Description of the 12-week online programme delivered through the Body Brain Life —General Practice (BBL-GP) website

Week	Activity	Description
1	Module 1: dementia literacy	The first module focuses on providing participants with general information about dementia including types, causes, prevalence, social and economic impact, symptoms, brain function, treatment, risk factors (modifiable and non-modifiable) and prevention. This module serves as an introduction to the subsequent modules.
2	Module 2: dementia risk factors	This module is aimed at building awareness and knowledge of the various health conditions associated with an increased risk of AD. Specifically, this module provides details regarding the association between AD and several medical conditions (abnormal weight, high cholesterol, diabetes, hypertension and depression), as well as lifestyle factors (alcohol use and smoking, PA, nutrition, stroke and head injury, mental health, social and cognitive engagement). The module also briefly covers non-modifiable risk factors that contribute to AD, including age and genetics.
3	Module 3: BBL PA	This is a theory-driven, individually tailored module that aims to help participants incorporate regular PA into their daily routine and reduce sedentary behaviour by focusing on increasing endurance, strength, balance and flexibility. This module targets several barriers to engaging in PA, such as increasing motivation, creating opportunities to exercise and developing a social network that supports PA goals.
4	Module 4: BBL nutrition	This is a theory-driven, individually tailored module aimed at helping people develop healthy dietary habits. This module targets the risk associated with abnormal weight, and the protective effects associated with fish intake and other dietary components.
5	Module 5: BBL health self-management	This is a theory-driven, individually tailored module aimed at increasing participants’ health monitoring and management of chronic health conditions. Because several chronic health conditions, such as hypertension, diabetes and high cholesterol, are associated with increased risk for dementia, prevention and appropriate management of such conditions are also likely to be protective against dementia.
6	Module 6: BBL think—cognitive engagement	This is a theory-driven, individually tailored module aimed at increasing participants’ levels of engagement with mentally stimulating activities such as reading, doing crosswords and visiting museums, which is a protective factor against dementia.
7	Module 7: BBL connect—social engagement	This is a theory-driven, individually tailored module aimed at increasing participants’ levels of social engagement. The module targets the risk factor for dementia associated with loneliness and the protective effects of regular social engagement.
8	Module 8: BBL mood	This is a theory-driven, individually tailored module that aims to help participants monitor and maintain good mental health. The module targets risk factors for dementia associated with mental health and mood, focusing on depression and anxiety. Information is provided on symptoms, types, treatment and tips for managing mood.
9	9–12 Self-guided online activities	During these sessions, participants are encouraged to engage in a range of online activities for 1 hour, including accessing many tools they have accumulated during the first 8 weeks. Examples include the goal-setting tool, behaviour-monitoring tool, unhelpful thoughts monitoring tool, videos and so on.
