Prevalence of cognitive impairment and associated factors among the elderly in Bagé, Rio Grande do Sul, Brazil
It is estimated that until 2020 the elderly will represent 13% of the total Brazilian population, and there is increasing concern about healthy aging and low rates of cognitive impairment. This cross-sectional study aimed to identify the prevalence of cognitive impairment, using the Mini-Mental State Examination (MMSE) in a sample of 1,593 elderly aged 60 years old and more who were living in the community of the city of Bagé, Southern Brazil, in 2008. The Poisson regression model was used for estimating crude and adjusted prevalence ratios; their related 95% confidence intervals and p-values lower than 0.05 were considered statistically significant. The prevalence of cognitive impairment was of 34% and statistically associated with gender (female), age (older), schooling (less educated), lower economic classes, without retirement, with depression and functional limitation. The high magnitude with increased occurrence among poor and vulnerable groups contributes to the implementation of public policies in order to improve care, prevent diseases and promote the independence and autonomy of the elderly population.
