Abstract

Abstract. Prolonged elevation of cortisol, the primary stress biomarker, is associated with impaired cognitive and physical health. Cortisol tends to increase in later life among most, but not all, older individuals. The current study considered whether this pattern could be explained by more-positive age stereotypes acting as a stress buffer. The 439 participants drawn from the Baltimore Longitudinal Study of Aging provided 1,789 cortisol measurements, from 24-h collections of urine, across 30 years. Among those aged 50 or greater, the cortisol of the more-negative age-stereotype group increased by 44%, whereas the more-positive age-stereotype group showed no increase. Also as expected, there was no association of age stereotypes and cortisol level among the younger participants, for whom the age stereotypes were self-irrelevant. The findings indicate the importance of considering the relationship between both positive and negative stereotypes and stress biomarkers over time.

积极的年龄自我刻板印象预测30年内较低的皮质醇
摘要皮质醇(主要的压力生物标志物)的长期升高与认知和身体健康受损有关。在大多数(但不是全部)老年人中,皮质醇倾向于在晚年增加。目前的研究考虑了这种模式是否可以用更积极的年龄刻板印象作为压力缓冲来解释。来自巴尔的摩老龄化纵向研究的439名参与者提供了1,789个皮质醇测量值,这些测量值来自30年来24小时的尿液收集。在50岁及以上的人群中,年龄刻板印象较消极组的皮质醇增加了44%,而年龄刻板印象较积极组的皮质醇则没有增加。同样,正如预期的那样,年龄刻板印象和皮质醇水平在年轻参与者中没有关联,对他们来说,年龄刻板印象是自我无关的。研究结果表明,随着时间的推移,考虑积极和消极刻板印象与压力生物标志物之间的关系是很重要的。
