title: Normal growth of the fetal biparietal diameter in an African population.
abstract: The fetal biparietal diameter (BPD) was measured by ultrasound during normal pregnancy in 558 Nigerian women. The range of BPD values for each week of pregnancy from 12 weeks until term (713 measurements) was computed from cross-sectional data. The data were used to illustrate the variation in weekly growth rate according to fetal maturity and head size. The results revealed a curve similar to those reported from Caucasian populations but with much less flexion in the later weeks of pregnancy. The BPD values per week were also less in this study group. The reasons for these differences are discussed.
