Background: Disorders of gut-brain interaction (DGBI) predominate in women, but little is known about sex differences in menses-related or menopause symptoms.
Methods: Using data from the Rome Foundation Global Epidemiology Survey, we assessed Rome IV DGBI symptoms in individuals in 26 countries who met criteria for ≥ 1 of 5 DGBI: irritable bowel syndrome (IBS), functional dyspepsia (FD), functional constipation (FC), functional diarrhea (FDr), or functional bloating (FB). Participants included pre- and post-menopausal women with DGBI and age-matched men.
Background: Irritable bowel syndrome (IBS) and functional dyspepsia (FD) are common disorders of gut-brain interaction (DGBI). The Rome IV criteria are the gold standard for research when diagnosing DGBI. However, bothersomeness, or the degree to which symptoms are distressing or disruptive to a person's daily life, is a potential treatment-seeking motivator that is not assessed by the Rome criteria.

Objective: This study aimed to compare the global prevalence of DGBI-compatible symptom profiles in adults with and without self-reported organic GI diseases or DM.
Methods: Data were collected in a population-based internet survey in 26 countries, the Rome Foundation Global Epidemiology Study (n = 54,127).
Background & Aims: Current classification systems for irritable bowel syndrome (IBS) based on bowel habit do not consider psychological impact. We validated a classification model in a UK population with confirmed IBS, using latent class analysis, incorporating psychological factors. We applied this model in the Rome Foundation Global Epidemiological Survey (RFGES), assessing impact of IBS on the individual and the health care system, and examining reproducibility.

Aim: To compare prevalence rates for 22 DGBI and 24 primary symptoms, by age, using the Rome Foundation Global Epidemiology (RFGES) study dataset.
Objective: Using the large Rome Foundation Global Epidemiology Survey dataset, the aim of this study was to evaluate the construct and convergent validity and internal consistency of the PHQ-4 across both gastrointestinal and non-gastrointestinal condition cohorts. Another aim was to provide descriptive information about the PHQ-4 including means, confidence intervals and percentage of caseness using a large representative sample.
Methods: A cross-sectional survey was conducted in 26 countries.
Background: The Rome Foundation Global Epidemiology Study (RFGES) found that 40.3% of adults in 26 internet-surveyed countries met Rome IV criteria for disorders of gut-brain interaction (DGBI). However, additional people not meeting DGBI criteria may also be burdened by frequent gastrointestinal symptoms.
View Article and Find Full Text PDFBackground: Little is known about changes in gastrointestinal symptoms compatible with disorders of gut-brain interaction (DGBI) with increasing age at the population level. The objective of this study was to describe the patterns of DGBI in individuals 65 years of age and above and contrasting them with those of younger adults.
Methods: A community sample of 6300 individuals ages 18 and older in the US, UK, and Canada completed an online survey.

Introduction: This study focused on defining the global prevalence of clinically relevant levels of psychological distress and somatic symptoms and the prevalence of coexistence between these symptoms and disorders of gut-brain interaction (DGBI). We also analyzed how clinically relevant psychological distress and somatic symptoms and coexistent DGBI are associated with health-related outcomes.
Methods: We included a representative sample of 54,127 adult participants (49.
Background: Disorders of Gut-Brain Interaction (DGBI) are highly prevalent worldwide, but their effect on work productivity has not gained much attention.
Aims And Methods: We aimed to compare work productivity and activity impairment (WPAI) in persons with and without DGBI in a large population-based cohort and identify factors independently associated with WPAI in subjects with DGBI. Data were collected from Germany, Israel, Italy, Japan, the Netherlands, Poland, Spain and Sweden via Internet surveys as part of the Rome Foundation Global Epidemiology Study.
Background & Aims: Bloating is a common symptom in the general population and among disorders of gut-brain interaction, although its prevalence has not been well characterized. The aim of this study was to report the prevalence of bloating as a symptom in the worldwide population and to identify factors associated with this symptom in the general population.
Methods: Rome Foundation Global Epidemiology Study internet survey data were analyzed.
Background: The aims were to use Japanese data from the Rome Foundation Global Epidemiological Study (RFGES) to test the hypotheses that severity of gastrointestinal (GI) symptoms and psychosocial disturbance are ordered as Rome IV irritable bowel syndrome (IBS) > Rome III IBS > DGBI, not IBS > others.
Methods: Subjects were 2504 Japanese in the RFGES. We assessed DGBI/IBS diagnoses with Rome IV/III, IBS Symptom Severity Scale (IBS-SSS), Patient Health Questionnaire (PHQ) for anxiety/depression and non-GI somatic symptoms, PROMIS-10 for quality of life (QOL), Work Productivity and Activity Impairment (WPAI) Questionnaire, parts of Self-reported IBS Questionnaire (SIBSQ) for meal effect and stress effect, Food Frequency Questionnaire, and medication questions.
Background: The Rome Foundation Global Epidemiology Study on the disorders of gut-brain interaction (DGBI) was used to assess the national prevalence of all 22 DGBI, the percentage of respondents meeting diagnostic criteria for at least one DGBI, and the rates of comorbid anxiety, depression, and somatization in Australia and 25 other countries.
Methods: The survey was conducted in Australia and 25 other countries through the Internet and included the Rome IV Diagnostic Questionnaire and an in-depth supplemental questionnaire.
Key Results: Two thousand thirty-six Australian adults completed the survey nationwide: mean age 47.
Background: Previous epidemiologic studies in Sweden have only covered some of the disorders of gut-brain interaction (DGBI) and are not representative of the general population. This study aimed to define the prevalence and impact of DGBI in Sweden.
Methods: We used Swedish data from the Rome Foundation Global Epidemiology Study which include information on DGBI diagnoses, psychological distress, quality of life (QoL), healthcare utilization, and the impact of stress on GI symptoms.
Background: There are minimal epidemiological data comparing the burden of disorders of gut brain interaction (DGBI) in the UK with other countries. We compared the prevalence of DGBI in the UK with other countries that participated in the Rome Foundation Global Epidemiology Study (RFGES) online.
Methods: Participants from 26 countries completed the RFGES survey online including the Rome IV diagnostic questionnaire and an in-depth supplemental questionnaire with questions about dietary habits.
Background And Aims: The Rome Foundation Global Epidemiology Study (RFGES) assessed the prevalence, burden, and associated factors of Disorders of Gut-Brain Interaction (DGBI) in 33 countries around the world. Achieving worldwide sampling necessitated use of two different surveying methods: In-person household interviews (9 countries) and Internet surveys (26 countries). Two countries, China and Turkey, were surveyed with both methods.
View Article and Find Full Text PDFBackground: The Rome Foundation carried out a worldwide epidemiology study on DGBI according to the Rome IV criteria in 33 countries, including Belgium. DGBI prevalence varied between continents and countries, but prevalence differences within language groups in a single country have not yet been described.
Methods: We analyzed the prevalence rates of 18 DGBI and their psychosocial impact in Belgium in the French and Dutch language groups.
Background: There is no term for bloating in Spanish and distension is a very technical word. "Inflammation"/"swelling" are the most frequently used expressions for bloating/distension in Mexico, and pictograms are more effective than verbal descriptors (VDs) for bloating/distension in general GI and Rome III-IBS patients. However, their effectiveness in the general population and in subjects with Rome IV-DGBI is unknown.
