The aim of this study was to examine the relation of mental, physical, and social wellbeing measures to death by suicide and self-harm (SH).
Using a cohort design, questionnaire data on 266,324 responders aged ≥ 45 years, living in NSW, Australia were linked to hospital and death databases during 2006-2017. Adjusted incidence rate ratios (IRR) were calculated.
Overall, 212 suicides and 723 SH episodes were observed. A dose-response relationship with suicidal behaviour was found for Kessler-10 Psychological Distress Scale; IRRs of 4.5 (95% CI 2.4-8.3) for suicide and 8.3 (95% CI 6.5-10.7) for SH were observed for scores of high versus low distress. Elevated rates were also observed for those reporting poor versus good or excellent health (suicide, IRR: 3.8, 95% CI 2.2-6.9; SH, IRR: 4.5 95% CI 3.4-6.1); being dependent versus not dependent on help with daily tasks (suicide, IRR: 2.4 95% CI 1.5-3.7; SH, IRR: 2.6 95% CI 2.0-3.3); being a current smoker (suicide, IRR: 1.8, 95% CI 1.1-2.9; SH, IRR: 2.9 95% CI 2.3-3.5) having versus not having male erectile problems (SH, IRR: 1.9 95% CI 1.4-2.5). Participants with ≥ 5 people versus one person to depend on had reduced suicidal behaviour (suicide, IRR: 0.5 95% CI 0.3-0.7, SH, IRR: 0.5 95% CI 0.4-0.6).
An active social network was linked to lower rates of suicide and self-harm. Adverse health, dependence on help, psychological distress were associated with higher rates of suicide and self-harm, while erectile problems were linked to an elevated rate of self-harm.
本研究旨在探讨心理、身体和社会健康指标与自杀和自我伤害（SH）死亡之间的关系。
使用队列设计，对 2006 年至 2017 年间居住在澳大利亚新南威尔士州的≥45 岁的 266324 名应答者的问卷调查数据与医院和死亡数据库进行了关联。计算了调整后的发病率比值（IRR）。
总体而言，观察到 212 例自杀和 723 例 SH 发作。Kessler-10 心理困扰量表得分与自杀行为呈剂量反应关系；高压力得分组的自杀和 SH 的 IRR 分别为 4.5（95%CI 2.4-8.3）和 8.3（95%CI 6.5-10.7），而低压力得分组的 IRR 分别为 3.8（95%CI 2.2-6.9）和 4.5（95%CI 3.4-6.1）。报告健康状况差或极好的人群与健康状况极好的人群相比，自杀的发生率也较高（IRR：3.8，95%CI 2.2-6.9；SH，IRR：4.5 95% CI 3.4-6.1）；与不需要帮助完成日常任务的人群相比，需要帮助的人群的自杀发生率更高（IRR：2.4 95% CI 1.5-3.7；SH，IRR：2.6 95% CI 2.0-3.3）；与不吸烟的人群相比，当前吸烟的人群的自杀发生率更高（IRR：1.8，95% CI 1.1-2.9；SH，IRR：2.9 95% CI 2.3-3.5）；与没有男性勃起功能障碍的人群相比，存在男性勃起功能障碍的人群的 SH 发生率更高（IRR：1.9 95% CI 1.4-2.5）。与依赖一个人相比，≥5 人依赖的人群的自杀和 SH 发生率较低（自杀，IRR：0.5 95% CI 0.3-0.7，SH，IRR：0.5 95% CI 0.4-0.6）。
一个活跃的社交网络与较低的自杀和 SH 发生率相关。不良健康状况、对帮助的依赖、心理困扰与较高的自杀和 SH 发生率相关，而勃起功能障碍与 SH 发生率的升高有关。
