Intelligence is a life-long trait that exerts powerful influences on educational success, occupational status, use of health services, life style and recreational choices. Until recently, the influence of cognitive performance on time to death was thought largely to be based on failing cognition in the time immediately before death or because lower mental ability was associated with low socioeconomic status and socioeconomic disadvantage. Children who were systematically IQ tested early in the twentieth century have now completed most of their life expectancy and permit evaluation of a possible link between childhood IQ and survival. This link is discussed as it affects people with intellectual disability and as a possible contributor to the acquisition of a healthy life style or use of health services. Studies on the topic are affected by many methodological pitfalls. Recently, as cohorts IQ tested as adolescents have completed middle age, new relevant data have become available. These suggest that earlier attempts to tease out the confounding effects of socioeconomic status on the relationship between childhood IQ and mortality did not take account of the full effects of childhood adversity on IQ and disease risk. When statistical models that include childhood adversity are tested, these attenuate and sometimes remove the contribution of IQ to morbidity and premature death.

儿童智力 (IQ)、成人发病率和死亡率之间的关联

智力是一种终生的特征，它对教育成功、职业地位、医疗服务的使用、生活方式和娱乐选择产生强大的影响。直到最近，认知能力对死亡时间的影响主要被认为是基于死亡前的认知能力下降，或者因为较低的心智能力与较低的社会经济地位和社会经济劣势有关。在 20 世纪早期接受过系统智商测试的儿童现在已经完成了大部分的预期寿命，并允许评估儿童智商与生存之间可能存在的联系。讨论此链接是因为它会影响智障人士，并可能有助于获得健康的生活方式或使用卫生服务。关于该主题的研究受到许多方法论缺陷的影响。最近，随着青少年在中年时测试智商的队列，新的相关数据已经可用。这些表明，早先试图梳理社会经济地位对儿童智商和死亡率之间关系的混杂影响的尝试并没有考虑到儿童逆境对智商和疾病风险的全部影响。当测试包括童年逆境在内的统计模型时，这些模型会减弱甚至有时会消除智商对发病率和过早死亡的影响。这些表明，早期试图梳理社会经济地位对儿童智商和死亡率之间关系的混杂影响并没有考虑到儿童逆境对智商和疾病风险的全部影响。当测试包括童年逆境在内的统计模型时，这些模型会减弱甚至有时会消除智商对发病率和过早死亡的影响。这些表明，早期试图梳理社会经济地位对儿童智商和死亡率之间关系的混杂影响并没有考虑到儿童逆境对智商和疾病风险的全部影响。当测试包括童年逆境在内的统计模型时，这些模型会减弱甚至有时会消除智商对发病率和过早死亡的影响。
