Early screening to find gestational diabetes in pregnancy

Early Detection of Gestational Diabetes Mellitus in Pregnancy: A Randomized Trial

Not applicable Interventional University of Massachusetts, Worcester · NCT05388643

This project tries a first-trimester blood screening to see if it finds gestational diabetes earlier in pregnant people at high risk.

What this trial studies

Gestational diabetes increases risks for both mothers and newborns and is typically screened for in the second trimester. This pilot randomized controlled trial will enroll 80 high-risk pregnant people before 12 weeks at UMass Memorial; half will receive a protocolized first-trimester serum biomarker screen and half will receive standard screening at 24–28 weeks with possible early screening at provider discretion. The study will test the feasibility and acceptability of implementing early screening and compare timing of detection and related maternal and neonatal outcomes. Investigators will use clinical data and participant feedback to refine the protocol for potential broader use.

Who should consider this trial

Good fit: Pregnant people aged 18 or older with a singleton pregnancy at or before 12 weeks, receiving prenatal care and planning delivery at UMMHC, who meet ACOG high-risk criteria and speak English or Spanish are ideal candidates.

Not a fit: People with preexisting diabetes, those unable to complete an oral glucose tolerance test, those on systemic steroids, or those planning care outside UMMHC are unlikely to benefit.

Why it matters

Potential benefit: If successful, earlier detection could allow earlier treatment and monitoring to reduce pregnancy and newborn complications.

How similar studies have performed: Prior work on first-trimester biomarker screening for gestational diabetes has shown mixed results, so this pilot focuses on feasibility and implementation.
