They were also more likely to report greater knowledge of AD prevention, to have engaged in discussions with providers about dementia risk reduction, and to have received referrals for managing risk factors. Embedding nudge-based messaging into senior centers improved dementia prevention behaviors, cognitive outcomes, and provider practices. These findings highlight the promise of low-cost, scalable strategies for advancing dementia prevention in real-world settings.  \nSESSION 9035 (PAPER)   \nLATE BREAKING: ALZHEIMER’S DISEASE,  \nINCLUDING ALZHEIMER’S DISEASE—RELATED  \nDEMENTIAS VIII  \nAbstract citation ID: igaf122.4279  \nA NUDGE-BASED CAMPAIGN FOR DEMENTIA  \nPREVENTION OUTCOMES: A PRAGMATIC  \nCLUSTER-RANDOMIZED TRIAL  \nJose Aravena1, Hugo Castro2, Ronald Poblete2, Maria Aravena2, Marilu Budinich2, Patricio Fuentes3, Cecilia Albala4, and Becca Levy5, 1.

Yale School of Public Health, New Haven, Connecticut, United States  \nAlthough dementia prevention is a global priority, few interventions have been successfully translated into public health and community settings. To address this gap, we evaluated the effectiveness of a nudge-based Alzheimer’s disease (AD) prevention campaign on dementia prevention outcomes in older adults and healthcare providers. A pragmatic cluster-randomized trial was conducted in seven senior centers in Chile with adults aged ≥60 years who had cognitive impairment but no dementia. Centers were randomized to intervention (n = 3) or control (n = 4) . All participants received usual care, including twice-weekly group activities (physical, cognitive, and social) and healthcare provider dementia training. Intervention centers additionally implemented CULTIVAMENTE, a nudge-based awareness campaign delivered through posters, brochures, and web content. We hypothesized that the intervention would improve cognitive healthy behaviors, cognitive performance (memory, executive function, and prevalence of mild-to-moderate cognitive impairment), and provider practices (AD prevention discussions and referrals). Intention-totreat analyses using linear mixed models and generalized estimating equations confirmed these predictions.
