer y prematuridad entre embarazadas, de bajo riesgo obstétrico, atendidas en servicios públicos de Atención Primaria a la Salud. Método: cohorte prospectiva en 193 embarazadas, utilizando la Escala de Depresión Posparto de Edimburgo, por medio de entrevista telefónica y consulta en las fichas médicas de los servicios de salud. Las asociaciones de interés fueron obtenidas con la regresión múltiple de Cox. Resultados: las participantes tuvieron edad mediana de 24,9 años y escolaridad mediana de 11 años; 82,4% vivían con compañero y la edad gestacional mediana en el parto fue 39 semanas. 25,4% de las mujeres obtuvieron un puntaje ≥13, en la Escala de Edimburgo. En el análisis ajustado, los síntomas depresivos no se asociaron al bajo peso al nacer (RR=2,06; IC95%=0,56-7,61) y a la prematuridad (RR=0,86; IC95%=0,24-3,09). Secundariamente, se identificó que el trabajo de parto prematuro aumentó el riesgo de bajo peso al nacer (RR=4,81; IC95%=1,01-23,0) y de prematuridad (RR=7,70; IC95%=2,50-23,7). Además de eso, se encontró que cada semana a más en la edad gestacional disminuye el riesgo de bajo peso al nacer (RR=0,76; IC95%=0,61-0,95). Conclusión: la presencia de síntomas depresivos entre embarazadas de bajo riesgo obstétrico no se asoció al riesgo de bajo peso al nacer y a la prematuridad.

ABSTRACT

Introdução: Após o nascimento de um bebê, são realizadas medidas antropométricas, como peso, comprimento e perímetro cefálico. Especificamente o peso de nascimento é considerado como diretamente relacionado às características do futuro crescimento e desenvolvimento da criança. A partir de referenciais já publicados, de acordo com a Idade Gestacional (IG), esses parâmetros antropométricos são avaliados como adequados ou não e podem ser importantes preditores da saúde e dos cuidados que o recém-nascido (RN) irá demandar. Há mais de meio século, curvas referenciais de crescimento têm sido propostas e utilizadas. Atualmente, estão entre as mais utilizadas a proposta por Fenton e Kim e a produzida pelo estudo INTERGROWTH-21st. Na literatura encontra-se uma diversidade de estudos comparando essas curvas de crescimento, analisando sua adequação. Partindo dessas premissas e visando contribuir para este tipo de análise e discussão acerca dos referenciais de crescimento intrauterino, mormente para os recém-nascidos de termo, que representam a grande maioria dos nascimentos, optou-se por avaliar os dados de antropometria ao nascimento de um universo de recém-nascidos de termo, resultantes de gestações de baixo risco, filhos de mães adultas jovens residentes em um município brasileiro de elevado Índice de Desenvolvimento Humano e com cobertura praticamente universal de saneamento básico. Objetivo: Analisar as medidas antropométricas ao nascimento de RN a termo, nascidos de mães adultas jovens, em uma cidade de elevado IDH, no período de maio de 2015 a março de 2018. A partir desses dados, buscou-se compará-los com as curvas propostas pelos estudos de Fenton e Kim e INTERGROWTH-21st, incluindo a mediana e os percentis 10 e 90 de cada parâmetro, segundo o sexo e IG. Metodologia: Estudo descritivo e analítico, quantitativo, com coleta retrospectiva de dados provenientes do Hospital Universitário de Taubaté, das crianças nascidas entre maio de 2015 e março de 2018. Dados foram tabulados e analisados, calculadas medidas de tendência central e dispersão por grupos de análise. Calculadas curvas de regressão não linear e, posteriormente, comparadas com os referenciais com escore Z. Resultados: No período elegido ocorreram 6757 nascimentos vivos; destes, foram incluídos no estudo 3908. Verificou-se um predomínio do sexo feminino e em relação à IG, a maioria foi de RN de termo pleno com predomínio de partos vaginais, exceto para os termos tardios. Quanto ao peso, mais de 90% com peso adequado para a IG. O incremento de peso foi de aproximadamente 100g por semana e no comprimento de 0,4 a 0,5cm por semana. Ao serem comparados os parâmetros antropométricos, em relação à via de parto, encontramos bebês mais leves, menores em comprimento e perímetro cefálico, para via vaginal. Em relação ao sexo, ambos se concentraram com IG de termo pleno, o sexo masculino com valores ligeiramente maiores nos três parâmetros analisados. Na comparação com o referencial de Fenton e Kim, o peso e PC apresentaram valores acima do referencial na 37ª semana e a seguir valores abaixo, enquanto o comprimento desde a 37ª semana apresentou-se abaixo do referencial. Quando comparado com os gráficos do INTERGROWTH-21st, o peso apresenta-se com valores maiores que o referencial até 40ª semana em todos os percentis, diferente do comprimento, onde praticamente todos os valores estão abaixo do referencial, os dados do PC, nos percentis 50 e 90, apresentam-se maior que o referencial, em quase todas as IG. Conclusão: RN de termo, de gestações de baixo risco de mães adultas jovens, apresentam valores de antropometria ao nascimento diferentes dos propostos pelos referenciais de Fenton e Kim e do estudo INTERGROWTH-21st. No que se refere à tendência de evolução dos escores Z (percentis) entre as idades gestacionais referidas como de termo (37ª até 41ª semana), tanto para o peso quanto para o comprimento e o perímetro craniano ao nascer, ela é sempre decrescente, indicando uma velocidade de crescimento menor do que a previsível a partir das curvas de referência. Encontraram-se menores diferenças entre os valores absolutos de peso, de comprimento e de perímetro craniano ao nascer, com os respectivos valores indicados pelo referencial do INTERGROWTH 21st. Ficando evidente a impossibilidade de existir uma única curva referencial universal, sendo necessária uma compreensão crítica para a sua utilização. Os resultados deste estudo não invalidam os referenciais, mas podem contribuir para que sejam utilizados de forma mais adequada e consistente.


