Complicações gestacionais e perinatais em mulheres com síndrome dos ovários policísticos / Gestational and perinatal complications in women with Polycystic Ovary Syndrome

A síndrome dos ovários policísticos (SOP) é uma condição endócrina frequente em mulheres em idade reprodutiva. O quadro clínico é manifesto por anovulação crônica hiperandrogênica, acompanhada muitas vezes de infertilidade; além disso, essa condição está associada ao aumento de distúrbios do metabolismo glicídico e a diversos outros riscos em longo prazo. Uma vez gestante, a mulher portadora de SOP apresenta risco aumentado em 2,8 vezes para o diabetes gestacional, em 2,0 a 4,0 vezes para o desenvolvimento de síndromes hipertensivas da gestação e em 2,3 vezes para internação em UTI neonatal. Independentemente do excesso de peso, que é comumente associado à síndrome e que certamente potencializa o risco de complicações, a SOP por si só promove alterações que cursam com a elevação dessas complicações. Esta é uma revisão narrativa sobre as potenciais complicações gestacionais relacionadas à SOP e compila a literatura mais atual sobre o tema.(AU)

Impact of overweight and obesity on pregnancy outcomes in women with gestational diabetes - results from a retrospective multicenter study

ABSTRACT Objective The aim of this study was to evaluate the impact of pre-pregnancy body mass index (BMI) on pregnancy outcomes in women with gestational diabetes (GD). Subjects and methods Retrospective multicenter study using data from the Portuguese National Register. We included women with GD with a singleton pregnancy. GD diagnosis was according to the International Association of the Diabetes and Pregnancy Study Group criteria. Women were divided into groups according to their pre-pregnancy BMI: < 18.5 kg/m2 (underweight), ≥ 18.5 and < 25.0 kg/m2 (normal weight), ≥ 25 and < 30 kg/m2 (overweight) and ≥ 30 kg/m2 (obese). Results We included 3,103 pregnant women with GD, 29.6% (n = 918) were overweight and 27.3% (n = 846) were obese. Compared to normal weight, the overweight and obese groups had a higher percentage of gestational hypertension (4.0% and 8.5% vs. 2.1%), cesarean delivery (32.8% and 41.3% vs. 27.9%), macrosomia (3.9% and 6.7% vs. 2.4%), and large for gestational age (LGA) newborns (8.3% and 13.5% vs. 6.0%). Obesity increased the risk of gestational hypertension (OR 4.5, p < 0.001), preeclampsia (OR 1.9, p = 0.034), cesarean delivery (OR 2.0, p < 0.001), macrosomia (OR 3.1, p < 0.001) and LGA (OR 2.3, p < 0.001). Conclusion In pregnant women with GD, pregnancy complications increase with pre-pregnancy BMI. In obese women, appropriate diet and counseling prior to gestation and more aggressive medical intervention during pregnancy are needed in order to prevent macrosomic and LGA newborns and to reduce maternal complications.

Gestational diabetes in the population served by brazilian public health care. prevalence and risk factors / Diabetes gestacional na população atendida pelo sistema público de saúde no Brasil. prevalência e fatores de risco

Abstract Objective To assess the prevalence of gestational diabetes mellitus and the main associated risk factors in the population served by the Brazilian Unified Health System in the city of Caxias do Sul, state of Rio Grande do Sul. Materials and Methods A descriptive, cross-sectional and retrospective study was conducted. Maternal variables were collected from the medical records of all pregnant women treated at the basic health units in 2016. Hyperglycemia during pregnancy (pregestational diabetes, overt diabetes and gestational diabetes mellitus) was identified by analyzing the results of a 75-g oral glucose tolerance test, as recommended by the Brazilian Ministry of Health. Based on the data, the women were allocated into two groups: the gestational diabetes group and the no gestational diabetes group. Results The estimated prevalence of gestational diabetes among 2,313 pregnant women was of 5.4% (95% confidence interval [95%CI]: 4.56-6.45). Pregnant women with 3 or more pregnancies had twice the odds of having gestational diabetes compared with primiparous women (odds ratio [OR]=2.19; 95%CI: 1.42-3.37; p<0.001). Pregnant women aged 35 years or older had three times the odds of having gestational diabetes when compared with younger women (OR=3.01; 95%CI: 1.97-4.61; p<0.001). Overweight pregnant women were 84% more likely to develop gestational diabetes than those with a body mass index lower than 25 kg/m2 (OR =1.84; 95%CI: 1.25-2.71; p=0.002). A multivariable regression analysis showed that being overweight and being 35 years old or older were independent variables. Conclusion In this population, the prevalence of gestational diabetes mellitus was of 5.4%. Age and being overweight were predictive factors for gestational diabetes.

Resumo Objetivo Avaliar a prevalência de diabetes mellitus gestacional, e dos principais fatores de risco associados, em população usuária do Sistema Único de Saúde em Caxias do Sul-RS. Métodos Um estudo descritivo, transversal e retrospectivo foi feito. As variáveis maternas foramcoletadas de registros de prontuários de todas gestantes atendidas nas Unidades Básicas de Saúde do município em 2016. A identificação de hiperglicemia na gestação (diabetes pré-gestacional, diabetes identificado durante a gestação e diabetes mellitus gestacional) foi feita pela avaliação dos resultados do teste oral de tolerância com 75 g glicose, conforme preconizado pelo Ministério da Saúde. Com base nesses dados, as gestantes foram separadas em dois grupos: o grupo com diabetes gestacional e o grupo sem diabetes gestacional. Resultados A prevalência estimada de diabetes gestacional em 2.313 gestantes foi de 5,4% (intervalo de confiança de 95% [IC95%]: 4,56-6,45). Gestantes com 3 ou mais gestações apresentaram chance 2 vezes maior para a ocorrência de diabetes gestacional, quando comparadas às primigestas (razão de possibilidades [RP]=2,19; IC95%: 1,42- 3,37; p<0,001). Gestantes com idade de 35 anos ou mais apresentaram chance três vezes maior do que as mais jovens (RP=3,01; IC95%: 1,97-4,61; p<0,001). A chance de desenvolver diabetes gestacional em gestantes com sobrepeso foi 84% maior do que a das comíndice demassa corporal inferior a 25 kg/m2 (RP=1,84; IC95%: 1,25-2,71; p=0,002). A análise de regressão multivariada mostrou sobrepeso e idade materna como variáveis com associação independente. Conclusão Nesta população, a prevalência de diabetes mellitus gestacional foi de 5,4%. Idade materna e sobrepeso pré-gestacional foram fatores preditivos para diabetes gestacional.

