Abstract

Objectives
The aim of this study is to identify the prevalence of parasuicide and deliberate suicide attempts in the general population of Korea, as well as their associations with sociodemographic risk factors and mental disorders.
Methods
This study utilized data from the 2021 National Mental Health Survey of Korea. The survey was conducted between June and August 2021, involving 5,511 respondents aged 18 to 79 years living in communities. The Korean version of the Composite International Diagnostic Interview (K-CIDI) was used as the survey instrument. Logistic regression analysis was employed for statistical analysis.
Results
The prevalence of parasuicide was 1.1%, and that of deliberate suicide attempts was 0.9%. The risk of parasuicide increased among younger age, while no significant associations with other sociodemographic factors were found. The risk of deliberate suicide attempts was associated with being divorced, separated or widowed and low income. Both parasuicide and deliberate suicide attempts were associated with depressive disorders, anxiety disorders, alcohol use disorders and nicotine use disorders.
Conclusions
The sociodemographic risk factors of parasuicide and deliberate suicide attempts are distinct. This study provides valuable insights into the mental disorder-related traits associated with parasuicide and deliberate suicide attempts, which could be useful in developing future suicide prevention programs.
