A case-control study was conducted to recognize some factors associated with macrosomia. The cases were 170 neonates with 4 000 g and over, whereas the controls were 260 newborn infants with a weight that ranged between 3 000 and 3 999 g. A group of maternal risk factors, obstetric history, related to delivery and to the newborn infant were evaluated. The relative risk of each factor for associating with macrosomy was estimated by the cross product ratio (OR). The statistical significance was evaluated by the confidence interval of 95 % (CI-95 %) and by the Chi square test (X2) or the Fisher test according to each case. Maternal age over 30 (OR=4), gestational age over 42 weeks (OR=5.8), maternal height over 1.70 cm (R=6.6), history of previous macrosomic children (OR=5.7), family diabetes (OR=3.6) and the male sex (OR=2.8) were associated with macrosomia. No increase was observed in the risk of cesarean section, or low Apgar score.
