title: Sleep disturbance and risk of active disease in patients with Crohn's disease and ulcerative colitis.
abstract: OBJECTIVE
  Impairment of sleep quality is common in patients with inflammatory bowel diseases (IBDs) (eg, Crohn's disease [CD] and ulcerative colitis [UC]), even during clinical remission. Sleep impairment can activate inflammatory pathways. Few prospective studies have examined the role of sleep disturbance on risk of relapse in IBD.
  
  
  METHODS
  We analyzed data from 3173 patients with IBD (1798 in clinical remission at baseline) participating in the Crohn's and Colitis Foundation of America Partners study, a longitudinal, Internet-based cohort. Sleep disturbance was measured using a subset of questions from the Patient Reported Outcomes Measurement Information Systems sleep disturbance questionnaire. Disease activity was assessed using the short Crohn's Disease Activity Index and the simple clinical colitis activity index for CD and UC, respectively. Logistic regression was used to identify predictors of sleep quality and examine the effect of sleep quality at baseline among patients in remission on risk of active disease at 6 months.
  
  
  RESULTS
  Disease activity, depression, female sex, smoking, and use of corticosteroids or narcotics were associated with sleep disturbance at enrollment. Among 1291 patients whose CD was in remission at baseline, those with impaired sleep had a 2-fold increase in risk of active disease at 6 months (adjusted odds ratio, 2.00; 95% confidence interval, 1.45-2.76); however, no effect was observed in patients with UC (odds ratio, 1.14; 95% confidence interval, 0.75-1.74). These findings persisted in a number of sensitivity analyses.
  
  
  CONCLUSIONS
  Sleep disturbance was associated with an increased risk of disease flares in CD but not UC. These findings indicate that the evaluation and treatment of sleep disturbance in patients with CD might improve outcomes.
