Peculiarities of placental condition during preterm birth in overweight and obese women as related to ecology

We performed the histic observation of pregnant women placetae to investigate the impact of overweight and obesity on the placental condition. Group 1 included 121 cases of BMI=18,5-24,9, group 2 comprised 69 cases of BMI=30 and above. The following parameters were observed: adequacy of the placental condition to the gestational age, abnormal immaturity of placental villi, pathologic placental immaturity, angiostenosis of the umbilical cord, degenerative-dystrophic changes, compensatory reactions, microbial contamination of the placenta, funiculitis, placental chorioamnionitis, parietal chorioamnionitis, parietal deciduitis, basal deciduitis, intervillusitis, villusitis, pathogens, other placental pathology (nidal hypo-vascularisation, obliterating angiopathy, intervillous haemorrhage, fetal integument haemorrhage, dilation of the stem villi). The results of testing showed that morphological condition of obese women’s placentae comprised circulatory, degenerative-dystrophic and inflammatory injuries, degree of manifestation increasing with the increase of BMI.
