Background: Fetal macrosomia is a very prevalent pathology worldwide, it is associated with multiple comorbidities. In order to predict this pathology, the clinical method is calculated using the Johnson-Toshach method; the other is through ultrasound and the most used formula is Hadlock IV. Objective: To determine if the fetal weight calculated by the Johnson and Toshach method is more effective for neonatal macrosomia than the fetal weight by formula IV of Hadlock in the Department of Obstetrics and Gynecology at the Antonio Lorena Hospital in Cusco in 2018. Method: It is a retrospective observational case and control analytical study. The population consisted of 375 full-term pregnant women, with a single fetus in cephalic presentation who met the inclusion and exclusion criteria, 125 cases and 375 controls. The clinical history data that were later placed on the data collection form were taken. The ROC curve was used for the comparison of methods. Results: The prevalence of fetal macrosomia was 4.4%, being for the Johnson-Toshach method a sensitivity of 28.0%, specificity of 60.8%, VPP of 26.3%, NPV of 72.0%; meanwhile, by ultrasound a sensitivity of 32.0%, specificity of 58.0%, PPV of 27.6%, NPV of 63.0%, for the fetal weight according to the Hadlock IV formula. The ROC curve found an area under the curve for the Johnson-Toshach method of 0.648 IC 95% [0.592-0.704] (p = 0.003); while for the fetal weighted by ultrasound 0.713 95% CI [0.660-0.767] (p = 0.000). Among other results, it was found that 58.4% were male neonates OR = 5,768 95% CI = 2,967-11,213 P = 0,000, according to maternal age P = 0,549, 54.9% were between 20 - 30 years. Maternal size IC95% = 2,967-11,213 P = 0.496, 41.9% measured between 1.60-1.69 cm. With respect to weight 95% CI = 0.967-9.213 P = 0.559, 52.5% have normal weight and 54.4% have a weight gain between 12-16 kg OR = 1.26 IC 95% = 1.02 1.56 P = 0.693. It was determined that 5.3% have gestational DM OR = 4.82 IC95% = 1.54-15.10 P = 0.000, 52.3% are cohabitant, 48.8% have complete secondary education, 50.4% have normal prenatal checks. Regarding parity, 48.8% of cases are primitive, unlike controls, 56.4% are multigesta. Conclusion: None of the two methods to predict fetal macrosomia were conclusive since they have a low sensitivity, however, the ultrasound according to the Hadlock IV formula is slightly above the clinical method
