Epidemiology of diseases of the skin and subcutaneous tissue and specialized medical care provided in three age groups of the population in 2010–2020 in the Russian Federation

Rationale and aim of the study. The incidence of diseases of the skin and subcutaneous tissue is in the forth place in the Russian Federation. The aim of the study is to investigate the prevalence and incidence of diseases of the skin and subcutaneous tissue, the structure and dynamics of medical care provided to the population of three age groups in 2010– 2020.Materials and methods. Analysis of national statistical monitoring data and rates calculated for 2010–2020. The calculations and analysis were carried out for the entire population of the Russian Federation, and for the population of three age groups: children 0–17 years old, adults of working age and adults of over working age using the approach approved by Federal State Statistics Service.Results. In 2010–2019 there was a decrease in the number and incidence of diseases of the skin and subcutaneous tissue among children and adults of working age. In the structure of diseases of the skin and subcutaneous tissue, the proportion of diseases among population over working age is increasing. The number of 24-hour hospital admissions for diseases of the skin is decreasing among children and adults of working age. In contrast, there was an increase in the number of skin diseases and hospital admissions of patients over the working age.Conclusion. In the Russian Federation, the highest prevalence and incidence rates of diseases of the skin and subcutaneous tissue are registered in the group of children 0–17 years old. At the same time, there is a steady decline of both rates among population of this age group. There is an increase in the number of diseases and as a consequence in the need and volume of specialized medical care in 24-hour hospitals provided to the population of over the working age. The COVID-19 pandemic has led to decrease in prevalence and incidence rates, and number of hospital admissions for skin diseases similar in three age groups.
