Epidemiological characteristics of mental disorders in the population of the Omsk region. A descriptive study (2010−2022)

Aim. Assessment of epidemiological manifestations of mental disorders in the Omsk region for the period 2010-2022. Materials and methods. A retrospective epidemiological analysis of data from the federal statistical observation form No. 10 «Information on diseases with mental disorders and behavioral disorders (except for diseases related to the use of psychoactive substances)» for the Omsk region for 2010−2022 was carried out. The incidence rates (relative prevalence) of mental disorders per 100,000 population were calculated for the Omsk region as a whole and municipalities, taking into account the distribution of cases among men and women, by age groups 0−19 years, 20−39 years, 40−59 years, 60 years and older, using relative values. Results. The incidence of mental disorders in the Omsk region was 3213.5 per 100 thousand people. Among both sexes, the incidence of PR in the region had a moderate downward trend (Tsn = 1.25 %; p < 0.001). There was a moderate downward trend (Tsn = 1.55 %; p < 0.001) in the incidence of psychoses and dementia among men. There were no trends in the female population and the territory of residence (Tsn. = 0.35 %; Tsn. = 1.07 % in urban areas, p < 0.001 and Tsn. = 0.8 % in rural areas, p < 0.001, respectively). In the younger (0−19 years old) and older (40−59 years old, 60 years old and older) age groups, mental disorders of a non-psychotic nature were in the lead in the structure of the incidence of PR, while mental retardation was a priority at the age of 20-39 years. Conclusion. The incidence of mental disorders in the Omsk region exceeded the national average (by 21.5 %). In dynamics, the trend towards a decrease in the incidence of mental disorders in the region was observed among both sexes, but was largely due to a decrease in this indicator in men. In the age structure of patients with mental disorders in the Omsk region, people aged 20−39 years were in the lead for 2010−2022. A moderate tendency to an increase in the incidence of PD was revealed in the age groups of 60 years and older throughout the region (Tpr. = 1.6 %; p < 0.001), as well as in people aged 40−59 years living in rural areas.