Pregestational body mass index, weight gain during pregnancy and perinatal outcome: a retrospective descriptive study / Índice de massa corporal pré-gestacional, ganho de peso na gestação e resultado perinatal: estudo descritivo retrospectivo

ABSTRACT Objective To analyze the pregestational body mass index and weight gain during pregnancy, and to associate data to perinatal outcomes of pregnant women from a Prenatal Care Program. Methods A retrospective study was carried out with 151 patients seen at the Healthy Gestation Program of Hospital Israelita Albert Einstein . Data were collected from a medical chart review of the patients seen between March 2015 and March 2016. Results The chance of developing gestational diabetes for obese patients in early gestation was estimated at 7.5-fold as compared to patients with low or normal body mass index. Conclusion There was a significant association between obesity in early pregnancy and the occurrence of gestational diabetes mellitus in this population.

RESUMO Objetivo Analisar o índice de massa corporal pré-gestacional e o ganho de peso na gestação, e associar os dados a desfechos perinatais de gestantes de um Programa de Gestação Saudável. Métodos Estudo retrospectivo realizado com 151 pacientes atendidas no Programa de Gestação Saudável do Hospital Israelita Albert Einstein. Os dados foram coletados a partir da revisão de prontuário das pacientes atendidas entre março de 2015 e março de 2016. Resultados A chance de desenvolvimento de diabetes gestacional para as pacientes com obesidade no início da gestação foi estimada em 7,5 vezes a mesma chance entre as pacientes com índice de massa corporal baixo ou normal no início da gravidez. Conclusão Houve associação significativa entre obesidade no início da gravidez e a ocorrência de diabetes mellitus gestacional nesta população.

Dietary patterns of pregnant women, maternal excessive body weight and gestational diabetes / Padrões alimentares de gestantes, excesso de peso materno e diabetes gestacional

ABSTRACT OBJECTIVE To investigate the relationship between the dietary patterns of pregnant women with maternal excessive body weight and gestational diabetes mellitus. METHODS A cross-sectional study conducted with a convenience sample of 785 adult pregnant women attended by the Unified Health System of Ribeirão Preto, state of São Paulo, between 2011 and 2012. Two 24-hour dietary recalls, corrected by the multiple source method, were employed . For the classification of the body mass index and the diagnosis of gestational diabetes mellitus, the criteria by Atalah and the World Health Organization were used, respectively. Dietary patterns were obtained by principal component analysis using the Varimax rotation method. The relationship between adherence to patterns, overweight and obesity was analyzed by multinomial logistic regression models and the relationship with gestational diabetes mellitus by adjusted unconditional logistic regression models. RESULTS We identified four dietary patterns: "traditional Brazilian"; "snacks"; "coffee" and "healthy". Women with a higher adherence to the "Healthy" (OR = 0.52; 95%CI 0.33-0.83) and "Brazilian Traditional" patterns (OR = 0.61; 95%CI 0.38-0.96) presented a lower chance of obesity, when compared to women with lower adherence, regardless of confounding factors. After adjustment for maternal excessive body weight, there was no association between dietary patterns and gestational diabetes mellitus. CONCLUSIONS Among the pregnant women, greater adherence to "traditional Brazilian" and "healthy" patterns was inversely associated with obesity, but no relationship was identified with gestational diabetes mellitus after adjusting for excessive body weight. Prospective studies are recommended to investigate the relationship between dietary patterns, overweight and gestational diabetes mellitus, reducing the chance of reverse causality.

RESUMO OBJETIVO Investigar a relação entre os padrões alimentares de gestantes com o excesso de peso materno e o diabetes mellitus gestacional. MÉTODOS Estudo transversal conduzido em uma amostra de conveniência de 785 gestantes adultas atendidas pelo Sistema Único de Saúde de Ribeirão Preto, SP, entre 2011 e 2012. Dois inquéritos recordatórios de 24 horas, corrigidos pelo multiple source method, foram empregados . Para a classificação do índice de massa corporal e do diagnóstico do diabetes mellitus gestacional, utilizou-se os critérios de Atalah e da Organização Mundial da Saúde, respectivamente. Os padrões alimentares foram obtidos por análise de componentes principais, utilizando o método de rotação Varimax . A relação entre a adesão aos padrões e sobrepeso e obesidade foi analisada por modelos de regressão logística multinomial e a relação entre adesão aos padrões e diabetes mellitus gestacional, por modelos de regressão logística não condicional ajustados. RESULTADOS Identificamos quatro padrões alimentares: "tradicional brasileiro"; "lanches"; "café" e "saudável". Observou-se que mulheres com maior adesão ao padrão "saudável" (OR = 0,52; IC95% 0,33-0,83) e "tradicional brasileiro" (OR = 0,61; IC95% 0,38-0,96) apresentaram menor chance de obesidade que as mulheres com menor adesão, independentemente de fatores de confusão. Após ajuste pelo excesso de peso materno, não houve associação entre os padrões alimentares e o diabetes mellitus gestacional. CONCLUSÕES Entre as gestantes, a maior adesão aos padrões "tradicional brasileiro" e "saudável" foi inversamente associada à obesidade, mas nenhuma relação foi identificada com o diabetes mellitus gestacional após ajuste pelo excesso de peso. Estudos prospectivos são recomendados para investigar a relação entre padrões alimentares e excesso de peso e diabetes mellitus gestacional, reduzindo a chance de causalidade reversa.

