Objectives: To explore the association between maternal gestational diabetes mellitus (GDM) exposure and the development of autism spectrum disorder (ASD) in offspring.
Methods: A case-control study was conducted, recruiting 221 children with ASD and 400 healthy children as controls. Questionnaires and interviews were used to collect information on general characteristics of the children, socio-economic characteristics of the family, maternal pregnancy history, and maternal disease exposure during pregnancy. Multivariate logistic regression analysis was used to investigate the association between maternal GDM exposure and the development of ASD in offspring. The potential interaction between offspring gender and maternal GDM exposure on the development of ASD in offspring was explored.
Results: The proportion of maternal GDM was significantly higher in the ASD group compared to the control group (16.3% vs 9.4%, =0.014). After adjusting for variables such as gender, gestational age, mode of delivery, parity, and maternal education level, maternal GDM exposure was a risk factor for ASD in offspring (=2.18, 95%: 1.04-4.54, =0.038). On the basis of adjusting the above variables, after further adjusting the variables including prenatal intake of multivitamins, folic acid intake in the first three months of pregnancy, and assisted reproduction the result trend did not change, but no statistical significance was observed (=1.94, 95%: 0.74-5.11, =0.183). There was an interaction between maternal GDM exposure and offspring gender on the development of ASD in offspring (<0.001). Gender stratified analysis showed that only in male offspring of mothers with GDM, the risk of ASD was significantly increased (=3.67, 95%: 1.16-11.65, =0.027).
Conclusions: Maternal GDM exposure might increase the risk of ASD in offspring. There is an interaction between GDM exposure and offspring gender in the development of ASD in offspring.

Gestational diabetes is marked impaired glucose tolerance, poses various adverse outcomes including increased BMI and obesity. These outcomes results from excess lipid accumulation which is marked by elevated triglycerides. In GDM, placenta exhibits altered lipid metabolism, including reduced fatty acid oxidation and increased triglyceride accumulation.

Gestational diabetes mellitus (GDM), a common pregnancy disease, has long-term negative effects on offspring health. Epigenetic changes may have important contributions to that, but the underlying mechanisms are not well understood. Here, we report the influence of GDM on DNA methylation of offspring (GDF1) oocytes and the possible mechanisms.

The 'Developmental Origins of Health and Disease' (DOHaD) hypothesis postulates that exposures during critical periods of development and growth, including maternal hyperglycemia, can have significant consequences for short- and long-term health in offspring. The influence of fetal status on maternal (patho)physiology is less well understood but gaining attention. Fetal sex specifically may be an independent risk factor for a range of adverse pregnancy outcomes, including increased gestational diabetes mellitus (GDM) frequency with male fetuses in multi-ethnic populations.

Objective: Gestational diabetes mellitus (GDM) is a common medical complication of pregnancy that leads to adverse outcomes for both infants and pregnant people. Early detection and treatment can mitigate these negative outcomes. The COVID-19 pandemic strained healthcare and laboratory services, including GDM screening programs.

In utero exposure to gestational diabetes mellitus (GDM) is associated with adverse long-term outcomes. Little is known about how mothers perceive these outcomes and the support they need for optimal outcomes for their children. We aimed to explore how women perceive the risk of adverse outcomes for their children exposed to GDM and the support they require for their optimal health.
