Association between sleep disorders and frailty status among elderly

Objective: To analyze the association between nap frequency with frailty status, gender, age, education, family income and the five criteria of frailty. Methods: This is a cross-sectional study assessing 3,075 elderly who met the inclusion criteria. The sociodemographic characterization, cognitive status measures, frailty and nap status were performed. Data were analyzed using descriptive statistics and non-parametric tests for statistical inference. Results: Most elderly napped during the day (61.7%), with an average frequency of 5.9 days per week (SD=1.9). A significant association was found between nap frequency and the frailty dimension of "energy expenditure in physical activity". Conclusion: No significant association was found between nap frequency and selected sociodemographic variables and frailty status among the elderly, except for the criterion of frailty "energy expenditure in physical activity".
