Condição bucal de mulheres com diabetes mellitus gestacional internadas em um hospital escola no sul do Brasil / Oral condition of women with gestational diabetes mellitus admitted in a school hospital in southern Brazil

Objetivo: avaliar a condição bucal de mulheres com diabetes mellitus gestacional (DMG) internadas no Hospital Escola (HE) da Universidade Federal de Pelotas (UFPel). Métodos: trata-se de um estudo transversal retrospectivo de base hospitalar, em que dois residentes treinados realizaram a coleta dos dados por meio da avaliação dos prontuários médicos e odontológicos, no período de setembro de 2019 a março de 2020. Os dados socioeconômicos e demográficos e o diagnóstico de DMG foram coletados dos prontuários médicos, enquanto hábitos e condição bucal, dos prontuários odontológicos. A análise dos dados foi realizada no programa Stata 11.0, usando os testes Exato de Fisher e Regressão de Poisson. Resultados: foram avaliados os prontuários de 83 gestantes, destas, 37 (44,6%) apresentavam DMG. A presença de DMG esteve asso-ciada com as gestantes de maior faixa etária (62,2%) e no terceiro trimestre de gestação. Em sua maioria, tinham renda de até dois salários mínimos, eram solteiras, tinham filhos e realizaram pré-natal. Em relação à avaliação bucal, apenas a presença de cálculo dental e inflamação gengival foi estatisticamente associada à presença de DMG (p= 0,030 e 0,014 respectivamente). A autopercepção do sorriso foi considerada ruim por 40,5%, e a maioria teve dentes perdidos por cárie (64,9%). Conclusões: a prevalência de DMG foi alta entre as gestantes internadas, sendo maior em mulheres de mais idade. Presença de cálculo dental e inflamação gengival foram fortemente associadas à presença de DMG, enquanto hábitos bucais e presença de cárie não apresentaram associação. Novas pesquisas, com exames periodontais completos, são necessárias para verifi-car as condições periodontais dessas mulheres.(AU)

Aim: to assess the oral condition of women with Gestacional Diabetes Mellitus (GDM) admitted in a School Hospital (HE)/UFPel. Methods: medical and dental records, from September 2019 to March 2020, were evaluated in this hospital-based retrospective cross-sectional study. Socioeconomic and demographic data were collected from medical records, while oral condition and habits were obtained from the dental records. Statistical analysis was performed with Stata 11.0 software using Fisher's exact test and Poisson regression. Results: the medical records of 83 pregnant women were evaluated, of which 37 (44.6%) had GDM. The presence of GDM was associated with pregnant women of older age (62.2%) and most in the third trimester of pregnancy. Most of them had an income of up to two minimum wages, were single, had children and underwent prenatal care. Regarding the oral evaluation, only the presence of dental calculus and gingival inflammation was statistically associated with the presence of GDM (p = 0.030 and 0.014 respectively). The self-perception of the smile was considered bad to 40.5% and many of them had lost teeth due to caries (64.9%). Conclusions: the prevalence of GDM was high in hospitalized pregnant women, being higher in older women. Presence of dental calculus and gingival inflammation were strongly associated with the presence of GDM, while oral habits and the presence of caries were not associated. Further research, with complete periodontal examinations is necessary to verify the periodontal conditions of these women.(AU)

Gestational diabetes mellitus and obesity are related to persistent hyperglycemia in the postpartum period / Diabetes mellitus gestacional e obesidade estão relacionados à hiperglicemia persistente no período pós-parto

Abstract Objective To evaluate the obstetric and sociodemographic characteristics of gestational diabetic women who maintained hyperglycemia in the postpartum period (6-12 weeks postpartum). Methods This is a longitudinal cohort study with women who have had gestational diabetes and/or macrosomic children between March 1st, 2016 and March 1st, 2017. Between 6 and 12 weeks after birth, women who had gestational diabetes collected fasting glycemia, glucose tolerance test, and glycated hemoglobin results. The data were collected from medical records and during an interview in the first postpartum consultation. A statistical analysis was performed using frequency, percentage, Chi- Squared test, Fisher exact test, Mann-Whitney test, and multivariate Poisson regression. The significance level adopted for the statistical tests was 5%. Results One hundred and twenty-two women were included. Most of the women were younger than 35 years old (70.5%), white, multiparous, and with no history of gestational diabetes. Thirteen percent of the participants developed persistent hyperglycemia. A univariate analysis showed that maternal age above 35 years, being overweight, having grade 1 obesity and weight gain under 5 kg was related to the persistence of hyperglycemia in the postpartum period. Conclusion Maternal age above 35 years, obesity and overweight, and the diagnosis of gestational diabetes in the first trimester of pregnancy are associated with hyperglycemia during the postpartum period.

