Insights
Children born preterm face significant academic challenges, particularly in math and reading. Bronchopulmonary dysplasia increases the risk for poor academic outcomes in these vulnerable children.
Area of Science:
- Neonatal Medicine
- Developmental Psychology
- Educational Psychology
Background:
- Neonatal care advances reduce preterm mortality but not morbidity.
- Academic performance is a key indicator of outcomes for preterm children.
- Understanding academic difficulties is crucial for targeted interventions.
Purpose of the Study:
- To assess academic performance in preterm children born during the antenatal steroids and surfactant era.
- To investigate the influence of perinatal and demographic factors on academic outcomes.
- To identify specific academic challenges faced by preterm populations.
Main Methods:
- Systematic review and meta-analysis of peer-reviewed articles from PubMed, Web of Science, and PsycINFO.
- Inclusion of cohort studies comparing preterm children (<37 weeks gestation) to full-term controls (≥5 years old).
- Analysis of standardized academic scores and special educational needs, with meta-regression for moderating factors.
Main Results:
- Preterm children scored significantly lower in arithmetic (0.71 SD), reading (0.44 SD), and spelling (0.52 SD) compared to full-term peers.
- Preterm children were 2.85 times more likely to require special educational assistance.
- Bronchopulmonary dysplasia accounted for 44% of the variance in academic performance.
Conclusions:
- Preterm children born in the modern era exhibit substantial academic difficulties.
- Bronchopulmonary dysplasia is a significant risk factor for poor academic achievement in preterm infants.
- Early identification and support are essential for preterm children with academic challenges.
Background:
Advances in neonatal healthcare have resulted in decreased mortality after preterm birth but have not led to parallel decreases in morbidity. Academic performance provides insight in the outcomes and specific difficulties and needs of preterm children.
Objective:
To study academic performance in preterm children born in the antenatal steroids and surfactant era and possible moderating effects of perinatal and demographic factors.
Design:
PubMed, Web of Science and PsycINFO were searched for peer-reviewed articles. Cohort studies with a full-term control group reporting standardised academic performance scores of preterm children (<37 weeks of gestation) at age 5 years or older and born in the antenatal steroids and surfactant era were included. Academic test scores and special educational needs of preterm and full-term children were analysed using random effects meta-analysis. Random effects meta-regressions were performed to explore the predictive role of perinatal and demographic factors for between-study variance in effect sizes.
Results:
The 17 eligible studies included 2390 preterm children and 1549 controls. Preterm children scored 0.71 SD below full-term peers on arithmetic (p<0.001), 0.44 and 0.52 SD lower on reading and spelling (p<0.001) and were 2.85 times more likely to receive special educational assistance (95% CI 2.12 to 3.84, p<0.001). Bronchopulmonarydysplasia explained 44% of the variance in academic performance (p=0.006).
Conclusion:
Preterm children born in the antenatal steroids and surfactant era show considerable academic difficulties. Preterm children with bronchopulmonarydysplasia are at particular risk for poor academic outcome.
