In the largest study of its kind researchers have found a link between IQ scores and attempted suicide in men. The study was published this week in the British Medical Journal.
研究人员在一项调查研究中发现，人类智商高低和自杀倾向之间存在联系。这次调查研究在该领域是规模最大的一次， 研究报告发表在了本周出版的《英国医学杂志》之上。
The team analyzed medical records of over one million men dating back nearly a quarter century. Of the one million, nearly 18,000 were admitted at least once for attempted suicide. After adjusting for age and socioeconomic status the scientists found that men with low IQ were increasingly more likely to be suicidal than those with higher IQ scores.
研究团队分析了近25年来超过百万人的医疗档案， 在这一百多万人中，有大约18，000人承认自己至少尝试过一次自杀。 在排除了年龄和社会经济这些因素的影响之后，研究人员们发现，那些智商较低的人群更有可能去尝试自杀。
Researchers suggest that the association of an unhealthy lifestyle (i.e., binge drinking) with lower IQ may influence suicidal ideation. But they also point to other studies that link lower IQ with poor problem-solving ability and this in turn can impact one’s resilience to stress in crisis situations. Another factor may be exposure to violence during childhood. Violence, either experienced directly or merely witnessed, has been shown to have a negative impact on IQ, as well as future suicide risk.
研究人员称，低智商人群不健康的生活方式（也就是酗酒之类的）可能造成了他们与高自杀率之间的联系。 研究人员同时指出，其他一些研究发现，低智商人群因其解决问题能力的欠缺，会造成他们在危急情况下无法有效抗压。 另一个因素可能是这部分人在孩童时期所遭遇的暴力， 这里所说的暴力，不仅包括亲身经历的也同时包括亲眼目睹的，对人的智商发育和未来自杀倾向都有消极影响。
One caveat: This study is based on medical records of Swedish men between 16 and 57 years, so the results cannot be attributed to other cultures, women or even other age groups.
说明： 这项研究的结论是基于瑞典16岁至57岁男性人群的医疗记录，因此研究结果并不一定适用于其它文化、性别或是年龄段的人群。