A análisemultivariada incluiu o diagnóstico no primeiro trimestre como fator de risco para hiperglicemia persistente. Conclusão Mulheres acima de 35 anos, obesidade, sobrepeso e diagnóstico de diabetes gestacional no primeiro trimestre estão relacionados com hiperglicemia persistente no período pós-parto.

Enfermedades cardio-metabólicas en el embarazo: revisión sobre diagnóstico, tratamiento y proyección del riesgo cardiovascular a largo plazo / Cardio-metabolic diseases in pregnancy: a review on diagnosis, treatment and projection of long-term cardiovascular risk

Las enfermedades cardiovasculares representan la mayor causa de morbimortalidad a nivel mundial. Si bien presenta un descenso en la población general, en las mujeres tiende a mantenerse estable la prevalencia de enfermedad coronaria. Varios factores propios de la mujer predisponen a que esto ocurra, incluyendo el embarazo, mediado tanto por los cambios hematológicos y cardiovasculares característicos de la gestación; como por patologías asociadas, principalmente trastornos hipertensivos del embarazo y diabetes gestacional. Su presencia se ha asociado fuertemente a la aparición a futuro de otras patologías de alto riesgo cardiovascular como hipertensión crónica, dislipidemia y diabetes mellitus. Dado el impacto que esto representa, se hace imperante la identificación de grupos de alto riesgo y la implementación de medidas preventivas, así como de diagnóstico precoz y tratamientos adecuados con el fin de disminuir complicaciones materno-fetales en las etapas perinatal y posparto.

Cardiovascular disease is the leading cause of morbidity and mortality worldwide. Although there is a decrease in general population, the prevalence of coronary heart disease remains stable in women. Several factors typical of womenkind predispose to cardiovascular disease, including pregnancy, mediated by hematological and cardiovascular changes characteristic of it; and by associated pathologies, mainly hypertensive disorders and diabetes. The presence of these diseases has been strongly associated with future presence of other conditions of high cardiovascular risk such as chronic hypertension, dyslipidemia and diabetes mellitus. Given this impact, the identification of high-risk groups and the implementation of preventive measures, as well as early diagnosis and adequate treatment in order to reduce both maternal and fetal complications in perinatal and postpartum stages becomes imperative.

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.

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.

Influence of maternal weight gain on birth weight: a gestational diabetes cohort

ABSTRACT Objective Our objective was to evaluate gestational weight gain (GWG) patterns and their relation to birth weight. Subjects and methods We prospectively enrolled 474 women with gestational diabetes mellitus (GDM) at a university hospital (Porto Alegre, Brazil, November 2009-May 2015). GWG was categorized according to the 2009 Institute of Medicine guidelines; birth weight was classified as large (LGA) or small (SGA) for gestational age. Adjusted relative risks (aRRs) and 95% confidence intervals (95% CIs) were determined. Results Adequate GWG occurred in 121 women [25.5%, 95% CI: 22, 30%]; excessive, in 180 [38.0%, 95% CI: 34, 43%]; and insufficient, in 173 [36.5%, 95% CI: 32, 41%]. In women with normal body mass index (BMI), the prevalence of SGA was higher in those with insufficient compared to adequate GWG (30% vs. 0%, p < 0.001). In women with BMI ≥ 25 kg/m2, excessive GWG increased the prevalence of LGA [aRR 2.58, 95% CI: 1.06, 6.29] and protected from SGA [aRR 0.25, 95% CI: 0.10, 0.64]. Insufficient vs. adequate GWG did not influence the prevalence of SGA [aRR 0.61, 95% CI: 0.31, 1.22]; insufficient vs. excessive GWG protected from LGA [aRR 0.46, 95% CI: 0.23, 0.91]. Conclusions One quarter of this cohort achieved adequate GWG, indicating that specific ranges have to be tailored for GDM. To prevent inadequate birth weight, excessive GWG in women with higher BMI and less than recommended GWG in normal BMI women should be avoided; less than recommended GWG may be suitable for overweight and obese women.

