Abstract

Background: Personality has been implicated in stroke death. However, the role of personality in stroke incidence is unclear.

Purpose: Our primary aim was to investigate associations between optimism, determination, control, and the "Big Five" personality traits on incident stroke. A secondary aim was to assess the potential mediating role of health behaviors in the personality-stroke relationship.

Methods: A total of 3,703 stroke-free participants from the English Longitudinal Study of Ageing provided data on personality using the Midlife Development Inventory at Wave 5 (2010/11). Self-reported incident stroke was assessed from Waves 6 to 8 (2012-2017). Associations were modeled using discrete-time survival proportional odds logistic models. Analyses were adjusted for sociodemographic factors, history of other cardiometabolic diseases, and health behaviors.

Results: Over 6 years follow-up there were 125 incident strokes. Higher optimism (hazard ratio [HR] = 0.66; 95% confidence interval [CI] 0.53, 0.82), openness (HR = 0.72; 95% CI 0.53, 0.98), and conscientiousness (HR = 0.59; 95% CI 0.42, 0.84) were associated with reduced incident stroke risk in unadjusted models. After adjustment for sociodemographic factors and history of cardiometabolic disease, only the association between optimism and incident stroke remained significant (HR = 0.72; 95% CI 0.57, 0.92). The effect of optimism remained significant in a final model adjusting for health behaviors (HR = 0.75; 95% CI 0.60, 0.96). There was evidence of a small but significant mediating effect of physical activity.

Conclusions: Higher trait optimism was associated with reduced stroke risk. This association was partially mediated by physical activity albeit the effect was small, and caution warranted inferring causality. The interplay of personality, behavior, and clinical risk factors in stroke incidence and survivorship needs further investigation.

中风幸存者的乐观情绪与中风发病率之间的关系：英国老龄化纵向研究的发现

背景：人格与中风死亡有关。目的：我们的主要目的是研究乐观、果断、控制和 "大五 "人格特质与中风事件之间的关系。次要目的是评估健康行为在人格与中风关系中的潜在中介作用：方法：英国老龄化纵向研究（English Longitudinal Study of Ageing）的第 5 波（2010/11 年）中，共有 3703 名未发生中风的参与者使用中年发展量表（Midlife Development Inventory）提供了有关人格的数据。第 6 波至第 8 波（2012-2017 年）对自我报告的中风事件进行了评估。相关性采用离散时间生存比例几率逻辑模型进行建模。分析对社会人口因素、其他心脏代谢疾病史和健康行为进行了调整：结果：在 6 年的随访中，共发生了 125 例脑卒中。在未经调整的模型中，较高的乐观度（危险比 [HR] = 0.66；95% 置信区间 [CI] 0.53，0.82）、开放性（HR = 0.72；95% CI 0.53，0.98）和自觉性（HR = 0.59；95% CI 0.42，0.84）与中风风险的降低有关。在对社会人口因素和心脏代谢疾病史进行调整后，只有乐观与中风事件之间的关系仍然显著（HR = 0.72; 95% CI 0.57, 0.92）。在调整健康行为的最终模型中，乐观的影响仍然显著（HR = 0.75; 95% CI 0.60, 0.96）。有证据表明，体育锻炼具有微小但显著的中介效应：结论：特质乐观程度越高，中风风险越低。结论：较高的特质乐观与中风风险的降低有关，尽管影响较小，但体育锻炼对这种关联有部分中介作用，因此在推断因果关系时应谨慎。需要进一步研究人格、行为和临床风险因素在中风发病率和存活率中的相互作用。

期刊介绍： Annals of Behavioral Medicine aims to foster the exchange of knowledge derived from the disciplines involved in the field of behavioral medicine, and the integration of biological, psychosocial, and behavioral factors and principles as they relate to such areas as health promotion, disease prevention, risk factor modification, disease progression, adjustment and adaptation to physical disorders, and rehabilitation. To achieve these goals, much of the journal is devoted to the publication of original empirical articles including reports of randomized controlled trials, observational studies, or other basic and clinical investigations. Integrative reviews of the evidence for the application of behavioral interventions in health care will also be provided. .
