Abstract

<jats:p>Recent research suggests the positive effect of physical activity on health-related quality of life in people with dementia may be mediated through improved activities of daily living and reduced depressive symptoms. One hundred and twenty-four people with dementia and their informal carers were recruited from the South East of England for this observational study. A subset of participants wore an accelerometer for 30 days. A series of bivariate analyses were completed, alongside mediation analyses. In people with mild to moderate severity dementia, weak positive associations were widely reported between physical activity indices and health-related quality of life, though only a single association reached statistical significance (<jats:italic>r</jats:italic><jats:sub>s</jats:sub> = .25, <jats:italic>p</jats:italic> = .03). Mediation analysis revealed no significant indirect effects across the models after controlling for cognition. Future research needs to explore such relationships with a greater emphasis on the modality and psychosocial components of physical activity rather than just frequency, duration, and intensity.</jats:p>
