Objective. We aim to investigate whether centenarians are significantly more resilient than younger elders and whether resilience significantly contributes to exceptional longevity. Data. We use a unique dataset from the Chinese Longitudinal Healthy Longevity Survey with the largest sample to date of centenarians, nonagenarians, octogenarians, and a compatible group of young old aged 65-79. Methods and Results. Logistic regressions based on the cross-sectional sample show that after controlling for various confounders, including physical health and cognitive status, centenarians are significantly more resilient than any other old-age group. Logistic regression analyses based on the longitudinal data show that nonagenarians aged 94-98 with better resilience have a 43.1% higher likelihood of becoming a centenarian compared to nonagenarians with lower resilience. Conclusions. Resilience significantly contributes to longevity at all ages, and it becomes even more profound at very advanced ages. These findings indicate that policies and programs to promote resilience would have long-term and positive effects on the well-being and longevity for senior citizens and their families.
目的。我们旨在调查百岁老人是否比年轻老年人更具恢复力,以及恢复力是否对超长寿命有显著贡献。数据。我们使用了来自中国健康与养老追踪调查的独特数据集,该数据集拥有迄今为止最大规模的百岁老人、九旬老人、八旬老人样本,以及一组年龄在65 - 79岁的年轻老年人作为对照样本。方法与结果。基于横断面样本的逻辑回归分析表明,在控制了包括身体健康和认知状况等各种混杂因素后,百岁老人比其他任何老年群体都更具恢复力。基于纵向数据的逻辑回归分析表明,恢复力较强的94 - 98岁九旬老人成为百岁老人的可能性比恢复力较弱的九旬老人高出43.1%。结论。恢复力在所有年龄段都对长寿有显著贡献,在极高龄时这种作用更为显著。这些发现表明,促进恢复力的政策和项目将对老年人及其家庭的幸福和长寿产生长期积极影响。
