NCT ID NCT07223112
First seen Jun 26, 2026 · Last updated Aug 26, 2026 · Updated 3 times
Summary
This study tests a program called 'Sit Less, Move More' for pregnant women. It uses health coaching, text messages, and a Fitbit to help women increase physical activity and reduce sitting time. The goal is to see if this approach improves health for mothers and babies. Sixty women in early pregnancy will take part.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- behavioral intervention: health coach sessions, SMS texts, and Fitbit activity tracker
- What this could lead to
- If it works, this could show a simple way to help pregnant women be more active, potentially reducing risks like high blood pressure and preterm birth.
- What could go wrong
- This is a small early study with only 60 participants, so results may not apply to everyone. The intervention relies on motivation and may not work for all women.
