A prospective survey of symphysiofundal height (SFH) was undertaken in 202 Nigerian pregnant women in Uromi, Edo State, Nigeria, with the objective of constructing an SFH growth chart for the pregnant population in the community. A customised gravidogram and a growth velocity curve were also constructed and compared with those derived in other regions of the world. The average SFH growth rate between 20 and 40 weeks was 0.8 cm/week. The gradient of the curve was not constant and the SFH growth rate changed with the progression of pregnancy. While the average SFH growth rate between 20 and 36 weeks was 0.9 cm/week, from 36 to 40 weeks there was a marked deceleration to 0.3 cm/week. The average deviation from the mean SFH was 1.96 cm. It is recommended that regional customised gravidograms be derived for different pregnant populations which should be reviewed periodically. With this, routine SFH assessments can help in early detection of fetal growth rate anomalies based on an understanding of the peculiarities of fetal growth patterns in each community.
