Perceptions and psychosocial impact of food, nutrition, eating and drinking in people with inflammatory bowel disease: a qualitative investigation of food-related quality of life

Food Related Quality of Life and Associations With Demographic and Clinical Characteristics in People With Coeliac Disease

BACKGROUND

Coeliac disease is an autoimmune disorder resulting from the consumption of gluten in genetically susceptible individuals. Current treatment is a lifelong gluten-free diet that significantly affects quality of life. Food-related quality of life (FRQoL) refers to the impact of food, nutrition, eating and drinking on the psychosocial aspects of life. The aim of this study was to examine FRQoL in patients with coeliac disease.

METHODS

Patients with confirmed coeliac disease completed the validated FR-QoL-29 questionnaire adapted for coeliac disease (FR-QoL-29-Coeliac) and provided demographic and clinical information.

RESULTS

Questionnaires were completed by 138 adults (62% female, mean age 52.3 SD ± 18.6). FR-QoL-29 scores were mean 85.8 (SD ± 23.1). The lowest FR-QoL-29 scores were in the 18-35 year age group (76.6 ± 17.2) compared with the highest in the 56+ age group (92.5 ± 22.3, p = 0.002). Patients with ≥ 4 gastrointestinal (GiS) symptoms had significantly lower FR-QoL-29 scores (77.9 ± 20.7) compared with those with 1-3 GiS (96.7 ± 21, p = 0.0001).

CONCLUSIONS

FRQoL is impaired in coeliac disease and is particularly lower in younger people and those with greater GI symptom burden. Further research should examine the mechanisms that reduce FRQoL in coeliac disease to identify interventions that minimise the burden for patients.

Does Food Habits and Malnutrition Affect Health Perception Among Diabetic Patients? A Mediation and Moderation Analysis

BACKGROUND

The prevalence of diabetes among young individuals has reached concerning levels, posing significant public health risks and exacerbating the economic burden on healthcare systems. The health outcomes of individuals with diabetes are heavily influenced by malnutrition and unhealthy dietary habits, which not only hamper effective blood glucose management but also negatively affect overall health perceptions.

INTRODUCTION

This study analyzes the factors influencing malnutrition, food habits, and health perceptions among diabetic patients.

METHODS

A well-structured questionnaire was designed to collect data. A cross-sectional survey of 503 diabetic patients across various regions in India was conducted. Additionally, structural equation modeling, as well as mediation and moderation analyses, were performed.

RESULTS

The study findings revealed that dietary knowledge, dietitian-led interventions, and economic factors significantly influenced malnutrition and health outcomes. Conversely, nutritional quality did not emerge as a significant predictor.

DISCUSSIONS

The study will help pharmaceutical companies, governments, and healthcare practitioners in marketing dietary supplements, design focused dietary programs, and develop health education campaigns to improve diabetes patients' quality of life. The findings illuminated the critical roles of dietary knowledge, dietitian-led interventions, economic factors, and lifestyle modifications in managing malnutrition and enhancing health outcomes.

CONCLUSIONS

The study demonstrated significant mediation and moderation effects, emphasizing the complex interplay between food habits and malnutrition on health perceptions. However, nutritional quality was not a significant predictor, and the research underscored the necessity of holistic, personalized interventions. This will also help medical marketers in devising their marketing strategies.

Food-related Quality of Life in patients with Inflammatory Bowel Disease: Translation and Validation of the German version of FR-QoL-29

The psychosocial effects of eating and drinking - summarized as food-related quality of life (FR-QoL) - are underexplored in inflammatory bowel disease (IBD). Currently, there is no German instrument to assess FR-QoL in IBD patients. This study aimed to translate the validated English FR-QoL-29 questionnaire into German and evaluate its validity and reliability.A monocentric, cross-sectional study was conducted at a tertiary referral center with IBD patients and healthy controls. Participants completed questionnaires on sociodemographics, disease history, the Malnutrition Universal Screening Tool (MUST), the German Short Health Scale (SHS), and the FR-QoL-29-German. The FR-QoL-29 was translated into German using a forward-backward method. Its reliability and validity was assessed using Pearson correlation coefficients, intraclass correlation coefficients, and Cronbach's α.N=200 IBD patients (Crohn's disease: 61.8%; women: 50.8%; remission: 56.2%) and n=10 healthy controls completed the questionnaires. Overall, 113 IBD patients repeated the questionnaires after an average of six weeks. Significant differences in FR-QoL-29-German sum scores were found between all levels of IBD disease activity, except for remission - mild disease (p = 0.423) and moderate - severe disease (p = 0.999). FR-QoL-29-German scores significantly correlated with age (p = 0.041), disease activity (p < 0.001), MUST (p = 0.015), fecal Calprotectin (p = 0.011) and SHS (p < 0.001). Overall, the FR-QoL-29-German showed excellent internal consistency (Cronbach's α = 0.965) and good test-retest reliability (ICC = 0.85 [95% CI: 0.78-0.89]).The FR-QoL-29-German is a valid and reliable tool for assessing food-related quality of life in German-speaking individuals with IBD.

'Nobody wants to talk about that stuff': a qualitative investigation of the anticipated public perceptions of individuals with Inflammatory Bowel Disease

OBJECTIVE

Little research has explored in-depth qualitative opinions on anticipated public views of Inflammatory Bowel Disease (IBD) among those with the condition, and the potential impact of these views on wellbeing. This study explored the perceptions and reactions anticipated by those with IBD from the public (RQ1), and the impact these anticipated perceptions have on participants' physical and psychological health, and their quality of life (RQ2).

METHOD

Twenty participants (aged 18-56 years) were recruited via Crohn's and Colitis Australia and online IBD support forums. Individual, semi-structured interviews were conducted with participants. To avoid researcher bias, two independent data coders conducted thematic analysis to identify themes and subthemes.

RESULTS

The themes identified by both coders were further examined and reported. Four themes were identified: (1) poor public awareness of IBD; (2) difficulties with disclosure; (3) emotional and social public reactions; and lastly, (4) 'self-exclusion'. Most participants indicated that their physical health and quality of life are not impacted by their anticipated views, however, some participants reported that their psychological health is impacted.

CONCLUSION

This study uncovered the adverse impact of anticipated public views on psychological health. Regarding study implications, self-excluding behaviours should be routinely assessed in clinical practice.

Can Diet Quality Be Associated with Disease Activity in a Prospective Dutch Inflammatory Bowel Disease Cohort?

Background/Objectives: Inflammatory bowel disease (IBD) is characterized by a relapsing-remitting disease course, influenced by dietary factors. This study aims to examine diet quality in IBD patients and investigate its association with disease activity. Methods: In total, 477 participants from a prospective IBD cohort study at two Dutch hospitals were approached to complete a population-specific food frequency questionnaire (GINQ-FFQ) at baseline and after one year. Disease characteristics were assessed at multiple time points. Food-related Quality of Life (FrQoL) was assessed at baseline. Diet quality was measured via the Dietary Inflammatory Index (DII), Mediterranean Diet Score (MDS), Healthy Diet Indicator score (HDI), ultra-processed food intake, and Principal Component Analysis (PCA) to identify dietary patterns. The outcomes were compared to the general Dutch population. Results: In total, 191 participants completed the GINQ-FFQ at baseline, of whom 53 had active disease. Patients in remission had higher FrQoL than patients with active disease (p = 0.020). Diet quality and adherence to specific dietary patterns were not associated with disease activity. However, logistic regression showed a trend toward increased odds of increase in disease activity with an animal protein-rich pattern (OR: 1.479, p = 0.088) and a potential association between the Convenience diet and decreased disease activity (OR: 1.396, p = 0.060). Both the Dutch population and the patient cohort scored poor on all diet quality scores. Conclusions: The current study shows no conclusive evidence of an association between disease activity and both diet quality and dietary patterns in patients with IBD. However, the findings do suggest a possible association between animal protein-rich diets with more disease activity and Convenience-like diets with less disease activity. Furthermore, a similar diet quality was observed in IBD patients and the general Dutch population. Nevertheless, diet quality was generally poor and can be improved.

Association between avoidant/restrictive food intake disorder risk, dietary attitudes and behaviors among Chinese patients with inflammatory bowel disease: a cross-sectional study

BACKGROUND

Restrictive eating behaviors are common among patients with inflammatory bowel disease (IBD), which may may develop nutritional and/or quality of life impairments into avoidant/restrictive food intake disorder (ARFID). The objective of this study is to estimate the prevalence and characteristics of ARFID in Chinese patients with IBD, and to investigate the current perceptions and dietary behaviors of patients with and without ARFID.

METHODS

A cross-sectional study was conducted in gastroenterology clinics of four tertiary hospitals in China. Patients with IBD were asked to complete a structured questionnaire including demographic characteristics, dietary attitudes and behaviors. The diagnosis of ARFID was established using Chinese version of the Nine-Item Avoidant/Restrictive Food Intake Disorder Screen questionnaire.

