Sociodemographic factors associated with public knowledge of dementia in a Cuban population

International organizations estimate that a new dementia is diagnosed every 3 s. OBJECTIVES: To explore the knowledge and beliefs among a cross-section of the adult population of Cuba with regard to dementia risk factors and to determine the demographic variables related with it. A cross-sectional survey was carried out on 1,004 Cubans. METHODS: The survey measured the importance placed on dementia, risk reduction knowledge, and the actions to prevent it. Logistic regression was undertaken to identify variables associated with knowledge. RESULTS: Many respondents (47.5%) believe that dementia risk reduction should start before the age of 40. Cognitive stimulation and physical activities were selected with major frequency. Being older than 48 years, having previous contact with dementia, and university education increases the probability of having healthy lifestyles. CONCLUSIONS: The exploration of demographic variables allows the prediction of likelihood to know about or have positive beliefs in relation to dementia. They should be contemplated into strategies for dementia prevention in Cuban population.
