Objective: To evaluate the relationship between umbilical cord circumference and birth weight.
Material and Methods: 50 singleton gravidae between 32 - 42 weeks admitted in labor and delivered within 12 - 24 hours were included. Pregnancies with structural anomalies were excluded. Ultrasound measurement of umbilical cord circumference was obtained from cross sectional three vessel view of a free loop. The relationship between umbilical cord circumference, birth weight and gestational age were analyzed using correlation and regression.
Setting: Department of Obstetrics and Gynecology, Al Sadr teaching hospital.
Results: There was no significant correlation between gestational age and umbilical cord circumference in the gestational range studied. Umbilical cord circumference correlated with birth weight, (r = 0.8, P <0.001). A simple regression equation can be used to give an estimation of fetal weight.
Birth weight (gm) = C2 + 35 C (mm)
Where C is the umbilical cord circumference.
Conclusion: Umbilical cord circumference, measured by ultrasound prior to delivery may be helpful in predicting birth weight.

Key words: Umbilical cord circumference, Birth weight.