RESULTS

A total of 483 patients with IBD completed the questionnaires, and 20.3% met clinical criteria for ARFID. The average score of ARFID was 21.9 (interquartile range = 17.0-26.0). Multivariable binary logistic regression results showed that patients with Crohn's disease (OR = 0.483, 95%CI = 0.280-0.835; p = 0.009), being in an active disease state (OR = 0.220, 95%CI = 0.123-0.392; p < 0.001), holding dietary attitudes regarding symptom control (OR = 2.431, 95%CI = 1.299-4.548; p = 0.005), and reporting a specific dietary history (OR = 27.158, 95%CI = 3.679-200.456; p = 0.001) were significant more likely to suffer from ARFID.

CONCLUSIONS

ARFID is a common problem among patients with IBD. The incidence of ARFID is particularly high among patients with Crohn's disease, during relapse, and those who hold restrictive dietary attitudes or have a history of specific diets. Therefore, it is imperative to prioritize routine screening and early identification of ARFID, especially among high-risk populations, in future research and clinical practice.

Italian validation of the IBD-disk tool for the assessment of disability in inflammatory bowel diseases: A cross-sectional multicenter study

INTRODUCTION

IBD-Disk is a simple, easy-to-use, and self-administered analogue visual tool for assessing disability in patients with Inflammatory Bowel Disease (IBD). However, it has not yet been validated in Italian. This study aims to validate IBD-Disk in an Italian cross-sectional multicentre study.

METHODS

This study was conducted in eight IBD centres from February 2023 to October 2023. After forward-backwards translation of IBD-Disk into Italian, patients consecutively completed IBD-Disk (at baseline and after 7 days), IBD-Disability Index (IBD-DI) and IBDQ-32 for quality of life.

RESULTS

We enrolled 767 patients (377, 49,2% CD; 390, 50,8% UC) who completed the IBD-Disk [median score of 30 (IQR=11-52)]. Internal consistency was excellent, with Cronbach's α of 0.92 (95%CI=0.92-0.92). To evaluate the validity, the IBD-Disk was compared with the IBD-DI and IBDQ-32, revealing a significant positive correlation of 0.70 (95% CI=0.66-0.73; p<0.001) and 0.83 (r=0.83, 95% CI=0.80-0.85; p<0.001), respectively. The intraclass correlation coefficient (ICC) was 0.84 (95% CI=0.82-0.86) for test-retest. Female gender, clinically active IBD and the presence of extraintestinal manifestations led to higher IBD-Disk scores.

CONCLUSION

This study validated the IBD-Disk in a large cohort of Italian IBD patients, demonstrating that it is a valid, reliable and responsive tool for quantifying IBD-related disability. This validation facilitates its integration into the daily clinical management of IBD patients.

Factors influencing food-related quality of life in patients with inflammatory bowel disease: A systematic review

BACKGROUND

People diagnosed with Inflammatory bowel disease (IBD) often have severe dietary restrictions and avoidance due to the uncertainty of intestinal symptoms. Inadequate dietary intake may increase the risk of malnutrition and result in impaired food-related quality of life (FRQoL). Few studies investigated factors influencing FRQoL in patients with IBD. This study aimed to synthesize the existing evidence regarding FRQoL among patients with IBD, including the current situation, measurement instruments, and related influencing factors.

METHOD

The comprehensive literature search was conducted in databases including PubMed, Embase, CINAHL, PsycInfo, Cochrane Library, as well as the most commonly used Chinese databases (CNKI, Wanfang and CBM). Studies published between January 2015 and December 2023 on FRQoL in patients with IBD were included. The Joanna Briggs Institute (JBI) critical appraisal checklist was utilized to evaluate the methodological quality of the selected studies.

RESULTS

Finally, only five studies met the inclusion criteria were reviewed, including three cross-sectional studies and two case-control studies. The Food-related quality of life-29 Scale (FR-QoL-29) with a total core of 145 was the most used instrument measuring FRQoL in patients with IBD. The mean scores of FRQoL ranged from 69.9 to 102.3 in adult patients with IBD and 94.3 in children. A diverse range of factors were associated with FRQoL, including socio-demographic, clinical, psychological, diet-related, and nutrient intake factors.

CONCLUSIONS

The main influencing factors of FRQoL among patients with IBD included disease activity status, severe symptoms, history of IBD surgery, negative emotion reaction, and restrictive eating behaviour. Clinicians should work in concert with dietitians, keeping an eye on the disease status, nutrition intake, and restrictive eating habits, assessing FRQoL and providing personalized dietary recommendation for the patients with IBD.

Addressing Nutritional Knowledge Gaps in Inflammatory Bowel Disease: A Scoping Review

This scoping review aims to map the existing literature on nutritional knowledge among people with IBD, identify gaps in current understanding, and provide guidance for future educational interventions. Background: Inflammatory bowel diseases (IBDs) are chronic conditions affecting the gastrointestinal tract, where nutrition plays a crucial role in symptom management. Despite its significance, patient knowledge about proper dietary practices remains limited, with widespread misconceptions potentially leading to suboptimal health outcomes. Methods: This review followed the Arksey and O'Malley framework and adhered to PRISMA 2020 guidelines. A systematic search was conducted in three databases (PubMed, Web of Science, and SCOPUS) for studies published between 2003 and 2024. Only studies involving adults (≥18 years) with IBD and focusing on nutritional knowledge were included. Results: From 1440 records initially identified, 23 studies met the inclusion criteria. The findings highlight that IBD patients often base dietary decisions on personal beliefs rather than evidence-based guidelines, leading to widespread food avoidance and increased risk of malnutrition. Misconceptions such as avoiding dairy, gluten, and fiber without professional advice were prevalent. Educational interventions, including personalized counseling and group sessions, showed the potential to improve nutritional knowledge and symptom management, though their application remains inconsistent across settings. Conclusions: IBD patients face significant gaps in nutritional knowledge, emphasizing the need for structured educational initiatives. A personalized, multidisciplinary approach, integrating dietary education into standard care, is essential to improve symptom control and enhance quality of life. Future research should focus on developing evidence-based interventions tailored to the unique needs of this population.

Food-Related Quality of Life in Inflammatory Bowel Disease: Translation and Validation of Food-Related Quality of Life to the Portuguese Language (FR-QoL-29-Portuguese)

Introduction

Food-related quality of life (FR-QoL) has been shown to be an important patient-reported outcome in inflammatory bowel disease (IBD). We aimed to translate and validate a Portuguese version of the FR-QoL-29.

Methods

This was a case-control cross-sectional study undertaken at a tertiary hospital. After obtaining the original authors' authorization, both forward and backward translations of the original FR-QoL-29 were performed by bilingual researchers. After an IBD expert's revision and the input of a small group of patients, a final version was obtained. Portuguese IBD patients were prospectively recruited from the outpatient clinic of a tertiary hospital and completed the questionnaire at two timepoints (0 and 4 weeks). Reliability (internal consistency, test-retest, and intraclass correlation [ICC]), validity (content and convergent validity, and hypothesis testing using Spearman's correlations), and responsiveness (Student t tests) were analysed.

Results

239 patients (mean age 50.1 [SD = 15.3 years], 56.5% female) and 87 (36.4%) patients answered the questionnaire at the first and second timepoints, respectively; 126 controls answered the questionnaire. Overall, the FR-QoL-29-Portuguese showed excellent internal consistency (Cronbach's α = 0.97) and good test-retest reliability (ICC = 0.78 [95% CI: 0.64-0.85]). FR-QoL moderately correlated with health-related quality of life, measured by the SIBDQ-PT (R = 0.49; p < 0.05). Lastly, the questionnaire revealed appropriate responsiveness when patients reported an overall improvement in general well-being (mean improvement 25.88 [SD = 32.50]; p < 0.05).

Discussion/Conclusions

We present an adaptation and validation of the FR-QoL-29 tool for Portuguese IBD patients. The FR-QoL-29-Portuguese is a reliable and valid tool shown to be responsive to changes in general well-being.

'Eating with Others': planning, developing and optimising a self-management intervention to promote social eating for patients living with and beyond head and neck cancer

INTRODUCTION

After treatment for head and neck cancer (HNC), up to 90% of patients have difficulties eating and drinking. Despite the enormity of challenges explicitly relating to the social dimension of eating, there are limited extant interventions to specifically support social eating, nor any replicable for use in contemporary clinical practice. This study aims to plan, develop and optimise a self-management intervention to promote social eating for patients living with and beyond HNC.

METHODS

This research was intervention development of a self-management 'Eating with Others' resource, guided by the person-based approach (PBA) framework. Initially, a systematic review was conducted, with 24 included studies exploring HNC patients' social eating experiences, followed by thematically analysed qualitative interviews with patients (n = 14), family members (n = 12) and healthcare professionals (n = 13). Alongside this data, iterative input was sought from an advisory group (n = 22) to culminate in an intervention prototype. The intervention prototype was iteratively user-tested over three cycles for usability and acceptability, using think-aloud interviews (n = 10).

