Individuals with inflammatory bowel disease (IBD) experience overlooked deficits in objectively measured cognitive functioning; however, there is limited knowledge about self-reported cognitive symptoms in this group. Sleep characteristics, such as insomnia, poor sleep quality, or fragmented sleep, may be key modifiable factors that are associated with cognitive symptoms among individuals with IBD. This study aimed to describe cognitive symptoms and examine the relationship between these symptoms and sleep characteristics among adults with IBD. We conducted a descriptive, cross-sectional study using the Pittsburgh Sleep Quality Index, wrist actigraphy, the Insomnia Severity Index, and the FACT-Cog Perceived Cognitive Impairments subscale. Bivariate statistics were used to evaluate relationships between variables. The sample included 83 participants (mean age 40.44 years [standard deviation 10.7], 71% female). Over 77% ( n = 60) had poor self-reported sleep quality, and 69.5% ( n = 57) had clinically meaningful insomnia. The most frequently reported cognitive symptoms (experienced two or more times a week) were trouble concentrating (51.3%), forgetting names (43.8%), forgetting intended tasks (38.9%), and slow thinking (37.6%). Insomnia severity was moderately correlated with three out of the four most common cognitive symptoms (trouble concentrating: r s = .51, p < .01; forgetting intended tasks: r s = .38, p < .01; slow thinking: r s = .46, p < .01). Future research is needed to examine relationships between objective cognitive measures and sleep characteristics and to test the effects of insomnia treatment on daytime cognitive symptoms in this complex patient population.

Abstract Background Research is limited on the impacts of menopause, defined as the permanent cessation of ovarian function and decline of reproductive hormones, on gastrointestinal symptom severity and disease progression in women with inflammatory bowel disease (IBD). This review synthesizes current evidence on the impact of menopause, menopause transition, and hormonal therapy (HT) on disease activity, IBD and menopause symptom severity, and disease progression among individuals with IBD. Methods A systematic literature review was reported following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines and preregistered at PROSPERO (CRD42024564901). Five databases were searched without date restrictions. Data extraction and risk-of-bias assessment were performed independently by multiple reviewers. Results were qualitatively synthesized. Results Of 1667 records, 15 studies met inclusion criteria (5 cohort, 3 case-control, 7 cross-sectional) with IBD sample sizes from 37 to 1367. Evidence on HT and IBD risk was mixed: some studies linked HT to increased ulcerative colitis risk while others found no significant association after adjusting for confounders. Women with IBD experience earlier menopause than healthy control subjects. While most women reported no change in IBD symptoms postmenopause, a minority reported symptom worsening. HT may reduce flare severity. Women with IBD reported more severe vulvovaginal symptoms and had distinct vaginal microbiome profiles compared with healthy control subjects. Conclusions Few studies have explored the relationship between menopause and IBD. There is a need for continued research on the relationship between IBD disease activity and menopause symptoms to create tailored interventions to improve women’s health with IBD across the lifespan.

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.

Abstract Introduction The majority of adults with inflammatory bowel disease (IBD) experience disability which is not fully explained by disease activity. Up to 80% of adults with IBD experience poor sleep health, which is associated with disability in other populations; however, the relationship between disability and sleep health among patients with IBD is largely unexamined. The purpose of this study was to compare the sleep health characteristics of those with and without IBD-related disability. Methods We recruited adults (18 to 59 years old) with IBD from a single academic medical center from 2022 to 2024. We measured disease activity using the Manitoba IBD Index and sleep using the PROMIS Sleep Disturbance and PROMIS Sleep-Related Impairment scales, the Insomnia Severity Index, and 14 days of wrist-worn actigraphy (Phillips Spectrum Plus, Phillips Respironics). We asked participants how many days they missed or had at least 50% reduced productivity in paid work or household work or missed leisure activities in the last 3 months related to their IBD. Disability was defined as missing six or more day over three months. We conducted bivariate analyses and logistic regressions to study associations. Results Among 83 adults with IBD [mean age = 40.4 years (SD 10.7), 59 (71.1%) were female, 56 (71.1%) had Crohn’s disease], and 49 (62.0%) had IBD-related disability. Patients with disability had more severe sleep disturbance (56.4 vs. 51.0, p &lt;.001), sleep-related impairment (58.3 vs 50.3, p &lt;.001), more severe insomnia (12.7 vs. 9.4, p =.029), and actigraph-measured higher wake after sleep onset (41.6 minutes vs. 34.0 minutes, p = 0.012) and lower sleep efficiency (85.1% vs. 87.9%, p = 0.032) compared to those without disability. After controlling for age and disease activity, sleep-related impairment (OR = 1.1, 95% CI 1.03, 1.15) was independently associated with disability. Conclusion Patients with IBD-related disability experience poor sleep health. Sleep related daytime impairment uniquely contributed to disability when controlling for disease activity. Sleep interventions need to be tested in adults with IBD to determine if they are effective at addressing disability in this population. Support (if any) Mayo Clinic Bonner Fund

