Maternal BMI and Diagnostic Accuracy of Using Estimated Fetal Growth to Predict Abnormal Birthweight: Results from NICHD Fetal Growth Studies.

ABSTRACT: Background/Objectives: The objective of this study was to assess the diagnostic accuracy of sonographic estimated fetal weight (EFW) in predicting small (SGA)- or large-for-gestational-age (LGA) birthweight and examine whether the accuracy is associated with maternal body mass index (BMI). Methods: The participants of NICHD Fetal Growth Studies with complete data on maternal BMI (10-13.9 weeks), EFW within 14 days of delivery (18-41.3 weeks), and birthweight were included in this study. Participants were categorized as normal (BMI 18.5-24.9 kg/m²) or overweight/obese (BMI > 24.9 to 44.9 kg/m²). EFW accuracy was evaluated using area under the Receiver Operating Characteristic curves (AUCs) for SGA and LGA classification, and EFW error was analyzed across
