Very low birthweight infants: a follow-up study.

H P Mercer, P A Lancaster, T Weiner

    The Medical Journal of Australia
    |December 16, 1978
    PubMed
    Summary

    This study followed infants born weighing 1500g or less. Fifteen percent of examined survivors had developmental delays or physical handicaps, with small-for-gestational-age infants showing poorer growth outcomes.

    Area of Science:

    • Neonatalogy
    • Pediatric Medicine
    • Developmental Pediatrics

    Background:

    • Infants weighing 1500 grams or less at birth represent a vulnerable population requiring long-term outcome assessment.
    • Understanding the long-term health and developmental trajectories of these infants is crucial for clinical practice and parental guidance.

    Purpose of the Study:

    • To determine the outcome of neonatal survivors weighing 1500 g or less at birth.
    • To identify the prevalence of physical handicaps and developmental delays in this cohort.
    • To compare growth patterns between small-for-gestational-age and appropriate-for-gestational-age infants.

    Main Methods:

    • Retrospective cohort study of infants born between 1971-1975 at the Royal Hospital for Women.
    • Follow-up assessment of neonatal survivors weighing 1500 g or less.
    • Clinical examination to identify major and minor physical handicaps and developmental delay.

    Main Results:

    • Of 104 neonatal survivors, 88 were examined.
    • Abnormalities were identified in 15% of examined children, including major physical handicaps (3%), minor handicaps (11%), and developmental delay (8%).
    • Infants identified as small for gestational age exhibited a higher tendency for below-10th percentile height or weight at follow-up compared to appropriate-for-gestational-age infants.

    Conclusions:

    • A significant proportion of low birth weight infants (≤1500g) experience long-term handicaps or developmental delays.
    • Early identification and intervention are essential for improving outcomes in this high-risk group.
    • Gestational age-adjusted growth is an important factor influencing long-term development in very low birth weight infants.
