Abstract

Objective: This study aimed to explore the association between major depressive disorder (MDD) and suicide risk in patients with dementia.

Methods: A cohort of 625,218 individuals aged = 40 years with dementia was identified from Taiwan's National Health Insurance Research Database (NHIRD) between 2007 and 2018. After excluding prevalent cases in 2007, a nested case-control study enrolling 1,256 suicide cases and 5,022 matched controls was conducted. The frequencies of MDD-related outpatient or inpatient visits over a 7-year period preceding the event dates were calculated and analyzed for association using conditional logistic regression.

Results: Dementia comorbid with MDD was associated with increased suicide risk (adjusted OR [AOR]: 2.67), particularly in individuals with = 1.0 MDD episodes per year (AOR: 2.85). A similar association was observed only in individuals aged = 65 years and males, with a pronounced risk of suicide in those experiencing = 1.0 MDD episodes per year (AOR: 3.08 for individuals aged = 65 years; AOR: 3.28 for males). Conversely, the risk increase was evident with > 1.0 MDD episodes per year in those aged < 65 years (AOR: 3.04) and females (AOR: 2.45).

Conclusion: MDD is associated with suicide risk in patients with dementia. The strength of this association possibly varies with age and gender.

痴呆症患者自杀风险与重度抑郁障碍的关联：基于人群的嵌套病例对照研究》。

研究目的本研究旨在探讨重性抑郁障碍（MDD）与痴呆症患者自杀风险之间的关联：从台湾 "国民健康保险研究数据库 "中筛选出2007年至2018年期间年龄≥40岁的625218名痴呆症患者。在排除了 2007 年的流行病例后。随后，进行了一项巢式病例对照研究，纳入了 1,256 例自杀病例和 5,022 例匹配对照。研究人员计算了事件发生日期前 7 年内与痴呆症相关的门诊或住院就诊频率，并利用条件逻辑回归分析了两者之间的关联：结果：合并 MDD 的痴呆症与自杀风险增加有关（调整赔率比 [AOR]：2.67），尤其是每年 MDD 发作次数≤1.0 次的患者（AOR：2.85）。仅在年龄≥65 岁的人和男性中观察到类似的关联，每年 MDD 发作次数≤1.0 次的人有明显的自杀风险（年龄≥65 岁的人的 AOR：3.08；男性的 AOR：3.28）。相反，在结论年龄组中，每年 MDD 发作次数大于 1.0 次的风险明显增加：多发性抑郁与痴呆症患者的自杀风险有关，这种关联的强度可能因年龄和性别而异。
