Cognitive function may be influenced by education, socioeconomic status, sex, and health status. Furthermore, aging interacts with these factors to influence cognition and dementia risk in late life. Factors that may increase or decrease successful cognitive aging are of critical importance, particularly if they are modifiable. The purpose of this study was to determine if economic status in late life is associated with cognition independent of socioeconomic status in early life. Cross-sectional demographic, socioeconomic, and cognitive function data were obtained in 2592 older adults (average age 71.6 years) from the Center for Disease Control's National Health and Nutrition Examination Survey (NHANES) and analyzed with linear regression modeling. Cognitive function, as measured with a test of processing speed, was significantly associated with poverty index scores after adjusting for educational attainment as an estimate of childhood socioeconomic status, ethnic background, age, health status, and sex (P < 0.001). Our findings suggest that current economic status is independently associated with cognitive function in adults over age 60 years.
认知功能可能受教育程度、社会经济地位、性别和健康状况的影响。此外，衰老与这些因素相互作用，影响晚年的认知和痴呆风险。可能增加或减少成功认知衰老的因素至关重要，特别是如果它们是可改变的。本研究的目的是确定晚年的经济状况是否独立于早年的社会经济地位而与认知相关。从疾病控制中心的国家健康和营养检查调查（NHANES）中获取了2592名老年人（平均年龄71.6岁）的横断面人口统计学、社会经济和认知功能数据，并采用线性回归模型进行分析。在将教育程度作为童年社会经济地位的估计值、种族背景、年龄、健康状况和性别进行调整后，用处理速度测试衡量的认知功能与贫困指数得分显著相关（P < 0.001）。我们的研究结果表明，当前的经济状况与60岁以上成年人的认知功能独立相关。
