Exploring Maternal Nutrition and Its Impact on Fetal Growth Patterns in Urban Communities: A Study on Pregnant Women in Ojo, Lagos State, Nigeria

Accurate estimation of fetal weight is crucial for prenatal care and decision-making. This study aimed to develop a fetal anthropometric model using ultrasound measurements to estimate fetal weight between 20-40 weeks of gestation in Ojo, Lagos State. A longitudinal study of 300 pregnant women was conducted, with obstetric ultrasoundscans images. Fetal biometric parameters (biparietal diameter and head circumference) were measured and correlated to estimate fetal weight using Hadlock’s formula. Regression analysis was used to develop a predictive model for estimating fetal weight. From the results,there was a negative correlation between fetal biometric parameters and estimated fetal weight (R2 = 0.113, p < 0.001). This study provides a reliable and accurate method for estimating fetal weight in the Nigerian population, enhancing prenatal care and obstetric decision-making.
