Insights

Infants born very preterm (VP) or with very low birth weight (VLBW) face higher mortality and educational disadvantages in adulthood. Long-term support is crucial for their development beyond neonatal survival.

Area of Science:

  • Neonatal research
  • Developmental pediatrics
  • Public health

Background:

  • Neonatal care advances improve survival for very preterm (VP) and very low birth weight (VLBW) infants.
  • Long-term outcomes into adulthood for VP/VLBW survivors are understudied.

Purpose of the Study:

  • To assess the impact of VP/VLBW status on adult mortality, education, and labor market outcomes.
  • Utilize data from the RECAP Preterm Project for comprehensive analysis.

Main Methods:

  • Harmonized data from 5 national cohort studies in high-income countries.
  • Compared 2493 VP/VLBW individuals with 496 term-born controls using coarsened exact matching.
  • Employed instrumental variable approach (maternal nulliparity) to estimate gestational age effects.

Main Results:

  • VP/VLBW individuals had 16.7% higher mortality before adulthood compared to term controls.
  • Survivors showed a 4.3% greater likelihood of less than secondary education.
  • Each additional week of gestational age reduced mortality by 6.8% within the VP/VLBW group.

Conclusions:

  • VP/VLBW birth is linked to increased adult mortality and educational disadvantage.
  • Emphasizes the need for continued support in education and development policy for VP/VLBW individuals.
  • Highlights the importance of long-term follow-up beyond neonatal intensive care.

Theory of Romantic Attachment in Adulthood

Attachment is a long-standing connection or bond with others. While Attachment Theory was conceived in developmental psychology to describe infant-caregiver bonding, it's been extended into adulthood to include romantic relationships.

The Evidence for Evolution

Genetic variations accumulating within populations over generations give rise to biological evolution. Evolutionary changes can result in the formation of novel varieties and entire new species. These changes are responsible for the diverse forms of life inhabiting the planet. The evidence for evolution suggests that all living organisms descended from common ancestors.