Relationship between minimally and ultra-processed food intake during pregnancy with obesity and gestational diabetes mellitus / A relação entre consumo de alimentos minimamente processados e ultraprocessados durante a gestação e obesidade e diabetes mellitus gestacional / La relación entre el consumo de comida mínimamente procesada y ultraprocesada durante embarazos con obesidad y diabetes mellitus gestacional

This study aimed to investigate the relationship between food intake (considering the nature, extent, and purpose of food processing) during pregnancy and overweight, obesity, and gestational diabetes mellitus conditions. This is a cross-sectional study conducted among 785 adult women in singleton pregnancies (between 24th and 39th weeks of gestation) in Brazil. Usual food intake was estimated by the Multiple Source Method, using two 24-hour dietary recalls. The food groups of interest in this study were the unprocessed or minimally processed foods and ultra-processed foods. The World Health Organization criteria for the diagnosis of gestational diabetes mellitus and the Atalah criteria for excess weight were used. Adjusted multinomial logistic regression models were used to assess the relationship between energy contribution (%E) from foods with overweight and obesity conditions and, adjusted logistic regression models for gestational diabetes mellitus. In total, 32.1% participants were overweight, 24.6% were obese, and 17.7% of women were diagnosed with gestational diabetes mellitus . After adjustments, an inverse association between the highest tertile of %E from the intake of unprocessed or minimally processed foods and obesity was found [0.49 (0.30-0.79)]. Moreover, a positive association between the highest tertile of %E from ultra-processed food intake [3.06 (1.27-3.37)] and obesity was observed. No association between food intake (considering the nature, extent, and purpose of food processing) during pregnancy and overweight or gestational diabetes mellitus was found. The findings suggest a role of food processing in obesity but not in gestational diabetes mellitus. Further research is warranted to provide robust evidence on the relationship between the role of processed foods in obesity and gestational diabetes mellitus.

O objetivo deste estudo foi investigar a relação entre o consumo de alimentos (considerando a natureza, extensão e propósito do processamento de alimentos) durante a gestação e sobrepeso, obesidade e diabetes mellitus gestacional. Estudo transversal realizado com 785 mulheres adultas com gestações únicas (24ª-39ª semanas de gestação) no Brasil. O consumo usual de alimentos foi estimado usando o Multiple Source Method, usando recordatórios alimentares de 24 horas. Os grupos alimentares de interesse neste estudo foram os alimentos não-processados e minimamente processados e os alimentos ultraprocessados. Os critérios da Organização Mundial da Saúde para diagnóstico de diabetes mellitus gestacional e critérios de Atalah para excesso de peso foram usados. Modelos de regressão logística multinomial foram empregados para avaliar a relação entre a contribuição energética (%E) de alimentos e sobrepeso e obesidade, e modelos de regressão logística ajustados foram usados para diabetes mellitus gestacional. No total, 32,1% das gestantes estavam com sobrepeso, 24,6% com obesidade e 17,7% foram diagnosticadas com diabetes mellitus gestacional. Após ajustes, uma associação inversa entre obesidade e o maior tercil de %E do consumo de alimentos não-processados ou minimamente processados foi encontrada [0,49 (0,30-0,79)]. Além disso, uma associação positiva entre obesidade e o maior tercil de %E do consumo de alimentos ultraprocessados [3,06 (1,27-3,37)] foi observada. Nenhuma associação entre consumo de alimentos (considerando a natureza, extensão e propósito do processamento de alimentos) durante a gestação e sobrepeso ou diabetes mellitus gestacional foi encontrada. Os resultados sugerem o papel do processamento de alimentos na obesidade, mas não na diabetes mellitus gestacional. Pesquisas adicionais são necessárias para fornecer evidências robustas sobre a relação entre o papel do processamento de alimentos na obesidade e na diabetes mellitus gestacional durante a gestação.

El objetivo del presente estudio fue investigar la relación entre el consumo de comida (considerando la naturaleza, alcance, y propósito del procesamiento de comida) durante el embarazo y el sobrepeso, obesidad, y diabetes mellitus gestacional. Se realizó un estudio transversal con 785 mujeres adultas de embarazos únicos (24ª-39ª semanas de gestación) en Brasil. El consumo habitual se estimó mediante un Multiple Source Method, usando dos encuestas de 24-hour en relación con los hábitos alimentarios. Los grupos de comidas de interés en el presente estudio fueron los mínimamente procesados o sin procesar y los productos de comida ultraprocesada. Se utilizaron criterios de la Organización Mundial de la Salud para el diagnostico de diabetes mellitus gestacional, y los criterios Atalah para el sobrepeso. Se utilizaron modelos ajustados de regresión logística multinomial para evaluar la relación entre la contribución energética (%E) de comidas con el sobrepeso y la obesidad, y modelos ajustados de regresión logística para la diabetes mellitus gestacional . En total, un 32,1% sufrían sobrepeso, un 24,6% eran obesas, y un 17,7% de las mujeres fueron diagnosticadas con diabetes mellitus gestacional. Tras los ajustes, se encontró una asociación inversa entre el tercil más alto de %E, procedente del consumo de comidas sin procesar o mínimamente procesadas con la obesidad [0,49 (0,30-0,79)]. Asimismo, se encontró una asociación positiva entre el tercil más alto de %E de comida ultraprocesada [3,06 (1,27-3,37)] y la obesidad. No se encontró ninguna asociación entre el consumo de comida (considerando la naturaleza, alcance, y propósito de la comida procesada) durante el embarazo y el sobrepeso, respecto a la diabetes mellitus gestacional. Los resultados sugieren la importancia de la comida procesada en la obesidad pero no así en la diabetes mellitus gestacional. Son necesarias más investigaciones para proporcionar evidencias sólidas sobre la relación entre el papel de la comida procesada en la obesidad y diabetes mellitus gestacional durante el embarazo.

