Implication

Mixed methods study reveals limited awareness change but improved knowledge of risk factors in 40-75 year-olds.

Key Points

  • Evaluate the effectiveness of a public awareness campaign for dementia risk reduction in the Netherlands.
  • Conducted cross-sectional online surveys pre- and post-campaign with community-dwelling individuals aged 40-75 years.
  • Assessed awareness and knowledge of dementia risk and protective factors using χ2-tests and t-tests.
  • Employed probit and linear regression to estimate adjusted effects accounting for demographic factors.
  • Performed semi-structured interviews with campaign coordinators to identify implementation facilitators and barriers.
  • No significant change in awareness before (54.6%) and after (55.7%) the campaign (p = 0.334).
  • Knowledge of risk and protective factors increased modestly (mean score from 5.3 to 5.5, p = 0.013).
  • Self-reported campaign exposure linked to higher awareness and motivation for brain-healthy lifestyle changes.
  • Key barriers: limited financial resources, difficulty reaching younger individuals, and low stakeholder engagement.
  • Facilitators included a strong campaign framework and established local networks.
