Incapacidade funcional, sono e dor lombar aguda em idosos que vivem na comunidade

Abstract

The Lower Back Pain (LBP) is a common condition among the older people that is associated with several negative outcomes such as limitations in doing activities of daily living, decline in quality sleep and social participation restrictions. These outcomes have been widely described as predictors of worse quality life, higher hospitalization rate and mortality in the elderly age. This study aimed to investigatethe association of disability with the intensity of LBP, the sleeping quality, use of medication and sociodemographic variables among community dwelling older adults with acute LBP. It is a cross-sectional study in a subsample of elderly patients ( 60 years) international multicenter study Back Complaints in the Elders (BACE). Seniors who had a new acute episode of DL were included in the sample, the elderly being excluded with cognitive, visual and hearing impairments. Sociodemographic andpharmacological data and instruments were used Visual Numerical Scale for pain (EVN) to investigate the intensity of pain; Pittsburg Sleep Quality Index (PSQI) to investigate the quality of sleep in the last month; and Roland Morris Disability Questionnaire (RMDQ) to investigate the resulting disability of the DL. Data were analyzed using the Spearman correlation test to determine correlations and Multiple Linear Regression (Model Backward) to examine associations between explanatoryvariables and the dependent variable, with a 5% significance level. The findings showed that older people with acute DL showed significant disability, pain intensity from moderate to severe, and they are satisfied with the quality of sleep, despite the presence of difficulty sleeping presented. However, there were no strong correlations between disability with pain and sleep. These results provide data for future researchlinking the strategies used by elderly people with DL to deal with functional demands, even in the presence of pain.
