Insights

Preterm birth is linked to lower adult intellectual performance. Poor postnatal growth, indicated by short stature or high BMI, further increases this risk in preterm-born males.

Area of Science:

  • Developmental Pediatrics
  • Neuroscience
  • Public Health

Background:

  • Preterm birth is a significant global health concern.
  • Understanding long-term cognitive outcomes of preterm birth is crucial.
  • The role of postnatal development in modulating these outcomes requires further investigation.

Purpose of the Study:

  • To investigate the association between preterm birth and adult intellectual performance.
  • To examine the specific influence of postnatal growth factors on this association.

Main Methods:

  • Population-based cohort study of 272,046 males born 1973-1978.
  • Utilized Swedish Medical Birth Register and Swedish Conscript Register data.
  • Employed multiple logistic regression analysis to assess relationships.

Main Results:

  • Males born preterm demonstrated lower intellectual performance at conscription compared to term-born peers.
  • Short adult stature in preterm-born males amplified the risk of low intellectual performance.
  • High adult body mass index (BMI) in preterm-born males was also associated with increased risk of subnormal performance.

Conclusions:

  • Preterm birth is associated with poorer intellectual performance in adulthood.
  • Suboptimal postnatal growth (short stature, high BMI) exacerbates cognitive deficits in preterm-born individuals.
  • Suggests shared underlying mechanisms influencing both physical growth and cognitive development.

Nature and Nurture01:10

Nature and Nurture

Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience, such as differences...
Biological Influences on Intelligence01:30

Biological Influences on Intelligence

Intelligence is often thought to be linked to brain size, but the relationship is more complex than that. While brain size does correlate modestly with some abilities, like verbal skills, the connection is weaker for others, such as spatial reasoning. Other factors, like brain structure, also play crucial roles. For instance, despite Einstein's smaller-than-average brain, his parietal cortex, which is involved in spatial reasoning, was 15% wider, suggesting that neural density might matter more...
Intellectual Disability01:29

Intellectual Disability

Intellectual disability (ID) is a neurodevelopmental condition characterized by deficits in intellectual and adaptive functioning that manifest during the developmental period. This condition encompasses challenges in reasoning, memory, problem-solving, and learning, accompanied by impairments in everyday life skills, such as communication, self-care, and social interactions. Intellectual disability affects approximately 1% of the population in the United States, impacting an estimated 5...
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...
Signs of Puberty01:27

Signs of Puberty

Puberty is a critical phase, typically beginning between the ages of 8 and 13 in girls and 9 and 14 in boys, though timing can vary based on genetics, environmental factors, and overall health. This period is characterized by the development of secondary sexual characteristics and the attainment of reproductive potential. Endocrine changes underpin puberty, with hormonal surges of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) instigated by Gonadotropin-Releasing Hormone (GnRH)...
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.
