OBJECTIVES
Numerous studies have documented the relationship between education and cognitive functioning at the individual level. Yet few studies have examined whether a spouse's education spills over to influence the other spouse's cognitive functioning. This study, therefore, investigates the association between spousal education and cognitive functioning, the pathways that may account for this association, and gender differences in this association.
METHOD
Growth curve models were analyzed by using longitudinal couple data from the Health and Retirement Study (N = 5,846 individuals).
RESULTS
More years of spousal education are associated with higher level of cognitive functioning at age 65 (γ000 = 0.0532, 95% confidence interval [CI] = 0.0163-0.0901) and slower decline in cognitive functioning in later adulthood (γ100 = 0.0054, 95% CI = 0.0026-0.0082). The positive association between spousal education and the level of cognitive functioning at age 65 is fully explained by economic resources. The association of spousal education with the rate of change in cognitive functioning decreases but remains significant after controlling for economic resources and health behaviors (γ100 = 0.0043, 95% CI = 0.0014-0.0072). The association between spousal education and cognitive functioning is similar for men and women.
DISCUSSION
Findings suggest that more years of spousal education may slow decline in cognitive functioning for men and women in later life.
目的
许多研究都记录了个体受教育程度与认知功能之间的关系。然而，很少有研究探讨配偶的教育程度是否会溢出，影响另一方的认知功能。因此，本研究调查了配偶教育程度与认知功能之间的关系、可能解释这种关系的途径，以及这种关系在性别上的差异。
方法
利用健康与退休研究（Health and Retirement Study）的纵向夫妻数据（N=5846 人），采用增长曲线模型进行分析。
结果
配偶受教育年限增加与 65 岁时认知功能水平较高（γ000=0.0532，95%置信区间[CI]为 0.0163-0.0901）和成年后期认知功能下降速度较慢（γ100=0.0054，95%CI 为 0.0026-0.0082）相关。配偶教育程度与 65 岁时认知功能水平之间的正相关完全可以用经济资源来解释。在控制经济资源和健康行为后，配偶教育程度与认知功能变化率之间的关联虽然有所减弱，但仍然显著（γ100=0.0043，95%CI 为 0.0014-0.0072）。配偶教育程度与认知功能之间的关联在男性和女性中相似。
讨论
研究结果表明，配偶受教育年限的增加可能会减缓男性和女性晚年认知功能的下降。
