Insights
Congenital anomalies significantly impact the growth and neurodevelopment of very low birth weight infants (VLBWIs), leading to persistent growth restriction and motor delays. Early interventions are crucial for improving outcomes.
Area of Science:
- Neonatal research
- Pediatric developmental science
- Congenital anomaly studies
Background:
- Very low birth weight infants (VLBWIs) face risks of growth restriction and neurodevelopmental issues.
- Congenital anomalies exacerbate these risks, but long-term effects require further investigation.
Purpose of the Study:
- To investigate the long-term impact of congenital anomalies on the growth and neurodevelopment of VLBWIs.
Main Methods:
- Prospective cohort study using Korean Neonatal Network data (2013-2017).
- Matched VLBWIs with and without congenital anomalies at 18-24 months and 3 years corrected age.
- Assessed growth via WHO standards and neurodevelopment using Bayley Scales and KDST; logistic regression identified risk factors.
Main Results:
- VLBWIs with congenital anomalies showed significantly lower weight, height, and head circumference z-scores.
- Persistent growth restriction and increased prevalence of neurodevelopmental delays, especially motor deficits, were observed.
- Multiple congenital anomalies correlated with the highest risk of severe growth restriction and developmental impairment.
Conclusions:
- Congenital anomalies present substantial challenges to VLBWI growth and neurodevelopment.
- Individualized interventions, structured follow-up, and multidisciplinary care are vital for optimizing long-term outcomes.
Background:
Very low birth weight infants (VLBWIs) are vulnerable to growth restrictions and neurodevelopmental impairments. Congenital anomalies further complicate these risks; however, their long-term effects remain unclear. This study examined the impact of congenital anomalies on the growth and neurodevelopment of VLBWIs.
Methods:
This prospective cohort study analyzed data from the Korean Neonatal Network (2013-2017). A total of 172 VLBWIs with congenital anomalies were matched by gestational age to 516 without anomalies at 18-24 months corrected age, and 136 were matched to 408 at 3 years of age. Growth was assessed using WHO standards, and neurodevelopment was evaluated using the Bayley Scales of Infant Development (II/III) and Korean Developmental Screening Test. Logistic regression analyses were used to identify factors associated with adverse outcomes, with statistical significance set at P < 0.05.
Results:
VLBWIs with congenital anomalies had significantly lower weight, height, and head circumference z-scores at both time points. Growth restriction persisted, and neurodevelopmental delays, particularly in motor function, were more prevalent. Infants with multiple congenital anomalies had the highest risk of severe growth restriction and developmental impairment.
Conclusion:
Congenital anomalies pose significant challenges to the growth and neurodevelopment of VLBWIs. Early and individualized interventions, structured neurodevelopmental follow-up, and multidisciplinary care are essential for improving long-term outcomes.
