Examining Mediating Factors in the Relationship Between Sleep Disturbance and Symptoms in Adults with Inflammatory Bowel Disease

Abstract

Limited studies have explored the effects of individual and environmental factors on sleep disturbance in individuals with inflammatory bowel disease (IBD), which is vital for informing future sleep interventions. Thus, the purpose of this study was to explore the possible mediated effects of potential precipitating and/or perpetuating factors on the relationship between sleep disturbance and symptoms in adults with IBD. This is a correlational study of adults with IBD recruited from ResearchMatch. Survey questions asked about demographics, clinical characteristics, sleep hygiene, sleep beliefs and attitudes, sleep environment, sleep control, and symptoms (sleep disturbance, abdominal pain, anxiety, depression, fatigue). Data analysis included descriptive statistics, Pearson correlations, and mediation analysis. We included 250 adults with IBD (M = 37.9 years old, 64.8% female, 72.4% white). Fifty-four percent of the sample self-reported having a diagnosed sleep disorder. Sleep hygiene and sleep beliefs and attitudes significantly mediated the relationship between sleep disturbance and symptoms (i.e., fatigue, depression, anxiety, and abdominal pain). Whereas the sleep environment and sleep control did not significantly mediate the relationship between sleep disturbance and symptoms. Individuals with IBD experience sleep disturbances, alongside symptoms of anxiety, depression, abdominal pain, and fatigue. Mediation analysis identified sleep hygiene and sleep beliefs, and attitudes as partial mediators. Considering cognitive-behavioral therapy for insomnia is recommended for restructuring these mediating factors. Participants also faced moderate environmental disturbances, suggesting a need for further investigation in this population.
