COMPARATIVE ACCURACY OF SONOGRAPHIC AND CLINICAL METHODS FOR ESTIMATING FETAL WEIGHT AT TERM IN A TERTIARY NIGERIAN HOSPITAL
Main Article Content
Abstract
Background: Background: Accurate estimation of fetal weight at term is critical in obstetric decision-making and preventing feto-maternal complications.
Objective: To compare the accuracy of clinical (Dare’s formula) and sonographic (Hadlock-4) methods with actual birth weight in term pregnancies.
Methods: In a prospective cross-sectional study, 60 women with singleton term pregnancies were evaluated. Fetal weight was estimated clinically and sonographically within 0–7 days before delivery. Estimates were compared to actual birth weight using paired t-tests and correlation analysis.
Results: Mean actual birth weight was 3240.83 ± 483.85 g. Sonographic estimates had a mean absolute percentage error (MAPE) of 7.97% ± 6.28 and predicted 75% of weights within ±10% of actual birth weight. Clinical estimates had a MAPE of 17.02% ± 13.97 with 36.67% within ±10%. Sonographic estimates showed stronger correlation (r = 0.711; p < 0.001) than clinical estimates (r = 0.531; p < 0.001).
Conclusion: The sonographic method was significantly more accurate in predicting fetal weight and should be preferred in clinical settings.
