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 ¼ 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 ¼ 1.49-2.39) greater if the pregnant woman was obese, 4.6 times (95%CI ¼ 3.017-7.150) greater if she was a primigravida, and 5.2 times (95% CI ¼ 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.

This is a cross-sectional study, which evaluated race/color influences on unfavorable obstetric and neonatal outcomes. Logistic regression models were constructed to calculate the odds ratio and to examine maternal and neonatal risk. Black pregnant women prevailed with statistical significance among those with low schooling, previous hypertension, three or more living children and with occupation. Black pregnant women presented no greater risk in unfavorable outcomes. Race/color does not behave as a genetic or biological marker, but as a social construct, which can influence health conditions as a social determinant. KEYWORDS

Avaliar o tratamento utilizado e a classificação de peso de recém-nascidos (RN) de gestantes portadoras de Diabetes Mellitus Gestacional (DMG). Foi realizado um estudo transversal descritivo com gestantes portadoras de DMG, em gestação única, no período de abril de 2011 a fevereiro de 2016. Os dados avaliados foram o tipo de tratamento utilizado e a classificação de peso do RN. Foram avaliadas 893 gestantes. A dieta e a atividade física como única terapêutica foram utilizadas por 306 (34,3%), 366 (41%) necessitaram metformina, a associação de metformina e insulina foi necessária em 109 (12,2%) e utilizaram somente insulinoterapia 112 (12,5%) gestantes. Houve 27 (3,0%) RN pequenos para a idade gestacional (PIG), 687 (76,9%) RN adequados para a idade gestacional (AIG) e 179 (20,0%) RN grandes para a idade gestacional (GIG). A metformina foi a terapêutica mais utilizada e a maioria dos recém-nascidos foram AIG.

Objective To evaluate the factors associated with the need for insulin as a complementary treatment to metformin in pregnant women with gestational diabetes mellitus (GDM). Methods A case-control study was performed from April 2011 to February 2016 with pregnant women with GDM who needed complementary treatments besides diet and physical exercise. Those treated with metformin were compared with those who, in addition to metformin, also needed the combination with insulin. Maternal characteristics and glycemic control were evaluated. Multinomial logistic regression models were developed to evaluate the influence of different therapies on neonatal outcomes. Results A total of 475 pregnant women who needed pharmacological therapy were evaluated. Of these, 366 (77.05%) were submitted to single therapy with metformin, and 109 (22.94%) needed insulin as a complementary treatment. In the analysis of the odds ratio (OR), fasting glucose (FG) < 90 mg/dL reduced the odds of needing the combination (OR: 0.438 [0.235–0.815]; p = 0.009], as well as primiparity (OR: 0.280 [0.111–0.704]; p = 0.007]. In obese pregnant women, an increased chance of needing the combination was observed (OR: 2,072 [1,063–4,039]; p = 0,032). Conclusion Obesity resulted in an increased chance of the mother needing insulin as a complementary treatment to metformin, while FG < 90 mg/dL and primiparity were protective factors.

NascimeNto iB et al. 264Rev assoc med Objective: To identify the changes caused by dyslipidemia and obesity in pregnancy suggesting causes for premature birth, and the prognosis for the newborn. Method: Systematic review based on the Medline, Lilacs, Embase and Cochrane library databases between 1996 and 2016. The search for studies included the following keywords: "dyslipidemia, pregnancy, obesity, preterm birth." A protocol was programmed and a protocol for inclusion/exclusion of studies was implemented. Results: Of the 5,789 articles initially selected between March 1996 and July 2016, only 32 were in accordance with the established criteria. Of these, 28.12% discussed risk factors of prematurity; 37.50%, metabolic alterations and gestational dyslipidemia; 21.87%, dyslipidemic complications in preterm birth; and 12,50%, lipid metabolism, glycemic and placental transfer. Conclusion:There is a reduced adaptation of obese pregnant women to the metabolic changes of gestation. This favors dyslipidemic intercurrences in the mother, which, directly or indirectly, suggests the occurrence of premature births and high lipid transfer to the fetus. Therefore, preterm newborns, whose mothers were dyslipidemic during pregnancy, have greater risk of epicardial fat, both in early (first year of life) and in later (adult) phases of life.