RESULTS

A patient-centred, evidence-based and theory-driven self-management resource, entitled 'Eating with Others', was designed to promote social eating for patients with HNC. Sections included the benefits of social eating; the impact of HNC on social eating, strategies and reflective activities to overcome social eating barriers; and the use of a social eating card for restaurants. The think-aloud interviews revealed that the resource was appropriate and acceptable for patients with HNC.

CONCLUSION

The systematic and iterative PBA intervention development framework enabled empirical research findings, relevant theory and extensive advisory group involvement to design an acceptable self-management social eating intervention for patients living with and beyond HNC. Mixed-methods evaluation is required to determine feasibility in clinical practice.

Food-related quality of life driven by hypervigilance and anxiety around eating in organic gastrointestinal conditions

BACKGROUND

Food-related quality of life (FRQoL) measures the impact of diet, eating behaviours and food-related anxiety on quality of life. Patients often view food and eating as central to symptom management. This is the first study to examine FRQoL in patients with inflammatory bowel disease, celiac sprue, achalasia and eosinophilic oesophagitis.

METHODS

A total of 289 adults aged ≥18 years completed self-report measures evaluating the use of dietary treatment, FRQoL and other psychosocial outcomes. Principal component factor analysis evaluated potential subscales within the Food-Related Quality of Life Scale (FRQoL-29), to date validated only with a total score. Univariate analyses investigated differences in FRQoL based on diagnosis, whereas correlations and hierarchical regression identified relationships between FRQoL and psychosocial outcomes.

RESULTS

Factor analysis revealed four subscales within the FRQoL-29, with hypervigilance around eating being the primary driver in total score. Patients reported substantial impacts of FRQoL, with those not using diet therapy scoring significantly higher for FRQoL than those on a diet with and without the support of a registered dietitian (RD). Both social (r = 0.41, p < 0.001) and physical (r = 0.31, p < 0.001) domains of health-related quality of life were higher in patients with greater FRQoL.

CONCLUSION

FRQoL is significantly degraded in patients with organic gastrointestinal illness diseases, and hypervigilance around food appears to contribute most to this. Use of dietary treatment and meeting with an RD were associated with lower FRQoL, though it is unclear if patients sought RD assistance before FRQoL declined. Future studies on the relationship between dietary treatment, RD support and FRQoL are warranted.

Dietary management of irritable bowel syndrome: considerations, challenges, and solutions

Diet is a cornerstone in the management of irritable bowel syndrome (IBS). There is evidence of efficacy across the spectrum of dietary management strategies, including some supplements (eg, specific fibres), foods, and whole diets (eg, a diet low in fermentable oligosaccharides, disaccharides, monosaccharides, and polyols [known as the low-FODMAP diet]). Whole-diet interventions, in particular those that restrict intake, can be challenging to deliver effectively and safely. Factors to consider include patient demographics, food cost and availability, and the acceptability of dietary management and its impact on food-related quality of life. There is concern regarding a potential role of restrictive whole-diet interventions in eating disorder risk. Optimal approaches to delivering dietary management in the health-care setting are unclear. The aim of this Review is to summarise the clinical evidence for the dietary management of IBS; to discuss the challenges, burdens, and risks of dietary management; and to propose how these challenges, burdens, and risks should be mitigated and minimised in clinical practice.

The Crohn's Disease Exclusion Diet: A Comprehensive Review of Evidence, Implementation Strategies, Practical Guidance, and Future Directions

Dietary therapy is increasingly recognized for the management of Crohn's disease (CD) over recent years, including the use of exclusive enteral nutrition (EEN) as first-line therapy for pediatric CD according to current guidelines. The Crohn's disease exclusion diet (CDED) is a whole-food diet designed to reduce exposure to dietary components that are potentially pro-inflammatory, mediated by negative effects on the gut microbiota, immune response, and the intestinal barrier. The CDED has emerged as a valid alternative to EEN with cumulative evidence, including randomized controlled trials, supporting use for induction of remission and possibly maintenance in children and adults. We gathered a group of multidisciplinary experts, including pediatric and adult gastroenterologists, inflammatory bowel diseases (IBD) expert dietitians, and a psychologist to discuss the evidence, identify gaps, and provide insights into improving the use of CDED based on a comprehensive review of CDED literature and professional experience. This article reviews the management of CDED in both children and adults, long-term aspects of CDED, indications and contraindications, selecting the best candidates, identifying challenges with CDED, globalization, the role of the multidisciplinary team, especially of dietitian, and future directions. We concluded that CDED is an established dietary therapy that could serve as an alternative to EEN in many pediatric and adult cases, especially with mild to moderate disease. In severe disease, complicated phenotypes, or with extraintestinal involvement, CDED should be considered on a case-by-case basis, according to physician and dietitians' discretion. More studies are warranted to assess the efficacy of CDED in different scenarios.

'Food doesn't control me anymore!' psychosocial experiences during dietary management in adults with inflammatory bowel disease: A qualitative study

AIMS

To explore the psychosocial experiences during dietary management among Chinese adults with inflammatory bowel disease.

DESIGN

Qualitative phenomenological design.

METHODS

Eighteen adults diagnosed with inflammatory bowel disease for more than 6 months were recruited using purposive sampling from June to December 2023. Two trained researchers used van Manen's approach to analyse the data.

RESULTS

The three themes with multiple subthemes emerged: facing the unknown: at a loss and aggrieved, trying to cope: uncertain and distressed, and growing in adaptation: relieved and transcendent. The first theme included unknown relapses, overlooking diet management and the absence of dietary rules. The second theme showed different coping situations, like complex dietary information and ever-closing worlds. The third theme explores how participants adapted to disease and their eating patterns.

CONCLUSION

The psychosocial experiences during dietary management are complex. The accumulation of diet-related experience, acceptance of illness and social support facilitate patients in overcoming negative emotions and adhering to dietary management.

IMPLICATIONS FOR THE PROFESSION AND PATIENT CARE

Nurses should provide tailored dietary guidance and appropriate psychological interventions to promote healthy eating in patients.

IMPACT

This study may enhance healthcare professionals' understanding, particularly those in China, of the diet-related experiences among patients.

The disease recurrence perception scale for patients with inflammatory bowel disease: Instrument development and cross-sectional validation study

Disease recurrence perception plays a key role in disease management and subsequent disease recurrence prevention. However, there are no specific tools for assessing disease recurrence perception in patients with inflammatory bowel disease (IBD) characterized by alternating remission and recurrence. To develop and validate an instrument for measuring disease recurrence perception of patients with IBD, the study was conducted in two steps: (1) instrument development and (2) psychometric tests. A total of 623 patients with IBD participated in the study. The common sense model of illness self-regulation (CSM) was used as a framework for instrument development. The administered version contained 48 items intended to be relevant to at least one of the six dimensions of the model. Based on preliminary analyzes, 12 items were deleted leaving 36 items for more detailed psychometric and factor analyzes. The Cronbach's alpha coefficient of the total 36-item instrument was 0.915. The content validity indexes at item and scale levels were satisfactory. The test-retest reliability of the total instrument was 0.870. Exploratory principal components analysis (n = 278) was used to identify six components congruent with intended CSM constructs that accounted for 62.6% of total item variance. Confirmatory factor analysis (n = 345) found acceptable fit for the six factor measurement model (χ2/df = 1.999, GFI = 0.846, NFI = 0.855, IFI = 0.922, TLI = 0.910, CFI = 0.921, RMSEA = 0.054). Overall, the DRPSIBD demonstrated satisfactory reliability and validity to warrant further development as a measure of disease recurrence perception of patients with IBD.

Experience of diet in patients with inflammatory bowel disease: A thematic synthesis of qualitative studies

AIM

To synthesise the dietary expesriences of patients with inflammatory bowel disease by reviewing relevant qualitative studies.

BACKGROUND

Diet plays a crucial role in the development and progression of inflammatory bowel disease (IBD). There is no specific diet that can be recommended for all patients. We conducted a synthesis of qualitative studies to gain a comprehensive understanding of the dietary management experience of patients with IBD, aiming to provide better dietary guidance in the future.

DESIGN

A qualitative synthesis was conducted following the Thomas and Harden method and reported following the ENTREQ statement.

METHODS

Qualitative studies were systematically searched in five electronic databases: PubMed, PsycINFO, Embase, CINAHL, and Web of Science. There was no time limit for publication, and all database searches were up to 10 May, 2023. The Joanna Briggs Institute Qualitative Assessment and Review Instrument was utilised to appraise the quality of the included studies. Data for inclusion in articles were extracted and analysed using a thematic synthesis method.

RESULTS

Six studies involving 119 patients were eventually included. The studies were conducted in six different countries. Four major themes were identified: the diet of patients with IBD is completely different from the normal one; manage symptoms and live with the disease by modifying diet; psychological adjustment to eating (be frustrated; worried and afraid; feel ashamed; growth and resilience); barriers and challenges (barriers from perceived social support; conflicts between diet and nutrition; challenges from food hedonism and cravings).

