ABSTRACT

Dementia is a very common disease, but the general population's knowledge about its main etiology, Alzheimer's disease (AD), is still poor, leading to delayed seeking of healthcare services, less prevention of disease by lifestyle changes and more difficulty in managing the care of the demented.

Objective: To measure knowledge about AD in a Brazilian sample, taking into account some demographic variables.

Methods: A link to a self-administered online questionnaire was sent by email and via other social media to anyone older than 18 years old. Our questionnaire contained sociodemographic questions and the Alzheimer's Disease Knowledge Scale (ADKS), a well-established scale comprising 30 “true or false” questions about AD.

Results: 1,414 people (1,076 females), with a mean age of 42.3 years (SD ± 14.1), and 87.4% having more than 11 years of schooling, answered the online questionnaire. The mean total score for the ADKS was 21.6 out of 30 points (SD ± 3.73); however when we excluded health professionals (36.4% of the sample), it dropped to 20.5/30 (SD ± 3.51). The scores were positively influenced by educational level, professional skills (better for health professionals, mainly physicians) and by age (younger than 65 years). Being a caregiver or family member did not influence the knowledge about disease.

Discussion: Despite the high prevalence of AD, few studies have been conducted in Brazil regarding the population's knowledge about the disease. Our study revealed a lack of information about AD in our country, even in relatives and caregivers of demented patients.

RESUMO

Apesar da alta e crescente prevalência de demência em nosso meio, o conhecimento da população sobre sua principal causa - a Doença de Alzheimer (DA) - é insuficiente, levando à menor procura por serviços de saúde, menor prevenção da doença por meio de mudanças no estilo de vida e maior dificuldade no cuidado aos pacientes com demência.

Objetivo: Mensurar o conhecimento sobre DA em uma amostra da população brasileira, levando em conta algumas variáveis demográficas.

Métodos: Um link para um questionário online auto-aplicável foi enviado por email e por meio de outras mídias sociais para pessoas com mais de 18 anos de idade. O questionário era composto por ítens sociodemográficos e pela “Alzheimer's Disease Knowledge Scale” (ADKS), uma escala bem estabelecida composta por 30 questões relacionadas à DA, no formato “verdadeiro ou falso”.

Resultados: 1414 pessoas (1076 mulheres), com idade média de 42,3 anos (DP ± 14,1) e mais de onze anos de escolaridade em 87.4%, responderam o questionário online. A pontuação média na escala ADKS foi de 21,6 em 30 pontos possíveis (DP ± 3,73). Contudo, excluindo profissionais de saúde (36,4% da amostra), a pontuação média caiu para 20,5 (DP ± 3,51). Os resultados foram influenciados positivamente pela escolaridade, profissão (profissionais de saúde, principalmente médicos, tiveram melhor desempenho) e idade inferior a 65 anos. Cuidadores e familiares de pessoas com demência não tiveram melhor desempenho que os demais.

Discussão: Apesar da alta prevalência da DA, poucos estudos brasileiros avaliaram o conhecimento da população sobre esta doença. O nosso estudo revelou falta de informação da população brasileira em relação a este tema, mesmo entre familiares e cuidadores de pessoas com demência.
