Summary
This study presents birth size data for 507 healthy Iranian neonates. Maternal factors like education and pre-pregnancy weight significantly influenced infant size at birth.
Area of Science:
- Pediatrics
- Neonatal Health
- Anthropometry
Background:
- Establishing normative data for neonatal anthropometry is crucial for assessing infant growth and health.
- Regional variations in birth size necessitate localized studies.
Purpose of the Study:
- To present anthropometric measurements of healthy singleton neonates born in Shiraz, Iran.
- To identify factors influencing birth size in this population.
- To analyze correlations between different anthropometric parameters.
Main Methods:
- A random sample of 507 healthy singleton neonates (244 boys, 263 girls) was studied.
- Measurements included supine length, weight, head circumference, chest circumference, and mid-upper arm circumference.
- Statistical analysis was performed to determine means, standard deviations, sex differences, and correlations.
Main Results:
- Significant sex differences were observed in length, weight, head circumference, and mid-upper arm circumference (p < 0.05).
- Maternal education, pre-conception weight, and family social class were significant predictors of birth size.
- Birth order and paternal education did not show significant effects.
Conclusions:
- The study provides valuable reference data for neonatal anthropometry in the urban Iranian population.
- Maternal characteristics play a significant role in determining infant birth size.
- Strong correlations exist between various anthropometric measurements at birth.