CONCLUSIONS

Patients with IBD highlighted the distinction between their diet and the normal diet. Dietary modifications were used as a way to manage symptoms and live with the disease. In addition to physical symptoms, patients experienced diet-related psychological changes. Dietary modifications in patients with IBD encounters difficulties and challenges, necessitating prompt guidance and intervention. (1) The implementation of dietary modifications in patients with IBD encounters numerous obstacles and complexities, necessitating prompt guidance and intervention.

The body as an obstacle and the "other". How patients with chronic inflammatory bowel diseases view their body, self and the good life

BACKGROUND

Treatment of chronic inflammatory bowel disease (IBD) aims to improve patients' quality of life and the extent of treatment success is measured via patient reported outcomes (PROs). However, questionnaires used to collect PROs often include scales that are not specific to IBDs. Improving these scales requires a deeper understanding of patients' lived experience. With this study we give first insights and develop hypotheses on how patients with IBDs experience their body and self and how they adjust their life plans in the context of precision medicine (PM). The guiding question is to understand what they need to achieve a good life, while facing their disease.

METHODS

We developed a conception of the "good life" that draws on Philippa Foot's "naturalized" approach and distinguishes six different dimensions that are relevant for a good life. This conception guided us as we conducted 10 qualitative interviews with patients suffering from IBD who were in precision medicine clinical research settings. The interviews aimed to gain insights for answering our research question: How do body experiences affect the good life of patients with IBD? We analyzed the interviews with interpretative phenomenological analysis (IPA).

RESULTS

Five group experiential themes emerged: (i) Life options and plans, (ii) other people's responses, (iii) strategies to deal with others' responses, (iv) perception of the body and self, and (v) perception of life as good despite suffering. We report here on three of them (i, iv and v), which are primarily relevant for evaluating the outcomes of PM care. Whereas with "life options and plans (i)," our study predominantly confirmed previous research, with "perception of the body and self (iv)," we found that some of the patients changed their relationship to their body and themselves. They perceived the body or the disease as the "other" and their self appears divorced from their own body. Although this might be an avoidance strategy patients use to assign responsibility for their condition and its "disgusting" symptoms to the "other," it is important to include it in patient reported outcome (PRO) assessments.

CONCLUSIONS

We conclude with the insight that the multi-dimensional approach based on Foot's concept of a good life is well-suited as a basis for investigating the quality of life of people with IBD. Interviews based on this concept produced results that go beyond the understanding of health-related quality of life (HRQoL). Additionally, we offer some considerations about patients' opportunities for achieving a good life and suggestions for further developing patient reported outcome scales.

A Comprehensive Review of Dietary Approaches in Maintaining Remission of Inflammatory Bowel Diseases in Adults

Inflammatory bowel disease (IBD) poses significant challenges in its management, encompassing a spectrum of conditions from Crohn's disease to ulcerative colitis. Dietary interventions have emerged as integral components of the multidisciplinary approach to IBD management, with implications ranging from disease prevention to treatment of active manifestations and addressing complications such as malnutrition. While dietary interventions show promise in improving outcomes for some patients with IBD, there is no consensus in the existing literature regarding remission maintenance in those patients. Furthermore, many patients explore dietary modifications often guided by anecdotal evidence or personal experiences and this could lead to malnutrition and decreased quality of life. This comprehensive review synthesizes existing literature to elucidate the complex interplay between diet and IBD, offering insights into the efficacy and safety of various dietary modalities in maintaining disease remission. It also highlights the importance of patient education in navigating dietary choices and potential risks associated with food avoidance, including the heightened risk of micronutrient deficiencies. Furthermore, it emphasizes the pivotal role of a multidisciplinary care team comprising clinicians and dietitians in providing personalized dietary guidance tailored to individual patient needs and goals. By synthesizing the latest evidence and providing insights into both the potential benefits and risks of dietary interventions, this review could be used as a resource for healthcare professionals and patients alike in navigating the complex landscape of dietary management in IBD.

Food-Related Quality of Life Is Impaired in Latinx and Non-Latinx Patients With Inflammatory Bowel Disease

Background and Aims

Anxiety over food choices and symptoms related to food consumption diminish quality of life (QoL) in inflammatory bowel disease (IBD) patients. However, the specific factors that impact QoL among IBD patients remain unclear. In this study, we analyzed the relationships of demographic and disease factors with food-related QoL (FRQoL) in a large, diverse US cohort of IBD patients.

Methods

In this cross-sectional analysis of 1108 IBD patients aged ≥18 years, we measured FRQoL with the 29-item Food-Related Quality of Life Questionnaire (FR-QoL-29) and disease activity with the Harvey-Bradshaw index in Crohn's disease (CD) patients or the Simple Clinical Colitis Activity Index in ulcerative colitis (UC) patients. Latinx immigrants completed a Spanish translation of the FR-QoL-29. A subset of patients had colonoscopy and inflammatory marker data available. We used univariate, multivariate, and subgroup analyses to examine the factors that influence FRQoL.

Results

In our cohort, 55% of IBD patients self-identified as Latinx. Latinx and non-Latinx patients had similar FR-QoL-29 scores. Female patients had significantly lower FRQoL than male patients (P = .001). Increasing age and IBD duration correlated with higher FRQoL (P < .0001). In UC patients, higher Simple Clinical Colitis Activity Index scores (P < .0001), higher Mayo scores (P = .0009), and longer disease duration (P = .03) predicted significantly lower FRQoL. Disease activity and FRQoL were not significantly related in CD patients.

Conclusion

This is the largest study to date to examine FRQoL in American IBD patients, and the first to include Latinx patients. Disease-related factors had a greater impact on FRQoL than ethnicity. Clinical and endoscopic disease activity had a more detrimental impact on FRQoL in UC than in CD. Diet intervention studies are needed to alleviate symptoms and improve FRQoL in the IBD population.

When dietary modification turns problematic in patients with esophageal conditions

BACKGROUND

Patients with chronic illness affecting the esophagus often modify their eating habits to manage symptoms. Although this begins as a protective strategy, anxiety around eating can become problematic, and lead to poor outcomes. We administered a survey to examine the factors associated with problematic eating behaviors in patients who have reflux and difficulty swallowing (esophageal dysphagia).

METHODS

In total, 277 adult patients aged above 18 diagnosed with achalasia, eosinophilic esophagitis, and gastroesophageal reflux completed an online survey: (1) demographic and disease information; (2) reflux and dysphagia severity (3) eating behaviors, as measured by a study-specific, modified version of the Eating Disorder Questionnaire (EDE-Q) for patients with esophageal conditions; and (4) Food related quality of life (FRQOL). Descriptive statistics, one-way ANOVA, and Pearson's correlations evaluated the sample data and a hierarchical linear regression evaluated predictors of problematic eating behaviors.

KEY RESULTS

Problematic eating behaviors were associated with reflux severity, dysphagia severity, symptom anxiety, and hypervigilance, and negatively associated with FRQOL. While reflux and dysphagia severity predicted greater problematic eating, symptom anxiety explained more of these behaviors. Although hypervigilance and anxiety also predicted poorer FRQOL, problematic eating was the largest predictor.

CONCLUSION & INFERENCES

Problematic eating behaviors are associated with increased symptom severity and symptom anxiety, and diminished FRQoL. Symptom anxiety, rather than symptom severity, appears to be a driving factor in problematic eating behaviors. Interventions aimed at diminishing symptom anxiety may be useful in reducing problematic eating behaviors in patients with gastrointestinal symptoms.

Food-Related Quality of Life and Its Predictors in Inflammatory Bowel Disease

BACKGROUND

Inflammatory bowel disease (IBD) is associated with dietary restrictions and food- and drink-driven daily life limitations. Food-related quality of life (FR-QoL) is still an under-addressed issue in IBD.

AIM

We aimed to study determinants of FR-QoL in an IBD cohort, namely objective measures of disease activity.

METHODS

A cross-sectional case-control study was conducted in a Tertiary Hospital, including adult patients with IBD (cases) and blood donors or subjects referred for colorectal polypectomies (controls). Participants answered an anonymous multimodal questionnaire including sociodemographic and clinical data, the validated FR-QoL-29, and the SIBDQ tools. Patients' disease activity was previously assessed by a physician using symptom-based scores and biomarkers (Harvey-Bradshaw index, partial Mayo score, fecal calprotectin).

RESULTS

A total of 239 patients with IBD and 126 controls were included. Patients with active disease had poorer FR-QoL than patients in remission (80.0 [56.0-99.0] vs. 103.5 [81.0-129.9], p < 0.001). Still, patients with IBD had significantly lower FR-QoL compared with controls (99.0 [76.0-126.0] vs. 126.0 [102.8-143.0], p < 0.001), irrespective of disease activity. FR-QoL correlated with health-related quality of life, measured by SIBDQ (r = 0.490, p < 0.001), and was significantly impaired by patients' depressive humor (84.0 [61.0-112.0] vs. 108.0 [88.0-130.5], p < 0.001). Globally, FR-QoL compromise was mostly related to persistent worries about food, concerns about food-related symptoms, and life disruption due to eating and drinking.

