The real prevalence of this disease needs to be ascertained in order to establish appropriate measures for improving the quality of life of those affected. The aim of this study was to estimate the prevalence of dementia among elderly Brazilians (> 60 years) through a systematic review of high-quality, population-based, double-blind studies published between 1990 and 2010. DESIGN AND SETTING: Systematic review of prevalence studies. The manuscript was produced in the School of Medicine, Universidade de Brasília. METHODS: Database searches for articles were conducted in Medline (Medical Literature Analysis and Retrieval System Online), Embase (Excerpta Medica database), Lilacs (Literatura Latino-Americana e do Caribe em Ciências da Saúde), SciELO (Scientific Electronic Library Online) and theses and dissertations, using specific keywords. Quality was assessed according to eight criteria for sampling and measurement of findings. RESULTS: Out of 112 articles identified, eleven were included in the qualitative synthesis. In five higher-quality studies from São Paulo, the prevalence rates ranged from 5.1 to 19.0%. No meta-analysis was presented because of heterogeneity among the studies. Poor, illiterate, female and very elderly individuals were the groups most affected. CONCLUSION: The findings from this review did not reflect the reality of the whole country. Although the results brought some information on the prevalence and distribution of dementia in Brazil, cross-sectional studies with consistent methodology are needed CONTEXTO E OBJETIVO: O crescimento rápido da população idosa no Brasil implicou no aumento significativo do número de indivíduos com demência. A prevalência real da doença deve ser constatada a fim de que se possam estabelecer medidas apropriadas para melhorar a qualidade de vida das pessoas afetadas. O objetivo deste estudo foi estimar a prevalência de demência entre a população brasileira idosa (> 60 anos) através da revisão sistemática de estudos populacionais, duplo-cegos, de alta qualidade, publicados entre 1990 e 2010. TIPO DE ESTUDO E LOCAL: Revisão sistemática de estudos de prevalência. O manuscrito foi realizado na Faculdade de Medicina, Universidade de Brasília. MÉTODOS: Os artigos foram pesquisados nos bancos de dados Medline (Medical Literature Analysis and Retrieval System Online), Embase (Excerpta Medica database), Lilacs (Literatura Latino-Americana e do Caribe em Ciências da Saúde), SciELO (Scientific Electronic Library Online) e de teses e dissertaç ões, usando-se palavras-chave específicas. A qualidade foi avaliada de acordo com oito critérios relacionados à amostragem e à mensuração dos achados. RESULTADOS: Dentre os 112 artigos identificados, 11 foram incluídos na síntese qualitativa. Em cinco estudos de melhor qualidade realizados em São Paulo, a taxa de prevalência variou de 5,1% a 19,0%. A metanálise não foi realizada devido à heterogeneidade entre os estudos. Pobres, analfabetos, mulheres e pessoas de idade avançada foram os grupos mais afetados. CONCLUSÃO: Os achados desta revisão não refletem a realidade de todo o país. Embora os resultados mostrem informaç ões sobre a prevalência e a distribuição da demência no Brasil, estudos transversais com metodologia consistente precisam ser realizados 2017-12-07T04:57:18Z 2017-12-07T04:57:18Z 2011 Artigo Sao Paulo Med.