Conocimientos sobre diabetes gestacional en embarazadas de un Hospital Público del Noroeste de México. Resultados de una encuesta / Knowledge about gestational diabetes in pregnant women a Public Hospital in the Northwest of Mexico. Results of a survey

RESUMEN Introducción: La Diabetes Gestacional (DG) es la intolerancia a carbohidratos que se reconoce por primera vez durante el embarazo. En México la prevalencia es del 8.7-17.7%. Estas pacientes tienen mayor riesgo de complicaciones maternas-fetales en comparación con la población general. Objetivo: Determinar el nivel de conocimiento sobre factores de riesgo y complicaciones materno-fetales de DG. Métodos: Se realizó una encuesta en un hospital público del Noroeste de México con 150 embarazadas, se midió el conocimiento sobre factores de riesgo y complicaciones materno-fetales relacionadas con DG mediante una encuesta elaborada y validada con KR-20 del 0.87 y Pérez-Padilla y Viniegra de 8. Resultados: La edad media de la población fue 27 años, con estrato socioeconómico II de Graffar en 88%, predominando escolaridad preparatoria en 41%, el 81% de ellas cuenta con pareja, 79% residen en área urbana, 57% es trabajadora, 80% sin coomorbilidades, 90% sin antecedente de DG, así como no haber recibido platicas sobre DG en 69%. El nivel de conocimiento encontrado fue: 48% azar, 19% muy bajo, 16% bajo, 11% regular, 2% alto, 4% muy alto. Conclusiones: Existe un bajo nivel de conocimiento de factores de riesgo y complicaciones de la DG entre las embarazadas. Éste nivel aumenta a mayor nivel educativo y económico, al tener antecedente de diabetes gestacional en embarazos previos y de recibir pláticas sobre este tema.

ABSTRACT Introduction: Gestational Diabetes (GD) is the carbohydrate intolerance that is recognized for the first time during pregnancy. In Mexico, the prevalence is 8.7-17.7%. These patients have a higher risk of maternal-fetal complications compared to the general population. Objective: To determine the level of knowledge about risk factors and maternal-fetal complications of GD. Methods: A survey was conducted in a public hospital in Northwest Mexico, with 150 pregnant women, knowledge about risk factors and maternal-fetal complications related to GD was measured through a survey developed and validated with KR-20 of 0.87 and Perez-Padilla and Viniegra of 8. Results: The average age of the population was 27 years, with Graffar socioeconomic level II in 88%, with preparatory schooling prevailing in 41%, 81% of them have a partner, 79% live in an urban area, 57% are working, 80% without coomorbidity, 90% without background of DG, as well as not having received talks on DG in 69%. The level of knowledge found was: 48% chance, 19% very low, 16% low, 11% regular, 2% high, 4% very high. Conclusions: There is a low level of knowledge of risk factors and complications of GD among pregnant women. This level increases to a higher educational and economic level, having a history of gestational diabetes in previous pregnancies and receiving talks on this topic.

Diabetes Gestacional: asociación con grupo ABO / Association of abo blood groups with gestational diabetes mellitus

Background: ABO and Rhesus blood systems are associated with type 2 Diabetes Mellitus (DM2). Gestational Diabetes (GDM) is a model to study DM. Aim: To study the association between GDM and ABO and Rhesus groups. Material and Methods: A retrospective cohort study was performed in 1,078 women who gave birth to a singleton in Talca Regional Hospital, Chile, during 2008. We analyzed personal, obstetric, medical data and ABO and Rh blood groups. Results: GDM was diagnosed in 6.6% of women. Age and body mass index were significantly associated with GDM. There were no differences in Rh blood groups (p = 0.604), while ABO groups were different between GDM and controls. B antigen was present in 3% of GDM women and in 10.8% of controls (p = 0.037), with an odds ratio of 0.25 after adjusting for other associated risk factors (p = 0.06). Conclusions: ABO group is suggested as a possible protector marker for GDM.

La multiparidad como factor de riesgo de diabetes mellitus gestacional / Multiparity as a Risk Factor for Gestational Diabetes Mellitus

