Executive function deficits mediate the association between very preterm birth and behavioral problems at school-age

Area of Science:

• Neuroscience
• Developmental Psychology
• Pediatrics

Background:

• Children born very preterm face higher risks for executive function deficits.
• These deficits are associated with social, emotional, and attentional challenges.
• This study examines the link between executive function and behavioral problems in school-aged children born very preterm.

Purpose of the Study:

• To investigate if executive function deficits contribute to behavioral problems in very preterm children.
• To quantify the mediating role of executive function in the relationship between preterm birth and behavioral issues.

Main Methods:

• Compared 38 very preterm children/adolescents with 41 term-born peers at mean age 12.9 years.
• Assessed executive functions (working memory, planning, flexibility, fluency) and behavioral problems (SDQ).
• Used mediation analysis to determine the effect of preterm birth on behavior, with executive function as a mediator.

Main Results:

• Very preterm children showed poorer executive function abilities (d=0.62, p=0.005).
• Parents reported more behavioral problems in very preterm children (SDQ Total Difficulties Score, d=0.54, p=0.01).
• Executive function abilities significantly mediated the effect of preterm birth on behavioral problems (F(2, 76)=6.42, p=0.002).

Conclusions:

• Executive function deficits may partly explain increased behavioral symptoms in school-aged very preterm children.
• Highlights the need for ongoing monitoring of executive function development in very preterm children.
• Emphasizes the importance of early intervention and tailored support for optimal development.
