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.
Background:
Advances in neonatal care have improved survival rates for infants born very preterm (VP) and/or with very low birth weight (VLBW), yet their long-term outcomes into adulthood remain understudied.
Objectives:
To assess the impact of VP/VLBW status on mortality, educational attainment, and labor market outcomes in early adulthood using data from the RECAP Preterm Project.
Methods:
We used harmonized data from 5 nationally representative cohort studies in high-income countries (Canada, Germany, the Netherlands, New Zealand, and Norway) participating in the RECAP Preterm Project. Our sample included 2493 individuals born VP/VLBW and 496 control patients born at term. We used coarsened exact matching to compare adult outcomes between infants who were VP/VLBW and those born at term and an instrumental variable approach-using maternal nulliparity-to estimate the marginal effect of gestational age within the VP/VLBW group.
Results:
Mortality before adulthood was 16.7 percentage points greater among individuals who were VP/VLBW compared with control infants born at term (95% CI 13.2-20.2). Among survivors, the likelihood of attaining less than secondary education was 4.3 percentage points greater (95% CI -0.8 to 9.4). Differences in economic activity and working hours were small and uncertain. Within the VP/VLBW group, each additional week of gestational age was associated with a 6.8 percentage point reduction in mortality (95% CI -12.7 to -1.0), with weaker associations for educational and labor market outcomes.
Conclusions:
VP/VLBW birth is associated with elevated mortality and educational disadvantage in early adulthood. These findings highlight the importance of long-term support for this population beyond neonatal survival, particularly in education and development policy.
