Estimating Gestational Age from Longitudinal Maternal Anthropometry During Pregnancy and Neonatal Anthropometry at Birth

The talk will present work on estimating gestational age in situations where ultrasound metrics are not available. Instead, we use repeated maternal anthropometry measures such as fundal height and cross-sectional neonatal anthropometry measures (at birth) to estimate the date of conception. We conduct a comprehensive simulation study to assess robustness of the method to model specification and illustrate this procedure using data from the National Institute of Child Health and Human Development fetal growth studies.
