Six hundred and sixty-one consecutive umbilical cords of babies at term in an African obstetric population were studied. The mean cord length was 58.4 +/- 12.02 cm. The pattern of frequency distribution of cord length in this study conforms to previous findings from other racial groups, establishing the fact that cord length and its variability are not racially determined. There is a significant correlation between the cord length and weights of the fetus and placenta but not with the mother's parity.
对非洲产科人群中661例足月婴儿的脐带进行了连续研究。脐带平均长度为58.4±12.02厘米。本研究中脐带长度的频率分布模式与其他种族群体先前的研究结果一致，证实了脐带长度及其变异性并非由种族决定这一事实。脐带长度与胎儿及胎盘重量之间存在显著相关性，但与母亲的产次无关。
