Our study investigated the association of aggression and suicidal behavior in schizophrenic inpatients. Eight thousand nine hundred one admissions for schizophrenia (1998-2007) to a psychiatric university hospital were included. Schizophrenic suicides (n = 7)/suicide attempters (n = 40) were compared to suicides (n = 30)/suicide attempters (n = 186) with other diagnoses and to schizophrenic non-attempters regarding aggression. Logistic regression analysis was performed to explore risk factors for attempted suicide. Schizophrenic suicides/suicide attempters did not differ from other suicides/suicide attempters or from schizophrenic non-attempters with regard to aggression. Risk of inpatient suicide attempt was increased for patients with attempted suicide at admission, high school graduation, and disorganized subtype. Aggression could not be found to be a predictor of attempted suicide. Aggression seems to have a minor role for suicidal behavior in schizophrenia.
我们的研究调查了精神分裂症住院患者的攻击行为和自杀行为之间的关联。研究纳入了一家精神病大学医院 1998 年至 2007 年间收治的 8911 例精神分裂症患者。将精神分裂症自杀者（n=7/自杀未遂者（n=40）与其他诊断的自杀者（n=30/自杀未遂者（n=186）以及精神分裂症非未遂者进行了比较，以评估攻击行为。采用 logistic 回归分析探讨自杀未遂的危险因素。精神分裂症自杀者/自杀未遂者与其他自杀者/自杀未遂者或与精神分裂症非未遂者相比，在攻击行为方面没有差异。入院时自杀未遂、高中毕业和精神分裂症瓦解型的住院自杀未遂风险增加。攻击性不能预测自杀未遂。在精神分裂症中，攻击性似乎对自杀行为的影响较小。