Introduction: Anthropometric measures, such as weight, length and cephalic perimeter, are performed after the birth of a baby. In particular, birth weight is considered causally related to the characteristics of future child growth and development. Based on already published references, according to the Gestational Age (GA), these anthropometric parameters are assessed as appropriate or not and may be important predictors of the health and care that the newborn (NB) will demand. More than half a century ago, reference growth curves have been proposed and used. Currently, they are among the most used proposals by Fenton and Kim and those produced by study INTERGROWTH-21st. In the literature there is a diversity of studies comparing these growth curves, analyzing their adequacy. Based on these assumptions and aiming to contribute to this type of analysis and discussion about the intrauterine growth references, particularly for the newborn at term, which represent most births, it was chosen to evaluate anthropometric data at the birth of a universe of newborn at term, result of low-risk gestation, children of young adult mothers resident in a Brazilian municipality with high Human Development Index and with almost whole coverage of sanitation. Objective: Analysis of anthropometric measures at birth of NB at term, born of young adult mothers, in a city with high HDI, from May 2015 to March 2018. Based on these data, it was sought to compare them with the curves proposed by the studies of Fenton and Kim and INTERGROWTH-21st, including the median and percentiles 10 and 90 of each parameter, according to gender and GA. Methodology: A quantitative descriptive and analytical study with retrospective collection of data from Hospital Universitário de Taubaté of children born between May 2015 and March 2018. Data were tabled and analyzed, central tendency measurements and dispersion by analysis groups were calculated. Calculated non-linear regression curves and then compared to the Z-score references. Results: 6757 live births occurred in the selected period; of these, were included in study 3908. There was a predominance of female sex and in relation to GA, most of them were full-term NBs with predominance of vaginal births, except for late term. As for weight, more than 90% with appropriate weight for GA. Weight gain was approximately 100g per week and in length from 0.4 to 0.5cm per week. When comparing the anthropometric parameters in relation to the delivery route, we found milder, smaller babies in length and cephalic perimeter, for vaginal route. Regarding sex, both concentrated on full-term GA, male with slightly higher values in the three parameters analyzed. Compared to the Fenton and Kim reference, weight and PC presented values above the reference at week 37 and below, while length from week 37 was below the reference. When compared to the graphs of INTERGROWTH-21st, the weight is greater than the reference up to week 40 in all percentages, different from the length, where virtually all values are below the reference, the PC data in percentiles of 50 and 90 are greater than the reference, in almost all GAs. Conclusion: NB at term, low-risk pregnancies of young adult mothers, - present anthropometric values at birth different from those proposed by Fenton and Kim references and the INTERGROWTH-21st study. Regarding the trend of evolution of Z-scores (percentiles) between the gestational ages referred to as term (37th to 41st weeks), For both weight and cranial length and perimeter at birth, it is always decreasing, indicating a growth rate lower than predicted from the reference curves. There were smaller differences between absolute values of weight, length and cranial perimeter at birth, with the respective values indicated by the reference of INTERGROWTH 21st. It is evident that there is no single universal reference curve, A critical understanding is needed for its use. The results of this study do not invalidate the references but can contribute to their more appropriate and consistent use.

