Epidemiological Aspects of Suicide in the East Kazakhstan Region

Abstract

Objective: To study the trends of mortality from intentional self-harm in the East Kazakhstan region.

Methods. The main sources of information were the materials of the state registration of the deceased as a whole from intentional self–harm (ICD 10 - X60-84) for 2004-2013. Materials related to the East Kazakhstan region were analyzed. A retrospective study using descriptive and analytical methods of modern epidemiology was used as the main method in the study of mortality from intentional self-harm.

Results. In 2004-2013, 38,276 cases of intentional injuries were registered in Kazakhstan, of which only 5998 (15.7%) suicides occurred in the East Kazakhstan region. The average age of those who died from suicide was 40.4±0.5 years. The average annual crude mortality rates from intentional self–harm among both sexes amounted to 42.2±2.4⁰/₀₀₀₀ (95%CI=37.5-47.0). In dynamics, the crude mortality rate for both sexes decreased, and the average annual rate of decline was T=−5.0%. Age-sex differences in suicide mortality rates were revealed. The analysis of age-related mortality rates from intentional self-harm in both sexes in the studied region showed a unimodal increase with a peak in the age group of 30-49 years.

Conclusion. The analysis of mortality from suicide showed that in the East Kazakhstan region, mortality is decreasing significantly. The data obtained make it possible to monitor trends and changes in suicide mortality. This helps to assess the effectiveness of measures to reduce the risk of suicide and adjust strategies and programs depending on changing conditions.
