目的：本研究对美国老年人进行了为期12年的观察，探讨了生命历程中社会经济地位（SES）与认知功能之间的关系。研究了成人社会经济地位对儿童社会经济地位与认知关系的中介作用，以及累积社会经济地位与认知的关系。方法：采用健康与退休研究中具有全国代表性的样本，采用生长曲线模型对1998 - 2010年的认知状况和认知变化进行了检验。结果：认知功能在人体内和人与人之间存在差异。儿童期社会经济地位不利与基线认知功能低下有关。成人社会地位介导儿童社会地位与认知功能的关系。累积社会经济地位较高的人在认知功能上表现出优势。讨论：童年SES和成年SES都与认知状态有关，并且在较小程度上与以后生活中的认知变化有关。
Objective: This study investigated the relationship between life course socioeconomic status (SES) and cognitive function among older adults in the United States over a 12-year observation period. The mediation of adult SES on the association between childhood SES and cognition was examined, along with the relationship between cumulative SES and cognition. Method: Using a nationally representative sample from the Health and Retirement Study, cognitive status and change in cognition from 1998 to 2010 were examined using growth curve models. Results: The results showed that cognitive function varied within-persons and between-persons. SES disadvantage in childhood was associated with lower cognitive function at baseline. Adult SES mediated the relationship between childhood SES and cognitive function. Persons with higher cumulative SES demonstrated an advantage in cognitive function. Discussion: Childhood SES and adult SES both had relationships with cognitive status and, to a lesser degree, change in cognition in later life.
