NCT ID NCT07172880
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study follows 800 mothers and their babies to see if how much a pregnant person sits, moves, and sleeps affects the child's weight and heart disease risk up to age 2. Researchers will track activity with monitors and measure baby growth. The goal is to find out if changing daily habits during pregnancy could help prevent obesity and heart problems in children.

- What this could lead to
- If successful, this could point toward simple lifestyle changes during pregnancy that might lower a child's risk of obesity and heart disease later in life.
- What could go wrong
- This is an observational study, not a treatment trial. It can show links but not prove cause and effect. Results may not apply to all populations.
