from Fetal Growth and Well-being
Published online by Cambridge University Press: 21 October 2019
Difficulties with the diagnosis, management and treatment of fetal growth problems start with defining which small fetus or newborn is affected by fetal growth restriction (FGR). A small for gestational age (SGA) fetus is diagnosed when its estimated fetal weight (EFW), or its components such as abdominal circumference (AC), fall below the 10th centile for the given gestation. This definition will include both healthy small fetuses and those who fail to reach their growth potential and who are considered to have FGR. There are many factors known to contribute to the reduction of fetal growth velocity, such as chromosomal anomalies, genetic syndromes and infections as well as maternal and environmental factors, including poor periconceptual diet and cigarette smoking. Other known risk factors for FGR include maternal co-morbidities, especially preexisting hypertensive disorders, the use of assisted reproductive techniques, and obstetric complications like heavy, recurrent vaginal bleeding or loss of co-twin.