Predictors of cesarean delivery in pregnant women with gestational diabetes mellitus / Preditores de cesariana em gestantes com diabetes mellitus gestacional

Abstract Purpose The aim of this study was to evaluate which risk factors may lead patients with gestational diabetes mellitus to cesarean delivery. Methods This was a retrospective, descriptive study. The subjects of the study were pregnant women with gestational diabetes mellitus attending a public maternity hospital in the south of Brazil. The primary outcomes assessed were based on maternal and fetal characteristics. The data were correlated using an odds ratio (OR) with a 95% confidence interval (95%CI), calculated using multinomial logistic regression. Results A total of 392 patients with gestational diabetes mellitus were analyzed, and 57.4% of them had cesarean deliveries. Among the maternal characteristics, the mean age of the patients and the pregestational body mass index were greater when a cesarean delivery was performed (p = 0.029 and p < 0.01 respectively). Gestational age at birth, newborn weight, weight class according to gestational age, and Apgar score were not significant. The analysis of the OR showed that the chance of cesarean delivery was 2.25 times (95%CI = 1.49-2.39) greater if the pregnant woman was obese, 4.6 times (95%CI = 3.017-7.150) greater if she was a primigravida, and 5.2 times (95% CI = 2.702-10.003) greater if she had a previous cesarean delivery. The other parameters analyzed showed no differences. Conclusion The factors that led to an increase in the occurrence of cesarean deliveries included history of a prior cesarean section, first pregnancy, and obesity.

Resumo Objetivo O objetivo deste trabalho é avaliar quais os fatores de risco que podem levar pacientes com diabetes mellitus gestacional ao parto cesáreo. Métodos Trata-se de um estudo retrospectivo descritivo. Foram sujeitos do estudo gestantes portadoras de diabetes mellitus gestacional atendidas em uma maternidade pública do Sul do Brasil. Os desfechos primários avaliados foram baseados em características maternas e fetais. Os dados foram relacionados por meio da razão de chance (RC) com intervalo de confiança de 95% (IC95%), calculado por meio da regressão logística multinominal. Resultados Foram analisadas 392 pacientes com diabetes mellitus gestacional, das quais 57,4% tiveram o parto realizado por via cesariana. Dentre as características maternas, a idade média das pacientes e o índice de massa corporal pré-gestacional forammaiores nas ocasiões emque o parto cesáreo foi realizado (p = 0,029 e p < 0,01, respectivamente). Idade gestacional do parto, peso do recém-nascido, classe de peso de acordo com a idade gestacional e o Apgar não foram significativos. Analisando a RC, o fato de a gestante: ser obesa resultou em chance de parto cesáreo 2,25 (IC95% = 1,49- 2,39) vezes maior; ser primigesta resultou em chance de parto cesáreo 4,6 (IC95% = 3,017-7,150) vezes maior; e apresentar história de cesárea prévia resultou em 5,2 (IC95% = 2,702-10,003) vezes mais chance de ter uma nova cesárea. Os outros parâmetros analisados não apresentaram diferença. Conclusão Entre os fatores que acarretam aumento da ocorrência de nascimento por via cesariana, encontram-se: história de cesárea anterior, primeira gravidez e obesidade.

