Summary
Infants with intrauterine growth retardation (IUGR) show initial catch-up growth, but many remain small. Preterm infants with IUGR face higher mortality and persistent growth deficits by 18 months.
Area of Science:
- Pediatrics
- Neonatology
- Growth and Development
Background:
- Intrauterine growth retardation (IUGR) affects fetal development.
- Understanding long-term growth patterns in IUGR infants is crucial.
Purpose of the Study:
- To analyze the growth trajectories of infants with significant IUGR during the first two years of life.
- To compare growth outcomes between term and preterm infants with IUGR.
Main Methods:
- Longitudinal study of 158 infants with IUGR.
- Data collection on weight and height for the first 24 months.
- Analysis of growth acceleration, catch-up potential, and percentile attainment.
Main Results:
- Term IUGR infants showed early weight and linear catch-up growth, but 29% remained below the 5th percentile by 2 years.
- Preterm IUGR infants had 18% mortality, with 44% below the 5th percentile for weight at 18 months post-term.
- Catch-up growth potential in preterm infants extended to 9 months post-term.
Conclusions:
- While catch-up growth occurs, a significant proportion of IUGR infants, especially preterm, experience persistent growth deficits.
- Neonatal factors and gestational age influence long-term growth outcomes in IUGR populations.
