Fetal growth restriction, defined as fetal growth below expectations, is statistically measured by a cutoff of birthweight for gestational age. Small-for-gestational-age (SGA) birth, however, is not always linked with fetal growth restriction: SGA infants may have reached their growth potential and just be small, while larger, non-SGA infants sometimes fail to reach their growth potential.
