Abstract

Purpose: This study aimed to examine longitudinal associations of workplace effort and reward with changes in cognitive function among United States workers.

Methods: Data from the national, population-based Midlife in the United States (MIDUS) study with a 9-year follow-up were used. Validated workplace effort and reward scales were measured at baseline, and cognitive outcomes (including composite cognition, episodic memory, and executive functioning) were measured with the Brief Test of Adult Cognition by Telephone (BTACT) at baseline and follow-up. Multivariable linear regression analyses based on generalized estimating equations (GEE) examined the longitudinal associations under study.

Results: Among this worker sample of 1,399, after accounting for demographics, socioeconomics, lifestyle behaviors, health conditions, and job control, high reward at baseline was associated with increased composite cognition (regression coefficient: 0.118 [95% CI: 0.049, 0.187]), episodic memory (0.106 [0.024, 0.188]), and executive functioning (0.123 [0.055, 0.191]) during follow-up. The joint exposure of 'high effort and high reward' was also associated with increased composite cognition (0.130 [0.030, 0.231]), episodic memory (0.131 [0.012, 0.250]), and executive functioning (0.117 [0.017, 0.216]), while the combination of 'low effort and high reward' was associated with increased composite cognition (0.106 [0.009, 0.204]) and executive functioning (0.139 [0.042, 0.235]).

Conclusion: Findings suggest that workplace high reward is related to improved cognitive scores among United States workers. Future research should investigate larger cohorts over longer timespans and expand into disease outcomes such as dementia. If these findings emerge as causal, relevant workplace rewards to promote worker cognitive health should be considered.

工作中的努力和回报与认知功能变化的纵向关联:来自美国工人全国性研究的证据。
目的:本研究旨在探讨工作场所的努力和奖励与美国工人认知功能变化之间的纵向联系:研究采用了美国中年(MIDUS)全国性人口研究的数据,并进行了为期 9 年的跟踪调查。在基线时测量了经过验证的工作场所努力和奖励量表,在基线和随访时使用电话成人认知简测(BTACT)测量了认知结果(包括综合认知、外显记忆和执行功能)。基于广义估计方程(GEE)的多变量线性回归分析检验了研究中的纵向关联:在 1399 名工人样本中,在考虑了人口统计学、社会经济学、生活方式行为、健康状况和工作控制等因素后,基线时的高回报与随访期间综合认知能力(回归系数:0.118 [95% CI:0.049, 0.187])、外显记忆(0.106 [0.024, 0.188])和执行功能(0.123 [0.055, 0.191])的提高有关。高努力和高回报 "的共同暴露也与综合认知(0.130 [0.030, 0.231])、外显记忆(0.131 [0.012, 0.250])和执行功能(0.117 [0.017, 0.216])的增加有关,而 "低努力和高回报 "的组合与综合认知(0.106 [0.009, 0.204])和执行功能(0.139 [0.042, 0.235])的增加有关:研究结果表明,工作场所的高回报与美国工人认知分数的提高有关。未来的研究应在更长的时间跨度内对更大的群体进行调查,并扩展到痴呆症等疾病结果。如果这些研究结果显示出因果关系,则应考虑通过相关的工作场所奖励来促进工人的认知健康。

期刊介绍: International Archives of Occupational and Environmental Health publishes Editorials, Review Articles, Original Articles, and Letters to the Editor. It welcomes any manuscripts dealing with occupational or ambient environmental problems, with a special interest in research at the interface of occupational health and clinical medicine. The scope ranges from Biological Monitoring to Dermatology, from Fibers and Dust to Human Toxicology, from Nanomaterials and Ultra-fine Dust to Night- and Shift Work, from Psycho-mental Distress and Burnout to Vibrations. A complete list of topics can be found on the right-hand side under For authors and editors. In addition, all papers should be based on present-day standards and relate to: -Clinical and epidemiological studies on morbidity and mortality -Clinical epidemiological studies on the parameters relevant to the estimation of health risks -Human experimental studies on environmental health effects. Animal experiments are only acceptable if relevant to pathogenic aspects. -Methods for studying the topics mentioned above.
