The objective of the study is to understand the characteristics of people who died by different suicide methods in Toronto, Canada. Suicide cases were identified by the Office of the Chief Coroner of Ontario (1998-2020). Demographic and clinical variables were retrieved. All suicide deaths were classified into different groups based on suicide method. Bivariate analyses and multinomial logistic regressions were performed to compare their demographic and clinical characteristics. Hanging (N = 1721), jumping from height (N = 1280), and poisoning (N = 955) were the most common suicide methods in Toronto. Those who died by hanging were more likely to be married or in common law relationships, live with others, experience employment/financial/academic-related stressors and die at home. People who died by jumping from height had a higher likelihood of having a psychiatric and/or emergency department visit in the past week and having schizophrenia or related disorders/symptoms. People who died by poisoning had higher odds of being female and leaving suicide notes. They were also more likely to have previous suicide attempts, experience depression and/or bipolar disorder and have physical conditions. Specific suicide prevention strategies should be designed and implemented to account both for commonalities and differences among people who die by different suicide methods.
本研究旨在了解加拿大多伦多不同自杀方法导致死亡人群的特征。自杀案例由安大略省首席验尸官办公室(1998-2020 年)确定。检索了人口统计学和临床变量。根据自杀方法将所有自杀死亡分为不同组。进行了双变量分析和多项逻辑回归,以比较其人口统计学和临床特征。在多伦多,最常见的自杀方法是上吊(N=1721)、跳楼(N=1280)和中毒(N=955)。上吊自杀者更有可能已婚或同居、与他人同住、经历就业/财务/学业相关压力源以及在家中死亡。跳楼自杀者过去一周内更有可能有精神科和/或急诊就诊史,且患有精神分裂症或相关障碍/症状。中毒自杀者女性和留有自杀遗言的可能性更高。他们也更有可能有过自杀企图,患有抑郁症和/或双相情感障碍以及身体疾病。应设计和实施特定的自杀预防策略,既要考虑到不同自杀方法导致死亡人群的共同点,也要考虑到其差异。
