The fetal biparietal diameter (BPD) was measured on 1104 occasions in 552 Nigerian women during normal pregnancy, and the range of BPD values for each week of pregnancy between 12 and 40 weeks was determined. Growth of the BPD in our population showed an asymptotic curve like that of Europeans but our values were slightly higher. The mean weekly increase in the BPD between 13 and 30 weeks gestation was 4.9 mm/week, between 30 and 36 weeks, 3.3 mm/week and between 37 and 40 weeks, 1.7 mm/week. But there was no significant difference between the BPD measurements of Europeans and Nigerian fetuses except towards term.
在552名尼日利亚正常妊娠女性中，对其胎儿双顶径（BPD）进行了1104次测量，并确定了妊娠12至40周期间每周BPD值的范围。我国人群中BPD的增长呈现出与欧洲人相似的渐近曲线，但我们的值略高。妊娠13至30周期间BPD的平均每周增加量为4.9毫米/周，30至36周期间为3.3毫米/周，37至40周期间为1.7毫米/周。但除了接近足月时，欧洲胎儿和尼日利亚胎儿的BPD测量值之间没有显著差异。
