Abstract:
The aim of the study was to establish a link between the timing of preterm birth and
clinical groups of women of different ages.
There were demonstrated the differences in the incidence of preterm birth among
women of different reproductive ages in our study were not found (p>0,05). The rate of
cesarean delivery was higher (p>0,05) in women who gave birth from 22 to 27 weeks of
gestation. The threatened abortions in the I and II trimesters were observed in women of all
groups. In women of the I and II groups the phenomena of placental dysfunction in the form
of infarcts and retroplacental hematomas on the background of various urogenital infections
were revealed. Indicators of compensatory-adaptive response in the placenta are better
developed in women who gave birth at 33-37 weeks. Developmental pathology and location
of the umbilical cord occurred in women whose children were born in the terminals from 22
to 33 weeks of pregnancy. Mortality among children at 22-27 weeks was higher in parallel
with a higher percentage of cesarean sections in the same group compared to the other two
groups
