NCT ID NCT02924636
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested an online personalized program for pregnant women with obesity to help them gain the right amount of weight and reduce the need for delivery interventions like C-sections or forceps. Over 800 women participated, using a secure website to communicate with dietitians and lifestyle coaches. The goal was to see if this digital support could improve birth outcomes.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ePPOP-ID program (online personalized behavioral intervention with dietitian and lifestyle coach support)
- What this could lead to
- If successful, this could offer a simple, scalable online tool to help pregnant women with obesity gain a healthier amount of weight and lower the chance of needing a C-section or assisted delivery.
- What could go wrong
- This is a completed study, but the intervention is behavioral and results may vary. It may not work for everyone, and the benefits might be modest. No major risks are expected beyond those of standard pregnancy care.
