title: High malformation rates and decreased mortality in infants of diabetic mothers managed after the first trimester of pregnancy (1956-1978).
abstract: Over a period of 23 years we accumulated data on 182 pregnant juvenile diabetic subjects during pregnancy, labor, and delivery. Diabetic subjects were evaluated generally after the first trimester of pregnancy. Data examined included diabetic class, maternal complications of pregnancy, and infant morbidity and mortality. Data were analyzed in two periods-before and after 1970. In the second period, maternal polyhydramnios and acidosis rates improved, neonatal problems of homeostasis did not change significantly, and combined fetal and neonatal losses fell from 34.7% to 16.4%. The neonatal malformation rate, however, increased from 1.4% to 16.8% and was not influenced by maternal age or diabetic class.
