Aim. To study the effect of maternal reproductive factors on the risk indicators of CA, PE, SGA fetus and PB, assessed during prenatal screening using the Astraia Obstetrics module. Materials and methods. Of the 11,841 pregnant women who were prenatal screened, 18.53% of the patients had at high risk of the outcomes studied (frequency 1: 100 and above). The subgroup of isolated high risk for CA included 69, PE — 66, SGA fetus — 48, PB — 52 patients. From the group of patients with low risk, 208 patients were selected for the control group by the method of stratified randomization by age. Results. Among extragenital diseases, the most common in all high-risk subgroups were: hypertension (AH) I and II degree — 31–47% versus 4.8% of the control group (p &lt; 0.05), varicose veins of the lower extremities (VVLE) — 17–30% vs. 5.3% in the control group (p &lt; 0.05), a history of ovarian tumor — 12–33% vs. 3% in the control group (p &lt; 0.05). In the high-risk subgroups for the development of CA, PE and SGA fetus, fibroids uterus and iron deficiency anaemia (IDA) were more common compared to control: 10–41% vs. 1% (p &lt; 0.05) and 10–17% vs. 3% (p &lt; 0.05), respectively (p &lt; 0.05). Primiparas with a history of pregnancy were more common in subgroups with a high risk of CA (33%) and PR (35%) versus 17% in controls. Conclusion. An association has been established between high risk for all the outcomes studied and AC, VVLE, history of ovarian tumor. High-risk subgroups for CA, PE and SGA fetus have a higher incidence of uterine fibroids and IDA compared to control.</p></abstract><trans-abstract xml:lang="ru"><p>Влияние материнских факторов на показатели повышения риска хромосомных аномалий (ХА), преэклампсии (ПЭ), задержки роста плода (ЗРП) и преждевременных родов (ПР) при проведении пренатального скрининга изучено недостаточно.Цель. Изучить влияние материнских репродуктивных факторов на показатели риска по ХА, ПЭ, ЗРП и ПР, оцененных при проведении пренатального скрининга с помощью модуля Astraia Obstetrics.Материалы и методы. Из 11 841 беременной, которым проведен пренатальный скрининг, высокий риск изученных исходов (частота 1:100 и выше) отмечен у 18,53% пациенток. В подгруппу изолированного высокого риска по ХА включены 69, ПЭ — 66, ЗРП — 48, ПР — 52 пациентки. Из группы пациенток с низким риском методом стратифицированной рандомизации по возрасту были отобраны 208 в группу контроля.Результаты. Среди экстрагенитальных заболеваний наиболее частыми во всех подгруппах с высоким риском были: артериальная гипертензия (АГ) I и II степени — 31–47% против группы контроля 4,8% (p &lt; 0,05), варикозное расширение вен нижних конечностей (ВРВНК) — 17–30% против 5,3% в группе контроля (p &lt; 0,05), опухоль яичников в анамнезе — 12–33% против 3% в группе контроля (p &lt; 0,05). В подгруппах высокого риска по развитию ХА, ПЭ и ЗРП миома матки и железодефицитная анемия (ЖДА) чаще встречались по сравнению с контролем: 10–41% против 1% (p &lt; 0,05) и 10–17% против 3% (p &lt; 0,05) соответственно. Первородящие с наличием беременности в анамнезе чаще встречались в подгруппах по высокому риску ХА (33%) и ПР (35%) против 17% в контроле (p &lt; 0,05).Заключение. Установлена ассоциация между высоким риском по всем изученным исходам и АГ, ВРВНК, опухолью яичников в анамнезе. В подгруппах высокого риска по ХА, ПЭ и ЗРП отмечена бóльшая частота миомы матки и ЖДА по сравнению с контролем.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>пренатальный скрининг</kwd><kwd>осложнения беременности</kwd><kwd>материнские факторы</kwd><kwd>программно-аппаратный комплекс «Астрайа»</kwd><kwd>хромосомные аномалии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>prenatal screening</kwd><kwd>pregnancy complications</kwd><kwd>maternal factors</kwd><kwd>a fetal medicine software program Astraia</kwd><kwd>chromosomal abnormalities</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Livrinova V., Petrov I., Samardziski I., et al.