Introducción: se estima que en Perú la prevalencia de Diabetes Mellitus es de 7 por ciento y uno de cada 100 de estos casos es de tipo gestacional. Un reporte previo menciona que la Diabetes Mellitus Gestacional afecta al 4 por ciento de las gestantes peruanas. Objetivo: determinar los factores de riesgo potenciales para desarrollar diabetes mellitus gestacional. Métodos: estudio de casos y controles realizado en el Hospital Alberto Sabogal mediante recolección de historias clínicas desde 2009 hasta 2014. Se define como caso las gestantes con diagnóstico de diabetes mellitus gestacional mediante una prueba de tolerancia oral a la glucosa, previa glucosa en ayunas anormal y control a la gestante sin valores indicativos de diabetes mellitus gestacional. Las variables de interés fueron paridad, antecedente de cesáreas, abortos y recién nacido con mayor peso. Los modelos de regresión logística fueron calculados para estimar odd ratios e intervalos de confianza al 95 por ciento. Resultados: se incluyeron 84 casos y 336 controles. En el modelo multivariado, la multiparidad incrementó el riesgo de diabetes mellitus gestacional (OR= 3,54; IC 95 por ciento 1,55 - 8,14). También hubo antecedente de abortos, a partir del segundo (OR= 3,40, IC 95 por ciento 1,55-7,44) y cesáreas previas (una cesárea OR= 3,5 IC 95 por ciento 1,89-6,47 y más de dos cesáreas OR= 8,35 IC 95 por ciento 3,50-19,95). La multiparidad, dos o más abortos y mayor número de cesáreas son factores de riesgo para diabetes mellitus gestacional. Conclusiones: el presente estudio describe la asociación de la diabetes mellitus gestacional con algunos antecedentes obstétricos como la multiparidad, el antecedente de cesáreas y/o abortos. Por esta razón, se recomienda implementar medidas de prevención e identificación de gestantes con signos de alarma de diabetes mellitus gestacional para realizar un diagnóstico temprano, así como el seguimiento de estas pacientes en el posparto(AU)

Introduction: the prevalence of diabetes mellitus is estimated to be 7 percent in Peru. One in 100 of these cases is gestational type. A previous report said gestetional diabetes mellitus affects 4 percent of Peruvian pregnant. Objectives: identify risk factors for gestational diabetes mellitus (GDM). Methods: acase-control study was performed in Alberto Sabogal Hospital, collecting medical records from 2009 to 2014. 84 cases and 336 controls were included. A case was defined as a pregnant women diagnosed with GDM by an oral glucose tolerance test (OGTT) after an abnormal fasting glucose and control was defined as a pregnant women without GDM indicative values. The study outcome was GDM. The variables of interest were multiparity, previous cesarean section, abortions, newborn with the greatest weight. Logistic regression were used to calculate the odds ratio (OR) and a confidence interval of 95 percent (IC95 percent). Conclusions: this study describes the association of gestational diabetes mellitus with some obstetrical history as multiparity, history of caesarean sections and / or abortions. For this reason, it is recommended to implement prevention and identification of pregnant women with warning signs of gestational diabetes mellitus for early diagnosis and monitoring of these patients in the postpartum period(AU)

Algunas variables epidemiológicas en pacientes con diabetes mellitus gestacional / Some epidemiological variables in gestational diabetes mellitus patients

Introducción: la diabetes mellitus (DM) es considerada la enfermedad metabólica que con más frecuencia complica el embarazo.Objetivo: describir algunas variables epidemiológicas en pacientes con diabetes mellitus gestacional.Métodos: se realizó un estudio descriptivo, retrospectivo y transversal de las pacientes diagnosticadas con esta enfermedad en el período comprendido entre enero y diciembre de 2012. El universo de estudio quedó constituido por 37 pacientes. Se analizaron las siguientes variables: edad de la gestante, edad gestacional, valoración del estado nutricional a la captación del embarazo según el índice de masa corporal (IMC), antecedentes patológicos familiares y obstétricos y la necesidad de tratamiento insulínico. Los datos se obtuvieron de las historias clínicas individuales y fueron procesados mediante el paquete estadístico SPSS-11.5 de Windows ofreciendo los resultados en porcentajes y promedios como medidas de resumen.Resultados: fue mayoritario el grupo de edades entre 26-30 años con 13 (35,1), así como la edad gestacional entre las 28 y 36 semanas con 18 (48,7), el grupo de las obesas fue el que predominó, 24 (64,9). Dentro de los antecedentes obstétricos, el aborto provocado resultó ser el más encontrado 10 (27,0).Conclusiones: la mayor cantidad de pacientes con diabetes gestacional tenían entre 21 y 30 años. El diagnóstico se realizó con mayor frecuencia entre 21 y 36 semanas de gestación. Fueron mayoría las que tenían antecedentes de abortos, de mortalidad fetal o neonatal, de partos pretérmino y anomalías congénitas previas, que se consideran factores de riesgo para la diabetes gestacional.

Introduction: diabetes mellitus (DM) is considered a metabolic disease that most often complicates pregnancy.Objective: to describe some epidemiological variables in patients suffering from gestational diabetes mellitus.Methods: a descriptive, retrospective and cross-sectional study was conducted in pregnant patients diagnosed with this disease from January to December 2012. The study group was composed of 37 patients. The following variables were analyzed: age, gestational age, assessment of nutritional status at detection of pregnancy, according to body mass index (BMI), family and obstetric medical history and the need for insulin therapy. The data were obtained from individual medical records and they were processed using SPSS-11.5 for Windows offering results in percentages and averages as summary measures.Results: the majority of patients were in the age group between 26 to 30 years with 13 patients (35.1); gestational age between 28 and 36 weeks with 18 patients (48.7). 24 patients were in the obese group (64.9). Induced abortion was the most frequent finding within their obstetric history, 10 cases (27.0).Conclusions: most patients suffering from gestational diabetes were between 21 and 30 years old. The diagnosis was made more often between 21 and 36 weeks of gestation. Most of them had history of abortions, fetal or neonatal mortality, preterm delivery and pre congenital anomalies, which are considered risk factors for gestational diabetes.

