Background: Engagement in physical activity is associated with reduced dementia risk but insufficient physical activity is a global trend. Objectives: We aimed to explore what advice might be offered to others to increase physical activity and to identify enablers and barriers to physical activity for adults interested in dementia prevention and participating in a massive open online course. Participants: Two thousand, one hundred and thirty-two participants contributed to an online discussion forum. Design: Analysis was conducted using Topic modelling analysis followed by thematic analysis. Results: The themes generated from the discussion posts included time constraints, poor health and lack of motivation as barriers to physical activity, and social interaction, incidental activities, and dog ownership as enablers. Peer advice was frequently suggested around scheduling physical activity into the day and joining a friend or organised activity. Conclusion: This online discussion forum uniquely captured ideas from a large, diverse group of participants. Future research may benefit from further examining the role of discussion forums and peer advice in dementia risk reduction initiatives.