CONCLUSIONS

Patients with IBD showed significant FR-QoL impairment, irrespective of disease type and activity. Related psychosocial factors, such as the patient's affective status and fear around eating, warrant a need for a multidisciplinary approach to IBD, including tailored nutritional counseling.

Crohn's disease

Crohn's disease is a chronic inflammatory disease of the gastrointestinal tract that might lead to progressive bowel damage and disability. The exact cause of Crohn's disease is unknown, but evidence points towards multifactorial events causing dysregulation of the innate immune system in genetically susceptible people. Commonly affecting the terminal ileum and proximal colon, Crohn's disease inflammation is often discontinuous and patchy, segmental, and transmural. Identification of characteristic findings on ileocolonoscopy and histology remains the diagnostic gold standard, but complete assessment involves laboratory abnormalities, including micronutrient deficiencies, cross-sectional imaging to identify transmural disease extent, severity and complications, and a psychosocial assessment. Treatment strategies for patients with Crohn's disease now go beyond achieving clinical remission to include deeper targets of endoscopic healing and consideration of adjunctive histological and transmural targets to alter disease progression potentially further. The use of early effective advanced therapies and development of therapies targeting alternative novel pathways with improved safety profiles have resulted in a new era of healing in Crohn's disease management. Future combination of advanced therapies with diet or other biological drugs and small molecules, together with improvements in tight control monitoring tools and predictive biomarkers might continue to improve outcomes for patients with Crohn's disease.

YouTube as a Source of Information for Food, Diet-Related Items, and Advisory Comments for the Management of Inflammatory Bowel Disease

BACKGROUND

Patients with inflammatory bowel disease (IBD) often use the Internet to seek information beyond that received from healthcare professionals. This study assessed the perceptions of YouTube presenters on the role of diet in the management of IBD.

METHODS

Videos discussing dietary aspects (food, diet-related items, and advisory comments [FODRIACs]) in the management of IBD were included. The perceptions of presenters toward each FODRIAC were labeled as positive, negative, or neutral/intermediate, and FODRIACs were classified according to their underlying role in the management of IBD (eg, symptom management, gut inflammation). Subgroup analysis was performed by type of video presenter (patients vs healthcare professionals), type of IBD (Crohn's disease vs ulcerative colitis), and reporting of scientific evidence supporting presenters' perceptions.

RESULTS

We identified 122 FODRIACs within 160 videos. Patient videos received a higher number of likes (median 85 [interquartile range, 35-156]) than healthcare professional videos (median 44 [interquartile range, 16-1440]) (P = .01). Scientific evidence was cited in 2 (3%) of 76 patient videos compared with 25 (35%) of 71 healthcare professional videos (P < .001). Positive perceptions were expressed about avocadoes, salmon, bananas, white bread, and rice, whereas negative perceptions were reported for processed, high-fat and high-sugar foods and carbonated drinks. Fewer negative perceptions were expressed in videos supported by scientific evidence than in videos that lacked evidence (scientific: 4 positive, 0 negative vs nonscientific: 7 positive, 20 negative; P = .01).

CONCLUSIONS

We have identified FODRIACs proposed as beneficial or detrimental in the management of IBD. The effect this information has on dietary practice as patients with IBD self-manage their condition needs further exploration.

A scoping review of the dietary information needs of people with inflammatory bowel disease

AIMS

This review aimed to explore and describe the dietary information needs of individuals with inflammatory bowel disease and sources of information.

METHODS

A scoping review of English language articles and grey literature, using electronic databases with a predefined search strategy was undertaken. Data were synthesised based on the identified variables (e.g. dietary information needs and sources of dietary information) corresponding to the aims of this review.

RESULTS

Forty-six studies were included, reporting data from 7557 people with inflammatory bowel disease, of which 58.6% had Crohn's disease and 60.1% were males. Dietary information was rated very important and appeared to be influenced by the disease course. The need to discuss it is heightened at important stages, namely diagnosis and relapse. Dietary information was described broadly and included advice about foods to avoid and dietary advice for symptoms management. No major differences were noted in the dietary information needs of people with Crohn's disease compared to ulcerative colitis. The main sources of dietary information were the gastroenterologist (36%-98%), the internet (9%-60%) and non-dietetic professionals (84.7%).

CONCLUSION

This review highlights limited literature describing the dietary information needs of people with inflammatory bowel disease. Importantly, the limited access to specialised dietary advice for this cohort is concerning. Future studies are required to explore not only the nuances in the needs of those with active disease and in remission, but to further understand issues of access to specialised dietary advice to provide holistic person-centred care desired by this cohort.

Factors influencing the quality of life in inflammatory bowel disease: A comprehensive review

Inflammatory bowel disease (IBD) is a group of chronic relapsing disorders, including Crohn's disease (CD) and ulcerative colitis (UC), which affects an increasing number of people worldwide. In the last few decades, the scientific world has witnessed many developments in IBD management by controlling debilitating symptoms and remaining in remission for more protracted periods. Even so, we still have a large population suffering from active IBD. An individual's quality of life (QoL) can be severely affected by IBD, like any other chronic illness. In this article, we have reviewed factors influencing the QoL in IBD patients, including chronic pain, diet, physical activity, and psychological factors like depression, anxiety, and stress symptoms. We also discussed the mechanisms of diet-microbial-immune system interaction, currently available dietary therapies for active CD and UC, and early psycho-social interventions that can reduce the disease burden and improve QoL in IBD patients.

Difficulties in eating out of home while diagnosed with inflammatory bowel disease: A qualitative interview study from China

BACKGROUND

Meeting healthy dietary needs while eating out can be a challenging experience for adults with inflammatory bowel disease. This study examined the barriers experienced by adults with inflammatory bowel disease (IBD) when eating out.

OBJECTIVE

This study aimed to explore the perceptions of people with IBD on eating out barriers.

DESIGN

A qualitative study among individuals affected by IBD was conducted through semi-structured interviews.

RESULTS

Sixteen adults from China were diagnosed with IBD between 6 months and 20 years prior to the study. They were recruited from four tertiary care hospitals in Nanjing, China. The participants completed a semi-structured interview between April and September 2022. Self-perceived difficulties with eating and drinking when eating out were varied. After thematic analysis of the data, five main themes emerged: limited access to healthy and hygiene food; no pleasure of food enjoyment; financial strain; not feeling loved, supported or understood; and coping strategies for not meeting demand.

CONCLUSIONS

This study highlights the various barriers encountered by patients with inflammatory bowel disease when eating out. These findings will help people with IBD to encourage the formation of targeted health and well-being-related interventions. Knowledge of nutrition and diet should be provided in education and training programs administered to IBD.

Weight loss from diagnosis of Crohn's disease to one year post-diagnosis results in earlier surgery

Malnutrition might play a key role in the prognosis of patients with Crohn's disease (CD). The aim of this study was to explore the impact of weight loss from diagnosis of CD to one-year post-diagnosis on disease prognosis in terms of surgery. Patients who were diagnosed with CD at Samsung Medical Center between 1995 to 2020 were included in this study. The study defined the "group with weight loss" as patients with weight loss in one year after diagnosis and the "group without body weight loss" as patients without weight loss in one year after diagnosis. Their data such as demographics, laboratory findings, and medical interventions were collected retrospectively. The primary outcome was confirmation of the difference in the incidence of surgery associated with CD between the group with weight loss and the group without body weight loss. We further analyzed factors associated with surgery outcomes. A total of 165 patients were analyzed in this study. Forty-one patients (24.8%) had body weight loss whereas 124 patients (75.2%) had no body weight loss. Body change at one year showed no significant association with direct surgical incidence. However, the patients with weight loss tended to undergo surgery earlier than patients without body weight loss. Among factors associated with outcomes of Crohn's surgery, the albumin was the only significant factor. Patients with weight loss had no statistically significant increase in the risk of surgery than patients without weight loss, although they tended to undergo surgery earlier than patients without body weight loss. A prospective study is needed to determine serial body weight changes during follow-up for patients with CD.

Risk of avoidant/restrictive food intake disorder in patients with inflammatory bowel disease: predictive value of disease phenotype, disease activity and food literacy

BACKGROUND

Avoidant/Restrictive Food Intake Disorder (ARFID) is a newly described eating disorder. Adequate levels of food literacy allow individuals to have adequate food choices. This study aimed to assess the prevalence of ARFID and the level of food literacy in patients with inflammatory bowel disease (IBD) and to analyse the correlation between ARFID and food literacy.

METHOD

This cross-sectional study screened for ARFID and assessed food literacy levels in patients with IBD attending four tertiary hospitals in China. ARFID risk was measured using the Nine Item Avoidant/Restrictive Food Intake Disorder Screen (NIAS). Food literacy was assessed using the Food Literacy Evaluation Questionnaire (Chinese version, FLEQ-Ch).The relationship between individual NIAS scores and food literacy variables was analysed to assess which food literacy aspect is positively or negatively associated with NIAS scores. Stepwise linear regression analysis was performed to identify the possible predictors of NIAS scores in patients with IBD.

