Abstract

Objectives: Prior research indicated that diverse work experiences in early and middle life stages are associated with cognitive function in later life. However, whether life course patterns of work history are associated with later life cognitive function in China remains unknown.

Methods: Data were derived from the China Health and Retirement Longitudinal Study, and 5,800 participants aged 60 years or older were included. We used sequence analysis to identify the work history patterns between ages 18 and 60. Growth curve modeling was performed to evaluate how the work-history patterns are associated with global and domain-specific (i.e., mental intactness and episodic memory) cognitive function.

Results: We identified 8 work patterns, distinguished by duration, transitions, timing, and sequence of work history. Compared with individuals exposed to lifelong agricultural work, those engaged in lifelong nonagricultural employed work had better cognitive function in later life and experienced slower rates of cognitive decline in both global cognitive function and the mental intactness domain. In addition, individuals who shifted from agricultural to nonagricultural employed work early (around age 30) had better global cognitive function in later life, whereas the association was not significant for such a transition later (around age 50).

Discussion: Our study highlights the importance of the duration, sequence, and timing of transitions in work history for cognitive health among older Chinese. Future interventions and policies aimed at improving cognitive function should fully consider the cumulative and dynamic nature of work from a life course perspective.

居住在社区的老年人工作史和认知轨迹的生命历程模式。

研究目的先前的研究表明，人生早期和中期的不同工作经历与晚年的认知功能有关。然而，在中国，生命历程中的工作经历模式是否与晚年认知功能相关仍是未知数：数据来源于中国健康与退休纵向研究，共纳入 5800 名 60 岁及以上的参与者。我们使用序列分析来确定 18 岁至 60 岁之间的工作史模式。我们建立了成长曲线模型，以评估工作史模式与整体和特定领域（即精神完好性和外显记忆）认知功能之间的关系：结果：我们确定了八种工作模式，这些模式根据工作历史的持续时间、过渡、时间和顺序来区分。与终生从事农业工作的人相比，终生从事非农业就业工作的人在晚年的认知功能更好，在整体认知功能和精神完好性领域的认知功能下降速度更慢。此外，早期（30 岁左右）从农业工作转向非农业就业工作的人，晚年的总体认知功能较好，而晚期（50 岁左右）从农业工作转向非农业就业工作的人，这种关联并不显著：讨论：我们的研究强调了工作经历转换的持续时间、顺序和时机对中国老年人认知健康的重要性。未来旨在改善认知功能的干预措施和政策应从生命历程的角度充分考虑工作的累积性和动态性。
