Correlates of human umbilical cord length.
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 less than 0.001) and also between cord length and placental weight (r = 0.2504, p less than 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.
