Abstract：
We analyzed the clinical characteristics and suicide-related factors of students who died by suicide in Korea in 2016-2020, based on teachers\' reports. Using data on total suicide deaths (N = 654, mean age = 16.0, 52.6% boys) collected by the Ministry of Education of Korea, we investigated the demographic and clinical characteristics and suicide-related factors of suicide deaths in students aged 9-18 years. Considering gender, more boys (52.6%, N = 344) died by suicide than girls (47.4%, N = 310). About 425 (65.0%) of the suicides were among high school students. The most common suicide method was jumping from a high place (70.6%, N = 454), followed by hanging (25.7%, N = 165). Additionally, 9.4% (N = 48) of the students who died by suicide had a history of attempted suicide, 13.4% (N = 73) had attempted self-harm, and 12.8% (N = 48) were acquainted with someone who had died by suicide. Teachers observed 20.6% (N = 120) of the suicide warning signs at school. Girls tended to have higher rates of attempted suicide, emotional problems, and psychiatric disorders than boys. This study was conducted with the largest sample of Korean suicide students observed at school. Effective suicide-related mental health training for teachers could contribute to suicide prevention in students.
摘要：
我们根据教师报告，分析了2016-2020年韩国学生自杀死亡的临床特征和自杀相关因素。使用韩国教育部收集的自杀死亡总数数据（N=654，平均年龄=16.0，男孩占52.6％），我们调查了9-18岁学生自杀死亡的人口统计学和临床特征以及自杀相关因素.考虑到性别,更多男孩(52.6%，N=344）死于自杀比女孩（47.4%，N=310）。约425（65.0％）的自杀是高中生。最常见的自杀方法是从高处跳楼(70.6%,N=454),其次是绞刑(25.7%，N=165）。此外,9.4%(N=48)死于自杀的学生有自杀未遂史,13.4%(N=73)曾尝试自残，12.8％（N=48）认识自杀死亡的人。教师在学校观察到20.6％（N=120）的自杀警告信号。女孩的自杀未遂率往往更高，情绪问题,和精神疾病比男孩。这项研究是在学校观察到的最大的韩国自杀学生样本进行的。对教师进行有效的与自杀相关的心理健康培训可能有助于学生的自杀预防。
