Obstetric problems concerning macrosomia were evaluated by retrospective review of 91 pregancies that resulted in the delivery of an infant weighing 4,000gm or more at the Yeungnam University Hospital during 3 1/2 years from Jun. 1983 to Oct. 1986. The results obtained were as follows. 1. Macrosomic infants weighing 4.000gm or more occured in 2.8% of the deliveries. 2. 65.9% of macrosomic infants and 53.5% of total infants were male. The ratio of male was statistically higher in the macrosomic infants than in the total infants(P<0.05). 3. The incidence of macrosomia was higher with increasing qestational age, and deliveries at 42 weeks or more gestation were more common in the macrosomic infants than in the total infants(P<0.01). 4. The incidence of macrosomia was highter with increasing parity, and stastically higher in the multipara than in the primipara(P<0.01). 5. There was no difference in the incidence of macrosomia between the mothers aged 24 or less and that of 30 or more. 6. The cesarean section rate of macrosomia(30.8%) was stastically higher than that of the total infants(15.7%)(P<0.01) 7. With the pregnacy and delivery of macrosomic infants, 22 antepartum anemia(24.2%), 10 postpartum hemorrhage(11.0%), 9 birth canal injury(10.0%), 7 prolonged second stage of labor (7.7%), 4 breech presentation, and 3 pregancy induced hypertension occured in the mothers, and 10 asphyxia(or Apgar score 6 or less), 2 shoulder dystocia, 1 intrauterine fetal death, and 1 sacrococcygeal teratoma occured in the infants.
