Clinical aspects of pregnant diabetics have recently changed in comparison with those of 10 years ago. We analyzed the clinical aspects of 89 pregnant diabetics, 109 deliveries and 110 children born from February 1964 to March 1982.
The incidence of deliveries by diabetics was 1.23%, and it has increased recently. The mean age of onset of the diabetes diabetes was 23.2 yr. The mean duration of diabetes was 5.9 yr. The number of pregnant diabetics who had diabetes before the age of 15 and whose duration was over 10 yr has increased.
Of 89 pregnant diabetics, 26 had Type I diabetes, and 63 had Type II. Since 1975 the incidence of Type I pregnant diabetics has increased. Eighty-one pregnant diabetics were treated with insulin. Fifty-three pregnant diabetics had retinopathy and half of them showed deterioration during pregnancy. Among pregnancy complications the commonest one was asymptomatic bacteriuria. The mean gestational age of delivery was 39.3 weeks. Half of the babies were delivered by Caesarean section. The perinatal mortality was 5.6%. No intrauterine deaths have been in our patients recently; however deaths due to major congenital malformation have increased. After 37 weeks of gestation the mean weight of neonates at birth was 3438 g. The percentage of infants who were heavy for their gestational age was 33.6%, Eighteen children had congenital malformations. The commonest complication among the newborns was hypoglycemia.
