AI Article Synopsis
- - The study aimed to determine if maternal pregestational diabetes (PGDM) mediates the relationship between obesity and congenital heart defects (CHDs) in infants.
- - Researchers analyzed data from 53,708 mother-infant pairs and found that maternal obesity significantly increased the risk of CHDs, with PGDM showing a partial mediating effect (24.83%).
- - The findings suggest that addressing maternal obesity and diabetes could be important for reducing the risk of CHDs in infants.
Article Abstract
Aims/introduction: We aimed to explore whether the association between obesity and congenital heart defects (CHDs) can be mediated by maternal pregestational diabetes (PGDM).
Materials And Methods: We included 53,708 mother-infant pairs with deliveries between 2017 and 2019 from the Birth Cohort in Shenzhen. Mothers were categorized into four groups: the underweight group (body mass index [BMI] <18.5), normal weight group (18.5 ≤ BMI < 24), overweight group (24 ≤ BMI < 28) and obesity group (BMI ≥28). Multivariable logistic regression models were used to evaluate the association between BMI and CHDs. Mediation analysis was used to confirm the effect of PGDM on the association between maternal obesity and CHDs.
Results: The proportion of obese individuals in the Birth Cohort in Shenzhen was 2.11%. Overall, 372 (0.69%) infants were diagnosed with CHDs. Maternal obesity was associated with an increased risk of CHDs (odds ratio 1.97, 95% confidence interval 1.14-3.41). The mediation effect of PGDM on the association between maternal obesity and CHDs was significant (odds ratio 1.18, 95% confidence interval 1.06-1.32). The estimated mediation proportion was 24.83%.
Conclusions: Maternal obesity was associated with increased risk for CHDs, and PGDM partially mediated the association between maternal obesity and CHDs.

This study aimed to assess the strengths, limitations, opportunities, and threats presented by diabetes-in-pregnancy. We review the improvements in maternal and fetal mortality since the advent of insulin therapy, evaluate current health challenges, and identify opportunities for preventing increased mortality due to diabetes-in-pregnancy. Prior to 1922, women with type 1 diabetes mellitus (T1DM) of childbearing age were discouraged from becoming pregnant as the maternal and fetal/neonatal mortality rates were extremely high.

Purpose: We aimed to determine fetal liver perfusion in PGDM and GDM pregnancies and to assess the relation of ductus venosus (DV) shunt fraction with adverse pregnancy outcomes.
Methods: We conducted a prospective longitudinal observational study including 188 pregnant women: group I-patients with pregestational DM (PGDM, n = 86), group II-patients with gestational DM (GDM, n = 44), group III-control (n = 58). The patients included in the study underwent ultrasound examination at 30-40 weeks of pregnancy.

Proper nutrition is essential during pregnancy to ensure an adequate supply of nutrients to the foetus and adequate maternal weight gain. In pregnancy complicated by diabetes (both gestational and pre-gestational), diet in terms of both the intake and quality of carbohydrates is an essential factor in glycaemic control. Maternal BMI at conception defines the correct weight increase during gestation in order to reduce maternal-foetal complications related to hypo- or hyper-nutrition.

Background Maternal diabetes mellitus (DM) is a known risk factor for congenital heart diseases (CHDs), which are of significant concern to infants born to diabetic mothers. Compared to newborns born to non-diabetic mothers, infants born to diabetic mothers had a higher overall risk of developing congenital malformations. This association has a complex pathophysiology that includes genetic predispositions, metabolic abnormalities, and environmental factors during key stages of fetal development.

Objective: To evaluate the frequency of adverse maternal and neonatal outcomes associated with maternal obesity in a Hispanic population. We hypothesized that obesity confers a dose-dependent risk associated with these outcomes.
Study Design: This was a retrospective cohort study of singleton pregnancies delivered between 24 and 42 weeks gestation at an urban county hospital between 2013 and 2021.
