Engaging older adults in an online physical activity programme to improve cognition: A qualitative study.

Objectives Maintaining physical activity is a modifiable risk factor for dementia. However, older adults do not routinely meet activity guidelines. Online interventions offer a means of engaging with this group and overcoming barriers to physical activity, particularly in the context of a global pandemic where people have become accustomed to at-home and digital living. This study explored the factors which maximise engagement in an online programme to promote physical activity. Methods A qualitative study was conducted with adults aged 50 and over, recruited through the online UK PROTECT study cohort. Four focus groups (n = 21) examined key contributors to engagement with a digital programme to promote physical activity. Iterative Categorisation was utilised to identify categories and themes of the focus group data. Semi-structured interviews were also conducted (n = 5) in which participants were asked to comment on a concept-stage online intervention. Results Four key themes emerged from focus group data: interaction at the fore, incentives as foundations, fitting around me and identity is critical. The semi-structured interviews identified key areas of programme acceptability and specific needs for enhancing engagement. Conclusions Older adults are open to using online physical activity programmes. Any intervention must be tailored to individual usability preferences and encompass fitness, health and lifestyle needs of older adults. The conceptual-stage intervention used in this study was found to be acceptable, with key changes needed to maximise engagement.