RESULT

A total of 372 IBD subjects completed the NIAS and FLEQ-Ch. The overall mean NIAS scores for the IBD cohort was 28.16 ± 8.03 (p < 0.01), and of the 372 participants, 123 (32.5%) had positive ARFID risk scores (≥ 10 NIAS-picky eating, ≥ 9 NIAS-poor appetite, and ≥ 10 NIAS-fear of negative consequences).The NIAS scores were inversely associated with food literacy levels (β =  - 0.299; p < 0.01).Disease phenotype, disease activity, and food literacy in patients with IBD provided valuable predictive insights for avoiding positive outcomes in ARFID.

CONCLUSION

This study shows that the risk of ARFID in the cohort of patients with IBD is associated with their inadequate food literacy levels. Therefore, this study supports the notion that patients with IBD should be assessed for food literacy regardless of whether they are currently diagnosed with ARFID. Specifically, for early identification of those at risk for ARFID in IBD, disease phenotype, disease activity, and food literacy should be routinely considered in clinical practice.The food literacy awareness of patients must be investigated and improved to predict the risk occurrence of ARFID and encourage healthy eating behaviour.

Current state of dietetic services for inflammatory bowel disease patients in New Zealand: an observational study

AIM

Nutritional therapies for inflammatory bowel disease are increasingly recommended. This study aimed to gain insight from patients, dietitians and gastroenterologists into inflammatory bowel disease dietetic care in New Zealand.

METHODS

Mixed-methods surveys were developed and then distributed online to patients with inflammatory bowel disease and dietitians and gastroenterologists that care for patients with inflammatory bowel disease. Quantitative survey data were analysed using nonparametric statistical tests. Qualitative survey data were analysed using thematic analysis.

RESULTS

Responses were received from 406 inflammatory bowel disease patients, 79 dietitians and 40 gastroenterologists. Half of the patients (52%) had seen a dietitian for nutrition advice. Patients more likely to have seen a dietitian were/had: Crohn's disease (p = 0.001), previous bowel surgery (p < 0.001), younger (p < 0.001) or receiving biologic therapy (p = 0.005). Two-thirds (66%) of patients found the dietitian advice at least moderately useful. A common theme from patient comments was that dietitians needed better knowledge of inflammatory bowel disease. Almost all (97%) gastroenterologists reported that their inflammatory bowel disease patients ask about nutrition; 57% reported that there were inadequate dietitians to meet patient needs. Over 50% of dietitians saw inflammatory bowel disease patients infrequently and 39% were not confident that their knowledge of the nutritional management of inflammatory bowel disease was current. Dietitians desired greater links with the inflammatory bowel disease multidisciplinary team.

CONCLUSION

Current inflammatory bowel disease dietetic services in New Zealand are inadequate. Standardised care, increased resourcing, dietitian training in inflammatory bowel disease, and stronger links with the multidisciplinary team are suggested to improve services.

Perceived dietary intolerances, habitual intake and diet quality of patients with an ileoanal pouch: Associations with pouch phenotype (and behaviour)

BACKGROUND AND AIMS

Ileoanal pouch patients frequently attribute pouch-related symptoms and pouchitis with diet. We aimed to assess perceived food intolerance and habitual dietary intake and their relationship with pouch indication, symptoms and current or history of pouchitis.

METHODS

In this cross-sectional study, patients with an ileoanal pouch completed a dietary intolerance and a food frequency questionnaire, that specifically quantifies habitual intake of FODMAPs. Perceived dietary intolerance rates, nutrient intake and diet quality, and their differences based on pouch indication, symptom, and current or history of pouchitis were assessed. Associations between intolerances and intake, and between dietary intake with pouchitis risk were analysed using univariable and multivariable regression analysis.

RESULTS

Of the 58 (10 FAP and 48 UC) patients with complete data, 81% of UC and 80% of FAP patients reported dietary intolerances. Overall diet quality was good. Differences in dietary intake were limited to a few food groups. Patients with a history of pouchitis had a lower intake of fruits (p = 0.03) and nuts (p = 0.004). Patients with current pouchitis had a lower intake of nuts (p = 0.02). On multivariable logistic regression, intake of dietary fibre was associated negatively [OR 0.68(95%CI:0.51-0.92)] and of non-digestible oligosaccharides positively with pouchitis history [OR 5.5(95% CI:1.04-29.1)].

CONCLUSIONS

In patients with an ileoanal pouch, perceived dietary intolerances are common but had minimal impact on nutritional adequacy and diet quality. Negative associations of the intakes of fruits, nuts and dietary fibre and positive association with non-digestible oligosaccharides with a history of pouchitis require further study to inform dietary recommendations.

Dietary Behaviors and Beliefs in Patients with Inflammatory Bowel Disease

INTRODUCTION

Due to a lack of clear dietary guidelines, patients with inflammatory bowel disease (IBD) self-impose dietary restrictions based on their own nutritional experiences. The aim of this study was to investigate dietary perceptions and behavior in IBD patients.

MATERIALS AND METHODS

A total of 82 patients (48 with Crohn's disease and 34 with ulcerative colitis) participated in this prospective, questionnaire-based study. Based on a literature review, the questionnaire was developed to investigate dietary beliefs, behaviors and food exclusions during IBD relapses and remission.

RESULTS

The majority of patients (85.4%) believed that diet can be a trigger factor for IBD relapses, and 32.9% believed that diet initiates the disease. The majority of patients (81.7%) believed that they should eliminate some products from their diets. The most often-pointed-out products were spicy and fatty foods, raw fruits and vegetables, alcohol, leguminous foods, cruciferous vegetables, dairy products and milk. Most patients (75%) modified their diets after diagnosis, and 81.7% imposed food restrictions to prevent IBD relapses.

CONCLUSIONS

The majority of patients avoided certain foods during relapses as well as to maintain remission of IBD, basing this on their own beliefs, inconsistently with current scientific knowledge. Patient education should be a key determinant in IBD control.

Exclusive Enteral Nutrition for the Treatment of Pediatric Crohn's Disease: The Patient Perspective

Crohn's disease (CD) is a chronic, incurable and relapsing disease involving any part of the gastrointestinal tract and exclusive enteral nutrition (EEN) is first-line therapy. Few studies have examined the patient experience of EEN. The aim of this study was to assess the child' s experiences of EEN, to identify problematic themes and understand the child's mindset. Children with CD who previously completed EEN were recruited to complete a survey. All data were analyzed using Microsoft Excel and reported as N (%). Forty-four children (mean age 11.3 years) consented to participate. Sixty-eight percent of children reported limited formula flavors as the most challenging aspect and 68% of children identified 'support' to be important. This study highlights the psychological impact of chronic disease and its therapies on children. Providing adequate support is essential to insure EEN is successful. Further studies are required to determine psychological support strategies for children taking EEN.

The Reliability and Quality of Short Videos as a Source of Dietary Guidance for Inflammatory Bowel Disease: Cross-sectional Study

BACKGROUND

Dietary management is considered a potential adjunctive treatment for inflammatory bowel disease (IBD). Short-video sharing platforms have enabled patients to obtain dietary advice more conveniently. However, accessing useful resources while avoiding misinformation is not an easy task for most patients.

OBJECTIVE

This study aimed to evaluate the quality of the information in IBD diet-related videos on Chinese short-video sharing platforms.

METHODS

We collected and extracted information from a total of 125 video samples related to the IBD diet on the 3 Chinese short-video sharing platforms with the most users: TikTok, Bilibili, and Kwai. Two independent physicians evaluated each video in terms of content comprehensiveness, quality (rated by Global Quality Score), and reliability (rated by a modified DISCERN tool). Finally, comparative analyses of the videos from different sources were conducted.

RESULTS

The videos were classified into 6 groups based on the identity of the uploaders, which included 3 kinds of medical professionals (ie, gastroenterologists, nongastroenterologists, and clinical nutritionists) and 3 types of non-medical professionals (ie, nonprofit organizations, individual science communicators, and IBD patients). The overall quality of the videos was poor. Further group comparisons demonstrated that videos from medical professionals were more instructive in terms of content comprehensiveness, quality, and reliability than those from non-medical professionals. Moreover, IBD diet-related recommendations from clinical nutritionists and gastroenterologists were of better quality than those from nongastroenterologists, while recommendations from nonprofit organizations did not seem to be superior to other groups of uploaders.

CONCLUSIONS

The overall quality of the information in IBD diet-related videos is unsatisfactory and varies significantly depending on the source. Videos from medical professionals, especially clinical nutritionists and gastroenterologists, may provide dietary guidance with higher quality for IBD patients.

