What this trial studies

This clinical trial evaluates the effectiveness of SmartMom, a mobile health program that sends evidence-based text messages to pregnant individuals to promote healthy behaviors. Participants in the intervention group will receive three messages per week focused on prenatal education, while the control group will receive general interest messages that do not encourage behavior change. The study aims to assess improvements in knowledge about healthy pregnancy, mental health measures, and overall maternal and fetal outcomes. The trial is designed to provide insights into how mobile health interventions can enhance prenatal care.

Why it matters

Potential benefit: If successful, this program could significantly improve health outcomes for pregnant individuals and their babies by promoting positive health behaviors.

How similar studies have gone: Other studies have shown success with mobile health interventions in promoting health behaviors, making this approach promising yet still innovative.
