Abstract: Background:The number of people living with dementia is rising globally due to population aging. Mass media campaigns which aim to reduce the risk of people developing dementia have been conducted across many countries, but few have reported evaluation findings. Objective:The present study investigated the impact of the Your Brain Matters dementia risk reduction campaign in Australia. Methods:The campaign was evaluated by observational cross-sectional surveys of 1000 Australian adults aged 18–75 years before and 24 months after delivery. The national campaign utilized multiple media channels to promote messages about the importance of brain health and reducing the risk of dementia. Dementia risk reduction knowledge, confidence, intentions and actions were measured at baseline and follow-up, and analyzed 2019–2020. Results:Earned television and radio were the most common exposure channels. The proportion of people who understood that it is beneficial to take action to reduce dementia risk before middle age increased (54.1% to 59.4%, OR 1.20 95% CI: 1.01–1.44). There was also an increase (28.5% to 32.8%, OR 1.30, 95% CI: 1.07–1.59) in the proportion who reported taking action to improve brain health. There was no improvement in knowledge about vascular risk factors, or confidence to reduce personal dementia risk. Conclusion:The findings showed some receptivity and positive responses to messages about the benefits of taking action to reduce the risk of dementia. The campaign demonstrated the potential for generating news coverage about this issue, which should highlight the preventive benefits of vascular health behaviors.
