Official title: Prevention of Developmental Delay and Xylitol (PDDaX) Study
Run by University of Washington · NCT05361122 · Data updated 2026-11-12
This study is testing if taking xylitol during pregnancy helps with the brain development of children aged 4 to 8 years, comparing two different ways to measure their progress.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are children aged 4-8 years who were born during the previous trial and whose parents can provide consent.
✕Probably not a fit
Children whose parents are unable to provide consent or who are unwilling to participate will not benefit from this study.

What this trial studies
This study aims to assess the effectiveness of the Malawi Developmental Assessment Tool (MDAT) for evaluating neurodevelopment in children aged 4-8 years, comparing it to the more complex Kaufman Assessment Battery for Children-II (KABC-II). It will involve 1,000 children, half of whom were born preterm and half term, to determine the impact of maternal xylitol exposure during pregnancy on various neurodevelopmental outcomes. Participants will undergo multiple neurodevelopmental tests to evaluate cognitive, executive function, and social-emotional skills. The study is conducted in Malawi, leveraging a previous trial that enrolled a large number of pregnant women.
Why it matters
Potential benefit: If successful, this study could provide insights into the benefits of xylitol during pregnancy for improving neurodevelopmental outcomes in children.
How similar studies have gone: While the approach of using xylitol during pregnancy is innovative, similar studies have not been widely conducted, making this a potentially novel investigation.
