Background: This study aimed to update suicide-related indicators, including the number of suicidal deaths, suicide rate, and theprevalence of suicidal ideation and suicide attempts. We observed trends in suicide-related indicators based on up-to-dateinformation.
Methods: This study used five data sources to evaluate the trends of suicide-related indicators: Statistics Korea (1983?2021), KoreanWealth Panel Study (KOWEPS, 2012?2021), and Korea Health Panel Survey (KHP, 2010?2013, 2016?2019), Korean National Health andNutrition Examination (KNHANES, 2007?2013, 2015?2021), Korean Community Health Survey (KCHS, 2008?2009, 2013, 2017, 2021).
Results: The suicide rate per 100,000 population increased from 25.7 in 2020 to 26.0 in 2021. The rates of suicidal ideation fromrecently available data were 4.28% (KNHANES, 2021), 6.52% (KCHS, 2021), 1.61% (KOWEPS) and 7.10% (KHP, 2019). The suicidalattempts rates were 0.46% (KNHANES, 2021) and 0.34% (KCHS, 2021). The annual percentage change (APC) of suicide rate showedthat suicide rates increased in the younger population (APC=9.02% in <19 years, APC=5.13 in 20?39 years) although the ratesdecreased in the older population (APC=-3.37 in 60?79 years, APC=-2.25 in >80 years).
Conclusion: The suicide rate and related indicators increased in 2021 compared to 2020. Thus, continuous observation andappropriate suicide prevention policies as well as studies about the factors that affected the increase in 2021 are needed.
