Abstract :

Background: Birth weight is the most important parameter to determine the neonatal survival rate. Methods: This research used cross sectional study that compared the level of accuracy between Risanto, Dare and Johnson Toshach formulas in determining estimated fetal weight (EFW). Results: The accuracy analysis in predicting EFW using the ROC curve for Johnson Toshach�s formula was p = 0.036, the value of Area Under Curve (AUC) was 73.9% (IK = 95%), sensitivity of 76.1%, specificity of 75.0%. For the Risanto formula was p = 0.02, AUC value 84.5% (IK =95%), sensitivity of 81.5%, specificity of 87.5%. For Dare formula was p = 0.02, the AUC value was 85.7% (IK =95%), sensitivity of 92.4%, specificity of 87.5%. Conclusion: The Dare formula was the most accurate in determining EFW compared to the Risanto formula and Johnson Toshach formula.
