Fetal Macrosomia and Postpartum Hemorrhage in Latin American and Caribbean Region: Systematic Review and Meta-analysis / Macrossomia fetal e hemorragia pós-parto na região da América Latina e Caribe: Revisão sistemática e metanálise

Abstract Objective To determine the association between fetal macrosomia (FM) and postpartum hemorrhage (PPH) in Latin American and Caribbean (LAC) women. Data Sources Studies evaluating the association between FM and PPH (≥ 500 ml) and severe PPH (≥ 1,000 ml) until November 4, 2021, indexed in CINHAL, Scopus, Embase, Cochrane Library, MEDLINE, LILACS, and SciELO. Selection of Studies Inclusion criteria were cohort and case-control studies that provided the number of PPH and FM cases. Exclusion criteria were studies lacking information about the number of cases, with a population of women who were not from LAC; published in a language other than English, Spanish, or Portuguese, and with a different design. Data Collection Data extraction was performed independently by two authors, and discrepancies were resolved with a third author. Data regarding FM and PPH cases were retrieved. Data Synthesis Of the 1,044 articles evaluated, 5 studies were included, from 6 different countries: Argentina and Uruguay (multi-country), West Indies, Antigua and Barbuda, French Guyana, and Suriname. The pooled odds ratio (OR) for FM and PPH in the meta-analysis (five studies) was 2.10 (95% confidence interval [CI]: 1.79-2.47; I2: 0%), with estimates within this 95% CI in the sensitivity analysis. The combined OR for severe PPH (3 studies) was 1.61 (95% CI: 0.40-6.48; I2: 91.89%), showing high heterogeneity. Conclusion There was a positive association between FM and PPH in the LAC, increasing the risk of the presence of this event 2-fold. The high heterogeneity of the studies that measured severe PPH does not allow drawing conclusions about the estimates obtained.

Fontes de dados Estudos avaliando a associação entre FM e HPP (≥ 500 ml) e HPP grave (≥ 1.000 ml) até 4 de novembro de 2021, indexados no CINHAL, Scopus, Embase, Biblioteca Cochrane, MEDLINE, LILACS e SciELO. Seleção de estudos Os critérios de inclusão foram estudos de corte e caso-controle que forneceram o número de casos de HPP e FM. Os critérios de exclusão foram estudos sem informação sobre o número de casos, com uma população de mulheres que não eram da ALC; publicado em um idioma diferente do inglês, espanhol ou português e com um design diferente. Coleta de dados A extração de dados foi realizada independentemente por dois autores, as discrepâncias foram resolvidas com um terceiro autor. Os dados relativos aos casos de FM e HPP foram recuperados. Síntese dos dados Dos 1.044 artigos avaliados, foram incluídos 5 estudos, de 6 países diferentes: Argentina e Uruguai (multipaíses), Índias Ocidentais, Antígua e Barbuda, Guiana Francesa e Suriname. O odds ratio agrupado (OR) para FM e HPP na meta-análise (cinco estudos) foi de 2,10 (intervalo de confiança de 95% [IC]: 1,79-2,47; I2: 0%), com estimativas dentro deste IC de 95% no análise sensitiva. O OR combinado para HPP grave (3 estudos) foi de 1,61 (95% CI: 0.40-6.48; I2: 91.89%), mostrando alta heterogeneidade. Conclusão Houve associação positiva entre FM e HPP na ALC, aumentando em 2 vezes o risco da presença desse evento. A alta heterogeneidade dos estudos que mediram a HPP grave não permite tirar conclusões sobre as estimativas obtidas.

Prontidão para via oral, aleitamento materno e diabetes mellitus gestacional: estudo caso-controle / Readiness for way oral, breastfeeding and gestational diabetes mellitus: a case-control study

RESUMO Objetivo verificar a prontidão para via oral e aleitamento materno em recém-nascidos de mães diagnosticadas com diabetes mellitus gestacional (DMG). Métodos estudo observacional, analítico, quantitativo, do tipo caso-controle. Para avaliação da sucção não nutritiva, foi utilizado o Protocolo de Prontidão do Prematuro para Início da Alimentação por Via Oral - POFRAS e, para avaliação do desempenho em seio materno, o Protocolo de Acompanhamento Fonoaudiológico - Aleitamento Materno. A amostra foi estratificada em dois grupos, sendo o grupo experimental composto por recém-nascidos de mães diagnosticadas com DMG e o grupo-controle, por recém-nascidos de mães hígidas. Para a análise estatística, foram utilizados os testes Mann-Whitney, Shapiro Wilk e t de Student. Resultados a amostra total foi composta por 46 recém-nascidos, sendo 21 do grupo experimental e 25 do grupo-controle. Observou-se p<0,05 na comparação entre os grupos nas seguintes variáveis: oscilação do estado de consciência, hipotonia global, reflexo de procura débil, menos de cinco sucções por pausa na avaliação da sucção não nutritiva, pega em seio, adormecimento após iniciar sucção e posicionamento mãe-bebê. Conclusão recém-nascidos de mães diagnosticadas com DMG apresentaram maior dificuldade na prontidão para via oral e na prática do aleitamento materno nas primeiras 72 horas de vida, comparados aos filhos de mães hígidas.

ABSTRACT Purpose to verify the readiness for oral feeding and breastfeeding in newborns of mothers diagnosed with gestational diabetes mellitus (GDM). Methods observational, analytical, quantitative case-control study. For the evaluation of non-nutritive sucking, the PROFAS protocol was used and for the evaluation of performance at the mother's breast, the protocol of Speech Therapy - Breastfeeding. The sample was stratified into two groups, the experimental group, composed of newborns of mothers diagnosed with GDM, and the control group, with newborns of healthy mothers. For statistical analysis, the Mann-Whitney, Shapiro Wilk and Student's t tests were used. Results the total sample consisted of 46 newborns, 21 from the experimental group and 25 from the control group. P<0.05 was observed in the comparison between the groups in the variables: oscillation in the state of consciousness, global hypotonia, weak search reflex, less than five suctions per pause in the assessment of non-nutritive sucking, holding on to the breast, falling asleep after starting suction and mother-infant positioning. Conclusion newborns of mothers diagnosed with GDM had greater difficulty in readiness for oral feeding and in the practice of breastfeeding in the first 72 hours of life, compared to children of healthy mothers.

