Summary

This study tested whether sending text messages with links to evidence-based websites could help pregnant women be more physically active. Researchers enrolled 82 pregnant women and measured their activity with a FitBit. The goal was to see if this simple, low-cost approach is feasible and acceptable.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
physical activity text messages
What this could lead to
If successful, this approach could offer a simple, low-cost way to help pregnant women find reliable physical activity information online.
What could go wrong
This is a small feasibility study, not a large trial. It only tests whether the method works, not whether it improves health outcomes. Results may not apply to all pregnant women.
