Abstract

Objective

To explore the associations of Physical Activity (PA) and sleep with functional disability among older adults.

Method

A total of 1927 participants were enrolled from the China Health and Retirement Longitudinal Study (CHARLS) between 2015 and 2020. Activities of Daily Living (ADL) were used to assess functional status. Sleep consisted of nighttime sleep (healthy sleep, or unhealthy sleep) and daytime nap sleeping (extended, moderate, short, or none), and PA was classified as sufficient or insufficient. Effects of sleep and PA on ADL Disability (ADLD) among the elderly were examined using logistic regression analysis, with Odds Ratios (ORs) and 95% Confidence Intervals (95% CIs) calculated.

Results

After a follow-up of 5-years, healthy nighttime sleep was linked to a decreased odds of ADLD (OR = 0.77, 95% CI: 0.60‒0.98). In participants with sufficient PA, healthy nighttime sleep was linked to the odds of ADLD (OR = 0.68, 95% CI: 0.52‒0.90). No multiplicative interaction of PA and nighttime sleeping was found. Moreover, the association between healthy nighttime sleep and decreased risk of ADLD was consistent in females (OR = 0.64, 95% CI: 0.45‒0.91) and those with complications (OR = 0.63, 95%CI: 0.46‒0.87).

Conclusion

Healthy nighttime sleep may be beneficial for preventing ADLD in older people. The benefits of sufficient PA with healthy sleep on reducing the risk of ADLD remain uncertain.

中国老年人体力活动、睡眠与功能障碍的关系：一项为期五年的前瞻性研究

目的探讨老年人体力活动（PA）和睡眠与功能障碍的关系。方法：从2015 - 2020年中国健康与退休纵向研究（CHARLS）中招募了1927名参与者。日常生活活动（ADL）评估功能状态。睡眠包括夜间睡眠（健康睡眠或不健康睡眠）和白天小睡睡眠（延长、中等、短暂或无），PA分为充足或不足。采用logistic回归分析检验睡眠和PA对老年人ADL残疾（ADLD）的影响，计算比值比（ORs）和95%置信区间（95% ci）。结果经过5年的随访，健康的夜间睡眠与降低ADLD的几率有关（OR = 0.77, 95% CI: 0.60-0.98）。在PA充足的参与者中，健康的夜间睡眠与ADLD的几率有关（OR = 0.68, 95% CI: 0.52-0.90）。没有发现PA与夜间睡眠的乘法相互作用。此外，健康的夜间睡眠与降低ADLD风险之间的关联在女性（OR = 0.64, 95%CI: 0.45-0.91）和并发症患者（OR = 0.63, 95%CI: 0.46-0.87）中是一致的。结论健康的夜间睡眠有助于预防老年人ADLD的发生。充足的PA与健康睡眠对降低ADLD风险的益处仍不确定。
