Insights
Infants with Down syndrome exhibit reduced prenatal growth in length, weight, and head circumference compared to normal newborns. However, their weight-for-length measurements suggest overweight conditions may develop postnatally.
Area of Science:
- Pediatrics
- Genetics
- Neonatalogy
Background:
- Down syndrome is associated with various health complications, including growth abnormalities.
- Accurate growth charts are crucial for monitoring infant development.
Purpose of the Study:
- To construct percentile charts for key neonatal anthropometric variables in infants with Down syndrome.
- To compare growth patterns between infants with Down syndrome and a normal control group.
Main Methods:
- Utilized data from 688 infants with Down syndrome and 6,890 controls from Italian congenital malformation registers.
- Constructed percentile charts for neonatal length, weight, head circumference, and weight/length squared.
Main Results:
- All growth parameters (length, weight, head circumference) were lower in Down syndrome infants compared to controls across all percentiles.
- Weight/length squared percentiles were an exception, indicating different growth trajectories.
Conclusions:
- Neonatal growth is significantly reduced prenatally in infants with Down syndrome.
- Postnatal development may lead to overweight conditions in Down syndrome infants, warranting further investigation.
Abstract:
Percentile charts of neonatal length, weight, head circumference, and weight/length squared have been constructed using data based on 688 consecutive newborn infants with Down Syndrome and 6,890 normal newborn infants (control group) registered in the congenital malformation registers of North-East Italy and the Emilia-Romagna Region. All percentiles of growth variables are lower in Down syndrome than in the control infants, except for the weight/length2 percentiles, suggesting that growth in Down syndrome is prenatally reduced; overweight begins after birth.
