The relationship between fetal biparietal diameter measured by echography and menstrual age for blacks was studied. Predicted values and their confidence limits are presented in tables and graphs. The biparietal diameter was significantly smaller from 28 weeks than American and European studies, demonstrating that a composite graph was not applicable to the Zulus. The echographic results were checked at term by external cephalometry. Occipitofrontal circumference and birth weights for newborns were found similar to other studies. The smaller BPD in late pregnancy could be explained by the head's shape. The new charts are valuable in assessing fetal growth in African blacks.
研究了通过超声检查测量的黑人胎儿双顶径与月经龄之间的关系。预测值及其置信限以表格和图表形式呈现。从28周起,双顶径明显小于美国和欧洲的研究结果,表明综合图表不适用于祖鲁人。超声检查结果在足月时通过外部头围测量进行核对。发现新生儿的枕额周长和出生体重与其他研究相似。妊娠晚期双顶径较小可能由头部形状来解释。新图表在评估非洲黑人胎儿生长情况方面很有价值。
