Does sleep impact mobility in adults? A scoping review

ObjectiveTo review the literature on if sleep impacts mobility in adults. Review method usedThis scoping review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews (PRISMA - ScR) guidelines and the Joanna Briggs Institutes (JBI) updated methodology for scoping reviews. Data sourcesOvid Medline, Web of Science, Embase.com, and CINAHL databases were searched. Google Scholar and hand-searching were further reviewed for grey literature. Review methodsSeven of the authors participated in the data screening and extraction process. Citations were randomly divided so that each was screened separately by two team members. Similarly, data were extracted from included articles independently by two reviewers with a third dedicated to resolving discrepancies. ResultsThe search strategy generated 8,772 references, 697 articles underwent full-text screening, and 108 eligible articles were included in the scoping review. Most studies (n = 69; 64%) included only self-reported sleep, and "walking" was the most common mobility category (n = 99). Most studies (n = 60; 56%) reported a positive association between sleep and mobility, indicating better sleep was associated with better mobility or worse sleep was associated with worse mobility. Most studies including people with cardiovascular, kidney, metabolic, mental health, neurological, and pulmonary conditions reported a positive association between sleep and mobility. ConclusionMost studies reported a positive association between sleep and mobility. However, due to the variety of sleep and mobility outcomes used, it was challenging to compare studies and synthesize results. Further, due to a relatively small sample size and variety of health conditions, conclusions cannot be drawn, and further research is needed.
