Gestational diabetes and health outcomes for mothers and babies

Understanding the Effects of Gestational Diabetes on Mother and Baby

Medical University of Graz · NCT07459907

This project will follow pregnant women with gestational diabetes to see how the condition affects mothers and their babies during pregnancy, delivery, and early postpartum.

What this trial studies

This prospective, single-center observational cohort will recruit pregnant women diagnosed with gestational diabetes after a positive 75 g oral glucose tolerance test, typically between gestational weeks 24 and 28. Participants will attend two study visits during pregnancy, provide clinical samples at delivery, and complete a postpartum visit 8–12 weeks after birth, with clinical data, physical measurements, questionnaires, and biological samples collected from mothers and infants. Approximately 100 women will be enrolled per year at the Department of Obstetrics and Gynecology of the Medical University of Graz, and women with major fetal anomalies or diagnosis after 32 weeks are excluded. The collected data and biosamples are intended for comprehensive phenotyping to help define mechanisms and early-life outcomes associated with gestational diabetes.

Who should consider this trial

Good fit: Pregnant women aged 18 years or older with an ongoing pregnancy before 32 weeks and a positive 75 g oral glucose tolerance test are ideal candidates.

Not a fit: Women diagnosed after the 32nd gestational week, pregnancies with major fetal anomalies, or those unwilling to attend study visits or provide samples are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, the project could improve understanding of how gestational diabetes affects short- and long-term health and inform better prevention or follow-up strategies for mothers and children.

How similar studies have performed: Other longitudinal gestational diabetes cohorts have provided useful insights into maternal and offspring cardiometabolic risk, so this approach is established though mechanisms remain incompletely understood.
