PMID 40414548WHAT IT FOUND
Older adults with poor sleep quality reported lower physical function, greater disability, and less walking confidence than those with good sleep.
They also walked slower and had lower performance scores. No association was found with figure-of-8 walking skill.
Key findings
01Participants with poor sleep quality had lower scores in overall function, disability frequency, disability limitations, and walking confidence compared to those with good sleep quality.
02Those with poor sleep quality demonstrated slower gait speed, shorter six-minute walk distance, and lower Short Physical Performance Battery scores.
03The association between sleep quality and performance on the Figure-of-8 Walk Test did not survive covariate adjustment.

What it does not show
This is a cross-sectional analysis, so it cannot determine if poor sleep causes functional limitations or if limited function disrupts sleep. The study was a secondary, unplanned analysis of baseline data from a trial not focused on sleep, with no formal correction for multiple comparisons. Sleep quality was measured by self-report, which may not align with objective measures like actigraphy. The lack of association with the Figure-of-8 Walk may be due to a restricted range of motor skill performance in this specific sample. Not all potential confounders, such as lifestyle or environmental factors, were fully addressed.
Declared interests
The study was supported by the National Institutes of Health (Extramural). No other conflicts of interest are explicitly detailed in the provided text.
The easy way to misread this
Do not assume that improving sleep quality will directly improve physical function or disability. This study shows an association, not causation, and the results are cross-sectional, meaning poor sleep could be a consequence of existing health or functional issues rather than the cause.
