The Incidence Trends of Chronic Diseases of the Tonsils and Adenoids in Kazakhstan

Abstract

Objective: To study the trends of chronic diseases of the tonsils and adenoids incidence in Kazakhstan.

Methods. The research material was compiled summary reporting form number 12 of Ministry of Health of the Republic of Kazakhstan on new cases of chronic diseases of the tonsils and adenoids (ICD-10 – J35), established for the first time. A retrospective study was used as the main method for studying the incidence of chronic diseases of the tonsils and adenoids. According to generally accepted methods of biomedical statistics, extensive, intensive and equalized indicators of the incidence of chronic diseases of the tonsils and adenoids were calculated.

Results. For 2009-2018 651,934 new cases of chronic diseases of the tonsils and adenoids were registered in the republic, of which were in children – 64.6%, teenagers – 9.5% and adults – 25.9%. The average annual incidence rate of chronic diseases of the tonsils and adenoids in the entire population of Kazakhstan was 383.3±8.1⁰/₀₀₀₀ (95%CI=367.4-399.1⁰/₀₀₀₀), and for population groups having been studied was: in children – 957.3±23.7⁰/₀₀₀₀ (95%CI=910.9-1003.7⁰/₀₀₀₀), among teenagers – 847.0±16.6⁰/₀₀₀₀ (95%CI=814.5-879.4⁰/₀₀₀₀) and the adult population 142.6±7.6⁰/₀₀₀₀ (95%CI=127.7-157.6⁰/₀₀₀₀). The difference in incidence between groups was statistically significant. Disease tended to decrease in all age groups: in children (Т=−1.8%), in adolescents (T=−1.1%) and in the adult population (Т=−5.5%).

Conclusion. According to the dynamics, chronic diseases of the tonsils and adenoids incidence in Kazakhstan has a decreased tendency. The results obtained are recommended to be taken into account by health authorities when making managerial decisions.