Periodontal disease and diabetes mellitus

Periodontal disease (PD) is one of the most commonly known human chronic disorders. The relationship between PD and several systemic diseases such as diabetes mellitus (DM) has been increasingly recognized over the past decades. Objective: The purpose of this review is to provide the reader with knowledge concerning the relationship between PD and DM. Many articles have been published in the English and Portuguese literature over the last 50 years examining the relationship between these two chronic diseases. Data interpretation is often confounded by varying definitions of DM, PD and different clinical criteria were applied to determine the prevalence, extent and severity of PD, levels of glycemic control and diabetes-related complications. Methods: This paper provides a broad overview of the predominant findings from research conducted using the BBO (Bibliografia Brasileira de Odontologia), MEDLINE, LILACS and PubMed for Controlled Trials databases, in English and Portuguese languages published from 1960 to October 2012. Primary research reports on investigations of relationships between DM/DM control, PD/periodontal treatment and PD/DM/diabetes-related complications identified relevant papers and meta-analyses published in this period. Results: 7This paper describes the relationship between PD and DM and answers the following questions: 1- The effect of DM on PD, 2- The effects of glycemic control on PD and 3- The effects of PD on glycemic control and on diabetes-related complications. Conclusions: The scientific evidence reviewed supports diabetes having an adverse effect on periodontal health and PD having an adverse effect on glycemic control and on diabetes-related complications. Further research is needed to clarify these relationships and larger, prospective, controlled trials with ethnically diverse populations are warranted to establish that treating PD can positively influence glycemic control and possibly reduce the burden of...

Cost-benefit of hospitalization compared with outpatient care for pregnant women with pregestational and gestational diabetes or with mild hyperglycemia, in Brazil / Custo-benefício da hospitalização comparada ao atendimento ambulatorial em gestantes com diabetes pré-gestacional e gestacional ou com hiperglicemia leve, no Brasil

CONTEXT AND OBJECTIVE: Pregnancies complicated by diabetes are associated with increased numbers of maternal and neonatal complications. Hospital costs increase according to the type of care provided. This study aimed to estimate the cost-benefit relationship and social profitability ratio of hospitalization, compared with outpatient care, for pregnant women with diabetes or mild hyperglycemia. STUDY DESIGN: This was a prospective observational quantitative study conducted at a university hospital. It included all pregnant women with pregestational or gestational diabetes, or mild hyperglycemia, who did not develop clinical intercurrences during pregnancy and who delivered at the Botucatu Medical School Hospital (Hospital das Clínicas, Faculdade de Medicina de Botucatu, HC-FMB) of Universidade Estadual de São Paulo (Unesp). METHODS: Thirty pregnant women treated with diet were followed as outpatients, and twenty treated with diet plus insulin were managed through frequent short hospitalizations. Direct costs (personnel, materials and tests) and indirect costs (general expenses) were ascertained from data in the patients' records and the hospital's absorption costing system. The cost-benefit was then calculated. RESULTS: Successful treatment of pregnant women with diabetes avoided expenditure of US$ 1,517.97 and US$ 1,127.43 for patients treated with inpatient and outpatient care, respectively. The cost-benefit of inpatient care was US$ 143,719.16, and outpatient care, US$ 253,267.22, with social profitability of 1.87 and 5.35, respectively. CONCLUSION: Decision-tree analysis confirmed that successful treatment avoided costs at the hospital. Cost-benefit analysis showed that outpatient management was economically more advantageous than hospitalization. The social profitability of both treatments was greater than one, thus demonstrating that both types of care for diabetic pregnant women had positive benefits.

CONTEXTO E OBJETIVO: Gestações complicadas pelo diabetes estão associadas com aumento de complicações maternas e neonatais. Os custos hospitalares aumentam de acordo com a assistência prestada. O objetivo foi calcular o custo-benefício e a taxa de rentabilidade social da hospitalização comparada ao atendimento ambulatorial em gestantes com diabetes ou com hiperglicemia leve. DESENHO DO ESTUDO: Estudo prospectivo, observacional, quantitativo, realizado em hospital universitário, sendo incluídas todas as gestantes com diabetes pregestacional e gestacional ou com hiperglicemia leve que não desenvolveram intercorrências clínicas na gestação e que tiveram parto no Hospital das Clínicas, Faculdade de Medicina de Botucatu, Universidade Estadual Paulista (HC-FMB-Unesp). MÉTODOS: Trinta gestantes tratadas com dieta foram acompanhadas em ambulatório e 20 tratadas com dieta e insulina foram abordadas com hospitalizações curtas e frequentes. Foram obtidos custos diretos (pessoal, material e exames) e indiretos (despesas gerais) a partir de dados contidos no prontuário e no sistema de custo por absorção do hospital e posteriormente calculado o custo-benefício. RESULTADOS: O sucesso do tratamento das gestantes diabéticas evitou o gasto de US$ 1.517,97 e US$ 1.127,43 para pacientes hospitalizadas e ambulatoriais, respectivamente. O custo-benefício da atenção hospitalizada foi US$ 143.719,16 e ambulatorial, US$ 253.267,22, com rentabilidade social 1,87 e 5,35 respectivamente. CONCLUSÃO: A análise "árvore de decisão" confirma que o sucesso dos tratamentos elimina custos no hospital. A relação custo-benefício indicou que o tratamento ambulatorial é economicamente mais vantajoso do que a hospitalização. A rentabilidade social de ambos os tratamentos foi maior que 1, indicando que ambos os tipos de atendimento à gestante diabética têm benefício positivo.