ABSTRACT

Intrauterine life is a critical period for the development of body fat and metabolic risk. This study investigated associations between birth weight and total and truncal body fat in adults. To do so, we analyzed data on 10,011 adults participating in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) who self-reported birth weight as < 2.5kg, 2.5-4.0kg, or > 4.0kg at baseline (2008-2010) and underwent bioimpedance in the next follow-up visit (2012-2014). Greater mean total and truncal fat mass were seen in those with high birth weight compared with adequate birth weight (p < 0.001) in both sexes (total fat: 25.2 vs. 23.1kg in men and 31.4 vs. 27.7kg in women, and truncal fat: 13.5 vs. 12.4kg in men and 15.9 vs. 14.2kg in women). U-shaped patterns were observed in restricted cubic-spline analyses in the subset of 5,212 individuals reporting exact birth weights, although statistically significant only for those with high birth weight. In the whole sample, in comparing high to adequate birth weight, the latter predicted having a large (> 85 percentile) total and truncal fat mass, respectively: OR = 1.76, 95%CI: 1.37-2.25 (men) and OR = 1.86, 95%CI: 1.42-2.44 (women); OR = 1.68, 95% CI: 1.31-2.16 (men) and OR = 1.73, 95%CI: 1.31-2.28 (women). However, low birth weight predicted having a large (> 85 percentile) % truncal fat only in women (OR = 1.40, 95%CI: 1.03-1.91). In conclusion, in these men and women born in a period in which fetal malnutrition was prevalent, birth weight showed complex, frequently non-linear associations with adult body fat, highlighting the need for interventions to prevent low and high birth weight during pregnancy.


A vida intrauterina é um período crítico para o desenvolvimento da gordura corporal e risco metabólico. O estudo investigou as associações entre peso ao nascer e gordura corporal total e de tronco em adultos. Analisamos os dados de 10.011 participantes do Estudo Longitudinal de Saúde no Adulto (ELSA-Brasil), com peso ao nascer de < 2,5kg, 2,5-4,0kg ou > 4,0kg, autorrelatado na linha de base (2008-2010) e que fizeram exame de bioimpedância na visita seguinte (2012-2014). A gordura corporal total e de tronco mais elevada estava associada com peso ao nascer elevado, quando comparado ao peso adequado (p < 0,001) em ambos os sexos (gordura total: 25,2 vs. 23,1 kg em homens e 31,4 vs. 27,7kg em mulheres, e gordura de tronco: 13,5 vs. 12,4kg em homens e 15,9 vs. 14,2kg em mulheres). Foram observados padrões em "U" nas análises de splines cúbicos restritos, no subconjunto de 5.212 indivíduos que informaram o peso ao nascer com exatidão, embora com significância estatística apenas para aqueles com peso ao nascer alto. Na amostra total, o peso ao nascer alto (comparado com o adequado) predizia (> percentil 85) gordura corporal total e de tronco, respectivamente: OR = 1,76, IC95%: 1,37-2,25 (homens) e OR = 1,86, IC95%: 1,42-2,44 (mulheres); OR = 1,68, IC95%: 1,31-2,16 (homens) e OR = 1,73, IC95%: 1,31-2,28 (mulheres). Entretanto, baixo peso ao nascer predizia gordura de tronco elevada (> percentil 85) apenas nas mulheres (OR = 1,40, IC95%: 1,03-1,91). O estudo conclui que nesse grupo de homens e mulheres que nasceram numa época em que a desnutrição fetal era prevalente, o peso ao nascer mostrou associações complexas, frequentemente não lineares, com a gordura corporal na idade adulta, o que enfatiza a necessidade de intervenções para prevenir, durante a gestação, o baixo e alto peso ao nascer.


