Insights
Most premature infants are school-ready, but male gender, chronic lung disease, and low socioeconomic status are risk factors. Socioeconomic status is the most significant predictor of school readiness in these children.
Area of Science:
- Neonatal care and developmental pediatrics.
- Public health and socioeconomic factors in child development.
Background:
- Advances in neonatal care have increased survival rates for premature infants.
- However, their school readiness and associated risk factors remain understudied.
- This study addresses the need to understand school preparedness in this vulnerable population.
Purpose of the Study:
- To assess the school readiness of children born prematurely.
- To identify risk factors associated with lower school readiness in this cohort.
Main Methods:
- A prospective cohort study followed 135 surviving premature infants (mean gestational age 27.5 weeks).
- Children underwent neurodevelopmental, health, and socioeconomic status assessments around age 5.7 years.
- A 4-level school-readiness score was derived from standardized assessments and medical/sensory evaluations.
Main Results:
- 67% of the children were deemed school-ready.
- Risk factors for lower school readiness included male gender, chronic lung disease, and severe brain injury (intraventricular hemorrhage/periventricular leukomalacia).
- Low socioeconomic status was the most significant predictor of school readiness.
Conclusions:
- While neonatal morbidities impact school readiness, the social environment plays a more critical role.
- Interventions addressing socioeconomic factors may be more effective than those solely targeting neonatal issues for improving school performance.
Objective:
With advances in neonatal care, more children born prematurely are successfully reaching school age. It is unknown how many will be ready for school and what factors affect school readiness. Our objective was to assess readiness of children born prematurely for entry into public school, and determine risk factors associated with lack of school readiness in this population.
Methods:
This was a single-center prospective cohort study. Follow- up data were collected for 135 of 167 (81%) surviving premature infants with RDS requiring surfactant-replacement therapy. The children were seen between July 2005 and September 2006 (average age: 5.7 +/- 1.0 years) and underwent standardized neurodevelopmental and health assessments and socioeconomic status classification. A 4-level school-readiness score was constructed by using each child's standardized scores on assessments of basic concepts (Bracken School-Readiness Assessment), perceptual skills (Visual-Motor Integration Test), receptive vocabulary (Peabody Picture Vocabulary Test, Third Edition), daily living functional skills (Pediatric Functional Independence Measure), and presence of sensory impairments or autism. Proportional odds models were used to identify risk factors predicting lower school-readiness levels.
Results:
Mean birth weight was 1016 +/- 391 g, and mean gestational age was 27.5 +/- 2.6 weeks. Ninety-one (67%) children were school-ready. Using multivariate analysis, male gender, chronic lung disease, and severe intraventricular hemorrhage or periventricular leukomalacia were associated with lower school-readiness levels. However, the most powerful factor determining school-readiness level was low socioeconomic status.
Conclusion:
Interventions targeting neonatal morbidities may be much less effective at improving overall performance at school age compared with the effect of the impoverished social environment.