Weekly gestational weight gain in women with obesity and its association with risk of macrosomia / 中华围产医学杂志

Objective:To explore the characteristics of weekly gestational weight gain (GWG) in women with obesity and its correlation with the risk of macrosomia.Methods:Clinical data of women with singleton pregnancy and pre-pregnancy body mass index (PPBMI) ≥28 kg/m 2 were retrospectively analyzed, from January 2014 to December 2019, in Beijing Obstetrics and Gynecology Hospital, Capital Medical University (Beijing Maternal and Child Health Care Hospital). The participants were divided into three groups based on their PPBMI: group A (28-<30 kg/m 2), group B (30-<32 kg/m 2), and group C (≥32 kg/m 2). The study compared the characteristics of GWG among the three groups, explored the correlation between the weekly weight gain during each gestational stage and the risk of macrosomia, and discussed the impacts of the GWG pattern in women with different PPBMI on the risk of macrosomia. Chi-square (or Fisher's exact), Kruskal-Wallis, and Mann-Whitney U tests were performed for statistical analysis. Multivariate logistic regression was used to analyze the impact of weekly weight gain in specific gestational stages on macrosomia. Results:(1) A total of 2 046 participants were included in the study, with 982 in group A, 588 in group B, and 476 in group C. For all of the 2 046 cases, the median PPBMI was 30.1 kg/m 2 (29.0-31.9 kg/m 2), GWG was 10.5 kg (7.3-14.0 kg), and neonatal birth weight was 3 520 g (3 215-3 816 g) with 60 (2.9%) ≥4 500 g, and the biggest baby weighed 5 580 g. Out of the births analyzed, macrosomia occurred in 318 cases (15.5%). (2) Among the three groups (A, B and C), the differences in maternal age [32.0 years (29.0-35.0 years), 32.0 years (29.0-35.0 years) and 32.0 years (29.0-34.0 years), H=6.58] and women with a history of type 2 diabetes mellitus [0.9% (9/982), 0.3% (2/588) and 1.9% (9/476), χ2=6.61] were statistically significant (all P<0.05). (3) The weekly weight gain in each group exhibited a gradual upward trend before 20-24 weeks, reached a plateau at 24-32 weeks, peaked at 32-36 weeks, and subsequently declined. The weekly weight gain of group A in the pre-pregnancy to 14 weeks [0.14 kg/week (0.00-0.25 kg/week)], 14 to 20 weeks [0.25 kg/week (0.17-0.42 kg/week)], and 20 to 24 weeks [0.38 kg/week (0.25-0.63 kg/week)] were higher than those of group B [0.07 kg/week (－0.03-0.21 kg/week), 0.25 kg/week (0.10-0.42 kg/week), and 0.38 kg/week (0.22-0.60 kg/week)], respectively ( Z value was－3.73,－2.16, and－2.01, all P<0.05). Likewise, the weekly weight gain of group B in the above three stages were all higher than those of group C [0.07 kg/week (－0.10-0.21 kg/week), 0.17 kg/week (0.05-0.33 kg/week), and 0.25 kg/week (0.08-0.50 kg/week)], respectively ( Z value was－2.55,－3.28, and－3.25, all P<0.05). (4) The risk of macrosomia increased with the weekly weight gain in specific gestational stages in different PPBMI groups. In group A, the stages correlated with increased risk were 14-20 weeks [adjusted odd ratio ( aOR)=2.669, 95% CI: 1.378-5.169] and 20-24 weeks ( aOR=1.764, 95% CI: 1.143-2.723), while the stages were 20-24 weeks ( aOR=2.149, 95% CI: 1.156-3.996) and 36 weeks until delivery ( aOR=1.888, 95% CI: 1.268-2.810) in group B, and pre-pregnancy to 14 weeks ( aOR=3.515, 95% CI: 1.158-10.665) and 14-20 weeks ( aOR=3.021, 95% CI: 1.058-8.628) in group C (all P<0.05). The risk of macrosomia increased when the weekly weight gain of both risk-related stages in group A ( aOR=2.255, 95% CI: 1.029-4.940) ≥50th percentile, and group B ( aOR=4.399, 95% CI: 1.017-19.023) ≥75th percentile, and for group C ( aOR=3.404, 95% CI: 1.004-11.543) when the weekly weight gain above 25th percentile (all P<0.05). Conclusions:Weekly GWG demonstrates an observable gradual acceleration pattern in women with obesity. Therefore, clinical attention should be directed towards monitoring fluctuations in the weekly weight gain in this population, as excessive weekly weight gain before 24 gestational weeks is associated with an elevated risk of macrosomia.

Effect of anesthesia type on outcome measures in cesarean section in the presence of fetal macrosomia

SUMMARY OBJECTIVE: The aim of this study was to compare the effects of general and spinal anesthesia on maternal and neonatal outcomes during cesarean section in pregnancies with macrosomia. METHODS: This retrospective cohort study included 1043 patients who delivered by cesarean section between May 2018 and December 2021 and had a baby born with a birth weight of 4000 g or greater. Maternal and neonatal outcomes were compared according to the type of anesthesia performed in the spinal anesthesia group (n=903; 86.6%) and general anesthesia group (n=140; 13.4%). The Apgar score was categorized into <7 and ≥7. RESULTS: Neonates with an Apgar score of <7 at the first minute (11.4 vs. 0.4%; p<0.001) and the fifth minute (2.9 vs. 0.3%; p=0.004) were significantly higher in the general anesthesia group. The preoperative and postoperative hematocrit difference was significantly lower in patients who received spinal anesthesia than those who received general anesthesia [2 (1.1-3.1) vs. 4.05 (2.8-5.35); p<0.001]. The number of patients transfused was higher in the general anesthesia group (9.3 vs. 2.7%; p<0.001). In the regression model, general anesthesia, birth weight, and emergency conditions were significant independent factors related to the preoperative and postoperative hematocrit decrease (p<0.001, p=0.005, and p=0.034, respectively). CONCLUSIONS: Apgar scores of <7 at the first and fifth minutes are higher in macrosomic neonates who received general anesthesia than in neonates who received spinal anesthesia. Performing cesarean section under general anesthesia in mothers of macrosomic neonates results in a greater decrease in hematocrit value and a greater need for blood transfusion than under spinal anesthesia.

