A Systematic Review of Sleep Disturbances in Pediatric Inflammatory Bowel Disease

Abstract Objective The current systematic review (PROSPERO ID: CRD42020220142) aims to characterize sleep health in pediatric inflammatory bowel disease (IBD) and evaluate disease-related and psychosocial prognostic factors associated with sleep disturbances in pediatric IBD. Methods A search of PubMed, PsycINFO, CINAHL, Web of Science, and Cochrane databases was performed. Included studies were written in English, presented original peer-reviewed research, included participants with a mean age of 8–18 years, and reported on at least one quantitative sleep outcome for children with IBD or factors impacting sleep for these children. Studies that did not report on a sleep outcome or factors influencing sleep, or only examined fatigue were excluded. Study quality was evaluated using validated quality assessment tools. The data from the included studies were extracted and synthesized across sleep health domains. Results Database searches yielded 122 records (total participants = 3,905). After full-text and reference/citation searches, 28 articles were included in the review. Methods used to evaluate sleep widely varied across studies and a majority of the studies were cross-sectional. Results suggest that children with IBD may not experience more frequent sleep disturbance than healthy children. Greater sleep disturbance in pediatric IBD was found to be associated with poorer psychosocial functioning and greater active disease/severe symptoms. Conclusions The findings from this review highlight the complex associations between sleep disturbances, inflammation, disease severity, and psychosocial functioning in children with IBD. Additional research with greater methodological rigor (e.g., use of validated sleep measures, longitudinal design, reporting of effect sizes) is warranted to further elucidate these relationships. Summary The current systematic review examines the existing evidence and methods of measurement of sleep disturbances in pediatric inflammatory bowel disease. We describe and evaluate factors associated with sleep disturbance in this population. The quality of evidence, strengths and weaknesses of the literature, and future directions are described.
