Insights
Preterm children often struggle with executive function (EF) skills, impacting their learning and behavior. This study shows EF skills are crucial for functional outcomes in preterm children, suggesting potential for early intervention.
Area of Science:
- Neuroscience
- Developmental Psychology
- Pediatrics
Background:
- Preterm children face elevated risks for executive function (EF) deficits.
- These EF challenges are associated with later behavioral and academic difficulties.
- Understanding EF in preterm populations is critical for identifying at-risk individuals.
Purpose of the Study:
- To assess executive function (EF) skills in children aged 9-16 born preterm across varying gestational ages (GA).
- To determine the relationship between degree of prematurity and executive function (EF) abilities.
- To investigate the contribution of executive function (EF) to reading scores and parent-rated child functioning.
Main Methods:
- Compared preterm children (<36 weeks gestation) with full-term controls on EF, reading, and functional outcome measures.
- Utilized multiple regression models to analyze contributions to EF skills and functional outcomes.
- Controlled for age, gender, socioeconomic status (SES), and intelligence quotient (IQ).
Main Results:
- Preterm children exhibited poorer performance on complex planning and organization tasks compared to controls.
- Gestational age (GA) influenced EF skills, though this effect was mediated by IQ.
- Executive function (EF) significantly predicted parent-rated child function, independent of IQ.
- EF contributed to reading skills variance, but this was not significant when IQ was accounted for.
Conclusions:
- Executive function (EF) skills play a significant role in the functional outcomes of children born preterm.
- EF skills may serve as early indicators for learning and functional impairments in this high-risk group.
- Targeting EF interventions for preterm children warrants further investigation for improved developmental trajectories.
Background:
Preterm children are at risk for executive function (EF) problems, which have been linked to behavior and learning problems in full term children. In this study, we examine the relationship between EF and functional outcomes in preterm children.
Aim:
To evaluate (1) EF skills of 9- to 16-year-old children born across the spectrum of gestational age (GA), (2) relationship of degree of prematurity to EF skills, and (3) contributions of EF skills to two functional outcomes - reading scores and parent-rated child function.
Method:
Preterm children <36 weeks gestation (n=72) were compared to full term children (n=42) of similar age, gender and SES, on measures of EF, reading, and parent-ratings of child function. Multiple regression models evaluated contributions to EF skills and functional outcomes.
Results:
Compared to full term controls, preterm children had poorer EF performance on a complex planning and organization task and did not increase planning time as task difficulty increased. Their spatial memory capacity was not different. GA contributed to EF skills, but was mediated by IQ. EF contributed to the variance in reading skills but did not add to the variance in reading when IQ was considered. EF skills significantly contributed to the variance in parent-rated child function, but IQ did not.
Conclusion:
EF skills contribute to measures of functional outcome in this high-risk population. The use of EF skills as an early marker for learning and functional problems and as a target for intervention in children born preterm warrants future study.