La vida intrauterina es un periodo crítico para el desarrollo de la masa de grasa corporal y riesgo metabólico. Investigamos las asociaciones entre peso al nacer y la grasa total y troncal en adultos. Analizamos datos de 10.011 adultos que participaron en el Estudio Longitudinal de Salud en Adultos (ELSA-Brasil) quienes autoinformaron de un peso al nacer < 2,5kg, 2,5-4,0kg, o > 4,0kg en la base de referencia (2008-2010) y experimentaron bioimpedancia en la siguiente visita de seguimiento (2012-2014). La mayor media de masa grasa total y troncal se observó en quienes tuvieron un alto peso al nacer, en comparación con quienes tuvieron un adecuado peso al nacer (p < 0,001) en ambos sexos (grasa total: 25,2 vs. 23,1kg en hombres y 31,4 vs. 27,7kg en mujeres, y grasa troncal: 13,5 vs. 12,4kg en hombres y 15,9 vs. 14,2kg en mujeres). Se observaron patrones en forma de "U" en análisis spline cúbicos restringidos en el subconjunto de 5.212 personas que informaron de sus pesos exactos al nacer, pese a que eran estadísticamente significativos solamente quienes tenían un alto peso al nacer. En toda la muestra con alto peso al nacer, comparada con el adecuado peso al nacer, se pronosticó contar con más masa grasa total y troncal (> percentil 85), respectivamente: OR = 1,76, IC95%: 1,37-2,25 (hombres) y OR = 1,86, IC95%: 1,42-2,44 (mujeres); OR = 1,68, IC95%: 1,31-2,16 (hombres) y OR = 1,73, IC95%: 1,31-2,28 (mujeres). No obstante, contar con un bajo peso al nacer predispuso a contar con más masa grasa troncal solamente en mujeres (> percentil 85) % (OR = 1,40, IC95%: 1,03-1,91). En conclusión, en estos hombres y mujeres nacidos durante un período en el que la malnutrición fetal era prevalente, el peso al nacer mostró frecuentemente asociaciones no lineales complejas, con grasa corporal en la etapa adulta, resaltando la necesidad de intervenciones para prevenir el bajo y el alto peso al nacer durante el embarazo.

ABSTRACT

Birth weight is an important predictor of perinatal, infant, and preschool-age children morbimortality. However, information about indigenous children's birth weight is still scarce. This study aimed to analyze the birth weight of indigenous children based on data from the First National Survey of Indigenous People's Health and Nutrition, Brazil (2008-2009). This is the first study to address indigenous children's birth weight based on a nationwide representative sample. Mean birth weights and the respective standard deviations were calculated according to geopolitical region, sex, type of birth, and birthplace. The chi-square test was used to analyze differences in proportions, and Kruskal-Wallis and Mann-Whitney U tests in means, considering sample design and data normality. We found no records on birth weight in the researched documents for 26.7% of the 6,128 sampled children. The mean birth weight for the 3,994 children included in the analyses was 3,201g (standard deviation - SD ± 18.6g), regardless of sex, type of birth, and birthplace. The prevalence of low birth weight was 7.6% (n = 302) and was significantly higher among girls. Boys presented significantly higher mean birth weight than girls, regardless of the geopolitical region. Low birth weight was slightly less frequent among indigenous children when compared to Brazilian children in general. Our study indicates the need to improve prenatal care and the quality of consultation records for indigenous women as a strategy to promote safe pregnancy and childbirth.


O peso ao nascer é um importante preditor de morbimortalidade perinatal, infantil e pré-escolar. São escassas as informações sobre o peso ao nascer das crianças indígenas no Brasil. O estudo teve como objetivo analisar o peso ao nascer das crianças indígenas, com base nos dados do Primeiro Inquérito Nacional de Saúde e Nutrição dos Povos Indígenas, Brasil (2008-2009). Este é o primeiro estudo a avaliar o peso ao nascer de crianças indígenas com base em uma amostra nacional representativa. Foram calculadas as médias e desvios-padrão de acordo com macrorregião, sexo, tipo e parto e local do parto. Foram utilizados o teste de qui-quadrado para analisar as diferenças de proporções e os testes de Kruskal-Wallis e U de Mann-Whitney para diferenças nas médias, considerando o desenho amostral do estudo e a normalidade dos dados. Para 26,7% das 6.128 crianças da amostra, não foi possível localizar qualquer registro de peso ao nascer nos documentos consultados. Entre as 3.994 crianças incluídas nas análises, o peso médio ao nascer, independentemente de sexo, tipo de parto e local do parto, foi 3.201g (desvio padrão - DP ± 18,6g). A prevalência de baixo peso ao nascer foi 7,6% (n = 302), significativamente mais alta em meninas. Os meninos apresentaram peso médio ao nascer significativamente mais alto que as meninas, independentemente de região. A frequência de baixo peso ao nascer foi ligeiramente mais baixa que nas crianças brasileiras em geral. O estudo aponta para a necessidade de melhorar a assistência pré-natal e a qualidade dos registros das consultas das mulheres indígenas, como estratégia para promover a segurança na gravidez e no parto.

