The fetal abdominal circumference (FAC) and biparietal diameter to transverse abdominal diameter ratio (BPD/TAD) were measured by ultrasound in 219 normal pregnant Nigerian women from 20 weeks until term using the cross-sectional method. There was a progressive linear growth of the FAC and a consistent standard deviation throughout the study period. When compared to caucasian growth curves, the curve shapes were identical but the FAC values were consistently less for each week of gestation in our Nigerian sample. The BPD/TAD ratio showed a progressive fall from 20 weeks until term similar to that previously noted for fetal head circumference to abdominal circumference ratio, indicating that this parameter may also be useful for predicting abnormal fetal growth.
采用横断面研究方法，对219名尼日利亚正常孕妇从孕20周直至足月进行超声检查，测量胎儿腹围（FAC）及双顶径与腹横径比值（BPD/TAD）。整个研究期间，FAC呈渐进性线性增长且标准差一致。与白种人的生长曲线相比，曲线形状相同，但在尼日利亚样本中，各孕周的FAC值始终较低。BPD/TAD比值从孕20周直至足月呈逐渐下降趋势，类似于之前所观察到的胎儿头围与腹围比值，表明该参数也可能有助于预测胎儿生长异常。
