Abstract

OBJECTIVES

This study aimed to examine the association between sleep quality and physical performance among a group of UK community-dwelling older adults, according to sex.

METHODS

Sleep quality was assessed using the Pittsburgh Sleep Quality Index. Physical performance was assessed using a short physical performance battery (SPPB), a timed up-and-go, and a hand-grip strength test.

RESULTS

Of 591 eligible study members, 401 completed the Pittsburgh Sleep Quality Index. In regression analyses, men who reported poor sleep quality were significantly more likely to have a poor SPPB score, even after adjustment for confounding factors (OR = 2.54, 95% CI 1.10-5.89, P= .03). The direction of the relationship was reversed among women, where those who reported poor sleep were less likely to have a low SPPB score (OR = 0.36, 95% CI 0.15-0.85, P = .02). Poor sleep quality was associated with poorer hand-grip strength among women (regression coefficient = -0.34 z score, 95% CI -0.64, -0.04, P = .03), but this relationship was not observed among men (regression coefficient = 0.28 z score, 95% CI -0.01, 0.57, P = .06).

CONCLUSION

We found evidence of an association between poor sleep quality and poorer physical performance in older adults, though there appear to be important sex differences.

摘要

目的

本研究旨在根据性别，调查英国社区居住的老年人群中睡眠质量与身体表现之间的关系。

方法

使用匹兹堡睡眠质量指数评估睡眠质量。使用简短身体表现电池（SPPB）、计时起立行走测试和握力测试评估身体表现。

结果

在 591 名符合条件的研究参与者中，有 401 名完成了匹兹堡睡眠质量指数。在回归分析中，报告睡眠质量差的男性更有可能表现出较差的 SPPB 评分，即使在调整混杂因素后也是如此（OR=2.54，95%CI 1.10-5.89，P=0.03）。女性的关系方向相反，报告睡眠质量差的女性不太可能 SPPB 评分较低（OR=0.36，95%CI 0.15-0.85，P=0.02）。睡眠质量差与女性握力下降有关（回归系数=-0.34 分位数，95%CI -0.64，-0.04，P=0.03），但这种关系在男性中并未观察到（回归系数=0.28 分位数，95%CI 0.01，0.57，P=0.06）。