Síndrome de ovario poliquístico y embarazo / Polycystic ovary syndrome and pregnancy

Background: Polycystic ovary syndrome (PCOS) is a common endocrine metabolic dysfunction closely associated with insulin resistance and obesity, which predisposes to pregnancy complications and prenatal programming of the offspring. The aim of this review is to report our experience in PCOS patients who became pregnant and were followed during the whole pregnancy. Firstly, we analyzed the effect of pregnancy on PCOS pathophysiology and secondly the role of PCOS in pregnancy outcomes. Regarding the firstpoint, during normal pregnancy a progressive insulin resistance, serum lipid changes and an increase in androgen levels is observed, which is exacerbated in the PCOS condition. This adverse intrauterine environment could have a prenatal programming effect with detrimental consequences for female or male fetuses. Regarding the second point, PCOS is associated with an increased risk for maternal complications such as gestational diabetes (GDM) and pregnancy-induced hypertension. Moreover, these adverse pregnancy outcomes are more frequently associated with an increase in low birth weight and high birth weight newborns. According to our clinical experience, PCOS patients who became pregnant and were not treated with metformin during the whole pregnancy, showed a higher prevalence of gestational diabetes and SGA newborns, which was improved with metformin treatment. In summary, pregnancy may constitute a period in which an abnormal condition is established or aggravated in the fetus of a PCOS mother. Moreover, PCOS enhanced adverse obstetric and neonatal outcomes.

Marcadores para o diagnóstico e tratamento de 924 gestações com diabetes melito gestacional / Markers of diagnosis and treament in 924 pregnancies with gestational diabetes mellitus

OBJETIVOS: Avaliar o perfil epidemiológico e a evolução de mulheres com diabetes melito gestacional (DMG), determinando fatores de risco para maior vigilância. SUJEITOS E MÉTODOS: Foram estudadas 924 gestações de 916 pacientes, de 6 de novembro de 2001 a 21 de setembro de 2009. RESULTADOS: Foram encontrados fatores de risco para DMG em 95,1 por cento dos casos. A prevalência de diabetes materno, paterno e em outros familiares foi de 24,3 por cento, 9,4 por cento e 24,7 por cento, respectivamente. Os fatores preditivos para uso de insulina foram: glicemia de jejum (GJ) no rastreamento ≥ 85, GJ no Teste Oral de Tolerância à Glicose (TOTG) ≥ 95, glicemia 2h após 75 g de glicose ≥ 200 mg/dL, DMG prévio, obesidade, HbA1c > 6 por cento e história familiar de DM em parente de primeiro grau associada à obesidade ou DMG prévio, esta última a associação mais relevante (p < 0,05). CONCLUSÕES: Os fatores de risco analisados se mostraram altamente sensíveis para a detecção de DMG, e a disposição da história familiar reforça sua relação com o DM2. Recomenda-se maior vigilância a gestantes com fatores preditivos para necessidade de insulina.

OBJECTIVES: To evaluate the epidemiological profile and outcomes of women with gestational diabetes mellitus (GDM), determining risk factors for increased vigilance. SUBJECTS AND METHODS: We studied 924 pregnancies in 916 patients between November 6, 2001 and September 21, 2009. RESULTS: Risk factors were found in 95.1 percent of cases. The prevalence of maternal diabetes, paternal diabetes and diabetes in other family members was 24.3 percent, 9.4 percent and 24.7 percent, respectively. Predictive factors for insulin use were: screening fasting glucose (FG) ≥ 85, Oral Glucose Tolerance Test (OGTT) FG ≥ 95, 2h glucose after 75 g ≥ 200 mg/dL, previous GDM, obesity, HbA1c > 6 percent, and the association of risk factors including family history of diabetes mellitus and obesity or previous GDM, the last one the most relevant (p < 0,05). CONCLUSIONS: Risk factors were very sensitive for GDM detection, and provision of family history strengthens its relationship with T2DM. Greater vigilance is recommended for patients with predictive factors for insulin requirement.

Uso dos antirretrovirais na gestação e seus possíveis efeitos adversos / Use of antiretroviral agents during pregnancy and their possible adverse effects

A transmissão vertical do HIV tem sido a forma de transmissão que mais sofreu redução nos últimos anos. O principal fator determinante para tal diminuição foi o uso da terapia antirretroviral de alta potência (HAART) nas gestantes infectadas. Atualmente, a taxa de transmissão vertical do HIV em países desenvolvidos está em torno de 2%. Apesar de seu efeito benéfico indiscutível, alguns estudos mostram possíveis efeitos colaterais causados pelo uso dos antirretrovirais nas gestantes e nos recém-nascidos. Entre os efeitos adversos mais frequentes, estão aqueles que podem estar presentes em qualquer paciente que use a medicação, como hipersensibilidade, toxicidade mitocondrial e lipodistrofia. No entanto, existem também os efeitos colaterais específicos do uso destas medicações durante a gestação. Vários estudos têm sido realizados para determinar a segurança dos antirretrovirais no binômio mãe e feto. Os possíveis efeitos adversos descritos pelo uso dos antirretrovirais na gestação são: resistência à insulina e o desenvolvimento de diabetes gestacional; pré-eclâmpsia; aumento de incidência de malformações congênitas; maior índice de parto pré-termo e/ou de baixo peso ao nascer. Esta revisão discute os possíveis efeitos adversos e suas consequências

HIV vertical transmission has been the route of transmission that most declined in the last years. The main factor implied in this mother-to-child-transmission reduction was the routine use of highly active antiretroviral therapy (HAART) by infected pregnant women. Currently, the HIV vertical transmission rate in developed countries is about 2%. Although there is an incontestable benefic effect of antiretroviral therapy, some studies show possible adverse effects in pregnant women and newborns after using the antiretroviral therapy. There are collateral effects that can occur in any patient using these drugs, such as hypersensitivity, mitochondrial toxicity, and lipodystrophy. However, there are other collateral effects, which are specific to the use of these drugs during pregnancy. Several authors have studied antiretroviral treatment in pregnancy to determine the safety of HAART to the mother-child binomial. The possible adverse effects caused by antiretroviral therapy use during pregnancy are: insulin resistance and the development of gestational diabetes; preeclampsia; higher incidence of congenital abnormalities; higher rates of preterm birth, and/or low-birth weight. This review discusses the possible adverse effects and their consequences

