ABSTRACT=<sec><title>Objective</title><p>The relationship between sleep problems and walking speed has been less explored. The present cross-sectional study was to investigate the association between sleep quality and sleep duration and gait speed in Chinese adults.</p></sec><sec><title>Methods</title><p>A total of 13,367 participants were recruited in this cross-sectional study, retrieving the data from the Global Aging and Adult Health Survey (SAGE). Gait speed was measured using the 4-m walking test. Age, sex, education years, smoking status, alcohol consumption, physical activity, chronic disease, sleep problems were self-reported by participants. To explore the association between sleep problems and gait speed, multivariate linear regression models were employed.</p></sec><sec><title>Results</title><p>In the adjusted model, poor sleep quality and longer sleep duration were significantly associated with slower normal walking speed in Chinese adults (<italic>p</italic> &lt; 0.001). Moreover, there were negatively significant associations between normal gait speed and sleep quality in male adults (<italic>p</italic> &lt; 0.01).</p></sec><sec><title>Conclusion</title><p>The findings suggest that slower normal walking speed was associated with poor sleep quality and longer sleep duration (&gt;8 h) in Chinese male adults.</p></sec>
