Small Steps Towards Improving Activity and Sleep Habits to Decrease the Risk of Dementia
This is a randomised controlled study aiming to evaluate the implementation of a website ('Small Steps') to support the modification of participants' time-use behaviour to reduce the risk factors for dementia. 'Small Steps' website provides the tools for this with a visual representation of the participant's current use of time and allowing manipulation to demonstrate how small lifestyle changes may improve and meet sleep and physical activity needs. Participants will be assisted to make changes to current behaviours with the aim to reduce the time they spend sitting (sedentary behaviour), increase physical activity, and improve sleep duration and quality.

Participants (aged 65 or older) will be randomly allocated to one of two groups, the 'Extended Program' (intervention) group or the 'Condensed Program' (control) group.

There are 3 phases (Introductory, Maintenance and Follow-Up; each 12-weeks long) to this program and in total the program is 36-weeks long. Participants will use a tailored website to help support them in making progressive changes over the first 12 weeks. They will then try to maintain these behaviour changes for as long as possible. There will be in-person health testing during each phase and information about sleep habits, sleep quality, and motivation will be assessed using online surveys. Physical activity levels and sleep duration will also be assessed.