Variables maternas relacionadas con la condición trófica al nacer / Maternal variables related to the trophic condition at birth

RESUMEN Introducción: El crecimiento y desarrollo prenatal tiene su expresión en el peso al nacer, que adquiere gran importancia por su relación con la morbilidad y mortalidad en cualquier etapa de la vida. Objetivo: Identificar las asociaciones de variables maternas con la condición trófica del recién nacido. Métodos: Se realizó un estudio descriptivo, en tres áreas de salud del municipio Santa Clara, en el periodo comprendido de enero 2013 a diciembre 2020. De una población de 6035 recién nacidos se seleccionó una muestra aleatoria de 2454. De los libros de genética se obtuvo la información de variables maternas y del neonato. Se aplicaron las pruebas no paramétricas de independencia basada en la distribución chi cuadrado y Kruskal Wallis en el análisis estadístico. Resultados: A excepción de la edad, las variables estudiadas mostraron relación con la condición trófica al nacer. El estado nutricional deficiente fue más frecuente en nacimientos pequeños y el obeso en los grandes. En nacimientos grandes se observó mayores porcentajes de gestantes con riesgo de diabetes gestacional. Los trastornos hipertensivos, la anemia, la infección del tracto urinario, la sepsis vaginal y el hábito de fumar se presentaron en mayores porcentajes en gestantes cuyos recién nacidos fueron pequeños. Conclusiones: De las variables estudiadas el riesgo de diabetes gestacional y los trastornos hipertensivos mostraron la mayor fuerza de asociación con la condición trófica al nacer.

ABSTRACT Introduction: prenatal growth and development have their expression in birth weight, which acquires great importance due to its relationship with morbidity and mortality at any stage of life. Objective: to identify the associations of maternal variables with the trophic condition of the newborn. Methods: a descriptive study was carried out in three health areas from Santa Clara municipality between January 2013 and December 2020. A random sample of 2,454 was selected from a population of 6,035 newborns. Information on maternal and newborn variables was obtained. Non-parametric tests of independence based on the Chi-square distribution and Kruskal Wallis were applied in the statistical analysis. Results: the variables studied showed a relationship with the trophic condition at birth, except for age. Poor nutritional status was more frequent in small births and obesity in large ones. In large births, higher percentages of pregnant women at risk of gestational diabetes were observed. Hypertensive disorders, anemia, urinary tract infection, vaginal sepsis and smoking were present in higher percentages in pregnant women whose newborns were small. Conclusions: from the studied variables, the risk of gestational diabetes and hypertensive disorders showed the strongest association with the trophic status at birth.

Incidencia de recién nacidos grandes para la edad gestacional y su asociación con diabetes mellitus gestacional y obesidad maternas. Estudio de cohorte en un hospital de Buenos Aires / Incidence of large-for-gestational-age newborns and its association with maternal gestational diabetes mellitus and obesity. Cohort study in a hospital in Buenos Aires

Resumen Introducción: existen dos términos para describir el crecimiento fetal excesivo: "grande para la edad gestacional" (GEG) y "macrosomía". GEG generalmente implica un peso al nacer superior al percentil 90 para una edad gestacional determinada. Objetivos: estimar la incidencia de recién nacidos GEG, y evaluar si la obesidad y la diabetes mellitus gestacional (DMG) son factores asociados. Materiales y métodos: estudio de cohorte retrospectivo de embarazadas -con y sin DMG- y sus recién nacidos vivos entre 2015 y 2018, evaluadas en el Hospital Italiano de la Ciudad Autónoma de Buenos Aires. La incidencia de recién nacidos GEG y de macrosomía se presentó como porcentajes e intervalos de confianza del 95% (IC 95%), así como sus complicaciones. Se utilizó regresión logística múltiple para evaluar si la DMG y la obesidad eran factores asociados a recién nacidos GEG. Resultados: la incidencia de GEG fue del 15,9% (IC 95%; 14,117,9) y de macrosomía del 6,7% (IC 95%; 5,5-8,1). La incidencia de recién nacidos GEG fue mayor en las mujeres con DMG y obesidad. La obesidad representó per se un mayor riesgo con y sin asociación con DMG. La obesidad, en presencia de DMG, incrementa la chance de recién nacidos GEG comparada con las mujeres sin DMG y sin obesidad (OR 2,41; p<0,001). Conclusiones: la DM y la obesidad materna incrementan el riesgo de GEG. Es importante implementar medidas preventivas e intervenciones en las mujeres en edad fértil con el objetivo de promover la salud de la madre y de su descendencia.

Abstract Introduction:two terms are used to describe excessive fetal growth: "large for gestational age" (LGA) and "macrosomia". LGA generally implies a birth weight greater than the 90th percentile for a given gestational age. Objectives: to estimate the incidence of LGA newborns and to assess whether obesity and gestational diabetes mellitus (GDM) are associated factors. Materials and methods: retrospective cohort study of pregnant women with and without GDM and their live newborns between 2015-2018 evaluated at the Italian Hospital in the City of Buenos Aires, Argentina. The incidence of LGA and macrosomia newborns is presented as percentages and 95% confidence intervals (95% CI), as well as their complications. Multiple logistic regression was used to assess whether GDM and obesity are factors associated with LGA newborns. Results: the incidence of LGA was 15.9% (IC 95%; 14.1-17.9) and of macrosomia 6.7% (IC 95%; 5.5-8.1). The incidence of LGA newborns was higher in women with GDM and obesity. Obesity represented a higher risk per se with and without association with GDM. Obesity, in the presence of GDM, increases the chance of LGA newborns compared to women with GDM and without obesity (OR 2.41; p<0.001). Conclusions:diabetes and maternal obesity increase the risk of LGA. It is important to implement preventive measures and interventions on women of childbearing age with the aim of promoting the health of the mother and her offspring.

Resultados maternos perinatales vinculados a la macrosomía fetal / Perinatal maternal outcomes linked to fetal macrosomia

RESUMEN Introducción: la macrosomía fetal ha estado asociada a una alta tasa de morbilidad y mortalidad materna y perinatal. Objetivo: identificar las peculiaridades maternas asociadas a un feto macrosómico en el Hospital Abel Santamaría, entre el 2018 y 2020. Métodos: se realizó un estudio observacional, transversal y retrospectivo en el Hospital Abel Santamaría, entre el 2018 y 2020. El universo estuvo conformado por todos los neonatos nacidos en el período antedicho, mientras que la muestra se formó por un grupo de fetos macrosómicos escogidos según la fórmula muestral y dos neonatos con peso entre 3 000 y 3 500 gramos (grupo control); los resultados se analizaron por diferentes métodos estadísticos, además se utilizó el Chi cuadrado con nivel de significación de p < 0,05 y el Odds Ratio. Resultados: se obtuvo que los fetos macrosómicos tuvieron relación altamente significativa con la edad gestacional de 40 a 41,6 semanas, y la cesárea; asimismo, el sexo masculino, el Apgar bajo al minuto y los cinco minutos se asociaron al macrofeto. Hubo mayor número de complicaciones maternas y neonatales en el grupo estudio. Conclusiones: la macrosomía fetal es un evento obstétrico que se asocia altamente con resultados maternos y perinatales desfavorables.

