ABSTRACT

Background: Ultrasonography is a cornerstone in antenatal care for monitoring fetal growth and estimating fetal weight using biometric parameters such as abdominal circumference (AC), head circumference (HC), and femur length (FL) [1,2].

Objective: To evaluate the correlation between ultrasonographic fetal biometric measurements and neonatal birth weight.

Methods: A prospective observational study was conducted on 90 pregnant women between 20–22 weeks of gestation. Fetal biometric parameters were recorded using ultrasonography, and neonatal birth weight was measured after delivery. Statistical analysis included one-way ANOVA, Pearson correlation, and linear regression.

Results: A statistically significant increase in birth weight was observed with increasing AC, HC, and FL (p < 0.001). Strong positive correlations were found for AC (r = 0.78), HC (r = 0.74), and FL (r = 0.71).

Conclusion: Ultrasonographic fetal biometric parameters are reliable predictors of neonatal birth weight and are valuable tools in antenatal care.
