2020년 자살 관련 지표들과 추이

Abstract

The aim of this study was updating 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. This study used five data sources to evaluate the trends of suicide-related indicators: Statistics Korea (1983–2020),Korean Wealth Panel Study (KOWEPS, 2012–2020), and Korea Health Panel Survey (KHP, 2010–2013, 2016–2018), Korean NationalHealth and Nutrition Examination (KNHANES, 2007–2013, 2015–2020), and Korean Community Health Survey (KCHS, 2008–2009, 2013,2017). The suicide rate per 100,000 population decrease from 26.9 in 2019 to 25.7 in 2020. Based on recently available data, the ratesof suicidal ideation were 1.48% (KOWEPS, 2020), 2.61% (KHP, 2018), 4.62% (KNHANES, 2019), and 6.96% (KCHS, 2017). Those ofsuicide attempt as were 0.07% (KOWEPS, 2020), 0.44% (KNHANES, 2020), and 0.32% (KCHS, 2017). Annual percentage change (APC)of suicide rate was -1.87% (Statistics Korea, 2011–2020). APC of suicidal ideation was -10.7% (KOWEPS, 2012–2020), -11.5% (KHP,2010–2013, 2016–2018), -14.7% (KNHANES, 2007–2013, 2015, 2017, 2019), and -2.5% (KCHS, 2008–2009, 2013, 2017). APC of suicideattempt was -11.3% (KOWEPS, 2012–2019), -5.2% (KNHANES, 2007–2013, 2015–2020), and -4.4% (KCHS, 2008–2009, 2013, 2017). Although the suicide rate in Korea has decreased compared to 10 years ago, it is still at a high level. Thus, continuous observationand appropriate suicide prevention policies are needed.
