Summary
Biologic variability in fetal size emerges early in pregnancy, with distinct growth patterns identifiable by 12 weeks gestational age. These early anthropometric differences persist throughout pregnancy, suggesting early genetic influence on fetal growth.
Area of Science:
- Obstetrics and Gynecology
- Fetal Development
- Neonatal Research
Context:
- Biologic variability in fetal size increases with gestational age.
- Early fetal growth patterns and influencing factors remain debated.
- Transversal studies may underestimate early fetal growth variability.
Purpose:
- To evaluate embryo-fetal growth differentiation using a longitudinal study.
- To correlate early fetal growth with neonatal anthropometric measurements.
- To identify the timing of fetal growth differentiation.
Summary:
- A longitudinal study analyzed 238 neonates from low-risk pregnancies.
- Fetal growth velocity curves showed differences by 12 weeks gestational age.
- Anthropometric differences observed early persist until term, indicating early genetic potential expression.
Impact:
- Demonstrates that anthropometric differences are present by the first trimester.
- Suggests a very early expression of genetic potential for individual fetal growth.
- Highlights the importance of early fetal assessment in understanding growth trajectories.
