Insights
Children born at early term (37-38 weeks) and late preterm (34-36 weeks) have a higher risk of poorer school performance at age 5. This educational achievement gap persists even after accounting for other factors.
Area of Science:
- Pediatric Health
- Educational Psychology
- Public Health
Background:
- Gestational age at birth is a critical factor influencing child development.
- Previous research indicates potential developmental differences in preterm infants.
- Understanding early educational outcomes is vital for timely interventions.
Purpose of the Study:
- To compare the school performance at age 5 years across different gestational age categories.
- To assess educational achievement in children born full term versus early term, late preterm, moderately preterm, and very preterm.
- To identify risks associated with non-full term births on early academic success.
Main Methods:
- Utilized the UK Millennium Cohort Study, a population-based cohort.
- Included 7,650 children born in 2000-2001, assessed in 2006.
- School performance measured by the Foundation Stage Profile (FSP) at the end of the first school year.
Main Results:
- 51% of full-term infants did not reach a good level of overall achievement, increasing with prematurity (up to 66% in very preterm).
- Early term and late preterm births showed an elevated risk of poorer achievement (aRR 1.05 and 1.12, respectively) compared to full term.
- Similar negative effects were observed in mathematical, physical, and creative development assessments.
Conclusions:
- Late preterm and early term births are linked to increased risks of poorer educational outcomes at age 5.
- These findings highlight the importance of considering gestational age in early childhood development.
- While risks exist, the effects of early/late preterm birth were smaller than other identified risk factors.
Objective:
To compare school performance at age 5 years in children born at full term (39-41 weeks gestation) with those born at early term (37-38 weeks gestation), late preterm (34-36 weeks gestation), moderately preterm (32-33 weeks gestation) and very preterm (<32 weeks gestation).
Design:
Population-based cohort (UK Millennium Cohort Study).
Participants:
Seven thousand six hundred and fifty children born in 2000-2001 and attending school in England in 2006.
Methods:
School performance was measured using the foundation stage profile (FSP), a statutory assessment by teachers at the end of the child's first school year. The FSP comprises 13 assessment scales (scored from 1 to 9). Children who achieve an average of 6 points per scale and at least 6 in certain scales are classified as 'reaching a good level of overall achievement'.
Results:
Fifty-one per cent of full term children had not reached a good level of overall achievement; this proportion increased with prematurity (55% in early term, 59% in late preterm, 63% in moderately preterm and 66% in very preterm children). Compared with full term children, an elevated risk remained after adjustment, even in early term (adjusted RR 1.05, 95% 1.00 to 1.11) and late preterm children (adjusted RR 1.12, 95% CI 1.04 to 1.22). Similar effects were noted for 'not working securely' in mathematical development, physical development and creative development. The effects of late preterm and early term birth were small in comparison with other risk factors.
Conclusions:
Late preterm and early term birth are associated with an increased risk of poorer educational achievement at age 5 years.
