The trend in neurological diseases in Moscow adolescents, before and after the COVID-19 pandemic

Introduction. During the pandemic the stress level among adolescents has increased significantly due to the uncertainty of the future, awareness for the health of their friends and family, and changes in the educational process and daily routine. In addition, increased time spent indoors, lack of physical activity, poor nutrition and sleep disorders also contribute to the deterioration of the nervous system of adolescents. It is necessary to conduct additional research and monitoring of the incidence of the nervous system among adolescents in the post-pandemic period to assess and prevent possible negative consequences on their health. The purpose is to analyze the trend in the incidence of diseases of the nervous system in adolescents, including gender differences, using the example of Moscow over the period before and after the Covid-19 pandemic. Materials and methods. The following methods are applied: summary and grouping, calculation of relative and average values, dynamics series, distribution indices, analysis of statistical aggregates. The data of the federal statistical observation form No. 12 “Information on the number of diseases registered in patients living in the service area of a medical institution” for 2016–2023 was used. Results. Due to the COVID-19 pandemic in Moscow, there was an increase in the incidence during the “post-covid” period. In 2021–2023, the gain in the incidence of disorders of the autonomic nervous system (ANS) is twofold higher than over the five-year “pre-covid” period. Research limitations. The study has regional (Moscow) limitations. Conclusions. The average Moscow rates of the morbidity of the nervous system, while remaining lower than the Russian ones, are approaching them in trend. There were no significant changes in the difference between diseases in boys and girls, but in terms of episodic and paroxysmal disorders, the trend in convergence of indices was noted.
