BACKGROUND Psychological resilience refers to an individual's ability to cope with and adapt to challenging life circumstances and events. OBJECTIVE This study aims to explore the association between psychological resilience and all-cause mortality in a national cohort of US older adults by a cross-sectional study. METHODS The Health and Retirement Study (2006-2008) included 10 569 participants aged ≥50. Mortality outcomes were determined using records up to May 2021. Multivariable Cox proportional hazards models were used to analyse the associations between psychological resilience and all-cause mortality. Restricted cubic splines were applied to examine the association between psychological resilience and mortality risk. FINDINGS During the follow-up period, 3489 all-cause deaths were recorded. The analysis revealed an almost linear association between psychological resilience and mortality risk. Higher levels of psychological resilience were associated with a reduced risk of all-cause mortality in models adjusting for attained age, sex, race and body mass index (HR=0.750 per 1 SD increase in psychological resilience; 95% CI 0.726, 0.775). This association remained statistically significant after further adjustment for self-reported diabetes, heart disease, stroke, cancer and hypertension (HR=0.786; 95% CI 0.760, 0.813). The relationship persisted even after accounting for smoking and other health-related behaviours (HR=0.813; 95% CI 0.802, 0.860). CONCLUSIONS This cohort study highlights the association between psychological resilience and all-cause mortality in older adults in the USA. CLINICAL IMPLICATIONS Psychological resilience emerges as a protective factor against mortality, emphasising its importance in maintaining health and well-being.

健康与退休研究中心理弹性与全因死亡率之间的关联。


背景技术心理弹性是指个体应对和适应具有挑战性的生活环境和事件的能力。目的 本研究旨在通过横断面研究探讨美国老年人全国队列中心理弹性与全因死亡率之间的关联。方法 健康与退休研究（2006-2008）包括 10 569 名年龄≥50 岁的参与者。使用截至 2021 年 5 月的记录确定死亡率结果。使用多变量 Cox 比例风险模型来分析心理弹性与全因死亡率之间的关联。应用受限三次样条来检查心理弹性与死亡风险之间的关联。结果 在随访期间，记录了 3489 例全因死亡。分析显示，心理弹性与死亡风险之间几乎呈线性相关。在调整年龄、性别、种族和体重指数的模型中，较高水平的心理复原力与全因死亡率风险降低相关（心理复原力每增加 1 个 SD，HR = 0.750；95% CI 0.726，0.775）。在进一步调整自我报告的糖尿病、心脏病、中风、癌症和高血压后，这种关联仍然具有统计学意义（HR=0.786；95% CI 0.760，0.813）。即使考虑到吸烟和其他健康相关行为，这种关系仍然存在（HR=0.813；95% CI 0.802，0.860）。结论 这项队列研究强调了美国老年人心理弹性与全因死亡率之间的关联。临床意义 心理复原力作为预防死亡的保护因素而出现，强调了其在维持健康和福祉方面的重要性。
