Prevalence and factors associated with poor sleep quality in inflammatory bowel disease outpatients


Elisa García Calvo, Miguel Durà Gil, Benito Velayos Jiménez, Luis I Fernández Salazar,

Introduction: sleep disorders are common in the general population and have obvious repercussions on quality of life. Poor sleep quality is associated to inflammatory activity and fatigue in inflammatory bowel disease (IBD) patients. This study aimed to analyze the prevalence of poor sleep quality and the factors associated with it, in IBD outpatients. Methods: an observational and prospective study was performed in which epidemiological, clinical and laboratory data were collected from clinical records and patients who consecutively attended an outpatient clinic. Pittsburgh Sleep Quality index (PSQI), Hospital Anxiety and Depression Scale (HADS) and International Physical Activity Questionnaire (IPAQ) were used to measure sleep quality, anxiety, depression and physical activity, respectively. Treatment optimizations, hospital admissions or surgery were prospectively verified three months after the baseline visit. Results: one hundred and two patients were included and 54.9 % had poor sleep quality (PSQI score > 5). No association was found between poor sleep quality and IBD-related variables such as type of disease, ulcerative colitis (UC) extent, Crohn’s disease (CD) location or behavior, time from diagnosis, treatment, prior admissions or surgery and laboratory values. Rotating night shift job (OR 6.116, 95 % CI: 1.312-28.514), HAD score for depression (OR 1.125, 95 % CI: 1.062-1.490) and frequency (days per week) of vigorous physical activity (OR 0.783, 95 % CI: 0.619-0.991) were independent predictors of poor sleep quality. A Pittsburgh questionnaire score higher than 5 was not significantly associated to treatment optimization in the total patient cohort (15.2 % vs 18.2 %, p = 0.451), in UC patients (18.2 % vs 10.7 %, p = 0.362) or CD patients (12.5 % vs 25.9 %, p = 0.198). Conclusions: poor sleep quality is present in more than half of IBD patients. Aspects not directly related to IBD are associated to poor sleep quality.
