SFH measurement first used to estimate the
gestational age. In 1977, Westin B(2) found that the SFH
could be used as a tool to follow fetal growth. One year
later, Woo et al(3) demonstrated that SFH and abdominal
girth could be used to predict birthweight. In 1995,
Walraven GE et al(4) found that SFH could be used to
predict the size of the infant. In Thailand, Pongrojpaw
et al(5) and Pongsawatkul K(6,7) investigated the role of
symphysis fundal height of as a prediction for fetal
birthweight.
