Abstract
In this study of the umbilical cord lengths of 602 Nigerian infants delivered at term, the mean, median and modal measurements were 57.48, 57.71 and 68.00 cm, respectively (range = 20–100 cm). There was a significant positive correlation between cord length and fetal weight (r = 0.2177, p < 0.001) and also between cord length and placental weight (r = 0.2504, p < 0.001). Other fetal and maternal variables studied did not correlate with cord length. Further investigations of the factors responsible for the growth of the umbilical vessels are needed.
