Findings from studies examining the relationship between dementia and suicide have been inconsistent. This study examined the characteristics, precipitants, and risk factors for suicide among persons with dementia.
Data from the Georgia Alzheimer's Disease and Related Dementia registry were linked with 2013 to 2016 data from Georgia Vital Records and Georgia Violent Death Reporting System. Descriptive statistics were calculated and logistic regression was used to examine risk factors for suicide.
Ninety-one Georgia residents with dementia who died by suicide were identified. Among decedents with known circumstances, common precipitants included depressed mood (38.7%) and physical health problems (72.6%). Suicide rate among persons with dementia was 9.3 per 100 000 person-years overall and substantially higher among those diagnosed in the past 12 months (424.5/100 000 person-years). Being male, dementia diagnosis before age 65, and a recent diagnosis of dementia independently predicted suicide, but not depression or cardiovascular diseases.
Prevention strategies that identify at-risk individuals, provide support, and ensure continuity of care for persons diagnosed with dementia may help reduce suicide in this population.
研究痴呆症和自杀之间关系的结果一直不一致。本研究检查了痴呆症患者自杀的特征、诱因和危险因素。
将来自佐治亚州老年痴呆症和相关痴呆症登记处的数据与 2013 年至 2016 年佐治亚州生命记录和佐治亚州暴力死亡报告系统的数据相联系。计算了描述性统计数据，并使用逻辑回归检查了自杀的危险因素。
确定了 91 名在佐治亚州自杀的痴呆症居民。在已知情况的死者中，常见的诱因包括情绪低落（38.7%）和身体健康问题（72.6%）。总体而言，痴呆症患者的自杀率为每 10 万人年 9.3 例，在过去 12 个月内被诊断为痴呆症的患者的自杀率要高得多（424.5/10 万人口/年）。男性、65 岁前被诊断为痴呆症以及最近被诊断为痴呆症独立预测了自杀，但与抑郁症或心血管疾病无关。
预防策略可以识别高危人群，提供支持，并确保为被诊断为痴呆症的人提供持续的护理，这可能有助于减少该人群的自杀。