El objetivo de este estudio fue analizar el peso al nacer de los niños indígenas, basado en datos de la Primera Encuesta Nacional de Salud y Nutrición de los Pueblo Indígenas, Brasil (2008-2009). Se trata del primer estudio dirigido al peso al nacer de niños indígenas, basado en una muestra representativa nacionalmente. Las medias y las respectivas desviaciones estándar del peso al nacer se calcularon según la región geopolítica, sexo, tipo de nacimiento y localización del mismo. Se usó un test chi-cuadrado para analizar las diferencias en proporciones y las pruebas Kruskal-Wallis y de la U de Mann-Whitney para las diferencias en las medias, considerando el diseño de la muestra del estudio y normalidad de los datos. Para un 26,7% de los 6.128 niños incluidos en la muestra no fue posible localizar ningún registro de peso al nacer en los documentos investigados. De los 3.994 niños incluidos en el análisis, la media de peso al nacer, independiente del sexo, tipo de nacimiento, y lugar de nacimiento, fue 3.201g (desviación estándar - SD ± 18,6g). La prevalencia del bajo peso al nacer fue 7,6% (n = 302) y fue significativamente más alta entre niñas. Los niños presentaron significativamente una media más alta de peso al nacer que las niñas, independientemente de la región. La frecuencia del bajo peso al nacer fue ligeramente más baja que la observada en niños brasileños en general. Este estudio presenta aspectos que se necesitan mejorar en el cuidado prenatal y en la calidad de los registros de las consultas de mujeres indígenas, como una estrategia para promover un embarazo y parto seguros.

ABSTRACT

Introducción: diversos estudios han sugerido que el bajo y alto peso al nacer (PN) se asocian a obesidad (OB) y sobrepeso (SP) durante la infancia y la edad adulta. Objetivos: determinar la asociación entre PN y OB en escolares de 9 años de tres regiones de Argentina. Materiales y métodos: las medidas antropométricas y la presión arterial (PA) se tomaron en 1.131 escolares (505 masculinos) de 8,8±2,1 años de edad promedio, en tres regiones de Argentina durante el año 2019. Se interrogó, además, acerca del peso al nacer y el estilo de vida. Resultados: el 21,1% (239) de los niños presentaba SP (IMC>85 <95 percentilo según CDC) y el 21,8% (246) OB (IMC>95 percentilo). La prevalencia de PN bajo (<2.500 g) fue de fue de 6,2% (n=70) y de PN alto (>4.000 g) de 7,3% (n=82). El puntaje z-IMC de los niños de 9 años aumentaba significativamente con el aumento del PN: PN bajo (z-IMC=0,33), normal (z-IMC=0,72) y alto (z-IMC=1,12). En modelos de regresión logística múltiple se observó que el PN bajo se asoció inversamente a la OB (OR, 0.41 [IC del 95%: 0,19-0,92]), mientras que el PN alto se asoció directamente con la OB ajustado por edad y sexo (OR, 2.48 [95% IC 1,53-4,02]). Conclusiones: nuestros datos indican que el alto PN, pero no el bajo PN, se asocia con OB en niños en edad escolar de 9 años, mientras que el bajo PN está inversamente asociado con OB.


