Fetal Macrosomia And Associated Factors at The National Hospital Center of Pikine (CHNP) Dakar/ Senegal

Introduction: Fetal macrosomia is a major risk factor for perinatal and maternal morbidity and mortality in developing countries such as Senegal. With this in mind, the objectives of our study were to describe the epidemiological, clinical, paraclinical and evolutionary characteristics of macrosomic newborns admitted to the Pikine National Hospital Center and to study the factors associated with macrosomia. Materials and methods: This was a prospective study conducted over a period of 6 months, from 1 December 2021 to 30 June 2022 at the CHN of Pikine. Results: The hospital prevalence was 4.79%. The most represented maternal age group was between 25 and 35 years. The medical-obstetric pathologies during pregnancy were dominated by gestational diabetes (46.1%). The average maternal body mass index (BMI) during pregnancy was 28.47 ± 4.7 kg/m². The majority of macrosomic babies were born at term. Macrosomia was Grade 1 in 75.65% of cases. The main complications were hypoglycaemia and obstetric trauma. Cardiac abnormalities were found in newborns of diabetic mothers. Mortality was 2.61%. Factors that were significantly associated with macrosomia were: multiple gestations, multiple pregnancies and a history of macrosomia. Conclusion and recommendations: Even if its incidence seems low compared to LBW, fetal macrosomia can lead to obstetrical and neonatal complications that can be dramatic for the mother and/or the newborn; hence the need to ensure their prevention through better monitoring of pregnancy and delivery in all pregnant women at risk.
