[Newborn infant with macrosomia: etiologic factors and perinatal complications]

A retrospective study conducted between january 1st and december 31st 1993 allowed for the identification and comparison of 100 cases of new born with macrosomia accounting for 1.34% of birth. Males constitute the majority of those cases (60%) and the average weight found is 4212 g. Foetal complications are in the main made of lesions of the brachial plexus (9%). Hypoglycemia is found in 4% of cases. These complications are more frequent in forceps assisted deliveries or cesareans (P < 0.05). Obesity (20%), Fat child related past history (15%), Maternal diabetes (5%) are the most common risk factors. We therefore advocate a more effective prevention of foeto-pelvic disproportions through a close supervision of pregnancy among women at risk.
