Dynamics of sickness rate in 15–17- year-old girls in the Russian Federation

The children’s health condition in the Russian Federation, including adolescents, has been characterized by negative trends in the past thirty years.Objective. To identify the main trends in sickness rate (both total and registered for the first time) in 15–17-year-old girls in the Russian Federation, as well as to track the quantity and dynamics of chronicity of diseases by classes and types.Material and methods. The authors analyzed the data of form №12 of the federal statistics in 2000–2017 using the descriptive statistics method.Results. The researchers revealed a significant increase both in the total sickness rate from 1613,8 to 2532,5 per 1,000 girls (by 56,9%) and in the sickness rate registered for the first time from 967,5 to 1577,3 per 1,000 girls (by 63,0%). The increase in total incidence is observed in the most classes of diseases: neoplasms (2,4 times), injuries, poisoning and some other consequences of external causes (2,4 times), congenital anomalies (malformations; 2,3 times), cardiovascular diseases (2 times), diseases of the musculoskeletal system and connective tissue (2 times). Also there was revealed the increase in the incidence registered for the first time in the overwhelming majority of classes of diseases, for example: injuries, poisoning and some other consequences of external causes (2,5 times), diseases of the nervous system (2,2 times), cardiovascular diseases (2 times), neoplasms (2 times), diseases of the ear and mastoid process (2 times), diseases of the musculoskeletal system and connective tissue (1,9 times). High index of the chronicity for all classes of diseases reflect the initially high level of chronic pathology in 15–17-year-old girls, which is an unfavorable characteristic of their health condition. Having analyzed the chronization index the authors revealed its maximum growth for congenital anomalies (malformations; by 31,1%) and neoplasms (by 23,0%), and for certain nosologies: menstrual disorders (5,8 times) and renal failure (4,2 times).Conclusion. The health of children, and especially adolescents, determines the national health in the nearest future; therefore, its preservation and improvement require thorough attention
