背景资料：很少有关于心理健康的认知流行病学研究关注病前智力与常见精神障碍（如抑郁症、睡眠困难和心理健康状况）的自我报告之间的联系。目前的研究探讨这些协会在50岁adultes.Methods：该研究使用的数据从5793名参与者在全国青年纵向调查1979年队列（NLSY-79）谁回答了心理健康问题，在50岁时，有智商测量与武装部队资格测试（AFQT），当他们的年龄在15至23岁之间，在1980年。心理健康结果是：抑郁症的终身诊断; 12项简式健康调查（SF-12）的精神成分评分; 7项流行病学研究中心抑郁量表（CES-D）;以及睡眠困难的汇总测量。年轻人的高智商与50岁时自我报告的心理健康问题的风险降低有关，首次访谈时年龄和性别调整后的B值如下：CES-抑郁（B =-0.16，C. I. -0.19至-0.12，p < 0.001）、睡眠困难（B =-0.11，C. I. -0.13至-0.08，p < 0.001）和SF-12精神健康状况（OR = 0.78，C.I. 0.72至0.85，p < 0.001; r = -0.03 p = 0.075）。相反，年轻人的智力与50岁之前接受抑郁症诊断的风险增加有关（OR 1.11，C.I. 1.01 r = 0.03，p = 0.109）。在这些关联中没有观察到性别差异。调整成人SES可以解释智商和心理健康结果之间的大部分关联，除了报告了抑郁症的诊断，在这种情况下，调整成人SES导致正关联的大小增加（OR = 1.32，C.I. 1.16至1.51，p < 0.001）。(C)2016作者爱思唯尔公司出版
Background: Few cognitive epidemiology studies on mental health have focused on the links between pre-morbid intelligence and self-reports of common mental disorders, such as depression, sleep difficulties, and mental health status. The current study examines these associations in 50-year-old adults.Methods: The study uses data from the 5793 participants in the National Longitudinal Survey of Youth 1979 cohort (NLSY-79) who responded to questions on mental health at age 50 and had IQ measured with the Armed Forces Qualification Test (AFQT) when they were aged between 15 and 23 years in 1980. Mental health outcomes were: life-time diagnosis of depression; the mental component score of the 12-item short-form Health Survey (SF-12); the 7-item Center for Epidemiological Studies Depression Scale (CES-D); and a summary measure of sleep difficulty.Results & conclusion: Higher intelligence in youth is associated with a reduced risk of self-reported mental health problems at age 50, with age-at-first-interview and sex adjusted Bs as follows: CES-depression (B = -0.16, C. I. -0.19 to -0.12, p < 0.001), sleep difficulties (B = -0.11, C.I. -0.13 to -0.08, p < 0.001), and SF-12 mental health status (OR = 0.78, C.I. 0.72 to 0.85, p < 0.001; r = -0.03 p = 0.075). Conversely, intelligence in youth is linked with an increased risk of receiving a diagnosis of depression by the age of 50 (OR 1.11, C.I. 1.01 to 1.22, p = 0.024; r = 0.03, p = 0.109). No sex differences were observed in the associations. Adjusting for adult SES accounted for most of the association between IQ and the mental health outcomes, except for having reported a diagnosis of depression, in which case adjusting for adult SES led to an increase in the size of the positive association (OR = 1.32, C.I. 1.16 to 1.51, p < 0.001).
