Prevalência dos distúrbios do sono e sua influência na qualidade de vida de uma população dialítica

Abstract

INTRODUCTION: Sleep disorders are among the most prevalent complaints in dialysis patients and are considered an important factor of negative influence on quality of life. OBJECTIVES: To evaluate the prevalence of sleep disorders in dialysis population and study the relationship of these disorders with the quality of life in this group. METHODS: A cross sectional study was conducted on kidney patients on dialysis or peritoneal dialysis. The patients ask specific questionnaires about sleep disturbances, daytime sleepiness and quality of life. RESULTS: The most of the patients were men, 50,95± 15,36 years old, on hemodialysis. Daytime sleepiness was present in 48% and sleep disorders in 17,2%, while poor sleep quality was related in 52,4% of the sample. The most affected dimensions of KDQOL were overhead of renal disease, physical function and, especially, professional profile. The statistical test U of Mann- Whitney showed patients with daytime sleepiness and sleep disorders had a poorer quality of life. CONCLUSION: Sleep disturbances are highly prevalent in ESRD patients and are associated with poorer quality of life. It suggests the need of a multidisciplinary follow- up for these patients, in order to reduce the incidence of sleep disorders and avoid the decrement of their quality of life.
