Intellectual performance in young adult males born small for gestational age

Area of Science:

• Pediatric Neurology
• Developmental Pediatrics
• Human Growth and Development

Background:

• Children born small for gestational age (SGA) exhibit an elevated risk for neurological dysfunction.
• Understanding factors influencing long-term neurodevelopmental outcomes in SGA individuals is critical.

Purpose of the Study:

• To investigate intellectual performance in early adulthood among individuals born SGA.
• To specifically assess the impact of catch-up growth in height on intellectual outcomes in SGA children.

Main Methods:

• Utilized data from the Swedish Birth Register for gestational age and birth size information.
• Extracted adult height and intellectual performance data from the Swedish Conscript Register.
• Analyzed the correlation between birth parameters, catch-up growth, and adult intellectual performance.

Main Results:

• Low birth weight, length, and head circumference were associated with poorer intellectual and psychological performance in males born SGA.
• Very low gestational age independently increased the risk of subnormal intellectual outcomes.
• Absence of catch-up growth to a height above -2 SDS was the most significant predictor of adverse intellectual performance in SGA individuals.

Conclusions:

• Catch-up growth in height is a critical factor for neurodevelopmental recovery in children born SGA.
• Early identification and intervention to promote adequate growth are essential for mitigating neurological risks in SGA populations.