Introduction: several studies have suggested that low and high birth weight are associated with obesity (OB) and overweight (OW) during childhood and adulthood. Objectives: to determine the association between birth weight and OB in 9-year-old schoolchildren from three areas of Argentina. Materials and methods: anthropometric measurements and blood pressure (BP) were taken in 1.131 schoolchildren (505 males) of an average age of 8.8±2.1 years in three areas of Argentina during 2019. Mothers were asked about their children's birth weight and lifestyle. Results: 21.1% (239) of the children had OW (BMI>85 <95 percentile according to the CDC) and 21.8% (246) OB (BMI>95 percentile). The prevalence of low birth weight (<2.500 g) was 6.2% (n=70) and of high birth weight (>4.000 g) was 7.3% (n=82). The 9-year-old z-BMI score increased significantly with increasing birth weight: low birth weight (z-BMI=0.33), normal (z-BMI=0.72) and high (z-BMI=1.12). In multiple logistic regression models, it was found that low birth weight was inversely associated with OB (OR, 0.41 [95% CI: 0.19-0.92]), while high birth weight was directly associated with OB adjusted for age and sex (OR, 2.48 [95% CI 1.53-4.02]). Conclusions: our data indicate that high birth weight, but not low birth weight, is associated with OB in 9-year-old schoolchildren, while low birth weight is inversely associated with OB

ABSTRACT

Es innegable la necesidad de contar con curvas estándar de tamaño al nacer y crecimiento para evaluar y contribuir a orientar las acciones en la atención del neonato. Durante muchos años, se utilizaron las referencias de Lejarraga y Fustiñana, que fueron progresivamente reemplazadas por las de Fenton y Kim.Recientemente, el proyecto INTERGROWTH-21st construyó estándares de crecimiento prescriptivo para evaluar el tamaño al nacer desde las 33 semanas de edad gestacional, referencias para evaluar el tamaño al nacer desde las 24 a las 32,6 semanas de edad gestacional y curvas para el seguimiento longitudinal del crecimiento de recién nacidos pretérmino desde las 27 semanas de edad gestacional. Los Comités de Crecimiento y Desarrollo y de Estudios Feto-neonatales de la Sociedad Argentina de Pediatría, en conjunto con la Secretaría de Gobierno de Salud de la Nación, acordaron recomendar el reemplazo de las curvas de Fenton y Kim por las de INTERGROWTH-21st


It is unquestionable the need to have standards of size at birth and growth to evaluate and contribute to guide the actions in the care of the newborn. For many years the references of Lejarraga and Fustiñana were used, progressively replaced by those of Fenton and Kim. However, recently, the INTERGROWTH-21st project has developed prescriptive growth standards to evaluate the size at birth from 33 weeks of gestational age, references from 24 to 32.6 weeks of gestational age, and curves for postnatal growth from 27 weeks of gestational age onward. The Growth and Development and Neonatal Fetal Studies Committees of the Argentine Society of Pediatrics in conjunction with the Secretary of National Government of Health agreed to recommend the replacement of the Fenton and Kim curves with those of INTERGROWTH-21st.

ABSTRACT

Abstract Objectives: to identify trendand factors associated with adverse birth weight. Methods: cross-sectional design. The analysis uses the 2009-2015 Uruguay Perinatal Computer Systemdata on 303,625 newborns. Results: the prevalence of macrosomia (> 3,999g) has increased from 7.0% to 8.4%. The prevalence of low birth weight (LBW) (< 2,500g) decreased, standing at 6.6% in the last year. The factors that determines more possibilities of LBW were preeclampsia (OR = 4.80; CI95%= 4.57-5.05), inadequate controls (OR = 2.29; CI95%= 2.20-2.39), shorter duration of pregnancy (OR = 2.52; CI95%= 2.50-2.55), previous hypertension (OR = 2.11; CI95%= 1.96-2.27), hypertensive disease of pregnancy (OR = 1.82; CI95%= 1.74-1.90), low prematernal maternal weight (OR = 1.65; CI95%= 1.58-1.74). Macrosomia was associated with type 1 diabetes (OR = 2.21; CI95%= 1.86-2.61), Type 2 or Gestational (OR = 1.78; CI95%= 1.70-1.87), obesity maternal (OR = 2.33; CI95%= 2.24-2.43) and longer gestation duration (OR = 2.62; CI95%= 2.53-2.72). Conclusions: the LBW decreases while the macrosomia increases. The health and nutritional status of women at the beginning of pregnancy, pathologies of the last trimester, smoking, shorter duration of pregnancy and inadequate controls are associated with BPN. Overweight, obesity and metabolic diseases determine macrosomia.


