Objectives Evaluate the effect of a health promotion campaign aimed at increasing awareness about dementia risk reduction in middle-aged community-dwelling individuals in the Netherlands. Design A 10-month public health campaign using mass media and community participation, supported by eHealth. Population-level difference in awareness before and after the campaign, including variation between demographic groups, was assessed in two independent cross-sectional samples from the same target population.

Three specific districts within the Province were chosen for an additional community participation approach, in which local stakeholders were invited to support the campaign. Results No pre- (n=590) post- (n=602) difference was observed in people agreeing to the statement that dementia risk reduction is possible (X-2(1)=1.27, p=0.260). For the individual lifestyle factors, physical activity (7.6% increase (X-2(1)=7.48, p=0.006)) and healthy diet (10.5% increase (X-2(1)=12.37, p
