To determine the medical and social characteristics of women undergoing termination of pregnancy earlier than 6 weeks and to comparatively evaluate the efficacy and safety of different mifepristone doses for medical abortion (МА). Subjects and methods. A prospective comparative study of the efficacy of different mifepristone doses (600 and 200 mg) for a MA regimen was conducted in 337 and 130 women undergoing termination pregnancy less than 6 weeks’ gestation, respectively. Sonography, vaginal smear bacterioscopy, and in some cases, if indicated, vacuum aspiration, pathomorphological examination of the uterine material were performed. Results. The medico-social portrait of women preferring a reduced mifepristone dose is presented with their late reproductive age (35-43 years), blue-collarjobs, unemployed, mainly legally married women, and parous women who had fewer artificial abortions and a history of MA. Previous genital inflammatory diseases and reproductive losses were determinants in women who are a group at high-risk for post-abortion infectious complications (incomplete abortion and endo-metritis), However, the frequency of complications of MA did not depend on the used dose of mifepristone. The low frequency of complications of MA was ascertained to be associated with a package of preventive measures, such as sanitation of the lower genital tract, ultrasound monitoring of the quality of an abortion.</p></abstract><trans-abstract xml:lang="ru"><p>Цель исследования. Определить медико-социальную характеристику женщин, прерывающих беременность до 6 недель, провести сравнительную оценку эффективности и безопасности различных доз мифепристона для медикаментозного аборта (МА). Материал и методы. Проспективное сравнительное исследование эффективности различных доз мифепристона: 600 мг (337 женщин) и 200 мг (130) в схеме прерывания беременности до 6 недель. Выполнены: сонография, бактериоскопия мазков влагалищного секрета, в отдельных случаях (по показаниям) - вакуумная аспирация, патоморфологическое исследование материала из полости матки. Результаты исследования. Медико-социальный портрет женщин, отдавших предпочтение редуцированной дозе мифепристона, представлен поздним репродуктивным возрастом (35-43 года), наличием рабочих специальностей и неработающих, преимущественно состоящих в официальном браке, а также рожавшими женщинами, реже прибегавшими к искусственному аборту и уже имевшими опыт медикаментозного аборта в анамнезе. Воспалительные заболевания гениталий и репродуктивные потери в прошлом были определяющими в принадлежности к группе высокого инфекционного риска послеабортных осложнений (неполного аборта и эндометрита). Однако уровень осложнений МА не зависел от используемой дозы мифепристона. Установлено, что низкий уровень осложнений МА связан с комплексом профилактических мероприятий: санацией нижних отделов генитального тракта, ультразвуковым контролем качества аборта. Заключение. Доза 200 мг мифепристона для МА так же эффективна, как и стандартная 600 мг для прерывания беременности до 6 недель и с точки зрения клинической и экономической целесообразности оправдана и перспективна.</p></trans-abstract><kwd-group xml:lang="en"><kwd>medical abortion</kwd><kwd>reduced mifepristone dose</kwd><kwd>abortion complications</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>медикаментозный аборт</kwd><kwd>редуцированная доза мифепристона</kwd><kwd>осложнения аборта</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Jones R.K., Kooistra K.