ABSTRACT Introduction: fetal macrosomia has been associated with a high rate of maternal and perinatal morbidity and mortality. Objective: to identify the maternal peculiarities that associated with a macrosomic fetus in the Abel Santamaría Hospital, between 2018 and 2020. Methods: an observational, cross-sectional and retrospective study was conducted at the Abel Santamaría Hospital, between 2018 and 2020; the universe was made up of all the neonates born in the aforementioned period, while the sample was formed by a group of macrosomic fetuses chosen according to the sample formula and two neonates weighing between 3000 and 3500 grams (control group); the results were analyzed by different statistical methods, in addition Chi-square with significance level of p < 0,05 and Odds Ratio were used. Results: macrosomic fetuses had a highly significant relationship with gestational age from 40 to 41,6 weeks, and cesarean section; likewise, male sex, low Apgar at one minute and five minutes were associated with macrosomia. There were more maternal and neonatal complications in the study group. Conclusions: fetal macrosomia is an obstetric event that is highly associated with unfavorable maternal and perinatal outcomes.

Background: Maternal obesity, a growing global public health problem, is related to neonatal morbidity and mortality. The objective was to determine adverse neonatal outcomes according to degrees of pregestational obesity. Material and method: Analytical study, retrospective cohort, in pregnant women with a single pregnancy, delivery attended at the Hipolito Unanue hospital in Tacna, Peru, during 2010 to 2019, with live newborns, the cases were 5935 mothers with pre-pregnancy body mass index from 30 Kg/m2 to more, grouped in grade I (BMI 30-34.9 Kg/m2), II (BMI 35-39.9 Kg/m2) and III (BMI>40 Kg/m2), the control mothers with a BMI of 18-24.9 Kg/m2. Pregnant women with diabetes mellitus, preeclampsia, eclampsia and congenital anomalies were excluded. Crude Relative Risk (RR) was used, adjusted for maternal age, schooling and parity, with a 95% confidence interval. Results: The frequency of pre-pregnancy obesity was 14.3% grade I, 3.8% grade II and 1% grade III. The associated neonatal outcomes were: birth weight >4000 grams, for grade I obesity (RRa: 1.9; 95% CI: 1.7-2.0), grade II (RRa: 2.0; 95% CI: 1.8-2.3) and grade III (RRa: 2.1; CI95%: 1.7-2.5); large for gestational age for grade I (RRa: 1.6; 95% CI: 1.4-1.7), grade II (RRa: 1.7; 95% CI: 1.6-1.9) and grade III (RRa: 1.8; CI95%: 1.4-2.1). Conclusions: There is an increased risk of fetal macrosomia and large for gestational age with a higher degree of maternal pregestational obesity.

Altura uterina versus ecografía obstétrica para detectar macrosomía fetal. Hospital San Juan de Kimbiri, Perú

RESUMEN Fundamento Aunque la ecografía obstétrica es ampliamente utilizada en los niveles primario y secundario de salud para la detección de macrosomía fetal, la altura uterina también puede resultar útil, sobre todo, en contextos sanitarios desprovistos de equipamiento tecnológico. Objetivo determinar la correlación entre altura uterina versus ecografía obstétrica y el diagnóstico de macrosomía fetal. Métodos estudio descriptivo, correlacional, en madres no diabéticas de partos a término con neonatos macrosómicos, realizado en un hospital público del Valle de los ríos Apurímac, Ene y Mantaro, Perú. Las variables del estudio: edad materna, índice de masa corporal pregestacional, número de embarazos, edad gestacional al parto, y vía del parto. Se emplearon los coeficientes de correlación Rho de Spearman, y Pearson, ambos con intervalos de confianza al 95 % y error del 5 %. Resultados la estimación del peso fetal y la macrosomía se correlacionaron con la altura uterina (R Pearson 0,05). Entre las características maternas asociadas a neonatos macrosómicos, se hallaron la obesidad pregestacional (Rho = 0,009) y la condición de multigesta (Rho = 0,04). La estimación del peso fetal mayor a 4000 g tuvo mayor porcentaje de acierto (26,3 %) por ecografía obstétrica. Conclusión la ecografía obstétrica mostró mayor correlación que la altura uterina con el diagnóstico de macrosomía fetal.

ABSTRACT Background Although obstetric ultrasound is widely used at primary and secondary health levels for the detection of fetal macrosomia, uterine height can also be useful, especially in health contexts lacking technological equipment. Objective to determine the correlation between uterine height versus obstetric ultrasound and the diagnosis of fetal macrosomia. Methods descriptive, correlational study in non-diabetic mothers of full-term deliveries with macrosomic neonates, carried out in a public hospital in the Valley of the Apurímac, Ene and Mantaro rivers, Peru. The study variables: maternal age, pre-pregnancy body mass index, number of pregnancies, gestational age at delivery, and route of delivery. Spearman's Rho and Pearson's correlation coefficients were used, both with 95% confidence intervals and 5% error. Results Fetal weight estimation and macrosomia correlated with uterine height (Pearson's R 0.05). Among the maternal characteristics associated with macrosomic neonates, pregestational obesity (Rho = 0.009) and multigestational condition (Rho = 0.04) were found. The estimation of fetal weight greater than 4000 g had a higher percentage of success (26.3%) by obstetric ultrasound. Conclusion obstetric ultrasound showed a higher correlation than uterine height with the diagnosis of fetal macrosomia.

