title: [Effect of risk factors on premature labor and neonatal condition following delivery].
abstract: The influence of risk factors on the course of pregnancy in cases of preterm delivery, and on the mortality and morbidity of the premature infants, was investigated in a retrospective study. Data of 574 patients who bore children weighing under 2500 g between 1976 and 1986, and of a control group of 574 patients who gave birth during the same period to infants weighing over 2500 g were statistically analyzed. In the preterm population there was a significantly higher incidence of previous treatment for sterility, repeated miscarriages and prior preterm births. Smoking doubles the risk of preterm birth. Pathologic Apgar scores and acidosis morbidity were found significantly more frequently among mothers who smoked. The mortality and morbidity of the neonate depend on its birthweight and the duration of pregnancy. A considerably better prognosis may be expected if the infant weighs over 2000 g and is born after the 32nd week of gestation.
