The IBS-Quality of Life instrument showed moderate correlations with the FAST symptom abdominal swelling/distension (0.313-0.416, P < 0.05). The consumption of a high fermentable oligosaccharides, disaccharides, monosaccharides, and polyols meal was associated with participants with IBS-D experiencing abdominal bloating and participants with IBS-C not experiencing abdominal swelling (P < 0.05). The consumption of fiber was correlated with abdominal fullness and bloating in participants with IBS-C (P < 0.05). Discussion: The FAST diary validly measures gastrointestinal symptoms as they occur in people with IBS and correlates these symptoms with specific aspects of diet.]]> Wed 15 Dec 2021 15:35:15 AEDT ]]> Mechanisms of food-induced symptom induction and dietary management in functional dyspepsia https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:45352 Thu 27 Oct 2022 11:46:53 AEDT ]]> Diabetes mellitus is an independent risk factor for a greater frequency of early satiation and diarrhea at one and three years: Two prospective longitudinal population-based studies https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:50509 3 bowel motions a day (OR 1.50, 95% CI 1.08, 2.07, p = 0.02; OR = 1.67, 95% CI 1.11, 2.51, p = 0.01), and loose stools (OR 1.40, 95% CI 1.04, 1.90, p = 0.03; OR = 1.68, 95% CI 1.13, 2.51, p = 0.01) at the 1- and 3-year follow-ups, respectively.

Discriminant validity along with test–retest reliability was assessed. The time taken to perform a clinical assessment with and without the SAGIS was recorded along with doctor satisfaction with this tool. Results: Exploratory factor analysis conducted on the derivation sample suggested five symptom constructs labeled as abdominal pain/discomfort (seven items), gastroesophageal reflux disease/regurgitation symptoms (four items), nausea/vomiting (three items), diarrhea/incontinence (five items), and difficult defecation and constipation (2 items). Confirmatory factor analysis conducted on the validation sample supported the initially developed five-factor measurement model (χ²₁₉₃=892.2, p < 0.0001, χ²/df = 4.6, CFI = 0.90, TLI = 0.88, RMSEA = 0.08). All symptom groups demonstrated differentiation between disease groups. The SAGIS was shown to be reliable over time and resulted in a 38% reduction of the time required for clinical assessment. Conclusions: The SAGIS instrument has excellent psychometric properties and supports the clinical assessment of and symptom-based categorization of patients with a wide spectrum of gastrointestinal symptoms.]]> Sat 24 Mar 2018 08:43:15 AEDT ]]> STW5 (Iberogast) herbal therapy and functional gastrointestinal symptoms https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:14112 Sat 24 Mar 2018 08:26:02 AEDT ]]> Prospective diary evaluation of unexplained abdominal pain and bowel dysfunction: a population-based colonoscopy study https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:12383 Sat 24 Mar 2018 08:18:00 AEDT ]]> Eosinophilic gastroenteritis https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:10428 Sat 24 Mar 2018 08:13:17 AEDT ]]> A randomly selected population sample undergoing colonoscopy: prevalence of the irritable bowel syndrome and the impact of selection factors https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:18602 Sat 24 Mar 2018 08:01:04 AEDT ]]> Evidence against routine testing of patients with functional gastrointestinal disorders for celiac disease: a population-based study https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:28387 Sat 24 Mar 2018 07:36:00 AEDT ]]> Gastrointestinal symptoms negatively impact on sleep quality among obese individuals: a population-based study https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:26351 Sat 24 Mar 2018 07:35:53 AEDT ]]> Multi-dimensional gastrointestinal symptom severity index: validation of a brief GI symptom assessment tool https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:28111 a priori hypothesized six-factor measurement model (X²(428) = 1462.98; P<0.001; GFI = .88; RMSEA = .051).
