In Sweden, 2,296,000 firearms were legally owned by private persons in 2017 and there were 150,000 persons living with a dementia diagnosis. A proportion of these persons owning a firearm may pose safety concerns.
The aim was to describe firearm ownership in persons with dementia in Sweden and examine which characteristics are explaining physicians' decision to report a person to the police as unsuitable to possess a firearm.
This was a registry-based observational study. 65,717 persons with dementia registered in the Swedish Dementia Registry were included in the study. Logistic regression was used to evaluate which of the persons' characteristics were most important in predicting the likelihood of being reported as unsuitable to possess a firearm. Relative importance of predictors was quantified using standardized coefficients (SC) and dominance analysis (DA).
Out of 53,384 persons with dementia, 1,823 owned a firearm and 419 were reported to the police as unsuitable owners. Firearm owners were predominantly younger, males, living alone, and without assistance of homecare. The most important predictors of being reported to the police were: living with another person (SC = 0.23), frontotemporal dementia (SC = 0.18), antipsychotics prescription (SC = 0.18), being diagnosed in a memory/cognitive clinic (SC = -0.27), female gender (SC = 0.18), mild (SC = -0.25) and moderate (SC = -0.21) dementia, and hypnotics prescription (SC = 0.17).
Firearm owners with dementia were mostly younger males who were still living more independent lives. The decision to remove a weapon was not solely based on a diagnosis of dementia but a combination of factors was considered.
2017 年，瑞典有 229.6 万支枪支由私人合法持有，有 15 万人患有痴呆症。这些人中的一部分拥有枪支可能会带来安全隐患。
描述瑞典患有痴呆症者的枪支拥有情况，并研究哪些特征可以解释医生决定将某人报告给警方，认为其不适合持有枪支。
这是一项基于登记的观察性研究。共纳入瑞典痴呆症登记处登记的 65717 名痴呆症患者。使用逻辑回归评估哪些患者特征对预测报告为不适合持有枪支的可能性最重要。使用标准化系数（SC）和优势分析（DA）来量化预测因子的相对重要性。
在 53384 名患有痴呆症的患者中，有 1823 人拥有枪支，419 人被报告给警方不适合拥有枪支。枪支拥有者主要是年龄较小、男性、独居且没有家庭护理帮助的人。被报告给警方的最重要预测因素是：与他人同住（SC=0.23）、额颞叶痴呆（SC=0.18）、抗精神病药物处方（SC=0.18）、在记忆/认知诊所诊断（SC=-0.27）、女性（SC=0.18）、轻度（SC=-0.25）和中度（SC=-0.21）痴呆以及催眠药物处方（SC=0.17）。
患有痴呆症的枪支拥有者主要是年龄较小的男性，他们仍然过着更加独立的生活。决定收缴武器不仅仅基于痴呆症的诊断，而是综合考虑了多种因素。