Macrosomía fetal y factores de riesgo asociados en la provincia Camagüey

Introducción: La macrosomía fetal, de manera tradicional, ha sido definida por un peso arbitrario al nacer; la misma, ya sea definida por un límite de peso o grande para la edad gestacional, se asocia con numerosas complicaciones perinatales y maternas. Objetivo: Describir los factores de riesgo asociados a la macrosomía fetal en los partos del Hospital Universitario Ginecobstétrico Provincial Ana Betancourt de Mora durante el año 2019. Métodos: Se realizó un estudio observacional descriptivo de corte transversal. El universo quedó constituido por la totalidad de gestantes que tuvieron recién nacidos con peso al nacimiento mayor o igual a 4 000 gramos, el cual ascendió a 526 gestantes. Se utilizó estadística descriptiva. Se calculó media y desviación estándar a las variables cuantitativas. Resultados: Las gestantes estudiadas tenían una media de edad de 27,86 años y un IMC a la captación como promedio de 26,77 con un valor medio de ganancia de peso de 13,68 Kg. Entre los 26 y 35 años hubo 290 gestantes con recién nacidos macrosómicos, respecto a la paridad las que paren sin experiencia de este reunió a 222 grávidas. En las embarazadas catalogadas de sobrepeso con ganancia de 10 a 15 kg se reúnen 104 de los recién nacidos macrosómicos. Respecto al tipo de parto la cesárea representó el 61,4 %. Se observó en 40 gestantes la presencia de diabetes gestacional o pregestacional y preeclampsia respectivamente. Conclusiones: La ganancia excesiva de peso en gestantes con evaluación nutricional de sobrepeso u obesas tuvo la mayor incidencia en la génesis de la macrosomía en los recién nacidos.

Introduction: Fetal macrosomia has traditionally been defined by an arbitrary birth weight. Fetal macrosomia, whether defined by borderline weight or large for gestational age, is associated with numerous perinatal and maternal complications. Objective: To describe the risk factors associated with fetal macrosomia in deliveries at Ana Betancourt de Mora Provincial Gyneco-Obstetric University Hospital during 2019. Methods: A cross-sectional descriptive observational study was carried out. The study universe was made up of all pregnant women who had newborns with a birth weight greater than or equal to 4 000 grams, which amounted to 526 pregnant women. Descriptive statistics were used. Average and standard deviation were calculated for the quantitative variables. Results: The studied pregnant women had an average age of 27.86 years and an average BMI at uptake of 26.77 with an average value of weight gain of 13.68 Kg. Between 26 and 35 years there were 290 pregnant women with newborn macrosomic births, with respect to parity those who give birth without experience of this brought together 222 gravid women. In pregnant women classified as overweight with a gain of 10 to 15 kg, 104 of the macrosomic newborns are gathered. Regarding the type of delivery, cesarean section represented 61.4%. The presence of gestational or pregestational diabetes and preeclampsia, respectively, was observed in 40 pregnant women. Conclusions: The excessive weight gain in pregnant women with nutritional evaluation of overweight or obese were those that had the highest incidence in the genesis of macrosomia in newborns.

Efecto del comportamiento del peso materno en el peso del neonato / Effect of the behavior of maternal weight on the weight of the newborn. Introduction

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)

Malformaciones esqueléticas y alteraciones del crecimiento en fetos de ratas con diabetes moderada / Skeletal malformations and growth disturbances in fetuses of mild diabetic rats

Resumen Introducción. En la actualidad, la diabetes mellitus representa una de las condiciones médicas que complica el embarazo con mayor frecuencia, lo que afecta el crecimiento y el desarrollo fetal. Objetivo. Determinar las malformaciones esqueléticas y alteraciones en el crecimiento en fetos de ratas Wistar diabéticas. Materiales y métodos. Se utilizó un modelo de diabetes moderada inducida neonatalmente con estreptozotocina (STZ 100 mg/kg de peso corporal, por vía subcutánea) en ratas Wistar. En la adultez, las ratas sanas y diabéticas se aparearon con machos sanos de la misma edad y cepa. El día 20 de gestación se practicó la cesárea bajo anestesia. Se extrajeron los fetos, se pesaron y clasificaron como pequeños (PAG), adecuados (AEG) o grandes (GEG) para la edad gestacional. Los fetos seleccionados se procesaron para el análisis de anomalías esqueléticas y sitios de osificación. Resultados. En la descendencia de las ratas diabéticas, hubo un mayor porcentaje de fetos clasificados como pequeños o grandes y un menor porcentaje de fetos con peso adecuado; el promedio de peso fetal fue menor y había menos sitios de osificación. Se observaron alteraciones en la osificación de cráneo, esternón, columna vertebral, costillas y extremidades anteriores y posteriores; y también, hubo una correlación directa entre el peso y el grado de osificación fetal. Hubo malformaciones congénitas asociadas con la fusión y bifurcación de las costillas, así como cambios indicativos de hidrocefalia, como la forma de domo del cráneo, una amplia distancia entre los parietales y la anchura de las fontanelas anterior y posterior. Conclusión. La diabetes moderada durante la gestación altera el crecimiento y el desarrollo fetal, que se ve afectado tanto por macrosomía y la restricción del crecimiento intrauterino como por malformaciones esqueléticas.

Abstract Introduction: Currently, diabetes mellitus represents one of the medical conditions that more frequently complicates pregnancy affecting the fetus's growth and development. Objective: To determine the skeletal malformations and growth alterations in fetuses of diabetic Wistar rats. Materials and methods: We used a neonatally streptozotocin-induced mild diabetes model (STZ 100 mg/kg body weight - subcutaneously) in Wistar rats. In adulthood, healthy and diabetic rats were mated with healthy males of the same age and strain. On day 20 of gestation, a cesarean was performed under anesthesia. Fetuses were removed, weighed, and classified as small (SPA), adequate (APA), and large (LPA) for the gestational age. Selected fetuses were processed for skeletal anomaly and ossification sites analysis. Results: In the offspring of diabetic rats, there was a higher percentage of fetuses classified as small or large and a lower percentage of fetuses with adequate weight; the fetal weight mean was lower and there were fewer sites of ossification. Alterations were observed in the ossification of the skull, sternum, spine, ribs and fore and hind limbs; and also, there was a direct correlation between fetal weight and ossification degree There were congenital malformations associated with fusion and bifurcation of the ribs, as well as changes indicative of hydrocephaly, such as the dome shape of the skull, a wide distance between parietals, and the width of the anterior and posterior fontanels. Conclusion: Moderate diabetes during pregnancy alters fetal growth and development with macrosomia and intrauterine growth restriction, as well as skeletal malformations.

