目的探讨男性18岁时智力测验得分与随后自杀的关系。瑞典兵役征召登记册（1968- 1994）与多代登记册、死亡原因登记册和人口普查数据的设计记录联系研究。进行了四项试验。在征兵中，包括逻辑、语言、空间和技术技能。设置瑞典。参与者987 308名瑞典男性随访5-26年。主要结局指标：自杀。结果随访期间发生自杀事件2811例。得分最低的学生自杀的风险是得分最高的学生的两到三倍。在逻辑测试中发现了最强的关联：测试分数每增加一个单位，自杀的风险就会下降12%（95%置信区间为10%到14%）。当我们控制父母的社会经济地位时，这种联系只是稍微减弱。在受过良好教育的父母的后代中，表现不佳的风险最大。结论：男性智力测验成绩与随后的自杀风险密切相关。这可能是由于认知能力在严重精神障碍的病因学或个人在经历急性生活危机或患有精神疾病时解决问题的能力方面的重要性。
Objective To examine the association between intelligence test scores in men, measured at age 18, and subsequent suicide.Design Record linkage study of the Swedish military service conscription register (1968-94) with the multi-generation register, cause of death register, and census data. Four tests were performed. at conscription covering logic, language, spatial, and technical skills.Setting Sweden.Participants 987 308 Swedish men followed up for 5-26 years.Main outcome measure Suicide.Results 2811 Suicides occurred during follow up. The risk of suicide was two to three times higher in those with lowest compared with the highest test scores. The strongest associations were seen with the logic test: for each unit increase in test score the risk of suicide decreased by 12% (95% confidence interval 10% to 14%). Associations were only slightly attenuated when we controlled for parents' socioeconomic position. Greatest risks were seen among poorly performing offspring of well educated parents.Conclusions Performance in intelligence tests is strongly related to subsequent risk of suicide in men. This may be due to the importance of cognitive ability in either the aetiology of serious mental disorder or an individual's capacity to solve problems while going through an acute life crisis or suffering from mental illness.
