Four- to seven-year evaluation in two groups of small-for-gestational age infants
Insights
Maternal hypertensive disease in pregnancy impacts neonatal development. Early delivery with lung maturity and monitored birth improves outcomes for small-for-gestational age infants in these cases.
Area of Science:
- Neonatal Development
- Perinatal Medicine
- Obstetrics
Background:
- Small-for-gestational age (SGA) neonates face developmental challenges.
- Maternal hypertensive disorders can affect fetal growth and neurodevelopment.
- Understanding developmental trajectories in SGA infants is crucial for early intervention.
Purpose of the Study:
- To assess intellectual and neurologic development in SGA neonates at 4-7 years of age.
- To compare developmental outcomes between SGA infants born to mothers with and without hypertensive disease.
- To identify factors influencing neurodevelopmental outcomes in SGA populations.
Main Methods:
- Longitudinal follow-up of 55 small-for-gestational age neonates.
- Developmental testing at 4 to 7 years of age.
- Comparison of outcomes based on maternal hypertensive disease status.
Main Results:
- Infants of mothers with hypertensive disease (Group A) generally scored better on developmental tests than Group B (no hypertensive disease).
- Within Group B, heavier, more mature neonates scored higher. In contrast, lighter, earlier-delivered neonates in Group A performed better, suggesting terminal compromise.
- Major neurologic problems were more frequent in Group A, indicating higher intrapartum vulnerability.
Conclusions:
- Earlier delivery, once lung maturity is achieved, followed by closely monitored delivery, is recommended for Group A (hypertensive disease) to enhance long-term outcomes.
- Maternal hypertensive disease presents a complex interplay with SGA neonatal development.
- Targeted interventions and delivery timing are critical for optimizing neurodevelopmental trajectories in at-risk SGA infants.
Abstract:
Fifty-five small-for-gestational age neonates were tested for intellectual and neurologic development at 4 to 7 years of age. When infants of mothers who had hypertensive disease (Group A) were compared with those who had no such disease (Group B), it was found that Group A scored generally better on developmental testing than Group B. Within Group B, it was found that heavier neonates of more advanced gestational ages tested higher unlike Group A where lighter neonates delivered earlier tested better, indicating terminal compromise in this group. Major neurologic problems were found more commonly in Group A than Group B, indicating a greater intrapartum vulnerability. It is concluded that in Group A, earlier delivery after the establishment of lung maturity followed by fully monitored delivery would result in better long-term outcome.
