步行速度是老年人身体功能的一个有意义的标志。虽然这主要是一种物理测量，但实验研究表明，仅仅用对衰老的负面刻板印象来引导老年人，就会导致客观步行速度立即下降。目前尚不清楚的是，这是否是一个暂时的实验效果，或者消极的老龄化刻板印象是否对长期客观的健康产生有害影响。我们试图探索一般人群对衰老的基线负面看法与2年后的客观步行速度之间的关联。在爱尔兰老龄化纵向研究（TILDA）的两个阶段对4，803名参与者进行了评估，TILDA是一项针对爱尔兰共和国50岁以上成年人的前瞻性人口代表性研究。第一波测量-包括衰老感知问卷，步行速度和所有协变量-在2009年至2011年期间进行。第2波测量-包括步行速度和协变量的第二次测量-在2012年3月至12月之间收集2年后。步行速度被测量为完成定时起立行走（TUG）任务的秒数。排除有中风史、帕金森病或MMSE < 18的患者。在对所有协变量（年龄、性别、教育水平、残疾、慢性病、药物、整体认知和基线TUG）进行全面调整后，基线时对衰老的负面看法与2年后TUG速度较慢相关（B= 0.03，95% CI = 0.01至0.05，p<0.05）。步行速度以前被认为是身体衰退的结果，但这些结果突出了心理状态在预测客观衰老结果中的直接作用。对衰老的负面看法是衰老中身体衰退的某些因素的潜在可改变的风险因素。
Walking speed is a meaningful marker of physical function in the aging population. While it is a primarily physical measure, experimental studies have shown that merely priming older adults with negative stereotypes about aging results in immediate declines in objective walking speed. What is not clear is whether this is a temporary experimental effect or whether negative aging stereotypes have detrimental effects on long term objective health. We sought to explore the association between baseline negative perceptions of aging in the general population and objective walking speed 2 years later. 4,803 participations were assessed over 2 waves of The Irish Longitudinal Study on Ageing (TILDA), a prospective, population representative study of adults aged 50+ in the Republic of Ireland. Wave 1 measures – which included the Aging Perceptions Questionnaire, walking speed and all covariates - were taken between 2009 and 2011. Wave 2 measures – which included a second measurement of walking speed and covariates - were collected 2 years later between March and December 2012. Walking speed was measured as the number of seconds to complete the Timed Up-And-Go (TUG) task. Participations with a history of stroke, Parkinson’s disease or an MMSE < 18 were excluded. After full adjustment for all covariates (age, gender, level of education, disability, chronic conditions, medications, global cognition and baseline TUG) negative perceptions of aging at baseline were associated with slower TUG speed 2 years later (B=.03, 95% CI = .01 to 05, p< .05). Walking speed has previously been considered to be a consequence of physical decline but these results highlight the direct role of psychological state in predicting an objective aging outcome. Negative perceptions about aging are a potentially modifiable risk factor of some elements of physical decline in aging.