Resumen Objetivos: identificar tendencia y factores asociados al peso al nacer adverso. Métodos: diseño transversal, se analizaron nacimientos entre 2009-2015. El análisis utilizó el Sistema Informático Perinatal de Uruguay, de 2009-2015, datos de 303.625 recién nacidos. Resultados: la prevalencia de macrosomía (>3.999g) aumentó de 7% a 8,4%. La prevalencia de bajo peso al nacer (BPN) (<2.500g) disminuyó situándose en 6,6% en el último año. Los factores que determinaron mayores posibilidades de BPN fueron preeclampsia (OR=4,80; IC95%= 4,57-5,05), inadecuados controles (OR = 2,29; IC95%= 2,20-2,39), menor duración de la gestación (OR = 2,52; IC95%= 2,50-2,55), hipertensión arterial previa (OR = 2,11; IC95%= 1,96-2,27), enfermedad hipertensiva del embarazo (OR = 1,82; IC95%= 1,74-1,90), bajo peso materno pregestacional (OR = 1,65; IC95%= 1,58-1,74). Macrosomía se asoció con diabetes tipo 1 (OR = 2,21; IC95%= 1,86-2,61), tipo 2 o Gestacional (OR = 1,78; IC95%= 1,70-1,87), obesidad materna (OR = 2,33; IC95%= 2,242,43) y duración de gestación (OR = 2,62; IC95%= 2,53-2,72). Conclusiones: existe una tendencia a disminución del BPNy aumento de la macrosomía. La salud y estado nutricional de la mujer al inicio de la gestación, patologías del último trimestre, tabaquismo, menor duración de la gestación e inadecuados controles se asocian a BPN. El sobrepeso, la obesidad y enfermedades metabólicas determinan macrosomía.

ABSTRACT

Abstract Objective: to investigate the prevalence and risk factors in newborns with congenital heart defects (CHD). Methods: this case-control study included 234,386 births from January 2006 to June 2013 that were evaluated and registered in the Latin-American Collaborative Study of Congenital Malformations (ECLAMC) methodology, establishing the Bogota Birth Defects Surveillance and Follow-up Program (BBDSFP). Results: 234,368 births were registered and 277 of them were identified to have a CHD. The most common defect among all was ventricular septal defect (13.7%) followed by atrial septal defect (10.1%). As main associations we obtained: having any type of pre-gestational diabetes mellitus had an increased risk for the development of CHD (OR 16.36 CI: 4.54-58.35). Low weight newborns (less than 2,500 g) (OR: 4.13 CI: 3.13-5.44) and a gestational age lower than 36 weeks (OR: 4.92 CI: 3-5.44) were also linked to malformations. Conclusions: women with diabetes mellitus represent a high-risk pregnancy group, more work is needed to educate diabetic women, so CHD can be prevented and the outcomes of their pregnancy can be improved. Appropriate glycemic control before and during pregnancy may reduce CHD.


Resumen Objetivos: investigar la prevalencia y los factores de riesgo en recién nacidos con cardiopatías congénitas. Métodos: este estudio caso control incluyó 234.386 nacimientos desde enero del 2006 hasta junio del 2013, los cuales fueron evaluados y registrados según la metodología del Estudio Colaborativo Latinoamericano de Malformaciones Congénitas (ECLAMC) estableciendo el programa de vigilancia de defectos congénitos de Bogotá. Resultados: de 234.368 pacientes fueron incluidos en el estudio, 277 fueron diagnosticados con cardiopatías congénitas. El defecto cardiaco más común fue la comunicación interventricular (13.7%) seguido por la comunicación interauricular (10.1%). Al evaluar los factores de riesgo se encontró que las madres con diabetes mellitus pregestacional tuvieron mayor riesgo de tener hijos con cardiopatías congénitas (OR 16.36 IC: 4.54-58.35) y que los pacientes con bajo peso al nacer (menor de 2.500 g) (OR: 4.13 IC: 3.13-5.44) y edad gestacional menor a 36 semanas (OR: 4.92 CI: 3-5.44) tenían mayor riesgo de ser diagnosticados con una cardiopatía congénita. Conclusiones: las pacientes diabéticas en embarazo tienen mayor riesgo de que sus hijos desarrollen una cardiopatía congénita. Por lo anterior se necesita realizar un mayor trabajo tanto de educación como de seguimiento a las mujeres diabéticas, para así prevenir cardiopatías congénitas y disminuir el resigo de sus embarazos.