Morbilidad y mortalidad neonatal asociada a la diabetes gestacional / Neonatal morbidity and mortality asociated with gestational diabetes

Objetivo: Determinar la asociación de la morbilidad y mortalidad neonatal con la diabetes gestacional. Método: Estudio tipo cohortes. Se realizó un estudio en embarazadas desde diciembre de 2007 a noviembre de 2008 en el servicio de tococirugía del Hospital General Regional No. 1 de Querétaro, México, se formaron dos grupos de 71 pacientes, uno con diabetes gestacional y otro sin ella. El muestreo fue por cuota pareado por edad. En ambos grupos se midieron variables sociodemográficas, antecedentes obstétricos, vía de interrupción del embarazo, morbilidad y mortalidad neonatal. Los resultados se analizaron con Chi cuadrado y riesgo relativo con un poder alfa de 0,05. Resultados: La tasa de morbilidad en el grupo expuesto fue de 60 por ciento. Las variables que tuvieron significancia estadística fueron: la obesidad pregestacional (RR: 2,7), cesßrea (RR: 3,3), complicaciones metabólicas (RR: 10), morbilidad respiratoria (RR: 6,7), macrosomía (RR: 4,1), hipoglucemia (RR: 14,2) y taquipnea transitoria del recién nacido (RR: 7,7). La edad materna, sobrepeso gestacional, nivel socioeconómico, escolaridad, antecedentes de macrosómicos, de cesáreas y de malformaciones congénitas; malformaciones congénitas, bajo peso neonatal, prematurez, enfermedad de membrana hialina, hiperbilirru-binemia, hipocalcemia, mortalidad neonatal y la asfixia no tuvieron asociación significativa. La complicación metabólica más frecuente fue: hipoglucemia (17,2 por ciento). No hubo muertes perinatales. Conclusiones: El grupo expuesto estudiado mostró mayor morbilidad asociada a la diabetes gestacional que el grupo no expuesto, es necesario el diagnóstico temprano en mujeres con factores de riesgo para esta entidad y establecer un programa de tratamiento con vigilancia estrecha.

Objectives: To determine the association of neonatal morbidity and mortality with gestational diabetes. Methods: Study cohort. A study of pregnant women from December 2007 to November 2008 in the service of ginecology and obstetrics HGR No. 1 Querétaro, were divided into two groups of 71 patients, one gestational diabetic and one without it. The quota sampling was matched by age. In both groups were measured sociodemographic, obstetric history, via interruption of birth, neonatal morbidity and mortality. The results were analyzed with Chi square and relative risk with a power alpha of 0.05. Results: The morbidity rate in the exposed group was 60 percent. Variables that were statistically significant were: pregestational obesity (RR: 2.7), cesarean (RR 3.3), metabolic complications (RR 10), respiratory illness (RR: 6.7), macrosomia (RR: 4.1), hypoglycemia (RR: 14.2) and transient tachypnea of the newborn (RR: 7.7). Maternal age, gestational overweight, socioeconomic status, education, history of macrosomic, and cesarean birth defects, congenital malformations, low birth weight, prematurity, hyaline membrane disease, hyperbilirubinemia, hypocalcemia, and neonatal asphyxia had no significant association. The most common metabolic complication was hypoglycemia (17.2 percent). There were no perinatal deaths. Conclusions: The exposed group showed higher morbidity associated with gestational diabetes that the unexposed group, early screening is necessary in women with risk factors for this disease and establish a treatment program with close monitoring.

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.
