Cerebral palsy and intrauterine growth

Area of Science:

• Neonatalogy
• Neurology
• Developmental Pediatrics

Background:

• Cerebral palsy (CP) is a leading cause of childhood motor disability.
• Intrauterine growth, assessed via birth weight for gestational age, is a key indicator of fetal well-being.
• The relationship between abnormal fetal growth and CP risk requires further elucidation.

Purpose of the Study:

• To examine the association between birth weight for gestation and cerebral palsy prevalence.
• To investigate sex-specific and severity-specific risk patterns of cerebral palsy related to intrauterine growth.
• To explore the implications of intrauterine growth monitoring for predicting fetal health and CP risk.

Main Methods:

• Utilized birth weight for gestational age as a proxy for intrauterine growth.
• Analyzed the prevalence of cerebral palsy across a spectrum of infant sizes at birth.
• Compared risk patterns between male and female infants and across different CP severity levels.

Main Results:

• Cerebral palsy prevalence exhibited a reversed J-shaped relationship with birth weight for gestation.
• Significantly elevated risks were observed for infants both lighter and heavier than the optimal size.
• Distinct patterns of size-at-birth specific CP risk were identified for males versus females and for severe versus milder CP cases.

Conclusions:

• Abnormal intrauterine growth, indicated by deviations in birth weight for gestation, is strongly associated with increased cerebral palsy risk.
• Sex and CP severity modify the relationship between fetal growth and neurodevelopmental outcomes.
• Serial monitoring of intrauterine growth may serve as a valuable clinical tool for assessing fetal health and identifying at-risk infants.
