Effects of Internet-Based Dementia Risk Reduction Education on Risk and Protective Factor Knowledge, Intentions, and Health Behaviors: Randomized Controlled Trial

This internet-based dementia risk reduction e-learning program improved dementia-related knowledge and increased self-reported physical activity, particularly among participants with lower educational attainment. Effects on other health behaviors were limited. These findings support the use of well-designed e-learning as a scalable public health strategy to strengthen dementia risk reduction literacy and encourage selected healthy behaviors.
