Abstract

Institutionalization has been associated with social isolation, psychological and cognitive changes, and decreased levels of physical activity in older adults.

Objectives: The aim of this study was to estimate the prevalence of dementia, mild cognitive impairment (MCI), and functional dependence in older adults dwelling in two different Brazilian long-term care facilities (LTCFs).

Methods: This is a cross-sectional study with 185 older people of both sexes, aged 60 years or over, residing in two LTCFs in the city of Montes Claros-MG, Brazil. The diagnosis of MCI and dementia was performed using the Diagnostic and Statistical Manual of Mental Disorders.

Results: Prevalence rates of dementia, MCI, and functional dependence in institutionalized older participants were 62.3, 15.1, and 78.9%, respectively. There was a significant reduction of the Mini-Mental State Examination scores according to the increase of the institutionalization period in LCTFs and the age of older adults (p<0.001).

Conclusions: Prevalence of dementia and functional dependence of older adults residing in LTCFs exhibited higher rates compared to the other older population worldwide. A higher institutionalization period is related to a greater cognitive decline.

A institucionalização tem sido associada ao isolamento social, a alterações psicológicas e cognitivas e à diminuição dos níveis de atividade física em idosos.

Objetivos: Estimar a prevalência de demência, declínio cognitivo leve (DCL) e dependência funcional em idosos residentes em duas instituições de longa permanência (ILPI) brasileiras.

Métodos: Estudo transversal com 185 idosos de ambos os sexos, com 60 anos ou mais, residentes em duas ILPI. O diagnóstico de DCL e demência foi realizado por meio do Manual Diagnóstico e Estatístico de Transtornos Mentais.

Resultados: As taxas de prevalência de demência, DCL e dependência funcional em participantes idosos institucionalizados foram 62,3, 15,1 e 78,9%, respectivamente. Houve redução significativa dos escores do miniexame do estado mental de acordo com o aumento do período de institucionalização nas ILPI e a idade dos idosos (p<0,001).

Conclusões: A prevalência de demência e dependência funcional de idosos residentes em ILPI foi mais elevada em comparação com outras populações idosas em todo o mundo. Um período maior de institucionalização está relacionado a maior declínio cognitivo.