Purpose: Fatigue is one of the most common and disabling symptoms experienced by people with inflammatory bowel disease; however, interventions to treat fatigue are limited. The purpose of this systematic review is to examine the relationship between sleep deficiency and fatigue in adults with inflammatory bowel disease and to describe the demographic and clinical factors associated with fatigue to inform future intervention work. Methods: We conducted a systematic review and reported the results using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The search was conducted using MEDLINE, EMBASE, PsycINFO, CINAHL, and CENTRAL on 3/7/24. We included studies with adults (≥18 years of age) who had a diagnosis of inflammatory bowel disease (Crohn’s disease, ulcerative colitis, or indeterminate colitis) and measured fatigue and sleep using a validated self-report questionnaire or objective measurement. Results: Twenty-two studies met inclusion criteria for a total sample of 16 927, of whom 58.7% (n = 9937) had Crohn’s disease, and 66.3% (n = 11 226) were female. 56.1% of the participants experienced fatigue and 66.3% experienced sleep deficiency. Sleep quality and insomnia were consistently associated with fatigue. Baseline poor sleep quality was associated with persistent and worsening fatigue over 12 to 24 months. Clinical but not objective assessment of disease activity, anxiety, depression, female gender/sex, and younger age were also associated with more severe fatigue. Conclusions: Sleep quality and insomnia represent important modifiable contributors to fatigue. Future research should explore whether sleep interventions can improve fatigue in this population.

Abstract Background and Aims Individuals with inflammatory bowel disease (IBD) experience a high symptom burden, including abdominal pain, fatigue, anxiety, depression, and sleep disturbances; yet, little is known regarding the relationship between sex and gender on symptoms. We sought to report symptom severity for cisgender men, cisgender women, and transgender and gender-diverse (TGD) individuals. In addition, we used network analysis to identify core symptoms and explore if symptoms and their relationships differ between cisgender men and cisgender women. Methods This was a cross-sectional study. We recruited adults with IBD online through ResearchMatch. Individuals responded to Patient-Reported Outcomes Measurement Information symptom questionnaires, as well as demographic and clinical questionnaires. Network analysis was used to identify the core symptoms driving the symptom structure. Results One-hundred and fifty-seven (63.3%) participants identified as cisgender women, 84 (33.9%) as cisgender men, and 7 (2.8%) as TGD. Cisgender men (M = 61.8) and TGD (M = 61.3) groups reported higher abdominal pain levels compared with cisgender women (M = 57.8; P = .02). Transgender and gender-diverse individuals reported higher depression levels (M = 64.8) compared with cisgender men (M = 56.7) and cisgender women (M = 54.4; P = .01). Using a network analysis approach, anxiety and fatigue emerged as core symptoms for the entire sample (clinically active and inactive disease), and among only those with active clinical disease. Fatigue was a top core symptom for cisgender women; anxiety emerged as a top core symptom for cisgender men. Conclusions This study highlights that fatigue and anxiety are core symptoms among individuals with IBD and demonstrates a potential sex and/or gender difference in core symptoms. Replication of this study is needed with further consideration of inclusion of TGD patients.

