THE PREVALENCE OF OBSTETRIC RISK FACTORS AND THEIR IMPACT ON ADVERSE PREGNANCY OUTCOMES

Abstract

Background. To study the prevalence of obstetric and gynecological factors and their impact on the risk of adverse pregnancy outcomes in the Krasnoyarsk region. Materials and methods. The data of perinatal monitoring of the Krasnoyarsk territory, functioning on the basis of the Krasnoyarsk regional medical information and analytical center, are used. The analysis included data on 122 250 cases of pregnancy in the period from 2014 to 2017 All the analyzed cases of pregnancy were divided into 2 groups: group I – cases of pregnancy with adverse outcomes (8 of 290 cases), group II – cases of pregnancies with favorable outcomes (113 960 cases). The influence of the following factors on the development of adverse pregnancy outcomes was analyzed: the number of births and abortions in the history, the presence of premature births, stillbirth, neonatal death in the history, the presence of uterine malformations, chronic inflammatory diseases, ovarian tumors, uterine fibroids and scars, anemia of mild, moderate and severe severity, as well as the presence in the history of in vitro fertilization. Result. The results of the study indicate that all the factors studied have an impact on the risk of adverse pregnancy outcomes. To the greatest extent, this risk is influenced by the presence of two or more preterm births in the history, uterine malformations and a history of stillbirth. Conclusion. The use of information on the prevalence and impact of various factors on the risk of adverse pregnancy outcomes will most effectively route pregnant women to levels of care to reduce the number of these outcomes. The results show that the risk of adverse pregnancy outcomes is influenced by a fairly wide range of factors. In this case, each factor has a different degree of impact on the risk.
