Ulcerative colitis relapse rate was significantly higher in the poor sleep group than in the non-poor sleep group [34.5% vs 10.3%, p\u2005=\u20050.031]. Multivariate analysis identified chronic poor sleep as a clinical factor that affected inflammatory bowel disease relapse (odds ratio [OR]\u2005=\u20056.69, 95% confidence interval [CI]: 2.23\u201320.0, p\u2005=\u20050.0007] and ulcerative colitis relapse [OR\u2005=\u20058.89, 95% CI: 1.57\u201350.2, p\u2005=\u20050.014].
