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.

Information Processing Approach01:30

Information Processing Approach

The information-processing theory of cognitive development centers on fundamental mental processes, including attention, memory, and problem-solving skills. Researchers in this field examine how cognitive abilities, such as working memory, evolve and influence children's overall development. Studies indicate that children with stronger working memory tend to excel in reading comprehension, math, and problem-solving compared to peers with less efficient memory skills. Low working memory is also...
Environmental Influences on Intelligence01:29

Environmental Influences on Intelligence

Despite the strong genetic influence on traits like intelligence, environmental factors significantly shape outcomes. For example, while over 90% of height variation is due to genetic differences, environmental factors such as nutrition also have a notable impact. Similarly, for intelligence, changes in a child's surroundings can significantly alter their IQ. Research shows that enriched environments boost children's academic success and help them develop key cognitive skills. Children from...
Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings.
Regression Toward the Mean01:52

Regression Toward the Mean

Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when researchers try to extrapolate results...
Conduct Disorder01:28

Conduct Disorder

Conduct disorder is a complex mental health diagnosis characterized by a repetitive and persistent pattern of behavior that violates societal norms, the rights of others, or age-appropriate rules. The diagnostic criteria for conduct disorder require the presence of at least three problematic behaviors within the past 12 months, with at least one occurring in the past six months. These behaviors are grouped into four categories: aggression toward people and animals; destruction of property;...
Socioemotional Development during Infancy01:30

Socioemotional Development during Infancy

Socio-emotional development in infancy is primarily shaped by early emotional responses and social connections, with temperament playing a central role. Temperament refers to the consistent patterns in an individual's emotional and behavioral responses, observable even in infancy. By examining temperament, researchers can better understand an infant's unique ways of interacting with the world, influencing subsequent personality and socio-emotional growth.
