Objectives: Poor global sleep quality is commonly reported in people with inflammatory bowel disease (IBD) and is linked to poorer health-related quality of life (HRQoL). However, understanding is currently limited by a lack of: (1) longitudinal research and (2) research investigating the impact of specific types of problems sleeping on IBD-related outcomes, particularly on HRQoL., Design: Observational longitudinal cohort study., Methods: N = 276 participants with IBD completed measures at baseline (T1) and 4 weeks later at T2. Four specific sleep disturbances associated with IBD including sleep apnoea, insomnia, restless legs, and nightmares were measured alongside depression, anxiety and stress, and HRQoL., Results: After controlling for participant demographics and clinical characteristics, T1 depression, anxiety, stress, and T1 HRQoL, more severe symptom severity of sleep apnoea (B = -0.30, p < .05) and insomnia symptoms (B = -0.23, p < .05) at T1 significantly predicted poorer HRQoL at T2. However, the experience of restless legs (B = -0.03, p > .87) and nightmares (B = -0.14, p > .11) at T1 did not predict HRQoL., Conclusion: Symptoms synonymous with sleep apnoea and insomnia might represent modifiable risk factors that provide independent contributions to HRQoL over time in those with IBD. These findings suggest that interventions designed to improve sleep apnoea and insomnia could confer benefits to HRQoL in those with IBD. However, more longitudinal research is needed to understand the contribution of sleep disturbances over the longer term, as well as more randomized controlled trials testing the effect of improving sleep on IBD-related outcomes., (© 2020 The Authors.

Inflammatory Bowel Disease (IBD) is commonly associated with poor global sleep quality, and has been posited as a modifiable determinant of IBD related outcomes. However, there is little evidence on the specific types of problems sleeping (e.g., sleep apnea, insomnia etc.) that might characterize the poor sleep quality experienced by those with IBD. The present research aimed to investigate the severity of seven specific types of problems sleeping in those with IBD vs. a healthy control group. This cross sectional comparison study recruited N = 409 with IBD, and N = 377 healthy controls. The Sleep-50 questionnaire was used to assess the presence of seven type of problems sleeping. Multivariate Analysis of Covariance (MANCOVA) was used to compare the severity of sleep disturbances between the IBD and control groups. Those in the IBD group reported significantly more severe experiences of five of the seven domains of the sleep-50, including increased; sleep apnea, insomnia, narcolepsy, restless-legs, and nightmares. More research is needed to; (i) improve the identification and treatment of problems sleeping in routine care; (ii) understand the mechamism(s) of action that links problems sleeping to IBD realted outcomes; and (iii) develop adapted interventions to improve sleep in those with IBD.

Background: Psychological morbidity in young people aged 10-24 years, with inflammatory bowel disease (IBD) is increased, but risk factors for and impacts of this are unclear., Aim: To undertake a systematic literature review of the risk factors for and impact of psychological morbidity in young people with IBD., Methods: Electronic searches for English-language articles were performed with keywords relating to psychological morbidity according to DSM-IV and subsequent criteria; young people; and IBD in the MEDLINE, PsychInfo, Web of Science and CINAHL databases for studies published from 1994 to September 2014., Results: One thousand four hundred and forty-four studies were identified, of which 30 met the inclusion criteria. The majority measured depression and anxiety symptoms, with a small proportion examining externalising behaviours. Identifiable risk factors for psychological morbidity included: increased disease severity (r(2) = 0.152, P < 0.001), lower socioeconomic status (r(2) = 0.046, P < 0.001), corticosteroids (P ≤ 0.001), parental stress (r = 0.35, P < 0.001) and older age at diagnosis (r = 0.28, P = 0.0006). Impacts of psychological morbidity in young people with IBD were wide-ranging and included abdominal pain (r = 0.33; P < 0.001), sleep dysfunction (P < 0.05), psychotropic drug use (HR 4.16, 95% CI 2.76-6.27), non-adherence to medication (12.6% reduction) and negative illness perceptions (r = -0.43)., Conclusions: Psychological morbidity affects young people with IBD in a range of ways, highlighting the need for psychological interventions to improve outcomes. Identified risk factors provide an opportunity to develop targeted therapies for a vulnerable group. Further research is required to examine groups under-represented in this review, such as those with severe IBD and those from ethnic minorities., (© 2016 John Wiley & Sons Ltd.)
