Insights
Very preterm children show poorer cognitive and behavioral outcomes compared to term-born peers, even with similar high parental education. The number of highly educated parents also influences child outcomes.
Area of Science:
- Pediatric developmental neuroscience
- Child psychology
- Educational psychology
Background:
- Children born very preterm often exhibit poorer cognitive, academic, and behavioral outcomes than term-born peers.
- Previous findings may be confounded by lower parental education levels in very preterm populations.
- Studies controlling for parental education are crucial to determine the true impact of very preterm birth.
Purpose of the Study:
- To compare cognitive, academic, and behavioral functioning in very preterm and term-born children from highly educated families.
- To investigate if outcomes differ based on whether one or both parents are highly educated.
Main Methods:
- Cross-sectional study design with a term-born comparison group.
- Inclusion of 113 very preterm and 38 term-born children aged 8-12 years with highly educated parents.
- Assessment of cognitive (IQ), academic (reading, arithmetic), and behavioral functioning (attention, executive function, hyperactivity, emotional, conduct, peer problems).
Main Results:
- Very preterm children demonstrated significantly lower cognitive functioning (10 IQ points difference) and behavioral functioning compared to term-born peers.
- No significant differences were observed in academic functioning between the groups.
- Children with one highly educated parent performed worse on most measures than those with two highly educated parents.
Conclusions:
- Accurate assessment of very preterm children's outcomes requires comparison with term-born peers of similar high socioeconomic status (parental education).
- The number of highly educated parents is a significant factor influencing child outcomes.
- Parental education level is a critical covariate in studies of preterm birth effects.
Background:
Compared to their term-born peers, children born very preterm are at risk for poorer cognitive, academic and behavioral outcomes, however this finding may have been confounded by lower parental education level in the very preterm children. Studies that compare very preterm and term-born children with comparable (high) parental education level are needed to assess the true effect of very preterm birth on outcomes.
Aims:
To compare cognitive, academic and behavioral functioning in very preterm and term-born children of highly educated parents. To examine whether outcomes differ for children of whom one or both parents are highly educated.
Study Design:
Cross-sectional study with a term-born comparison group.
Subjects:
113 very preterm children and 38 term-born children aged 8-12 years old, with highly educated parents.
Measures:
Cognitive functioning (Intelligence Quotient), academic functioning (arithmetic facts and reading) and parent and teacher rated behavioral functioning (attention, executive function, hyperactivity, and emotional, conduct and peer problems). Parental education was considered high when children had two highly educated parents or one highly- and one middle educated parent.
Results:
Very preterm children had significantly poorer cognitive (difference of 10 IQ points) and behavioral functioning than their term-born peers, but did not differ on academic functioning. Children with one highly educated parent performed poorer than children with two highly educated parents on most outcome measures.
Conclusions:
Performance of very preterm children should be compared to term-born peers with parents having comparable educational levels for accurate assessment of outcomes. The number of highly educated parents also impacts outcomes.

Parenting Styles
Authoritarian Parenting
This style is strict and controlling, with little room for open dialogue. Authoritarian parents demand obedience and often enforce rules with minimal warmth. Children raised this way may lack social skills and initiative, usually comparing themselves to others unfavorably.
