Abstract

Background

Sarcopenia is an aging-related disorder characterized by a loss of muscle mass and function. Calf circumference (CC) is a useful surrogate marker of muscle mass and function. This prospective study was designed to investigate the association between CC and all-cause mortality during a follow-up for 5 years in the Chinese centenarians.

Methods

The China Hainan Centenarian Cohort Study (CHCCS) is conducted in 18 cities and counties of Hainan, China.

Results

All 231 centenarians had a mean age of 103.03 years. Survival participants had a longer CC and were often living alone compared with others (P<0.05 for all). Multivariate Cox regression models showed that CC was negatively associated with all-cause mortality (P < 0.05 for all). Participants with a longer CC had a lower mortality risk compared with others [Exp(β): 0.918; 95%confidence interval: 0.863–0.977]. Participants with a longer CC had a lower mortality risk whether they were males or females and lived with family members or alone.

Conclusion

CC was negatively associated with all-cause mortality and could be an indicator of future mortality among the Chinese centenarians. Further researches should focus on preventing a decline in the CC in order to promote human longevity.

中国百岁老人的小腿围与全因死亡率呈负相关:一项为期 5 年的前瞻性随访研究。
背景:肌肉疏松症是一种与衰老有关的疾病,其特征是肌肉质量和功能下降。小腿围(CC)是肌肉质量和功能的有效替代指标。这项前瞻性研究旨在对中国百岁老人进行为期 5 年的随访,调查 CC 与全因死亡率之间的关系:中国海南百岁老人队列研究(CHCCS)在中国海南的 18 个市县开展:所有 231 名百岁老人的平均年龄为 103.03 岁。结果:231 位百岁老人的平均年龄为 103.03 岁,与其他人相比,存活者的 CC 较长,且多为独居:CC与全因死亡率呈负相关,可作为中国百岁老人未来死亡率的指标。进一步的研究应侧重于防止 CC 下降,以促进人类长寿。
