1097 Trouble with the curve: is an ultrasound growth curve needed to predict SGA infants?

چکیده
Some have argued for the direct use of newborn growth curve to predict small gestational age (SGA) infants based on prenatal ultrasound estimated fetal weight (EFW). Our objective was compare Hadlock (GC) with Fenton (FC) in predicting SGA EFW. We performed a retrospective cohort study from 01/01/18 01/01/19 all ultrasounds 30+0 32+6 and 35+0 36+6 weeks single institution. Multifetal gestations demises were excluded. determined (EFW) patients using GC. The EFW, (GA), sex used calculate an expected FC percentile. Fetal restriction (FGR) defined as EFW <10th percentile GA, each parameter. actual birthweight if by WHO GCs term preterm infants, respectively. primary outcome ability GC at birth.

متن کاملLatent Growth Curve Modeling
A fundamental observation in the social and behavioral sciences is that people change over time, but not necessarily in the same way or at the same rate. For example, verbal ability increases steadily throughout the elementary school years, but it does not increase at the same rate for all students. There are individual differences in the rate and direction of change in many contexts, and these...

متن کاملLatent Growth Curve Analysis
Learning and development are ubiquitous. When new skills are acquired, when attitudes and interests develop, people change. Measuring change demands a longitudinal perspective, with multiple waves of data collected on representative people at sensibly spaced intervals. Multi-wave data is usually analyzed by individual growth modeling using a multilevel model for change (Singer & Willett, 2003)....
