Growth Velocity and Sonographic Estimation of Birth Weight Among Low-Risk Pregnancies.

ABSTRACT: This study aimed to examine whether the addition of fetal growth velocities, based on serial scans, compared with estimated fetal weight (EFW) alone, improves the prediction accuracy of birth weight (BW).From the prospective National Institute for Child Health and Human Development Fetal Growth Studies, Singletons (2009-2013) that recruited women at low-risk for aberrant fetal growth, we included 2,397 participants with two to five ultrasounds between 15 and 41 weeks. Fetal growth velocity (V) was calculated between successive visits. Linear regression estimated the relationship between EFW and BW: non-V model, absent all growth velocities, included EFW at visit 5, interval from visit 5 to delivery, their cubic polynomials, and delivery gestational age; all-V model added all availab
