In 2018, South Korea's suicide mortality rate was 26.59 deaths per 100 000 people; this figure is 2.2 times higher than that of the year 2000, during which 12.22 deaths per 100 000 people were ascribed to suicide. This study aims to observe the trend of disease burden in years of life lost (YLL) due to suicide from 2000 to 2018 in South Korea and investigate the related sociodemographic risk factors.
This quantitative research used secondary data-including claim data, cause of death statistics, life tables and census data-from national health insurance corporation and Statistics Korea. Based on the methodology of Korean National Burden of Disease study, this study used an incidence-based approach to measure YLL.
The total YLL due to suicide during the last two decades was 4 298 886 years; the average YLL per death was 18.65 years. The YLL rate per 100 000 people was 482 (male: 664, female: 300) in 2018, 1.7 times higher than the 387 (male 387, female 183) in 2000. Low education levels and non-marital status were shown to be related to the increase in YLL rate.
These results show the increasing disease burden of suicide in South Korea and suggest the necessity of more in-depth research to analyse correlation and causation with sociodemographic risk factors.
2018年，韩国的自杀死亡率为每10万人中有26.59人死亡；这一数字比2000年高出2.2倍，2000年每10万人中有12.22人死于自杀。本研究旨在观察2000年至2018年韩国因自杀导致的寿命损失年数（YLL）的疾病负担趋势，并调查相关的社会人口统计学风险因素。
这项定量研究使用了来自国家健康保险机构和韩国统计局的二手数据，包括理赔数据、死亡原因统计、生命表和人口普查数据。基于韩国国家疾病负担研究的方法，本研究采用基于发病率的方法来衡量YLL。
过去二十年中，自杀导致的YLL总数为4298886年；每例死亡的平均YLL为18.65年。2018年，每10万人的YLL率为482（男性：664，女性：300），比2000年的387（男性387，女性183）高出1.7倍。低教育水平和非婚姻状况与YLL率的增加有关。
这些结果表明韩国自杀的疾病负担在增加，并表明有必要进行更深入的研究，以分析与社会人口统计学风险因素的相关性和因果关系。
