Impacto en la calidad de vida por la asociación entre trastornos de sueño y síndrome de intestino irritable Impact on the Quality of Life of the Association between Sleep Disorders and Irritable Bowel Syndrome

Objectives: The objectives of this study were to determine if sleep disorders in patients with irritable bowel syndrome (IBS) were associated with impaired quality of life as measured by the SF36 questionnaire. Methods: This is cross-sectional study in which individuals with IBS according to the Rome III criteria were evaluated for sleep disorders with the Epworth Sleepiness Scale questionnaire and the Pittsburgh Sleep Quality Index (PSQI) questionnaire. They were also evaluated for restless legs syndrome (RLS) and, simulta- neously, the Short Form (36) Health Survey was used to evaluate participants' quality of life. Results: Eighty patients with IBS, mostly women, were included in this study. 81% had some type of spe- cific sleep disorder as measured by at least one of the questionnaires. Patients were groups into those who had sleep disorders, and those who did not. The group which had sleep disorders had statistically significantly more alterations in quality of life (OR 4.8125, 95% CI: 1.17 to 19.02, p <0.0076). Conclusions: This study found that up to 81% of IBS patients have sleep disorders and that sleep distur- bances in patients with IBS are associated with decreased quality of life according to the SF36 scale.