Obesidad pregestacional y riesgo de intolerancia a la glucosa en el embarazo y diabetes gestacional / Pregestational obesity and risk of glucose intolerance in pregnancy and gestational diabetes

ANTECEDENTES: La obesidad en mujeres en edad reproductiva es cada vez más frecuente y complica el embarazo aumentando el riesgo de enfermedades como la diabetes mellitus gestacional (DMG). OBJETIVO: Determinar el riesgo de presentar DMG e intolerancia a la glucosa (ITG) de acuerdo con el índice de masa corporal pregestacional (IMCPG). MÉTODO: Muestra de 489 pacientes, se clasificaron por IMCPG y se les realizó una curva de tolerancia oral a la glucosa (CTOG) de 100 g de 120 minutos. Se definió DMG con dos valores alterados en la CTOG e ITG con un solo valor alterado. Se aplicó prueba de chi cuadrada para determinar diferencia entre grupos y se obtuvo un Odds Ratio (OR), con intervalo de confianza del 95%. RESULTADOS: 9 pacientes con bajo peso, 194 con peso normal, 158 con sobrepeso y 128 con obesidad, edad gestacional promedio 31,3 ± 5,6 semanas. El 13% de las pacientes presentaron DMG, el 10,6% ITG. Las mujeres con sobrepeso presentaron un OR de 3,81 para desarrollar ITG (IC95% 1,62-8,95) y un OR de 3,7 para DMG (IC95% 1,65-8,38), mientas que las pacientes con obesidad pregestacional presentaron un OR de 6,6 para desarrollar ITG (IC95% 2,83-15,66) y un OR de 8,8 para DMG (IC95% 4,05-19,51), comparadas con mujeres con peso pregestacional normal. CONCLUSIÓN: La población mexicana tiene mayor riesgo de DMG que otras poblaciones y mayor prevalencia de sobrepeso y obesidad, por lo que se debe realizar un diagnóstico y tratamiento oportuno de DMG, previniendo complicaciones y diabetes mellitus tipo 2.

BACKGROUND: Obesity in women in reproductive age is becoming more frequent and it self complicates preg-nancy increasing the risk of diseases such as gestational diabetes mellitus (GDM). AIMS: To determine the risk of gestational diabetes mellitus (GDM) and impaired glucose tolerance (IGT) according to the pregestational body mass index (PGBMI). METHODS: Sample of 489 patients, they were classified by PGBMI and underwent an oral glucose tolerance test (OGTT) with 100 g of glucose during 120 minutes. GDM was defined with two altered valúes in the OGTT and IGT with a single altered value. A chi-square test was applied to determine difference between groups, and we obtained an Odds Ratio (OR), with a confidence level of 95%. RESULTS: 9 patients were low weight, 194 normal weight, 158 overweight and 128 obese, average gestational age 31.3 ± 5.6 weeks. 13% of the patients had GDM, 10.6% had IGT. Overweight women had an OR of 3.81 of developing IGT (95% Cl 1.62-8.95) and an OR of 3.7 of developing GDM (95% Cl 1.65-8.38), while women with prepregnancy obesity showed an OR of 6.6 of developing ITG (95% Cl 2.83-15.66) and an OR of 8.8 of developing GDM (95% Cl 4.05-19.51), all compared to women with prepregnancy normal weight. CONCLUSIONS: Mexican population has a higher risk of GDM than other populations and also a higher prevalence of overweight and obesity, so that every pregnant woman should be screening for GDM, has a diagnosis and receive treatment, preventing complications and Type 2 Diabetes.

Antropometría como predictor de diabetes gestacional: Estudio de cohorte / Anthropometry as predictor of gestational diabetes mellitus

Background: Gestational diabetes mellitus (GDM) is a high incidence disease. Easily measured predictor factors could help to implement preventive policies and early detection tests. Aim: To measure recognizable risk factors for GDM such as skinfolds and analyze the association between these factors and the development of GDM in a cohort of pregnant women. Material and Methods: Evaluation of 76 mothers that developed gestational diabetes, aged 32.2 ± 0.6 years and 324 control mothers that did not develop the disease, aged 30.1 ± 0.3 years. Weight, height, arm circumference, tricipital, bicipital, subscapular, suprailiac, knee, costal and mid-thigh skinfolds were measured in the pre-diseased stage. History of diabetes, fasting glucose and insulin levels were also evaluated. Results: Age, body mass index (BMI), fasting blood glucose, the homeostasis model assessment of insulin resistance (HOMA), bi-cipital, tricipital, costal, subscapular, suprailiac, and knee skinfolds were associated with GDM development. Age, fasting blood glucose and subscapular skinfolds were independent predictors in the logistic regression model. The odds ratio for a subs-capular skinfold over percentile 90 was 1.7 (95 percent confdence intervals: 1.07-3.04). Conclusions: Age and fasting blood glucose are independent risk factors for GDM. Subscapular skinfold is also an independent risk factor and could be used to detect high risk pregnant women and implement preventive policies.