Personalized Dietary Regimens for Inflammatory Bowel Disease: Current Knowledge and Future Perspectives

Inflammatory bowel diseases (IBD) are chronic and incurable conditions of the gastro-intestinal tract with an increasing incidence and prevalence worldwide. Common symptoms are abdominal pain, diarrhea, and weight loss. Despite recent advances in medical management, many patients fail to achieve clinical remission and healing of the mucosa of the bowel. The cause is thought to involve an inappropriate reaction of the immune system, the microbiome and the environment in genetically susceptible individuals, leading to chronic bowel inflammation. Evidence is emerging that diet is a key environmental factor that might influence disease onset and course, and therefore may become a therapeutic strategy to mitigate inflammation and symptoms. Since IBD is a heterogeneous disease on a clinical and a molecular level, personalizing dietary advice could be the crucial factor to achieve long-lasting changes in dietary behaviors that could not only improve nutritional status but also tackle gut inflammation and abdominal symptoms on an individual level. In this review, we first discuss different aspects of personalized nutrition, namely the level, focus, and scope of personalized dietary regimens. Then, we provide a framework for the different goals of nutritional therapy in IBD and current evidence for personalized dietary approaches. Lastly, we discuss the need for adequate trial designs, access to the right data types and the bioinformatic tools that are necessary to develop algorithms that will allow us to move from general "healthy eating" advice to truly personalized nutritional plans for the individual IBD patient.

The impact of Inflammatory Bowel Disease related fatigue on Health-Related Quality of Life: a qualitative semi-structured interview study

Background

Fatigue is a frequently reported symptom of Inflammatory Bowel Disease (IBD), having a negative impact on Health-Related Quality of Life (HRQoL). Patients' experiences of this have not been researched in IBD.

Methods

Semi-structured interviews were conducted with adults with Crohn's Disease from out-patient clinics in the United Kingdom. Interviews were audio-recorded and transcribed verbatim, then analysed using thematic analysis.

Results

Fourteen participant interviews were conducted. Three key themes were identified: 1) 'The new normal' established through adaptation and acceptance; 2) 'Energy as a resource' describing attempts to better manage fatigue through planning and prioritising tasks; 3) 'Keeping healthy' encompasses participants' beliefs that 'good health' allows better management of fatigue.

Conclusion

Participants establish a 'new' normality, through maintaining the same or similar level of employment/education activities. However, this is often at the expense of social activities. Further research is required to explore patient led self-management interventions in IBD fatigue.

Sociocultural Considerations for Food-Related Quality of Life in Inflammatory Bowel Disease

The prevalence of inflammatory bowel disease (IBD) is increasing substantially in non-White races and ethnicities in the United States. As a part of promoting quality of life in patients with IBD, the optimization of food-related quality of life (FRQoL) is also indicated. It is known that the practices of food avoidance and restrictive eating are associated with a reduced FRQoL in IBD. Gaining insight into sociocultural influences on FRQoL will aid in the provision of culturally competent interventions to improve FRQoL in patients with IBD.

Food-Related Quality of Life in Children and Adolescents With Crohn's Disease

BACKGROUND

Food-related quality of life (FRQoL) encompasses the psychosocial elements of eating and drinking. The FRQoL of children and adolescents with inflammatory bowel disease has not yet been assessed. This study aimed to evaluate the utility of the validated FR-Qol-29 instrument in children with Crohn's disease (CD).

METHODS

Children diagnosed with CD, a shared home environment healthy sibling, and healthy control subjects 6 to 17 years of age were recruited to this single-center, prospective, cross-sectional study. Children or their parent or guardian completed the FR-QoL-29 instrument. Internal consistency was assessed by completing Cronbach's α. Construct validity was established by correlating the CD FR-QoL-29 sum scores with the Physician Global Assessment and Pediatric Crohn Disease Activity Index scores. The discriminant validity was analyzed using a 1-way analysis of variance, and a Spearman's correlation coefficient test was completed to identify any correlations associated with FRQoL.

RESULTS

Sixty children or their parent or guardian completed the FR-QoL-29 instrument (10 children in each subgroup). The internal consistency was excellent (Cronbach's α = 0.938). The mean FR-QoL-29 sum scores were 94.3 ± 27.6 for CD, 107.6 ± 20 for siblings, and 113.7 ± 13.8 for control subjects (P = .005). Those with higher disease activity had worse FRQoL (Physician Global Assessment P = .021 and Pediatric Crohn Disease Activity Index P = .004). Inflammatory bowel disease FR-QoL-29 sum scores correlated with weight (P = .027), height (P = .035), body mass index (P = .023), and age (P = .015).

CONCLUSIONS

FRQoL is impaired in children with CD. Healthy siblings also have poorer FRQoL than control subjects. Several clinical factors are associated with poorer FRQoL in children with CD including age and level of nutritional risk (weight, height, and body mass index). Further research is required validate these findings and to develop strategies for the prevention or treatment of impaired FRQoL in children with CD.

The Role of Dietary Fibers in the Management of IBD Symptoms

Inflammatory bowel diseases (IBDs) are chronic, progressive, immune-mediated diseases of the intestinal tract. The main subtypes of IBDs are Chron's disease (CD) and ulcerative colitis (UC). The etiology is still unclear, but there are genetic, environmental and host-related factors that contribute to the development of these diseases. Recent literature has shown that dietary therapy is the cornerstone of IBD treatment in terms of management of symptoms, relapse and care of the pathology. IBD patients show that microbiota dysbiosis and diet, especially dietary fiber, can modulate its composition. These patients are more at risk of energy protein malnutrition than the general population and are deficient in micronutrients. So far, no dietary component is considered responsible for IBD and there is not a specific therapeutic diet for it. The aim of this review is to evaluate the role of dietary fibers in CD and UC and help health professionals in the nutritional management of these pathologies. Further studies are necessary to determine the appropriate amount and type of fiber to suggest in the case of IBD to ameliorate psychosocial conditions and patients' quality of life.

Improving Food-Related Quality of Life in Inflammatory Bowel Disease through a Novel Web Resource: A Feasibility Randomised Controlled Trial

Food-related quality of life (FR-QoL) is impaired in inflammatory bowel disease (IBD) and education and support on food-related issues in IBD is needed. This feasibility trial aimed to investigate the effectiveness and acceptability of a web resource in enhancing FR-QoL in newly diagnosed IBD. Patients diagnosed with Crohn's disease or ulcerative colitis in the preceding 12 months, with an impaired FR-QoL, were recruited and randomised to either receive access to the web resource (covering IBD-specific diet concerns) or no access (control group) for 12 weeks, while receiving usual clinical care. FR-QoL, health-related quality of life, psychological outcomes, and clinical disease activity were assessed. Web resource usage was assessed, and patients' experiences of the web resource were investigated in semi-structured interviews. Of 81 patients screened, 50 participants were randomised, 30 to the web resource and 20 to control. FR-QoL increased more in the web resource (+11.7 SD 18.2) than control group (+1.4 SD 20.4) (p = 0.067), while IBD distress reduced in the web resource (-6.8 SD 26.6) and increased in the control group (+8.3 SD 25.5) (p = 0.052), albeit not statistically significantly. End of trial Crohn's disease clinical activity (PRO-2) was significantly lower in the web resource than control group (p = 0.046). Participants most frequently accessed web resource content discussing dietary management of gut symptoms and in semi-structured interviews, reported the website to contain relevant information. This feasibility study demonstrates potential effectiveness of the web resource on improving FR-QoL and psychological outcomes in IBD. An adequately powered effectiveness RCT is feasible to conduct and is now warranted. NCT03884686.

Dietary management of adults with IBD - the emerging role of dietary therapy

Historically, dietitians played a minor part in the management of inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis. Patients were commonly referred for consequences of uncontrolled disease, such as malnutrition and bowel obstruction risk. Today, dietitians are fundamental members of the multidisciplinary IBD team, from educating on the role of diet at diagnosis and throughout the lifespan of a patient with IBD to guiding primary induction therapy. This aspect is reflected in published guidelines for IBD management, which previously placed diet as only a minor factor, but now have diet-specific publications. This Review describes a four-step approach in a dietitian's assessment and management of diet in patients with IBD: (1) identifying and correcting nutritional gaps and dietary imbalances; (2) considering diet to treat active disease with the use of exclusive enteral nutrition (EEN) or emerging diets that could replace EEN; (3) using therapeutic diets to control existing complications of IBD, such as reduced fibre to prevent bowel obstruction in stricturing disease or a fermentable oligosaccharides, disaccharides, monosaccharides and polyols diet to manage co-existing functional gut symptoms; and (4) considering the role of diet in preventing IBD development in high-risk populations.

A Randomized Dietary Intervention to Increase Colonic and Peripheral Blood Short-Chain Fatty Acids Modulates the Blood B- and T-cell Compartments in Healthy Humans

BACKGROUND

Short-chain fatty acids (SCFA) have immune-modulating effects in animal models of disease. However, there is limited evidence that this may occur in humans.

OBJECTIVES

This study aimed to determine the effects of increased exposure to SCFA via dietary manipulation on colonic fermentation and adaptive immune cells.

