Abstract
Background: The Sonographic cross sectional study was to determine the curve for umbilical cord diameter with respect to fetal age in primi and multi gravida separately. Methods: 100 uneventful pregnancies of second and third trimester were studied. SPSS, v17, IBM, Chicago, were used for statistical analysis and polynomial regression equations were calculated. Results: The regression equation of umbilical cord diameter to Gestational Age : y=-0.018x2+1.290x-9.418(R2=0.585) in primigravida . For multigravida cord diameter to Gestational Age : -6.020 + 0.990 x – 0.012 x2 (R2 0.613) , where x is fetal age in weeks , y is cord diameter in milimetres. Conclusion: The diameter increased significantly with fetal age upto 32 weeks, thereafter a plateau was seen
