However, the persistence of HPV may not be sufficient for the occurrence of malignant transformation, and there may be other exogenous or endogenous factors that, in combination with the virus, increase the risk of developing and progressing cervical neoplasia.<bold>Objective:</bold> identification of risk factors that modulate the course of low-grade squamous intraepithelial lesions (LSIL) in women of reproductive age.<bold>Materials and methods.</bold> In 110 women aged 18 to 45 years with a diagnosis of LSIL, we evaluated the impact of risk factors (sexual behavior, reproductive function, contraceptive methods, smoking, HPV infection) on the course of the process (recovery, persistence or progression) during the 12-month follow-up period. HPV testing was performed by real-time PCR.<bold>Results.</bold> The average age of the study participants was 31.55 ± 7.17 years. Our observations showed that frequent artificial abortions, the practice of risky sexual behavior (early sexual debut, frequent change of sexual partners) increased the risk of persistence and progression of mild cervical cytological abnormalities. The use of oral contraceptives, barrier contraception and smoking did not affect the outcome of the disease.The prevalence of HPV among women with LSIL was 70.91 % (78/110). The predominant types were HPV 16 (35.45 %), HPV 33 (12.73 %) and HPV 18 (12.73 %). HPV 16 was more common in the progression group (62.50 %) than in the regression and persistence groups (14.63 % and 43.40 %, p &lt;0.05). Progression of neoplasias was more often observed in patients with signs of multiinfection of the cervical epithelium with HPV. Single HPV infection was higher in the group of recovered women.<bold>Conclusions.</bold> The study found that a large number of induced abortions, the practice of risky sexual behavior, the presence of HPV type 16 and multiple HPV infection are factors contributing to the persistence of LSIL and progression to HSIL. These data may be useful for the management of women with mild cervical cytological abnormalities.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение.</bold> Инфицирование онкогенными типами вируса папилломы человека (ВПЧ) является ведущей причиной рака шейки матки и его непосредственных предшественников – плоскоклеточных интраэпителиальных поражений. Однако персистенции ВПЧ может быть недостаточно для возникновения злокачественной трансформации, и могут существовать другие экзогенные или эндогенные факторы, которые в сочетании с вирусом повышают риск развития и прогрессирования цервикальных неоплазий.<bold>Цель исследования</bold> – выявление факторов риска, модулирующих течение плоскоклеточных интраэпителиальных поражений низкой степени (low-grade squamous intraepithelial lesion, LSIL) у женщин репродуктивного возраста.<bold>Материалы и методы.</bold> У 110 женщин в возрасте от 18 до 45 лет с диагнозом LSIL мы оценили влияние факторов риска (сексуального поведения, репродуктивной функции, методов контрацепции, курения, ВПЧ-инфекции) на течение процесса (выздоровление, персистирование или прогрессирование) в период 12 мес наблюдения. Тестирование на ВПЧ проводили методом полимеразной цепной реакции в реальном времени.<bold>Результаты.</bold> Средний возраст участниц исследования составил 31,55 ± 7,17 года. Наши наблюдения показали, что частые искусственные аборты, практика рискованного сексуального поведения (ранний сексуальный дебют, частая смена половых партнеров) увеличивали риск персистенции и прогрессирования LSIL. Применение оральных контрацептивов, барьерная контрацепция и курение не влияли на исход заболевания.Распространенность ВПЧ среди женщин с LSIL составила 70,91 % (78/110). Преобладающими типами ВПЧ были 16-й (35,45 %), 33-й (12,73 %) и 18-й (12,73 %). ВПЧ 16-го типа встречался чаще в группе прогрессирования (62,50 %), чем в группах регресса и персистенции (14,63 и 43,40 %; p &lt;0,05). Прогрессирование неоплазий чаще наблюдалось у пациенток с признаками мультиинфицирования цервикального эпителия ВПЧ. Одиночное инфицирование ВПЧ было выше в группе выздоровевших женщин.<bold>Выводы.</bold> В ходе исследования выявлено, что большое количество искусственных абортов, практика рискованного сексуального поведения, наличие ВПЧ 16-го типа и множественная ВПЧ-инфекция являются факторами, способствующими персистенции LSIL и прогрессированию до неоплазии высокой степени. Эти данные могут быть полезны для ведения женщин с LSIL.</p></trans-abstract><kwd-group xml:lang="en"><kwd>human papillomavirus</kwd><kwd>risk factors</kwd><kwd>low-grade squamous intraepithelial lesion</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>вирус папилломы человека</kwd><kwd>факторы риска</kwd><kwd>плоскоклеточные интраэпителиальные поражения низкой степени</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">1.
