To examine factors associated with the choice of public location over home to die by suicide.
This study used a case-control design. Data on suicides that occurred between 2001 and 2017 in Australia were extracted from the National Coronial Information System. Cases were suicides that occurred in public places and controls were suicides that occurred at home. Logistic regression models were used to estimate the associations between suicide location and several sociodemographic variables, depending on whether hotel rooms were included in or excluded from public places.
In total, 25.2% of 42,656 suicides occurred in public places including hotel rooms, 69.3% at home, and 5.4% in nonpublic places other than at home (e.g., inpatient ward or correctional facilities). Excluding suicides in hotel rooms from public places, 1.6% points of suicides in public places moved to nonpublic places other than at home. In multivariable regression models regardless of scenarios, males (compared with females) had higher odds of dying by suicide in public places, while those who were divorced/separated/widowed (compared with married people), those who were older (aged 30-54, and aged 55 and above, compared with under 30 years), and those who were unemployed or not in the labor force (compared with employed people) had lower odds of suicide in public places.
The findings should be used to inform the design of strategies to prevent suicides in public places.
研究与选择在公共场所而非家中自杀死亡相关的因素。
本研究采用病例对照设计。从澳大利亚国家死因信息系统中提取2001年至2017年间发生的自杀事件数据。病例为在公共场所发生的自杀事件，对照为在家中发生的自杀事件。根据公共场所是否包括酒店房间，使用逻辑回归模型估计自杀地点与几个社会人口学变量之间的关联。
在42,656例自杀事件中，总计25.2%发生在包括酒店房间在内的公共场所，69.3%发生在家中，5.4%发生在除家中以外的非公共场所（如住院病房或惩教设施）。若将公共场所中的酒店房间自杀事件排除在外，1.6%的公共场所自杀事件转移至除家中以外的非公共场所。在多变量回归模型中，无论哪种情况，男性（与女性相比）在公共场所自杀死亡的几率更高，而离婚/分居/丧偶者（与已婚者相比）、年龄较大者（30 - 54岁以及55岁及以上，与30岁以下相比）以及失业或不在劳动力队伍中的人（与就业者相比）在公共场所自杀的几率较低。
这些研究结果应用于为预防公共场所自杀的策略设计提供信息。
