Symphysiofundal height growth curve and growth velocity in pregnant women in a Nigerian community.

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.
