Dynamics of benign mammary dysplasia incidence in women over the working age at regional level

Abstract

Objective. To determine the epidemiological patterns of the incidence and prevalence of benign mammary dysplasia (BMD) in the adult female population over the working age in Sverdlovsk Region and the city of Ekaterinburg in 2012–2021.
 Materials and methods. The incidence and prevalence of BMD in Sverdlovsk Region and Yekaterinburg in 2012–2021 were analyzed in comparative aspect.
 Results. In 2012–2019 BMD incidence among women over the working age was characterized by a tendency to grow in Sverdlovsk Region. Regarding Yekaterinburg, this index was – 0.9 %. The prevalence of BMD in 2014–2019 in the region and the city statistically significantly exceeded the values in 2012 (p 0.001). The average rate of growth in the region and city had a marked dynamics of increase and was 8.08 % and 7.84 %, respectively. In 2020–2921, there was observed a sharp decrease in the regional and city indices. The average rate of growth was – -33.11 %, prevalence – -11.21 %.
 Conclusions. In 2012–2019, the BMD incidence in the female population over the working age was characterized by a moderate tendency to grow in Sverdlovsk Region and the absence of dynamics in Yekaterinburg. Prevalence had a pronounced dynamics of increase in the city and region, that proves a chronic character of the disease and organization of follow-up observation among patients.
