Abstract in Portuguese
Objetivo: Estimar a prevalência de déficit cognitivo em uma base populacional de idosos, utilizando-se os diferentes pontos de corte do Mini-Exame do Estado Mental (MEEM) recomendados por autores brasileiros e verificar a distribuição em percentis da pontuação do MEEM na população estudada. Método: Participaram do estudo 1558 (89,4% do total) indivíduos com idade ≥60 anos residentes na cidade de Bambuí, MG, que foram submetidos ao MEEM. Resultados: A prevalência estimada de déficit cognitivo variou de 13,2% a 27,0%, dependendo do ponto de corte utilizado, observando-se grande variação na sua concordância (índices de kappa entre 0,38 e 0,88). O ponto de corte de 13/14 correspondeu ao 5º percentil e o de 21/22, ao quartil inferior da distribuição dos escores do MEEM. Conclusão: Na ausência de pontos de corte comparáveis, a distribuição em percentis é mais adequada para estudos de base populacional de idosos com baixa escolaridade
Abstract
Objective: To estimate the prevalence of cognitive impairment in an elderly population-based cohort, using several Mini-Mental State Examination (MMSE) cut-off points recommended by Brazilian authors and to examine the percentile distribution of MMSE scores in the study population. Method: A total of 1558 subjects aged ≥60 years (89.4% of the total), living in the city of Bambuí, MG, completed the MMSE and were included in the present study. Results: The estimated prevalences of cognitive impairment varied from 13.2% to 27.0% depending on the cut-off point and agreement varied widely between them (kappa range: 0.38 to 0.88). Cut-off point 13/14 corresponded to the 5 th percentile and 21/22 corresponded to the lower quartile of the MMSE score distribution. Conclusion: In the absence of comparable cut-off points, percentile distributions are more adequate for population-based studies of elderly with low schooling level.
