GDM

The goal of this clinical trial is to evaluate the effects of a couple-based collaborative lifestyle intervention among women with a history of gestational diabetes. The main questions it aims to answer are: Does the intervention improve body mass index and 2-hour plasma glucose after an oral glucose tolerance test? Does the intervention improve health behaviors, psychological well-being, self-efficacy, couple functioning, and life satisfaction? Researchers will compare a couple-based collaborative lifestyle intervention with a woman-only lifestyle intervention to determine whether adding spousal collaboration and support leads to greater improvements. Participants will: Receive healthy lifestyle education posts for 3 months. In the couple-based group, also receive instant messages on behavioral promotion and couple collaboration and support videos.

Gestational diabetes mellitus (GDM) is associated with an increased risk of childhood obesity and other adverse health outcomes. Early-life nutrition, particularly exclusive breastfeeding, plays an important role in reducing this risk. In Vietnam, infant feeding and childcare practices are strongly influenced by family members, including husbands, grandparents, and parents-in-law. The Healthy Habits During and After Gestational Diabetes (VALID III) trial aims to evaluate the effect of a co-created family-based health intervention on improving infant feeding practices and childhood body composition among children born to women with GDM. The intervention includes counseling, peer support, digital health components, educational materials, and follow-up support for nutrition, infant feeding practices, physical activity, and GDM management from pregnancy through 24 months after birth. Participants in the control group will receive standard care together with access to a GDM management website. The primary objective is to evaluate the effect of the intervention on the duration of exclusive breastfeeding during the first 180 days after birth. Secondary objectives include evaluating exclusive breastfeeding at 6 months, child fat mass index at 24 months, and broader maternal and child health and wellbeing outcomes.

ASPIRE will be a multi-site, prospective, two-part longitudinal, noninterventional observational cohort study of nulliparous singleton pregnant women to evaluate biomarkers from blood and ocular imaging for prediction of pregnancy complications \[i.e., preeclampsia (PE), fetal growth restriction (FGR), and gestational diabetes (GDM)\] and risk of adverse outcomes.

A Multicenter Prospective Cohort Study to Identify Risk Factors and Develop a Diagnostic Prediction Model for Gestational Diabetes Mellitus, and to Evaluate the Effectiveness of Multidisciplinary Precision Health Interventions (GLOW Plan)

This study aims to explore whether early intervention for high-risk groups of gestational hyperglycemia can improve insulin resistance and effectively prevent the occurrence of GDM, and evaluate which pathophysiological subtypes of GDM have the best effect on improving maternal and fetal adverse prognosis, so as to provide evidence for stratified management and individualized clinical intervention of high glucose groups in pregnancy

We wish to study the effect of a mothers sugar (glucose) control during pregnancy on her baby's sugar control after birth.

This study aims to comprehensively evaluate the multifaceted impacts of Lactobacillus rhamnosus LRa05 on patients with gestational diabetes. Initially, the study will investigate the effects of LRa05 on improving patients' blood glucose levels and gut microbiota. Additionally, the study will assess the impact of this strain on patients' blood lipid levels, inflammatory markers, and body mass index (BMI). Furthermore, the study will also focus on its effects on thyroid function, vaginal microbiota, and bile acid metabolism in patients with gestational diabetes.
