本研究确定了晚年认知功能轨迹的差异模式，并研究了生命历程因素和社会参与与群体轨迹的相关程度。数据来自健康和退休研究的七波（HRS 1998-2010; n = 7374;观察= 41，051）。潜在类别增长分析确定了认知功能轨迹组，并使用多项logistic回归来检查与组轨迹相关的因素。确定了五种异质性轨迹：稳定高、稳定中等、稳定低、高到中等和中等到低。研究结果表明，在调整生命历程因素后，成为志愿者的人更有可能属于两个最不脆弱的轨迹之一，稳定的高或高到中等。我们的研究结果表明，尽管累积的生命过程中的因素明显的认知能力下降，社会参与在老年可能作为一个潜在的保护资源。
This study identified differential patterns of later-life cognitive function trajectories and examined to what extent life course factors and social engagement are associated with group trajectories. Data came from seven waves of the Health and Retirement Study (HRS 1998–2010; n = 7374; Observations = 41,051). Latent class growth analysis identified cognitive function trajectory groups, and multinomial logistic regression was used to examine the factors associated with group trajectories. Five heterogeneous trajectories were identified: stable high, stable moderate, stable low, high-to-moderate, and moderate-to-low. Findings suggest that, after adjusting for life course factors, individuals who became volunteers were more likely to belong to one of the two least vulnerable trajectories, stable high or high-to-moderate. Our findings suggest that, despite the cumulative life course factors evident in cognitive decline, social engagement in old age may serve as a potential protective resource.