Factores maternos asociados al peso del recién nacido en una IPS de Medellín, Colombia, 2018 / Maternal Factors Associated with Newborn Weight in a IPS in Medellin, Colombia, 2018

Resumen Antecedentes: la variabilidad en el peso del recién nacido, ya sea como bajo peso o macrosomía, puede ocasionar morbimortalidad infantil y materna, además de ser un predictor del estado de salud a lo largo de la vida. Objetivo: determinar factores sociodemográficos, antecedentes patológicos, exposición a sustancias psicoactivas, actividad física y características alimentarias de la madre relacionados con el peso de recién nacidos en una IPS de Medellín, Colombia, en 2018. Materiales y métodos: estudio de cohorte con información de madres seguidas hasta el nacimiento de los bebés. Resultados: la edad promedio de las madres fue de 24±6 años, el peso promedio del recién nacido fue de 3150 g. Embarazo previo, consumo de lácteos y derivados, consumo de proteínas y de suplementos dietarios fueron factores presentes en madres de recién nacidos con mayor peso. Haber fumado alguna vez en la vida, antecedente de preeclampsia, parto previo, aborto en el último embarazo y consumo de alimentos ultraprocesados se presentaron en madres de recién nacidos con menor peso. Conclusiones: se recomienda a las gestantes limitar el consumo de alimentos ultraprocesados, supervisar el consumo de lácteos y derivados, proteínas y suplementos dietarios en madres con embarazos previos, antecedente de preeclampsia, abortos o hábitos como haber fumado.

Abstract Background: The variability in newborn birthweight, whether low birth weight or macrosomia, can contribute to maternal and infant morbidity and mortality as well as be a predictor of lifelong health. Objective: Determine socio-demographic factors, pathologic history, exposure to psychoactive substances, physical activity levels, and maternal diet as related to birth weight in newborns an in IPS in Medellin, Colombia 2018. Materials and Methods: Cohort study using maternal information obtained from following a sample of mothers of newborns until their infant's birth. Results: Average age of the mothers was 24±6 years and average newborn birthweight was 3150g. Previous pregnancies, consumption of dairy products, intake of protein, and use of dietary supplements were factors present in mothers of newborns with higher birthweight. Having ever smoked, history of preeclampsia, previous delivery, abortion in previous pregnancy, and intake of ultra-high processed foods (UHPF) were factors found among mothers whose infants had lower birthweight. Conclusions: It is recommended that pregnant women limit intake of highly processed foods, supervise their intake of dairy products, protein and dietary supplements in women who have had previous pregnancies, history of preeclampsia, abortions, or who have ever smoked.

Factores maternos y ganancia de peso en un grupo de gestantes con recién nacidos macrosómicos / Maternal Factors and Weight Gain in a Group of Pregnant Women with Macrosomic Newborns

Resumen Antecedentes: la excesiva ganancia de peso contribuye al riesgo de diabetes gestacional y sobrecrecimiento fetal. Objetivo: explorar el efecto de algunos factores sociodemográficos, gestacionales y antropométricos sobre la ganancia de peso durante la gestación en un grupo de mujeres con recién nacidos macrosómicos, atendidas en una institución de segundo nivel del departamento de Antioquia, Colombia, entre 2010 y 2017. Materiales y métodos: se realizó un estudio transversal retrospectivo con historias clínicas prenatales de 61 mujeres que tuvieron recién nacidos macrosómicos. La variable de interés fue la ganancia de peso. Para la asociación de los aspectos sociodemográficos y gestacionales con la ganancia de peso, se aplicó la prueba t de Student y la magnitud del efecto con la medida g de Hedges. Se aplicó un modelo de regresión lineal múltiple ajustado para el análisis multivariado. Resultados: se hallaron diferencias estadísticamente significativas según edad materna, IMC pregestacional, estatura materna e interconsulta a nutrición. El tamaño del efecto sobre el aumento de peso en el embarazo para cada una de estas variables fue significativo. El IMC pregestacional (p<0,001; IC95 % -7,28; -2,67) y la estatura materna (p<0,05 IC95 % 0,88; 5,87) explican el 27 % de la variabilidad de la ganancia de peso. Conclusión: factores como edad materna menor a 35 años, IMC pregestacional, estatura materna y ausencia de atención nutricional pueden repercutir en ganancias de peso por encima de lo recomendado.

Abstract Background: Excessive weight gain contributes to the risk of gestational diabetes and fetal overgrowth. Objective: to explore the effect of some sociodemographic, gestational and anthropometric factors on weight gain during pregnancy, in a group of women with macrosomic newborns, treated at a second-level institution in the department of Antioquia, between 2010 and 2017. Materials and Methods: A descriptive cross-sectional study was conducted with prenatal medical records of 61 women with macrosomic newborns. The variable of interest was weight gain. For the relationship of the sociodemographic and gestational aspects with the weight gain, the t-Student test was applied and the magnitude of the effect with the Hedges g measure. A multiple linear regression model adjusted was applied for multivariate analysis. Results: Statistically significant differences were found in maternal age, pregestational body mass index, maternal height, and nutrition consultation. The effect size on weight gain in pregnancy for each of these variables was significant. Pregestational body mass index (p<0.001, 95% CI -7.28; -2.67) and maternal height (P<0.05 95% CI 0.88; 5.87) explain 27% of the variability of weight gain. Conclusion: factors such as maternal age less than 35 years, pregestational body mass index, maternal height and lack of nutritional care, can have an impact on weight gains above the recommendations.

Factores de riesgo materno asociados con macrosomía fetal en el Hospital de Clínicas / Maternal risk factors associated with fetal macrosomia in Hospital de Clínicas

Introducción: La incidencia de macrosomía está entre 4,7 a 16,4%. La Organización Mundial de la Salud (OMS) en el 2012 refiere que el 6.7% de los recién nacidos en el mundo presentaron sobrepeso u obesidad. En el 2014 reportó que en las regiones de Sudamérica el 7,6% de los recién nacidos nacieron con sobrepeso. Materiales y métodos: Estudio observacional, analítico de casos y controles. El método de muestreo no probabilístico de casos consecutivos. La población accesible son pacientes que dieron a luz a recién nacidos macrosómicos en la Cátedra y Servicio de Ginecología y Obstetricia del Hospital de Clínicas. Los casos son pacientes con ecografía obstétrica del tercer trimestre que dieron a luz a recién nacido único, vivo o muerto, mayor a 37 semanas por Capurro, con peso al nacer mayor o igual a 4000 gramos en la Cátedra y Servicio de Ginecología y Obstetricia del Hospital de Clínicas - San Lorenzo, del 1 de enero a 31 de diciembre de 2017. Resultados: Con diferencia significativa (p<0,05) el estudio manifiesta oportunidad a las cesáreas con 64 (84,21%) como vía de terminación del embarazo, siendo 5,77 veces mayor en las gestaciones con feto macrosómico. Las lesiones del canal del parto se reportaron 8 (10,53%) en los partos de recién nacidos macrosómico y 46 (30,26%) en los controles, representando diferencia significativa. Conclusión: los factores de riesgo materno asociados con macrosomía fetal son: la macrosomía anterior, la obesidad materna pregestacional, la hipertensión inducida por el embarazo, un aumento de ponderal > 15 kg durante la gestación. La mayoría de las mujeres estudiadas fueron de procedencia urbana, en unión libre, amas de casas y con escolaridad secundaria, pero no resultaron ser factores de riesgos de recién nacidos macrosómicos. No se encontró asociación entre macrosomía fetal y diabetes gestacional.

