title: [Causes of premature labor in pregnancy complicated by diabetes depend on diabetes progression].
abstract: The aim of this study was to demonstrate what factors influence preterm termination of pregnancy complicated by diabetes, in dependence of diabetes progression. The following factors have been analysed: rate and causes of preterm labours according to White classification, mean duration of pregnancy, mode of delivery, birth weight, Apgar score and diabetes control in the preterm delivered women with different progression of disease. As a result we observed, that in G/A and G/B classes and in short lasting class B, the most common cause of preterm labour was spontaneous delivery and prematurity rate was low, oscillated between 1.7 and 15.8 percent. In those classes we also observed that diabetes control was very good or adequate. In D, R, F, and RF classes the most common cause of preterm labour is intrauterine fetal distress, that causes preterm termination of pregnancy, despite immaturity, and prematurity rate is 30-50 percent. We observed bad diabetes control in above mentioned classes.
