Summary

This study tested a phone-based program called MommyCheckup to see if it helps pregnant women who drink alcohol cut back or stop. The program includes a short motivational video and tailored text messages. Researchers enrolled 384 pregnant women across three states to see if the app leads to healthier births and less alcohol use.

What this could mean

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

Active substance
electronic brief intervention (e-SBI) called MommyCheckup
What this could lead to
If it works, this could provide a scalable tool to help pregnant women reduce alcohol use and lower the risk of fetal alcohol disorders.
What could go wrong
This is a completed trial with self-reported outcomes, which may not be fully reliable. The intervention is behavioral, so results may vary across different populations.