Introduction: The incidence of macrosomia is between 4.7 to 16.4%. The World Health Organization (WHO) in 2012 refers that 6.7% of newborns in the world were overweight or obese.9 In 2014 it reported that in the regions of South America 7.6% of newborns were born with overweight. Materials and methods: Observational, analytical study of cases and controls. The non-probability sampling method of consecutive cases. The accessible population are patients who gave birth to macrosomic newborns in the Department and Service of Gynecology and Obstetrics of the Hospital de Clínicas. The cases are patients with obstetric ultrasound of the third trimester who gave birth to a single newborn, alive or dead, greater than 37 weeks per Capurro, with a birth weight greater than or equal to 4000 grams in the Department and Service of Gynecology and Obstetrics of the Hospital de Clínicas - San Lorenzo, from January 1 to December 31, 2017. Results: With a significant difference (p <0.05), the study shows an opportunity for cesarean sections with 64 (84.21%) as the means of termination of pregnancy, being 5.77 times higher in pregnancies with a macrosomic fetus. Injuries to the birth canal were reported in 8 (10.53%) in macrosomic newborn deliveries and 46 (30.26%) in controls, representing a significant difference. Conclusion: maternal risk factors associated with fetal macrosomia are: anterior macrosomia, pre-pregnancy maternal obesity, pregnancy-induced hypertension, and a weight gain> 15 kg during pregnancy. Most of the women studied were of urban origin, in common union, housewives and with secondary schooling, but they did not turn out to be risk factors for macrosomic newborns. No association was found between fetal macrosomia and gestational diabetes.

The value of pre-pregnancy BMI, gestational maximum fasting blood glucose and weight gain during pregnancy to evaluate fetal macrosomia after 28 weeks of gestational diabetes mellitus / 中国医师杂志

Objective:To analyze the relationship between pre-pregnancy body mass index (BMI), gestational random fasting glucose maximum, weight gain during pregnancy, and the occurrence of macrosomia in pregnant women diagnosed with gestational diabetes after 28 weeks gestation.Methods:The clinical data of 310 pregnant women with gestational diabetes after 28 weeks of diagnosis in Xuanwu Hospital of Capital Medical University in 2014 were retrospectively analyzed. They were divided into observation group (96 cases) with macrosomia and control group (214 cases) with normal birth weight according to the weight of newborn. The differences of BMI before pregnancy, the highest value of fasting blood glucose during pregnancy and weight gain during pregnancy between the two groups were analyzed.Results:The pre-pregnancy BMI , the highest value of random fasting blood glucose and weight gain during pregnancy in macrosomia group were significantly higher than those in non macrosomia group ( P<0.05); And the best cut-off point for predicting the delivery of macrosomia in pregnant women with gestational diabetes after 28 weeks of pregnancy was 22.077 kg/m 2, 4.965 mmol/L and 17.400 kg, respectively. The area under the curve (AUC) was 0.646, 0.595 and 0.699 respectively. After correction of confounding factors, the BMI ( OR=1.238, 95% CI: 1.132, 1.354, P<0.001) and weight gain during pregnancy ( OR=1.189, 95% CI: 1.120, 1.262, P<0.001) were risk factors for macrosomia in gestational diabetes mellitus after 28 weeks of gestation ( P<0.05). Conclusions:Pre-pregnancy BMI>22.077 kg/m 2, gestational maximum fasting blood glucose >4.965 mmol/L and gestational weight gain >17.400 kg were all high risk factors for gestational diabetes mellitus pregnant women after 28 weeks. For pregnant women with gestational diabetes, active prenatal intervention and health management are of great significance in reducing the risk of macrosomia.

The correlation of glycosylated hemoglobin level in the late pregnancy gestational diabetes mellitus patients and fetal weights, neonatal Apgar scores, maternal and infant adverse outcomes / 中国医师进修杂志

Objective:To analyze the correlation of glycosylated hemoglobin (HbA 1c) level in the late pregnancy gestational diabetes mellitus (GDM) patients and fetal weights, neonatal Apgar scores, maternal and infant adverse outcomes. Methods:One hundred and eighty-seven pregnant women who were diagnosed with GDM from January 2015 to July 2019 and delivered in Yixing People′s Hospital after standard diagnosis and treatment were divided into four groups (A group: HbA 1c<6.0%, 65 cases; B group: HbA 1c: 6.0% - 6.5%, 49 cases; C group: HbA 1c 6.6%-7.0%, 39 cases; D group: HbA 1c>7.0%, 34 cases) according to the HbA 1c examination results at 28 to 32 weeks of gestation. General data, fetal weights, neonatal Apgar scores and maternal and infant adverse outcomes were compared among the four groups. The correlation between GDM HbA 1c and fetal weights, neonatal Apgar scores and maternal and infant adverse outcomes were analyzed by unconditional Logistic regression. Results:In general data of GDM pregnant women with different HbA 1c levels, only oral glucose tolerance test (OGTT) fasting blood glucose: (4.68 ± 0.60), (4.89 ± 0.69), (5.23 ± 0.90), (6.48 ± 2.17) mmol/L; postprandial 1 h blood glucose: (9.84 ± 1.56), (10.09 ± 1.84), (10.6 ± 2.01), (12.74 ± 4.12) mmol/L; postprandial 2 h blood glucose: (8.65 ± 1.49), (8.86 ± 1.76), (9.28 ± 2.15), (11.56 ± 4.93) mmol/L, showed statistically significant differences ( P<0.05). Among the newborns of GDM pregnant women with different HbA 1c levels, there were statistically significant differences in the macrosomic infant rates: 1.54%(1/65), 10.20%(5/49), 12.82%(5/39), 17.65%(6/34); rates of neonatal Apgar scores<7 points:13.85%(9/65), 16.33%(8/49), 25.64%(10/39), 44.12%(15/34); the proportion of maternal and infant adverse outcomes: 24.62%(16/65), 24.49%(12/49), 28.21%(11/39), 50.00%(17/34), showed statistically significant differences ( P<0.05). After adjusting OGTT by unconditional Logistic regression analysis, HbA 1c (6.6%-7.0% and>7.0%) was independent risk factor for macrosomic infants: OR = 1.430, 95% CI = 1.035-1.977, P = 0.030; OR = 2.042, 95% CI = 1.311-3.180, P = 0.001; maternal and infant adverse outcomes: OR = 1.774, 95% CI = 1.130-2.874, P = 0.010; OR = 3.387, 95% CI = 1.608-7.133, P = 0.001. HbA 1c>7.0% was independent risk factors for neonatal Apgar scores<7 points: OR = 1.848 95% CI = 1.086-3.143, P = 0.023. Conclusions:There was a significant correlation between HbA 1c in GDM pregnant women in the late pregnancy and macrosomic infants, neonatal Apgar scores, and maternal and infant adverse outcomes. In particular, GDM pregnant women with HbA 1c>7.0% should be alert to the risk of macrosomic infants, neonatal Apgar score<7 points, and maternal and infant adverse outcomes.

