目的：本研究旨在确定人口的影响，严重精神疾病患者暴力criminal.Method：瑞典拥有高质量的国家登记所有入院和刑事定罪。将所有出院的ICD诊断为精神分裂症和其他精神病的患者（N= 98，082）与犯罪登记册联系起来，以确定严重精神疾病患者与暴力犯罪的人群归因风险。根据性别、三个年龄段（15-24岁、25-39岁和40岁及以上）和犯罪类型计算归因风险。结果：在13年的时间里，每1,000名居民中有45起暴力犯罪。其中2.4宗是由严重精神病患者所引致。这相当于5.2%的人群归因风险分数。在所有年龄段中，女性的可归因风险分数均高于男性。在25-39岁的妇女中，这一比例为14.0%，在40岁以上的妇女中，这一比例为19.0%。归因风险分数最低的年龄在15-24岁（男性患者为2.3%，女性患者为2.9%）。结论：严重精神疾病患者对暴力犯罪的人口影响，通过计算人口归因风险估计，因性别和年龄而异。总体而言，患者的人口归因风险分数为5%，这表明严重精神疾病患者每20起暴力犯罪中就有1起。
Objective: This study aimed to determine the population impact of patients with severe mental illness on violent crime.Method: Sweden possesses high-quality national registers for all hospital admissions and criminal convictions. All individuals discharged from the hospital with ICD diagnoses of schizophrenia and other psychoses (N=98,082) were linked to the crime register to determine the populationattributable risk of patients with severe mental illness to violent crime. The attributable risk was calculated by gender, three age bands (15-24, 25-39, and 40 years and over), and offense type.Results: Over a 13-year period, there were 45 violent crimes committed per 1,000 inhabitants. Of these, 2.4 were attributable to patients with severe mental illness. This corresponds to a population-attributable risk fraction of 5.2%. This attributable risk fraction was higher in women than men across all age bands. In women ages 25-39, it was 14.0%, and in women over 40, it was 19.0%. The attributable risk fractions were lowest in those ages 15-24 (2.3% for male patients and 2.9% for female patients).Conclusions: The population impact of patients with severe mental illness on violent crime, estimated by calculating the population-attributable risk, varies by gender and age. Overall, the population-attributable risk fraction of patients was 5%, suggesting that patients with severe mental illness commit one in 20 violent crimes.