Abstract Introduction Inflammatory Bowel Disease (IBD) is a chronic, immune-mediated condition, encompassing Crohn's disease (CD) and ulcerative colitis (UC). Up to 80% of individuals with IBD report poor sleep quality. However, there is limited information on factors that predict sleep characteristics in this population. This study aims to explore the associations between demographic, clinical, and psychological factors with sleep characteristics in adults with IBD. Methods We conducted a retrospective analysis of two IBD sleep studies. Participants aged 18-64 years old with a diagnosis of IBD were recruited from two academic medical centers and completed Patient-Reported Outcomes Measure Information System (PROMIS) depression and anxiety questionnaires and wore a wrist actigraph for 10 days continuously. We employed Independent T-Tests and Pearson’s correlation to assess the association of biologic treatment, IBD type, sex, depression, and anxiety on sleep efficiency (SE), total sleep time (TST), and sleep onset latency (SOL). Results We included 58 participants with a mean age of 35.6 years (SD=12.1). 60.3% were female, and 60.3% were diagnosed with CD. The mean depression score was 51.3 (SD = 10.2) and the anxiety score was 52.2 (SD = 15.5). The mean SOL was 19.3 minutes (SD = 15.5), TST was 413.3 minutes (SD = 53.2), and SE was 83.5% (SD = 5.7). TST was significantly longer in females compared to males (427.4 vs. 391.9 minutes , p&lt; 0.05). SE was significantly higher among females compared to males (85.1% vs. 81.0%, p&lt; 0.001) and among individuals with Crohn's disease compared to Ulcerative colitis ((85.1% vs. 81.0%, p&lt; 0.01). SOL was longer among individuals with Ulcerative colitis compared to Crohn's disease (15.6 vs.25.0minutes , p&lt; 0.05). Depression and anxiety scores were not significantly correlated with any sleep characteristic. Conclusion Sleep continuity was poor in people with IBD. Given that we found sex and IBD type impacted sleep continuity, these factors should be considered in future precision sleep health interventions for this population.

Abstract Introduction Inflammatory bowel disease (IBD) is a chronic immune-mediated disease that includes Crohn’s disease and ulcerative colitis. People with IBD experience poor sleep health, including short and highly fragmented sleep and extraintestinal manifestations including alterations to cognitive functioning; however, the relationships between sleep health and cognitive symptoms have not been evaluated in this population. The purpose of this study was to identify the associations between sleep health and perceived cognitive impairments in adults with IBD. Methods We conducted a descriptive, correlational study of adults (18 to 59 years old) with IBD. We used the Pittsburgh Sleep Quality Index (PSQI) to obtain self-reported data on sleep health, the FACT-Cog Perceived Cognitive Impairments questionnaire to elicit cognitive symptoms, and the Manitoba IBD Index to describe IBD disease activity. Descriptive statistics, point-biserial correlations, and Pearson’s correlations were used to describe relationships. Results Of the 59 participants [Mean age 40.8 (SD 10.5), 71.2% female, 94.9% white], 67.8% (n=40) had clinically active IBD. 79.7% (n=47) had a PSQI total score &gt;5, indicating poor sleep health. The most common cognitive symptoms, occurring two or more times a week, were trouble concentrating (55.9%), walking into a room and forgetting an intended task (44.1%), and forgetting the names of people soon after being introduced (44.0%). PSQI total score was positively and significantly correlated with 12 of 13 questions on the FACT-Cog. The strongest correlations included trouble concentrating (r = .497, P&lt;.001), slower thinking (r = .450, p&lt;.001), trouble forming thoughts (r=.550, p&lt;.001), and difficulty finding the right words to express oneself (r=.546, p&lt;.001). Longer self-reported sleep latency was associated with higher frequency of 12 out of 13 cognitive symptoms, while sleep efficiency was associated with 4 and sleep duration was associated with 2. Having clinically active IBD was associated with trouble forming thoughts (r=-.261, p=.046), slower thinking (r=-.307, p=.018), and trouble concentrating (r=-.346, p=.007). Conclusion Cognitive symptoms are common among people with IBD, highly correlated with sleep health, and not fully explained by IBD disease activity. Future studies should include objective measures of sleep health and cognition to further elucidate these relationships. Support (if any) Mayo Clinic Bonner Fund
