Abstract

BACKGROUND

Sleep disorders and physical dysfunction are prevalent in the elderly, particularly among hospitalized individuals, yet the relationship between the two remains unclear. Given China's rapidly aging population, understanding how sleep quality relates to physical function is crucial for informing healthcare practices. This study aims to analyze the relationship between sleep quality and physical function indicators in older patients admitted to internal wards.

METHODS

In this cross-sectional study, the patients admitted in geriatric department were included. Sleep quality was assessed with 8 items Athens Insomnia Scale (AIS-8). Physical function was evaluated from 3 domains: mobility evaluated by Short Physical Performance Battery (SPPB) and gait speed, muscle strength evaluated by grip and chair rises test, balance performance assessed by Timed Up-and-Go test (TUGT). Logistic regression was applied for statistical analyses, adjusting for confounders.

RESULTS

A total of 545 old patients (≥ 60 years) were included. Those with poor sleep quality (AIS-8 ≥ 6) exhibited a higher likelihood of physical dysfunction, the odds ratio (95% confidence interval) was 1.892 (1.037-3.453) for low gait speed, 1.810 (1.110-2.952) for low grip strength, 2.491 (1.496-4.147) for impaired TUGT. Sleep quality components, particularly maintenance and daytime dysfunction, were linked to physical function indicators. Stratified by age, poor sleep quality was associated with a higher incidence of low grip strength and impaired TUGT in participants ≥ 75 years old. But the association wasn't seen in patients < 75 years. Stratified by gender, a significant association of sleep quality with impaired TUGT in female population was observed but not for the male population.

CONCLUSIONS

Poor sleep quality was associated with reduced physical function, especially in with advancing ageand in women. Targeted interventions to enhance sleep in the elderly may contribute to maintaining physical function and improve the quality of life of such patients.

摘要

背景

睡眠障碍和身体功能障碍在老年人中普遍存在，尤其是在住院患者中，但两者之间的关系仍不清楚。鉴于中国人口老龄化迅速，了解睡眠质量与身体功能之间的关系对于指导医疗实践至关重要。本研究旨在分析内科病房老年患者睡眠质量与身体功能指标之间的关系。

方法

在这项横断面研究中，纳入了老年科收治的患者。采用8项雅典失眠量表（AIS-8）评估睡眠质量。从3个领域评估身体功能：通过简短体能测试电池（SPPB）和步速评估 mobility，通过握力和从椅子上起身测试评估肌肉力量，通过定时起立行走测试（TUGT）评估平衡能力。应用逻辑回归进行统计分析，并对混杂因素进行校正。

结果

共纳入545例老年患者（≥60岁）。睡眠质量差（AIS-8≥6）的患者出现身体功能障碍的可能性更高，低步速的优势比（95%置信区间）为1.892（1.037-3.453），低握力为1.810（1.110-2.952），TUGT受损为2.491（1.496-4.147）。睡眠质量成分，尤其是维持睡眠和日间功能障碍，与身体功能指标相关。按年龄分层，睡眠质量差与≥75岁参与者中低握力和TUGT受损的发生率较高相关。但在<75岁的患者中未观察到这种关联。按性别分层，观察到女性人群中睡眠质量与TUGT受损之间存在显著关联，而男性人群中未观察到。
