Background. Information on the incidence of cervical intraepithelial neoplasia (CIN) is relevant for planning and evaluating the effectiveness of medical care at the stage of secondary prevention of cervical cancer. Aim. To analyze the incidence of CIN and benign diseases of the cervix: erosion and ectropion, leukoplakia, polyp, according to medical organizations in Yekaterinburg in 2013–2019. Materials and methods. A descriptive epidemiological study of the incidence of cervical pathology in the population of women in Yekaterinburg in 2013–2019 was conducted. The forms of Federal Statistical Observation No. 12 “Information on the number of diseases registered in patients living in the service area of a medical organization”, in terms of erosion and ectropion, and data from the city’s women’s consultations on the number of cases of CIN, leukoplakia and cervical polyp were examined. Information on the number of female population of the city from Sverdlovskstat was used. Results. The primary incidence of CIN increased throughout the follow-up period. The indicator increased by 1.7 times compared to 2013 (p < 0.001) in 2016, it had a maximum value in 2019 – 215.5 per 100 thousand women and was 3.2 times more than in 2013 (p < 0.001). The dynamics of the primary incidence of other types of cervical pathology: ectropion, leukoplakia and cervical polyp, was characterized by the absence of significant changes (p > 0.05) in 2013–2019. The increase in the overall incidence of CIN was registered from 2014 to 2019 in comparison with 2013 (p < 0.001). The indicator of the overall incidence of CIN in 2019 was 2.1 times higher than in 2013 (p < 0.001). Conclusions. The growth of primary and total incidence of CIN in the population of Yekaterinburg women noted since the beginning of the XXI century continued in 2013–2019. The primary incidence rate of CIN had the maximum value in 2019. The increase in the incidence of CIN is associated with the natural spread of the disease, accessibility and improvement in the quality of medical care.
