Background: Macrosomia at birth is associated with maternal hyperglycemia and leads to subsequent susceptibility to obesity, abnormal glucose metabolism, hypertension, and dyslipidemia in offspring. Epigenetic reprogramming has been reported to be involved in the development of human diseases caused by suboptimal environmental or nutritional factors. The study was aiming to explore epigenetic mechanism influences on macrosomic infants exposed to intrauterine hyperglycemia. We performed a genome-wide analysis of DNA methylation in cord blood from macrosomic infants born to women with gestational diabetes in order to identify genes related to fetal growth or early adipose tissue development.Methods: To analyze the epigenetic patterns in umbilical cord blood in gestational diabetes mellitus (GDM), we collected umbilical cord blood from women with GDM (mean pregestational BMI of 24.4 kg/m2 and mean neonatal birth weight of 4366 g) and normal glucose-tolerant women (mean pregestational BMI of 19.8 kg/m2 and mean neonatal birth weight of 3166 g). Differentially methylated genes in the GDM group were identified using the Infinium HumanMethylation450 BeadChip array.Results: A total of 1251 genes were differentially methylated compared to the controls (p < .01). The methylation microarray data showed that two specific CpG sites (cg12604331 and cg08480098) in the gene body of ARHGEF11 were significantly hypomethylated in the cord blood in macrosomic infants. Altered DNA methylation levels of ARHGEF11 were negatively correlated with glucose levels and neonatal birth weight.Conclusions: Exposure to adverse intrauterine environments can alter fetal development, such as by affecting the nutritional status of the fetus. Such exposure can also result in significant epigenetic modifications, including DNA methylation, which could serve as a potential marker for nutrition and metabolic conditions at the neonatal stage or even in the adult.

Purpose: Gestational diabetes mellitus (GDM) may share similar mechanisms with type 2 diabetes and obesity. In the current study, we aimed to verify twenty genes reported to be associated with type 2 diabetes and obesity in the Chinese GDM population.Methods: Pregnant women aged 20-49 years at 24-28 gestational weeks were recruited and 556 cases and 445 controls were enrolled in the study. The genotyping of single nucleotide polymorphisms (SNPs) was performed on peripheral blood samples.Results: We discovered that GDM was associated with rs945508 (OR = 1.368, 95% CI = 1.080-1.732, p = .009), rs10804591 (OR = 1.446, 95% CI = 1.192-1.754, p < .001), rs10245353 (OR = 1.204, 95% CI = 1.006-1.441, p = .043) and rs1552224 (OR = 1.451, 95% CI = 1.071-1.964, p = .016).Conclusions: We found that four SNPs associated with type 2 diabetes and obesity may also increase the risk of developing GDM in the Chinese population. Among these SNPs, we report for the first time that rs945508 in ARHGEF11, rs10804591 in PLXND1 and rs10245353 in NFE2L3 were associated with GDM. [ABSTRACT FROM AUTHOR]- Published

Background: The study aimed to evaluate whether exercise intervention can be applied to pregnant women with gestational diabetes mellitus (GDM) for controlling gestational weight gain (GWG) and combating GDM-related outcomes.Methods: Retrospective six months analysis of 14,168 single pregnant women without diabetes from 15 hospitals in Beijing in 2013. Each participant's demographic data, interventions condition and medical information were collected individually by questionnaires and relying on medical records. The level of statistical significance was set equal to 0.05.Results: 2750 (19.4%) pregnant women were diagnosed with GDM, 74.9% of them received exercise intervention during pregnancy, and the starting time was 25.8 ± 3.7 gestational weeks. Women with GDM with exercise intervention (GDM-E) had the lowest BMI increase during late and mid-pregnancy than women with GDM without exercise intervention (GDM-nE) (2.05 ± 1.32 kg/m(2) vs. 2.40 ± 1.30 kg/m(2), p < 0.01) and non-GDM women (2.05 ± 1.32 kg/m(2) vs. 2.77 ± 1.21 kg/m(2), p < 0.01). Moreover, GDM-E group experienced a significantly lower risk of preterm birth (5.58% vs. 7.98%, p < 0.001), low birth weight (1.03% vs. 2.06 %, p < 0.001) and macrosomia (9.51 % vs. 11.18%, p > 0.05) than GDM-nE group. After including dietary factors in the analysis, women with GDM without either dietary or exercise intervention (GDM-nDnE) had the highest risk of preterm birth(OR = 1.64, 95 % CI, 1.14-2.36), while women with GDM with dietary intervention only (GDM-DnE) had the highest risk of low birth weight (OR = 3.10, 95 % CI, 1.23-7.81). However, women with GDM with both dietary and exercise intervention had the lowest rate of macrosomia.Conclusion: Exercise intervention is a suitable non-invasive therapeutic option that can be readily applied to manage weight gain and improve pregnancy outcomes in women with GDM.

Aims: To evaluate the importance and usefulness of fasting plasma glucose (FPG) in the first trimester in predicting adverse pregnancy outcomes.Methods: A retrospective study of 22,398 singleton pregnancies was conducted. Participants were divided into subgroups according to first-trimester FPG (low FPG, FPG < 5.1 mmol/L; medium FPG, 5.1 mmol/L ≤ FPG < 5.6 mmol/L; high FPG, 5.6 ≤ FPG < 7.0 mmol/L) and oral glucose tolerance test(OGTT) results (normal and abnormal) during pregnancy. Patient characteristics and risk of adverse pregnancy outcomes were compared. Then, the whole population of women with abnormal OGTT served as a reference, and the relative risks of maternal and neonatal complications in normal OGTT women were analyzed by categorical analyses and logistic regression. Subgroup analyses were performed according to pre-pregnancy body mass index (BMI).Results: The frequency of adverse pregnancy outcomes increased with increasing FPG levels during the first trimester, regardless of OGTT results. High FPG + Abnormal OGTT had the worst outcome. Compared to the whole population of women with abnormal OGTT, Normal OGTT + Medium FPG showed the same risk of PIH and macrosomia. Normal OGTT + High FPG showed the same risk of PIH, macrosomia as well as LGA and preterm birth. Additionally, Normal OGTT + Medium FPG + BMI ≥ 24 kg/m2 showed significantly higher risk of PIH (OR = 1.867, 1.245-2.800), macrosomia (OR = 1.748, 1.304-2.344) and LGA (OR = 1.274, 1.019-1.593). Furthermore, the OR value for PIH was 3.759 (1.680-8.412) in Normal OGTT + High FPG + BMI ≥ 24 kg/m2 compared to women with abnormal OGTT.Conclusions: First-trimester FPG values can help identify women at increased risk for adverse pregnancy outcomes. Increased attention and management should be given to women with early pregnancy FPG ≥ 5.10 mmol/L despite a normal OGTT, especially if their BMI ≥ 24 kg/m2. [ABSTRACT FROM AUTHOR]- Published
