[Sleep, fragility and cognition: a multicenter study with Brazilian elderly].

This study aimed to analyze the joint influence of background variables (age, gender, and income), weakness and sleep disorders on cognition in elderly community residents. This is an excerpt from the multicenter project Frailty in Elderly Brazilians (FIBER). We evaluated 878 patients, using socio demographic questionnaire, questions about sleep disorders (Nottingham Health Profile); issues nap (Minnesota Leisure Activity Questionnaire) and MMSE (cognitive screening). The Mann Whitney and Kruskal Wallis test and regression analysis were used univariate and multivariate data analysis, with a significance level of 5% (p <0.05). The results showed that elderly patients with lower MMSE scores were those with lower family income, female and older. Health professionals can develop preventive actions in relation to cognition, thus maintaining the autonomy and independence in daily activities of the elderly.
