Abstract

The natural aging process and the diseases that affect the elderly are frequent causes of decline in functional independence, which may compromise autonomy and performance of activities of daily living for a significant percentage of the elderly people. Nevertheless, sleep disturbances are frequently observed in this age group. Sleep quality is a fundamental factor of influence on quality of life and engagement in productive and leisure activities. Its consequence to health and well-being is well known, however, the relationship between sleep quality and functional independence has been little explored in literature. The goals of this study were: to explore the relationship between sleep quality and functional independence of elderly people in long-term care facilities, as well as between those variables, socio demographic characteristics and participation in productive and leisure activities, and to identify the influence factors for the functional independence. Specific instruments were used to evaluate sleep quality (Pittsburgh Sleep Quality Index - PSQI) and functional independence (Functional Independence Measure - FIM), along with instruments designed by the author in order to gather information about occupational routine, socio demographic and health related issues. The present study recruited 48 subjects living in a nursing home for at least one year, without dementia, depression, blindness with insensibility to light and no previous diagnoses of sleep disturbance. 18 subjects are women (37,5%) and 30 are men (62,5%), mean age: 71,7(±8,2) years old. Most of the elderly (69%) showed poor sleep quality as measured by the PSQI (mean 8,0 ± 3,9). Elderly with better subjective sleep quality and those showing less latency obtained higher scores on FIM motor domain. Elderly showing better sleep efficiency and more frequent complaints of noctúria obtained higher scores on MIF's total score and motor domain. Better scores on MIF's cognitive domain were related to better educational level. (AU)