Ganho de peso em mulheres durante o período da gestação: uma revisão / Weight gain in women during the pregnancy period: a review

O ganho de peso na gravidez é inevitável devido às alterações sofridas pelo corpo para poder acomodar o feto em formação. Essas mudanças decorrem, principalmente, do aumento da produção de certos hormônios, que controlam as alterações físicas. Entretanto, o ganho excessivo de massa se torna comum entre gestantes e pode trazer prejuízos tanto para elas, quanto para o feto em desenvolvimento. O bebê também pode sofrer com o aumento de peso, sendo um dos resultados mais comuns a macrossomia fetal. O objetivo deste trabalho foi analisar os fatores que levam ao ganho de peso nas mulheres durante a gravidez e o período pós-parto. O presente estudo se trata de uma revisão bibliográfica de artigos publicados entre 2013 e 2018, realizada no período de agosto a novembro de 2019. As informações foram coletadas através da base de dados Scientific Eletronic Library (SciELO) e os sujeitos em estudo eram mulheres gestantes ou puérperas habitantes das regiões Sul, Sudeste e Nordeste do Brasil. Concluiu-se que o ganho excessivo de peso traz consequências tanto para a mulher, quanto para o feto, podendo resultar em grandes prejuízos a ambos, principalmente no período após o parto. É necessário que haja acompanhamento médico durante todas as fases da gestação e a realização de uma dieta que corresponda às necessidades da gestante e do seu filho, permitindo o seu desenvolvimento sem causar danos à sua saúde

Weight gain in pregnancy is inevitable due to changes in the body to accommodate the developing fetus. These changes are mainly due to the increased production of certain hormones that control physical changes. However, excessive mass gain becomes common among pregnant women and can cause harm to both women and the developing fetus. The baby may also suffer from weight gain, one of the most common outcomes being fetal macrosomia. The aim of this study was to analyze the factors leading to weight gain in women during pregnancy and the postpartum period. This study is a bibliographic review of articles published between 2013 and 2018, carried out from August to November 2019. The information was collected through the Scientific Electronic Library (SciELO) database and the subjects were pregnant or postpartum women living in the South, Southeast and Northeast regions of Brazil. It was concluded that excessive weight gain hasconsequences for both women and the fetus, and may result in great harm to both,especially in the postpartum period. Medical follow-up is required during all stages of pregnancy and a diet that meets the needs of the pregnant woman and her child, allowing her to develop without causing harm to her health

Ganancia de peso gestacional como predictor de macrosomía y bajo peso al nacer: revisión sistemática / Gestational weight gain as a predictor of macrosomia and low birth weight: a systematic review

RESUMEN Objetivos: Evaluar la capacidad predictiva de las recomendaciones de ganancia de peso gestacional respecto del bajo peso al nacer (BPN) y la macrosomía neonatal, propuestas por el Institute of Medicine (IOM) y el Centro Latinoamericano de Perinatología (CLAP). Materiales y métodos: La búsqueda bibliográfica se realizó en PubMed, Embase (vía Ovid), Cochrane Library, EBSCO host, Scopus, LILACS y SciELO. La calidad metodológica se evaluó utilizando QUADAS 2. Resultados: Se obtuvieron 1192 artícu los, cinco cumplieron los criterios de inclusión, ningún estudio evaluó las recomendaciones CLAP. La sensibilidad y especificidad para predecir el BPN y la macrosomía variaron largamente según el país de realización del estudio. En las cohortes de América Latina, la sensibilidad para predecir el BPN varió entre 62,8% y 74%, y la especificidad, entre 61,7% y 68%, mientras que la sensi bilidad para predecir macrosomía fue 28,8%, y la especificidad, 43,8%. En la mayoría de estudios el valor predictivo positivo fue inferior al 25%, y el valor predictivo negativo, superior al 90%. La mayoría de los estudios tuvo alto riesgo de sesgo y problemas de aplicabilidad en la selección de pacientes. Conclusiones: La limitada calidad metodológica y representatividad de las cohortes estudiadas, probables factores de confusión no ajustados y modestos valores de sensibilidad y especificidad sugieren la necesidad de desarrollar estudios para establecer recomendaciones que se ajusten a las características epidemiológicas de la población peruana.

ABSTRACT Objectives: To evaluate the predictive capacity of gestational weight gain recommendations regarding low birth weight (LBW) and neonatal macrosomia, proposed by the Institute of Medicine (IOM) and the Latin American Center of Perinatology (CLAP). Mate rials and methods: The bibliographic search was performed in PubMed, Embase (via Ovid), Cochrane Library, EBSCOhost, Sco pus, LILACS and SciELO. Methodological quality was evaluated using QUADAS 2. Results: A total of 1,192 articles were identified, only 5 articles met the inclusion criteria, no study evluated the CLAP recomendations. Sensitivity and specificity to predict LBW and macrosomia varied widely depending on which country the study took place. In the Latin American cohorts, the sensitivity for predicting LBW ranged from 62.8% to 74% and the specificity from 61.7% to 68%, while the sensitivity for predicting macrosomia was 28.8% and the specificity 43.8%. In most studies the positive predictive value was less than 25%, and the negative predictive va lue was more than 90%. Most studies had high risk of bias and applicability problems in patient selection. Conclusions: The limited methodological quality and representativeness of the studied cohorts, probable unadjusted confounding factors and modest values of sensitivity and specificity suggest the need to develop studies aimed at providing recommendations that fit the epidemiological characteristics of the Peruvian population.
