Evaluation of a public awareness campaign for dementia risk reduction in the Netherlands: a mixed methods study.
Article in BMC public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAbout 45% of dementia cases are attributable to known modifiable risk factors, yet public awareness remains low. The public awareness campaign "We are the medicine ourselves" (2018-2023) aimed to increase public awareness of dementia risk reduction in nine regions. This mixed methods study evaluated the campaign's effectiveness in reaching individuals aged 40-75 years and explored facilitators and barriers to successful implementation.
methodsCross-sectional online surveys were conducted in independent samples of community-dwelling individuals aged 40-75 years before (n = 4,981) and after (n = 3,379) the campaign to assess awareness of dementia risk reduction, knowledge of dementia risk and protective factors, and campaign exposure. Differences between pre- and post-campaign samples were assessed using χ
resultsNo significant difference in awareness was found between the pre-campaign (54.6% aware) and post-campaign (55.7% aware) samples (adjusted probit regression: z = 0.97, p = 0.334). Knowledge of risk and protective factors modestly increased (from 5.3 to 5.5; B = 0.18, 95% confidence interval: 0.04 - 0.33, p = 0.013). Self-reported campaign exposure was associated with higher awareness, better knowledge of risk and protective factors, and greater motivation to adopt brain-healthy lifestyle changes. Implementation barriers included limited financial resources, difficulty reaching younger individuals (40-60 years), and limited engagement with regional stakeholders. Facilitators included the campaign framework and strong local networks.
conclusionsWhile the multi-regional campaign did not lead to a general increase in population-level awareness of dementia risk reduction, it modestly improved knowledge of specific dementia risk and protective factors.
