Does low blood sugar at birth affect toddler development?
NCT ID NCT04875624
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed study followed 126 babies born at 35 weeks or later who were at risk for low blood sugar (hypoglycemia). Researchers compared those who had low blood sugar in their first day of life with those who did not, testing their thinking, movement, and language skills at 18 to 24 months old. The goal was to see if brief low blood sugar affects long-term development.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this study could clarify whether brief neonatal hypoglycemia affects long-term brain development, guiding future monitoring and care.
- What could go wrong
- This is an observational study with a small sample (126 infants) and no intervention, so it cannot prove cause and effect. Results may not apply to all at-risk newborns.

Who is studied
This is a cross-sectional study evaluating neurodevelopmental outcome at 18 to 24 months of SGA/late preterm neonates who received risk-based screening for hypoglycemia and were found to be either normoglycemic or hypoglycemic during hospitalization. Eligible subjects will be identified via electronic health record search, and their hypoglycemia risk factors will be verified together with glycemia status. Parents of eligible subjects will be contacted via phone and invited for research participation; Bayley Scales of Infant and Toddler Development, Fourth Edition (Bayley-4) will be administered by one of the 2 blinded examiners who are unaware of neonatal glycemia status. Bayley-4 examines Cognitive, Language, Motor, Social-Emotional and Adaptive Behavior domains of development .