[Relationship between cigarette smoking and gestational diabetes mellitus]

Diabetes Mellitus is a metabolic disease and the most prevalent disorder in pregnancy. Gestational diabetes mellitus is a kind of diabetes that is recognized in pregnancy. Many risk factors have been recognized for gestational diabetes mellitus. Determining new risk factors help to identify women who are at risk for diabetes. This research was conducted in order to determine the relationship between cigarette smoking before or during pregnancy and gestational diabetes mellitus in women referring to health care centers in Tehran during 2008-2009. This case control study was conducted on 110 pregnant women with gestational diabetes [case group] and 96 pregnant women without the condition [control group] referring to healthcare clinics affiliated to Research Centers of Endocrinology and Metabolism at Ayatollah Taleghani Hospitals as well as Iran Research Institute of Endocrinology and Metabolism. A questionnaire was used for collecting data by interviewing the subjects. Both groups were matched for age and parity. Demographic characteristics were similar in both groups. There was a significant difference between the two groups in cigarette smoking before or during pregnancy and occurring diabetes mellitus [p=0.0001] with an estimated odds ratio [OR] of 3.79 [%95 CI=1.37 +/- 10.53]. The present findings showed a significant relationship between cigarette smoking and gestational diabetes mellitus

Fatores de risco para diabetes mellitus gestacional na coorte de nascimentos de Pelotas, Rio Grande do Sul, Brasil, 2004 / Risk factors for gestational diabetes mellitus in the birth cohort in Pelotas, Rio Grande do Sul State, Brazil, 2004

Consensus statements by various countries have reported age, obesity, and family history of diabetes mellitus as risk factors for gestational diabetesmellitus. Other factors remain controversial. The aim of this study was to investigate factors associated with gestational diabetes among mothersof newborns from the birth cohort in Pelotas, Rio Grande do Sul State, Brazil, in 2004. We interviewed 4,243 postpartum women in hospital, with a 0.5% refusal rate. Diagnosis of gestational diabetes was self-reported. Prevalence of gestational diabetes was 2.95% (95%CI: 2.53-3.64). Crude analysis using the chi-square test showed a direct association with age, schooling, socioeconomic status, and body mass index (BMI) and an inverse association with maternal height. Non-white color, family history of diabetes mellitus, smoking in the first and second trimesters, and physical activity before the pregnancy and in the first trimester were associated with the outcome. Adjusted hierarchical analysis using logistic regression showed an association with age, non-white color, higher schooling, family history of diabetes, and BMI. Height showed borderline significance. Smoking in the first and second trimesters showed a protective effect.

Consensos de diversos países referem idade, obesidade e história familiar de diabetes mellitus como fatores de risco para diabetes mellitus gestacional. Outros fatores permanecem controversos. O objetivo deste estudo foiinvestigar fatores associados ao diabetes mellitus gestacional entre mães dos recém-nascidos da coorte de nascimentos de Pelotas, Rio Grande do Sul, Brasil, em 2004. Foram entrevistadas 4.243 puérperas no hospital, havendo 0,5% de recusas. O diagnóstico de diabetes mellitus gestacional foi auto-referido. A prevalência de diabetes mellitus gestacional foi 2,95% (IC95%: 2,53-3,64). Análise bruta realizada por meio de testes quiquadrado mostrou associação direta com aumento da idade, escolaridade, nível econômico e índice de massa corporal (IMC) e inversa com altura materna. Cor nãobranca, história familiar de diabetes mellitus, tabagismo no primeiro e segundo trimestres e atividade físicaantes da gestação e no primeiro trimestre mostraramse associados. A análise ajustada hierarquizada realizadaatravés de regressão logística mostrou associação com maior idade, cor não branca, maior escolaridade, história familiar de diabetes mellitus e maior IMC. A altura ficou no limiar da significância. Tabagismo no primeiro e segundo trimestres foi protetor.

Non classical risk factors for gestational diabetes mellitus: a systematic review of the literature / Fatores de risco não clássicos para diabetes mellitus gestacional: uma revisão sistemática da literatura

Age, obesity and family history of diabetes are well known risk factors for gestational diabetes mellitus. Others are more controversial. The objective of this review is to find evidence in the literature that justifies the inclusion of these other conditions among risk factors. The MEDLINE, Cochrane, LILACS and Pan American Health Organization databases were searched, covering articles dating from between 1992 and 2006. Keywords were used in combination (AND) with gestational diabetes mellitus separately and with each one of the risk factors studied. The methodological quality of the studies included was assessed, resulting in the selection of 41 papers. Most studies investigating maternal history of low birth weight, low stature, and low level of physical activity have found positive associations with gestational diabetes mellitus. Low socioeconomic levels, smoking during pregnancy, high parity, belonging to minority groups, and excessive weight gain during pregnancy presented conflicting results. Publication bias cannot be ruled out. Standardization of techniques, cutoff points for screening and diagnosis, as well as studies involving larger sample sizes would allow future meta-analyses.

Idade, obesidade e história familiar de diabetes são fatores de risco bem conhecidos para diabetes mellitus gestacional. Outros são controversos. O objetivo desta revisão é encontrar evidências na literatura que justifiquem a inclusão dessas condições entre os fatores de risco. Bases de dados MEDLINE, Cochrane, LILACS e Organização Pan-Americana da Saúde foram procuradas. A revisão incluiu artigos de 1992 a 2006. Palavras-chave foram usadas em combinação com diabetes mellitus gestacional separadamente e com cada um dos fatores de risco estudados. A qualidade metodológica dos estudos incluídos foi medida, totalizando 41 estudos. A maioria dos trabalhos que investigaram história materna de baixo peso, baixa estatura e baixa atividade física encontrou associação positiva com diabetes mellitus gestacional. Baixo nível sócio-econômico, fumo durante a gestação, alta paridade, pertencer a minorias e excessivo ganho de peso apresentam resultados conflitantes. Padronização de técnicas, pontos de corte para rastreamento e diagnóstico, assim como estudos envolvendo maiores amostras podem permitir futuras metanálises.