METHODS

Twenty healthy, young adults (18-45 years of age) underwent a blinded, randomized, cross-over dietary intervention, consuming a high-SCFA producing diet and matched low-SCFA diet for 21 days with 21-day wash-out in between. SCFA were provided through resistant starch, inulin and apple cider vinegar. Blood and 3-day total fecal output were collected at baseline and at the end of each diet. Gas chromatography was used to measure fecal and plasma SCFA. Flow cytometry was used for peripheral blood immuno-phenotyping.

RESULTS

High-SCFA diet was associated with significantly (paired samples Wilcoxon test) higher median [IQR] fecal SCFA concentrations (86.6 [59.0] vs 75.4 [56.2] µmol/g, P = 0.02) and significantly lower median fecal ammonia concentrations (26.2 [14.7] vs 33.4 [18.5] µmol/g, P = 0.04) than the low-SCFA diet. Plasma propionate (9.87 [12.3] vs 4.72 [7.6] µmol/L, P = 0.049) and butyrate (2.85 [1.35] vs 2.02 [1.29] µmol/L, P = 0.03) were significantly higher after high-SCFA diet than after low-SCFA diet. Blood total B cells (184 [112] vs 199 [143] cells/µL, P = 0.04), naive B cells (83 [66] vs 95 [89] cells/µL, P = 0.02), Th1 cells (22 [19] vs 29 [16] cells/µL, P = 0.03) and mucosal-associated invariant T (MAIT) cells (62 [83] vs 69 [114] cells/µL, P = 0.02) were significantly lower after high-SCFA diet than low-SCFA diet.

CONCLUSION

Increasing colonic and peripheral blood SCFA has discrete effects on circulating immune cells in healthy humans following 3-week intervention. Further studies, e.g., in patients with inflammatory disease, are necessary to determine if these changes have immunomodulatory effects, whether these are therapeutically beneficial, and whether prolonged intake might be required.

Food and Inflammatory Bowel Diseases: A scoping review on the impact of food on patients' psychosocial quality of life

Growing bodies of literature show that a controlled diet is important in controlling the symptoms of Inflammatory Bowel Diseases (IBD). This leads patients to avoid foods considered potentially harmful. However, food is not just a nutrient but entails a series of hedonistic, cultural and social values. Thus, there is the concern that having to renounce certain foods might exert an impact on patients' psychosocial quality of life, particularly in younger patients. The aim of this paper is to review the existing literature to address which aspects of the patients' quality of life are affected by food restrictions. A scoping review was carried out. Five different databases were searched in January 2021. Retrieved papers were then screened to only include the relevant studies. Data were extracted and the main results of the studies were charted. A thematic analysis was carried out on the main results to identify the areas of psychosocial quality of life more often impacted by the food restrictions. From the initially identified 1967 unique entries, 14 studies were included. Results show that the perceived importance of food in controlling symptoms is confirmed by patients' accounts. The most common strategy adopted was, thus, the avoidance of trigger foods. The thematic analysis revealed three domains that are impacted by these restrictions: psychological quality of life, social life, family sphere. This study highlights the impact that food restrictions exert on IBD patients' quality of life, and warrants further studies to fill existing gaps, in particular regarding younger patients.

Dietary practices, beliefs and behaviours of adults with inflammatory bowel disease: a cross-sectional study

BACKGROUND

It is widely accepted that there is an association between diet and inflammatory bowel disease (IBD). Diet may play a role in disease pathogenesis but also in treatment and management of IBD. There is an increased interest in dietary aspects of people with IBD.

AIMS

To investigate dietary practices, beliefs and behaviours of adults with IBD in Ireland.

METHODS

An online questionnaire was adapted to explore dietary practices, beliefs and behaviours of people with IBD, and to identify any dietary modifications made due to their IBD.

RESULTS

A total of 475 participants (female n = 354, male n = 121) took part in this study, 62% had Crohn's disease and 38% had ulcerative colitis. Dietary restrictions were imposed in the hope of preventing a relapse by 85% of participants. The most reported foods avoided included fatty foods (68%), spicy foods (64%) and raw vegetables or fruit (58%). Low fibre white plain foods (74%) appeared to improve symptoms during a relapse. Participant's appetites were higher during remission (8.36, SD =  ± 1.95), compared to during relapse (3.71, SD =  ± 2.32) (P ≤ 0.001). Almost three-quarters (73%) avoided the same menu as others living in their household and 56% avoided eating out to prevent or for fear of causing a relapse. Additionally, 70% avoided food or drink they liked to try prevent a relapse.

CONCLUSION

These findings provide important insights into the dietary practices, beliefs and behaviours of adults with IBD. Its evident diet plays an important role, and our findings reiterate the importance of patient education and support.

Food-related quality of life in inflammatory bowel disease: measuring the validity and reliability of the Turkish version of FR-QOL-29

Purpose

Food-related quality of life is considerably impaired in patients with inflammatory bowel disease (IBD) and should be widely measured in research and clinical practice. This study aims to translate the FR-QoL-29 instrument to the Turkish language and evaluate its validity and reliability in Turkish patients with IBD.

Methods

The FR-QoL-29 was forwards and backwards translated into Turkish and the validity and reliability of the FR-QoL-29-Turkish measured at two tertiary hospitals in Ankara, Turkey. Participants completed four questionnaires regarding: sociodemographic; clinical (disease type and activity), and nutritional characteristics (MUST) together with FR-QoL-29-Turkish. In addition, 30 patients repeated the questionnaires after two weeks. collected. Pearson correlation coefficients and Cronbach α were used to assess reliability and validity (p < 0.05).

Results

A total of 180 participants with IBD (78 Crohn’s disease, 102 ulcerative colitis), with a mean age of 45.9 ± 12.5 years, were included. Bartlett's sphericity test was statistically significant (p < 0.001), meeting the prerequisite for factor analysis, and the adequacy of the sample size for factor analysis was confirmed by a high Kaiser–Meyer–Olkin (KMO = 0.92). Validity was confirmed by factor loadings ranging from 0.310 to 0.858. Item-total score correlations ranged from 0.258 to 0.837 and Cronbach’s α coefficient was 0.96 for the whole questionnaire indicating high internal consistency.

Conclusions

FR-QoL-29-Turkish is a valid and reliable measure of food-related quality of life in IBD patients with Turkish language. The FR-QoL-29-Turkish gives a comprehensive overview of the main aspects of food quality of life and can be used as a useful tool in both research and clinical practice.

Optimal Design of Clinical Trials of Dietary Interventions in Disorders of Gut-Brain Interaction

There is accumulating evidence for the fundamental role of diet in the integrated care of disorders of gut-brain interaction. Food is a complex mixture of components with individual, synergistic, and antagonistic effects, compared with the relative purity of a pharmaceutical. Food is also an inherent part of individuals' daily lives, and food choice is strongly tied to food preferences, personal beliefs, cultural and religious practices, and economic status, which can influence its ability to function as a therapeutic intervention. Hence, randomized controlled trials of dietary interventions carry unique methodological complexities that are not applicable to pharmaceutical trials that if disregarded can pose significant risk to trial quality. The challenges of designing and delivering the dietary intervention depend on the type of intervention (i.e., nutrient vs food supplementation or whole-diet intervention). Furthermore, there are multiple modes of delivery of dietary interventions, each with their own advantages (e.g., the high precision of feeding trials and the strong clinical applicability of dietary counseling trials). Randomized placebo-controlled trials of dietary interventions are possible with sufficient attention to their design and methodological nuances. Collaboration with experts in nutrition and dietetics is essential for the planning phase; however, even with expert input, not all challenges can be overcome. Researchers undertaking future dietary trials must be transparent in reporting these challenges and approaches for overcoming them. This review aims to provide guiding principles and recommendations for addressing these challenges to facilitate the conduct and reporting of high-quality trials that inform and improve clinical practice.

The Role of Diet and Gut Microbiota in Regulating Gastrointestinal and Inflammatory Disease

Diet is an important lifestyle factor that is known to contribute in the development of human disease. It is well established that poor diet plays an active role in exacerbating metabolic diseases, such as obesity, diabetes and hypertension. Our understanding of how the immune system drives chronic inflammation and disease pathogenesis has evolved in recent years. However, the contribution of dietary factors to inflammatory conditions such as inflammatory bowel disease, multiple sclerosis and arthritis remain poorly defined. A western diet has been associated as pro-inflammatory, in contrast to traditional dietary patterns that are associated as being anti-inflammatory. This may be due to direct effects of nutrients on immune cell function. Diet may also affect the composition and function of gut microbiota, which consequently affects immunity. In animal models of inflammatory disease, diet may modulate inflammation in the gastrointestinal tract and in other peripheral sites. Despite limitations of animal models, there is now emerging evidence to show that anti-inflammatory effects of diet may translate to human gastrointestinal and inflammatory diseases. However, appropriately designed, larger clinical studies must be conducted to confirm the therapeutic benefit of dietary therapy.
