About this study

The goals of this study are to: evaluate and validate the low-cost, transportable, easily-administered Malawi Developmental Assessment Tool (MDAT) for neurodevelopmental assessment of children aged 4-8 years old in Malawi, as compared to the gold-standard yet more cumbersome and costly Kaufman Assessment Battery for Children-II (KABC-II) among (1) n=500 formerly preterm children and (2) n=500 formerly term children. Additionally, we will evaluate the effects of gestational xylitol exposure compared to a lack of gestational xylitol exposure on neurodevelopmental outcomes of children aged 4-8 years old in Malawi through the following four neurodevelopmental tests: (3) KABC-II (cognitive outcomes), (4) EF Touch (executive functions), (5) Strengths and Difficulties Questionnaire (social-emotional outcomes), and (6) MDAT (motor and cognitive outcomes). The researchers will leverage subjects who completed the parent Prevention of Prematurity and Xylitol Trial, which enrolled 10069 pregnant individuals in Malawi and demonstrated a significant 24% reduction in incidence of preterm birth and low birthweight offspring in gravidae who chewed xylitol-containing chewing gum compared to those who did not. By ensuring that these offspring did not have higher rates of neurodevelopmental impairment, the study will promote promising multi-center international and domestic trial evaluating the impact of xylitol-containing chewing gum use and optimal dosage during pregnancy.
