Could earlier testing for pregnancy diabetes prevent complications?
NCT ID NCT03523143
First seen Jul 02, 2026 · Last updated Jul 02, 2026
Summary
This trial investigates whether screening for gestational diabetes earlier in pregnancy (at 18-20 weeks instead of the usual 24-28 weeks) and providing prompt lifestyle advice and medication if needed can reduce complications such as large babies, C-sections, and high blood pressure. About 2,000 pregnant women in Taiwan are taking part, with half receiving early screening and half receiving standard care. The study compares outcomes for both mothers and babies.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- early screening and lifestyle intervention
- What this could lead to
- If early screening proves better, it could reduce complications like large babies, C-sections, and high blood pressure in pregnancy.
- What could go wrong
- This is a single-country trial, and early screening may not improve outcomes enough to change practice. Some women may receive unnecessary treatment.
