Abstract
Objectives: To compare the accuracy of Johnson's and Risanto's for¬mulas in determining estimated fetal weight based on maternal fun-dal height (FH).

Methods: This was a cross sectional study, consisting of 655 preg¬nant women from Dr. Sardjito Hospital and affiliated hospital sat 37- 42 weeks of gestation. Fundal height was measured from the sym¬phisis to the top of uterine fundus, using inverted unelastic flexible tape. EFW based on Johnson's and Risanto's formulas were corn-pared with the actualbirth weight. Wilcox on analysis was used for statistical analysis.
Results: Mean EFW of Johnson's formula was 3136 ± 392.2 grams and EFW of Risanto's formula was 3056 ± 322.5 grams and mean ac¬tual birth weight was 3021 ± 341.1 grams. The mean difference be¬tween EFW of Johnson's formula and the actual birth weight was 156.1 ± 107.3 grams, and mean difference between EFW of Risanto's formula and the actual birth weight was 100.8 ± 86.1 grams. Those two differences was statistically significant (p=0.001).

Conclusion: This study showed that Risanto's formula was more ac¬curate than Johnson's in predicting birth weight based on the mater¬nal's fundal height.
