Adult child socioeconomic status (SES) has been identified as a predictor of older parents' cognitive aging. However, studies have primarily relied on educational attainment as the sole measure of adult child SES. We evaluated the relationship between adult children's financial disadvantage and cognitive outcomes of older parents in the United States.
We used data from U.S. Health and Retirement Study (2000-2014, n = 15,053 respondents ≥51 years with at least 1 adult child). Adult child financial disadvantage was measured with 3 indicators of extremely low income, unemployment, and lack of homeownership. We used linear mixed models to estimate the association between adult child financial disadvantage and the rate of decline in verbal memory scores, controlling for respondents' sociodemographic characteristics.
Having at least 1 adult child (vs no adult children) with extremely low income was found to be associated with lower verbal memory (b = -0.041, 95% confidence interval [CI]: -0.043, -0.039) at baseline. There was a small but significant association with the rate of decline in verbal memory z-scores (b = 0.004, 95% CI: 0.000, 0.008) and some evidence of heterogeneity by parent gender, marital status, and SES.
Offspring financial disadvantage may be influential for older parents' initial level of memory function, although evidence of associations with memory decline was weak. Public policy interventions aimed at improving the economic conditions of adult children may indirectly benefit the cognitive performance of disadvantaged parents in their later life.
成年子女的社会经济地位(SES)已被确定为预测老年父母认知衰老的因素。然而,这些研究主要依赖于教育程度作为衡量成年子女 SES 的唯一指标。我们评估了美国成年子女经济劣势与老年父母认知结果之间的关系。
我们使用了美国健康与退休研究(2000-2014 年,n=15053 名年龄≥51 岁且至少有 1 名成年子女的受访者)的数据。成年子女的经济劣势用 3 个指标来衡量:极低收入、失业和没有住房所有权。我们使用线性混合模型来估计成年子女经济劣势与言语记忆评分下降率之间的关联,同时控制了受访者的社会人口统计学特征。
与没有成年子女(vs.有成年子女)相比,至少有 1 名成年子女(vs.没有成年子女)收入极低与基线时较低的言语记忆相关(b=-0.041,95%置信区间[CI]:-0.043,-0.039)。与言语记忆 z 评分下降率呈微弱但显著的关联(b=0.004,95%CI:0.000,0.008),并且存在父母性别、婚姻状况和 SES 方面的异质性证据。
子女的经济劣势可能对老年父母的初始记忆功能水平有影响,尽管与记忆衰退的关联证据较弱。旨在改善成年子女经济状况的公共政策干预措施可能会间接有益于处于弱势地位的父母在晚年的认知表现。
